Of all man made fibers, poly Ethylene Terephthalate (PET) has become the most dominant, with worldwide usage exceeding 25000 kilotons per year.
The main reason for melt spinning of synthetic fibres is to substitute or even achieve a better property than natural fibres. Price and agricultural issues of cotton fibres and on the other hand ease of production and lower finished price were caused to increase PET fibre production during past decades. In staple fibre production system, cutting length is similar to cotton or wool natural fibre. This would enable us to replace synthetic fibres with natural one.

Acrylic fibre was used for carpet production, but taking the costs and environmental harms into consideration, PET fibre could easily compete with acrylic fibres and replace it in a short period of time.
Today, you can find carpets made by 100% PET fibres or a combination of polyester-acrylic.

Recycle White 6-15 32-100 mm

In the past, Polypropylene fibre was used for moquette production, but because PP fibre has a low glass transmission temperature, it can easily be deformed by a contact with hot objects. Furthermore, polyester higher UV resistance than PP is an added reason for taking a higher share in this field of textile production.
Fill in and bedding applications such as pillows, duvet and mattress are other area of PET fibre usage.
Polyester is a prime material for nonwoven products as water tightening and sound proof insulation, road works and geo textile, agricultural, car manufacturing and filtering.
