AM Cotton: When cotton is treated with 2-amino ethyl sulphuric acid in NaOH, AM cotton is produced without changing its structure. Dyed AM cotton has better resistance to light and washing. Carboxymethylated (CM) cotton): Cotton treated with manochloro acetic acid and then NaOH is converted into CM cotton. There are two types of CM cotton and can accept crease resisting treatments with greater effect. The second form of CM cotton can be produced easily in mercerizing equipment at very low cost. The product can be crease proofed with particularly good effect. Cayanoethylated (CN) Cotton: Treatment of cotton with acrylonitrile yields chemically modified cotton described as cayanoethylated (CN) cotton. Though this looks and feel like ordinary cotton and many of its properties are similar to that type of cotton, but CN cotton has extremely good resistance to rotting influences. it has better resistance to the effect of heat than...
