Description

technical field [0001] The invention relates to a silver fiber detection device, in particular to a silver fiber scratch resistance evaluation device. Background technique [0002] With the continuous improvement of modern living standards, people's requirements for the quality of life are also constantly improving. Clothing, food, housing, and clothing are the first. Fibers are already a variety of clothing that people usually wear. For example, on the surface of nylon fibers The silver fiber obtained by coating the silver layer, the anti-electromagnetic shielding fabric made of silver fiber has been widely used in radiation-proof clothing for pregnant women because of its excellent radiation-proof performance. As we all know, the electromagnetic shielding principle of radiation-proof clothing mainly depends on In the closed loop formed by silver-plated fibers, the conductivity will directly affect the performance of electromagnetic shielding, and the thickness of the silve...

AI Technical Summary

Problems solved by technology

[0023] The above-mentioned method and equipment can only measure the number of fiber fracture failures, but cannot simulate the real friction mode between the fiber and the crochet needle during the weaving process, and for the silver-plated fiber, it is not possible to measure the friction between the silver layer and the crochet needle by breaking. The resistance value changes each time when the crochet hook scratches, and the amount of silver plating on the silver layer cannot be controlled in advance to obtain the expected electromagnetic shielding effect of the final finished fabric.
