Embodiment 1

[0031] A light-resistant and anti-aging high-speed rail seat cover manufacturing method (see attached figure 1 And attached figure 2 ), including the weaving step, most of the weaving step and the dyeing step in the weaving step are prior art, and will not be described in detail. The difference between this embodiment and the prior art is that the white yarn used in the weaving process has a hollow section Made of polyester fiber, hollow section polyester fiber manufacturing methods include:

[0032] S1. Mix full-dull polyester chips, UV-resistant polyester masterbatch and modified flame retardant DHQEP in a mass ratio of 1±0.05:1±0.05:7±0.3; this embodiment follows the ratio of 1:1:7 proportion to mix;

[0033] S2. The mixture is melted and extruded through a spinneret at a spinning speed of 580-620m / min, cooled and formed to obtain polyester fibers, the pre-crystallization temperature during spinning is 168-172°C, and the pre-crystallization time is 33-37min; This embodi...

Embodiment 2

[0047] This example (see attached Figure 5 ) is basically the same as that of Example 1, the difference is self-sufficiency, this embodiment adds an electrostatic adsorption block 4 on the basis of Example 1, and the electrostatic adsorption block is fixed on the modified polyester fiber with a fineness of 850D At the center position of the hollow spinneret hole, the electrostatic adsorption block runs through the spinneret, and the power supply of the electrostatic adsorption block is supplied by a wire from the input side of the spinneret. The electrostatic field of the electrostatic adsorption block can be Adjust the electrostatic field, when the melting bulge at the seal is large, start the electrostatic adsorption block to increase the inward deformation of the molten fiber filament.

Abstract

The invention relates to a method for manufacturing a light-resistant and anti-aging high-speed rail seat cover. The invention solves the problems of the prior art. The key point of the technical solution is that it includes a weaving step. Made of fiber, the hollow section polyester fiber manufacturing method includes: S1, using full-dull polyester chips, anti-ultraviolet polyester masterbatch and modified flame retardant DHQEP according to the mass ratio 1±0.05:1±0.05:7±0.3 The ratio of mixing; S2, the mixture is melted and extruded through the spinneret at a spinning speed of 580-620m / min, cooled and formed to obtain polyester fibers, the pre-crystallization temperature in spinning is 168-172°C, and the pre-crystallization time is 33-37min; S3. Prepare TiO2-SiO2 composite sol by sol-gel method, and then apply TiO2-SiO2 composite sol on the surface of polyester fiber to form a film layer.

Description

technical field [0001] The invention belongs to a manufacturing method of a seat cover, and relates to a light-resistant and anti-aging high-speed rail seat cover and a manufacturing method thereof. Background technique [0002] On September 23, 2018, as a train of MTR Dynamics departing from Hong Kong West Kowloon Station passed the Shenzhen Gaofeng Reservoir Super Bridge, the development of my country's high-speed rail technology took another big step forward. In the past ten years, China's high-speed rail has made great achievements in road network construction, technological innovation, and industrialization capabilities. By the end of 2018, China had opened and operated nearly 30,000 kilometers of high-speed railways. The high-speed rail network with "four vertical and four horizontal" as the skeleton It has basically taken shape. According to the recent annual construction plan issued by the China Railway Corporation, the mileage of newly-started railways in 2019 is ex...
