[0037] Preparation Example 1: Antimicrobial Agent Slurry A

[0038] A solution of 9.76 wt% antimicrobial agent and 2.44 wt% stearic acid in dimethylacetamide was ground in a machine (DCP-SUPERFLOW 170, Drais Mannheim, Germany) with zirconia balls (diameter: 0.5 mm) to disperse the antimicrobial agent. Microbial agent slurry. The antimicrobial agent used here is a glass metal compound containing 62.1mole% ZnO, 31.1mole% SiO 2 , 2.5mole% P 2 o 5 , 2.3mole% Al 2 o 3 and 2.0mole% Na 2 O, and have an initial mean particle diameter of 3.5 μm. Specifically, 0.1 tons of antimicrobial agent, 0.025 tons of stearic acid, and 0.9 tons of dimethylacetamide were added to the slurry preparation vessel. Thereafter, dispersion of the slurry was carried out in the grinder at 600 rpm while circulating the slurry at a rate of 24 kg / min through the pipe between the vessel and the grinder. After milling for 40 hours, the filterability test was performed by passing the dispersed slurry throu...

Abstract

Disclosed herein is a process for preparing an antimicrobial elastic fiber. The process comprises: mixing a glass compound, as an antimicrobial agent, containing ZnO, SiO2, and an alkali metal oxide, and having an average particle size of 0.1 m to 5 m, with a dispersant; sand grinding or milling the mixture; and adding the ground or milled mixture to a solution of a segmented polyurethane polymer to prepare an elastic yarn. The process can provide advantageous effects that spinnability is improved and the color of yarn remains unchanged.

Description

technical field [0001] The present invention relates to a kind of method for preparing antimicrobial elastic fiber, more particularly relate to a kind of method for preparing antimicrobial elastic fiber, this method comprises mixing glass compound and dispersant, the glass compound as antimicrobial agent contains ZnO, SiO 2 and an alkali metal oxide and have an average particle size of 0.1 μm to 5 μm, then sand or grind the mixture, and add the sanded or ground mixture to the solution of the segmented polyurethane polymer. Background technique [0002] Polyurethane elastic fiber has excellent elasticity and elastic recovery. Due to these advantages, polyurethane elastic fibers are widely used as materials for stockings, women's underwear and flexible fabrics, and their application continues to extend to aerobic fitness clothes and swimming suits. [0003] Various bacteria and molds adhere to clothes and survive on various substances secreted by the human body. Among these,...
