  • Textiles having a wash-durable silver-ion based antimicrobial topical treatment
    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.

  • Flame and shrinkage resistant fabric blends and method for making same
    Patent number: 6818024
    Abstract: Fabric blends of inherently flame resistant fibers and flame resistant cellulosic fibers that contain a flame retardant. According to the method of production of these blends, the inherently flame resistant fibers can be dyed a full shade of color without depleting the flame retardant contained in the cellulosic fibers. In addition, the potential for laundering shrinkage of the inherently flame resistant fibers of the blends is reduced regardless of whether both, one of, or neither of the inherently flame resistant fibers and the flame resistant cellulosic fibers are dyed. Dyeing and/or shrinkage prevention of these blends is conducted at temperatures below 100° C., typically approximately between 70° C. and 100° C.

  • Method of after-treatment of a dyeable nylon textile surface with a stain resist and the article produced thereby
    Patent number: 6811574
    Abstract: A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed. After coloring, a stainblocker composition having a temperature from twenty to ninety-five degrees Celsius (20 to 95° C.) is applied. If the articles are carpet tiles, the stainblocker is applied using a flood process.
