Abstract

Textile material consisting wholly or partly of wool is rendered more resistant to felting and shrinking by impregnating it with a strong solution of methylol urea (i.e. the condensation product between an equivalent molecular ratio of urea and formaldehyde produced on standing of the reagents in neutral solution for several hours), squeezing, drying, and curing at 80 DEG -135 DEG C., and then impregnating with a solution of a strong mineral acid, squeezing, rinsing, drying, and curing at 90 DEG -135 DEG C. The amount of resin deposited may be 10-15 per cent by weight of the wool. The methylol urea solution is preferably of a concentration of at least 50 per cent by weight. The ratio of formaldehyde to urea may be slightly in excess of the equimolecular proportion to allow for evaporation of formaldehyde during the treatment. To improve the feel of the treated material it may be scoured, and it may be treated with a cation-active or other softening agent. The curing may be effected with the aid of infra-red radiation. The wear-resistance of the material is also improved by the antifelting treatment. In examples, wool yarns, woven and knitted fabrics, and hosiery, are subjected to the anti-felting treatment.
