Problems solved by technology

[0002] The rigidity, flexibility and drape of fabrics are important properties that affect the appearance of fabrics, and it is particularly important to accurately test them. The existing fabric rigidity, flexibility and drape tests are carried out separately, that is, one method can only test one property, so The test consumes more fabric samples, and the test workload is relatively large, and the test takes a long time

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] Such as figure 1 As shown, a fabric fixing device used in a method for simultaneously testing fabric rigidity, flexibility and drapability includes a first pin 1, a second pin 2, a third pin 3 and an image pickup device. The image capture device adopts a digital camera with more than 10 million pixels. The first pin 1, the second pin 2, and the third pin 3 are all arranged horizontally and arranged in an isosceles triangle (that is, the projections of the first pin, the second pin, and the third pin on a plane perpendicular to the axis of the first pin are respectively are the three vertices of an isosceles triangle.). The distance between the first pin 1 and the second pin 2 is 6 cm and they are set at the same height. The third pin 3 is located 2 cm below the line connecting the first pin 1 and the second pin 2 , and on the perpendicular line between the line co...

Abstract

The invention discloses a method for simultaneously testing stiffness, flexibility and drapability of a fabric. The method comprises the following steps: step one, tailoring a to-be-tested fabric intoa first rectangular sample and a second rectangular sample, and successively carrying out step two, step three, step four, step five and step six if i equals to 1, 2; step two, placing the ith rectangular sample on a fabric fixing device; step three, photographing the fabric by an image photographing device; step four, acquiring point cloud and a three-dimensional point cloud coordinate array byImageware software; step five, storing the three-dimensional point cloud coordinate array into a data file in an asc formate, and reopening the three-dimensional point cloud coordinate array in Imageware; step six, carrying out image and feature extraction in the Imageware software; and step seven, solving the flexural rigidity E and fabric draping coefficient of the to-be-tested fabric.

Description

technical field [0001] The invention belongs to the technical field of textile and garment performance testing, in particular to a method for simultaneously testing the rigidity, flexibility and drape of fabrics. Background technique [0002] The rigidity, flexibility and drape of fabrics are important properties that affect the appearance of fabrics, and it is particularly important to accurately test them. The existing fabric rigidity, flexibility and drape tests are carried out separately, that is, one method can only test one property, so The test consumes more fabric samples, and the test workload is larger, and the time required for the test is longer. Therefore, it is very important to design a method for simultaneously testing the stiffness, flexibility and drape of fabrics. Contents of the invention [0003] The object of the present invention is to provide a method for simultaneously testing the rigidity, flexibility and drapability of fabrics [0004] The fabr...
