By the end of 2017, China's production capacity of recycled PET fiber has exceeded 10 million t / a, ranking first in the world. It is understood that more than 90% of China's recycled PET fibers are digested in the domestic market, of which more than 60% are used in home textiles and in the market associated with the home textile industry, while other application markets are mainly concentrated in industrial textiles (especially non-woven materials). Clothing field.

In the marketability of recycled PET fiber in China, recycled PET fiber has achieved a comprehensive replacement for the original PET corresponding specifications with its high cost performance. In these market segments, the physical, chemical, and mechanical properties of native PET fibers are the same as for recycled PET fibers, except that the native fibers have better color, and the products padding fabric  in these market segments have no special requirements for color.

Application of recycled PET fiber in the home textile market

Recycled PET staple fibers and articles are used extensively in the bedding industry, sofa and fabric furniture, and upholstery as filler materials and framework materials.

Such as pillow core filling materials - simple open three-dimensional crimped hollow fiber, open loose + friction treated pearl cotton, open pine + carded doll cotton and non-cotton;

Core filled materials - sprayed cotton, non-cotton, hot air / spray compound cotton and doll cotton;

Matrix material and cushioning material inside the mattress and Simmons - no rubber, hot cotton and hard cotton;

As well as needle-punched nonwoven fabrics, carpet woven fabrics for carpet base fabrics, sofa and fabric pillow filling materials, fabric sofa cushions and armrests.

Application of recycled PET fiber in the field of nonwovens

Recycled PET staple fiber is mainly used in the following non-woven fabric production processes, and its end products application market covers medical and sanitary textiles, geotextiles and construction textiles, vehicle textiles, textiles for filtration and separation, and textiles for safety and protection. .

Hot air bonded non-woven fabric (no rubberized cotton) production process: opening → carding → laying net → oven hot air reinforcement (melting low melting point fiber) → trimming + winding → packaging;

Chemical bonding non-woven fabric (spray cotton) production process: opening → combing → laying net → sizing (chemical fiber adhesive) → oven hot air reinforcement (curing glue) → trimming + winding → packaging;

Production process of needle-punched nonwoven fabric: opening loosening → combing → laying net → pre-acupuncture → main acupuncture (one or more needle punching machines) → trimming + winding → packaging;

Spunlaced non-woven fabric production process: opening → carding → laying net → hydroentanglement + embossing → drying → trimming + winding → packaging.

Spinning Recycled PET Fiber Products Market

Recycled PET staple fiber for spinning (mainly 1.5 to 2D × 38 to 51 mm) is still the largest proportion of production, and its price is superior to that of native polyester, although its fabric can not guarantee dyeing performance. However, it can still be applied to some low-end product fabrics and lining materials for medium and high-end products.

In recent years, with the breakthrough of alcoholysis repolymerization technology and melt computer color matching technology, the use of colored cotton-type recycled PET staple fiber for color spinning has developed rapidly. The output in 2017 has exceeded 2.2 million tons, accounting for about 40% of cotton-type recycled PET staple fiber. %. The products are diversified in color, bright in gloss, non-staining, and non-fading. The color fastness is up to grade 4 or higher. The product is processed by high-temperature shaping, soft and fine to the touch, durable and durable; the fabric has a soft and soft feeling. It has a good drape and a silk-like feel; the fabric is soft and bright, and does not produce 'Aurora'. At present, it has completely replaced the original PET colored fiber products in some market segments.
