Answer ONE of the following questions: 1. How does the ideology of the Soviet Union mold the conditions in the camp? 2. What survival techniques did one character in the novel practice to survive the camp and how do those actions and thoughts relate to the politics; ideology; and history of the Soviet Union?
Machine needles come in various shapes and sizes and should be used on individual machines, stitch types, threads and fabrics. The two basic classes of needle points are Round and Cutting points needles. Round points needles includes slim set points which are used for blind stitches and for fine densely woven fabrics, set cloth points, heavy set point used especially for button sewing machines, light ball points used for sensitive fabrics such as knits, medium ball point and heavy ball points. Cutting points needles which are used sewing leather and films or coated and laminated textiles are left cutting points and spear points. (Eberle et al, 2004) SEWING THREAD The threads are used to form stitches on fabrics. They are made from either natural or synthetic fibres or both and are chosen according to suitability for sewing in relation to uniform thickness, smoothness, elasticity and strength. Cotton is used to make natural fibre threads and nylon is used to make synthetic fibre threads. Sewing threads undergo the same process of production with yarns. The fibres are carded, combed, drawn and spun into yarns which in turn are twisted into sewing threads. Sewing threads can either be Z or S twist. The fibre on the surface of a Z twisted thread are faced to the right when the thread is held vertically while the fibre on the surface of an S twisted fabric are faced to the left when the thread is held vertically. The properties of threads are; colours, diameter, finish, size, twist and cord content. Characteristics of sewing thread are colours, fastness, flexibility, elongation, strength, shrinkage, twist balance, etc. FEED MECHANISM It is essential to consider the issues of feed mechanism in the process of product development. Feed mechanism is a process used in a sewing machine to join fabrics together whereby mechanism feeds the fabrics past the needle to achieve good fit, style appearance and performance. The sewing machine feed system are drop feed, differential feed, variable top and bottom feed (before and behind the needle), compound feed, alternating compound feed, puller feed (roller feed) and clamp feed(jig). Feed mechanism is made up of three sewing machine parts; presser foot, throat plate and feed dog. Material feed is achieved by the feed dog which contains several rows of serrated teeth. The feed dog is moved upwards and forwards through slits in the throat plate to engage with the other side of the material being sewn and to advance it by a distance of one stitch length. Contact between feed dog and material is is controlled by the spring-loaded presser foot. The feed dog is then lowered and moved back to its starting position. (Eberle et al, 2004, p.162)>GET ANSWER
