Preparation process of a fluffy, warm, mildew-resistant down quilt

Abstract

The invention discloses a preparation process of a fluffy, warm, mildew-proof down quilt. The filled down fibers are first pretreated to remove impurities and dust on the down, and then the down fibers are modified to introduce bactericidal and antibacterial active N+ into the down quilt. In the down fiber, the pre-modified down fiber is mixed with metal ions, and the phenolic and alcoholic hydroxyl groups on the pre-modified down fiber can be combined with Ni 2+ and Fe 3+ Complexation further improves the antibacterial and antifungal performance of down fiber. In addition, Ni 2+ and Fe 3+ It has better far-infrared radiation ability, and it is introduced into the down fiber, thereby improving the warmth retention of down, Ni 2+ and Fe 3+ Introduced into the down fiber to generate electrostatic effect, which can improve the bulkiness of down; this process is scientific and reasonable, and improves the defect that the existing down fiber is not mildew-proof, and after repeated washing, it still has good anti-bacteria and anti-mold properties. The prepared duvet has good 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. It is a macromolecular structure formed by condensation of various α-amino acids.

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
