Problems solved by technology

However, the chemical composition of down is a kind of protein, accompanied by animal fat. After repeated degreasing and cleaning in the process of processing, impurities and bacteria cannot be completely eliminated.
[0003] In recent years, researches on antibacterial and deodorizing down materials are also increasing. For example, the invention patent of CN1327079C discloses a processing method of down and down with antibacterial, antiviral, mildew-proof, deodorizing and health-care functions, using chitin solvent dipping or spraying down fiber, but this method has poor combination fastness between chitin and down fiber, and the antibacterial and deodorizing effect is not obvious; in addition, there is also a method of using organic antibacterial agent for antibacterial treatment, but this method has poor safety performance and unsatisfactory efficacy persistence
[0004] The chemical composition of down is a kind of protein, accompanied by animal fat. During the treatment process, after repeated degreasing and cleaning, impurities and bacteria cannot be completely eliminated. To solve the problem of bacteria breeding during its use, a high-efficiency long-lasting antimicrobial finish

Abstract

The invention aims to disclose a manufacturing method of an antibacterial and deodorant duvet. The manufacturing method comprises the following steps: (1) pretreating down; (2) manufacturing antibacterial and deodorant down fiber; (3) drying and sterilizing by ultraviolet; and (4) manufacturing the antibacterial and deodorant duvet. Compared with the prior art, by compounding a silver-based inorganic antibacterial agent RHA-T1 of NAFUR and a chitin antibacterial finishing agent SA-50DS of Japanese TK, the down fiber has a lasting antibacterial and deodorant function under the condition that a bonding agent is not added; and by a method of filling antibacterial fiber and the antibacterial and deodorant down fiber in a mixed way, the duvet has a more lasting antibacterial and deodorant effect, therefore, the aim of the invention is achieved.

Description

technical field [0001] The invention relates to a preparation method of a down quilt, in particular to a preparation method of an antibacterial and deodorant down quilt. Background technique [0002] Down is a good natural thermal insulation material, which has the advantages of light weight, softness, and good thermal insulation. Down quilts are also the best choice for consumers to keep warm bedding. However, the chemical composition of down is a kind of protein, accompanied by animal fat. During the treatment process, after repeated degreasing and cleaning, impurities and bacteria cannot be completely eliminated. [0003] In recent years, researches on antibacterial and deodorizing down materials are also increasing. For example, the invention patent of CN1327079C discloses a processing method of down and down with antibacterial, antiviral, mildew-proof, deodorizing and health-care functions, using chitin solvent dipping or spraying down fiber, but this method has poor c...
