Classification and application prospects of recycled polyester staple fiber
Mar 10, 2019
With the enhancement of global environmental awareness and the popularization of the concept of sustainable development, recycled polyester staple fiber, as an environmentally friendly textile raw material, is being favored by more and more textile companies.Recycled polyester staple fiber mainly comes from the recycling and reuse of waste plastic bottles, textile scraps and other wastes. Its production process greatly reduces carbon emissions and meets the requirements of low-carbon economy. This article will introduce the main classification of recycled polyester staple fiber and its application areas.
Classification by raw material source
Recycled polyester staple fiber can be divided into two categories according to the source of raw materials: one is recycled polyester staple fiber produced from waste plastic bottles (PET bottles). This type of fiber usually has high purity and uniformity and is widely used in clothing, home textiles and other fields; the other is recycled polyester staple fiber produced from waste textiles (such as old clothes and fabric scraps). The composition of this type of fiber may be more complex, but through advanced sorting and regeneration technology, fiber products that meet textile requirements can also be produced.
Classification by fiber characteristics
According to the characteristics of the fiber, regenerated polyester staple fibers can be divided into different types such as ordinary type, high-strength type, flame-retardant type, and antibacterial type. Ordinary regenerated polyester staple fibers are suitable for general clothing and home textile products; high-strength fibers have higher strength and are suitable for industrial textiles, such as filter materials, tire cords, etc.; flame-retardant and antibacterial fibers meet the needs of specific industries by adding functional additives, such as flame-retardant fibers can be used for home decoration and automotive interiors, and antibacterial fibers are suitable for medical and sanitary products.
Application prospects
Due to its environmental protection and economy, regenerated polyester staple fibers have broad application prospects in clothing, home textiles, industrial textiles and other fields. With the advancement of technology and the improvement of the recycling system, the quality and performance of regenerated polyester staple fibers will be further improved. In the future, it is expected to replace virgin polyester in more high-end textile products and promote the green transformation of the textile industry.
Understanding the classification of regenerated polyester staple fibers will help companies choose suitable raw materials according to their own needs, thereby gaining an advantage in the fierce market competition.
