Problems solved by technology

In this polyester, when the fiber is subjected to post-processing such as weight reduction or dyeing, the polyethylene glycol is dissolved due to the decomposition of the ester bond formed by polyethylene glycol and polyester, so that the fiber loses the antistatic effect

Embodiment 1

[0044] Add bishydroxyethyl terephthalate into the esterification reaction layer, keep the temperature at 250°C and the pressure at 1.2×10 5 Pa, 10 parts by weight of TPA (terephthalic acid) and 4.5 parts by weight of EG (ethylene glycol) slurry were gradually added to the esterification reaction layer within 4 hours, and then the esterification reaction was carried out for 1 hour. Finally, 12.3 parts by weight were taken from the obtained esterification reaction product and added to the polycondensation reaction layer.

[0045] Keep the esterification reaction product at 250°C under normal pressure, add a defoamer (methyl silicone oil) equivalent to 0.01% of the polyester weight and phosphoric acid equivalent to 18ppm of the polyester weight in terms of phosphorus atoms, and stir for 5 minutes Add antimony trioxide equivalent to 230ppm of polyester weight in terms of antimony atoms, cobalt acetate equivalent to 15ppm of polyester weight in terms of cobalt atoms, and titanium o...

Embodiment 2

[0047] Add the Y-10000 (structure shown in formula 4 that is equivalent to polyester weight 5wt%) in the polycondensation reaction, R 1 Be ethylene, molecular weight 10000g / mol), other are with embodiment 1.

Embodiment 3

[0049] In the polycondensation reaction, Y-4000 equivalent to 15 wt% of the polyester weight was added, and the others were the same as in Example 1.

Abstract

The invention discloses antistatic polyester, a preparation method and application of the antistatic polyester. The antistatic polyester comprises polyether with amino end groups and sulphonate. The polyether with the amino end groups overcomes the defect of easy hydrolyzation of polyether with hydroxyl end groups, so that the antistatic performance can be still maintained after the antistatic polyester is dyed or reduced. By aid of the sulphonate, the additive amount of the polyether with the amino end groups is reduced to guarantee the spinnability of the antistatic polyester. The antistatic polyester can be widely applied to fibers.

Description

technical field [0001] The invention relates to an antistatic polyester and its production method and application. Background technique [0002] The dielectric constant and electrical conductivity of conventional polymer materials are very low, and fibers made of polymer materials are prone to static electricity when rubbed, which brings difficulties to post-weaving processing and causes easy staining during the use of the fabric. Dirt, sticky dust and other problems. Therefore, it is becoming more and more important to endow these polymer materials with antistatic properties. [0003] The current methods to improve the conductivity of materials include coating antistatic agents on the surface of molded products or using antistatic agents or conductive particles that have antistatic effects during polyester synthesis or blending. However, for the former method, the antistatic agent coated on the surface will slowly fall off with the prolongation of use time, and there is n...
