Manufacturing method of yarn with water repellency

Abstract

The invention relates to a manufacturing method of a yarn with water repellency for weaving cloth, comprising the following steps of: providing at least one yarn to be treated by using a feeding unit; then guiding the yarn to be treated by using a plurality of guiding units to make the yarn to be treated sequentially pass through one medicine tank containing water repelling agents for attaching the water repelling agents and a thermal treatment unit to allow the water repelling agents to be fixed on the yarn to be treated, forming a yarn with water repellency, and then winding the yarn with the water repellency by using a receiving unit.

Description

technical field [0001] The invention relates to a method for manufacturing yarn, in particular to a method for manufacturing water-repellent yarn for weaving cloth. Background technique [0002] Generally, fabrics with water-repellent function are usually manufactured by forming the cloth and finishing dyeing, and then processing the water-repellent agent. For example, coating, dipping, pressure-absorption, etc. can be used to attach the water-repellent agent to the cloth, and then At a heating temperature of about 170-210°C, the water-repellent agent is heat-set and fixed on the cloth. [0003] Because the cloth area is large or the thickness is thick, it is difficult for the water-repellent agent to adhere to the cloth evenly, and it is easy to produce spots of the agent, which makes the quality of the cloth surface poor. Or, the water-repellent agent has poor permeability to fibers, which will also lead to water-repellent fastness. bad. Furthermore, because the general ...

Problems solved by technology

[0003] Because the cloth area is large or the thickness is thick, it is difficult for the water-repellent agent to adhere to the cloth evenly, and it is easy to produce spots of the agent, which makes the quality of the cloth surface poor. Or, the water-repellent agent has poor permeability to fibers, which will also lead to water-repellent fastness. bad

Furthermore, because the general dyes are easy to sublimate at high temperature under the temperature environment where the water-repellent agent is heat-set, the color fastness of the cloth is poor.

And when the water repellency or dyeing fastness is poor, it is necessary to re-wash, re-dry, shape and dye, which will undoubtedly increase many unnecessary processes, resulting in waste of process time, cost and energy

[0004] As mentioned above, the current water-repellent processing process of weaving fabrics, in addition to the problems of chemical spots or poor water-repellent fastness caused by the water-repellent agent, is also caused by the heat-setting process of the water-repellent agent. The problem of poor dyeing fastness of the cloth even requires re-washing, drying, setting and dyeing, resulting in waste of process time, cost and energy, so it is really necessary to improve
