Stretch staple fiber: new discovery of biomaterials

Recently, authoritative activities in the textile industry have brought together Shanghai. First of all, the “Shi Feng Shang Hai Lai Shi” lions feature was released at the Xijiao Hotel in Shanghai. As the first fashion protagonist of this release, Shu Shi-silk is undoubtedly a model for science and technology to help fashion; followed by the world’s largest fabric exhibition. ——intertextile fabrics exhibition also opened in Shanghai, Shu elastic yarn has won numerous eyeballs with clear advantages. As a high-tech and differentiated fiber jointly developed by Fujian Shishi Haixing Material Science and Technology Co., Ltd. and DuPont, USA, Shulan Silk is the only type of bio-elastic short fiber that reaches the industrialized production level in the world and deserves to be a low-carbon fiber. The best interpretation of environmental protection, comfort, flexibility and natural fashion.

Shu Liansheng - Zhang Lianjing, the general manager of Haixing Material Science and Technology Co., Ltd., who strictly followed Guan Shusheng's R&D process, was the first to explain the significance of the name “Shuzhengsi” to reporters. The biggest difference from the previous stretch products is that the comfortable bullets are between high elasticity and low elasticity. The elastic elastic fabrics not only retain the comfort of the elastic fabric, but also have a proper body bone, moderate elasticity, The excellent feel and good stretch resilience give the fabric its unique advantages. He said that this is because the elastic yarn is like a spring. Compared with the traditional spandex elastic fabric, it can not only give the fabric enough elasticity to satisfy the comfortable wearing experience of the wearer, but also prevent the fabric from bulging. , Relaxation, whether it is multiple stretching, sun exposure, or harsh washing and fabric post-processing, the unique molecular structure and physical form of Shusheng elastic can ensure the lasting and stable elasticity of the fabric.

"It is something like MSG that won't grab the limelight, but rather expresses the original advantages of the material. The advantage of cotton is more prominent and the characteristics of silk are more obvious." Zhang Lianjing mentioned another major feature of Shusheng. , It can be blended with cotton, wool, silk, hemp, viscose, tencel, terylene, etc. It can adapt to various spinning and printing and dyeing conditions to produce products of any specifications, and at the same time, it can maintain its original characteristics. On the basis of making the fabric more flexible and comfortable, it can not only provide natural handfeel and drape that other chemical fiber raw materials can not match, but also overcomes the poor elastic recovery of traditional spandex fabrics, intolerance to sunlight and sunlight, and elastic relaxation after multiple wears. Other disadvantages provide more possibilities for fabric development later.

Shu Sheng elastic not only has superior comfort, but also can be a representative of green raw materials. First, the raw materials are made of plant-based fibers. At the same time, the energy consumption of the production process is low, and the remaining materials can be recycled. After the treatment, the raw materials can be recycled. “The short stretch of bio-elastic fibers derived from DuPont.” This is Zhang Lianjing's most accurate positioning of Shusheng Silk. “37% of Shuan’s raw materials use non-oil renewable biomass resources, reducing the need for petroleum and petrochemical products. Dependent on the development and production of clean and environmentally-friendly production processes, it is the only type of industrial-strength, bio-elastic, short-staple fiber currently available from DuPont, which is environmentally friendly and sustainable, compared to nylon 6 produced by the petrochemical process. Fiber, producing the same amount of Shusheng Silk can reduce energy consumption by 30% and CO2 emissions by 63%, and is a green fiber that can be recycled and recycled."

Currently, Haixing Material Science and Technology Co., Ltd. and DuPont have signed an agreement to become DupontTM Sorona Short Fiber, the only licensed producer of Shusheng Silk in China.
