Dyeing and finishing technology for PFY (polyester filament yarn) Huayao fabric

Abstract

The invention discloses a dyeing and finishing technology for PFY (polyester filament yarn) Huayao fabric. The technology comprises an open-width desizing process, a dyeing process and a setting process; a dyeing agent adopted in the dyeing process comprises a dyeing auxiliary and a dye, the dye is a disperse dye, and the dyeing process adopts a high-temperature and high-pressure overflow dyeing machine for dyeing; the initial dyeing temperature of the dyeing process is 90 DEG C, and the heat insulation time is 10 min; the formula of the dyeing auxiliary comprises components as follows: glacial acetic acid with concentration of 0.8 g/L, a superfine polyester fiber high-temperature levelling agent TF-212K with concentration of 1.2 g/L, a high-temperature levelling agent MDL01 with concentration of 0.8 g/L, peregal O with concentration of 0.2 g/L, a color-remanding agent S-8231 with concentration of 0.2 g/L and a chelating disperse agent TF-510C with concentration of 0.8 g/L. With formulation of the appropriate open-width desizing process, dyeing process and setting process, the dyeing effect of the fabric is improved, dyeing uniformity is good, so that the fabric has high color fastness, good color repeatability and good dimensional stability, touches good and meets the related wearing requirement.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing process of polyester filament Huayao fabric. Background technique [0002] As a product with a good market reputation, polyester filament Huayao fabric is composed of 100% polyester. Generally, it can be divided into three categories: weft twisted, warp twisted and warp and weft twisted. Its fineness ranges from 50D There are corresponding products to 100D. The monofilaments of pure polyester stretched yarn are straight and smooth, closely arranged with each other, and have poor bulkiness, so they can only be used for spinning fabrics, which limits their application. For this reason, a variety of modification methods are used to add new properties to expand the application range, and twisting is one of the important methods. After twisting the fiber, its yarn-forming property is greatly improved, and other characteristics o...
