Acid Chloride Preparative Route for Nylon-6,10, which is often used in the nylon rope trick. The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.
Nylon is a fibre used to imitate silk; it is used in the production of pantyhose. Thicker nylon fibres are used in rope and outdoor clothing. Spandex (trade name Lycra) is a polyurethane product that can be made tight-fitting without impeding movement. It is used to make activewear, bras, and swimsuits.
Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate.

Most textile arts begin with twisting or spinning and plying fibers to make yarn (called thread when it is very fine and rope when it is very heavy). The yarn is then knotted, looped, braided, or woven to make flexible fabric or cloth, and cloth can be used to make clothing and soft furnishings.
Close-up photograph of the knitted nylon fabric used in stockings Nylon fibers visualized using scanning electron microscopy. While nylon was marketed as the durable and indestructible material of the people, it was sold at about one-and-a-half times the price of silk stockings ($4.27 per pound of nylon versus $2.79 per pound of silk).
1590 – First reference to Cambric fabric. [11] 1840 – Barathea developed as a cloth for mourning clothes. [12] 1892 – Cross, Bevan & Beadle invent Viscose. 1938 – First commercial nylon fiber production by DuPont. Nylon is the first synthetic non-cellulosic fiber on the market. 1938 – First commercial PTFE fiber production by DuPont.
The count often is 148 by 160 and the fabric is finished at 100 cm (40 in) wide with a length-to-mass ratio of about 13.10 m/kg (6 1 ⁄ 2 yd/lb). [2] The quality and weight of the weave can be more critical than the choice of fibers, since a poor weave can lead to high stretch and poor sail form.
