Description

technical field [0001] The invention relates to a rubber-plastic and multi-walled carbon nanotube composite elastic matrix and a preparation method thereof, in particular to a core method for modifying and optimizing the main material of textile aprons and improving quality, and belongs to the technical field of formula design of spinning aprons. Background technique [0002] At present, new textile fibers are showing a high-speed development trend of diversification and diversity. The main reason is that the shape, performance or other aspects of the fibers are different from the original traditional fibers. The new fibers can be divided into new natural fibers, new cellulose fibers, soybean protein fibers, and water-soluble fibers. Sexual fiber, functional fiber, differential fiber, high-performance fiber and high-sensitivity fiber series.

AI Technical Summary

Problems solved by technology

[0003] The ultra-fine denier fiber, high-modulus conductive metal fiber and other processing aids in the new textile fiber series have corresponding special performance requirements for the spinning apron drafting process, and the ultra-fine denier fiber is extremely susceptible to static electricity and adhesion. The effect of adhesion is freed from the fiber bundle, which makes the surface of the apron stick to "flowers" and causes frequent yarn defects; the high modulus conductive metal blended fiber has a large modulus and poor hand feeling, and it wears the surface of the draft apron severely. The yarn guide movement is easy to be concave and even cracked, which greatly shortens the service life of the spinning apron; various spinning processing aids are prone to migration and adhesion to the surface of the swollen apron, and the continuous increase of the surface of the apron can produce sticky bands. "Causes an increase in end breaks and frequent yarn defects, and at the same time causes the apron to run viscously and stutter to generate mechanical waves

At present, new textile fibers mainly adopt modern high-efficiency spinning technology. The spinning forms are compact spinning (compact spinning) and siro spinning. The spinning apron designed and manufactured by the ordinary rubber-plastic system is prone to entrainment "pied" caused by static electricity and adhesion during the spinning and drafting process, and the high shear force causes the inner and outer surfaces of the yarn guide to tear, Unfavorable phenomena such as concave wear and tear, resulting in a substantial increase in loss, a significant decline in the stability of spinning quality, and increased difficulty in maintenance
