It can be obtained by entanglement with the mechanical external force of the flow . In addition, because it is entangled by the fluid flow , it is more uniform and excellent in strength.
ing. In addition, when forming a fiber web by the card method, if the orientation direction of the fibers includes the crossed fiber webs that intersect with the length direction of the fiber web, the strength in the width direction is improved, and there is no directionality. This is a more preferable orientation direction because it can be cleaned. This crossed fiber web can be obtained by crossing unidirectional fiber webs with a cross layer or the like.
