Abstract
Provided herein is a process, compositions and machinery for performing digitally chemical cutting of a fabric, using digital inkjet methodologies and machines, being particularly, but not exclusively, suitable for roll-to-roll printing configuration, and based on digital printing of a fabric-cutting composition and a fabric-penetrating composition directly on the fabric to obtain a cut or perforated fabric.
Claims30
A process for chemically cutting a fabric, the process comprising:
- loading the fabric comprising degradable fibers on a digital printing machine equipped with at least two digital liquid jetting devices;
- digitally printing a fabric-cutting composition following a predetermined digital pattern, said composition comprises at least one activatable fiber-degrading agent suitable for degrading said degradable fibers;
- digitally printing a fabric-penetrating composition essentially on the same location of said predetermined digital pattern;
- and
- activating said activatable fiber-degrading agent in the fabric subsequent to said digitally printing, thereby obtaining a perforated fabric,
- wherein said perforated fabric characterized by a level of perforation that corresponds to a tearing force of said perforated fabric, said tearing force is higher than a tension force applied on said perforated fabric by any part of said printing machine.
