Embodiment 1

[0028] Embodiment 1: 16sCD (40D nylon / 34F+40D)+70D yarn

[0029] In the spinning process of the three-core yarn in this example, the raw materials are elastic yarn (filament), non-elastic yarn (filament) and staple fiber, elastic yarn: non-elastic yarn: staple fiber (addition amount) = 2:1: 7. The elastic yarn is made of spandex, of which spandex consists of two parts, half of which is 40D, and the other half is 70D; the non-elastic yarn is nylon filament, which is 40D; the staple fiber is cotton fiber, which is 1.6D. The specific process is as follows:

[0030] (1) Opening and cleaning process:

[0031] The cotton opening and cleaning process is sequentially as follows: cotton grabbing machine → pre-cleaning machine → multi-bin cotton mixing machine → fine cleaning machine → cotton condenser, the raw materials are gently opened with dust sticks to remove foreign particles, broken fibers and dust, and use multiple The silo makes the raw materials fed at the same time output ...

Embodiment 2

[0051] Embodiment 2: 16S polyester (50D polyester+40D)+70D yarn

[0052] In this embodiment, the raw materials are elastic filaments (long filaments), non-elastic filaments (long filaments) and staple fibers, elastic filaments: non-elastic filaments: staple fibers (addition amount) = 1:1:7, elastic filaments are selected from spandex, Among them, spandex includes two parts, half of which is 40D, and the other half is 70D; the non-elastic yarn is polyester, and the fiber is 50D; the short fiber is polyester, and the fiber is 1.5D. During the spinning process, the spindle speed of the spinning machine is 13000r / min, the speed of the winder is 1000r / min, and all the other process designs are identical to embodiment 1.

[0053] The bobbin yarn formed by the above process, that is, the three-core yarn is 16S polyester (50D polyester+40D)+70D yarn, and the three-core yarn is used as the weft yarn. The fabric weave of the gray fabric is 76x48, and the warp yarn is 16S polyester.

Embodiment 3

[0063] Embodiment 3: 16S cotton viscose (40D nylon+40D)+7D yarn

[0064] In this example, the raw materials are elastic yarn (long yarn), non-elastic yarn (long yarn) and staple fiber, elastic yarn: non-elastic yarn: staple fiber (addition amount) = 2:1:7, elastic yarn is spandex, Among them, spandex includes two parts, half of which is 40D, and the other half is 70D; the non-elastic yarn is polyester, and the fiber is 40D; the short fiber is viscose blended fiber, and the fiber is 1.5D. Be 13000r / min, the speed of a vehicle of winder is 1200r / min, and all the other technological designs are identical with embodiment 1.

[0065] The bobbin yarn formed by the above process, that is, the three-core yarn is 16S cotton viscose (40D nylon + 40D) + 7D yarn, and the three-core yarn is used as the weft yarn. The gray fabric weave is 155x55, and the warp yarn is 40s cotton.

[0066] After the woven fabric has passed through drawing, sizing, drafting, weaving, and after dyeing and fini...

Abstract

The invention relates to spinning processes of cotton and chemical fiber purely-spun or blended yarns, particularly to a three-core yarn spinning device and process. The process takes inelastic filaments, elastic filaments and staple fiber as the raw materials, wherein the staple fiber is processed through opening and cleaning, carding, drawing and roving, the elastic filaments are divided into two parts, parts of the elastic filaments and parts of the inelastic filaments compose network yarns, and the remaining elastic filaments are drawn into drawn yarns; the network yarns are guided onto the rollers of a spinning machine under the action of tension force to be converged with the staple fiber and the elastic filaments, so that the network yarns and the drawn yarns pack and pierce the staple fiber to form bobbin yarns, and the bobbin yarns are formed into three-core yarns after being twisted by a winding machine. By means of the technical scheme of the three-core yarn spinning process, the three-core yarns with high elasticity, high rebound elasticity and attractive fabric appearance can be obtained.

Description

technical field [0001] The invention relates to the spinning process of cotton and chemical fiber pure spinning and blended yarn, in particular to a spinning device and method of three-core yarn. Background technique [0002] With the continuous improvement of people's living standards, clothing fabrics have already broken through the original functions of keeping warm and covering. People pay more attention to the diversified development of comfort, health and self-expression in clothing; methods such as multi-component blending, interweaving, core-spun and covering of natural fibers and chemical fibers are widely used. Good durability and shape retention, and comfortable wearing have been recognized by the market. However, in the case of high elasticity, the resilience is often insufficient, and the clothes are easily deformed after repeated wearing. Therefore, the current market needs a super-elastic fabric with high elasticity, better resilience, and a beautiful fabric...
