Various nylon filamentary materials, including twine, rope and other cordages, are rendered resistant to knot and other interlacement slippage by treatment with certain latex compositions that form a tightly-adhering, blockage-promoting and -assisting surface film on the treated filamentary product so as to enhance physical knot strength propensities and characteristics of the treated-twine and equivalent product insofar as particularly relates to mechanical undoing of the knot under pulling stresses (as distinct from "knot strength" break-point tests indicative of the tensile strength of the filamentary nylon product, per se). Styrene (i.e., "St")/butadiene (i.e., "Bu") and like and analogous synthetic resinous latices-especially those of the carboxylated variety-are particularly good for achievement of the anti-slippage in knot formation enhancement of the nylon filamentary goods involved. The treating method adapted to bring about the advantageous desiderations as well as the beneficially treated nylon filamentary product are also involved in comprehensive keeping with the invention.
