氨纶经平绒弹性织物最佳氨纶用量的确定

Determination of the Best Spandex Consumption in Spandex Locknit Elastic Fabric

通过对锦纶／氨纶交织经平绒弹性织物的弹性伸长率及弹性回复率的测试，求出相应的回归直线方程，计算出最佳弹性状态下氨纶用量的理论值为２０％ ．为降低成本，在满足弹性的要求下，氨纶的用量为１８％ ，以此指导实际生产．

For determining elastic extension and recovery percentage of locknit elastic fabric, which is mixed with nylon and spandex, the correspondent regression straight line equation was established, and the theoretical spandex content could be up to 20%. While meeting the requirement of elasticity, spandex content can be reduced to 18% to decrease the cost, which will lead to a better practical production.
