The finish is called waterproofing and it is a durable finish. Water repellant finish is different from the waterproof finish. It means water, if showered on the fabric briefly, cannot make the fabric wet.
The whole cycle of finishing consists of mechanical and chemical processes, which are used depending on the kinds and end uses of the fabric. Mechanical processes include drying, calendaring, schreinering, embossing, sueding, raisingetc and chemical processes include in the application of special substances on the fabric, impregnation with size, starch, dextrin and other polymeric substances.
