摘要： A glass or pretreated meltblown fiber having a cationically charged coating thereon, the coating including a functionalized cationically charged, silicon containing carbohydrate polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the glass fiber. Also provided is a fibrous filter including a fibrous filter media having a cationically charged coating thereon, the coating including a functionalized cationic polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the fibers. Further provided is a method of preparing a fibrous filter. The method involves providing a fibrous filter which includes glass fibers or pretreated nonwoven fibers, passing a solution of a functionalized cationic starch polymer crosslinkable by heat through a fibrous filter under conditions sufficient to substantially coat the fibers with the functionalized cationic polymer, and treating the resulting coated fibrous filter with heat at a temperature and for a time sufficient to crosslink the functionalized cationic polymer present on the glass fibers.

摘要： There is provided a new aqueous temperature responsive delivery system made with a temperature responsive polymer and a bioadhesive which is intrinsically cationic. This system may also have an effective amount of a treating agent, which may be a medical or cosmetic agent. The bioadhesive, temperature responsive delivery system is useful in delivering moisturizers or pharmaceutically active agents to the user in controlled release manners, through the tissues in a body cavity.
