Problems solved by technology

[0002] The quilt is a tool to reduce the heat loss of the human body while sleeping. It is mostly filled with cotton fiber, silk and down. Among them, down is comprehensive because of its lower cost than silk, warmth, breathability, sweat absorption and effective service life. Performance is a commonly used quilt filling at present, but down is natural animal down, and its component is protein, so it is easy to cause damage to the duvet when cleaning it, and it cannot be exposed to the sun after cleaning. After long-term use, it is prone to moisture, bacterial growth, etc., which not only affects the quality of the duvet, but also adversely affects the health of the person who uses the duvet.

Embodiment 1

[0046] An antibacterial and moisture-proof duvet, comprising a down filler and a quilt cover, the quilt surface is divided into several diamond-shaped or rectangular areas, and the down filler fills each area with down to form an antibacterial and moisture-proof duvet;

[0047] The down filling is uniformly mixed with the following raw materials in mass percentage:

[0048] 70% modified down, 18% bamboo fiber and 12% chitin fiber, wherein the fiber length of bamboo fiber and chitin fiber does not exceed 5mm;

[0049] The method of uniformly mixing each raw material through a homogenizing tooling is as follows:

[0050] Open the vortex forming tuyere 4;

[0051] Treat the down to make the down negatively charged;

[0052] After the bamboo fiber raw material and chitin fiber are mixed and loosened, the first feeding pipe 2 is blown into the homogenizing box 1, and at the same time, the modified down is blown into the homogenizing box 1 through the second feeding pipe 3, and th...

[0074] An antibacterial and moisture-proof duvet, comprising a down filler and a quilt cover, the quilt surface is divided into several diamond-shaped or rectangular areas, and the down filler fills each area with down to form an antibacterial and moisture-proof duvet;

[0075] The down filling is uniformly mixed with the following raw materials in mass percentage:

[0076] 67% of modified down, 20% of bamboo fiber and 13% of chitin fiber, wherein the fiber length of bamboo fiber and chitin fiber is not more than 5mm;

[0077] The method of uniformly mixing each raw material through a homogenizing tooling is as follows:

[0078] Open the vortex forming tuyere 4;

[0079] Treat the down to make the down negatively charged;

[0080] After the bamboo fiber raw material and the chitin fiber are mixed and loosened, the first feeding pipe 2 is blown into the homogenizing box 1, and at the same time, the modified down is blown into the homogenizing box 1 through the second feeding ...

Abstract

The invention discloses an antibacterial and dampproof duvet and a preparation process thereof. The duvet comprises down feather filler and a quilt cover. The quilt cover is divided into a plurality of areas, and all the areas are filled with the down feather filer to form the antibacterial and dampproof duvet. The down feather filler is formed by evenly mixing, by mass, 65% to 70% of modified down feather, 17% to 20% of bamboo fibers and 11% to 17% of chitosan fibers. According to the antibacterial and dampproof duvet and the preparation process thereof, the down feather is degreased, a densealcohol and ester mixture molecular layer on the surface of the down feather is removed, the surface of the down feather can fully react to form the down feather with bacterium resisting and inhibiting capacity, the durability of the bacterium resisting and inhibiting effect is improved, then the down feather is subjected to surface modification, surface hydrophobic treatment is carried out on the down feather under the condition of not influencing the moisture absorption performance, and the modified down feather has a good antibacterial and waterproof effect. The modified down feather and mixed fibers are mixed, and the structure of the modified down feather cannot be damaged in the mixing process.

Description

technical field [0001] The invention belongs to the technical field of down product processing, and in particular relates to an antibacterial and moisture-proof down quilt and a preparation process thereof. Background technique [0002] The quilt is a tool to reduce the heat loss of the human body while sleeping. It is mostly filled with cotton fiber, silk and down. Among them, down is comprehensive because of its lower cost than silk, warmth, breathability, sweat absorption and effective service life. Performance is a commonly used quilt filling at present, but down is natural animal down, and its component is protein, so it is easy to cause damage to the duvet when cleaning it, and it cannot be exposed to the sun after cleaning. Situations such as moisture and bacterial growth are prone to occur after long-term use, which not only affects the quality of duvets, but also adversely affects the health of people who use duvets. [0003] When down is used as a filler for down ...
