Abstract

In order to improve the shrik resistance of wool, the wool fabric was treated with polyurethane derivative and polyurethane dispersion etc. and the following results are drawn; (1) The optimum condition for the shrink resistance of wool fabric was polyurethan concentration of about 80g/$\ell$, PH of 7, the curing temperature of about 140$^{\circ}C$, and the curing time of 1 minute. (2) The physical properties such as the tensile strength and elongation, crease recovery, handle, tearing strength, and pilling were not lowered by the above treatment. (3) The affinity for acid dye of treated wool fabrics did not relatively changed.
