Whether it is possible to treat the cotton with NMMO and get the same result of mercerisation.

I agree with this view but we must also say that we was at that time who start mercerization with sodium hydroxide; it was simple and convenient. When the trend need for a flat Denim, has become also urgent to move in some direction and we have equipped our plants with the resources available. I also was preferred to support the cold system for better flat surface of the fibersthough and with some good method also tried to push the reaction inside of fibers. Today, the needs have changed and if we find different means to achieve target, also welcomed the ammonia finish or anything else that might be useful. Bye

Hi Vincenzo:
I appreciate your comments. Denim finishing quality around the world is generally bad and much of this is because of the machinery designs (integrated ranges) that have come into use over the last 20 years. The methods for penetrating the fabric with moisture are not adequate for relaxation of all the fibers, so compression is unstable. I wrote a denim finishing handbook of 50 pages which was published by the Bozzetto company in Bergamo last year that explained difficulties in denim finishing. It is available on their web site http://www.Bozzetto-Group.com
I did not cover ammonia because very few companies are using it now. Also, did not cover stretch finishing because that would have made the handbook too long.

Regards,

Harry Mercer

Same we can get it with hot caustic soda but it is very difficult to remove (reversible reaction) and it gives a very serious backstaining. The important issue is the tension applied: with or without tension febrics get harder or softer, shinier or more opaque. The total fiber mercerization produces a complete elimination of wrinkles after washing for the elimination of obvious friction between fibers and fiber.
We all agree on the benefits of this process compared to the caustic hydroxyl. Hope to have ammonia plants in the near future also competitive and environmentally friendly service to our industry.
