[0003] At present, most of the core-spun yarns on the market are made of ordinary spandex, which has low chemical resistance stability, and is prone to aging after a long time, poor elastic stability, and easy to wrinkle after wearing.
Although there are also core-spun yarns made of polyester spandex double filaments, the dimensional stability of the product is improved, but the skin-friendly comfort is poor, there is static electricity, and it is airtight and deodorant
In addition, the existing core-spun yarn has poor thermal insulation

Embodiment 1
[0022] A multi-variety blended functional core-spun yarn, the core-spun yarn uses PBT filament as the core yarn, and blended fibers are used as the outsourcing fiber of the core-spun yarn, and the blended fibers are viscose, ordinary acrylic fiber, tencel, goat The mixed fiber of velvet, the ratio of the raw materials of the PBT filament and the blended fiber is as follows: 25-29% of PBT filament, 38-42% of viscose fiber, 13-17% of ordinary acrylic fiber , 11-15% Tencel, 4-6% cashmere.
Embodiment 2
[0024] A multi-variety blended functional core-spun yarn, the specification of the PBT filament is 50D, and the ratio of the raw materials in the PBT filament and the blended fiber is as follows: 27% PBT filament, 40% % viscose fiber, 15% ordinary acrylic fiber, 13% tencel, 5% cashmere.
Embodiment 3
[0026] The production process of a kind of multi-variety blended functional core-spun yarn adopting the above-mentioned embodiment 2 comprises the following process steps:
[0027] Step 1, making the mixed fiber into roving, which includes the steps of blending, cleaning, carding, drawing, and roving;
[0028] Step 2, spinning process: use spinning frame, with PBT filament as core yarn, the roving that mixed fiber is made is as core-spun yarn, is made into core-spun yarn;
[0029] Step 3. Winding process: wind the manufactured core-spun yarn into a bobbin on a winder.
[0030] In the cotton blending process, after the raw materials in the blended fibers are evenly mixed according to the proportion, they are packed tightly and pressed into cotton bales, and the cotton bales are closely arranged and placed vertically; Squeeze for a certain period of time so that the water can evenly penetrate into the raw material, set the distance of the beater blade protruding from the rib to...

Abstract
The invention relates to the technical field of spinning, and discloses a multi-variety blended functional covering yarn and a preparation process thereof. PBT filament yarns are used as core yarns ofthe covering yarn, blended fibers are used as outer fibers of the covering yarn, the blended fibers are mixed fibers of viscose fibers, common acrylic fibers, tencel and cashmere, in percentages by weight, the PBT filament yarns account for 25-29% of the raw materials, the viscose fibers account for 38-42% of the raw materials, the common acrylic fibers account for 13-17% of the raw materials, the tencel accounts for 11-15% of the raw materials, and the cashmere accounts for 4-6% of the raw materials. By the multi-variety blended functional covering yarn, the size stability of a fabric is good; the multi-variety blended functional covering yarn has anti-pilling and anti-static properties; the finished product has excellent combination properties of five fibers; the multifunctionality of the product is improved; and attraction of the product to consumers is enhanced favorably.
Description
technical field [0001] The invention relates to the technical field of spinning, in particular to a multi-variety blended functional core-spun yarn and a preparation process thereof. Background technique [0002] Core-spun yarn is also called composite yarn or covered yarn. It is a new type of core-spun yarn composed of two or more fibers. It combines the advantages of outer fiber and core fiber. Make the most of strengths and avoid weaknesses, and the finished yarn has both the excellent characteristics of the outer fiber and the core fiber. [0003] At present, most of the core-spun yarns on the market are made of ordinary spandex, which is not stable in chemical resistance, is prone to aging after a long time, has poor elastic stability, and is easy to wrinkle after wearing. Although there are also core-spun yarns made of polyester spandex double filaments, the dimensional stability of the product is improved, but the skin-fitting comfort is poor, static electricity and ...
