Mechanical finishing These are physical finishing process
carried out on fabrics
Beetling: this process renders thefabric lustrous and soft as well asgiving it a firm, leathery feel.

Mechanical finishing Schereinerizing: This is a finish that
gives strength and luster to cotton.
Calendering: This finishin processsmooth out wrinkles, and gives asmooth, even surface to the fabric.
Sanforizing: Many fabric shrink after
firs wash. To overcome this effectthey are sanforized .

Mechanical finishing Crinkling: Also known as creping", in
which the material is passed betweentwo rollers to give a wavey crepeeffect.
Embossing: In this process a threedimensional pattern is embossed onthe fabric.
Glazing: The process produces a highsheen on the fabrics.

Mechanical finishing Moireing: This process produces a
shimmering, watery line effect onFabrics.
Napping: This produces a raisedeffect on the fabric and renders it softand warm

Filling Finishes Sizing & Dressing: This finish is
usually used on cotton, the sizingwears off after laundering, linen is notsized unless it is of poor quality.
Weighting: This process is mostlyosed for silk and wool yarn wheresalts are added to the dye. In thisprocess the silk/woolen fibers absorbsmetallic salt and Swell.

Chemical Finishing Mercerizing: In this process caustic
soda is added to give lustre to reduce

Chemical Finishing Dylanizing: this finish is given to wool
to avoid shrinkage.
Permanent press: This is the processin which a fabric is stitched intogarment and then given a heattreatment at 150 to 160 degree
centigrade to set the permanentpleads.

Chemical Finishing Fire proofing: this method is also
called as flame retardant finish wherethe fabric is treated with THPC(tetrakis-hydroxymethylphosphonium chloride)
Bleaching: bleaching results into purewhite fabric. This process is done ifany discoloration or staining occursduring prior manufacture.

Chemical Finishing Waterproofing: this finish is given to
the fabric by applying a thin film to
the fabric. Water-repelling treatment: In this
process the fibers are made waterrepellent by coating hydrophobic
substances or by chemical reaction.

Chemical Finishing Anti-moth treatment: this finish is
specially for wool where wool is
treated with chemicals such asfluorine compounds.
Anti-static treatment: This treatmentis for the synthetic fibers where the

Dyeing & Printing Raw stock dyeing: In this process the
stock of fibers is rotated in dye bath,then removed and dried.
