What are the characteristics of virgin polyester staple fiber?

1. Physical properties
Good strength and toughness: The original polyester staple fiber has high tensile strength and elongation at break, which makes it not easy to break during use and can withstand certain external forces.
Uniform fineness and length: The fineness and length of the fiber are relatively uniform, which helps to improve the quality and performance stability of the product.
Good fluffiness and warmth retention: Since the fiber has a certain fluffiness, it can store a large amount of air, thus having good warmth retention performance.
Low hygroscopicity: The original polyester staple fiber has low hygroscopicity, is not easy to be affected by moisture, and can remain dry, which is very important for some application scenarios that need to be kept dry.
2. Chemical properties
Chemical corrosion resistance: It has good tolerance to chemical substances such as acids, alkalis, and organic solvents, and is not easy to be corroded.
Antioxidation: It has certain antioxidant properties, can resist oxidation to a certain extent, and prolongs its service life.
Heat resistance: It has good heat resistance within a certain temperature range and is not easy to deform or decompose.
3. Processing characteristics
Good spinnability: It is easy to carry out spinning, weaving and other processing processes, and can produce textiles of various specifications and performances.
Good dyeability: It can be dyed by a variety of dyeing methods, and the dyeing effect is good, the color is bright and firm.
Strong processability: It can be made into products of various shapes and uses through cutting, needling, hot pressing and other processing methods.
4. Environmental protection characteristics
Recyclability: The original polyester staple fiber can be recycled and reused to reduce resource waste and environmental pollution.
Poor biodegradability: Although the original polyester staple fiber itself is not easy to biodegrade, its biodegradability can be improved by adding degradable additives and other methods.
