PretreatmentProcesses: Wetting, Scouring, Mercerizing, Sequestering Here, the yarn is prepared, in order to be ready for taking up dyestuff that includes cleaning, removing dirt and oils – to purify.

Dyeing Processes: Dispersing, Sequestering, Wetting, Anti-foaming, Reducing, Rope opening, Re-beaming There is only a single type of indigo, and the difference between good and bad dyeing is dependant on the auxiliaries.

Garmenting Processes: 3-D effects, Whiskering, Crunching, Different Looks e.g.Vintage, Distressed, Dirty, WetGarmenting provides the final touch on a pair of jeans and converts it into various looks and effects for that exclusive style you desire.

Weaving Processes: Sizes, Sizing Additives Dyed yarns are treated with Size and Sizing additives for weaving.

Finishing/Coating Processes: Flat Finish, Coating, Color Fast Finish, Resin, SoftenerThis is the stage where an authentic/classic denim fabric is transformed into colourful creations by using various types of finishings or coatings, thus offering different styles and provides the wearer with a distinctive character.

Characteristics: • Extraction of water-hardening substances and pectins • Removal of fibre impurities • Prevent precipitation of alkaline earth carbonates and formation of deposits • Low foaming

preparation and pretreatment

7

Characteristics: • Excellent wetting effect in causticizing • Promotes intensive & rapid penetration with caustic soda • Optimum wetting effect in the range of 12-22° Bé caustic soda • Lowers the risk of streakiness on denim especially after garment washing

Kieralon® Mercerizer MC

Design - Dyeing

Dyed at pH 11.5 – dyes are concentrated at the ‘outer ring’ of the yarns which results in darker shades

Dyed with 1.5 g/l(Hydrosulfite E at pH 11.5)

Characteristics:

• Re-wetting effect

• Anti-foam in the indigo dyeing process

• Keeps the rollers clean

• Stable even with high salt concentration

• Lowers risk of streaks after stonewash

Primasol® NF

Characteristics:

• Facilitate re-vatting in the dye bath • Prevent agglomeration of indigo pigment • Improve the rub fastness of dark denim • Stable against acid, alkali, water hardness and electrolyte

Setamol® WS

Dyed at pH 11.5 – dyes are concentrated at the ‘outer ring’ of the yarns which results in darker shades

Dyed with 1.5 g/l(Hydrosulfite E at pH 11.5)

Design - Weaving

10

Characteristics:

• Very flexible size film

• High weaving efficiency and low rate of yarn breaks

• Improves the desizing properties of natural and modified starch significantly • Less dust in sizing and weaving

• Improves the adhesion of starch to cellulose • When properly used with starch, Size CO maintains an ideal moisture content
