Description

Technical Field

[0001] The utility model relates to cashmere fiber processing equipment, in particular to a cashmere fiber plasma surface modification processing device. Background Art

[0002] The surface modification of cashmere fibers using low-temperature plasma treatment technology can etch the cashmere fiber scales, reduce the directional friction effect and fabric shrinkage, improve the felting of the cashmere fibers, and significantly improve the hydrophilicity and dye uptake. At present, the existing low-temperature plasma treatment process for cashmere fibers is to first clean and remove impurities from the cashmere fibers, then transfer them to a drying device to dry the cashmere fibers, and then place the dried cashmere fibers into a low-temperature plasma treatment device for treatment. There are many transfer links in the middle, resulting in low overall processing efficiency. Therefore, it is urgent to develop a device that can improve processing efficiency to meet actual usage needs. Utility Model Content
