A kind of short bast fiber spinning wet spinning blending method

Abstract

The invention provides a method for wet-spinning and blending of bast fibers, which comprises the steps of blending and humidifying the noils generated when the bast fibers are combed, combing, combing, combing, combing, roving, and boiling. Bleaching, short hemp spun yarn, drying and winding, characterized in that, after bast fibers are bleached, the resulting bast fiber rovings are mixed with rovings or filaments of other fibers on a spinning frame. The method for blended fibers does not need to be boiled and bleached together with bast fibers, which solves the defect that the performance of the blended yarn is affected by the damage to the blended fibers by the cooking and bleaching agent in the traditional wet-spinning blended spinning, and the spun blended yarn has The yarn body is smooth and clean, less hairiness, evenness, and good wear resistance. In addition, the method can give full play to the respective advantages of bast fibers and blended fibers, while the weaknesses are complemented, and the process is simple, which is beneficial to improve the quality of bast fiber blended yarns, and realize the development of bast fiber products to high count, High-end and variety development.

Description

technical field [0001] The invention relates to a short bast fiber spinning wet spinning blending method, which belongs to the technical field of textile engineering. Background technique [0002] Flax wet-spinning blended yarn is carried out on flax wet-spinning process equipment, but due to the particularity of flax spinning process and equipment, wet-spun blending of flax is difficult, and there are few studies on it. At present, a very small amount of reported flax wet-spun blending is in the form of sliver blending, that is, long or short hemp sliver is mixed with wool fiber, silk fiber, chemical fiber and other new fibers on a drawing frame or a carding machine. It is spun into mixed linen strips. Among them, the short-spinning wet spinning blending process is as follows: the nodding produced when bast fibers are combed is mixed and humidified, combed, needled, combed, needled (hemp combined), needled (hemp and hemp) Other sliver), roving, bleaching, spinning, drying...

AI Technical Summary

Problems solved by technology

[0003] However, the existing flax wet-spun blending has the following problems: in order to remove the colloid and impurities in the flax fiber and improve the splitting degree and whiteness of the flax fiber, after the roving process, the roving made by blending must be boiled and bleached, that is, blending The fiber should be scoured and bleached together with the flax fiber, and the auxiliary agents such as acid, alkali and oxidant in the scorching and bleaching reagent will damage the strength and elongation of the blended fiber, and the effect of the blended fiber cannot be fully exerted. Affect the properties of blended yarn

[0004] Due to the existence of the above problems, the existing flax wet-spinning and blending method cannot give full play to the excellent characteristics of various fibers, is not suitable for the production of high-count, high-end products, and is not conducive to the diversified development of flax product varieties, which limits to a large extent It hinders the promotion and application of flax products and restricts the development of flax industry
