Problems solved by technology

[0003] Hydrogen peroxide is commonly used as a reagent to improve the bulkiness of down, but down fibers are very sensitive to oxidants, and the fluffy effect is limited and may even cause damage to down fibers
Aldehyde cross-linking agents are also widely used in the treatment of feather bulkiness, but aldehyde cross-linking agents are more irritating and may cause harm to operators. In addition, down treated with aldehyde cross-linking agents Yellowing will occur, resulting in quality problems

Abstract

The invention belongs to the technical field of down processing and discloses a high-fluffiness down preparation method. The method includes steps: subjecting a down sample to degreasing treatment with a degreasing agent, cleaning and draining; subjecting the degreased down sample to softening treatment with papain, cleaning and draining; subjecting the softened down sample to cross-linking treatment with glutamine transaminase, cleaning, and drying to obtain a high-fluffiness down sample. By synergistic effects between papain and glutamine transaminase, catalysis of down fiber intermolecularor intramolecular crosslinking is realized, down fiber molecular binding force is increased, and accordingly fluffiness is improved; in addition, papain and glutamine transaminase are clean and nontoxic, have no influences on the environment and accord with the sustainable development direction of the down industry; due to high efficiency of enzymes, low-fluffiness down can be treated to obtain high-end down products, and a practical significance to increase of economic benefits of enterprises is achieved.

Description

technical field [0001] The invention belongs to the technical field of down processing, and in particular relates to a method for preparing down with high bulkiness. Background technique [0002] Down fibers have natural properties such as lightness, thinness, and softness. Down products have been widely used in daily life, such as down jackets and duvets. Because the bulkiness and the like do not meet the relevant standards, it cannot be widely used. Therefore, it is extremely important to find an efficient and clean material and process. [0003] The commonly used agent for improving the bulkiness of down has hydrogen peroxide, but down fibers are very sensitive to oxidants, and the fluffy effect is limited and even damages the down fibers. Aldehyde cross-linking agents are also widely used in the treatment of feather bulkiness, but aldehyde cross-linking agents are more irritating and may cause harm to operators. In addition, down treated with aldehyde cross-linking age...
