A terry cloth article having a frosted appearance includes a plurality of naps the tips of which are bleached. A method of treating a dyed terry cloth to produce a frosted appearance includes the steps of impregnating granules of an absorbent material with a solution including a bleaching agent, and contacting the terry cloth with the granules for a time sufficient to bleach at least a portion of the dye from the naps of the terry cloth. After residual bleaching agent remaining on the terry cloth is neutralized, the terry cloth is subsequently contacted with a solution including an effective amount of an anti-peeling agent for a time sufficient to substantially eliminate peeling. Optionally the terry cloth can subsequently be overdyed with a second dye of a different color than the color of the terry cloth.
Article en tissu-éponge à aspect givré comprenant plusieurs poils dont les extrémités sont blanchies. Le procédé de traitement d'un tissu-éponge coloré en vue de lui conférer un aspect givré consiste à imprégner des granulés en matière absorbante d'une solution renfermant un agent décolorant, et à mettre le tissu-éponge au contact des granulés pendant une période suffisamment longue pour éliminer au moins partiellement le colorant des poils du tissu-éponge. Après neutralisation de l'agent décolorant restant sur le tissu-éponge, on met ce dernier au contact d'une solution renfermant une quantité efficace d'un agent anti-pelage, et ce pendant une période suffisamment longue pour éliminer sensiblement tout pelage. Ensuite, on peut éventuellement surteindre le tissu-éponge à l'aide d'un second colorant ayant une couleur différente de celle du tissu-éponge.
