What is Seam?
A seam is a joint of two pieces of fabric in producing a three -dimensional shape of a garment.
Properties of good seam are,
= Smooth fabric joints
= No Missed or Uneven stitches
= No damage to the material being sewn
= Achievement of strength, elasticity, Durability, security and comfort
= Comfortable while garment is in use
SEAMS DESIGNATION
Each stitched seam is designed numerically by five digits:
0.00.00 refers to the CLASS, 1-8;
0.00.00 refers to the material configuration,
01 to 99;
0.00.00 refers to needle penetrations, material configurations, 01-99.
Seam Classification:
According to British Standard 3870: 1991, seam is classified as-
Class 1- superimposed
Class 2- lapped
Class 3- bound
Class 4- flat
Class 5- decorative/channel
Class 6- edge neatening
Class 7- applied
Class 8- others
* Formed by lapping two pieces of component, they are produced with minimum of two pieces of component.
* One component is limited on one end and the other is limited on the other end. The limited edges of these two components are put in opposite directions.
* Used for: main seaming of denim jackets, jeans, and overalls. Fabrics that will not ravel, unlined garments, side seams of shirts, joining lace to another fabric, attaching patch pockets, decorative finish
Garment dyeing is the cost effectiveness of mass producing identical garments of particular colors.Garment dyeing is the process of dyeing fully fashioned garments (such as pants, pullovers, t-shirts, jeans, sweaters, dresses, bathrobes, casual jackets, shirts, skirts, hosieries) subsequent to manufacturing, as opposed to the conventional method of manufacturing garments from pre-dyed fabrics. A major drawback with this approach is the risk associated with carrying a large inventory of a particular style or color in today's dynamic market. Garment dyeing has been slowly emerging as a process to meet the ephemeral fashion trends adopted by the consumers and new machines and methods have made this process to wear a brighter future for it.The advantage of this process is the cost effectiveness of mass producing identical garments of particular colors.
Quick Response to the market (bar coding etc.,)
Ability to supply a wide range of colorations to the retailer, but only in the shades that are selling
Reduced discounted sales at inventory
Best way to achieved relaxed, casual look .Ability to create special effects such as tie dyed, pigment dyed and washed down in a single process etc.,
A major drawback with this approach is the risk associated with carrying a large inventory of a particular style or color in today's dynamic market.

The basic functions of a needle
Needle Parts
Needle Selection
Types of needle
Needle Size / Thickness
Various effects of wrong sewing needle selection in apparel industry has mentioned in the below:
1. When the needle is finer than sewing thread
2. When the thread is finer than needle
3. When the needle is coarser than required fabric
4. When the needle is finer than required fabric
Needle Parts:
1. Butt
The starting part of bottom edge of needle. Helps for easily attaching of needle with the needle bar or clamp
2. Shank
The bottom thicker part of the needle which is tied in the needle clamp or the needle set screw. It may be cylindrical or flat in size. It supports the needle as a whole by providing additional strength
3. Shoulder
The intermediate section between the shank and the blade of needle. When the needle penetrate through the fabric to reach its lower position, then the shoulder also penetrates through the fabric. As a result it reduces the friction between needle & fabrics by producing a wider hole on fabric.
4. Blade
The needle portion extends from the shank to the eye. This is subjected to the greatest amount of friction and hence heat when it passes through the material. Blade is gradually tapered to tip
5. Long groove(s)
It is a long and thin groove, presents in one side of the needle blade . During up and down of needle through sewing, the sewing thread take place in this groove and reduce the frictions between fabric, needle and thread. It provides a protective channel and reduce possibility of damaging thread due to frictions.
6. Short groove
It is formed on the other side of long groove, towards the shuttle, hook, or looper and it assists in throwing the loop of needle thread
7. Eye
The eye of the needle is present in the bottom end of the blade. Needle thread allowed through this eye is taken to the bottom area. It helps to create loop
8. Scarf (Clearance)
It is a curved slot, a clearance cut in the needle blade just above the eye to permit a closer setting of the shuttle, hook, or looper to the needle. As a result, it is easy to catch the needle loop by the looper hook.
9. Point
It is the part from needle eye to the tip. The point of the needle is shaped to provide the most suitable penetration of the material being sewn according to its nature and the desired stitch effect
10. Tip
The ending edge pf needle is called tip. It helps to penetrate the needle into the fabric and create hole during sewing.

Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
5. Fabric Damage
• A garment product can be rejected due to
damage of fabrics or yarn of fabrics in
the seam line. This is mainly happening due
to wrong needle selection or needle damaging
problem. Fabric may be also damaged in case
of new and fine needles due to wrong
selection of needle size and needle point.
6. Types of Fabric Damage
1.Mechanical Damage
2.Needle heating Damage
7. Mechanical Damage
Mechanical damage is the common in apparel
industry. This damaging of fibers or yarns in
the fabrics by needle is the entire faults of
mechanical damage. Mechanical problem is
the main reason for producing defective
fabric.
10. Causes of Mechanical Damage
Inadequate fabric finishing
Damage needle point or throat plate
Mismatch between needle size & throat plate
11. Remedies of Mechanical Damage
Application
of lubricant
along the
stitch line
before
sewing
12. Continue
• The speed of sewing machine should be
reduced.
• Needle size and point should be properly
selected and needle should be free from fault.
• To test the Sew ability before sewing of fabrics
13. Needle Heating Damage
The temperature in needle due to friction
between needle and fabric is up to 300 ºC –
350 ºC. Needle and fabric both may be
damaged in this temperature.
15. Continue
Needle heat is the result of the friction between the
needle and the fabric during
sewing. The following factors can impact the
amount of heat that is generated:
* Thicker fabrics
* Fabrics with harsher finishes or greater density
* Fabric color or density
* Higher sewing machine speeds
16. Continued
* Needle contact surface
− Larger Needle Sizes have more contact area
− Longer Needle Types have more contact area
− Single grooved needle has more contact area
than double
grooved needles.
− Some needle surfaces generate more friction
than others.
17. Remedies of Needle Heating Damage
• 1. Speed: By reducing
sewing speed so that
there is less generating
of heat to the needle.
But, for large
production this is not
granted.
18. Continue
2 . Special type of
needle:
Teflon coated needle
which has extra
smoothness than
galvanized nickel coated
needle may be used to
reduce temperature.
19. Continue
3. Needle Size and Shape: By changing needle
size, shape and use finer needle so that there
is less generation of heat to the needle.
4. Short Length of sewing: The temperature
generation in needle can be reduced by
sewing of short length instead of long length.
20. CONTINUE
5. Cool Air: By
flowing cool air on
the needle during
sewing so that the
temperature can
be controlled
between 70ºC
22. Conclusion
The identification of fabric damage fault with
image would be clear. It is one of the major
problem during sewing . Most of the defects
occur due to improper needle size, pressure
foot adjustment, throat plate replace etc. If
sewing process can be improved, the quality
of the products will be better.
