Abstract: A non-woven fabric in which large fiber bundles of the fabric intersect one another, small fiber bundles thereof intersect one another among said large fiber bundles, and the fibers of the fiber bundles are being entangled with one another among the large fiber bundles, among the small fiber bundles and at the intersecting points of the fiber bundles, may be manufactured by fluid-entangling fiber webs on a support member having large pores to obtain said large fiber bundles therein; and further fluid-entangling fiber webs of the resultant intermediate on a support member having small pores from either the same direction or the opposite direction to form said small fiber bundles therein. The non-woven fabric has excellent draping property, covering property and abrasion resistance and can be used as an interlining, as a base material for synthetic leathers, as a variety of base materials, as an interior material, as a simple garment, as a medical gown, etc.

Abstract: A method for preparing water soluble fabric for chemical laces. The water soluble fabric is composed of webs of hot water soluble polyvinyl alcohol fibers and a water soluble resin fixably adhered to the fibers of which the fabric is composed.
