  • Patent number: 5932672
    Abstract: Permanently stain resistant nylon and cellulosic fibers, and a method to impart permanent stain resistance to polyamide or cellulosic fibers, by covalently binding a stain resistant composition to a linking compound that has been covalently attached to the fiber are disclosed. This invention represents a significant advance in the art of textile treatments in that the covalently linked stain resist treatment is not removed after a series of alkaline shampooins. This invention is particularly useful in the preparation of commercial grade carpets for heavy traffic areas that will not lose their stain resistance after frequent shampooing.

  • Patent number: 5905127
    Abstract: Mesogens are provided based on substituted unsaturated carboxylic acids such as acrylic and methacrylic acid. Substitution of a variety of hydrophobic tails onto the carboxylic acid or acid derivative via the vinyl carbon proximal to the carbonyl of the carboxylic acid results in mesogens that are capable of forming thermotropic and single-phase lyotropic mesophases over a broad range of compositions. The mesophases can be polymerized to lock in the ordered phases.
