常用产品标准中扭曲率试验方法比较

摘要

织物、服装上衣摆缝或裤（裙）侧缝在制造时可能会出现扭曲（又称扭斜），同时在洗涤后经常会出现扭曲，轻者影响美观，重者影响服用性能，因此对于织物、成衣产品考核水洗后扭曲率（又称扭斜率）指标是非常必要的。产品标准中洗后扭曲通常使用各自测试方法进行测试，因此不同的产品标准中扭曲的测试方法不尽相同，本文主要总结了常用产品标准中洗后扭曲测试方法。%During manufacturing or after laundering, fabrics, side seam of upper garments or pants (skirts) may appear distortion (also called spirality), which affect beautiful outlook, and even affect wearability. So for fabrics and garment products, inspection distortion ratio (also called spirality ratio) after laundering is very necessary. Different standards have different methods for distortion testing. This article mainly summarized the commonly used test methods for distortion after laundering.
