    IPC: C08L51/08 ,  D06M15/38

    Abstract: A method of modifying a synthetic or natural polyamide product, such as a fiber cloth, film or leather, wherein a graft polymerization is carried out on said product in an aqueous solution containing 5 to 60 mole % of carried acid and 95 to 40 mole % of methacrylic acid as monomer or by adding said aqueous solution to the polymerization system. The method provides an industrial-ly feasible and efficient means of graft polymerization of polyamide products by greatly improved grafting efficiency of acidic vinyl monomers to the product.

    Abstract: A fur-like napped fabric and process for manufacturing same are disclosed wherein a fiber layer comprising uncrimped short fibers or short fibers having a number of crimps of not greater than 10 crimps per inch are provided as a fiber layer on a base fabric. The fibers are then implanted into the base fabric by needle punching. Thereafter, the fibers are raised to form a nap. After needle punching, the base fabric and fibers may be bonded to each other by means of a backing treatment or the like which is carefully applied so as not to permeate the raised hair portion extending on the front surface of the fabric. Especially pleasing aesthetic effects are produced when the napped fibers have static frictional coefficients of less than 0.35 and wherein the bending recovery rate of said fibers is higher than 50%.
