Embodiment Construction

[0028] The technical solutions of the present invention will be further described below through examples and in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the test device for twisting flatness of fabric after washing includes a fabric twisting simulation device and an image capture device. The fabric twisting simulation device comprises a first baffle 1, a second baffle 2, a bottom plate 3, a stick 7, a moving cylinder 8, a static cylinder, a positioning pin 9 and a positioning ring 10; the first baffle 1, the second Both the baffle plate 2 and the bottom plate 3 are made of metal. The first baffle and the second baffle are fixed at both ends of the bottom plate. A water outlet 4 is provided at the bottom of the first baffle, and a groove 5 is provided on the upper surface of the bottom plate, and the groove 5 communicates with the water outlet. The center position of the second baffle is provided with a round hole 6; one end of the stic...

Abstract

The invention discloses a method for testing the twisted flatness of fabrics after washing. The existing method for detecting the flatness of fabrics after washing does not consider the detection of flatness of hand washing and wringing. The stick body of the device of the present invention passes through the second baffle and is threadedly connected with the moving cylinder; the moving cylinder is provided with a positioning ring and two symmetrical positioning pins; the inner side of the first baffle is fixed to the static cylinder; the static cylinder is provided with a positioning ring and two positioning pins that are symmetrical up and down. The method for testing the flatness of fabric twisting in the present invention: after the fabric is ironed, it is cut and soaked in a mixture of water and detergent, and after taking it out, it is fixed in a fabric twisting simulation device and twisted; it is unfolded and hung to dry; the fabric wrinkle image is collected In the most serious area of ​​arching, the pixel points are filtered and transformed, and the total entropy of the image in the six filtering directions of each sample is obtained; flatness index. In the invention, the flatness test is carried out on the simulated twisted fabric after washing to obtain the evaluation index of the flatness of the fabric.

Description

technical field [0001] The invention belongs to the field of textile and garment performance testing, in particular to a method for testing the twisted flatness of fabrics after washing. Background technique [0002] When washing, especially in the way of water washing, the intervention of water molecules and the action of external forces will have a comprehensive effect on textile materials, causing deformation of the fabric and greatly affecting the flatness of the garment. Therefore, it is of great significance to objectively test and evaluate the flatness of fabrics after washing. On the one hand, the test results can be used to predict the degree of flatness of garments after washing, and it can also help to select suitable clothing categories for fabrics and avoid material selection. Inappropriate waste. [0003] As we all know, water washing can be divided into organic washing and hand washing. The existing method for testing the flatness of fabrics after washing is...
