Soil-resistant yarns, aqueous finish for yarns, and process for producing a soil-resistant
yarn |
(57) Soil-resistant carpet yarns are provided by providing yarns coated with a soil retardant,
for example, a fluorochemical, and a retaining agent, for example, zirconium oxide.
Such yarns when used in the manufacture of carpets retain their soil-resistant properties
during the carpet dyeing and finishing operation; the zirconium oxide in some way
promotes the retention of the fluorochemical on the yarn.
