Problems solved by technology

However, the fabrics produced by this production method in the past can only be used as fabrics for low-grade shirts.
The reason is that after the fabric is washed, the fabric will foam and wrinkle due to the difference in shrinkage between the polyester filament and cotton in the fabric, and it can never be used as a fabric for high-end shirts.

Embodiment Construction

[0017] The production method of regenerated polyester filament and cotton 55 / modal 45 siro yarn interweaving high-grade shirting fabric comprises the following steps:

[0018]

[0019] 1. Cotton 55 / Modal 45 siro-spun yarn:

[0020] According to the shrinkage changes of cotton single yarn and modal yarn after dyeing, the dimensional stability of pure cotton yarn after dyeing is relatively good, and the shrinkage rate is about 1%. Compared with viscose fiber, modal fiber has been greatly improved in strength and other aspects. However, the shrinkage of modal yarn after dyeing is close to 10% or even greater than that of viscose yarn. By analyzing the difference in shrinkage after dyeing of cotton yarn and modal yarn, the inconsistency of these two raw materials is fully utilized. The two raw materials are mixed according to different ratios, and finally it is determined that the ratio of cotton and modal is the most favorable according to the ratio of cotton 55 / modal 45, an...

Abstract

A method of producing shift fabric interwoven with recycled polyester filament yarns and modal cotton includes: firstly, siro-spinning cotton 55 / modal 45 into yarns; secondly, pretreating the recycled polyester filament yarns; thirdly, re-beaming; fourthly, drafting; fifthly, weaving; and sixthly, post-finishing and dyeing. The recycled polyester filament yarns and the cotton 55 / modal 45 siro-spun yarns are re-beamed and subjected to different pretreatment and are then interwoven into a gray fabric, the gray fabric is dyed into shell fabrics in various colors to substitute yarn dyed fabrics, and one gray fabric can be dyed into the shell fabrics in various required colors according to color change of pigments, so that production cost is reduced greatly, production period is shortened greatly, and requirements of various customers are also met. The shell fabric is interwoven with two types of raw materials, so that the problem of post-dyeing wrinkling is solved, the recycled polyester filament yarns and the cotton 55 / modal 45 siro-spun yarns are interwoven into the shell fabric which can serve as the shell fabric of high-grade shirts.

Description

technical field [0001] The invention relates to a production method of a high-grade shirt fabric, in particular to a production method of a high-grade shirt fabric interwoven with regenerated polyester filament and cotton 55 / modal 45 siro-spun yarn. Background technique [0002] Yarn-dyed shirts have always been a high-end shirt demand in our daily life. It is favored by consumers for its comfortable wearing and novel designs and colors. However, its production and processing are complicated and the production cycle is relatively long. In other words, when you need to change a color, you need to start with dyed yarn. Therefore, fabric producers consider interweaving polyester filaments and cotton yarns to weave gray fabrics, and then use the difference in color absorption of polyester filaments, polyester cationic filaments, polyester black silk and cotton to go through one-time dyeing and forming, and dye them into the desired fabric. Fabrics of various colors are used in...
