Introduction to Textile Laboratory
Nowadays in all countries All over the world they put committed to environmentally friendly textiles, and more and more textiles and clothing for environmental protection are appearing on the market. Through some standard tests, it has become the development direction of brands and trading companies to meet the international requirements for textiles and apparel. Textile testing Laboratory tests include composition, color fastness, strength, pH, formaldehyde, etc. According to material classification, can also be divided into fiber test, yarn test and fabric test.
Currently there are mainly 6 famous textile universities in China, viz Donghua University, Tianjin Polytechnic University, Soochow University, Jiangnan University, Zhejiang Polytechnic University and Wuhan TExtile University. These universities have their own independent textile laboratories. Donghua University Textile Test Center serves as an example to introduce relevant instruments for experimental testing.
