Write the procedure of making cotton and juteyarn
Answers
Answer:
Explanation:
process of Making Cotton. From field to fabric, the process of making cotton transforms the raw fibers into threads, yarn and fabric in three steps: Preparation, Spinning, and Weaving. In America, this process was a tedious, labor-intensive activity done by hand until the 19th century.
In the selection process, raw jute bales are opened to find out any defect and to remove the defective portion from the mora by experienced workers. Raw jute bales are of two types i.e. 150 kg weight and 180 kg weight with or without top portion cutting. The bales are assorted according to end use like Hessiean weft, Sacking wrap, Sacking weft etc. After selection, jute bales are carried to softning section by workers called Gariwala and Bajawala.
Softning Process Jute:
In softning process jute morahs are made soft and pileable. Two methods are used for softning; use of softening machine and use of jute good spreader. Generally an emulsion plant with jute softner machine is used to lubricate and soften the bark and gummy raw jute. The emulsion plant consists of gear pump, motor, vat, jet sprayer, nozzles, emulsion tank and the jacket. In this softning process jute becomes soft and pileable and suitable for carding.
Carding:
Carding is a combining operation where jute reeds are splitted and extraneous matters are removed. Jute fibres are formed into ribbon called "sliver". There are three different carding sections:
(i) Breaker carding
(ii) Inner carding
(iii) Finisher carding
In the Breaker carding machine soften jute after piling is feed by hand in suitable weight. The machine by action with different rollers turns out raw jute in the form of jute sliver for finisher carding. In this process root cutting is necessary before feeding the material to the hand feed breaker carding machine.
Finisher carding machine make the sliver more uniform and regular in length and weight obtained from the Breaker carding machine.
Finisher carding machine is identical to the Breaker carding machine, having more pair of rollers, staves, pinning arrangement and speed.
Nearly 4 to 12 slivers obtained from Breaker carding machine is fed on this machine.
The material thus obtained is send to drawing section.
Drawing:
Drawing is a process for reducing sliver width and thickness by simultaneously mixing 4 to 6 sliver together. There are three types of Drawing Frame machine. In most mills 3 Drawing passages are used in Hessian and 2 Drawing passages are used in Sacking.
The slivers obtained from finisher carding machine is fed with four slivers on to the first drawing frame machine. The first drawing frame machines makes blending, equalizing the sliver and doubling two or more slivers, level and provide quality and color. This machines includes delivery roller, pressing roller, retaining roller, faller screw sliders, check spring, back spring, crimpling box etc..
In second drawing, the Second Drawing Frame machine obtain the sliver from the First drawing machine and use six slivers and deliveries per head. The Second Drawing machine makes more uniform sliver and reduce the jute into a suitable size for third drawing.
In the third drawing, the Third Drawing frame machine uses the sliver from second drawing. The Third Drawing machine is of high speed makes the sliver more crimpled.
Spinning:
Spinning is the process for producing yarn from sliver obtained from Third drawing. The jute spinning frame machine is fitted with slip draft zone and capable of producing quality yarns at high efficiency with auto-dofting arrangements also.
Procedure of making cotton and jute yarn:
Explanation:
- Yarn may be defined as the length of fibers that are interlocked with each other that helps in rope-making, textiles and used in industry. Cotton and jute are both blended in opening at opening and drawing stages,.
- Ring and rotor technology is used for the spun of the jute and cotton.
- Jute fibers and cotton can be chemically processed for strength and clothes.
- Blending is done with cotton at the different ratios to produce the fine yarn.
- One up and one down principle, the weft and warp blended yarns were spun.
