Fabric Relaxation: When
the fabric comes from the dying & finishing, the fabric remains a
slightly hot. In dryer, compactor heat is applied on fabric. So moisture
is remove from the fabric & it is not in actual condition. But if
we keep the fabric in normal temperature & pressure for a certain
time, the fabric absorbs moisture from the atmosphere & regain its
original nature. This process is called fabric relaxation. Another cause
of fabric relaxation is to maintain the dimensional stability of
produced garments. When the fabric is being processed in different
finishing machines, it goes under certain heat & pressure to give it
proper shape. But when the heat & pressure is being withdrawn, the
shape may change. So, if the dimension is became stabilized before
cutting, no chance to strain in garments.so relaxation is very necessary
before cutting.
Relaxation period: Fabric
relaxation is performed for a certain period. This time is varied from
fabric to fabric. But the minimum time of relaxation is twelve (12)
hours. This time also may vary according to the buyer’s recommendation.
After fabric relaxation, different tests are performed for maintaining
the proper quality.
- Spandex fabrics will be relaxed minimum 24 hour making unroll in cutting section. Others 12hour.
- Relaxation date and time must be recorded. After spreading, will relax 2 hours before cut.
