  • Patent number: 7429558
    Abstract: The invention relates to a fabric treatment composition which comprises a self-crosslinking polymer possessing pendant azetidinium groups. A first aspect of the invention comprises an azetidinium functionalized polymer containing primary or secondary amine groups. Cross-linking reactions between the azetidinium group and primary or secondary amine groups do not form quaternary groups and consequently do not result in a charged, cross-linked polymer. This lack of charge is believed to overcome the problems of stain fixing and dye adsorption. A second aspect of the present invention subsists in an azetidinium functionalized polymer of which the monomers comprise: an amino-acrylate and/or amino-alkacrylate monomer, and, optionally, further non-amino acrylate and/or alkacrylate monomer.

  • Patent number: 7166235
    Abstract: Disclosed are compositions and methods for treating and modifying surfaces and for enhancing delivery of active agents to surfaces treated therewith, wherein the compositions comprise siloxane polymers functionalized with pendant moieties comprising two or more anionic groups, at least one anionic group being a carboxy group. When applied to a suitable surface, the present composition forms a substantially hydrophobic coating of the anionic functionalized siloxane polymer on the treated surface. These polymers effectively deposit on surfaces that have cationic sites, which are capable of forming bonds or linkages with the anionic groups of the polymer. The treated surface becomes hydrophobic due to the deposition of the anionic functionalized siloxane polymer, which then imparts a variety of end use benefits to that surface such as ease of cleaning, soil release, stain removal and prevention, conditioning, etc.

  • Patent number: 6461386
    Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.
