Garment wash here refers to garment pre- wash performed afterproduction of garmentSs prior to using it by the consumers.; simple outline about di%erent garment wash has gi$en here<

17 N$RMA+ WASH)6ormal wash consists in washing garments in hot water with ade uatedetergent and softener, rinse in plain water and dry in tumble dryer until itis 1@@F dry. 0ome sodium is added to lend the garment a prominentwashed look. ater temperature, proportion of components of wash isad#usted as per re uirement of wash and types of fabric, the garment ismade of.

The softener makes the (ber soft and tumble-drying makes the fabricHu er. ;n e)pert technician can handle washing by an e)pedient way tosol$e many problems arising out during washing. ashing can also a%ectdi%erent garment parts di%erently. 0hell fabric may be solid color whilepocket may be white pocketing piece. ;fter washing it may appear thatpocketing piece has been stained.

This may happen because may be too much softener has been used orthe fabric bleeding color is of weak color uality. Though softener makesthe (ber soft but it also breaks the dye loose and may stain the fabric. Toomuch use of softener makes the fabric wa)y. 0o, one should cut a balancein using softener and other components in normal wash. n such casesgarment should be washed with less softener and check if the stainingproblem is got rid of or eliminated. f use of less softener cannot sol$e theproblem of staining indicates poor color

Pigment ash is similar to normal wash but a bit costlier. The garment issolid color pigment dye.

The re uirement is that the color should fade e$enly to lend the garmenta prominent washed look. Pigment wash re uires a higher temperature of

water than normal wash.819 Cse hot water E@-M@ degree 2D839 >oad the tumble washer not more than !@ F of its capacity. Thisenables garment to mo$e inside smoothly. f fully loaded with garmentsdue to friction of the garments with tumble body.

Pigment wash is required for the following reasons:

e)posed areas, such as the seams and pocket corners.0ometimes, bleach is added to the wash so that the color fades in a morepronounced manner. This is done to make na$y blue #eans into a morefaded light blue. 0uch wash re uires a lot of skill, e)perienceDworkmanship and e)pertise so that desired results are achie$ed. n stonewash the following points should be carefully checked<

27 !A?STI! WASH)2austic wash is basically a pre- printing wash. 2austic is a strong chemicalwith highly corrosi$e features. Prior to printing on cotton fabrics, greygoods are treated in boiling water with caustic, which has also strongcleaning power especially for grease. This wash can remo$e all soil, dirt,grease, (ne particles of cotton seeds as well as all foreign materials. ;s a

result only pure cotton (ber in the fabric for printing is left. This leads tostability of printing and well cleaned fabric. owe$er, when we want to docaustic wash on garments, we #ust do the opposite of the abo$eD prior toprinting fabric is not treated with caustic wash for cleaning.

Printing is done on the row & unclean fabric so that about?@F of the printing done on the surface maye$entually fade away. *inally, printedgarments are caustic washed. This leads to,about ?@F of the printing washed awayalong with the foreign materials- lea$ingabout !@F of the printing on the fabric.

This e$entually makes the design or stripeof desired look. *or this type of wash, theprinting must be pigment print withbinder. 'aking treatment should also beperformed so that

The color will stay on the fabric more orless securely to coincide with the causticwash to be done later.

37 GARMENT WASH AN# $@ER;#>E) This type of wash is also used for denim garments to gi$e them a speciallook. This is performed in the following way<

8".19 ash the denim garments with stone so that the double needleseams, pocket Haps and e)posed parts get washed down to light blue

color or white.8".39 Put into dye the tumble to dye the garments to get the desired color.

8".?9 ; coat of new color will appear on to the garment, especially, inareas where the garment has been washed to a light shade. This creates aspecial but di%erent look. n this process of wash, the lining or pocketingwill pick up the color too. 'y this wash, direct dye or reacti$e dye same asdyeing fabrics or yarn may be used. 4irect dye is cheaper. 0o, direct dyemay be used with concomitant use of color ()ing agent, after dyeing to

make the color more stable. n case of solid color fabric staining within thegarment is not a problem. owe$er, if garments of di%erent colors arewashed together by the consumers, color may transfer to other garments,so reacti$e dye is more preferable.

57 WHITENING)hitening agents are used to create a super white look. 8Cnless the

garments you wash is all colored namely no white color at all in the fabric,you should use whitening powder in the rinsing process to make the whitepart more white9 n denim where there are colored warp threads and whiteweft threads. f such garments undergo [stone wash and bleach[whitening powder is used in the (nal rinsing. This makes the white threadsin the fabric whiter and generates a stronger contrast between blue andwhite on the surface of the fabric.

;fter washing denim check the re$erse side of the fabric to e$aluate if ade uate whitening agent has been used during rinsing. t is a commonpractice that garments ha$ing white parts should be washed with
