It is understood that more than 90% of China's black chemical fibers are digested in the domestic market, of which more than 60% are used in home textiles and the market associated with the home textile industry, and other application markets are mainly concentrated in industrial textiles (especially non-woven materials) and clothing. field.

In the applicability market of black chemical fiber in my country, black chemical fiber has achieved an all-round replacement for the products of the corresponding specifications of virgin PET with its high cost performance. In these market segments, the physical, chemical and mechanical properties of virgin PET fibers are the same as those of black chemical fibers, but the color of virgin fibers is better, and the products in these market segments have no special requirements for color.

Application of black chemical fiber in home textile market

Recycled PET short fibers and products are widely used as filling materials and frame materials in the bedding industry, sofas and fabric furniture, and interior decoration products.

Application of Black polyester staple fiber in the field of nonwovens

Recycled PET staple fibers are mainly used in the following non-woven fabric production processes, and their end-use markets include medical and health textiles, geotextiles and construction textiles, transportation textiles, filtration and separation textiles, safety and protection textiles and other market segments .

Production process of hot air bonded non-woven fabric (non-bonded cotton): opening → carding → laying → oven hot air reinforcement (melting low-melting fiber) → trimming + rolling → packaging;

The production process of chemically bonded non-woven fabric (sprayed cotton): opening → carding → web laying → sizing (chemical fiber adhesive) → oven hot air reinforcement (curing glue) → trimming + rolling → packaging;

The production process of needle-punched non-woven fabrics: opening → carding → laying → pre-needling → main needling (one or more needling machines) → trimming + rolling → packaging;

The production process of spunlace nonwovens: opening→carding→laying→spunlace entanglement+embossing→drying→edge trimming+rolling→packaging.

The market of black chemical fiber products for spinning purposes

Regenerated PET staple fibers for spinning (main specifications are 1.5-2D × 38-51mm) are still the varieties with the largest proportion of output, and their prices have greater advantages compared with virgin polyester, although their fabrics cannot guarantee dyeing performance , but it can still be applied to some low-end product fabrics and lining materials of mid-to-high-end products. 

In recent years, with the breakthrough of alcoholysis repolymerization technology and melt computer color matching technology, colored cotton-type recycled PET short fibers for color spinning have developed rapidly. In 2017, the output has exceeded 2.2 million tons, accounting for about 40% of cotton-type recycled PET short fibers. %. The product has various colors, bright luster, non-staining and non-fading, and the color fastness of each color is above grade 4; the product is processed by high temperature setting, and it feels soft and fine, with good elasticity and durability; the fabric has a slightly soft and elegant feeling , Good drape, with a feeling similar to silk; the fabric luster is soft and bright, and does not produce "Aurora". At present, virgin PET colored fiber products have been completely replaced in some market segments.

Application of Black polyester staple fiber in outdoor textile market

Outdoor textiles include beach mats, beach seats, travel tents, strollers and outdoor sportswear, etc. The lining and frame materials of these products are originally sponges, which cannot be compared with the anti-aging properties, flame retardancy and comfort of sponges. Compared with hard cotton (a non-woven fabric with hot air + hot calendering process), this market has now become the world of hard cotton products.
