The Italian Lafer Liquid Ammonia Mercerizing Machine uses a low temperature mercerizing technique to minimize the damage to the cotton or spandex yarns. 

           The under processed fabrics are free to contract in order to achieve the least shrinkage possible while still maintaining the highly stretchy character of the denim. 

           One of the many other great advantages to this system is that it fully recycles the Ammonia gas used in the process.  In doing so it does not cause any impact on the environment.
