Problems solved by technology

[0002] For the dyeing and finishing of polyester yarns currently on the market, many dyeing factories are not clear about the requirement of antistatic processing. Only a few dyeing factories, although they have antistatic processing, they only simply process the surface and do not go deep into it. Improve the antistatic effect of polyester yarn, resulting in instability of polyester yarn quality

Embodiment 1

[0015] A kind of antistatic dyeing and finishing process of polyester yarn, the method comprises the steps:

[0016] Step (1) First, dye with temperature-controlled dyeing process: when dyeing polyester yarn, add leveling agent with antistatic function at the same time, then heat up to 120°C~136°C, and then keep it warm for 20~60min , and then drain at high temperature, or lower the temperature to 70°C to 90°C, and then drain;

[0017] Step (2) In the post-dyeing post-treatment process, perform reduction cleaning on polyester: after dyeing, drain the liquid. After draining, water is poured into the cylinder, and then heated to 50°C to 80°C. At the same time, add Water-saving reducing agent with antistatic function, continue to heat up to 85 ℃ ~ 95 ℃, keep warm for 5 ~ 30 minutes and then drain;

[0018] Step (3) Add softener to the cylinder body after reduction cleaning of polyester: carry out a process of water washing, enter water into the cylinder body, add softener with a...

Embodiment 2

[0020] According to the antistatic dyeing and finishing process of polyester yarn described in Example 1, the leveling agent in the step (1) is a liquid auxiliary agent with antistatic function, and the active ingredient is a nonionic polyoxyethylene ether. Organic compound, its weight portion is 40 parts.

Embodiment 3

[0022] According to the antistatic dyeing and finishing process of polyester yarn described in embodiment 1 or 2, the reduction cleaning agent in the step (2) is a liquid auxiliary agent with antistatic function, and the active ingredient is polyoxyethylene ether Nonionic organic compound, its weight portion is 35 parts.

Abstract

The invention discloses an antistatic dyeing and finishing process for a polyester yarn. The method comprises the following steps: (1) dyeing: when dyeing a polyester yarn, adding a levelling agent having an antistatic function, and heating to 120 DEG C to 136 DEG C, maintaining the temperature for 20 to 60min, then draining at high temperature, or cooling to 70 DEG C to 90 DEG C, and draining; step (2) reduction clearing: finishing the dyeing, draining, inflowing, heating to 50 DEG C to 80 DEG C, adding a water-saving reducing agent having an antistatic function, continuously heating to 85 DEG C to 95 DEG C, maintaining the temperature for 5 to 30min, and draining; step (3) addition of a softener: rinsing, inflowing, adding a softener having an antistatic function, heating to 25 DEG C to70 DEG C, maintaining the temperature for 5 to 30min, taking out the yarn, and dehydrating. During the antistatic dyeing and finishing process of the polyester yarn, the antistatic function is alwaysadded to enhance the antistatic effect of the yarn, thereby avoiding yarn breakage, yarn entanglement, yarn deformation, yarn dust collection, and weaving irregularity, and even a fire caused by static electricity.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing technology, in particular to an antistatic dyeing and finishing technology of polyester yarn. Background technique [0002] For the dyeing and finishing of polyester yarns currently on the market, many dyeing factories are not clear about the requirement of antistatic processing. Only a few dyeing factories, although they have antistatic processing, they only simply process the surface and do not go deep into it. Improve the antistatic effect of polyester yarn, resulting in instability of polyester yarn quality. Contents of the invention [0003] The object of the present invention is to provide an antistatic dyeing and finishing process for polyester yarns, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an antistatic dyeing and finishin...
