To produce superior quality of cotton yarn i.e., combed cotton yarn, we need to employ two more extra machines in our spinning line comparing to our conventional carded yarn manufacturing process. First of all, we need lap formers to produce regular laps and then comber machines to convert those laps into uniform slivers.

A commercial counting method, typically applicable for sewing thread which expresses thread’s fineness or thickness is denoted as ticket number. Ticket numbers are akin to the indirect counting system.
Draw Frame is the machine where the slivers are doubled or combined, blended & mixed, leveled and attenuated by transient through a series of pairs of rollers. In the drafting arrangement each pair of rollers move faster than the prior one.
Carding can be denoted as the process of lessening the entangled flocks of fibers to a filmy web by functioning the flocks between two narrowly spaced, comparatively moving surfaces covered with sharp-edged wire points.
An outlier bobbin is portrayed as a bobbin that surpasses one or a few resistance limits as for hairiness, imperfections, evenness, foreign fibers, and so forth. The explanations behind outliers are generation positions which are defective or shattered, mixed up of bobbins in the spinning procedure, contaminated crude material, and so on.
Blowroom is the place where the spinning preparation begins. It is the initial step of yarn manufacturing. Opening the fibers into small tufts, cleaning the trash out of the fibers including micro dust thoroughly and blending them homogenously with different grades of fibers altogether are the prime functions of blowroom.
Blowroom is the segment where the delivered compacted bales are turned into an even lap of a certain length. And this is done by opening them into small tufts first. Then, these fibers are cleaned with the help of beaters & mixed homogenously, or they are blended with different grades of bale. These are the operations that are usually carried out in a blowroom section.
To be successful in the spinning industry one must be alert on two factors which are the consistent quality of production and optimization of raw material expense. A judicious selection of cotton bales by testing, categorizing and blending homogeneously according to the characteristics of fiber for manufacturing precise good and consistent quality of yarn at minimum cost is said to be bale management.
Cotton is a natural cellulosic fiber that produces a variety of yarn due to its diversified end-use. On the basis of different end-use, cotton fiber is selected for spinning keeping in mind its different quality parameters.
Yarn can be defined as an extensive length of linked fibers formed by attenuation and twist which meets the demand of basic raw materials for the production of textiles, especially in knitting, weaving, sewing, embroidery as well as cable and cord making.
