Polyester yarn can be divided into spun polyester yarn and filament polyester yarn according to different production processes and applications. These two types have their own characteristics in performance, use and production methods, and are important materials for the textile industry to meet diverse needs.
Differences in production processes
Spun polyester yarn is made by twisting short fibers, and its production process is similar to the spinning process of natural fibers. This type of yarn is characterized by shorter fibers, but after twist treatment, the yarn surface shows a certain hairiness, which has a look and feel close to cotton yarn.
In contrast, filament polyester yarn is made of continuous long fibers, and the yarn surface is smooth and uniform. The production of this yarn does not require twist treatment, so it is more suitable for applications that require high strength and smooth appearance.
Differences in performance and use
The hairiness of spun polyester yarn gives it excellent moisture absorption and breathability, making it more suitable for clothing worn next to the body, such as T-shirts, underwear and home textiles. This yarn can also be blended with other natural fibers to further enhance the softness and comfort of the fabric.
Filament-type Polyester Yarn is widely used in functional clothing and industrial textiles due to its high strength and smooth surface. Its tensile strength and abrasion resistance make it an ideal material for outdoor clothing, tents, and travel bags. In addition, this yarn performs well in making high-gloss fabrics and is the main choice for products that require a gorgeous appearance, such as dresses and curtains.
Cost and processability considerations
The production process of spinning-type Polyester Yarn is relatively complex and the cost is slightly higher than that of filament-type yarn, but its soft touch and natural appearance can better meet the needs of specific markets. Filament-type Polyester Yarn has higher production efficiency, so the price is usually more competitive and suitable for large-scale applications.
Response to environmental protection needs
In terms of environmental protection, both types of Polyester Yarn can be produced through recycling and reuse processes, but the continuity and single structure of filament-type yarn make it more efficient in the recycling process. If companies are concerned about environmental attributes, they can give priority to using recycled polyester yarn to meet market trends.
