Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
60 words
A process for simultaneously printing and grafting a water-insoluble, thioated fabric which comprises: A. applying to said fabric a printing paste comprising: 1. at least one ethylenically unsaturated monomer, 2. a peroxidic free-radical initiator, and 3. a pigment or a dyestuff; and B. subjecting the pasted fabric to microwave energy having a frequency of about 900 Mega Hertz or greater.
