Embodiment 1

[0049] Take the production of 19.7tex tencel / linen vortex spinning elastic core-spun yarn on the MVS861 vortex spinning machine equipped with a filament feeding device as an example. The core-spun yarn is composed of the central T400 composite elastic filament and the outer short fiber. The outsourcing short fiber is composed of tencel and flax in a mass percentage of 7:3, the mass ratio of outsourcing fiber to T400 composite elastic filament is 5:1, and the final product needs to be dyed black.

[0050] The specific production plan is as follows: pretreat the flax fiber to improve its spinnability; pass the flax fiber and tencel fiber through the opening and cleaning process and the carding process to make a mixed raw sliver; The mixed cooked sliver is produced by three drawing processes; the mixed cooked sliver is fed into the air-jet vortex spinning machine, and the T400 filament is fed from the front roller through the wire guide device to make a tencel / flax vortex spinning...

Abstract

The invention relates to a tencel / flax vortex spinning elastic core-spun yarn and a preparation method thereof. The core-spun yarn is composed of a central T400 composite elastic filament and an outer wrapping fiber, wherein the outer wrapping fiber is composed of tencel and flax. The prepared tencel / flax vortex spinning elastic core-spun yarn and a subsequent fabric are overhung, elegant, moisture-absorbing, breathable, smooth in silk quality, antibacterial, mildew-proof, green and environment-friendly, and the core-spun yarn integrates the advantages of the elastic core yarn and is comfortable to wear and good in shape retention; and compared with a traditional flax blended product, the problem that the dyeing degree of flax fibers is lighter than that of tencel fibers after dyeing, and the problem that the blending ratio of the flax fibers of a final product is reduced can be remarkably solved.

Description

technical field [0001] The invention belongs to the field of core-spun yarn and its preparation, in particular to a tencel / flax vortex-spun elastic core-spun yarn and a preparation method thereof. Background technique [0002] Air-jet vortex spinning is the latest spinning technology in the current spinning system. Since 2005, a small number of domestic enterprises have introduced air-jet vortex spinning equipment and achieved good economic benefits. Air-jet vortex spinning is directly wound into bobbins by sliver spinning, and the spinning process is short; the spinning speed is extremely high, which is 15-20 times that of ring spinning; the equipment is highly automated and reduces labor. [0003] Tencel is a new type of regenerated cellulose fiber produced by solvent spinning using sustainable wood as raw material. Compared with natural textile raw materials, Tencel has more technological innovation significance and better fashion value. Its fabric has the comfort of cot...
