Embodiment 1

[0018] A kind of preparation technology of soft swelling type polyester wool blended yarn, comprises the following steps:

[0019] 1) Available in Untreated Merino Wool, Total Easy Care Merino Wool, Black Polyester and Black Stretch Polyester. Untreated wool measures 18.4mic, Total Easy Care wool measures 20.3mic, black polyester 2.2dtex and black stretch polyester 2.2dtex;

[0020] 2) Wool and polyester are mixed many times, combed and combed to make the fibers fully mixed and even, and the yarn is evenly dry;

[0021] 3) Roving: the sliver combed by the needle is further stretched to make a thinner sliver;

[0022] 4) Spinning: According to the predetermined yarn count, the roving sliver is twisted into a semi-finished yarn by distraction, and the spinning speed is 8500rpm;

[0023] 5) Winding: The semi-finished yarn is set by winding, cutting off harmful hairiness, foreign fibers and coarse details;

[0024] 6) Waxing: Wax the finished yarn to reduce hairiness and improv...

Abstract

The invention provides a preparation process of a soft-expansion elastic polyester wool blended yarn. The preparation process comprises the following steps of 1) selecting untreated merino wool, completely easy-care merino wool, black polyester and black elastic polyester, wherein the size of the untreated wool is 18.4-22.5 mic, the size of the completely easy-care wool is 20.3-22.5 mic, and the size of the black polyester is 2.2dtex and the size of the black elastic polyester is 2.2dtex; 2) enabling the wool and polyester to be subjected to sliver mixing for multiple times, so that the fibersare fully and uniformly mixed through combing and gilling, and yarn levelness is uniform; 3) performing roving; 4) performing spinning: according to a preset yarn count, enabling rough yarn slivers to be drawn and twisted into semi-finished yarns; 5) performing spooling; 6) performing waxing: waxing the finished yarns to reduce hairiness and improve the weavability of the yarns; and 7) performingpackaging: packaging and boxing the yarns. Untreated and completely easy-care wool is selected and matched with black polyester and black elastic polyester, so that the yarn is soft, fluffy, high inrebound resilience, excellent in fabric drapability, bright in color, environmentally friendly, economical and efficient.

Description

technical field [0001] The invention relates to the field of blended spinning, in particular to a preparation process for soft and elastic polyester-wool blended yarn. Background technique [0002] Due to the hard hand feeling of ordinary polyester, general touch, high static electricity generated by friction, poor air permeability and hygroscopicity, people have gradually studied the improvement and modification of ordinary polyester to obtain new functions to make up for its shortcomings. Among the modified polyesters, elastic polyester (PTT) has a wide range of adaptability. PTT is suitable for pure spinning or compounding with cellulose fibers, natural fibers, and synthetic fibers to produce carpets, casual clothes, fashion, underwear, sportswear, swimwear and socks. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a preparation process for soft and ...
