Abstract
Method and apparatus for modifying fabric and fiber by impaction with particles that create axially aligned micro-cracks and increased porosity allowing penetration of dyestuffs into the fiber or fabric without the need for swelling agents or carriers. The apparatus includes a container, pressurized gas supplied to a first inlet, particles supplied to a second inlet, and an outlet passage through which the particles and gas are supplied to a textile fabric.
Claims26
An apparatus for improving the dyeability of textile fibers which comprises:
- (a) a hollow cylinder having an interior surface with a curved wall having an opening in said curved wall;
- (b) means for inserting particles into said cylinder;
