Process control in blowroom:
The spinning process is the collective result of several processes. Due to the number of steps involved in this process, its control is complex and lengthy. The process control of the spinning department ranges from bale opening to yarn packing. In order to control the process in the bloom room, the bales of raw cotton should be opened and kept open for a certain period of time. In the case of hand stack mixing, the size of the cotton pieces and the size of the stack should be determined. If there is a bale plucker, the bales should be arranged evenly. During hand stack mixing, cotton should be fed vertically from one side to the bale opener during feeding. https://bdfabric.com/standard-commercial-fabrics-and-fabric-specifications/
So that the side wall of the feed lattice does not come up. Blowroom machinery plays a role in installation and process control, it should be such that the cotton progresses from coarse beating to fine beating in the blowroom. The machine’s speed, setting, fan speed, etc. should be determined according to certain rules. Feed-regulating machines at various stages of the blowroom should be kept operational. If the chute method is in blowroom, air pressure and if there is a sketcher, the calendar roller pressure should be determined according to the type of fiber and maintained, moreover, the R.H% of the blowroom should be fixed.

In the carding process first, there should be evenness of feed material i.e. lap sheet. The relative setting and speed of the carding parts are important factors. The amount of wastage, and condition of evenness, greatly affect the production and quality of carding. The amount of waste elimination can be reduced or increased by changing the settings of the taker in-mat knife, cylinder-under casing, cylinder flat, cylinder-bake plate, and cylinder percentage plate within certain limits. To the extent that wastage needs to be removed, this setting should be maintained.
The speed of the carding machine is an important regulator, the fact is that “Lower speed better carding and higher speed inferior carding” should determine the carding speed according to the operation. Carding card clothing should always be kept in working order. This requires necessary cleaning, stripping, setting, warping, and grinding. R.H% of card room should always be kept correct. The filter room should be properly sized and properly cleaned.

Auto-stop mechanisms in the feeding system should always be kept operational during the drawing process. Machine speed, roller settings, and cut roller hardness must be maintained to a certain extent. Moreover, the temperature and relative humidity in the drawing frame room should be maintained properly.
Process control in roving:
Spinning process control in blowroom carding drawing roving ring. Drain sliver regularity in the roving process and auto stop in feeding should be checked and maintained. Roller set, flyer speed, twist, tempering shape of the bobbin, and roving stretching should be determined and maintained. Temperature and humidity should be maintained properly.
Process control in ring frame:
In the ring frame process feed material, check, and feeding system should be properly determined. Draft, twist, spindle speed, ring traveler, drafting zone pressure, etc. should be maintained according to fiber type and count. Room temperature and humidity should be maintained properly. Cleaning measures are very important. The cleaner the section, the higher quality yarn will be produced and the production level will also increase.
