Mercerising fabric stretching unit - has rollers with alternating ribs and grooves to give intermittent spreading action

摘要

In the mercerising of knit goods or wovens, the fabric is stretched while being treted with a caustic soda soln. A number of cylindrical rollers (12) are used with alternating ribs (13) and grooves (14) on their outer surfaces. The rollers engage in a zig-zag with each other for the fabric (a) to pass between them in a winding form.
