Embodiment 1～4

[0057] Select elastic knitted fabric samples 1, 2, 3, and 4 of the same specification and different batches as test objects. The fabric specification: synthetic fiber warp-knitted elastic mesh knitted fabric with a spandex fineness of 70D and a spandex content of 17.4%.

[0058] (1) Preparation of elastic fabric test sample: a rectangular cloth sample of length × width = 350mm × 100mm, the effective length between the two clamps is 125mm, the long side of the sample is parallel to the direction of the elastic yarn, and each sample is Fold and cut the long side from the center, and sew it with four-point herringbone stitches. The stitch density is 5 mountains / 3cm, and the height of the seams is 5mm;

[0059] (2) Set the measurement parameters of the test instrument: adjust the stretching distance l of the reciprocating gripper 1 200mm, the initial elongation rate is 60%, and the reciprocating stretching rate is 65%, 59%, 70%, and 70% respectively;

[0060] (3) sample loading a...

Abstract

The invention relates to an elastic fabric fatigue testing method, which is characterized in that: a testing sample is stitched with a four-point herringbone trace pattern, and an elastic yarn extracting test is carried out; the testing method is a tensile fatigue testing method with a primary elongation; the testing apparatus used in the testing method is an elastic fabric fatigue testing apparatus. The testing method provided by the invention comprises steps of sample preparing, parameter configuring, sample adjusting, fatigue testing, fatigue evaluating, and the like. The testing method provided by the invention is fast, accurate, and is easy to operate. In prior arts, no problem is shown in elastic fabric fatigue tests and extracting tests. However, problems occur during actual wearing, and consumers are unsatisfied. With the method provided by the invention, the phenomenon can be effectively avoided, such that economic loss of most enterprises due to the reason can be recovered.

Description

technical field [0001] The invention relates to a method for testing the performance of textiles, more specifically, a method for testing the fatigue of textiles. Background technique [0002] In the actual wearing process of elastic knitted underwear, sometimes there will be different degrees of fatigue and the phenomenon of spandex yarn pulling out in the seam, resulting in broken ends of spandex yarn on the fabric surface, and uneven blistering on the fabric surface, which affects the appearance and fashion of the product and taking performance. Therefore, it is very necessary to test and analyze the fatigue and pull-out of spandex elastic knitted fabrics, but sometimes there is no problem with the test results of fatigue and pull-out of elastic knitted fabrics, but there are problems in the actual wearing of elastic underwear, causing customers Dissatisfaction and other phenomena have brought certain economic losses to the enterprise. The reason for this situation is t...
