Sorona/wool semi-worsted spinning yarn as well as manufacturing process thereof and application thereof

Abstract

The invention relates to the textile field, in particular to a sorona / wool semi-worsted spinning yarn as well as a manufacturing process thereof and an application thereof. The invention provides the yarn; and the key technical point is as follows: the yarn is a three-stranded knitted yarn with count of 36 N / 3, which is obtained through spinning 70% of wools and 30% of sorona fiber by weight. The invention further provides the manufacturing process of the sorona / wool semi-worsted spinning yarn; and the process comprises the following steps of dyeing, blending, cotton carding, drawing of three strands, rough yarn forming, spun yarn forming, spooling and doubling. The invention further provides a sweater using the sorona / wool semi-worsted spinning yarn. According to the invention, an environment-friendly sorona fiber with a certain ratio is adopted for the knitted sweater, so that the finished product sweater has the advantages of soft and rich handle, vivid color, good moisture absorbing property, good air permeability and excellent heat retention property; and compared with the traditional sweater product, the sweater has the advantages of better water washing size stability and machine washability.

Description

technical field [0001] The invention relates to the field of textiles, in particular to semi-worsted yarns of sorona / wool and its production process and application. Background technique [0002] With the improvement of people's living standards, the requirements for textiles are also getting higher and higher. The requirements for textiles include not only their own performance, but also the environmental protection of their raw materials. [0003] Sorona fiber is the latest advanced polymer platform launched by DuPont in the United States in its continuous innovation of fiber raw materials for more than 60 years. It is composed of 1,3-propanediol (PDO) and purified terephthalic acid (PTA). Made from raw materials. Among them, PDO is its key raw material, accounting for 37% of the total raw materials. Since DuPont has now successfully prepared the PDO required for the production of Sorona polymers by obtaining glucose from corn and then fermenting it, 37% of the raw mate...
