Study on Conventional Method of Test and Evaluation of Woven Fabric's Elasticity on Wrinkle Resistance

Abstract

The traditional woven fabric's shortage of the method of test and evaluation was introduced, and the improvement programs were proposed by experiment. The influence of the objective errors of sample cutting, the inconsistency of the directions of cutting and fabric, the difference of the opposite sides on the test and evaluation was also analyzed. The improvement programs including increasing the sample number and expanding the evaluation index were drawn up and testified by being compared with the actual result. The experiment result confirmed that the veracity of the test result could be improved by cutting accurately and increasing the sample number. It was more reasonable to choose the sum of warp, broad and diagonal crease recovery angles as the assessment index for the woven fabric's elasticity on the wrinkle resistance. For the fabric which has different organization on both sides, the elasticity on the wrinkle resistance of the both sides should be tested separately.
