  2. TYPES OF SYNTHETIC FIBRES.... A) RAYON... B)NYLON.. C)POLYESTER & ACRYLIC....

  3. RAYON • Fabric obtained from silk fiber was very costly. But its beautiful texture fascinated everybody. • Attempts were made to make silk artificially. Towards the end of the nineteenth century, scientists were successful in obtaining a fiber having properties similar to that ofsilk.

  4. Such a fiber was obtained by chemical treatment of wood pulp. This fiber was called rayon or artificial silk. • Although rayon is obtained from a natural source, wood pulp, yet it is a man-made fiber. • It is cheaper than silk and can be woven like silk fibers.

  7. Nylon is another man-made fibre. In 1931, it was made without using any natural raw material (from plant or animal). It was prepared from coal, water and air. It was the first fully synthetic fibre.

  8. Nylon fiber was strong, elastic and light. It was lustrous and easy to wash. So, it became very popular for making clothes. • We use many articles made from nylon, such as socks, ropes, tents, toothbrushes, car seat belts, sleeping bags, curtains etc. Nylon is also used for making parachutes and ropes for rock climbing . A nylon thread is actually stronger than a steel wire.

  11. POLYESTER AND ACRLIC • Polyester is another synthetic fiber. Fabric made from this fiber does not get wrinkled easily. It remains crisp and is easy to wash. So, it is quite suitable for making dress material. • You must have seen people wearing nice polyester shirts and other dresses. Terylene is a popular polyester. It can be drawn into very fine fibers that can be woven like any other yarn…

  12. We wear sweaters and use shawls or blankets in the winter. Many of these are actually not made from natural wool, though they appear to resemble wool. • These are prepared from another type of synthetic fibre called acrylic.
