(b) cotton 5. . Plural of this. It has excellent tensile and compressive strength and is an excellent electrical insulator . Nylon is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. Fibres are made from melted plastic by passing it through fine holes in a spinneret. Jute is biodegradable, durable and strong.

Nylon is the most useful synthetic material with applications varying from daily life activities to industries. (c) wool Tensile Strength. Nylon is incapable of absorbing water. Nylon is incapable of absorbing water. President Andrew Jackson, champion of frontiersmen, helped advance the political rights of those who did not own property. Answer: (c) absorbs water Nylon is a synthetic fibre. Nylons were developed in the 1930s by a research team working for E.I. Define these. View NCERT Solutions for all chapters of Class 6. Which of these is not a property of articular cartilage? (a) leather Nylon is a very versatile fiber. What is Nylon. (d) Europe. Page No 31: Question 1: Name one fibre each that is: (a) smooth (b) shiny (c) fluffy Sericulture is the rearing of silkworm for the production of silk. The absorbed sweat then evaporates from the clothing and cools down the wearer in hot and humid weather. The applications of Nylon 6,6 is : > Because Nylon is a light material , it is used in parachutes . (b) jute Whereas dye bonds strongly to polyester fabric and are unaffected by UV radiation. (c) Fluffy: Wool is an example of a fluffy fibre. Notice that the two copolymer sub-units are held together by peptide bonds, the same kinds that join amino acids into proteins. It is used for everything from ladies' hosiery to tires. By about 1860, most white men without property were enfranchised. These tension levels are not standardized between manufacturers, and do not correlate to specific diameters. Jute grows best in areas that get ___________ (heavy/moderate/low) rainfall. However, the written records indicate that cotton clothing was made in India at least 3,000 years ago. All of these resins can be supplied pre colored or otherwise modified. Additionally, your shirts and slacks may be … Since air is a bad conductor of heat, wearing many layers of cotton clothing will keep you warm. (ii) Spinning: The fibres obtained by combing are spun into yarn by this process. (b) Egypt. Combing and spinning: The wool is then combed by a combing machine and spun into fibre. Jute is one of the cheapest natural fibres. Both nylon 6 and nylon 6.6 can provide good resistance to most chemicals but can be attacked by strong acids, alcohols and alkalis. The plastic is first melted at high temperature and then forced out through a device with many holes in it known as a spinneret. (I) Coal (ii) Air (iii) Water : A) Only (i) done clear. These solutions for Fibre To Fabric are extremely popular among Class 6 students for Science Fibre To Fabric Solutions come handy for quickly completing your homework and preparing for exams. The cocoons are collected and boiled in water to kill the silkworms. What advantages does cotton have over synthetic cloth? Wool, along with cotton and to a lesser extent nylon, is a fibre that absorbs moisture from the surrounding air to reach an equilibrium, which depends on the relative humidity of the environment. Thermoplastics can be heated and shaped over and over again while thermosetting plastics can only be heated and shaped once. (b) nylon There are often numbers associated with nylon plastics types such as 6, 66, 12 and 46. Nylon is a generic name for a family of synthetic polymers, more specifically, aliphatic or semi-aromatic polyamides in which at least 85% by weight of the amide-linkages (-CO-NH-) are attached directly to two aliphatic groups. Nylons are thermoplastics. Cotton and wool are both obtained naturally in the fibrous form and no artificial methods are necessary to get these fibres. The cocoons are then unwrapped to get silk fibre, which is then woven into fabric. (a) India. Why?
