Cutting section is one of the most important sections for manufacturing garments in Garments Factory. To fabric cut out pattern pieces of garment components as per exact dimension of the patterns from a fabric lay is called fabric cutting. It is totally different from general cutting in which exact dimension is not taken into account. The term fabric cutting is only applicable for garments manufacturing technology.
Requirements of Fabric Cutting: The following points must be fulfilled in fabric cutting:
Precision of fabric cutting: Fabric
cutting should be done accurately as per exact dimension of the pattern
pieces in the marker. Accurate cutting depends on methods of cutting
and marker planning. If manual cutting method is used, then cutting
accuracy depends on sharpness of knife, skill of operator, and
attentiveness of operator. Computer controlled cutting and die cutting
have their self cutting accuracy.
Consistent cutting: Whatever be the cutting method used for
fabric lay cutting, it should be ensured that the shape of the cut
components from top to bottom lay are of exact size and shape, otherwise
the garments produced will be defective.
Infused edge:
During fabric cutting, the friction between the fabric and the blade
produces temperature in the blade; the temperature may be up to 3000C.
If the fabric contains synthetic fibers e.g. nylon, polyester, acrylic
or their blends, then fused edge may result in the fabric. Because most
of those fibers melt at around 2500C. Therefore, sticking of cut edge of
fabric will increase the fabric wastage. Moreover, the fused edge after
cooling will form hard bid, which will be a problem of irritation
during use of garments.
To avoid the problem of fused edge formation, the following steps may betaken:
- Reduce the height of the lay - Reduce the cutting speed
- Use anti-fusion paper in the lay at regular interval
- Lubricate the knife during cutting
- Use anti-fusion paper in the lay at regular interval
- Lubricate the knife during cutting
Supporting 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.
