Textiles Basic Processes
1. Simple Textile Production Process
Spinning : Process or process used into production of yarns or filaments. The process involves in the ring spinning yarn
formation are
•Funtion : The removal of unwanted non-lint or trash from a fiber mix
•Section: BlowRoom (manual / automatic)
Plucking •UoM : Lab
•Function : Straightens, parallels, and cleans cotton fiber
•Section : Carding
Carding •UoM : Sliver (Drum)
•Function : Silver are blended, parallel of fiber, reduce thickness of sliver by drafting,
•Section : Drawing
Drawing •UoM : Roving Sliver (Drum)
•Function : Remove short length Fiber. (Pre comber , Comber, then Post Comber)
•Section : Comber
Comber •UoM : Comber roll
•Function : reduce the thickness of sliver. Pre process of Ring Spinning Process.
•Section : Roving
Simplex •UoM : Roving Bobbin
•Function : True twist is inserted into parallel fibers by means of a rotating spindle.
•Section : Ring Frame
Ring •UoM : Ring bobbin
•Function : Transfer yarn from multi ring bobbin to One cone of Standardized weight.
•Section : coner (Auto / Manual)
•UoM : Cones > Bags / Cartons

2. Simple Textile Production Process
Weaving: The process of interlacing at least two yarns at right angles to form a fabric.
•Functional : transfer yarn (cones) into Warper's Beam. Sectional Warping is used for Yarn Dyed Fabrication.
•Section :Warping
•UoM : Warper's Beam
Warping
•Function : Before weaving to protect the yarns form abrasion in the healds and reed against each other, apply
starch mainly, a chemical treatment to mutliple (calculated) warper's beams.
•Section : Sizing
•UoM : Sizer's Beam
Sizing •Supporting : Sizing recipe
•Function : in the process of drawing the warp’s thread passes through the eye of heald wire and dent of reed
according weave type / pattern. In case ot running pattern Knotting process is used from Sizer's beams to Loom
•Section : Drawing In (manual / Automatic)
Drawing In •UoM : Weaver's Beam
•Function : Intersection of Warp and Weft yarn in loom for the formation of fabric.
•Section :Loom shed
•UoM : Cloth Roll
Weaving •Support : Reed of esp count. Weft yarn.
•Function : Inspection fabric, mending if required. Also assign grading to fabric.
•Section : Inpsection hall (manual / automatic)
•UoM : Pieces , with identifucation tag. *Loom number, weaver,* roll number, * grade,*length (yrd/meter),
Inspection & *width (inches/cms),
Mending •Support : Packing on the bases packing instruction in UoM *Roll, *Bale, *pilates.

3. Simple Textile Production Process
Processing: the Yarn Fabric or Garment treated combination process of Chemical and / or Mechanical process which change
physical or chemical state of Textiles (Yarn, Fabric, Garment). The sub-processes are;
Pretreatment: Preparation process (es) of textiles.
•Function : a mechnical process to remove of protruding fibers by direct flame or by infrared radiation or by burring against hot
plate
•Section : Pretreatment
•UoM : in length mtr / yrd.
Singeing •support : machine & process paramenter. A-frame/trolley to hold material
•Function : removal of size (starch) from the fabric (usually in warp) during sizing process in weaving.
•Section : Pretreatment
•UoM : in length mtr / yrd.
Desizing •support : Desizing Recipe, machine & process paramenter. A-frame/trolley to hold material
•Function : the treatment of textile materials of aqueous or other solution in order to remove the natural fats, waxes, proteins and
other constituents, as well as dirt, oil and other impurities (by sponification).
•Section : Prtreatment > Bleaching
•UoM : in length mtr / yrd.
Scouring •support : Scouring Recipe, machine & process paramenter. A-frame/trolley to hold material
•Functional : a process for improving the whiteness if textile material with or without the removal of natural coloring matters
and/or extraneous substances.
•Section : Prtreatment > Bleaching
•UoM : in length mtr / yrd.
Bleaching •support : Bleaching Recipe, machine & process paramenter. A-frame/trolley to hold material
•Function : the treatment of cellulosic textile in yarn or fabric form with a concentrated solution of caustic alkali where by the fiber
are swollen, the strength and dye affinity of the material are increased
•Section : Prtreatment > Bleaching
•UoM : in length mtr / yrd.
Mercerizing •support : Mercerizing Recipe, machine & process paramenter. A-frame/trolley to hold material

4. Simple Textile Production Process
Dyeing: the application and fixing of a dye and substrate normally even distribution throughout the substrate,
Printing: the production of design or motif on a substrate by application of a treatment of colorant or other reagent usually in a
paste or ink in a predetermined pattern.
Finish a process physical/chemical applied to a substrate to produce a desired effect.
Process includes;
Fabric Processing

6. Simple Textile Production Process
In the Textile Processing Flow, the inspection process is not shown it does not means that it is not necessary, it is the most
important factor. The role of Inspection is very important at each and every stage of process from Fiber to Dispatch. So
inspection may online or offline, both are required and according to the process requirement. The role of Quality Assurance and
Quality Control is important to do such tasks.,
