Acrylic Fibers

ADVANTAGES OF ACRYLIC FIBERDue to its wicking ability and other characteristics, the

fabric designers all over world are opting acrylic fabrics for manufacturing garments for all seasons.

Not only, the acrylic fabrics are high in performance but also they have a luxurious feel and they also drape very well.

They are lightweight but have more bulk. They are comfortable to wear due to high moisture

management. Dyes can be easily applied to them and they are

colorfast. They are odour and mildew resistant too. In cold weather acrylics provide excellent insulation

and warmth without any extra weight.

Disadvantages of Acrylic Fiber

Acrylic has a bad reputation amongst some crafters who knit or crochet; acrylic yarn may be perceived as "cheap" because it is typically priced lower than its natural counterparts. The fiber requires heat to "block" or set the shape of the finished garment, and it isn't as warm as alternatives like wool. Some knitters also complain that the fiber "squeaks" when knitted.

Production of Acrylic Fiber

Acrylic fibers are produced by two basic methods of spinning (extrusion), dry and wet. In the dry spinning method, material to be spun is dissolved is a solvent. After extrusion through the spinneret, the solvent is evaporated, producing continuous filaments which later may be cut into staple, if desired. In wet spinning, the spinning solution is extruded into a liquid coagulating bath to form filaments, which are drawn, dried, and processed .

Acrylic fiber is a synthetic fiber that closely resembles wool in its character. It was first developed in the mid-1940s but was not produced in large quantities. Strong and warm, acrylic fibre is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets.

USES OF ACRYLON

Characteristics of acrylic fibre

#1 Acrylic fibre has a warm and dry hand like wool. Its density is 1.17 g/cc as compared to 1.32 g/cc of wool. It is about 30% bulkier than wool. It has about 20% greater insulating power than wool.

#2. Acrylic has a moisture regain of 1.5-2% at 65% RH and 70 deg F.

#3. It has a tenacity of 5 gpd in dry state and 4-8 gpd in wet state.

#4. Breaking elongation is 15% ( both states)

#5. It has a elastic recovery of 85% after 4% extension when the load is released immediately.
