Method of manufacturing fabric

Abstract

A method of manufacturing waterproof, highly absorbent, and highly flexible fabric comprises drying TPU material or thermoplastic elastomer at about 50° C. to 150° C. for about predetermined hours, adding a bridge agent in the dried TPU material or thermoplastic elastomer for mixing and heating at about 60° C. to 280° C. for about 30 seconds to 5 minutes for melting, pouring the melted material into an endless shallow mold to form a continuous film, contracting a fabric material at about 50° C. to 180° C. for about 1 second to 5 minutes, placing the fabric material onto top and bottom surfaces of the film and pressing same at about 50° C. to 250° C. to form a composite fabric, cooling and shaping the composite fabric at about 5° C. to 60° C., and drawing the shaped composite fabric around a roll to produce the finished composite fabric.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of Invention [0002] The present invention relates to fabric manufacturing and more particularly to a method of manufacturing composite fabric with improved characteristics including being waterproof, highly absorbent, and highly flexible. [0003] 2. Related Art [0004] Fabric has been widely used as diapers, clothes, or the like. Conventionally, fabric comprises a number of layers. In one example, a composite fabric comprises an absorbent layer (A layer), an adhesive layer (S layer), and a waterproof layer (M layer). Also, a composite fabric can have an enhanced absorption if pulp or a highly absorbent material is employed as material of an intermediate layer. Alternatively, a composite fabric can have an enhanced adhesiveness if carbon fiber is employed as material of an intermediate layer. Still alternatively, a composite fabric can have an enhanced rigidity if pulp and plastic powder are employed as material of an intermediate layer. [000...
