Prospect Analysis Of Functional Fabric Coating Technology

　　 Protective performance does not prevent wearing comfort.

Witkey company launched a new silicone coating in June this year. Silicone coating can produce water repellent effect. Spin Products will not absorb too much moisture, and can prevent the wetting effect and weight increase.

Because of the coating agent Textile A continuous layer of film is formed on the surface, so the softness and breathability of the fabric are greatly reduced. Although it can resist rainwater and cold winds and protect the body, the coating can not effectively dissipate the heat and moisture from the human body and make people feel sick.

In order to change this shortcoming, a technology of space phase change thermostat has been developed by technicians in the US. This material is a high-tech space phase change temperature regulating fiber developed by the US space agency and used in space suit. It is coated with a layer of microencapsulated coating with phase change material on the surface of the fiber by means of high technology. Under normal body temperature, the material coexists with the solid state. Made of space temperature adjustable yarn. clothing When the human body enters a relatively high temperature environment from normal temperature, the phase change material changes from solid state to liquid state and absorbs heat. When the human body enters a relatively low temperature environment from normal temperature, the phase change material changes from liquid to solid state and releases heat, thereby slowing down the surface temperature of the human body and keeping the comfort feeling.

The latest Solgel technology developed by Nanyang Technology University Singapore Research Institute can also be used. clothing Coating treatment. The technology can produce transparent coating effect containing metal oxide or silicon oxide thin film, which can provide an alternative method for deposition of gas-phase metal oxide layer. In Solgel technology, nano sol of silicon oxide or other metal oxides is prepared by the acid or alkaline of alkoxides. The nano sol produced generally contains metal oxide 3%~20%, and the diameter of nanoparticles is less than 10 nm.

Witkey company launched a new silicone coating in June this year. Silicone coating can produce water repellent effect, so that the fabric will not absorb too much moisture, it can prevent the wetting effect and weight increase. The silicone can filter out most of the harmful ultraviolet rays in the sunlight, and the handle is soft, and can be used in high-performance sports leisure fabrics, such as making coloured directional luminescent coating fabrics. It is a novel functional coating fabric with strong "striking effect". It is mainly used for life safety protection clothing products such as lifesaving, transportation department, municipal construction, mining operation, sanitation, fire protection, etc. at night or in dark places. It can also be used for national costume, shoes Cap, packaging rain gear and so on.

　 Magical effects of different material stacking

The American conductive composites company has developed a nickel chemical vapor deposition (CVD) coated nonwovens. The development technology enables composites and polymer systems to have electrical and electromagnetic shielding (EMI) solutions.

Although the fabric and fabric lamination has developed many varieties, it still can not meet the current needs, so the laminated fabric and metal and film are also developing rapidly. Industrial coated textiles have accounted for a large part of the market for industrial textiles, involving transportation, agriculture, construction, aerospace and other industrial sectors.

Dongli, Japan, has developed a new type of protective material, which is made of laminated metal, resin layer and fiber cloth. Ito, head of the Dongli company, said that the metal in the protective material can be gold, silver, copper or aluminum, and the resin layer can be made up of coloured or colourless coating agents of poly, poly, polyphenylene, and the bottom can be Natural fiber Woven or nonwoven fabrics of synthetic fibres. Coating agent on one side or two sides of the fabric, one side of the coating agent contains carbon black conductive resin, can form conductive resin layer, so that the composite laminated fabric has different energy reflection on both sides, so that it has good protection and camouflage effect on near infrared, far infrared, electromagnetic wave and radar, especially suitable for military equipment.

The American conductive composites company has also developed a nickel chemical vapor deposition (CVD) coated nonwovens. The development technology enables composites and polymer systems to have electrical and electromagnetic shielding (EMI) solutions. Using nickel chemical vapor deposition (CVD) technology, the coating can be used on any substrate, including nonwovens and bonded nonwovens made from carbon fiber, aramid, glass fiber and carbon nanomaterials. CVD coated nonwovens are lighter, thinner and better conductive than those produced by conductive fibers. Using chemical vapor deposition, the coated sheet has very low resistivity, and the price is more competitive. It can be used for fire hose, soft roof waterproof material, wire and cable, composite cement bag and so on.

"CVD coating nonwovens With obvious performance advantages, it can save a lot of cost for our customers. Our demand in existing and developing markets is increasing. Our investment in capacity expansion and commercialization can enhance our ability to provide competitive materials to the market and become a bright spot for the company's recent development. Hansen, President of the American conductive composites company.
