Embodiment 1

[0018] A highly air-permeable synthetic fiber composition comprising the following components in parts by weight:

[0019] 100 parts of polyimide fiber, 20 parts of high alumina bauxite clinker, 5 parts of calcium aluminate cement, 2 parts of polyvinyl acetate emulsion, 6 parts of cresyl diphenyl phosphate, 1 part of stearic acid, polyethylene 2 parts, 2 parts of polybutylene terephthalate.

[0020] The preparation method of the above-mentioned highly air-permeable synthetic fiber composition, its preparation steps are:

[0021] 1), take the corresponding raw material components by weight, mix and stir to form a slurry, so that the slurry is fluid;

[0022] 2) Pour the slurry into the ring mould, use the vibrating table to vibrate or hold the stirring rod to pound the slurry in the mold, so that the air bubbles in the slurry are fully removed, the slurry is dense, and then statically solidified;

[0023] 3), solidified and released from the mold, dried at room temperature fo...

Abstract

The invention discloses a high-breathable synthetic fiber composition including, by weight, 100 parts of polyimide fibers, 15-20 parts of a high alumina bauxite clinker, 5-8 parts of calcium aluminate cement, 2-5 parts of a polyvinyl acetate emulsion, 6-10 parts of tolyldiphenyl phosphate, 1-3 parts of stearic acid, 2-4 parts of polyethylene, and 2-7 parts of polybutylene terephthalate. The heat-insulation material is significantly improved in heat insulation and has excellent breathability.

Description

technical field [0001] The invention belongs to the field of fire-resistant and heat-insulating materials, and in particular relates to a synthetic fiber with high air permeability and a preparation method thereof. Background technique [0002] Polyimide fiber has good spinnability and can be made into various textiles for special occasions. Due to its high and low temperature resistance, flame retardancy, non-melting, self-extinguishing when away from fire and excellent temperature insulation, polyimide fiber thermal insulation protective clothing is comfortable to wear, good skin adaptability, permanent flame retardancy, and the size It is stable, safe, and has a long service life. Compared with other fibers, due to the low thermal conductivity of the material itself, it is also an excellent thermal insulation material. But its polyimide fiber has poor air permeability. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of t...
