Olefin Fibre name comes from the Latin word (oleum); it is the fastest growing fibre in the world.
Olefin fibre is a manufactured fibre in which the fibre-forming substance is any long-chain synthetic polymer composed of at least 85% by weight of ethylene, propylene, or other olefin units.
Olefin fibre is a generic description that covers thermoplastic fibres derived from olefins, predominately aliphatic hydrocarbons.
Olefins are products of the polymerization of propylene and ethylene gases. Polypropylene (PP) and polyethylene (PE) are the two most common members of the family
Polypropylene is extremely versatile as a fibre-forming material whereas polyethylene is not as good a fibre-forming high polymer material.
Since its introduction into the textile industry in the 1950s, the list of successful products and markets for polypropylene fibre has increased exponentially.
Manufacturing of Olefin fibres
Olefin fibres are products of the polymerization of propylene and ethylene gases. For the products to be of use as fibres polymerization must be carried out under controlled conditions with special catalysts that give chains with few branches.
Olefin fbers are characterized by their resistance to moisture and chemicals. Of the two, polypropylene is the more favored for general textile applications because of its higher melting point and the use of polypropylene has progressed rapidly since its introduction.
The fibres resist dyeing, so colored olefin fibres are produced by adding dye directly to the polymer prior to or during melt spinning. A range of characteristics can be imparted to olefin fibres with additives, variations in the polymer, and by use of different process conditions.
Properties of Olefin Fibres
- Olefin Fibres gives good bulk and cover.
- Has excellent abrasion resistance.
- Olefin Fibres Quick dries.
- Olefin Fibres has Low static electricity.
- Resistant to deterioration from chemicals, mildew, perspiration, rot, and weather.
- Olefin Fibres are thermally bondable.
- Olefin Fibres are Stain and soil resistant.
- Olefin Fibres has good Sunlight resistant.
- Olefin Fibres Dry hand; wicks body moisture from the skin.
- Very comfortable.
- Very lightweight (olefin fibres have the lowest specific gravity of all fibres).
Applications of Olefin Fibre
Active-wear and sportswear; socks; thermal underwear, lining fabrics.
Interior fabrics used in or on kick panel, package shelf, seat construction, truck liners, load decks, etc.
- Home Furnishings
Indoor and outdoor, carpets, carpet backing; upholstery and wall coverings; furniture and bedding construction fabrics.
Carpets; disposable, durable non- woven fabrics; ropes; filter fabrics; bagging, geotextiles
The Uniqueness of Olefin Fibre
- Olefin fibres are comparatively Inexpensive.
- It is very difficult to dye Olefin fibre.
- Lightest of all textile fibres (will float on water).
- Extremely heat sensitive.
- Excellent wicking abilities (wicks moisture away from the skin, so is useful for diaper lining).
- Does not absorb water (olefin fibres are hydrophobic in nature).
- Difficult to dye (can be solution dyed).
- Inert to chemicals.
- Very heat-sensitive.
General Olefin fibre Care Tips
- Most stains on fabric can be readily removed by spotting with lukewarm water and detergent.
- Bleaches can be used if needed.
- If a fabric is laundered, it should be line dried or tumble dried with gentle heat or no heat.
- Olefin dries very rapidly.
- Do not iron.
Micro-fibers are Man-made fibers which are available in acrylic, nylon, polyester, and rayon.
DuPont introduced the first microfiber in 1989, it was a polyester microfiber. However, today in addition to polyester microfibers there are also nylon microfibers that have become important in the pantyhose market, rayon microfibers, and acrylic microfibers.
One of the important characteristics of microfiber fabrics is that they can be woven so tightly that the fabric can’t be penetrated by wind, rain, or cold.
For this reason, raincoat manufacturers have become big users of polyester microfibers. Microfibers also have a wicking ability, which allows perspiration to pass through. So they’re comfortable to wear.
- Ultra-fine (less than 1.0 denier), finer than the most delicate silk.
- Extremely drapeable.
- Very soft, the luxurious hand with a silken or suede touch.
- Washable, dry cleanable.
- High strength (except Rayon).
- Excellent pleat retention.
- Insulates well against wind, rain, and cold.
Major End Uses
Hosiery, blouses, dresses, separates, sportswear, ties, scarves, menswear, intimate apparel, activewear, swimwear, outerwear, rainwear
- Home Fashion
Curtains, draperies, upholstery, sheets, towels, blankets
Care of Fabrics made of Micro-fibers
- Acrylic, nylon, and polyester micro-fibers are machine washable, machine dryable or dry-cleanable.
- Follow the instructions for washing fabrics consisting of these individual fibers.
