Problems solved by technology

Therefore, water-soluble vinylon cannot be mixed with flax fiber before the spinning process, which greatly limits the feasibility of blending or accompanying spinning of flax and water-soluble vinylon
[0005] Due to the existence of the above problems, it is difficult to produce high-count and high-grade products in the existing wet spinning of flax long and short flax, which is not conducive to the diversified development of flax products, and limits the promotion and production of flax products to a large extent. application, restricting the development of flax industry

Embodiment 1

[0023] Utilize the technology of the present invention, produce 50 public support pure flax short linen yarns and 50 / 2 public support flax strands. Such as figure 1 As shown, it is a schematic diagram of Sirofil spinning of flax roving and water-soluble vinylon yarn or filament. After the flax short roving 11 (67wt%) is boiled and bleached, it is fed through the water tank 7 (with guide roller 8) The short hemp wet-spun spinning frame enters the drafting zone, and passes through the drafting of the rear roller 6, the rear top roller 5, the light roller 4, the lower apron 3, the front top roller 2 and the front roller 1. Water-soluble vinylon yarn 12 (10tex, 33wt%) is fed at an interval of 14mm between the front roller 1 and the drafted flax sliver, mixed with the flax and then output through the front roller 1, and then added with a twist coefficient of 0.8, A linen / vinylon-sirofill blended yarn is formed. Then put the blended yarn into the aqueous solution for fiber re...

Embodiment 2

[0028] Adopt the present invention to spin the strands of pure flax long hemp yarn and 56 / 2 public support of spinning 56 common. The process is as follows: feed the boiled and bleached flax roving 11 (90wt%) to the rear roller 6 on the long hemp wet spinning frame, and through the drafting of the wet spinning frame, the front roller 1 and the 20D (2.2 tex, 10wt%) vinylon filament 12 is mixed and added after twist coefficient is the twist of 0.9, the blended yarn of flax / vinylon of 50 public support is obtained, then it is put into the aqueous solution that returns maintenance (bath ratio 1 : 20), boiled for 0.5 hours and washed to dissolve the vinylon fiber, and obtain 56 metric pieces of pure linen yarn.

[0029] The flax / vinylon blended yarn of 50 public counts obtained is reversely plyed, the ratio of the twist coefficient of the strands to the twist coefficient of the single yarn is 1.1, and a double-strand yarn of 50 / 2 public counts can be obtained, and then the str...

Embodiment 3

[0033] Adopt the present invention to spin the pure linen yarn of 150 public support and the linen strand of 150 / 2 public support. Feed the long hemp roving 11 (60wt%) of flax into the long hemp wet-spinning frame, and after drafting, merge with vinylon filaments 12 of 40D (4.4tex, 40wt%) with a distance of 4mm at the front roller 1, After twisting, a 90-count flax / vinylon blended yarn with a twist coefficient of 1.2 was obtained. Then put it into the aqueous solution for fiber removal (bath ratio 1:25), boil and wash for 6 hours, dissolve the vinylon fiber in it, and get 150 metric counts of pure linen yarn.

[0034] The blended yarn produced by the above method is reversely plied and twisted, the ratio of the twist coefficient of the strand to the twist coefficient of the single yarn is 1.3, and the blended strand of flax / vinylon of 90 / 2 public support is obtained, and then put into In the aqueous solution for fiber removal (bath ratio 1:25), after 6 hours of boiling a...

Abstract

The invention provides a method for producing flax wet-spun high count yarns and strands by Sirofil, which comprises the following steps of: scouring and bleaching long or short flax thick yarns, then feeding the thick yarns and yarns or filaments of water-soluble vinylon into a spinning frame together to realize mixing, and twisting the mixture to form flax / vinylon blended yarns; and removing the vinylon from the blended yarns to form the high count yarns and the strands, wherein the mixing method for the long or short flax thick yarns and the yarns or the filaments of the water-soluble vinylon in the spinning frame comprises the following steps of: feeding the long or short flax thick yarns after passing through a trough into the wet spinning frame from a rear roller, feeding the yarns or the filaments of the water-soluble vinylon from a front roller of the wet spinning frame, and mixing the yarns or the filaments and the drafted flax strands at the front roller. The method avoids poor fiber control during drafting the flax and the vinylon; the spun flax / water-soluble vinylon blended yarns have better quality and lower thickness; and after the vinylon is dissolved, the high count vinylon yarns or strands can be obtained.

Description

technical field [0001] The invention relates to a method for producing flax wet-spun high-count yarn and strands, belonging to the technical field of textile engineering. Background technique [0002] Linen is a natural fiber with excellent properties, known as the queen of fibers. Flax fiber absorbs moisture quickly and releases moisture quickly, and has good air permeability, making it an ideal fabric for summer wear. At present, flax spinning mainly adopts the form of wet spinning, because the single fiber length of flax is relatively short, therefore, it can only be spun with thicker technical fibers (ie fiber bundles) after semi-degumming. Coupled with the particularity of the wet spinning process and equipment, it is difficult to spin thinner yarns in the wet spinning of flax, and only thick fabrics can be made. Flax spinning is divided into long spinning and short spinning. At present, the spinning process of flax long linen wet spinning is mainly: beating into hemp...
