Abstract

The invention aims to disclose a preparation method of anion down feather material and applications thereof in home-textile products. The preparation method comprises following steps: (1) pre-treating the down feather; (2) preparing the anion down feather fibers; (3) drying. Compared to the prior art, the anion down feather material not only has the function of releasing anions, but also has the antibacterial effect, the antibacterial rates of candida sporogenes, escherichia coli and staphylococcus aureus are all over 90%, and the antibacterial effect can last for a long period. The anion down feather quilts, which are prepared from the anion down feather material, will not generate bacteria and odors during the using process, reduce the allergy phenomenon which happens when people use the down feather quilts, so that the range of users is enlarged, and the aim of the invention is achieved.

Description

Technical field [0001] The invention relates to a preparation method of down material and its application in homespun products, in particular to a preparation method of anion down material and its application in homespun products. Background technique [0002] Air is composed of countless molecules and atoms. When molecules or atoms in the air lose or gain electrons, they form charged particles called ions; those with positive charges are called positive ions, and those with negative charges are called negative ions. [0003] The significant impact of negative ions on human health, longevity and ecology has been verified by medical experts at home and abroad through clinical practice. In low-polluted places such as forests, seashores, waterfalls, and outskirts, there is a large amount of negative ion air, the concentration of which is hundreds of times that of heavily polluted cities. People here will feel the air is fresh, breathable, relaxed, happy, and refreshed. This is recuper...
