The most typical representative of two-component composite elastic fiber is DuPont's early development of "T400" fiber, which has received great attention since it is available. T400 composite fiber is a new type of elastic composite fiber, which is made by PTT and PET two-component materials, not only solving the problem of traditional spandex such as not easy to dye, excessive elasticity, complicated weaving, unstable fabric size, and easy-to-aging during use. It can be directly woven on air-jet, water-jet and rapier looms, not necessary to make into covered yarn at first like spandex before it can be weaved on the machine, which improves the quality uniformity of the product.

However, due to the limitation of the supply of one of the raw materials PTT, the price of T400 and PTT/PET fiber produced by other companies later is relatively expensive, with limited market application. Many companies at home and abroad have begun to develop PDO and PTT in the early days after seeing the development potential of this fiber and the high profit of its feedstock. Domestic companies have also cooperated with universities to develop their own production technology and put into industrial production, which is also a breakthrough in the bottleneck of PTT raw materials. At the same time, in order to solve expensive price issue of the fiber, composite elastic fiber such as SSY/SPH, T800 has also been introduced to the market, and also received a good response, enjoying sharply rising demand. For example, the hottest elastic fabric in the Shengze market this year is a T800 fabric, which effectively replaces some demand of the T400 and expands the demand field for elastic fabrics.

In general, as consumers' demands for wearing comfort continues to increase, it is believed that more and more textiles will have elasticity in the future, and in addition to spandex, polyester elastic fibers may be the most cost-effective option. From the early polyester high-elastic yarn, T400 fiber, to the current SSY/SPH, T800/T8 fiber, new polyester elastic fiber is constantly accepted and popularized by the market, and the market heat even exceeds spandex. The future demand is anticipated to possess huge growing potential.
