T400 elastic fiber is a modified high elastic yarn using DuPont functional materials and technology. Weaving without weaving and direct weaving has excellent elasticity and elastic recovery. The fabric is soft to the touch, UV-resistant, chlorine-resistant, high-temperature resistant, etc., with bright colors and high taking performance. It has the characteristics of good elasticity, permanentness, fatigue resistance, long time without disappearing, good stability, excellent moisture wicking function and so on.
The biggest difference between T400 and spandex covered yarn in weaving is that it exhibits elasticity after heat treatment shrinkage, uniform shrinkage, and the cloth surface will be smoother. This is in contrast to the spandex-coated yarn, which is already present due to the elasticity of the spandex-coated yarn, making it difficult to control the weaving tension, and it is not easy to ensure the quality of the cloth surface after the cloth surface is formed. In addition, the elasticity of the spandex-coated yarn itself may vary, and this control is even more difficult.
At present, T400 weaving can be used as long as the fabric needs a certain elasticity. Because of the elasticity, the wrinkle resistance is greatly improved, that is, the memory function in the traditional sense, and the comfort is improved by the existence of elasticity. This is why spandex and T400 will be a kind of bulk textile raw materials.
In addition, as long as it is anti-wrinkle, elastic, ironable, comfortable fabrics such as women's clothing, casual materials, shirt materials, etc., T400 is the best raw material.
