Problems solved by technology

However, the biggest problem with this process is that it is very dangerous
[0006] His danger is divided into two aspects. First, during the production process, as mentioned above, airgel is very light. ash phenomenon, which means that these tiny particles are likely to pollute the environment and cause great health problems for workers
Secondly, during use, since the airgel is physically knocked into the fabric, this unstable embedded structure will cause powder drop, which will also cause certain health problems to the user

Embodiment 1

[0033] figure 1 It is a structural schematic diagram of the present invention. figure 2 It is a schematic diagram of the implementation of step 3.

[0034] Such as figure 1 and figure 2 As shown, the thermal insulation cotton containing airgel includes: bottom polyester cotton layer 100, TPU film layer 200, material layer 300 and surface layer polyester cotton layer 400, material layer 300 is wrapped in TPU film layer 200, TPU film layer 200 is set Between the bottom polyester cotton layer 100 and the surface layer polyester cotton layer 400;

[0035] Wherein, the material layer 300 includes: polyester cotton layer and 1-20% airgel, and the polyester cotton layer includes: 0-60% down, 20-99% polyester and 0-60% cupro.

[0036] The bottom polyester cotton layer 100 is made of polyester cotton, and the square gram weight range of the bottom polyester cotton layer 100 is 20 grams to 200 grams.

[0037] The surface polyester cotton layer 400 is made of polyester cotton, and...

Embodiment 2

[0057] In the present invention, the proportion of the polyester cotton layer is: 50% polyester + 48% cupro. The airgel of the material layer 300 is sprayed, and the proportion of the airgel is 2%. Down can not be added, and the present invention can still be produced. Without down, the thermal performance is reduced, but it is lighter and thinner, and at the same time, it can still heat itself through the copper ammonia wire.

Embodiment 3

[0059] In the present invention, the proportioning ratio of the polyester cotton layer is: polyester 98%. The airgel of the material layer 300 is sprayed, and the proportion of the airgel is 2%. Down and cupro can not be added, and the present invention can still be produced. Without down and cupro, the idea is the same as in Example 2. By reducing the cost, the effect of airgel can be played as much as possible, and it is also lighter and thinner.

Abstract

The invention discloses insulation cotton containing aerogel and a production process thereof. The insulation cotton comprises a bottom polyester cotton layer, a TPU film layer, a material layer and asurface polyester cotton layer, wherein the material layer is wrapped in the TPU film layer, and the TPU film layer is arranged between the bottom polyester cotton layer and the surface polyester cotton layer, wherein the material layer comprises a polyester cotton layer and 1-20% of the aerogel, and the polyester cotton layer comprises 0-60% of down feather, 20-99% of polyester and 0-60% of cuprammonium silk fibers. Compared with the traditional technology, the process successfully adds the aerogel to a fabric material safely, overcomes the problems of difficult processing, volatilization and high danger of the aerogel, and enables clothes to have good air permeability, lightness and thinness and simultaneously have high-efficiency heat preservation effect, inner layer waterproofness canbe realized due to water repellency, and simultaneously the insulation cotton has four-sided elasticity to ensure comfort.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to thermal insulation cotton containing aerogel and its production process. Background technique [0002] Airgel is a solid form of matter, the smallest solid in the world. The density is 3 kilograms per cubic meter. Because of the extremely low density, the lightest aerogel at present is only 0.16 mg per cubic centimeter, which is slightly lower than air density. Because generally more than 80% of airgel is air, it has a very good heat insulation effect, which can also be understood as it has a good heat preservation effect. [0003] To sum up, airgel is a material that is lightweight and has a strong thermal insulation effect. This means that it will be very suitable if it is applied to the field of textile fabrics. [0004] But in fact, airgel is a very difficult material to control. First of all, it is light. As its advantage, it is also the key to its difficulty in application. Becau...
