Fibre To Fabric. The fabric usually used in the clothes we wear is produced through two processes: the “spinning process,” where raw cotton is turned into thread, and the “weaving process,” where the thread is woven into fabric. An elastic stretchy yarn is needed for knitting. This process is known as carding. Actually good quality fabric production involves dyeing at the yarn stage, as the colours will not fade much. The cotton fibres are then converted into rope-like loose strands. Finally, the fabrics are produced. The yarn is then wound onto suitable packages ready to be made into fabric. Once any desired finishes have dried, the fabric is … These often take the name from the fibre in which they are spun. You can find more books on textiles here. The process of removing seeds from cotton is called ginning. Aside from looking pretty and feeling nice, the orange yarn has an additional benefit: thanks to nanotechnology, the material still contains essential oils and vitamin C that are present in the citrus fruit peel. Yarns and Fabric Fibres are then spun into yarns and threads. Non-Woven Fabric:It is produced by mixing fibers and making into the form of a thick layer of a web of a width corresponding to the desired width of the fabric. Desizing process involves removing the sizing (added to the yarn) by washing the fabric with diluted acid or by enzyme treatment. Threads can now be woven or knitted into fabric. The biodegradable yarn can be spun with any type of existing yarn. Carding – is a process where the tufts of fibres are converted into individual fiber forms. One such example is given. Paheli wants to present her friend a gift made of plant-fibre. To make fabrics, all these fibres are first converted into yarns. Fibers are the building block of a fabric and they are generated or produced by many means – man-made fibers /synthetic fibers and natural fibers are all made following many practices including sericulture for silk, cattle rearing for wool, various chemical processes etc. Question: What are looms? Use of charkha was popularised by Mahatma Gandhi as part of the Independence movement. Chemical finishes can be applied to make the fabric washable by coating it with a resin film. Different methods like Reactive, Pigment, Textiles : Fiber to Fabric : Bernard P Corbman 1983. Combing is a process in which the short fibers are removed. (iii) All plant have fibres in their body. Fabric is made from yarn by the process of weaving or knitting. Conventional shuttle looms, rapier looms, and jacquard loom is commonly used. Weaving: Weaving involves making fabric by arranging two sets of yarn. In this video of Fibre to Fabric, we will understand the beautiful science behind the process of making Fibres and turning them into Fabrics. These fibres are also called as the manmade fibres. It is very important to individualize fibers in the card to make them able to convert in yarn in the later processes. _____ and _____ are the ways used to make different kinds of fabrics. (c) All these yarns are first converted into fibres. Cellulose is an important structural component of cell walls in green plants. Air texturing, is another similar process that uses high velocity air instead of heat. Spinning cotton yarn. Ginned cotton is compressed to form bales. Spinning is an indispensable preliminary to weaving cloth from those fibres that do not have extreme length. Fibres are thin and small and cannot be made into a fabric directly. Fiber at this point is an entangled mass of fibers – they are passed through a carding machine so that the fibers are cleaned from all impurities and a continuous web/sliver of fiber is produced – the fibers are arranged in a parallel manner. Here the fibres are notonly twisted but also pulled out or drawn.You can try spinning and making a yarn yourself. Type of Loom is a very important component in the formation of the woven fabric – the whole appearance of the fabric is changed in the loom.
