Textile and Fiber Materials

Rayon is a synthetic fibre but it uses cellulose as one of the raw materials for its formation. Polyester and acrylic are also the examples of synthetic fibres but nylon was the first one to be prepared synthetically without using any natural source as raw material. 

Rayon is prepared by treating cellulose with sodium hydroxide (NaOH) and then with carbon disulphide (CS₂). This process is called regeneration of cellulose. That is why rayon is known as regenerated fibre.

The fiber used for making cloth should have certain characteristics like it should be light in weight, should not have dull surface i.e. should be shiny / lustrous, should be strong / durable and should posses some elasticity. Tensile strength, easy moulding and being a regenerated fiber has nothing to do with making clothes.

Swim wear has nothing to do with the strength of fibre and its tensile strength. Swim wear should have easy contact with water and it should also get dried up quickly. Nylon possesses this dip and dry property and therefore, it is used to make swim wear.

The prime quality of the material used for making parachutes and ropes should be its great strength. It means that the material should not break easily. Nylon fibre is even stronger than a steel wire. Therefore, it is used for the formation of parachutes and ropes. 

Umbrella is used to protect oneself from rainwater. It means that it should soak less water and should get dried up easily. Synthetic fibres possess the characteristic property of soaking less water and getting easily dried. Therefore, they are used for making umbrellas.

 Synthetic fibers are cheap and have a long life. It means that they are durable and are easily available, which make them popular. Catching fire easily certainly won't make them popular. 

Cotton, silk and wool are natural fibres, while polyester is a synthetic fibre. Natural fibres are costlier and need more maintenance. So, one should buy polyester. 

 Nylon, Rayon, Polyester are synthetic fibers, while cotton is a natural fiber. Natural fibers always soak more water than synthetic fibers. 

 Nylon is a fully synthetic fiber while cellulose is a plant product. So, it is the cellulose, which cannot be one of the raw materials for the formation of nylon. Therefore, raw materials used for preparing nylon are coal, water and air. 

Cotton, wool and silk while natural fibers and nylon is a synthetic fiber. Natural fibers soak more water and take more time to get dried up. Synthetics fibers soak less water and get dried up quickly. So, nylon is the one which takes less time to dry up.

Polyester is a synthetic fibre which does not wrinkle easily. Teflon is a strong synthetic polymer which can be used to make non-stick cookware. Nylon is stronger than steel wire. Therefore, it is used to make parachutes. Rayon is prepared using cellulose as raw material. So, it is not a fully synthetic fibre.

Nylon is made of poly-amides. Nylon is a tough, lightweight, elastic synthetic polymer with a protein-like chemical structure, able to be produced as filaments, sheets, or molded objects.

Nylon was the first completely synthetic fiber, invented by Wallace Carothers at DuPont in 1935. Rayon is semisynthetic (made from regenerated cellulose), while Polyester and Terycott came later. Nylon's discovery marked the beginning of the synthetic fiber industry.

Rayon is known as artificial silk because it was developed as a cheaper alternative to natural silk. It has similar lustre, drape, and feel to silk but is produced from cellulose (wood pulp). Rayon is the first commercially successful semi-synthetic fibre.
