  • Patent number: 6821936
    Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.

  • Patent number: 6802871
    Abstract: Compositions which, as well as water, contain certain sulfonate salts or polyhydric alcohols together with ethoxylated/propoxylated alcohols and ethoxylated alcohols are useful for pretreating textile sheet materials. Further ingredients also render them useful for hydrogen peroxide bleaching. The compositions, which provide the textiles with good primary wettability and good rewettability, are low-foaming. Batchwise pretreatment processes, for example in jet machines, therefore represent no problem.

  • Patent number: 6780201
    Abstract: Curly cellulose fibers having a high wet resiliency and a method of making high wet resiliency curly cellulose fibers with a chemically-assisted curling method. Polymeric reactive compounds are used to provide intrafiber crosslinking in curly fibers, thereby chemically setting the curl in the fibers, resulting in fibers that are stiff enough to not collapse upon wetting. These high wet resiliency curly cellulose fibers maintain a capillary structure during fluid acquisition and distribution, thus increasing absorbency.
