Yarn & Fabric Mercerzing - No More Now.?
Mercerizing for King Cotton,Yarn & Fabrics.
The process developed by John Mercer in the year 1844 was a treatment given to pure cotton to remove the spun yarn hairiness on the thread or fabric.On the yarn used for sewing it was very essential and on the fabric it gave a lustrous appearance and was smooth to the feel over the naked skin.This process used by most of the textile mills of high repute like Century,Finlay,Kohinoor,Khatau,Madura Coats etc,etc was on machines similar to the above shown pictures and went on till man-made fibers like viscose and polyester entered and made better apparel fabrics similar to that of mercerized cotton fabrics.
Even the Sewing Thread Industry's needs were met by the use of man made fibers.The machines were soon obsolete as blended man made and cotton fabrics met for more than the needs of consumer markets that required mercerized fabrics.
The process of mercerizing was to treat cotton,yarn or fabric in caustic soda solution of required degree of strength for a period of time engineered in the machine speed and there after washed throughly in several water tanks and until the material was 100% free of any caustic soda solution .Still thereafter the material was tested and confirmed to be free of any caustic soda solution.
These machines are still in use for cotton fabrics of very high value.
