What Are The Properties Of Polyester Fibre

Here I have given physical and chemical properties of polyester fiber which is important to know.

What are the properties of polyester fibre. The majority of todays polyester fibers are composed of terephthalic acid and ethylene glycol PET. Ie because a typical fiber is long and narrow it. And have high abrasion and wrinkle resistance.

Polyester is a one type of polymers which has the ester functional group in their main chain. Sportswear brands in particular have a soft spot for this fabric due to its suitability for making athletics wear. High strength high modulus low shrinkage heat set stability light fastness and chemical resistance account for the great versatility of PET.

Both polyesters can be easily molded or thermoformed and have many attractive properties like high strength and toughness good abrasion and heat resistance low creep at elevated temperatures good chemical resistance and excellent dimensional stability particularly when glass-fiber reinforced. Physical Properties of Polyester. The various properties are- 1.

The moisture regain of polyester is 02 to 08 and specific gravity is 138 or 122 depending on the type of polyester fibres is moderate. However polyester fibers are not as strong as nylon fibers. High fiber length to width ratio.

Although it might be assumed that the fiber is weak in compression it is actually only the long aspect ratio of the fiber which makes it seem so. Since both replaced natural fibres as more sustainable alternatives with unique characteristics it may be tough to decide which one is better - nylon or polyester. Definition Fiber properties are essential thing to know for various end uses and the products made from it qualify on the basis of certain parameters.

Like cotton or other fiber polyester fiber consists of some important physical properties. The melting point of polyester is 250-300C. Properties of Polyester 1 They are stronger than nylon fibres.
