because it made with plant cell and chemical. so rayon is not considered a true synthetic fiber
Rayon is not classified as a true synthetic fiber because although it is man-made, it is derived from naturally occurring cellulose. It undergoes a chemical process to transform the cellulose into fibers. This distinguishes rayon from fully synthetic fibers, which are created entirely from chemicals and petroleum-based products.
Cotton clothes do not get charged with static electricity as much as nylon clothes, as cotton is a natural fiber that does not generate static electricity as easily as synthetic fibers like nylon. Nylon fabrics tend to build up more static electricity due to their composition and structure.
Television was considered the true mass medium as it reached a large and diverse audience, shaping public opinion and influencing culture on a wide scale. It had the power to transmit information, entertainment, and advertising to millions of viewers simultaneously.
No, the concept of the universe not being real has never been considered for a Nobel Prize.
Yes, that is true - and that is commonly used in modern technology, but especially to transmit information. Note that in an optic fiber, light travelling along the fiber is simply reflected back inside, if it reaches the borders.

Rayon is usually termed a synthetic fibre despite the fact it is made from exactly the same substance (cellulose) as cotton, which is termed a natural fibre. In fact, a considerable amount of rayon is made directly from cotton by reconstituting it and drawing it into threads. Much of it is also made from the cellulose of spruce trees.
It depends on the type. Wool felt is made from sheeps wool and is a renewable resource which does not harm the sheep, the same is true for rayon blends as rayon is made from wood pulp fiber. Acrylic or crafting felt is made from plastic pellets it will degrade over time but the chemicals leech into the water cycle. Hope this helps Andie- AmericanFeltandCraft.com

true
Yes, that is true. A substance that is created through chemical synthesis rather than being naturally occurring is called synthetic.
True. Compounds and mixtures can be either synthetic or natural. Synthetic compounds are created by humans in a laboratory while natural compounds are found in nature. Similarly, mixtures can also be either synthetic or natural based on their origin.
Yes, they are true chemical elements but man made.
Whether there is a 'need' or not, synthetic fibres often possess certain qualities that natural fibres do not. There may also be economic/social reasons why synthetic fibres are produced. Nylon, for example, was invented as a substitute for silk. It is far cheaper to produce and has superior qualities such as in the manufacture of parachutes. The days of silk parachutes have long gone, sad but true. But think of all those happy silk-worms!
TRUE!
True. CFCs (chlorofluorocarbons) are synthetic chemicals that are created through industrial processes. They are commonly used as refrigerants, solvents, and propellants.
