The customers who pay the highest prices is very crucial in the process of finishing and are very demanding with regard to shrinkage differences between and within fabric rolls. After weaving, the denim fabric should be mechanically and chemically treated to give it a soft and pleasant handle and correct dimensional stability. Finishing method of denim is crucial to profits in this customers World Health Organization pay the costs area unit very exacting with respect to shrinkage variations between and at intervals cloth rolls. Mittal traders are the leading in fabrics as well as they are the denim fabric manufactures in India as their workers and experts have workforce experience and perfect administration.
Singeing is a process that uses a gas flame to burn off the fluff on the surface of denim fabric. This method burns away surface material that produces the material look fuzzy. This process enhances the color, and the fabric wet ability is also increased.
It requires very high compression at preshrinking . Fabric that does not undergo the sanforizing process and is considered raw is likely to shrink up to 10–15% on the initial wash and continue to shrink up until the third wash, and sanforizing aims to reduce the shrinkage to 1–2%.
Calendaring is a process in which denim fabric is passed between rollers , under controlled heat and pressure, to produce a variety of surface textures or effects in fabric such as compactness, smoothness, glazing, etc.
Mercerization takes place in industries involving sodium hydroxide so as to increase the luster and dyeability and it is carried out after the denim is woven. It may be used for ring dyeing, keeping the dye on the surface of the yarns and to prevent dyes from fully penetrating the fibers.
Due to the removal of impurities such as wax, paraffin and oil after pretreatment processes, denim fabric loses its natural hand feel and therefore it is necessary to regain its softness. Softeners improve abrasion resistance, increase tearing strength and diminish the risk of stitching thread and needle breakage during garment sewing.
In this method, the finishing agents are added to the foam, where the moisture content is minimum. The foam is laid on a rubber conveyor, evenly across the width of the conveyor by an oscillating feed pipe system, and a blade ensures a uniform layer of foam across the width. 80% water can be saved in foam finishing.
Denim fabric can be over dyed as part of a finishing process. Over dyeing can take place between resizing and the addition of softeners. The best results, however, are achieved after stone washing and subsequent bleaching. The preparation requirements for over dyeing.
