Abstract

The invention relates to the technical field of textile processing, and particularly discloses a dyeing process of a polyester fabric. The dyeing process of the polyester fabric comprises the following steps of S1, pretreatment: carrying out pretreatment on the polyester fabric; S2, dyeing: dyeing the polyester fabric after the step S1; S3, post-treatment: carrying out post-treatment on the polyester fabric subjected to the step S2; and S4, flame-retardant after-treatment: preparing flame-retardant finishing liquid, and performing flame-retardant after-treatment on the polyester fabric treated in S3 to obtain a finished product, namely the flame-retardant polyester fabric, wherein the flame-retardant finishing liquid is prepared from the following raw materials in parts by weight of 100-150 parts of a flame retardant; 7 to 10 parts of disodium hydrogen phosphate; 60 to 100 parts of methyl etherified melamine resin; 4-5 parts of ammonium chloride; 20-24 parts of a softening agent; and 10-12 parts of a penetrant. According to the application, the polyester fabric is subjected to flame-retardant after-treatment, so that the polyester fabric has relatively high flame-retardant property and flame-retardant durability.

Description

technical field [0001] The application relates to the technical field of textile processing, more specifically, it relates to a dyeing process of polyester fabric. Background technique [0002] Polyester, also known as polyester fiber, or PET fiber for short, is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. Due to its excellent comprehensive properties, it is widely used in textiles. . [0003] Although polyester fiber has many advantages and a huge market, its LOI is only about 20%, which is a combustible fiber. In fire accidents, the fire caused by fiber textiles accounts for a large proportion. At the same time, polyester will produce molten droplets during the burning process. The molten droplets may cause the fire to spread to other places. Secondly, the molten droplets may easily cause secondary injuries such as scalds and burns. [0004] In view of the above-mentioned related technologies, ...
