Colored polyesters and viscose blended siro-and-compact spinning yarns and manufacturing process

Abstract

The invention relates to colored polyesters and viscose blended siro-and-compact spinning yarns. Thick yarns spun by black flat polyesters, black triangular polyesters and blue triangular polyesters are fed on a siro-and-compact spinning machine together with equal-quantitative thick yarns spun by white viscose fibers through two thick yarns in order to form gray siro-and-compact spinning yarns. The number of blended siro-and-compact yarns is 20 to 60. A manufacturing process comprises following steps of a blowing process, a combing process, a drawing process, a roving process, a spinning process and a rewinding process. As for the spinning machine, the number of roving suspended spindles and siro-spinning bell mouths is doubled and a compact spinning device is added. The colors of spinning steel wire rings are darken by 1 to 2 degrees. Double bell mouths and a large-power fan are adopted in the region behind the spinning machine. The relative humidity of production environment in all processes is within the range of 52% to 58%.The colored polyesters and viscose blended siro-and-compact spinning yarns are compact in structure, few in features and defects and high in yarn strength and are energy-efficient and eco-friendly without dyeing.

Description

technical field [0001] The invention relates to textile products, in particular to a colored polyester and viscose blended siro compact spinning yarn and a manufacturing process thereof. Background technique [0002] With the continuous development of spinning technology and consumers' pursuit of personalized, fashionable and diversified fabrics, the traditional single-structure spinning mode can no longer meet market demand. At present, there are many compact spinning or siro spinning products on the market, but they are not as good as siro compact spinning with less hairiness, high quality, and good cloth style, and the general siro compact spinning is made of two rovings of the same raw material It is woven and does not have the two-color three-dimensional effect of blended siro compact yarn. The production practice proves that the blended siro compact spun yarn produced by making two rovings of colored polyester and viscose has the characteristics of less hairiness, les...

Problems solved by technology

[0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a colored polyester and viscose blended siro compact spinning yarn and its manufacturing process to solve the problem of difficult mixing of colored polyester fibers, serious electrostatic phenomena, easy slipping, and difficult control. The product has a lot of hairiness, and the problem of many color grains and defects on the cloth surface
