Synthetic fibres are not obtained from natural resource but it is manufactured in a laboratory using petrochemicals. Synthetic fabrics aretextilesmade from man-made rather than natural fibres. Examples of synthetic fabrics include polyester, acrylic, nylon, rayon, acetate, spandex, latex, Orlon and kevlar. Synthetic (chemically produced) fabrics are made by joining monomers into polymers, through a process called polymerisation.

Chemicals used to make synthetic fabric include sodium hydroxide and carbon disulfide, which are derived from coal, oil, or natural gas (petrochemicals). Pressure forces the liquid chemicals through tiny holes called spinnerets. As the liquid comes out of the spinnerets and into the air, it cools and forms tiny threads. Manufacturers add artificial dyes to these threads before weaving them into a fabric.

Hence, the correct option is $D$
