Draw textured yarn DTY is a textured yarn type of polyester chemical fiber. It uses polyester chips (PET) as raw material and uses high-speed spinning to make polyester.
Polyester air-conditioning yarn is an elastic yarn produced using polyester filament as raw material. Because its cross section is thin and its crystallinity is low, it needs to be stretched, twisted and deformed during the production process, so that the fiber is deformed by external forces and has a special shape memory function, which can be worn in the future. During the process, there is a certain degree of stability in the overall dimensions. Polyester air-conditioned yarn has a soft feel, good fluffiness and curl. Suitable for producing sportswear, sports socks, stretch velvet fabrics, etc.
1. Differences in raw materials
There are obvious differences in raw materials between ATY yarn and DTY yarn. ATY yarn uses short fibers, usually cotton or polyester staple fibers. These short fibers need to be pre-treated during the spinning process to ensure the stability of the fibers. DTY yarn uses industrial filaments as raw materials. These industrial filaments have higher strength and elasticity, so no pre-treatment is required during the production process.
2. Different production processes
There are also differences in the production processes of ATY yarn and DTY yarn. The production process of ATY yarn mainly includes three main links: spinning, twisting and deformation. During the spinning process, short fibers need to be spun into yarn through a series of mechanical forces, and then twisted to make the yarn more elastic. Finally, the yarn is deformed to produce a special shape memory effect to achieve the desired shape. Ideal shape and performance. The production process of DTY yarn mainly includes three links: spinning, drawing and deformation. In the spinning process, industrial filaments are spun into filament bundles through melt spinning, and then the filament bundles are stretched and deformed to produce a shape memory effect, and finally crimped and finished.
3. Different appearance characteristics
The appearance characteristics of ATY yarn and DTY yarn are also different. The surface of ATY yarn is usually rough with obvious transverse stripes. This is due to the fact that the fibers of short fibers are easily entangled with each other during the spinning process. The surface of DTY yarn is relatively smooth with no obvious transverse stripes. This is because industrial filament has higher stability and less entanglement between fibers.
4. Different performance characteristics
The performance characteristics of ATY yarn and DTY yarn are also different. ATY yarn has the characteristics of good hygroscopicity, good warmth retention, strong antibacterial properties, and good antistatic properties. It is suitable for making knitted fabrics, underwear, scarves and other clothing. DTY yarn has the characteristics of good elasticity, high strength and resistance to deformation, and is suitable for the production of sportswear, sports socks, stretch velvet fabrics, etc.
5. Different prices
The prices of ATY yarn and DTY yarn are also different. The price of ATY yarn is relatively low because of its low raw material cost, relatively simple production process and high production efficiency. The price of DTY yarn is relatively high because of its high raw material cost, relatively complex production process and low production efficiency.
6. Different dyeing properties
The dyeing properties of ATY yarn and DTY yarn are also different. The dyeing performance of ATY yarn is poor because the surface area of its raw material short fiber is small, which is not conducive to the adsorption and diffusion of dye. The dyeing performance of DTY yarn is better because the surface area of its raw material industrial filament is larger, which is conducive to the adsorption and diffusion of dyes.
7. Different application fields
The application fields of ATY yarn and DTY yarn are also different. ATY yarn is suitable for making knitted fabrics, underwear, scarves and other clothing because it has good hygroscopicity, warmth retention, antibacterial properties, antistatic properties and other characteristics. DTY yarn is suitable for the production of sportswear, sports socks, stretch velvet fabrics, etc. because of its excellent elasticity, strength and stability.
To sum up, there are certain differences between ATY yarn and DTY polyester yarn in terms of raw materials, production technology, appearance characteristics, performance characteristics, price, dyeing performance and application fields. Understanding these differences can help us better select and use different types of yarn to meet different needs and requirements. At the same time, for yarn manufacturers, the production process and raw material selection can be adjusted according to market demand and customer requirements to produce yarn products that are more in line with market demand.
