Abstract

The invention discloses a high-fill-power down preparation method. The method includes steps: washing raw down, dewatering, drying, and removing residual dust to obtain premade down; mixing humic acidand potassium hydroxide solution, heating, stirring, adding epoxidized soybean oil and graphene, oscillating, adding sweet potato protein powder, adjusting a system pH value to 8.8-9.4, adding aminopropyl-terminated polycyanopropyl methyl siloxane, continuing stirring, performing microwave treatment, distilling for water removal, and performing freeze drying to obtain a premade material; adding adetergent into the premade down, performing fine washing, rinsing with clean water, dewatering, adding the premade material and chitosan, well mixing, impregnating, filtering, washing, drying and cooling to obtain high-fill-power down. The high-fill-power down prepared according to the method is high in fill power, low in damage, great in antibacterial function and low in dust content, the antibacterial performance of the high-fill-power down does not decline after repeated washing, and original elasticity and compression performance of the down can be recovered, so that fill power of the down is guaranteed.

Description

technical field [0001] The invention relates to the technical field of down, in particular to a method for preparing down with high bulkiness. Background technique [0002] With the improvement of people's living standards, the demand for down is also increasing, and the quality requirements for down are also getting higher and higher. The fluffy problem of down is a key factor affecting the quality of down. At present, the fluffing process of down will cause great damage to the structure of down, and the dust content of down after fluffing treatment is very high, and the dust removal effect is relatively poor. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a preparation method of high-lofty down. The resulting high-lofty down has good fiber bulkiness, less damage, good antibacterial function, and low dust content. After repeated washing, The antibacterial performance is not reduced,...
