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.

Methods and compositions to enhance stain resistance of nylon carpet

A new class of sulfonated 2-(2'-hydroxyaryl)-2H-benzotriazole compounds and method for using them and other sulfonated hydroxyaryl benzotriazoles on nylon fibers to improve stain resistance and dye lightfastness has been discovered. A process is provided for improving stain resistance of nylon fibers by treatment with sulfonated aromatic-formaldehyde condensate and fluorinated dry soil resist agents.

Methods and compositions to enhance stain resistance of carpet fibers

A water-tight ear enclosure having a water-impervious membrane secured to a flexible, inelastic strip about a portion of an opening in the membrane and an elastic strip secured to opposite ends of the flexible, inelastic strip and to the remaining portions of the opening in the membrane. The strip is formed of a thin, polymeric material in a J shape which is adapted to be received in front of the tragus of the ear and below and behind the lobule of the ear. The elastic strip is adapted to extend around the back of the external ear and in one embodiment includes an extension extending below the ear to form a secondary seal. The flexible, inelastic strip includes an adhesive for attaching the strip to the skin of a person adjacent the ear. The membrane is a flexible plastic film. The seal is established by the combination of the adhesively secured plastic strip and the inward biasing force of the elastic strip bearing upon the back of the external ear.
