Production device and production method for soft, clean and pure yarn

Abstract

The invention provides a production device and a production method for soft, clean and pure yarns. An upper rubber roll in each drawing roller pair is connected with a pressurizing assembly through aconnecting vertical rod which can be stretched or shortened, so as to realize pressure adjustment between the upper rubber roll and a lower roller in a spinning process through stretching or shortening control of the connecting vertical rod, and thus pressure adjustment of fiber strands between the upper rubber roll and the lower roller in a spinning process is realized. Thus, selection of fiberswhich can slide mutually in the fiber strands is realized. Therefore, on one hand, gradual change control of yarn density of spun yarns is realized, and on the other hand, through controlling differences of yarn density in the fiber strands, a process of few fibers in low yarn density wrapping multi-fibers in high yarn density in a twisting and yarn forming process is realized, so that integratedstructure control of inner-loose and outer-tight of yarns is realized, and development of yarns which are smooth and clean on surfaces and soft is realized.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a soft and pure spinning production device and production method. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements are put forward for the development of textile raw materials and textile technology. Among them, high-quality, high-performance textiles and clean production and processing have become the main development direction of the modern textile industry and an effective way to improve product grades and added value. With the improvement of modern living standards and the acceleration of the pace of work, the high shape retention and easy care of textiles have become important attributes and distinctive symbols of high-quality fabrics and cl...

Problems solved by technology

At the same time, in the current spinning process, the rotation of the rollers is used to drive the rubber rollers that are in close contact with them to rotate, and then the roving is pressed and fed between the rollers and the rubber rollers, thereby realizing the drafting process of the rovings. However, this kind of drafting mainly depends on adding external equipment to control the fibers in the roving. Since the fibers are flexible and soft materials with elasticity, the external rigid equipment cannot control the fibers very well, especially is when the twist coefficient of the fed roving is large
