Method for simultaneously testing bending creep of multiple samples in two directions of garment fabric

Abstract

The invention discloses a method for simultaneously testing bending creep of multiple samples in two directions of a garment fabric. The bending creep property of the fabric cannot be obtained by theexisting bending property detection method. The method comprises the following steps of 1, cutting a tested fabric into a tested sample; 2, placing the tested sample in place, and shooting; 3, after starting shooting, enabling each test narrow band of two tassel parts of the tested sample to naturally droop under the action of gravity; 4, after shooting is finished, intercepting a frame of image picture before drooping and a frame of image picture after drooping of the tested sample as a tiled image and a droop image respectively, and detecting areas of 2n test strips in the tiled image and areas of 2n test strips in the droop image respectively; 5, calculating bending indexes of the n test narrow bands of the two tassel parts on the tested sample; 6, calculating the comprehensive bendability of the tested sample; and 7, intercepting a plurality of images in the shot video by taking a preset duration as a time interval, and respectively testing to obtain a bending creep curve.

Description

technical field [0001] The invention belongs to the technical field of textile and garment performance testing, and in particular relates to a method for simultaneously testing the bending creep of multiple samples in two directions of a garment fabric. Background technique [0002] Flexibility of fabrics, also known as rigidity and flexibility, is an important indicator to reflect the style of fabrics. For example, fabrics for suits require crispness and good shape retention; fabrics for underwear require soft touch and comfortable wearing; fabrics for summer women's clothing require elegant and soft. Therefore, it is usually necessary to test the flexibility of the fabric before making clothes, so that suitable clothes can be selected according to the test results. There are many methods for measuring bending, among which the most basic and commonly used method is the inclined plane method, and now it is also commonly used for measuring with a fabric style meter. However,...

AI Technical Summary

Problems solved by technology

However, whether it is the inclined plane method or the fabric style meter test method, there is a common defect: only one direction of the fabric can be tested each time. As we all know, in order to avoid accidental errors in scientific experiments, multiple measurements are required.

Obviously, this method cannot obtain the flexural creep properties of the fabric
