How do you know whether a particular fibre is wool or not? Well! a question that comes to our mind every time we buy woollen products, be it online or from a store. To differentiate between wool and acrylic fibres is a little difficult because they resemble each other to a great extent.
Wool is textile fibre obtained from sheep and other animals including cashmere and mohair from goats, quivit from muskoxen, angora from rabbits and other types of wool from camelids. It mainly contains protiens together with few percent of lipids.
Acrylic is synthetic fibre made from a polymer (polyacrylonitrile) which is strong and warm and is often used for sweaters and tracksuits and as linings for boots and gloves as well as furnishing fabrics and carpets. It is manufactured as a filament , then cut into short staple lengths similar to wool hairs and spun into yarn.
To check whether a particular fibre is wool or acrylic we can follow the steps given below:
1) Carefully remove several fibres from the cloth.
2) Hold it with the help of a metal wire clip or tweezer.
3) Burn the fibres with a lighter flame or matchstick.
If the fibre is woollen then it will sizzle and curl away and give a strong odor of burning hair/ feathers, with a sharp hint of sulphur.
