Mention two properties and two uses each of Rayon, Nylon, Polyester, Acrylic and Spandex
Answers
Answer:
Properties of Rayon:
Rayon is very soft, cool comfortable and very good absorbent property but could not be able to protect body heat and used in humid steamy climatic conditions. Rayon fibre has the same comfort property as natural fibres. Rayon can replicate the feel and texture of silk, cotton, linen and wool.
The properties which make Polyamides suitable for plastic applications are resistance to toughness , thermal stability , good appearance , resistance to chemicals etc . The advantages of Nylon 66 are- 1. Nylon 6,6 persues excellent abrasion resistance and a high melting point
Polyester fabrics and fibers are extremely strong. Polyester is very durable: resistant to most chemicals, stretching and shrinking, wrinkle resistant, mildew and abrasion resistant. Polyester is hydrophobic in nature and quick drying. It can be used for insulation by manufacturing hollow fibers
Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics
Spandex is used in a variety of different clothing types. Since it is lightweight and does not restrict movement, it is most often used in athletic wear. This includes such garments as swimsuits, bicycle pants, and exercise wear. The form-fitting properties of spandex makes it a good for use in under-garments.

Answer:
Nyon is still used today to make parachute canopies due to its elasticity, strength, resistance to mildew, availability and price.
Rayon is used in textile industry for making textiles.Rayon is used for making tyre cords.It is also used for making carpets and surgical dressings.
Acrylic is widely used in the world today for several purposes, offering an alternative to glass due to its safe due to its safety.Spandex is a lightweight, synthetic fiber that is used to make stretchable clothing such as sportswear. It is made up of a long chain polymer called polyurethane, which is produced by reacting a polyester with a diisocyanate. The polymer is converted into a fiber using a dry spinning technique.Industrial polyester fibers, yarns and rope
s are used in car tire reinforcements, fabrics for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high-energy absorption. Polyester fiber is used as cushioning and insulating material in pillows, comforters and upholstery padding.
