Weaving is nothing but the interlacement of two threads with the help of a weaving machine known as loom (Handloom and Power loom,).
The two threads interlaced each other is known as (1) Longitudinal (2) Horizontal.
Longitudinal threads called as warp yarn and Horizontal threads called as weft yarn.
These two threads are interlaced in such a manner that they cross up and down with each other with some designs say plain or twill etc.
The yarn (threads ) used in weaving cloth (fabric) are produced in two different process (a) SPINNING. (b) TEXTURISING (Polyester).
SPINNING:-
The procedure of transferring fiber into yarn is known as SPINNING. In this machine process various levels are added to convert fiber (cotton , wool etc.)into yarn and process it further for textile products. This transformation goes through various stages such as;
1) Blow room.
2) Carding .
3) Combining.
4) Drawing.
5) Roving. For fine count , a process of combing is carried out.
6) Cone winding.
7) For fine count Combing .
BLOW ROOM:-
In this section of spinning mill blow room consist of machinary which is used for opening bales of fibers and removing unwanted material present in the fiber. Here cluster of cotton is changed into miniature material. Simply in the blow room section, the compressed bails of cotton fibers are opened and blended/mixed according to particular length of fibers to form a specific size length. The cleaning of fiber is called GINNIG.
GINNIG PROCESS IN BLOW ROOM:-
The opened cotton fiber here first spread and made loosened then after wards it processed to remove the natural impurities ( dust, seed parts,natural oil etc.) present in it.
CARDING:-
It is known as the heart of spinning. This is a process of separating individual fibers, using a series of dividing and redividing step, that causes many of fibers to lie parallel to one another, while also removing most of the remaining impurities. Carding may be done by hand, using hand carders (pinned wooden paddels that are not unlike steel dog brushes) or drum carders (in which washed wool, fleece or other materials are fed through one or more pinned rollers) to prepare the fiber for spinning or other fabric (cloth making activities).
Cotton, wool waste silk , other than fibrous plant materials and animals fur and hair and artificial staple fibers are subjected to carding. Carding produces a thin sheet of uniform thickness that is then condensed to form a thick continuous untwisted strand called Sliver . When very fine yarn are desired, Carding is followed by combing process . Combing is process that removes short fibers ,leaving a sliver composed entirely of long fibers all laid parallel and smoother and more lustrous than the uncombed type. Carded and combed sliver is then spun.
COMBINING PROCESS:-
As the yarn is arranged in a parallel manner. It is straightened again in stage of combining. On the other hand, the left shorter fiber will be substracted completely from the longer staple fiber. This will result in stronger and smoother. Staple fabrics having higher demand in the market.

DRAW FRAME (DRAFTING OR DRAWING).
This is a device which drafting and drawing is carried out. Doubling is the application of feeding several intermediate strand into lessen fiber laps (sheet) to sliver. In process of making sliver arranging the loose assemblage of fiber by passing it through a series of rollers thus straightening the individual fibers and making them more Parallel. Each pair of rollers spun faster than the privious one. Drawing reduces the softness of fibers to a firm uniform strand of usable size.
In the production of man-made fibers, drawing is a stretched process applied to the fiber in the plastic stage increasing orientation and reducing size.
ROVING/RING FRAME:-
The yarn produced is processed into a speed frame to attain roving yarn. This is the initial step where a twist is inserted for giving held to the fibers in the yarn. The roving yarn is of a little larger (thicker) diameter as compared to the final yarn . Similarly, ring frame are used to produced finished yarn. The yarn resulted in having a good amount of strength through these ring frame and was made as per the requirement of the thickness (i.e. count) meanwhile it is twisted also in these ring frames
TWISTING:-
Twisting in yarn and rope production, it is a process that binds fibers or yarns together in a continuous strand, accomplished in spinning. The direction of twist may to the right described as Z twist , or to the left described as S twist.
CONE WINDING MACHINE:-
It is a simple process in function linked between the last stage of yarn manufacturing of yarn. In this the final yarn (ready yarn,) is wounded on spools or paper cone. Then after checking for its quality and count , it is packed either in box or jute bags or plastic bags in bundles.
The above manufactured yarn is grey in condition and if we required to colored fabrics, then it is given for further process such as scouring & dyeing.
If the yarn is to be produced for fine count and for a good and lustrous fabric, then it is given a process called combing.
COMBING:-
This process removes the projected and extra fibers in the yarn , which gives a smooth feeling. After combing process , the yarn is wounded on paper or plastic tube as per requirement of market on winding machine. The ready wounded yarn are then packed after checking in bundles and bags.
