Typesof FabricLays
Based onConstruction:
1.Straight Lay
2.SteppedLay
Based on the Direction of Spreading:
1.All faceup/down
2.Faceto face
3.Zig-Zag
BasedontheConstruction
Straight Lay
Eachply of the fabric isspread in full length as
per the length of the marker.
Stepped Lay
Eachply of the fabric is not spread in full
length, that means they are arranged insteps
BasedontheDirectionofSpreading
All faceup/down
This type of lay is suitable for wide and open
face side of each ply of the fabric is placed
either of the top side or bottom side
Face to Face
The front side of the ply of the fabric is placed
face to face in pairs and for making the lay
Zig Zag Lay
Fabric spreading starts from one end asper the
marker length and reach the other end and
withoutcutting fabric end
MethodofFabricSpreading
Manual Method
a. Byhand
b. Byhook
c.Spreadingtruck with the help of operator.
Mechanical method
a.Semi automatic
b. Full automatic
ManualMethod
By Hand: Fabric roll is spreadedon the table by two laborers according to the
length & width of marker. Sometimes it is done by entering arod which is made
by wood or metal in the center paper table which is present in the center of the
fabric roll.
By Hook: In this processthe top of the table on which the fabric is spreaded is
set at 10º angle perpendicularly.The hook which placed on the upper face of the
table is 15cmlong and the hook is joined with one end of selvedge of the fabric.
Spreading truck with the help of operator: There is aspreading truck on the
one end of the spreading table in which the fabric roll is placed.Then the truck
is operated by hand from one end to the other end of the table & with the same
time the fabric is open out from the fabric roll and the fabric is spreaded
according to the length and width.

width and start spreading from the edge of fabric alreadyspreadby
overlapping.Thiskind of overlappingiscalledsplice.
• Therearetwo types of splice:
 Straight lineSplice.
InterlockSplice.
Splice
Straight LineSplice
This type of spliceis marked by astraight line
along the width of the spreadingtable.
Interlock Splice
This type splice is marked with two straight
lines along the width which are again joined
by crosslines.

Types of Fabric Package
There are different types of fabric package used in apparel industry, which are pointed out in the below:
 Open fabric roll,
 Folded fabric roll,
 Tubular knitted fabric roll,
 Hanging fabric package,
 Folded fabric cuttled.
1. Open fabric roll:
Open fabric package or roll is formed by the open width fabric which is used for making woven garments. In
most of the time, fabric is supplied by wrapping over a tube in garments manufacturing industry which is about
7 to 8cm diameter. Sometimes fabric rolls are varied from 75cm to 3 meters where as the length of fabric is
usually 100 meters or more. Open fabric roll package is perfect for both manual and machine spreading.
2. Folded fabric roll:
Folded fabric roll or package is generally used by retail seller. Here, fabric is wrapped over
1-2cm thick and hard board where as the fabric width is 70-80cm. this type of fabric cannot
be spread by using spreading machine.
3. Tubular knitted fabric roll:
In garments manufacturing industry, Most of the knit fabrics are found in tubular form and
those are supplied in roll form. Normally tube roll have the same width as the garments
width such as polo shirt or T-shirt. Here, fabric spreading machine is used to spread fabric
from the roll or package.
4. Hanging fabric package:
It is used for both woven and knitted fabrics but especially for velvet or pile fabrics. Here,
fabrics are placed in a special type of frame according to the length and width and should
kept in hanging form so that the pile is not crushed. Manual spreading is used for this types
of fabric package.
Requirements of Fabric Cutting
Precision of cut
To ensure the cutting of fabric accurately according to the line drown
of the marker plan.
Clean edge
By avoiding the fraing out of yarn from the fabric edge. Cutting edge
must be smooth clean. Knife must be sharp for smooth or clean
edge. Infused edge
During fabric cutting, the friction between the fabric and blade; the
blade produces temperature in the temperature may be up to
3000c.
Support of the lay
Surface of the cutting table depends on methods of fabric cutting.
The table surface should be capable to support the lay as well as
to ensure that all the plies are cut at a time during fabric cutting.

Interlining
Interlining is a very important in apparel manufacturing. Interlining is one
kind of accessories that is used between the two layers of fabric in a garment.
To keep the different component or part of apparel in a desired shape, a kind of
fabric is used between the two ply of fabric by sewing or fusing is called
interlining.
Generally, interlinings are soft, thick, and flexible. It is made cotton, nylon,
polyester, wool and viscose. Sometimes finishing is necessary to improve its
properties i.e. shrink resist finish, crease resist finish.
FUNCTIONSOFINTERLINING:
 To support thegarment.
 To control the shape of the garment.
 To control the area of the apparel.
 To reinforce the components of the garment.
 To make the apparel beautiful, strong and attractive.
 To ensure the anticipated look, quality and effect of the fabric.
 To improve garment performance.
 Uses of Interlinings: Interlining is generally used in collar, cuffs, waist band,
front facing of coat, outerwear plackets, jackets, blazers etc.
TYPESOFINTERLINING
There are mainly two types of interlining are as follows:
Sewn interlining or non-fusible interlining.
Fusible interlining
NON FUSIBLEINTERLINING
 The interlining which is used between two layers of fabrics directly by sewing
without heat and pressure is called non-fuse interlining.
 This type of interlining is also called sewn interlining or non- fusible interlining.
 For the preparation of sewn interlining a piece of fabric is treated
with starch and allowed to dry and finally sewn with main fabric.
Non fuse interlining is used for special case.
Non-fuse interlining use in “Flame Retardant” apparel.
It is used for making apparel for fire service people.
Specially used in embroidery machine.
Advantages of Non-fusibleInterlining:
 To make flame retardant garment
 Simple and easy technique.
 No elaborate machine is required.
 Possible to use in steel or re-rolling or highly heated
industry.
Disadvantages of Non-fusibleInterlining:
 Quality is not good.
 Not suitable for large production.
 More time required.
 High work load &labor cost.
FUSIBLEINTERLINING:
It is most used interlining. The interlining which is used
between two layers of fabrics by applying heat and
pressure for a certain time is called Fusible Interlining.
Fusible interlining is used for all kinds of apparel.
Also it is used in “Ready to wear” and “Bespoke garment”. It is
verypopular.
Advantages of Fusible Interlining:
 Application process is very easy.
 It has high productivity.
 Fusing time isless.
 It is cheap.
 Performance is verygood.
Disadvantagesof Fusible Interlining:
 High temperature isrequired.
 Special care is needed during attaching interlining.
Requirement of Fusing
Fusible interlining contains the below properties:
1.Here, the fusing is done by using perfect temperature so that there is no hampering
of fabric color.
2.The maximum temperature of fusing should not be more than 175°
3.The minimum temperature of this interlining should not be less than 110°
4.The minimum temperature should be applied during fusing otherwise it will create problem in
the bonding between garments fabric and interlining during washing or end using of garments.
5.The bond of fusible interlining should not be opened or hampered due to washing or
dry cleaning.
6.After completing this type of interlining it should contain the stiffness and drape properties
of garments.
7.The color of fusible interlining must be white or transparent, but it can be different in color
according to the fusing requirements.
8.This type of interlining should be done as that the color of garment cannot be changed due to
the color of interlining.
9.The interlining should not be toxic to the human body during the end use of garments.
TYPESOFFUSIBLEINTERLINING:
On the basis of resin coating and its properties fusible
interlining can be classified as follows:
i. Polyethylene coated interlining
ii. Polyamide coated interlining
iii. PVC coated interlining
iv. Polyester coated interlining
v. Polypropylene coated interlining
vi. PVAcoated interlining
PolyethyleneCoated Interlining:
 Polyethylene is used asresin coating.
 The effect of varying the density of the
resin is to give a greater resistance to
dry cleaning solvents and a higher
softening pointwith increasing density.
 This type of interlining is used in collar,
cuff of shirt.
 The fabric attached with this type of
interlining can be washed inwater.
Polyamide Coated Interlining:
Polyamide is used as resin
coating.
Poly-amides
widely used
are very
in dry
cleanable garments.
High temperature fusing
is done for the garments,
which are washed with
water at 60ºc.
PVC Coated Interlining:
Poly vinyl chloride isused as resincoating
This type is suitable for both dry cleanable and washable
garments.
PVC coated interlining
is widely
making the
used for
coat type
garments.
Polyester Coated Interlining:
Polyester is used as resin coating
Polyester resins are used in dry
cleanable and washable garments
because polyester is less water
absorbent than polyamide.
It can be used as in all types of
garments
This is called idealinterlining
Available in market but costly in
price
Polypropylene Coated Interlining
Polypropylene coated
interlining. The resin is
similar to the properties
of polyethylene coated
interning
Comparatively high
temperature fusing is
done.
The fabric attached with
this interlining can be
washed with water
PVACoatedInterlining
PVAcoated interlining. Poly vinyl acetate is used
as resin coating
PVA coated interlining is not dry cleanable and it
has limited washability
Low temperature and pressure is required.
Basically it is used between the leather and fur
materials.
The resin is normally in the form of a continuous
plasticized coating on the base fabric.
This type is rarely used in garments industry
Conditions of Fusing
• Temperature: There is a limited range of temperatures that are
effective for each type of resin. Too high a temperature causes the
resin to become too viscous, which could result in the resin being
forced through to the right side of the cloth
• Time: Time is the only time element of any value during the fusing
process is when the top cloth and fusible are under pressure in the
heating zone of the machine.This time cycle for a particular fusible is
determined by :
• Whether the fusible has a high –or low melt resin.
• If a high or heavy substrate is being used.
• The nature of the top cloth being used, thick or thin, dense or open.
• Pressure: When the resin is viscous, the pressure is applied to the
top cloth and fusible assembly to ensure that :
• Full contact is made between the top cloth and fusible.
• Heat transfer is at the optimum level.
• There is an even penetration of the viscous resin into the fibers of the top
cloth.
• Cooling: Enforced cooling is used so that the fused assemblies can
be handled immediately after fusing. Cooling can be induced by
various systems. Including water-cooled plates, compressed air
circulation, and vacuum.

(Sir Ashraful Alam) Full PDF Apparel Manufacturing I Sheet Part-2

  • 1. Apparel Manufacturing I (Term Final) ----Presented By MohammadAshrafulAlam
  • 2. Syllabus - Fabric Spreading Section - Fabric Cutting Section - Interlining - Application of Computer in Apparel Manufacturing
  • 3. Objects of FabricSpreading Tocut garments in bulk and saving in fabric. Tosavecutting time by cutting many plies at atime. Toensureevery ply plain and flat. Toreduce manufacturing cost by cutting in proper way by ensuringpro per fabric spreading. Correctly aligned asto length and width At correcttension
  • 4. Requirementsof SpreadingProcess Alignment offabric piles. Fabric must beflat. Elimination offabric flaws. Correct plydirection. Correct plytension. Elimination ofstatic electricity. Avoidance of fusion of plies during cutting. Avoidance of distortion in spread Matching checksor stripes . Easyseparate of the cut lay into bundles.
  • 5. Typesof FabricLays Based onConstruction: 1.Straight Lay 2.SteppedLay Based on the Direction of Spreading: 1.All faceup/down 2.Faceto face 3.Zig-Zag
  • 6. BasedontheConstruction Straight Lay Eachply of the fabric isspread in full length as per the length of the marker. Stepped Lay Eachply of the fabric is not spread in full length, that means they are arranged insteps
  • 7. BasedontheDirectionofSpreading All faceup/down This type of lay is suitable for wide and open face side of each ply of the fabric is placed either of the top side or bottom side Face to Face The front side of the ply of the fabric is placed face to face in pairs and for making the lay Zig Zag Lay Fabric spreading starts from one end asper the marker length and reach the other end and withoutcutting fabric end
  • 8. MethodofFabricSpreading Manual Method a. Byhand b. Byhook c.Spreadingtruck with the help of operator. Mechanical method a.Semi automatic b. Full automatic
  • 9. ManualMethod By Hand: Fabric roll is spreadedon the table by two laborers according to the length & width of marker. Sometimes it is done by entering arod which is made by wood or metal in the center paper table which is present in the center of the fabric roll. By Hook: In this processthe top of the table on which the fabric is spreaded is set at 10º angle perpendicularly.The hook which placed on the upper face of the table is 15cmlong and the hook is joined with one end of selvedge of the fabric. Spreading truck with the help of operator: There is aspreading truck on the one end of the spreading table in which the fabric roll is placed.Then the truck is operated by hand from one end to the other end of the table & with the same time the fabric is open out from the fabric roll and the fabric is spreaded according to the length and width.
  • 10. Mechanicalmethod Semi automatic: Semi automatic machine is working almost similar to Hand process with spreading track process becausethis methodsworking technique and working prouder are same but this process are working by electric motor
  • 11. Advantage of semi automatic……  The maximum fabric width which can be handled is normally 2m although extra wide machines are capable of handling up to 3m.  Auto ply cutting device here.  Auto plies counting arrangements.  Auto catcher to hold the ends of the ply.  Auto fabric tensioning device.  Auto fabric leveling device,  Photo electric guide for selvedge alignment.  Fabric fault detector.  A platform is provided on which operator stands.  Maximum weight of the fabric roll can be 80kg to 675kg.  Maximum height of spread is 25cm.  Maximum spread speed 100m/min.  It has also rolled turning arrangement.  Auto loading and unloading device.  It is very useful.
  • 12. disadvantage • More time is required here. • It has needed higher labor cost. • It cannot be possible to make desired fabric spreading technique by using this method. • There is no sensor in the spreading head. • Any kinds of fabric cannot be spread here.
  • 13. Mechanicalmethod Full automatic :Full automatic fabric spreading machine is the improvement of semi-automatic spreadingmachine.There arealot of advantages of this machine to make fabric lay. Because,this spreading machine is operated by controlling with the help of micro processor androbot.
  • 14. advantages High production is achieved by mechanical method. Arrangements available for counting number of plies. Cutting devices available at the end of each ply. Auto leveler available to flat the fabric. Photo-cells available for selvedge alignment. Speed controller available to ensure uniform tension. Grinding wheel available with the cutter. Fabric loading and unloading device available for nonstop spreading. A platform is available for the operator by which he/she can sit or stand during spreading. Low labor cost. Suitable for large scale apparel industry.
  • 15. Splice • During the fabric spreading process,if the fault detector machinegets anyfault or damageon the fabric then the fabric must be cut by width and start spreading from the edge of fabric alreadyspreadby overlapping.Thiskind of overlappingiscalledsplice. • Therearetwo types of splice:  Straight lineSplice. InterlockSplice.
  • 16. Splice Straight LineSplice This type of spliceis marked by astraight line along the width of the spreadingtable. Interlock Splice This type splice is marked with two straight lines along the width which are again joined by crosslines.
  • 18. Types of Fabric Package There are different types of fabric package used in apparel industry, which are pointed out in the below:  Open fabric roll,  Folded fabric roll,  Tubular knitted fabric roll,  Hanging fabric package,  Folded fabric cuttled. 1. Open fabric roll: Open fabric package or roll is formed by the open width fabric which is used for making woven garments. In most of the time, fabric is supplied by wrapping over a tube in garments manufacturing industry which is about 7 to 8cm diameter. Sometimes fabric rolls are varied from 75cm to 3 meters where as the length of fabric is usually 100 meters or more. Open fabric roll package is perfect for both manual and machine spreading.
  • 19. 2. Folded fabric roll: Folded fabric roll or package is generally used by retail seller. Here, fabric is wrapped over 1-2cm thick and hard board where as the fabric width is 70-80cm. this type of fabric cannot be spread by using spreading machine. 3. Tubular knitted fabric roll: In garments manufacturing industry, Most of the knit fabrics are found in tubular form and those are supplied in roll form. Normally tube roll have the same width as the garments width such as polo shirt or T-shirt. Here, fabric spreading machine is used to spread fabric from the roll or package. 4. Hanging fabric package: It is used for both woven and knitted fabrics but especially for velvet or pile fabrics. Here, fabrics are placed in a special type of frame according to the length and width and should kept in hanging form so that the pile is not crushed. Manual spreading is used for this types of fabric package.
  • 20. Requirements of Fabric Cutting Precision of cut To ensure the cutting of fabric accurately according to the line drown of the marker plan. Clean edge By avoiding the fraing out of yarn from the fabric edge. Cutting edge must be smooth clean. Knife must be sharp for smooth or clean edge. Infused edge During fabric cutting, the friction between the fabric and blade; the blade produces temperature in the temperature may be up to 3000c. Support of the lay Surface of the cutting table depends on methods of fabric cutting. The table surface should be capable to support the lay as well as to ensure that all the plies are cut at a time during fabric cutting.
  • 21. TYPES OF CUTTING METHOD  Fully Manual  Handoperated scissor  Manually Operated Power Knife  Straight knife  Band knife  Round knife  Die cutting  Notcher  Drill  Computerized Methods Of Fabric Cutting  Computer controlled knife cutting  Cutting by Laser beam  Cutting by Water jet  Cutting by Plasma torch
  • 22. HAND OPERATED SCISSOR Features:  First & oldest method of fabric cutting  Used for cutting one or two plies of fabric  Available to cut the fabric from left to right or right to left  Canbe cut by scissor  Needs more time & contain high cost  Used in tailoring & household purpose to cut fabric
  • 23. STRAIGHT KNIFE Features:  The elements of straight knife consistsof: 1. An electric motor 2. Stand 3. Abase plate usually on rollers 4. Handle 5. Knife 6. Knife Guard 7. Wheel  Knife is driven by electricpower  Grinding wheel is present to sharp the knife duringcutting  Blade edge: straight edge, wave edge, saw edge, serratededge  Straight edge is mostlyused  Blade stroke 2.5 to 4.5cm  Can cut heavy fabric such as canvas &denim
  • 24. STRAIGHT KNIFE Working Principal:  Two kind of powers are required to operate a Straight Knife  Motor power drive the reciprocating knife  Operator power drives the knife through the lay  The motor power needed is determined by  Height of the lay  Construction of the fabric  Curvature of the line being cut  Stroke of the blade  Greater power of the motor, greater blade movement to cut the fabric
  • 25. STRAIGHT KNIFE Advantage:  Comparatively cheap & transferred easily from one place to another place  Higher lay of fabric can be cut easily  Round corner can be cut more precisely then even round knife  Production speed is very good & fabric can be cut from any angle Disadvantage:  Some time deflection may occur due to the weight o the motor  Knife deflection is high in risk, when lay height is too high  Sometime accident may happen

  • 42. Interlining Interlining is a very important in apparel manufacturing. Interlining is one kind of accessories that is used between the two layers of fabric in a garment. To keep the different component or part of apparel in a desired shape, a kind of fabric is used between the two ply of fabric by sewing or fusing is called interlining. Generally, interlinings are soft, thick, and flexible. It is made cotton, nylon, polyester, wool and viscose. Sometimes finishing is necessary to improve its properties i.e. shrink resist finish, crease resist finish.
  • 43. FUNCTIONSOFINTERLINING:  To support thegarment.  To control the shape of the garment.  To control the area of the apparel.  To reinforce the components of the garment.  To make the apparel beautiful, strong and attractive.  To ensure the anticipated look, quality and effect of the fabric.  To improve garment performance.  Uses of Interlinings: Interlining is generally used in collar, cuffs, waist band, front facing of coat, outerwear plackets, jackets, blazers etc.
  • 44. TYPESOFINTERLINING There are mainly two types of interlining are as follows: Sewn interlining or non-fusible interlining. Fusible interlining
  • 45. NON FUSIBLEINTERLINING  The interlining which is used between two layers of fabrics directly by sewing without heat and pressure is called non-fuse interlining.  This type of interlining is also called sewn interlining or non- fusible interlining.  For the preparation of sewn interlining a piece of fabric is treated with starch and allowed to dry and finally sewn with main fabric. Non fuse interlining is used for special case. Non-fuse interlining use in “Flame Retardant” apparel. It is used for making apparel for fire service people. Specially used in embroidery machine.
  • 46. Advantages of Non-fusibleInterlining:  To make flame retardant garment  Simple and easy technique.  No elaborate machine is required.  Possible to use in steel or re-rolling or highly heated industry. Disadvantages of Non-fusibleInterlining:  Quality is not good.  Not suitable for large production.  More time required.  High work load &labor cost.
  • 47. FUSIBLEINTERLINING: It is most used interlining. The interlining which is used between two layers of fabrics by applying heat and pressure for a certain time is called Fusible Interlining. Fusible interlining is used for all kinds of apparel. Also it is used in “Ready to wear” and “Bespoke garment”. It is verypopular.
  • 48. Advantages of Fusible Interlining:  Application process is very easy.  It has high productivity.  Fusing time isless.  It is cheap.  Performance is verygood. Disadvantagesof Fusible Interlining:  High temperature isrequired.  Special care is needed during attaching interlining.
  • 49. Requirement of Fusing Fusible interlining contains the below properties: 1.Here, the fusing is done by using perfect temperature so that there is no hampering of fabric color. 2.The maximum temperature of fusing should not be more than 175° 3.The minimum temperature of this interlining should not be less than 110° 4.The minimum temperature should be applied during fusing otherwise it will create problem in the bonding between garments fabric and interlining during washing or end using of garments. 5.The bond of fusible interlining should not be opened or hampered due to washing or dry cleaning. 6.After completing this type of interlining it should contain the stiffness and drape properties of garments. 7.The color of fusible interlining must be white or transparent, but it can be different in color according to the fusing requirements. 8.This type of interlining should be done as that the color of garment cannot be changed due to the color of interlining. 9.The interlining should not be toxic to the human body during the end use of garments.
  • 50. TYPESOFFUSIBLEINTERLINING: On the basis of resin coating and its properties fusible interlining can be classified as follows: i. Polyethylene coated interlining ii. Polyamide coated interlining iii. PVC coated interlining iv. Polyester coated interlining v. Polypropylene coated interlining vi. PVAcoated interlining
  • 51. PolyethyleneCoated Interlining:  Polyethylene is used asresin coating.  The effect of varying the density of the resin is to give a greater resistance to dry cleaning solvents and a higher softening pointwith increasing density.  This type of interlining is used in collar, cuff of shirt.  The fabric attached with this type of interlining can be washed inwater.
  • 52. Polyamide Coated Interlining: Polyamide is used as resin coating. Poly-amides widely used are very in dry cleanable garments. High temperature fusing is done for the garments, which are washed with water at 60ºc.
  • 53. PVC Coated Interlining: Poly vinyl chloride isused as resincoating This type is suitable for both dry cleanable and washable garments. PVC coated interlining is widely making the used for coat type garments.
  • 54. Polyester Coated Interlining: Polyester is used as resin coating Polyester resins are used in dry cleanable and washable garments because polyester is less water absorbent than polyamide. It can be used as in all types of garments This is called idealinterlining Available in market but costly in price
  • 55. Polypropylene Coated Interlining Polypropylene coated interlining. The resin is similar to the properties of polyethylene coated interning Comparatively high temperature fusing is done. The fabric attached with this interlining can be washed with water
  • 56. PVACoatedInterlining PVAcoated interlining. Poly vinyl acetate is used as resin coating PVA coated interlining is not dry cleanable and it has limited washability Low temperature and pressure is required. Basically it is used between the leather and fur materials. The resin is normally in the form of a continuous plasticized coating on the base fabric. This type is rarely used in garments industry
  • 57. Conditions of Fusing • Temperature: There is a limited range of temperatures that are effective for each type of resin. Too high a temperature causes the resin to become too viscous, which could result in the resin being forced through to the right side of the cloth • Time: Time is the only time element of any value during the fusing process is when the top cloth and fusible are under pressure in the heating zone of the machine.This time cycle for a particular fusible is determined by : • Whether the fusible has a high –or low melt resin. • If a high or heavy substrate is being used. • The nature of the top cloth being used, thick or thin, dense or open.
  • 58. • Pressure: When the resin is viscous, the pressure is applied to the top cloth and fusible assembly to ensure that : • Full contact is made between the top cloth and fusible. • Heat transfer is at the optimum level. • There is an even penetration of the viscous resin into the fibers of the top cloth. • Cooling: Enforced cooling is used so that the fused assemblies can be handled immediately after fusing. Cooling can be induced by various systems. Including water-cooled plates, compressed air circulation, and vacuum.
  • 59. Available computer technologies Examples of computer systems used in the textile and apparel industry include: Computer Aided Administration (CAA) – computers are used for marketing, sales order processing and stock control. Computer Aided Design (CAD) – computers are used for developing designs, pattern making, pattern grading, marker production and lay planning.
