Yarn spinning starts with the transfer of the cotton bales from warehouse chosen by a special software to the blowing room feeder as a initial step of yarn spinning process. From this point onwards, cotton undergoes preparation processes like cleaning, opening and blending with the content of other bales. During this process, the fibers which are too short are extracted.

Warping is the process of transferring multiple yarns from individual yarn packages onto a single package assembly. Normally, yarns are collected in a sheet form where the yarns lie parallel to each other and in the same plane onto a beam, which is a cylindrical barrel with side flanges. This is known as beam warping. For ball warp denim, the yarns are brought together and condensed into a rope before being wound onto a relatively short cylindrical barrel that has no end flanges. In both cases, the supply yarn packages are placed on spindles, which are located in a framework called a creel.

Rope Dyeing is considered a superior dyeing technology where the dyeing uniformity achieved is better than other Indigo Dyeing technologies like Slasher Dyeing. However, Rope Dyeing is a also a more difficult dyeing technology. One needs to master its nitty gritties to get the best out of the system.

Traditional denim weaving had been done with the rapier looms and projectile looms for a long time. But with the development of the air jet weaving technology, the main flow of the denim weaving has been changed to Air Jet Loom due to its suitability to mass production.

In basic denim finishing, fabric arrives from weaving directly, without de-sizing, and is brushed to remove contamination, singed with flame to make the fabric smoother by reducing hairiness, padded with a simple recipe, passed over a pair of skew rolls to reduce fabric torque which causes skew movement and then dried.

Cutting is the major operation of the cutting room, when the spread fabric is cut into garment components. Of all the operations in the cutting room this is the most decisive, because once the fabric has been cut, very little can be done to rectify serious mistakes. Cutting can be done manually using powered knives or by computer-controlled system.

Seam and stitch are related to each other. Because stitch can not be made without seam and vice versa. Seam is the join between two or more plies of pieces of material. Seams are usually formed by sewing. Sewing is done by joining one or more threads or loops of threads with intralooping, interlooping or interlacing. Stitch is the unit of this sewing.

Denim washing is an aesthetic finish that is imparted to fabric to improve the softness and comfort of the fabric. In addition, the fabric achieves a different look such as a faded or worn-out appearance. It also enhances the appeal and to provide strength. The emphasis is on comfort and softness. Fashion trends favour the broken-in look and worn/faded seams that can only be achieved through garment processing. Much of the appeal of dry denim lies in the fact that with time the fabric will fade in a manner similar to that which artificially distressed denim attempts to replicate.

Sand blasting is recently a popular dry process & fashion. It is a mechanical process of creating fading affect/old looking affect on heavy garments like denim, canvas, twill, sometimes corduroy by the action of aluminum oxide which looks like sand. For this reason this process termed as “Sand blasting”.
