Pretreatment method of viscose fibers and processing method of terylene-viscose blended knitting yarn

Abstract

The invention provides a pretreatment method of viscose fibers, which comprises the following steps: (a) spreading a layer of viscose fibers, and spraying a water and crude oil mixer of 30-50 DEG C; (b) packing the viscose fibers, and stacking in a storehouse without ventilation; (c) and opening the viscose fibers to dry in the air. The invention also provides a processing method of terylene-viscose blended knitting yarn, which comprises the following steps: pretreating viscose fibers, opening and cleaning the cotton, combing the cotton, making ribbons, spinning coarse yarn, spinning fine yarnand winding bobbins. The processing method overcomes the defects of poor evenness, much filoplume, obvious defects, uneven and obviously different strength and the like so as to effectively enhance the quality of the yarns and meet the requirements of high-grade knitted fabrics.

Description

technical field

[0001] The invention relates to the textile field, in particular to a viscose fiber pretreatment and a processing method of polyester and viscose blended knitting yarn. Background technique

[0002] Polyester and viscose blended yarn not only has the advantages of good luster, high strength and wrinkle resistance of polyester fiber, but also has the advantages of good moisture absorption and ventilation, soft hand and good drapability of viscose fiber. It has become the most widely used yarn in the field of knitting products. line variety.

[0003] The knitting yarn is fed from several or dozens of ways, and each yarn is interwoven in a loop, its structure is loose, the gap between the yarns is large, the unevenness in the single yarn is easy to appear, and the unevenness between adjacent yarns will be easily seen. Affect the appearance. Therefore, knitting yarn requires uniform evenness, less detail, less belly yarn, less neps and impurities, and the twist...

Examples

Embodiment

[0046] Production of 32S65T / 35R polyester and viscose blended knitted yarn.

[0047] (1) Pretreatment of viscose fiber

[0048] Lay the unpacked viscose fiber manually, mix it with crude oil and warm water at 40°C in a ratio of 22:1 and spray it evenly on the surface of the viscose fiber in a mist form. The product of Chemical Co., Ltd.; after spraying, wrap the viscose fiber with plastic cloth and store it in the warehouse for 30 hours.

[0049] (2) Open cleaning process

[0050] The process flow is FA002 automatic cotton picker→A034 mixed opener→FA106 porcupine opener→SFA161 vibrating cotton feeder→A076E(F) single-handed roll forming machine, in which 6 roving slivers are sandwiched during roll forming.

[0051] (3) Carding process

[0052] Using FA212 carding machine, the speed ratio of cylinder to thorn bar is 2.05:1.

[0053] (4) Drawing process

[0054] Use FA317 drawing frame with 3 draw frames, and the relative humidity of the workshop is controlled at 65% to 70%. ...
