Kiudpolüesterkiude

Kiudpolüesterkiude, often referred to as polyester staple fiber (PSF) in English, are short lengths of polyester yarn. They are produced by cutting continuous polyester filaments into specific lengths, typically ranging from a few millimeters to several centimeters. The raw material used is polyethylene terephthalate (PET), the same polymer used for making plastic bottles and films. The production process involves melt spinning polyester polymer, drawing it into filaments, and then cutting these filaments into staple fibers.

These fibers possess a range of desirable properties that make them widely used in various industries. They exhibit high tensile strength, good abrasion resistance, and excellent resilience, meaning they can recover their shape after being stretched or compressed. Polyester staple fibers are also resistant to stretching and shrinking, are quick-drying, and are not easily damaged by most chemicals or mildew. Their low moisture absorbency contributes to their quick-drying nature and resistance to biological degradation.

The applications of kiudpolüesterkiude are extensive. They are a staple in the textile industry, commonly blended with natural fibers like cotton to improve the durability, wrinkle resistance, and color retention of fabrics. These blends are used in clothing, home furnishings such as upholstery and curtains, and bedding. Beyond textiles, PSF is utilized as a filling material for pillows, duvets, and stuffed toys due to its loft and hypoallergenic properties. It also finds use in industrial applications like geotextiles for soil stabilization, filtration media, and reinforcing materials. The versatility and cost-effectiveness of polyester staple fiber have solidified its importance in manufacturing.
