DTY Yarn: Elastic Star in the Textile Field

In the textile industry, DTY Yarn (polyester low-elastic yarn) has become an important member of chemical fiber products with its unique elasticity and wide application fields. The full name of DTY Yarn is Draw Textured Yarn, which is made of polyester chips (PET) through a series of complex process.

The production of DTY Yarn starts with polyester chips (PET), which is a fiber-forming polymer made of terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation. Polyester chips are melt-spun to obtain pre-oriented yarn (POY), which is then drawn and false-twisted to obtain DTY Yarn. In this process, POY is given a higher degree of orientation and a certain degree of elasticity, making it an ideal raw material for making DTY Yarn.

The production process of DTY Yarn has the characteristics of short process, high efficiency and good quality. The drafting process further orients the fiber molecular chain, improving the fiber's strength and elastic modulus; while the false twisting process gives the fiber curl and bulkiness, making it more suitable for subsequent textile processing and terminal applications.

DTY Yarn is known for its physical properties. It has high breaking strength and elongation at break, which means that the fiber can maintain good integrity when subjected to external forces and is not easy to break. At the same time, DTY Yarn also has good curl shrinkage and boiling water shrinkage, which enable it to better adapt to the tension changes of the loom during the weaving process and ensure the dimensional stability of the fabric. In addition, the oil content of DTY Yarn is also carefully controlled to ensure that its antistatic, smooth and other properties meet the requirements of use.

The wide application field of DTY Yarn is one of the important reasons why it is so popular. As an ideal raw material for knitting (weft knitting, warp knitting) or weaving processing, DTY Yarn is suitable for making a variety of clothing fabrics and home textiles. For example, fine-denier DTY Yarn is particularly suitable for making imitation silk fabrics, which have a soft luster and a comfortable feel; while medium-coarse-denier DTY Yarn can be used to make imitation wool fabrics, giving the fabric a crisp and warm feel. In addition, DTY Yarn is also widely used in automotive interiors, construction engineering, footwear and clothing materials, etc., meeting the diverse needs of different industries for material performance.

In recent years, with the continuous development of the global textile industry and the increasing diversification of consumer demand, the market prospects of DTY Yarn have become increasingly broad. On the one hand, with the improvement of environmental awareness, the research and development and application of environmentally friendly DTY Yarn such as recycled polyester fiber will become an important trend in the industry; on the other hand, with the advancement of science and technology and the rapid development of downstream industries, the demand for differentiated and functional DTY Yarn will continue to grow. Especially in high-end markets such as automotive interiors and home textiles, high-performance and high-value-added DTY Yarn will have greater room for development.
