Zusammenfassung: | The present invention provides a method of making a nonwoven fabric of continuous fibers that includes forming a nonwoven web on a highly porous woven or knitted forming fabric that defines a pattern of recesses that are bordered by spaced apart filaments extending between the outer surfaces of the fabric and that allows air to pass both downwardly and sidewardly through the forming fabric. Bonded nonwoven webs are formed having protrusions with very low density and high surface area.
La presente invención proporciona un método para fabricar una tela no tejida de fibras continuas que incluye formar una trama no tejida en una tela tejida altamente porosa o tejido de formación que define un patrón de rebajes que están rodeados de filamentos separados que se extienden entre las superficies exteriores del tejido y que permite que el aire pase tanto hacia abajo como hacia los lados a través del tejido de formación. Se forman las tramas no tejidas unidas que tienen protrusiones con muy baja densidad y alta área superficial. |
