Abstract: A polishing pad includes a non-woven cloth and a continuous porous polymer. The non-woven cloth includes fibers. The polymer includes a plurality of holes communicated with one another. The polymer is cured in and bonded to the non-woven cloth. A surface of the polishing pad is constituted by the fibers of the non-woven cloth and the polymer.

Abstract: The present invention relates to a method of producing a polishing pad, comprising steps of: (a) providing a base material comprising a plurality of fibers; said base material having a surface for polishing a substrate; (b) impregnating the surface of the base material with an elastomer solution; (c) curing the elastomer impregnated in the surface of the base material to form a plurality of first continuous pores embedded in the elastomer and fibers; (d) impregnating the surface of the base material and elastomer obtained in the step (c) with a condition polymer solution; and (e) curing the condition polymer impregnated in the surface of the base material and elastomer and partially filling the condition polymer into the first continuous pores to form a plurality of second continuous pores.

Abstract: A method is disclosed for making permeable artificial leather that is realistic and permeable regarding air and liquid. At first, a non-woven cloth provided. A semi-product of the artificial leather is provided by means of immersing the non-woven cloth in a solution of a polymer resin. A highly porous sheet is provided. Finally, the final product of the artificial leather is provided by means of adhering the highly porous sheet to the semi-product of the artificial leather so that gaps exist between the highly porous sheet and the semi-product of the artificial leather.

Abstract: A process is disclosed for making ultra micro fiber artificial leather. Firstly, a substrate is made from ultra micro fibers of sea-island type and a reinforcement layer via needle punch or water jet. The ultra micro fibers all include a sea component and island components. Then, the sea component of each of the ultra micro fibers is dissolved. Finally, the substrate is submerged in elastomeric resin.
