Process of spinning production begins with blowing section where cotton bales reveal under certain conditions and temperature, are aired during 24 hours, and then cleared of alien subjects by special contaminations detector.
Cotton yarn comes from blowing section in the form of lumps of different sizes with impurities. In carding section each fiber is laid parallel to the length, simultaneously cleaned of impurities, black spots, short fibers and produce a strand. Therefore, carding process directly affects the quality of the yarn connection, it is considered one of the most important processes in the technology of spinning.
There are two technological processes of production of two kinds of yarn: card and comber. By production comber yarn, the cotton fiber passes additional combing process. The purpose of combing process is increasing of durability both other indicators and giving of shine to yarn that further provides production of a high-quality fabric, jersey and garments.
In drawing process unite fiber arrived from previous process and extending them, leading up to identical weight and length and making more smooth in parallel spread out lock - raise quality of yarn.
In roving process fiber made in drawing section, extend and it is thin braid for creation of the necessary thinness, then reel up on the reel.
Solving process at spinning mill where there is a transformation of cotton fiber into yarn, occurs in spinning section where the arrived lock extend, then lead up till the necessary thickness, for durability add raising or piles and reel up on the reel.
In winding section connect yarn breakage, reel up, clear by means of the special equipment and under the influence of physical strength necessary for following process winding on a cone or the reel, raise quality of a thread to level approaching for the further process in warping, twisting and packing sections.
DOUBLINGDoubling of yarn where two or more stands or ends of yarn are twisted together.The spun yarn is wound onto a bobbin using a doubling winding machine, and two or more of these bobbins are placed on doubling frame (doubling winding machine). The ends pass through a series of rollers and twisted together onto one bobbin using a spindle and flyer.High quality doubling depended on keeping the tension correct and feeding the produced thread evenly and tightly on a bobbin or flangeless paper tubes
The purpose of this operation is to combine two or more double fibers with a pair of fibers to obtain a rope. In most cases, in the non-conventional and mixed yarns, the double yarn is made in the direction opposite to the uniaxial direction. The yarns used for plying (single or twisted yarns) are less than 10 percent less than ordinary unit yarns are observed. In the ply yarn, the fibers behind the fibers in the components, when parallel to the axis of the rope, increase the internal fiber bonding sufficiently. Theoretically, in the Ply (trosse) yarns, the maximum permeability is achieved. Such a parallel state of felts contributes to the yarn strength. This fiber position also ensures maximum yarn gloss.
In packing section regulated weight, size, quantity and packing forms: pallets and boxes
