Problems solved by technology

However, because of its high rigidity, stiffness, and insufficient flexibility, the yarn count is low and the hairiness is high, and the spinnable count is low (36-48 public counts), and the woven fabric has a strong itching feeling, which limits the application of ramie products.
For a long time, people have been committed to the research of high branching of ramie, but the progress is limited. The existing method of spinning high-count yarn of ramie usually adopts blending of ramie and water-soluble vinylon to make blended yarn, and after weaving into fabric, it is processed in the finishing process. Dissolving vinylon, the maximum count of ramie yarn in the cloth can reach 300
[0003] But there is following problem in existing method: although the count of ramie yarn is very high in the woven fabric, can't make independent high-count ramie yarn, and after water-soluble vinylon recedes, the density and strength of ramie fabric are very low, Can only be used to make scarves, etc., not fabrics for clothing, etc.
The quality and the variety of the product produced by the method of existing ramie spinning high-count yarn are limited, which limits the promotion and application of ramie products to a large extent, and restricts the development of ramie industry

Embodiment 1

[0021] Adopt the present invention to spin the ramie strand of 100 common branch / 2, main technical process is: the twist coefficient that ramie fiber 30wt% and 30 ℃ water-soluble vinylon fiber 70wt% adopts conventional method to be spun into 13.33tex is 80 The blended single yarn, wherein the mixing method is to mix the ramie roving and the water-soluble vinylon filament on the spinning frame (during the mixing process on the spinning frame, the distance between the ramie roving and the water-soluble vinylon filament before mixing is 8mm, and the mixing method is the same as that in the patent 200810204366.5), and then remove the vinylon in water at 30°C for 4 hours after the single yarn, wash it with water after completely removing the vinylon, and then dry it at 50°C for 6 hours to obtain ramie single yarn with a fineness of 100 metric counts, and then remove the single yarn Carry out plying, obtain the strand that fineness is 100 common branch / 2, because this strand is used ...

Embodiment 2

[0024] Adopt the present invention to spin 150 / 2 common ramie strands, its technological process is: adopt conventional method to spin ramie fiber 90wt% and water-soluble vinylon fiber 10wt% into the blended single yarn that the twist coefficient of 11.1tex is 120, Wherein the mixing method is to realize the mixing of ramie roving and water-soluble vinylon filament on the spinning frame (in the mixing process on the spinning frame, the distance between the ramie roving and the water-soluble vinylon filament before mixing is 0mm, and the mixing method is the same as the patent 200810204366.5), and then Put the yarn in water at 100°C to remove vinylon for 2 hours. After the vinylon is completely removed, wash it with water and dry it at 100°C for 1 hour to obtain ramie single yarn with a fineness of 150 mm. In this example, the strands are used as It is used for knitting or weft yarn, so the twist coefficient 120 is the same as that of the single yarn, and the ramie strands with ...

Embodiment 3

[0028] Using the present invention to spin ramie strands with 300 public counts / 2 public counts, the technological process is as follows: 60 wt% of ramie fibers and 40 wt% of water-soluble vinylon fibers are spun into 5.56tex blended single yarns with a twist coefficient of 140 by conventional methods , wherein the mixing method is loose fiber mixing, and then the vinylon is removed at 100°C for 0.5 hours. After the vinylon is completely removed, it is washed with water and dried at 120°C for 0.5 hours to obtain a ramie single yarn with a fineness of 300 public counts. The single yarn can be plyed to obtain ramie strands with a fineness of 150 metric and a twist coefficient of 170.

[0029] In this embodiment, the vinylon that is soluble in water at 95°C is selected, so sodium hydroxide (2.2 g per 5 L of water) and JFC (2.2 g per 5 L of water) are added during the vinylon removal process to speed up the removal of vinylon. The ramie strand quality that present embodiment makes...

Abstract

The invention provides a production method of ramie spinning high grade plied yarn, which is characterized by comprising the steps: union yarn is manufactured by cospinning ramie and water-soluble vinylon, is boiled by water for vinylon dissolution, and then is rinsed and dried, so that ramie single yarn with the fineness of 100-300Nm; then, the plied single yarn is made into ramie pliedyarn having the fineness of 100 / 2-300 / 2Nm. The production method has the advantages that as the water-soluble vinylon is introduced, the spinnability of the ramie is improved, and the spinnable fineness of the ramie yarn and thread is greatly reduced; furthermore, the single twist multiplier can be properly reduced, and the coefficient of twist of the plied yarn can be selected reasonably according to the twisting theory, so that the resultant yarn structure of the plied yarn is more compact, the yarn body is brighter and cleaner, less filoplume is available, and the uniformity of yarn levelness is better, thus ensuring the whole quality of the plied yarn to be excellent. Therefore, the excellent properties of the ramie are fully exerted, the application scope of the ramie products is enlarged, and the method is suitable for producing the thin ramie products with high quality.

Description

technical field [0001] The invention relates to a production method of ramie spinning high-count strands, which belongs to the technical field of textile engineering. Background technique [0002] Ramie fiber has high strength, fast moisture absorption and moisture dissipation, good air permeability, antibacterial, and excellent wearability. It is a widely favored green textile raw material. However, because of its high rigidity, stiffness, and insufficient flexibility, the yarn count is low and the hairiness is high, and the spinnable count is low (36-48 public counts), and the woven fabric has a strong itching feeling, which limits the application of ramie products. . For a long time, people have been committed to the research of high-branching of ramie, but the progress is limited. The existing method of spinning high-count yarn of ramie usually adopts blending of ramie and water-soluble vinylon to make a blended yarn, and after weaving into a fabric, it is processed in ...
