How does DTY Yarn affect product quality and performance?

DTY Yarn, as a type of textured yarn of polyester chemical fiber, occupies an important position in the modern textile industry. From raw material selection, production process to final product quality and performance, DTY Yarn plays a vital role.

1. Production and characteristics of DTY Yarn
DTY Yarn is made from polyester chips (PET) as raw material, spun polyester pre-oriented yarn (POY) at high speed, and then processed by drafting and false twisting. This production process gives DTY Yarn unique properties, such as short process, high efficiency, and good quality. At the same time, DTY Yarn also has good elasticity and stretchability, which make it widely used in textiles.

2. The impact of DTY Yarn on product quality
Stiff yarn problem: During the production process of DTY Yarn, if stiff yarn (segmented, continuous and unfluffy tightly twisted yarn) occurs, it will have a serious impact on product quality. After dyeing, stiff silk will be significantly darker than normal silk and appear in strips, resulting in a decrease in the appearance quality of the product. In order to reduce the impact of stiff yarn on product quality, process parameters need to be strictly controlled during the production process to ensure product quality.
Silk cake package size and molding issues: Silk cake package size and molding quality also have an important impact on product quality. Especially loose silk cakes are prone to overlapping and breakage during warping and unwinding, which affects the quality of the warp beam. Therefore, it is necessary to strictly control the package size and molding quality of the silk cake during the production process to ensure stable product quality.

3. The impact of DTY Yarn on product performance
Linear density and curl shrinkage: The linear density and curl shrinkage of DTY Yarn are important factors affecting its performance. Linear density, also called fineness, represents the thickness of the fiber. Appropriate adjustment of pre-oriented yarn (POY) fineness and elastic stretch ratio can change the linear density, thereby affecting the feel and appearance of the product. The curl shrinkage rate gives the fabric a certain elasticity. According to the elasticity requirements of the fabric, different curl shrinkage rates are required. Stretch fabrics and bandages require high curl shrinkage, while sewing threads and armband products with high gloss requirements require low curl shrinkage.
Elasticity and stretchability: DTY Yarn has good elasticity and stretchability, which makes the textiles made of it more comfortable during wearing and use. Whether it is sportswear, casual clothing or home textiles, DTY Yarn can provide excellent elasticity and stretchability to meet consumers' needs for comfort.
Wear resistance and pilling resistance: The wear resistance and pilling resistance of DTY Yarn also have an important impact on the performance of its products. During the use of textiles, wear resistance and pilling resistance are directly related to the service life and appearance quality of the product. By optimizing the production process and raw material selection, DTY Yarn can significantly improve its wear resistance and pilling resistance, thereby improving the overall performance of the product.

DTY Yarn, as a type of textured yarn of polyester chemical fiber, plays an important role in the quality and performance of products. By strictly controlling the production process and raw material selection, and optimizing product design and development, the performance and application scope of DTY Yarn can be further improved. At the same time, for consumers, understanding the characteristics and performance of DTY Yarn will help them choose textile products that are more suitable for them.
