Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0029] A kind of anti-wicking polyester filament manufacture process of the present invention comprises the following steps:

[0030] 1) Take the mixture and add it to a blender, and stir for 10 to 15 minutes at a speed of 600 to 800 rpm to obtain a flame retardant and antistatic polyester mixture. The mixture includes the following components by weight: PET slices: 30~ 40 parts, nano silicon carbide: 10~15 parts, flame retardant: 1~5 parts, antistatic agent: 1~5 parts;

[0031] 2) Send the flame...

Abstract

The invention provides a production process of anti-wicking polyester filament yarns. The production process comprises the following steps that (1), a mixture is taken to be added into a stirrer and stirred at a rotating speed of 600-800 rpm for 10-15 minutes to obtain a flame-retardant and antistatic polyester mixture; (2) the flame-retardant and antistatic polyester mixture is sent into a twin-screw extruder for heating and melting, and a melt is obtained at the extrusion temperature of 280-300 DEG C; (3) the fully melted melt is introduced into a spinning box for metering and filtering, andthe spinning is conducted through a spinning assembly to form a tow; (4), the tow is formed by side blowing cooling air; (5) the tow passes through a spinning finish solution on an oil wheel; (6) stretching and heat setting are conducted through each pair of Roller rollers; (7) an anti-wicking agent is applied; and (8) the anti-wicking polyester filament yarns are obtained by directly winding thetow. The polyester filament yarns prepared by the production process has excellent mechanical properties, the flame-retardant and antistatic polyester mixture is adopted for raw materials, so that the polyester filament yarns have good flame retardant and antistatic properties, the special spinning finish is adopted, oil applying effect is good, and the antistatic ability is high.

Description

technical field [0001] The invention belongs to the technical field of preparation of polyester filaments, and in particular relates to a manufacturing process of anti-wicking polyester filaments. Background technique [0002] Polyester filament is made of polyester filament. Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation. - Polyethylene terephthalate (PET), fibers produced by spinning and post-processing. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball. [0003] Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Due to its flame retardancy, flame-retardant polyester ha...
