3D-printing aerogel down fabric and production process thereof

Abstract

The invention discloses a 3D-printing aerogel down fabric and a production process thereof. The 3D-printing aerogel down fabric structurally comprises a bottom layer fabric, a binding layer, a wind-proof breathable layer, a columnar aerogel foaming body, an elastic down locking layer, a down layer and a surface layer fabric, wherein the columnar aerogel foaming body comprises an air bag layer, a gel body, an aerogel layer hot melt adhesive and aerogel. Compared with a traditional technology, the 3D-printing aerogel down fabric is additionally provided with the columnar aerogel foaming body, which can successfully fix the aerogel to the fabric, so that a double protection method is adopted to avoid powder dropping in the process of use. In addition, the aerogel enables the whole fabric to have good air permeability and light weight as well as efficient heat preservation effect, the inner waterproofness is realized by virtue of the water-repellent performance of the aerogel, and the comfort is ensured through the all-around elasticity.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a 3D printed airgel down fabric and a production process thereof. 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. Because it i...

Problems solved by technology

However, the biggest problem with this process is that it is very dangerous

[0006] Its 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
