Olefin fiber | characteristics, advantages, disadvantages

Olefin fiber

Olefin fiber is a synthetic fiber made from polyolefin. These are the products of the polymerization of propylene and ethylene gas. In order to use the products like fibers, the polymerization must be carried out in a controlled manner with the help of special catalysts which give a chain with a few branches. These fibers are characterized by their resistance to moisture and chemicals. Of the two, polypropylene is preferred for general textile applications because of its higher melting point; And the use of polypropylene has progressed rapidly since its introduction. The fibers prevent dyeing, so colored olefin fibers are produced by adding dyes directly to the polymer before or during melting. A range of properties can be provided in olefin fibers through the use of additives, polymer variations, and different process conditions.

Olefin fabric refers to synthetic fibers formed by linear macromolecules polymerized by olefin. It is a man-made fiber whose fiber structure is a long-chain synthetic polymer. This polymer is made up of at least 85% by weight of ethylene, propylene, or other olefin monomers, but without the polyolefins of rubber fiber, it has a rod-like structure with a smooth surface of a formless.

Olefin fiber characteristics

i. Olefin fibers have great bulk and cover properties when there is a less specific gravity

ii. It has low moisture absorption, but it can wick moisture and dry quickly.

iii. It is abrasion, stain, sunlight, fire, and chemical resistant

iv. It does not dye well but has the advantage of being colorfast

v. It has a low melting point, textiles can be thermally bonded

vi. These fibers have the lowest static of all manufactured fibers and a medium luster

vii. It retains its strength in wet or dry conditions and is very resilient

viii. These fibers are resistant to deterioration from chemicals, mildew, perspiration, rot, and weather

ix. These fibers are very lightweight and comfortable.

x. These are highly stain resistant.

xi. It can be multi- or monofilament and staple, tow, or film yarns

xii. Its physical characteristics are a waxy feel and colorless.

Olefin fiber advantages

i. Olefin fiber wicks moisture and dries quickly

ii. It resists fading, mildew, chemicals, and insects

iii. It is highly stain resistant

iv. It is colorfast

v. It has good abrasion resistance property

vi. It is strong

vii. It is lightweight

viii. It is easy to clean

Olefin fiber disadvantages

i. Olefin fiber has almost completely hydrophobic properties,

ii. It is not conducive to making most clothes.

iii. It sometimes generates static electricity and pilling.

iv. It is a very heat-sensitive fiber

v. It can be damaged by Friction

vi. It is very difficult to dye due to its low absorbency rate.
