Hint: The fibre also known as viscose (viscous solution of cellulose) and a regenerated cellulose fibre made from natural sources of cellulose such as wood and related agricultural products. It has the same molecular structure as cellulose.
Complete step by step answer:
Regenerated Fibres are created by dissolving cellulose areas of plant fibre in chemicals and making it into fibre again. Since it contains cellulose as cotton and hemp, it is also called Regenerated cellulose fibre.
From the above options,
Nylon-6,6 is a nylon copolymer made up of two monomers each containing six carbon atoms. Monomers are Hexamethylenediamine and Adipic Acid. So, it is not a regenerated fibre.
Terylene is an artificial textile fibre made from a polyester , used to make light and crease-resistant clothing, bed linen and sails. It is also not a regenerated fibre.
Nylon-6 is a polymer made up of only one monomer which is caprolactam. It is also called polycaprolactone and it is a semicrystalline polyamide. It is also not a regenerated fibre.
Rayon is a natural based material that is made from the cellulose obtained from wood pulp or cotton. It is also called viscous and also has the same molecular structure as cellulose. It is a regenerated cellulose fibre.
Hence, option D is correct.
Additional Information:
Rayon is a versatile fiber and is widely claimed to have the same comfort properties as natural fibers. Rayon fabrics are soft, smooth, cool, comfortable, and highly absorbent, but they do not always insulate body heat, making them ideal for use in hot and humid climates, although also making their "hand" (feel) cool and sometimes almost slimy to the touch.
Note:
Rayon is produced by dissolving cellulose followed by the conversion of this solution back to insoluble fibrous cellulose. Principally, the methods are the Cuprammonium method, Viscose method, and the Lyocell Process.
