Problems solved by technology

[0003] 1. Use the melt blending spinning process to fill the heat-sensitive discoloration agent into the fiber; this method will affect the air permeability and softness of the fiber, and also increase the adjustment of the raw material mixing ratio and processing parameters during the raw material mixing and melting process difficulty;
[0004] 2. Apply the vinyl chloride polymer solution containing heat-sensitive discoloration microcapsules to the surface of the fiber, and heat-treat the solution to make the solution into a gel to obtain reversible heat-sensitive discoloration effect; in this method, there are discoloration substances after the clothes are washed many times The content is gradually reduced, making the fabric gradually lose the disadvantage of discoloration

Abstract

The invention relates to a thermosensitive color-changing spun yarn manufacturing method which comprises the following manufacturing steps: S1, mixing polyester and a corn fiber polymer, and performing melt spinning by adopting a hollow spinning nozzle to obtain hollow fibers; s2, when the hollow spinning nozzle is used for spinning, a mixture of thermosensitive reversible color-changing microcapsules and ethanol steam is sprayed to the inner walls and the outer walls of hollow fibers respectively, and hollow thermosensitive color-changing yarn is obtained after stretching and shaping; and S3, combining and winding a plurality of hollow thermosensitive color-changing yarns, rotationally winding the hollow thermosensitive color-changing yarns together through steam flow sprayed by a steam nozzle, and winding and twisting to obtain the thermosensitive color-changing spun yarns. The thermosensitive reversible color-changing microcapsules and the ethanol steam are sprayed on the surfaces of the inner wall and the outer wall of the hollow fiber, the fiber in the obtained hollow thermosensitive color-changing yarn is fully combined with the thermosensitive reversible color-changing microcapsules, the thermosensitive color-changing effect of the hollow thermosensitive color-changing yarn can be maintained, and the hollow thermosensitive color-changing yarn still keeps good heating capacity after being washed for multiple times.

Description

technical field [0001] The invention belongs to the field of heat-sensitive color-changing spinning, and in particular relates to a manufacturing method of heat-sensitive color-changing spinning. Background technique [0002] Thermosensitive reversible discoloration microcapsules are widely used in the fields of anti-counterfeiting and decoration. At the same time, the color changing performance of clothing can also be achieved by adding thermosensitive reversible discoloration microcapsules to existing clothing fabrics. Thermosensitive color-changing fibers refer to fibers whose color changes with temperature changes. There are two ways to obtain thermosensitive color-changing fibers: [0003] 1. Use the melt blending spinning process to fill the heat-sensitive discoloration agent into the fiber; this method will affect the air permeability and softness of the fiber, and also increase the adjustment of the raw material mixing ratio and processing parameters during the raw m...
