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-end products in the existing flax wet spinning, which is not conducive to the diversified development of flax products, limits the promotion and application of flax products to a large extent, and restricts the flax industry. development of

Embodiment 1

[0022] Utilize the technology of the present invention, produce 50 public support pure linen yarns and 50 / 2 public support flax strands. The process is as follows: Feed flax long hemp roving (90 wt %) and water-soluble vinylon roving (10 wt %) at a certain interval (14 mm) on the wet spinning frame of long hemp after the boiling and bleaching process, to achieve two Mixing of the former, and twisting the sliver output by the front roller into a yarn, the metric twist coefficient is 0.8, spinning out a linen / vinylon blended yarn with a fineness of 45 metric counts, and then putting the blended yarn into the de-dimensional In the aqueous solution used (bath ratio 1:10), after boiling and washing for 0.5 hours, the vinylon fibers were dissolved (removed), and 50 metric pieces of pure linen yarn were obtained.

[0023] Such as figure 1 As shown, it is a schematic diagram of mixing flax roving and water-soluble vinylon roving. The mixing method of flax roving and vinylon rovi...

Embodiment 2

[0028] Utilize the technology of the present invention, produce 50 public support pure linen yarns and 50 / 2 public support flax strands. The process is as follows: the flax short linen roving 9 accounting for 70 wt% after the boiling and bleaching process is fed to the short linen wet spinning spinning frame and the water-soluble vinylon roving 10 accounting for 30 wt% is kept at a certain distance (10mm) at the same time to realize The two are mixed, and the sliver output by the front roller is twisted into yarn, the metric twist coefficient is 0.9, and the fineness is 35 metric counts of flax / vinylon blended yarn, and then the blended yarn is put into the backing machine. In the aqueous solution for maintenance (bath ratio 1:15), after 2 hours of boiling and washing, the vinylon fiber is dissolved (removed), and 50 metric pieces of pure linen yarn are obtained.

[0029] The flax / vinylon blended yarn of obtained 35 public counts is carried out reverse plying, the ratio o...

Embodiment 3

[0033] Adopt the present invention to spin the strands of the pure linen yarn of 120 public support and 120 / 2 public support. The process is as follows: in the long linen wet spinning frame, 50 wt% of the boiled and bleached flax long linen roving and 50 wt% of the vinylon roving are kept at a distance of 6mm and fed to the rear roller 6 together, drawn by the wet spinning frame, and added After the twist coefficient is 0.9, the flax / vinylon blended yarn of 60 metric counts is prepared, and then put into the aqueous solution for weaving (bath ratio 1:20), boiled for 4.5 hours, washed and dissolved After dropping the vinylon fiber therein, the pure linen high-count yarn of 120 metric counts is obtained.

[0034] The flax / vinylon blended yarn of 60 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 60 / 2 public counts can be obtained, and then the strands...

Abstract

The invention provides a method for producing linen wet spinning high count yarns and plied yarns, which is characterized by comprising the following specific steps of: after boiling linen lines or linen tow rough yarns off and bleaching, feeding the processed linen lines or linen tow rough yarns and water-soluble vinylon rough yarns on a wet spinning frame jointly for mixing to obtain blended yarns of linen / water-soluble vinylon; boiling the blended yarns in aqueous solution, and dissolving and releasing vinylon fibers to obtain pure linen high count yarns; and stranding and twisting the blended yarns reversely to form plied yarns, and releasing vinylon to obtain linen high count plied yarns or releasing the vinylon of the blended yarns, and stranding and twisting to obtain the linen high count plied yarns. In the method, the pure high count linen yarns and the plied yarns can be spun by the conventional linen fibers, so the problems that the conventional high-quality linen raw materials are deficient and the linen high count yarns are limited within the range of between 36 and 60 metrical yarn counts are solved, and the development of high count, high grade and variety diversification of linen products is realized.

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. At present, the spinning process of flax long linen wet spinning is mainly: beating into hemp (humidification and health preservation)→combing→slivering→draw...
