2. CARDING DEPARTMENT

• Carding, in textile production, a process of separating individual fibres, using a series of dividing and redividing steps, that causes many of the fibres to lie parallel to one another while also removing most of the remaining impurities.

Carding

3. PREPARATORY (DRAWING) DEPARTMENT

Preparatory

4. COMBER DEPARTMENT

• The comber is used in the production of medium, medium-fine and fine yarns. Within overall spinning process, the combing operation serves to improve the raw material.

• Yarn production is low, while generation of noil is high

• In Comber Department maintain (50-55 %) of RH for Cotton.

• In Comber Department maintain (50-60 %) of RH for Viscose.

• In Comber Department maintain (27-35 °C ) of TEMP for Cotton.

Comber

5. SIMPLEX DEPARTMENT

• Simplex is an intermediate process in which fibers are converted into low twist lea called roving. 

• The sliver which is taken from draw frame is thicker so it is not suitable for manufacturing of yarn.

• Its purpose is to prepare input package for next process.

• In Simplex department maintain (50-55 %) of RH in Plant.

Simplex

6. SPINNING DEPARTMENT

• Spinning is the process of taking textile fibers and filaments and making them into yarn. 

• Spinning involves many methods and different machines, depending on what kind of yarn is being made. 

• In Spinning Department maintain (50-60 %) of RH for Cotton.

• In Spinning Department maintain (50-60 %) of RH for Viscose.

• In Spinning Department maintain (55-60 %) of RH for Polyster.

• In Spinning Department maintain (27-35 °C ) of TEMP for Cotton.

7. AUTO CONER (WINDING) DEPARTMENT

• The Autoconer is highly automated. It winds spun cotton yarn from cops to cones, analysing it as it winds. 

• Any faults are detected by the machine and cut before the yarn is spliced back together.  

• In Winding Department maintain (60-65 %) of RH for Cotton.

• In Winding Department maintain (50-60 %) of RH for Viscose.

• In Winding Department maintain (55-60 %) of RH for Polyster.

• In Winding Department maintain (27-32 °C ) of TEMP for Cotton.

Autoconer

8. TFO DEPARTMENT

• The method of twisting two or more single yarns is called doubling or folding or ply twisting.

• Such yarns are designated as doubled yarn, folded yarn or plied yarn and the machines intended for the purpose are called doublers, ply-twisters or two-for-one (TFO) twisters.

• Two-For-One (TFO) is a two-stage process where the yarns are doubled and then twisted. 

• In TFO process two or more single yarns are twisted in order to enhance 

TFO

9. OE DEPARTMENT

• Open-end spinning is a technology for creating yarn without using a spindle. 

• The O.E. machines that are now in market boasts of many a basic needs like, longer length of machine, higher speeds, able to process coarser hank, fewer 

• Bigger supply of cans to open-end and bigger packages to weaving.

• In Weaving Department maintain (55-60 %) of RH.

• In Weaving Department maintain (30-35 °C ) of TEMP.

10. SIZING DEPARTMENT

• Sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakage during weaving. 

• Sizing is the most important operation in preparing warp yarn for weaving especially with cotton yarn.

• Relative Humidity (RH): 65% – 75%,

• Temperature: 26°C – 30°C (78°F – 86°F)

Sizing

11. WEAVING DEPARTMENT

• Weaving Department about loom mechanism .

• Loom is machine or device which is used to produce woven fabric. 

• It is the central point of whole process of cloth production

• It is a device used to weave cloth.

• In Weaving Department maintain (60-65 %) of RH for Cotton.

• In Weaving Department maintain (50-60 %) of RH for Viscose.

• In Weaving Department maintain (55-60 %) of RH for Polyster.

• In Weaving Department maintain (24-30 °C ) of TEMP for Cotton.

Weaving

12. DYEING DEPARTMENT

• Dyeing and printing processes are value added treatment for most textile materials.

• A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre.

Temperature:

• For cotton Pre-treatment: 98°C,
• For cotton Biopolishing: 55°C,
• Cotton Dyeing: 50 - 60°C,
• During Turquise: 80°C,
• During Isothermal: 80°C,
• Red special: 60°C,
• White dyeing: 80°C,
• For Polyester Dyeing: 130°C,
• For Cotton Soaping: 98°C,
• Temperature during Softening & fixing: 40°C,
• For Cotton hot wash: 70 – 90°C,
• For Cotton Acid wash: 50 – 60°C,

Dyeing

13.PRINTING DEPARTMENT

• In the best conditions the paper is designed to be stable in a 45 – 55% relative humidity (RH) at 72°F environment.

• Excess moisture deteriorates textile printing quality, reduces elasticity and tensile strength of certain fabrics, causes machine damage and slow down the production and drying process.

Printing

14.GARMENTS DEPARTMENT

• The garments department is responsible for converting fabric into finished clothing. It involves several key sections, each playing a crucial role in the production process.

• Garments maintain a relative humidity (RH) of 60% lower.
