    摘要： The abrasion resistance of fabric composed partly or wholly of recycled wool fibers (reprocessed or reused wool) is increased by impregnating the fabric with an aqueous solution of an acrylate monomer containing a polymerization initiator, an acid, and, preferably, a surfactant promoting contact of the fibers with the solution. The fabric, which has been impregnated at a temperature below the polymerization initiation temperature, is washed with water to remove the impregnating solution from the exterior scaly surface of the wool fibers while leaving the solution within the fiber cortex, and thereafter the fabric is cured by heating it at a temperature above the polymerization initiation temperature of the acrylate monomer. The process provides a means for increasing the durability of the fabric without appreciable modification of other desirable properties of the fabric.

    摘要： A method is provided for treating and modifying solid, high molecular weight Lewis base polymers, particularly shaped structures such as fibers, filaments or knitted fabrics, to form branched polymer with improved electrical conductivity, water absorbency and dye receptivity while retaining the essential structural shape. The method comprises heating the polymer in the presence of an aqueous treating solution containing an ethylenically unsaturated monomer which does not readily polymerize under the conditions of treatment and a catalyst which is a source of hydrogen ions or protons. The treatment is carried out at a temperature and for a sufficient time so as to effect essentially single molecule addition of the monomer pendent to the polymer chain with substantially no graft polymerization of the monomer to the polymer. A particularly preferred embodiment of the method is the treatment of nylon 6,6 knitted fabric with an aqueous solution of acrylamide and hydrochloric acid for about one hour at 95.degree. C. to 100.degree. C.

    摘要： A water repellant fabric and a process to produce that fabric is provided. The process comprises; providing a fabric substrate having sites reactive with polymeric functional groups; contacting the fabric substrate with a functional group containing polymer; removing unreacted functional group containing polymer; and recovering a water repellent fabric. The appearance, stiffness and texture of the treated fabric is similar to the untreated fabric and the hand of the treated fabric is excellent.
