Problems solved by technology

If the covering layer is too tight, the air permeability of the final hollow yarn will be reduced, and if it is too loose, the hollow yarn will easily disintegrate. It takes a very rich textile technician to adjust the appropriate parameters to meet the needs of such items as towels and wristbands. The needs of different application textiles
At the same time, since the soluble core will form a cavity structure after the overall dissolution, the hollow yarn is prone to collapse after a period of use, making the hollow yarn flat and losing its elasticity

Abstract

The invention discloses a preparation method of blended hollow yarns. The preparation method comprises the following steps: (1) preprocessing water-soluble fibers; (2) preprocessing cellulosic fibers;(2) preparing a coating layer yarn for a coating layer, wherein the doping amount of the cellulosic fibers is 5%-30%; (4) preparing a soluble core body, wherein the doping amount of the cellulosic fibers is 70%-95%; and (5) packaging the soluble core body with the coating layer yarn so as to form a coating layer on the periphery of the soluble core body, and hydrolyzing an obtained yarn body to remove the cellulosic fibers after the subsequent textile step so as to obtain the blended hollow yarns. The coating layer is capable of dissolving small amount of the cellulosic fibers after being washed, so that the air permeation rate is increased; and the soluble core contains a small amount of the cellulosic fibers, after most cellulosic fibers are dissolved, the cellulosic fibers can be remained in a hollow pipe cavity formed by the coating layer so as to form small aggregates, so that a support force in a certain degree can be provided for the hollow pipe cavity, and the service life ofthe hollow yarn is prolonged.

Description

technical field [0001] The invention relates to the technical field of textile raw materials, in particular to a method for preparing a blended hollow yarn. Background technique [0002] The existing hollow yarn preparation method is as follows: water-soluble polyvinyl alcohol fibers are used to make a soluble core, and then the surface is wound with a covering layer, and finally the hollow yarn is obtained by dissolving the soluble core. However, in order to prevent the covering layer from losing support after the soluble core dissolves and spreading out when making the hollow yarn, it is necessary to wind the fabric of the covering layer more tightly. If the covering layer is too tight, the air permeability of the final hollow yarn will be reduced, and if it is too loose, the hollow yarn will easily disintegrate. It takes a very rich textile technician to adjust the appropriate parameters to meet the needs of such items as towels and wristbands. and other different applic...
