The textile industry is an important pillar industry and civilian production industry in our country. my country has become a major textile country in the world, and the total fiber processing volume accounts for more than 40% of the world. With the improvement of people's living standards and quality, the demand for new varieties, differentiated, differentiated and eco-friendly yarns is also increasing. Among them, eco-friendly yarn is not only a requirement for the production process of raw materials, but also a requirement for the spinning process. The innovation of spinning method is the basis for developing new yarn varieties and fabrics.

The strands are characterized by high strength, low hairiness and evenness. Cerro spinning and cable spinning are two types of strand production methods that can be realized on the spinning frame. Among them, Cerro spinning can produce similar double-ply yarns, but the existing cable spinning uses a single roving to feed, and installs and divides it. The rollers complete the division of the whiskers after drafting to form the form of strands. The existing problems are: 1. The width of the whiskers is small, and it is not easy to divide; 2. The splitting rollers are covered with dividing grooves, and the number of strands divided by the whiskers is not large. Stable, it varies between 3-5 strands, which cannot be precisely controlled and affects the uniformity of evenness; the number of fiber strands on long segments will change, which will eventually lead to uneven yarn structure and unstable performance.
