In factories, already prepared polymer chips of particular fibre are purchased and then converted into fibres. Required fields are marked *. In a tailoring shop we observe that there are many cuttings of fabrics left over after stitching. 1 (of a substance) made by chemical synthesis, especially to imitate a natural product. Unlike many other synthetic fabrics, spandex is a polyurethane, which is responsible for its peculiarly elastic qualities. These fibres can burn faster than natural fibres. Geosynthetics are synthetic products used to stabilize terrain. I don’t know if all synthetic chemicals are good, just like I don’t know if all natural chemicals are good. Nylon finds its application in seat belts of car, sleeping bags, socks, ropes, etc. Synthetic fibers are man – made from chemicals. It resists wrinkling and springs back into shape when creased. Nylon and terylene are produced through condensation polymerisation. Syntheic fibers are man-made polymers and are prepared by repeated joining of small unit known as monomer. These are also known as polymer. Byju’s is awesome. Q.2. Acrylic a synthetic fibre which is known as artificial wool. Polyester is a synthetic material, strong and easy to maintain. Spandex is used for making swimming costumes. Polyester is used in making ropes, nets, raincoats, jackets, etc. These are made by the process of polymerization. They are generally based on polymers and are stronger than natural and regenerated fibers. A synthetic fibre consists of multiple units (each of which is a chemical substance), which are joined together to form a single unit called a polymer (poly: many; mer: unit).
