Preparation process of fluffy, warm-keeping and anti-mildew down quilt

Abstract

The invention discloses a preparation process of a fluffy, warm-keeping and anti-mildew down quilt. The preparation process has the advantages that filling down feather fibers are preprocessed to remove impurities and dust on the down feather fibers, then the down feather fibers are modified, sterilizing and antibacterial active N<+> is introduced into the down feather fibers, the pre-modified down feather fibers is mixed with metal ions, phenolic hydroxyl groups and alcoholic hydroxyl groups on the pre-modified down feather fibers can complex with Ni<2+> and Fe<3+>, and the antibacterial andanti-mildew performance of the down fibers is further increased; in addition, the warm-keeping performance of the down feather can be increased by introducing the Ni<2+> and the Fe<3+> which have goodfar infrared radiation ability into the down feather fibers, and the introduced Ni<2+> and Fe<3+> can generate a static effect to increase the fluffiness of the down feather; the preparation processis scientific and reasonable, the defect that existing down feather fibers are not resistant to mildew is improved, the down feather fibers can still have good antibacterial and anti-mildew performance after repeated washing, and the prepared down quilt is good in washability.

Description

technical field [0001] The invention belongs to the technical field of quilt processing, and in particular relates to a preparation process of a fluffy, warm, mildew-resistant down quilt. Background technique [0002] Down fiber is a natural protein fiber derived from waterfowl animals. It is similar to wool and silk in composition. It is a macromolecular structure formed by condensation of various α-amino acids. The surface of down fiber is composed of a bilayer of triphosphate The cell membrane is composed of a membrane, and the inner layer is the feather protein that makes up the down fiber. Various forms of connections are produced between the down fiber macromolecules, including salt bonds, amide bonds, disulfide bonds and hydrogen bonds. These connections make the polypeptide The chains are twisted and intertwined with each other to form a rope structure, so there are more spaces between the down fibers, so that the down fibers have a certain degree of fluffiness and c...

[0002] Down fiber is a natural protein fiber derived from waterfowl animals. It is similar to wool and silk in composition.

Various forms of connections are produced between the down fiber macromolecules, including salt bonds, amide bonds, disulfide bonds and hydrogen bonds. These connections make the polypeptide The chains are twisted and intertwined with each other to form a rope structure, so there are more spaces between the down fibers, so that the down fibers have a certain degree of fluffiness and can store still air, so the down fibers have light weight and good thermal performance, etc. Features, it is mainly used as filling material for thermal products, and down quilt is the best choice for consumers to keep warm bedding, but down fiber is a kind of natural protein polymer material, accompanied by animal fat, after processing Repeated degreasing and cleaning still cannot completely eliminate impurities and bacteria, and after a long period of use, the duvet will inevitably be stained with stains and other substances, creating favorable conditions for the growth of bacteria, resulting in mildew of the duvet, which is not suitable for continued use , even after cleaning, there is no guarantee that all molds will be killed, which is not conducive to human health
