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 But when the heat & pressure is being withdrawn, the shape may change.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:
minimum time of relaxation is twelve (12) hours.
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 hours making unroll in cutting section. Others 12 hours.
- Relaxation date and time must be recorded. After spreading, will relax 2 hours before cut.
