of treatments that can be applied to afreshly woven fabric to enhance its

properties or to overcome itslimitation

It can be sub divided into four subcategory i.e

1) Mechanical finishes2) Filling finishes

3) Chemical finishes

4) Dyeing and printing

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.

Brushing and Shearing: This process

clips any short end of fibers or yarnssticking out of the fabric


4/16

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 .


5/16

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.


6/16

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

Tentering: This finish is given to afabric when their edges becomeuneven usually after dyeing.


7/16

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.


8/16

Chemical Finishing Mercerizing: In this process caustic

soda is added to give lustre to reduce

shrinkage. Anti-crease treatment: This process is

also known as crease proofing whereformaldehydes are mixed mostly with

cotton to form an insoluble resignwhich avoids crease.


9/16

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.


10/16

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.


11/16

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.


12/16

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

fibers are treated in such a way thatit retains water molecules.


13/16

Dyeing & Printing Raw stock dyeing: In this process the

stock of fibers is rotated in dye bath,then removed and dried.

Slub dying: In this process the woolis dyed after they have been combed.

Skeing dyeing.

Piece dyeing: In this process thesynthetic fibers are rolled in a dyewith a roller till it absorbs colour.


14/16

Dyeing & Printing Cross dyeing: In this process where

two different types of fibers are used,is mixed in two different dye of samecolor so that the fiber can absorb thedye.

Resist dyeing: this process is dividedinto two i.e. Tie dying and batik.

where the fabric is dyed to givedifferent types of design.


15/16

Dyeing & Printing Block Printing: In this process the

block made up of wool is cut into

inch thickness and then carved andstamped on the fabric.

Roller printing: This is done by theroller printers which contains several

copper cylinders or roller.
