Nylon: It is used to make stocking, seat belts, ropes, tents, toothbrushes, sleeping bags, curtains and parachutes etc. Plastics containers are used as storage devices because it won’t get reacted with the substances which it stores. Plastics ,paints ,medicines,cement, fertilizers,synthetic fibres are some of the man made materials. The only thing that prevents it from being used more, especially in the manufacture of vehicles, is its high cost. As for clothing, it is often used in the manufacture of socks, scarves and hats. It is quite elastic; Is very strong, it resists very well to insects, animals, fungi and many chemicals. The PET bottles we use are commonly made up of synthetic polymer called as polyethylene terephthalate. When the synthetic fibres are heated in the absence of oxygen then fibres start to decompose and carbon fibres are formed. What are natural fibres? It is stronger than steel, like a modern armor, but lighter and more flexible than steel. With technology, scientists have discovered new synthetic routes of joining small molecules into large polyester chains with the correct properties for particular uses. Nylon . Answer: Synthetic fibres are man made fibre. Some of the most common synthetic materials are nylon, polyester, carbon fiber, rayon and spandex or lycra. It has very sought after properties because it is made of fibers that are strongly pressed with each other. The synthetic fibres are made up of very large units called polymers. ���>K�`�zj{\��O�V���4ٹ��c=��4����|N�����_K����x�6bK�v�v���@��ç�k�gӇ�e�'m>��un�y:�}��=qؕ�{�?W�I�n��-��X�as��}��L�Is��ϨsO>L���j �����I��dg#d�9�81|�]���9|�7A�5�@��>� �������av�g �8�,qp8�(�t ��>u�5�s��|٫�ٴ���ZKÈ��}- �\�xV�0���v}����:L�L�m�x�=�1n���昃E�ILD/�|Dw�T1���:��l�1g}:�5������q��ut���X@�C2q\���ʉ���Ic9��ގ/ʇ9��y|�6���!�s���p�� ��������}vN��~���v��%��υ�A߳����c���\}���3~-�lDx^W�z0�~��G�;ù��ъW�t��5eMG��0�Z㹉/�V8|ͧ�0�?����_���Z�O��/ endobj Answer: it is obtained from a natural source. 1. 2. Several vegetable fibres were also used by prehistoric peoples. It does not melt and only decomposes at a temperature higher than 450 ° C; The cold does not damage it, can survive temperatures up to -196 ° C. It resists attacks of different chemicals and moisture does not harm it. For its elasticity and strength it is used in many articles of clothing, especially in the sports field. Retrieved from explainthatstuff.com. By using this website or by closing this dialog you agree with the conditions described, Types of Synthetic Materials and Features. It is a very strong material, but relatively light. In some it is linear, whereas in others it is cross-linked. Synthetic textiles like terylene and nylon, cement, glass, plastics, dyes, soap, detergents, fertilizers, insecticides and pesticides are some man-made materials which are commonly used. But technology has made it possible to turn renewable resources into plastics and synthetic gums. Retrieved from books.google.com. to highly specialized uses in aircrafts, ships, spacecrafts, healthcare, etc. 1.1 INTRODUCTION As we all know we use a number of materials in our daily life. <>/ExtGState<>>>/BBox[ 0 0 2222.28 2667.83]/Matrix[ 0.032 0 0 0.027 0 0]/Filter/FlateDecode/Length 71>>stream 1 0 obj Synthetic materials make up almost half of all materials that are used in all fields of textile technology. TERYLENE Depending upon the types of chemicals used for manufacturing synthetic fibres, they are THERMOPLASTICS named as Rayon, Nylon, Polyester and … Some of the most common features are waterproof materials, stretchable materials and stain resistant parts. At that time it was used to manufacture tires, tents, ponchos and other military supplies. Polymers are not the only material capable of self repair, but they are the most efficient. 5)acrylic fibres are used to make blankets and shawls A fibre is a natural or artificial thread which bears higher tensile strength and is very strong. endobj We use Nylon, Polyester, Acrylic and rayon fibers in our daily life. The first fully synthetic fibre was glass. Manufacturing Technology: Materials, Processes, and Equipment (2011). Worldwide fiber production reached 90.6 million tons (90.6 × 10 6 t) in 2015 [6] as sketched in Fig. These materials can be sensitive to changes in temperature, humidity, pH, light intensity and magnetic and electronic fields. That why plastics containers are used as storing devices.

In many occasions combinations of polyester and natural fibers are created to obtain different results. Answer: Acrylic. It has many commercial applications in synthetic fibers, such as floor coverings and rubber reinforcements; It is also used to model automobile parts, especially the engine compartment, and in electrical equipment, in dental brushes, carpets, nylon stockings and clothing fabrics. Depending upon the types of chemicals used for manufacturing synthetic fibres, they are named as Rayon, Nylon, Polyester and Acrylic. However, most people do not even know what a polymer is, or just how widespread they are around us.Polymers are formed from hydrocarbons, hydrocarbon derivatives, or sometimes from silicon. Synthetic polymers are very stable. Can you add some more to this list? When auto repair technology is added to this equation, the results could have important uses in many industries. Synthetic gums and gel can adjust their shape in response to external stimuli; This means that they respond to changes in the environment. Retrieved from reference.com. 1) synthetic fibre like nylon is used to make parschutes and also used for rock climbing.2)synthetic fibres like rayon is used to make bed sheets and carpets.3)symthetic fibres are also used to make umbrella.4)it is used to make dress materials. Polyester is a synthetic polymer fiber produced from fossil fuel and is used to make clothing, blankets, carpets, and other fabrics. Ans – Natural fibres and synthetic fibres. 15 Plastic is used for making a large variety of articles of daily use and these articles are very attractive. Synthetic fibres are made by human beings through artificial methods i.e., rayon, nylon, etc. There are different methods for making these materials, but the most common is the melt turning. Like synthetic fibres, plastic is also a _____ . Accepts the color very well, has no problems when being washed and is usually hypo allergenic. They involve very complicated designs and are difficult to manufacture, but when repaired they are more durable than other polymers.
