Large-density cotton yarn spinning technology

Abstract

The invention discloses a large-density cotton yarn spinning technology comprising the working procedures of blowing, carding, drawing, roving and spinning. According to the technical scheme adopted for solving the technical problems, in the roving working procedure, the twist degree of technology gears arranged on a roving machine is improved, the tooth number of the roving twist degree technology gear Z1 is decreased, and the tooth number of the roving twist degree technology gear Z2 is increased; meanwhile, the winding density of the roving machine is increased, the tooth number of the winding technology gear Z10 is decreased, and the tooth number of the winding technology gear Z11 is increased. The twist degree of the technology gears in the roving working procedure during ring spinning is creatively improved, meanwhile, the winding density of the roving machine is improved, so that yarns with the twist degree matched with that of the yarns in the spinning working procedure are spun on the roving machine in the roving working procedure, and the yarns have the large density larger than 194 tex.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to a textile process of large linear density cotton yarn. Background technique

[0002] Ring spinning is the most widely used and most common spinning method in the market. The sliver or roving fiber sliver after drafting is introduced by the ring traveler. The bobbin winding speed is faster than the traveler, and the cotton yarn is twisted. It is made into spun yarn. It is widely used in the spinning engineering of various short fibers. Such as carding, combing and blending. The rotation speed is slightly smaller than that of the bobbin to get winding. The spinning speed is high, and the shape of the ring-spun yarn is a conical helix in which the fibers are mostly transferred from the inside to the outside, so that the fibers are wound and connected inside and outside the yarn. The structure of the yarn is compact and the strength is high. It is suitable for thread making, weavin...
