Embodiment 1

[0023] A kind of down composite thermal insulation material, its preparation method comprises the following steps:

[0024] Step S1: Soak the pinnae in the down feather in a salicylic acid solution at 60-90°C for 0.5-1h, take it out and wash it with clean water for 2-3 times, dry it at 60-80°C before use;

[0025] Step S2: In terms of mass percentage, after grinding 5-10% of the bulking agent into powder, and mixing with 5% of the fiber cotton, the bulking agent is mixed into the fiber cotton to obtain the fiber cotton mixed with the bulking agent;

[0026] Step S3: Add velvet and 5% cotton by mass to the pinnae obtained in step S1, then add the fiber cotton mixed with bulking agent obtained in step S2, and obtain the down composite thermal insulation material after mixing and processing .

[0027] It should be noted that, in terms of mass percentage, the added amount of the down is 80-85%, and the down includes 30% pinnae and 70% down; the bulking agent is a 1:1 mass ratio ...

Abstract

The invention relates to a down feather composite heat insulation material which comprises down feather and other filling materials, wherein other filling materials comprise flocculent cotton, fiber cotton and a swelling agent. The down feather composite heat insulation material is prepared from the following ingredients in percentage by mass: 80 to 85 percent of the down feature, 5 percent of theflocculent cotton, 5 percent of the fiber cotton and 5 to 10 percent of the swelling agent, wherein the swelling agent is a mixture of sodium bicarbonate powder and tartrate powder with the mass ratio of 1:1. The fiber cotton with the swelling agent is added into the down feature, when a down feature garment is cleaned in water, the swelling agent in the fiber cotton takes a reaction with the water, so that the fiber cotton forms a fluffy state in the down feather composite material; the space of the down feature material is increased; and the air ingredients in the down feature garment are more, so that the heat insulation effect of the down feature composite heat insulation material in the down feature garment is enhanced.

Description

technical field [0001] The invention belongs to the technical field of heat-retaining down materials, and in particular relates to a composite heat-retaining material of down. Background technique [0002] Down jacket (down coat) is a jacket filled with down filling, with a large and round shape. Generally, duck down accounts for more than half of the down jacket, and some fine feathers can be mixed at the same time. The duck down is cleaned, sterilized at high temperature, and then filled into the clothes to become a down jacket. Down jacket has the characteristics of light weight, soft texture and good warmth retention. A jacket made of nylon fabric and filled with down has a total weight of 500 to 1,000 grams, which is 1 / 6 to 1 / 2 of the weight of other warm clothes. Because the down is soft, it is used as clothing wadding and is comfortable to wear. Down is not prone to fiber hardening; the fabric is mostly made of high-density coated fabric, which can keep more air in...
