  • Methods and compositions to enhance stain resistance of nylon carpet fibers: thlocyanate to reduce yellowing
    Patent number: 5230708
    Abstract: This invention relates to improved methods and compositions to enhance stain resistance of carpet fiber. The improved methods relate to a continuous aftertreatment for dyed carpet fabric and to two-step processes, either batch-batch, batch-continuous or continuous-continuous. The improved compositions are used in the processes to enhance stain resistance of carpet or carpet fiber and to overcome various prior drawbacks, such as, yellowing, oxidation and durability to cleaning. The sulfonated aromatic condensates are used to enhance stain resistance, and can be combined with fluorocarbon compounds for soil resistance, thiocyanates, and/or salts having divalent cations, such as magnesium sulfate. Also various dispersing agents, buffering acids and sequestering agents are disclosed.
    Type: Grant
    Filed: June 1, 1989
    Date of Patent: July 27, 1993
    Assignee: Allied-Signal Inc.
    Inventors: Dale A. Hangey, Paul W. Harris, Daniel J. Corcoran, Jr., Michael P. Friedberger, Charles J. Cole, William A. Archie, Roger N. Spitz
