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 incre
