Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics such as polybutyrate.Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. The material is used extensively in clothing.

Nylon is a generic designation for a family of synthetic polymers based on aliphatic or semi-aromatic polyamides and a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations, and have found significant commercial applications in fabric and fibers, in shapes, and in films.

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. Beside the cotton, there are so many special fabrics required and needed by customer's specification prefered.

Recently most of the global brands such as Addidas, PUMA, Quick Silver and etc have been enforcing their suppliers to use the recycle fabrics in accordance with the fatalistic trend for the evironment protection. That is now becoming a firm and formal rule as time goes by. As it were Polyester & Nylon can mainly be made from Recycle resin technically as well as this technology is being developed continuously so as to make other fabrics.
