Acrylic is the synthetic or man-made alternative to wool. It is made from the combination of coal, air, water, oil and limestone. It was first made in Germany by DuPont in 1944 and began commercial production in 1950.75% of acrylic fibres are used in apparel, 20% in home furnishing and 5% in industrial end-uses. Acrylic fibres are used in waistcoats, cardigans, jackets, socks, knee-high stockings, training and jogging suits. It is used either in pure form or blended with cotton or wool. It resembles wool in many properties such as fluffiness, warmth and softness. However, it does not absorb water. It brings the moisture to the surface of the fabric where it evaporates. It has very good shape retention, durability and quick dry qualities. It is especially suited for sportswear due to its low water absorption, quicker water transport and light and weather resistance.
