3D printing, which is a technique of constructing an object by laminating pressure and thickening by using a bondable material such as powdered metal or plastic. Earlier, the printing materials were mainly hot-melt plastics and high-temperature titanium metal, which did not touch the textiles. After a long-term market inspection, Shanghai Quanxin Weaving New Materials Co., Ltd. took the lead in setting up a research and development department in 2014 to introduce 3D printing into the textile industry.
“Traditional down is not only bloated, but also has the disadvantage of being airtight. If you want to retain the breathability, the fabric will inevitably be velvet.” Quan Xin, chairman of Quanxin, introduced. In the early days of development, they also encountered similar problems. Due to the high elasticity of the fabric, the down printing process has not been fixed, and the down will be loose during the movement. There is a hair rod behind each feather, and the hair rod will be drilled in the gap during the rotation.
To this end, the R&D team mixes two trait materials and designs a layer of “spider web” that is both elastic and viscous, covering the down to solve the problem of velvet. At the same time, the fabric is 2.5 times warmer than the equivalent wool, and the static heat radiation reaches 60% of the down jacket. “3D down fabrics contain 11 layers of structure, 2 layers of down, 1 layer of windproof material, and a lot of media materials.” The surface looks like traditional fabrics, adding 3D printing to add nest structure between materials, bringing different Autumn and winter clothing wear experience.
