Recycled Polyester staple fibre is a synthetic man made fibre made from PET/Polyester waste and post consumed PET bottles. It is used in Non-Woven carpets, wadding, filtration industries, as a polyfill for stuffing cushions, pillows, soft toys, quilts. Its also used for spinning yarns and making geotextiles. Hollow Polyester staple fiber gives good resilience properties and is used to make premium pillows, cushions and quilts. 
Recycling of PET/Polyester waste and used PET bottles is essential to maintain cleanliness of environment.
Carpet companies use recycled fibre to make polyester carpets. PET is spun into fibre filling for pillows and quilts. Fibre is also used to make clothing, jackets and even polar fleeces. PET bottles may even reappear in the form of non-woven automotive carpets.
Retailers use rPET in pillows, duvets and reusable shopping bags; automotive manufacturers use rPET in boot linings and carpets; architects and designers use rPET in the form of roof insulation; clothing designers use rPET in the manufacture of clothing – like jeans, fleece jackets, and sophisticated sportswear; engineers use rPET in industrial applications, such as strapping, geotextiles for buildings, dams, power stations and tunnels; brand owners use rPET as a blend in new bottles.
Recycled PET products are functional, cost-effective and often stylish. It seems like designers are realising the potential of how to make a business out of this sustainable material.
A more growing industrial use of recycling of PET is manufacturing Geotextiles and Geomembranes. 
some of our customers are the largest producer of RPSF, PPSF, Non woven fibre, and Geotextiles in India.
