Qing asked the spinning machine clear, steel, and, coarse, fine, how to understand

Clear steel and coarse and fine this understanding:

"Clear steel and coarse and fine" is the cotton spinning mill in the ring spinning (carding) process of the traditional five key production processes, or five essential key processing equipment, is the cotton spinning mill on the "flower clearing ", "carding", "and", "and", "roving", "spinning" the Commonly referred to as.

Clear - clearing, refers to the open clearing process, that is, from the ginning plant to the cotton mill for the raw cotton for the compression of the bale and contains impurities. Cotton spinning mill of the first process is to open the raw cotton and remove a portion of the larger and heavier impurities, in accordance with the requirements of different yarn varieties spun by the mixing of cotton into a fixed length and weight of the cotton rolls, for the next process. Its role in general terms can not be separated from the grabbing, feeding, transportation, opening, removing impurities, mixing, uniformity and so on. Open and clear the cotton process is usually a set of electromechanical combination of open and clear the cotton joint equipment to complete the combination of this open and clear the cotton equipment has a lot of series, stand-alone model is also a lot of different countries and different manufacturers of equipment also varies greatly, due to the raw materials and products and other requirements of the different equipment selection and configuration also varies.

Steel - carding (also commonly known as "steel wire"), refers to the carding process, cotton mills are usually accustomed to call the card for the steel wire machine or steel wire car, because of its main combing parts of the rollers, tin, dawg, cover are covered with a complex of serrated spines or steel wire needle cloth and the name. Name. Carding machine or wire machine to the cotton block, cotton bunch mixed combing into single fibers, and further removal of raw cotton in the cotton seeds, leaf debris, cotton knots and short fibers. The previous process of the cotton rolls stretching made of regular circles placed in the sliver barrel sliver (commonly known as "sliver"), for the next process.

Usually "clean", "steel" or "clean steel" process or equipment should include these equipment supporting the dust filtering system and electrical control system.

And - and the strip, refers to the strip process, that is, 6 to 8 (a model can be 10) of the carded raw cotton draw and merge, so that the fiber material to get further mixing, straightening, parallel, and to improve the unevenness of the sliver. In addition to cotton and chemical fiber blends using three and strip, usually two and strip is commonly used, the last and strip machine down the sliver is commonly known as ripe strip.

Coarse - roving, refers to the "roving" process, that is, the cooked strips after stretching to make the fibers further straighten parallel to a small amount of twisting back, spun into a slightly strong roving, regular layer-by-layer winding to the barrel tube, shaped into a truncated conical at both ends of the "roving". "roving", easy to apply to the next spinning process.

Fine - fine yarn, refers to the "fine" process, that is, the roving through the drafting, twisting and spinning into a certain number of special (number of counts) uniform yarn with a certain strength, and winding to the tube.

(In addition, the spinning process is generally followed by "tube shake into" and other production processes, that is, "winding", "shaking", "yarn packing". (short for "yarn packing").

With the continuous development of textile technology to high-quality, high-yield, automation, continuous direction, the above five traditional processes and process equipment have different new combinations or new joint:

Open and clear the cotton process and carding process through the carding pipeline and electromechanical automation system into a joint production line, that is, from the raw cotton to open and clear the cotton does not need to be processed into a roll of cotton, directly with the cotton pipeline In the form of cotton fluff evenly distributed to multiple carding machines on the automatic cotton box continuous production, known as the "clear carding union" or "clear steel union".

The new highly automated textile production line also includes: and coarse union (parallel roving machine), coarse and fine union (coarse and fine yarn union) and fine complexion union (fine yarn winding machine) and so on. But all changes are not the same, we can still distinguish from the "clear, steel, and, coarse, fine".
