Melamine Dishes, Electric Switch Board Caps PVC Pipes Polythene Bags Jute Sick Fabrics Woolen Fabrics Cotton Fabrics Nylon Yarn Rubber These things are familiar to us, we are always using them. These are all polymers. The word polymer comes from the two Greek words poly and meros. The word poly means many and the word porous means part. It means that a large thing is found in many small identical pairs. This is a polymer, so you can think of a layer of laher. A large chain is formed by attaching six parts of laher, and the chain is called polymer here in the language of chemistry. Polymers are made, they are called = (Monomer) The polythene bag we use is made from a monomer called "Ethylene" and similarly the PVC pipe we use (Pv) is a polymer made from a vinyl chloride. There is no such thing as a polymer being made from monamer, polymers can be made from more than one monamer, such as an electric switch. An electric switch is made of a polymer called bakelite. The fair is created From the two manamars named Maine and Formaldehyde we have seen in the beginning husband examples, some of them are found in nature. We call them polymers. Now they themselves are some of the examples given at the beginning of the ball, natural P jute, silk, cotton cloth, rubber - these are natural polymers. On the other hand melamine, regi PVC, polythene - these are not found in nature) are artificially made in industrial factories so they are synthetic polymers. 6.1.1 Polymerization process Polymers are made from mannamar through a specific process. The process by which polymers are formed by attaching mantras is called polymerization process. Usually polymerUnderstandably, there can be no more than two manameras in the footsteps. | If there are three manomaras, then we can write if the substance produced has three manomaras. | 1 manamera 1 manoeh. 1 manamera → manomara manemara manomara bya. However, because the high pressure method is not easy, the method is not very popular at present. Now Tate Taemra knows that one of our five basic needs is not to stop. Coughing is an important part of modern civilization. Do you know or copy? I can write like this. 1 Manamema: - 1 Manamera → Manamema: Manamera or we can write it in another way (Manamera), Manomera Manomara (Manamera), if we want to make a polymer with n number of Manamera, then polymerization proki. It can be shown in the following ways: Manamar → Manamar) n. Or n manamemar ⇒ (monomar) We are talking about polythene, do you know how polythene is made? Polythene is obtained by heating ethylene gas at 1000-1200 atmospheres at a temperature of 2000 C. However, in order to accelerate polymerization, oxygen gas is used as a catalyst (high temperature and pressure ri (ethylene), polythene (O, reactant). Or, n CH = CH) (high temperature and pressure (), lecturer) - CH - CH - In trichloride. Polythene is made at atmospheric pressure using an influencer called (TIC1). 6.2 Fiber or yarn. Protects us from the cold and we make beautiful clothes with clothes. | After bringing all the books from where he is, from A to A to NA, we have to say that the non-native material is the only thing that can be used in the art. | Warak ra etc. are made from different materials. It refers to the eighties used in the work, except for the yarn and the cotton, which are found in nature in linen silk, wool, sic asbestos, etc. We call salulu a natural fiber. On the other hand, polyester cans, zen nines, etc., which are made artificially by chemical reactions of various substances, are among the artificial and natural ones. Cotton, jute, etc. are also found in plants, so they are derived from plants. The convection capacity is high. Yarn is made from cotton ash. There are two types of essential fiber in natural taxes according to the source. Cotton is used for making cotton cloth. On the other hand, silk and fur are found in animals. That is why they are called animal fibers. Again metal fibers are found in natural mines. So these are called mineral theories. On the other hand, synthetic fibers are of two types. Cellulose fibers and non-cellulose fibers are known to be a kind of fine-grained substance, which is used to make plant and animal cells. Synthetic fibers that are not made from cellulose but are chemically reacted with other substances are not cellulose fibers. Nylon, polyester, polypropylene, den - these = non cellulose synthetic fibers. 6.2.1 The properties and use of fiber depends on whether a garment is comfortable or not. So let's take a look at the different properties of natural and synthetic fibers. On a hot day, we feel comfortable to wear cotton clothes because the heat of cotton is pure yarn. Under the microscope (Figure 7.01) the cotton thread looks a lot like a tube. In the first case, all the matter is filled with a substance called lumen. Goes later and flattens the tubular akuti slowly.| Takes the form of a ribbon in a marana. According to this ribbon, cotton ashes. B is durable. Apparently cotton is not wool. However, during the making of moisturizing (mosuran cloth or cloth), the parts of this mixture blend nicely with each other, but there is not much damage in contact with other acids. Can be made single and shiny by means of yarn. If the yarn is dyed, it becomes ripe. Figure 6.91. Silk or silk garments are used to make luxurious garments. Silk fibers are used to make luxurious garments. The main quality of silk is beauty, more than three hundred colors of silk are available. Silk is made up of a type of protein called fibroi. Silk is called the sock queen in natural animal fibers and for its various qualities, silk is called tar rani. Luka but much warmer and in very few places. Sik clothes can be kept. Wool Wool is the first garment we think of to protect us from the cold. Woolen garments are widely used as winter clothing as they are heat conductors. Elasticity, wrinkle resistance, color retention - these are the characteristics of wool. There is space between these fibers where air can be trapped.
