A research project subjected wool flannel fabrics to a novel treatment aimed at improving insect resistance. Reduction of the cystine linkages by treatment with thioglycolic acid (TA) or tetrakis (hydroxymethyl) phosphonium chloride (THPC) formed thiol grous, which were subsequently crosslinked with bifunctional reactive dyes. The researchers tested the performance of four TA solutions (0.250 mole and 0.500 mole at pH 6 and 7). The tested crosslinking agents included C. I. Reactive Red 195 and C. I. Reactive Black 5. Evaluation of insect resistance according to an AATCC test method revealed that the treatments improved resistance to damage by clothing moth larvae. C. I. Reactive Red 195 dye, when used in conjunction with the THPC/dye reduction treatment, yielded the best results. Adverse effects on fabric strength, shrinkage, and stiffness, however, limited the usefulness of these treatments. 22 refs.
