Abstract

The invention discloses a preparation method of a negative ion textile fabric with an air purification capability. The method includes the operation steps of (1) carrying out ball milling treatment onelbaite and chromium-magnesium tourmaline to obtain negative ion powder; (2) adding a silane coupling agent KH-570, 3-allyl-5, 5-dimethyl hydantoin and the negative ion powder into deionized water, adding an initiator and methyl methacrylate, and performing polymerization reaction to obtain modified negative ion powder; (3) adding terephthalic acid, ethylene glycol, an antioxidant, the modified negative ion powder and an acetaldehyde ammonia tripolymer into a reaction kettle, and performing condensation polymerization to obtain polyurethane slices; and (4) putting the polyurethane slices anda polylactic acid-glycolic acid copolymer into a screw extruder for spinning treatment, and weaving to obtain the negative ion textile fabric. The negative ion textile fabric with the air purificationcapacity prepared by the method is high in negative ion generation amount, excellent in moisture permeability and air permeability and excellent in wrinkle resistance.

Description

technical field [0001] The invention belongs to the technical field of textile fabric preparation, and in particular relates to a preparation method of an anion textile fabric with air purification capability. Background technique [0002] Negative ions have special health care functions for the human body. The health care functions of negative ions have been recognized by the medical community, and negative ions have been applied to various fields of human beings. [0003] (1) Purifying the environment Most of the impurities that pollute the air environment have positrons, and these positrons will neutralize the negative ions in the air, reducing the concentration of negative ions in the air, resulting in poor air quality. It can be deduced from this that when the concentration of negative ions in the air increases, it will also neutralize the tiny particles in the air, causing the particles to settle to the ground, making the air fresh and improving the air quality level [...
