55be9034d4 Anti-static finishes may also be of polyamide type, being curable at moderate temperatures. Presetting of goods makes it possible to use higher temperature for setting without considering the sublimation properties of dyes and also has a favorable effect on dyeing behavior and the running properties of the fabric.

Color is a sensation caused when white light from a source such as the sun is reflected off a pigment on the surface. Calendering is the third important mechanical process, in which the fabric is passed between heated rollers to generate smooth, polished or embossed effects depending on roller surface properties and relative speeds. Weighting silk with metallic salts or polymer adds weight and improves handle.
Anti-pilling finish alleviates pilling, an unpleasant phenomenon associated with spun yarn fabrics, especially when they contain synthetics. Cotton is mercerized under tension, and all alkali must be washed out before the tension is released or shrinkage will take place. If the appropriate reagents are used, scouring will also remove size from the fabric although desizing often precedes scouring and is considered to be a separate process known as fabric preparation. At this stage even the most naturally white cotton fibres are yellowish, and bleaching, the next process, is required.[6] . Synthetic warp and weft threads in loosely woven fabrics are particularly prone to slip because of their surface smoothness when the structure of fabric is disturbed and appearance is no longer attractive. However, for white bed sheetings and medical applications, the highest levels of whiteness and absorbency are essential.[7] . With an aim to protect the skin of the wearer and the textile substrate itself, an anti-microbial finish is applied to textile materials.
