1. Precision of cut- It depends on :
- Methods of cutting employed.
- Marker planning- distance between two pattern pieces.
- Marker marking- correct marking by pen/pencil.
- Condition of cutting equipment- machine, blade etc.
- Skill and motivation of the operator.
2. Clean edge- Free from fraying.
3. Unfused edge- High temperature produced during cutting can fuse fabric edges by melting. Unfused edges can be ensured by taking the following measures:
- Well sharpened blade.
- Use of anti-fusion (heat absorbent) paper.
- Spraying silicone lubricants on the blade.
- Less cutting speed.
- Reducing the height of the lay.
4. Support of the lay- using a polyethylene sheet or nylon bristle under the bottom ply
5. Consistent cutting- all plies should be of same dimension
2) Computerized Technique
- Knife cutter
- Laser cutter
- Water jet
- Plasma jet
Choice of Cutting Technique:
1. Availability of cutting machines.
2. Number of plies or spread height- band knife for upto 6″ height, straight knife for higher height.
3. Type of garment parts- straight knife & knife cutter for bigger parts, band knife for sharp corner, die cutter for small parts like pockets.
4. Type of fibre in the fabric- laser cutter should not be used for thermoplastic fibres, water jet is suitable for low absorbency fibres like polyester.
5. Cutting speed required- computerized method for higher speed.
6. Quality of cutting- computerized techniques for high quality cutting.
7. Volume of production- straight knife & computerized techniques for higher volume
8. Cost of cutting.
