Hint: Terylene is a synthetic polyester fibre. It is produced by polymerizing ethylene glycol and terephthalic acid. It is widely used in textile industries to make hard wear clothes like sarees and dresses. It is also used to make a wider variety of clothes.
Complete answer: Terylene fibre was first discovered by two chemists Lanca and Shire in 1941. It is a synthetic polyester fibre which is made by a process of polymerizing ethylene glycol and terephthalic acid. The ethylene glycol and terephthalic acid are obtained from petroleum. It is widely used in textile industries. It is used to make hard wear clothes like sarees, dresses etc. It is used to make a large variety of clothes when it is mixed with cotton and wool. There are several properties of terylene as follows: Terylene has an elastic nature and it possesses the property of resist creasing. Hence, it requires very less ironing. It is a strong fibre. Neither bleaching nor dry cleaning agents can harm it. It is non-injured by acidic substances during the moderation process. It can wash easily and it absorbs very little water and dries very quickly. It is resistant to friction. It is very stable at high temperatures. It is insoluble in most organic solvents, and resistant to acid and alkalis. The five uses of Terylene are as follows: Terylene fibre is used as polyester tricot knit as a fashion garments fabric. It is mainly used in making plastic bottles, sheets, ropes, nets and sails. It is also used to make hard wear clothes like dresses, toestry, raincoat, fleece jackets and dress material. It is used to make nonwoven needle punched carpet which is particularly used for exhibition purposes. It is also used for the laundry usage as an automatic clothing vacuum packaging machine.
Note: Terylene fabric is characterized by its lightness and crease resistance. This fibre can be produced chemically. The major disadvantage is that it cannot be easily procurable by the yard. It is harmful for nature. It does not absorb moisturiser. It is also very costly.
