Fabrics made from synthetic fibres have excellent crease resistance that can be obtained without application of finishes. To impart crease resistance to cotton textiles, cotton fibers and blends with synthetic fibers, however, effective crease resistant finishes have been developed for all cotton textiles fabric e.g. bed sheets, shirts, trousers etc.
A variety of finishing techniques and crosslinking agents and resins have been used to impart dry and/or wet crease recovery to cellulosic fabric. For imparting dry crease recovery, the reaction is acid catalyzed and involves the application of formaldehyde or cyclic urea melamine (containing N-CH2OH or NCH2OR groups) to the fabric by pad-dry-cure-wash process. This produces smooth drying fabrics with crease recovery angles of 2300-2500. The catalysts normally used include magnesium chloride as well as organic acids. Finishing RecipesBOTTOM WEIGHT FABRICS :
