PRETREATMENT

PRETREATMENT

Natural fibers and synthetic fibers contain primary impurities that are contained naturally and secondary impurities that are added during spinning, knitting, and weaving processes. Textile Pretreatment is a series of cleaning operations. All impurities which cause adverse effect during dyeing and printing is removed in the Pretreatment process.

Pretreatment processes include desizing, scouring, and bleaching which make subsequent dyeing and softening processes easy. Uneven desizing, scouring, and bleaching in the pretreatment processes might cause drastic deterioration in the qualities of processed products, such as uneven dyeing and a decrease in fastness.

Sequestrants & Chelating Agents

Sequestering agents are employed in a number of applications such as builders in detergent formation to eliminate interfering effects caused by dissolved metal salts, particularly calcium or magnesium salts. Sequestering agents are also employed in other applications requiring control of metal ion content in aqueous solution such as waste water treatment, potable water conditions, micro-nutrient solubilization, gas conditioning, photographic development processing catalysis of chemical processes, finishing and conditioning of textile, etc.

The present invention relates to a novel composition of matter having utility in the sequestering or complexing of metal ions particularly calcium and / or magnesium ions. More particularly, the present invention is unique combination of water – soluble aminopolyacetate demonstrating improved chelating properties

ADVANTAGES
Prevention of pinhole formation due to catalytic oxidation caused by iron during bleaching (chelates iron / heavy metals).
During dyeing, it prevents spots, shade change and unevenness by chelating heavy metals and dispersing impurities.
Improved rinsing due to the scale inhibition (effective at low concentration such as its presence in rinse bath).
During fabric preparation sequester also provides iron chelating to prevents fabric / yarn damage and provides additional stabilizing effect on the hydrogen peroxide.
