the processing of cotton into yarn (proses mengolah kapas sehingga jadi benang
Fruit / cotton flower (boll) that has been ripe ready to be picked from the tree. Picking can be done manually or by machine. If picking manually, then the leaves will not come plucked and the fruits are picked only that really is cooked. While the machine can not pick picked fruit. The types of cotton vary in each region, the fruit also varies in shape
Once picked from the tree, the cotton must be separated from the seeds. This process is commonly called 'ginning'. In this process the cotton is sucked into the tube to be inserted into the dryer to decrease the cotton moisture and the quality of the cotton fiber becomes better. Then the cotton will go through a cleanser that cleans leaves, stems and seeds that are still attached to cotton fibers. The cleaned cotton is compacted into a 1.5-meter (bales) ball that weighs up to 227 kg. The cotton bales are ready for further processing at the mills.
The next process is called Carding. Carding is a mechanical process to unblock fibers and straighten them to parallel one another. This process can also be used to create combined textiles (blends). In this process different types of fibers can be incorporated, eg cotton fibers mixed with silk fibers. Or used to combine several different fiber colors.
The next stage is Combing. Combing is the process of separating the shorter fibers, so the resulting yarn will be stronger and better. Actually this stage can be skipped, but if you want a better result then you should still go through this stage. Most high-end clothing brands wear either combed cotton or 'combed cotton' (though this term is rarely used in the textile industry). Fiber that has been through the process of carding & combingakan shaped long strand commonly called sliver (kerat).
The next process is Drawing or withdrawal phase. At this stage several slivers are combined to produce a very thick string of cotton fibers. This string is then called roving. Then two twisted rovings that produce the weight required for further processing into yarn. Furthermore, this merging and twisting or also called Slubbing, produces the desired thickness and yarn size. The whole process above is generally referred to as Spinning (Spinning). In more detail, there are many other steps that can be added in this spinning process, in accordance with the quality (size, thickness, color) of the yarn to be produced.
