Concentrated Silicone Emulsions
	Pretreatment Chemicals are used to convert raw fiber, yarn, or fabric into substracts suitable for dyeing printing and finishing. These fibers, yarns, fabrics could be of cotton, wool, silk, synthetics and blends of those. The pre treatment processes include :Concentrated Silicone Emulsions
	
	Desizing
	Scouring, wetting (removal of oils, waxes, dirt, etc thus imparting absorbency)
	Bleaching (removal of natural coloring matter)
	Mercerizing (increasing dye-ability, lustre and strength)
	Pretreatment requirements are as follow:
	Uniformity and levelness of effects
	High absorbency
	Low ash content
	Freedom from size
	High degree of whiteness
	Absolute absence of husks
	High dye absorbing power
	Thus pretreatment occupies a critical position in wet processing. More than 60% of the problems encountered in finished fabrics are directly attributed to lack of proper preparation.
