影響を及ぼした。2. Description of the Related Art Nonwoven fabrics are classified into two types: non-elastic nonwoven fabrics and elastic nonwoven fabrics. A method of manufacturing an elastic nonwoven fabric includes a method in which a stretched elastic yarn is sandwiched in a fiber during a nonwoven fabric weaving process, or a rubber film or a rubber net produced by heating and melting is sandwiched in a two-layer nonwoven fabric. Thus, the stretchable nonwoven fabric is provided with elasticity that can expand and contract. However, the nonwoven fabrics manufactured by the above two methods formed wrinkles on the cloth surface due to the recovery shrinkage action of the elastic yarn or rubber film (net), which had a great effect on the value of the product.
