Basic Tex le Wet-Processing Terms!

 Wet Processing
o It is a processing stage where tex le substrates are treated with colorants or
chemical.
 Singeing
o Singeing is the process of removing the hairs of fabrics or fibers.
 Gas Singeing
o The process of singeing fabric over burning flame
 Roller Singeing
o The process of singeing fabric over heated rotary copper cylinders.
 Hot Plate Singeing
o The process of singeing over a hot plate
 Desizing
o Desizing is the process of removing the starch or size the covering of warp yarn
using enzyme.
 Scouring
o In this process, the fabric is treated with alkali (NaOH, Na2CO3, etc.) to remove
fats, wax and oils so that absorbency increases.
 Bleaching
o Bleaching is the process of removing the natural color of fiber to make white and
lustrous.
 Mercerizing
o Mercerizing is the process to improve the luster, hand feel and other proper es of
co on by using a strong caus c alkaline solu on.
 Dye
o Dye is a coloring compound which adds color to the tex le substrate.
 Natural Dye
o The dye which are obtained from natural resources.
 Synthe c Dye
o Dyes derived from organic or inorganic compounds.
 Bale Dyeing
o The process in which tex le substrate are dyed at the fiber stage.
 Yarn Dyeing
o The process in which tex le substrate are dyed at yarn stage.
 Beam Dyeing
o In the method warp is dyed prior to weaving. It is wound onto a perforated beam
and the dye is forced through the perfora on thereby satura ng the yarn with
color.
 Chain Dyeing
o This is used when yarn or clothe are low in tensile strength. Several cuts or pieces
of cloth are tacked end-to-end and run through in a con nuous chain in the dye
color. This method affords high produc on.
 Jig Dyeing
o This is done in a jig, vat, back or vessel in an open forma on of the goods. The
fabric goes from on roller to another through a deep dye bath un l the desired
stage is achieved.
 Raw Stock Dyeing
o Dyeing of fiber stock precedes spinning of the yarn. Dyeing follows the degreasing
of wool fibers and drying of stock.
 Solu on Dyeing
o Also called dope dyeing or spun dyeing; the pigment color is bonded-in the
solu on and is picked up as the filaments are being formed in the liquor. The colors
are bright, clear, clean and fast.
 A er Wash
o To remove the excess chemical substance the fabric is washed.
 Mercerizing
o The process in which fabric is treated with 20-22% NaOH for 2-3 minutes at room
temperature. During merceriza on yarn becomes swollen which makes the fiber
cylindrical in cross-sec on. So, which gives a smooth reflec on of light and makes
the surface more lustrous.
 Wet Pick-up
o The amount of dye picked-up / absorbed by the fabric during applica on process.
 Take-up/ Add-on
o The amount of dye / chemical added on to the surface of the fabric during
applica on process.
