Embodiment 1

[0030] Example 1 uses polylactic acid (PLA) as raw material, and 21SPLA yarn uses warp-knitted fabric to weave a warp-knitted base fabric. The steps are as follows:

[0031] 1. Warping: Take PLA superfine fiber with a monofilament density of 1.0dtex*38mm as raw material, spun into 21S knitting yarn to make cheese. Place the package yarn on the creel of the warping machine, and wind it into a warp beam in parallel, uniform speed and neatly under the same tension according to the number and length required by the warp knitting process.

Embodiment 2

[0056] Example 2 Using polybutylene succinate (PBS) staple fiber with a monofilament linear density of 1.2dtex*38mm as raw material, 16SPBS yarn was woven with warp knitting base fabric by warp weave, the steps are as follows:

[0057] 1. Warping: Using monofilament linear density 1.2dtex*38mm polybutylene succinate fiber staple as raw material, it is spun into knitted yarn and made into cheese. Place the package yarn on the creel of the warping machine, and wind it into a warp beam in parallel, uniform speed and neatly under the same tension according to the number and length required by the warp knitting process.

[0083] Example 3 uses polylactic acid (PLA) and polybutylene succinate (PBS) staple fibers as raw materials, and 21SPLA and PBS blended yarns are fabricated by warp knitting based on a flat weave. The steps are as follows:

[0084] 1. Warping: Polylactic acid (PLA) superfine fibers with a monofilament linear density of 0.8dtex*38mm and polybutylene succinate (PBS) staple fiber with a monofilament linear density of 1.0dtex*38mm as raw materials, blended The ratio is 50:50, and it is spun into 21S knitting yarn and made into cheese. Place the package yarn on the creel of the warping machine, and wind it into a warp beam in parallel, uniform speed and neatly under the same tension according to the number and length required by the warp knitting process.

Abstract

The invention discloses biodegradable warp knitted filter material base cloth and a preparation method thereof. The biodegradable warp knitted filter material base cloth is prepared by a warp knitting and weaving manner and through the steps that a polylactic acid (PLA) fiber and / or a poly butylene succinate (PBS) short fiber are / is taken as a raw material for spinning, and is made into a warp beam. The warp knitted filter material base cloth has excellent heat-resistant quality, is not liable to deform and can be degraded by microorganism after losing efficacy, the environment pollution is avoided, green and sustainable development conception can be met, and the reproducible cost is low.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and specifically relates to a biodegradable warp knitted filter material base cloth and a preparation method thereof. Background technique [0002] Since the reform and opening up, the national economy has grown rapidly. "Scientific and technological innovation and independent innovation" have become the mainstream of domestic industrial development. my country's manufacturing industry is gradually developing towards intensive, energy-saving, emission-reducing, and low-carbon development. While China is experiencing rapid development of the national economy, it has also brought severe environmental problems. In recent years, my country's large-scale long-term smog, air pollution, especially PM2.5 pollution has gradually entered the public eye, and all sectors of society have paid extensive attention. Atmospheric pollution not only seriously affects people's lives and human health, but also sounds an...
