Problems solved by technology

The breaking strength of 0.8dtex (9.8μm) ultra-fine polyester (which has not yet been mass-produced and sold in the market, spinning is difficult, and there are no manufacturers to produce yarn) is about 50% lower than that of traditional polyester. , the specific surface area increases by about 40%, and it is easy to entangle and entangle with each other during the spinning process, and the friction between the fibers increases, which leads to the inability to draw during the spinning process, so that it is easy to form hair particles, and it is easy to produce coarse details and cause Poor evenness, which affects yarn quality
Due to the high difficulty of spinning, the need for technical research and many other problems, the production difficulty is high, which limits its actual application.

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] There are two types of needle plates in traditional fine needle carding machines, one is chain carding and the other is screw carding. The fibers are combed in a fast piercing and inserting way. This carding method can play a good and effective carding effect on traditional wool and other natural fibers with high moisture regain and is not easy to generate static electricity. When repeatedly piercing the fiber layer, due to the repeated friction effect between the metal needle surface of the needle plate and ...

Abstract

The invention discloses a spinning production process of a super-fine polyester blended yarn. The spinning production process includes the steps: (1) mixed sliver carding: carding mixed slicers of super-fine polyester fibers by a drawing frame with two transformation needle loops after a sliver mixing machine; (2) recombing: performing transformation by a wool type combing machine, performing combing by a card wire and spiral method, and increasing the density of last three rows of a circular comb to 25 specifications by double top comb structures; (3) combination: mixing the fibers by a drawing frame with two transformation needle loops; (4) twistless roving: adopting a twistless wool type roving machine; (5) twisted roving; (6) spinning. By the mode, the spinning production process of the super-fine polyester blended yarn is particularly designed according to properties such as various characteristics and internal indicators of 0.8dtex super-fine polyester fibers, improved equipmentand parameters are adopted, production effects are good, the process tends to be mature and stable, generation of card neps and twitty yarns is decreased, and yarn quality is good.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a worsted production process of superfine polyester blended yarn. Background technique [0002] With the rapid development of the economy and the progress of society, people in contemporary society have further improved their requirements for clothing, and they are more advocating differentiation, diversity, high-end and natural. Traditional chemical fibers can no longer meet people's growing wearing needs, and superfine polyester, as a differentiated fiber in chemical fibers, has received widespread attention in recent years. Yarns spun from superfine polyester are breathable, comfortable, and highly elastic. and wear-resistant properties. [0003] The fabric of superfine polyester fiber can have the characteristics of cashmere, silk and cotton fabrics, and also has many advantages such as soft hand feeling, comfortable wearing and rich luster. The breaking strength of 0.8dte...
