1. 9.Technology shaping the Future of Fashion Industry -
Design To Merchandising
• The fashion sector is also one of the largest industries in the global economy with the $2.2T
• Today, fashion technology is growing at a faster pace than ever:
 From robots that sew and cut fabric, to
 AI algorithms that predict style trends, to
 VR mirrors in dressing rooms, technology is automating, personalizing, and speeding up
every aspect of fashion.

4. 10. Computer Aided Manufacture (CAM)
 Uses computer software to control machine tools and machinery in the manufacturing process.
 It is the software code behind the machines that manufacture the products.
 Also, assist in all operations of a manufacturing plant:
 Planning,
 Management
 Transportation and storage.
 Its primary purpose includes:
 Create a faster production process and components
 Tooling with more precise dimensions and material consistency (uses only the required
amount of raw material (thus minimizing waste) and reducing energy consumption).

6. Fabric spreading
 Main operation in garment industry
 Unwinding large fabric rolls onto long, wide tables
in for cutting each piece of garment
During Spreading –
 Alignement of plies,
 Elimination of fabric defects/flaws,
 Correct ply direction,
 Correct ply tension and
 Make fabrics flat and,
crinkle & crease free
Different Fabric spreading

7. Manual Spreading Machines
Operating Procedure:
 Same as Manual Spreader
 Movement along the table and fabric
 Pulling can be controlled by buttons
Advantages:
 Easy to operate
 Low investment
 Suitable for small scale garment industries
Limitations:
 Speed limitation
 Skilled labor required to operate
 Chances of improper selvedge alignment
 Small roll size

8. Semi-Automatic Spreading Machines
Operating Procedure:
 Same as Manual Spreader
 Movement along the table and fabric
 pulling can be controlled by buttons
Advantages:
 Fast and economical
 Proper selvedge alignment
 Ease to operate with electronic clutch
Limitations:
 Fabric roll loading, cutting is still manual
 Not suitable for large scale manufacturing houses
 Small roll size

9. Fully Automatic Spreading Machines
 Automatic loading/unloading device for fabric rolls
 Automatic roll turning arrangement for face to backlay
 Automatic leveling device for fabric edge alignment.
 Automatic cutting device at the end of a run
 Automatic tensioning device to control fabric tension
 Automatic lay height sensing elevator
 Programmable lay length, ply height and step-laying
 Spreading seeds up to 140 m/min

10. Fabric cutting machine
Manual Cutting
( scissors, cutters)
Semi-Automatic
(Round knife cutter,
straight knife, band knife)
Automatic
(CNC, Laser, Plasma, water-jet)

11. Advantages of CNC fabric cutting machine
 Most accurate fabric cutting
 Flexible enough for penetration and movements of knife
 Create a vaccum to hold the fabric firmly and reduce the hieght of the lay
 Ideal for notch making with the required depth
Component of CNC fabric cutting machine
 Bristle bed
 Vaccum system
 Pre-sealer (Polyethylene sheets)
 Perforated paper
 Automatic sharpening of Blades
 CNC programming

12. Sewing machine
Two types of sewing machines (Based on operating system)
 Manually operated sewing machines :
Driven by physical energy.
Used for domestic and tailoring purposes.
Less production, but more laborious.
Low cost.
 Electrically operated or Industrial sewing machines
(Semi-automatic electrical or Computerized sewing
machines):
Usually driven by electric power.
High productivity.
Used in garments industry.
Cost is high.

13. Computerized sewing machines
 Used for very fast and accurate sewing.
 Very expensive and require very efficient operator,
Some examples of mostly used computerized sewing
machines are:
 Computer Controlled Cycle Machine with large Sewing
Area.
 Cylinder Bed Machine with Automatic threads Trimming.
 1-Needle, lock stitch unison feed machine with double
capacity.
 1-Needle, lock stitch portable machine with Automatic
thread Trimmer.
 2-Needle, 2/3/4 thread over lock sewing machine with
built-in rolled hemming and differential feed.
 Automatic Jeans pocket setter with new automatic bobbin
winder/changer.
 3-Needle, plain feed double loop seam machine with
Tractor type presser foot.
 High speed, lockstitch, buttonhole machine.
