How is the soft feel and good gloss of ECDP texture DTY yarn achieved through the production process?

The soft feel and good gloss of ECDP texture DTY yarn are achieved through a series of fine production processes, which mainly include raw material selection, spinning process, post-processing and special processing technology. Selecting high-quality ECDP polyester raw materials is the basis for producing soft and glossy DTY yarn. ECDP polyester raw materials add trimonomers and tetramonomers in the polyester production process, achieving the purpose of normal pressure easy dyeing modification, thereby solving the problem that ordinary polyester fibers require high temperature and high pressure dyeing. This raw material itself has good softness and spinnability, providing a good foundation for subsequent spinning and post-processing processes. During the spinning process, an appropriate amount of lubricants, softeners and other additives can also be added, which can further improve the softness and gloss of the fiber.
The product adopts advanced spinning technologies such as compact spinning and siro spinning, which can optimize the structure of the fiber, make the fiber more uniform and delicate, and thus improve the softness and gloss of the fiber. During the spinning process, the working parameters of the spinning equipment, such as temperature, pressure, speed, etc., need to be precisely controlled to ensure the uniformity and stability of the fiber. Precise control of these parameters is essential for improving the softness and gloss of the fiber.
The softness and gloss of the fiber can be further improved through heat treatment. Heat treatment can make the molecular chain of the fiber more stretched, thereby improving the softness of the fiber. At the same time, heat treatment can also make the fiber surface smoother and improve the gloss. In the post-treatment process, softeners can also be used to soften the fiber. Softeners can penetrate into the fiber and interact with the fiber molecules, thereby reducing the rigidity and hardness of the fiber and improving the softness.
In the production process of ECDP textured DTY yarn, eco-friendly technologies can also be used, such as using environmentally friendly dyes and auxiliaries, optimizing wastewater treatment processes, etc. These technologies can not only reduce pollution to the environment, but also improve the environmental performance and quality of the fiber.
In order to improve the electrostatic properties of the fiber, ECDP textured DTY yarn can also be treated with antistatic treatment. Antistatic treatment can reduce the accumulation of charge on the fiber surface, thereby reducing the generation of static electricity and the adsorption of dust, making the fiber softer and more glossy.
