  • Patent number: 6863697
    Abstract: In a preferred embodiment, the present process involves subjecting a fabric having splittable conjugate yarns both to an acidic treatment and to a basic treatment, each of which erodes a portion of the components of the conjugate yarns. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The basic treatment has a similar effect on the polyester element of the conjugate filament, making it more hydrophilic. The at least partial removal of the polyamide component, coupled with the increased hydrophilicity of the polyester component, results in a fabric having enhanced absorptive properties. In an alternate embodiment, treatments with only acid or only basic solution may be employed.

  • Patent number: 6860906
    Abstract: Described is a process for preparing concentrated solutions or suspensions of anionic organic compounds which comprises a) acidifying an aqueous solution or suspension of an anionic organic compound containing salts and/or impurities to a pH of 4.5 or less, if the pH is above this value, so that b) the anionic organic compound is water-insoluble and precipitates in the form of the free acid, c) bringing the suspension to a salt content below 2% by weight, based on the total weight of the retentate, by means of ultrafiltration with a membrane having pore diameters of from 0.001 to 0.02 ?m, and d) optionally washing out the salts with water having a pH below 4,5, e) optionally carrying out acid-free washing with water thereafter, and then f) concentrating, so that the amount of anionic organic compound is 5-50% by weight, and g) if desired, bringing the anionic organic compound into solution by adding an appropriate base.

  • Patent number: 6852134
    Abstract: A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed. A pile surface structure having pile elements containing nylon yarns having both acid dyeability and cationic dyeability is dyed with both acid dye and cationic dye and then passed through a hot stainblocker treatment bath and a cooling zone. Substantially the entire height of each pile element is coated with a stainblocker composition whereby the pile surface structure has a stain resistance of 9 or higher on the AATCC Red 40 Stain Scale. The resulting pile surface has good color separation and stability, and no color loss from the catatonically dyeable yarns.

  • Patent number: 6836915
    Abstract: In the process for continuously dyeing a poly(trimethylene terephthalate) bulked continuous filament yarn carpet an aqueous dyeing solution is applied to a continuously moving poly(trlmethylene terephthalate) bulked continuous filament yarn carpet at a temperature of 45° C. to 100° C., and then the poly(trimethylene terephthalate) bulked continuous filament yam carpet is steamed, rinsed and dried. Before applying the aqueous dyeing solution the carpet is heat-set at 120 to 150° C. The carpet is steamed with saturated steam at 102 to 150° C. for 5 to 10 mm. The aqueous dyeing solution does not include an anti-frosting agent. The process also advantageously includes heating the carpet with a dry heat of 140 to 300° C. for 30 to 60 sec after steaming the carpet and before rinsing it.
