by Acrylic fibers are one of the most popular types of synthetic fibers used in clothing and other textiles. First developed in the 1940s to 1950s as an alternative to wool, acrylic fibers offer many benefits like softness, stretch, warmth, easy washability and affordability. Today acrylic fibers make up a significant portion of the fibers used globally in textiles and continue to grow in popularity.
Production and Composition
The PAN polymer is dissolved and forced through fine spinnerets to form fibers which are then treated to stabilize the structure. This converts the PAN into a durable polyacrylonitrile fiber. The final composition contains over 85% acrylonitrile monomer units.
Properties and Benefits
Some key properties and benefits of acrylic fibers include:
Softness – Acrylic fibers have a soft, wool-like texture and feel against the skin due to small microscopic scales on the fiber surface. This softness makes garments made from acrylic fibers very comfortable to wear.
Warmth – While lighter weight than wool, acrylic fibers have good thermal insulation properties and can keep the body warm. The hollow structure of the fiber traps body heat to retain warmth.
Stretch – Most acrylic fibers have some degree of stretch or elasticity built into the molecular structure. This makes fabrics made from acrylic fibers stretchy and comfortable.
Easy care – Acrylic fabrics are very durable and easy to wash without shrinking or fading. They can be machine washed and dried on regular cycles without special treatment needed.
Affordability – Acrylic fibers are relatively inexpensive to produce compared to natural fibers like wool. This lower production cost makes acrylic fiber garments and textiles more affordable for consumers.
Applications and Usage
Given their many benefits, Acrylic Fibers today find wide applications in apparel, home furnishing and industrial textiles. Some key uses include:
Apparel – Sweaters, socks, hats, scarves, gloves – acrylic fibers are very commonly used in cold weather apparel due to their warmth, softness and washability. Blends with cotton and other fibers are also widely used.
Home furnishing – Blankets, upholstery, curtains – the durable and washable nature of acrylic fibers makes them well suited for home textiles that see a lot of wear and cleaning cycles.
Industrial uses – Carpet fibers, filtration, insulation – Acrylic fibers excellent performance and bulk properties lend them to uses such as industrial carpet fibers, filtration media and insulation applications.
Blend fibers – Acrylic is often blended with natural and other synthetic fibers to optimize properties. Common blends include acrylic wool, acrylic cotton and acrylic modal for garment and home textiles applications.
Growing and Developing Applications
As acrylic fiber technology advances, new applications and improved acrylic fiber variants continue to be developed:
Microfibers – ultra-fine acrylic fibers, often under 1 denier, that are incorporated into fleeces, filters and other nonwoven media.
Flame retardant fibers – Acrylic fibers treated with chemicals or reinforced with materials to increase flame resistance for safety critical uses.
Stretch fibers – Acrylics with up to 300% stretch ability for activewear, hosiery and industrial uses requiring high stretch.
Anti-microbial fibers – Acrylics treated with silver or other agents inhibit microbial growth for medical/hygienic uses.
Sustainable acrylics – Researchers working on bio-based and recycled feedstocks for more environmentally friendly acrylic production methods.
The Future of Acrylic Fibers
Acrylic fibers have established themselves as one of the most widely used synthetic fibers globally. Their properties and versatility have helped them displace natural fibers in many applications. Going forward:
– Increased blending of acrylics with natural and other synthetic fibers to optimize properties for new end uses.
– Development of high performance acrylic variants like microfibers and technical fabrics for advanced applications.
– Continued market growth in developing countries as living standards rise and demand for affordable textiles grows.
– Ongoing research into lowering acrylic production costs and developing more sustainable manufacturing technologies.
In summary, through ongoing innovation acrylic fibers are poised to remain an important part of the global textiles industry for decades to come due to their performance, affordability and versatility compared to other fibers. Developments in new acrylic variants will also unlock future applications and expansion opportunities.
