The term finishing includes all the mechanical and chemical processes employed commercially to enhance the acceptability of the merchandise, except those procedures directly concerned with coloring. The objective of the varied finishing processes is to form fabric from the loom or knitting frame more acceptable to the buyer. The newly formed cloth is generally dirty, harsh, and unattractive, requiring considerable skill for conversion into a desirable product. Before treatment, the unfinished fabrics are mentioned as gray goods, or sometimes, within the case of silks, as greige goods. Nature of Sample:  100% cotton woven fabric.

Textile finishing is two types one is a chemical process and the other is a mechanical process. Anti-crease finishing often known by various fancy terminologies is an important process of textile processing.  Resin finishing is known as Wash & Wear Finish or Anti Crease Finish or Crease Resistant Finish or Durable Press Finish and Wrinkle Free Finish.  Resins are  cross-linking agents, which form a covalent bond on reaction with –OH groups  of cellulosic materials in an acidic medium at a pH of 3-4. The cotton cellulose chain contains –OH groups in both Amorphous and Crystalline regions. There are Hydrogen Bonds between the –OH groups of the molecular chains.  after the load is applied to the cotton fabric chain of the cellulosic in fiber bend and remains permanent.
