Question

Which fiber is cellulose derivative:
A. Nylon
B. Rayon
C. Polyester
D. Wool

Answer 1

Hint:Cellulose is a molecule made up of hundreds, if not thousands, of carbon, hydrogen, and oxygen atoms. Cellulose is the major component of plant cell walls, which helps plants stay rigid and erect. Although humans are unable to digest cellulose, it is an essential source of fibre in the diet.

Complete step-by-step solution:
Rayon is a synthetic fabric created from regenerated cellulose found in natural sources such as wood and agricultural goods. Its molecular structure is identical to that of cellulose. Viscose can refer to a viscous cellulose solution. The word viscose rayon refers to rayon manufactured by the viscose method. Rayon is created from cellulose derived from wood pulp (typically from pine, spruce, or hemlock trees) and cotton linters, which are leftover fibres from the ginning process that adhere to cotton seed. The most popular and flexible rayon is viscose rayon. It may be used with synthetic or natural fibres to create textiles of various weights and textures. It's also a soft, absorbent, and cost-effective cloth to wear.
Other approaches to rayon need lignin-free cellulose as a starting material, but the viscose technique may use wood as a source of cellulose. Because woody cellulose sources are less expensive, viscose has historically been employed on a bigger scale than the other approaches. The original viscose method, on the other hand, produces a lot of polluted effluent. Newer methods consume less water and increase the wastewater's quality. Until the 1930s, when methods for using "broken waste rayon" as a staple fibre were invented, rayon was only available as a filament fabric.
Hence option B is correct.

Note:High-wet-modulus rayon is a more durable material than standard rayon, and it performs more like cotton than standard rayon. It has a greater elastic recovery than conventional rayon, and clothes made with it are easier to care for since they can be machine washed, whereas textiles made with ordinary rayon must be dry cleaned.
