Problems solved by technology

When the polyester and viscose blended knitting yarn adopts the conventional spinning process, due to the uneven passage, it is easy to cause defects such as blockage, hanging, entanglement, winding, floating ends and flying flowers to attach, resulting in poor yarn quality, excessive hairiness, The problem of defects is prominent, and the difference in uneven strength is significant

Embodiment

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

[0047] (1) Viscose fiber pretreatment

[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 the form of a mist, and use Tianjian Huasenhaobo with crude oil The product of Chemical Co., Ltd.; after spraying, wrap the viscose fiber with plastic cloth, stack it, and let it stand for 30 hours.

[0049] (2) Opening and cleaning process

[0050] The process flow is FA002 automatic plucking machine → A034 mixed opener → FA106 porcupine opener → SFA161 vibrating cotton feeder → A076E(F) single hand lapping machine, in which 6 roving slivers are inserted into the lap.

[0051] (3) Carding process

[0052] Using FA212 carding machine, the speed ratio of cylinder and goad is 2.05:1.

[0053] (4) Drawing process

[0054] Use the FA317 draw frame with 3 draw frames, and the relative humi...

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 yarn and 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 field of textiles, in particular to a method for pretreatment of viscose fibers and polyester and viscose blended knitting yarns. Background technique [0002] Polyester and viscose blended yarn not only has the advantages of polyester fiber such as good luster, high strength, and anti-wrinkle, but also has the advantages of viscose fiber such as good moisture absorption and breathability, soft hand feeling, and good drape. It has become a widely used yarn in the field of knitting products. line variety. [0003] The knitting yarn is fed by several or dozens of routes, and each yarn is individually formed into a loop and interlaced with each other. The structure is loose, and the gap between the yarns is large. Affect the appearance. Therefore, the knitting yarn requires evenness, less details, less belly yarn, less neps and impurities, and the twist should be properly reduced under the premise of ensuring yarn strength. ...
