ABSTRACT:
The invention relates to a method of making a solid-liquid filtration cloth, a solid-liquid filtration cloth, and a filter in which the solid-liquid filtration cloth is arranged. The filter cloth (7) is provided with yarns (13b) having a highly changing length and a long free run in the weave. When the length of the yarns (13b) is allowed to shorten significantly, a filtration portion (15) on the side of a surface (14) of the cloth obtains a corrugated shape, providing the cloth with a large filtering area.
