    During the war nylon replaced Asian silk in parachutes. By the 1950s man-made fibres took 20% of the fibre needs with another fibre called Acrylic. Meanwhile another fibre named polyester was invented in Britain by condensation polymerization of ethylene glycol with terephthalic acid. The best thing about polyester is its strength. The suitability of polyester over nylon helped it to occupy 54% of the textile market. So, by the 1953 the majority of man-made fibres were discovered. After that some new fibres also invented such as bullet stopping Kevler, and fire and electricity proof Nomex.…

(Signature)Project Report on Effects of Acids & Bases on the Tensile Strength of FibresObjectives"Project Report Effects of Acids & Bases on the Tensile Strength of Fibres"The aim and objective of this project is to(i) Compare the tensile strength of given samples of nylon and cotton fibres.(ii) To investigate the Effect of Acids and Alkalies on the tensile strength of these fibres.IntroductionDepending upon the sources, the various types of fibres can be classified into the following three main categories :(i) Animal fibres e.g. Wool & Silk. (ii) Vegetable Fibres e.g. Cotton & Linen. (iii) Synthetic Fibres e.g. Nylon & Polyester. Besides their chemical composition and properties, most important property of these fibres is their tensile strength. Tensile strength mean the extent to which a fibre can be stretched without breaking and it is measured in terms of minimum weight required to break the fibre. To determine the tensile strength of any fibre, it is tied to a hook at one end and weighted are slowly added to the other end until the fibre break.Since peptide bonds are more easily hydrolyzed by bases than acids therefore HYPERLINK "http://www.allprojectreports.com/PREPARE-THE-RAYON-THREADS-Chemistry-Project.htm" wool and silk are affected by basis not by acids. It is because of this reason that wool and silk threads breakup into…
