Title:
BAG-LIKE FILTER
Document Type and Number:
WIPO Patent Application WO/2019/163709
Kind Code:
A1
Abstract:
Provided is a bag-like filter that is not more costly but has better durability than conventional bag-like filters, and can thus be replaced less frequently. In addition, provided is a bag-like filter which is more capable of capturing fine solids than conventional bag-like filters, and can achieve both high filtering performance and durability. This bag-like filter, which is used to filter a solid-containing waste liquid, comprises a bag-like round knitting fabric obtained by using a fibrous material, at least partially formed of an elastic fiber, for all or a portion of the round knitting fabric. The bottom section of the bag-like shape has a portion in which a knitted fabric is at least double-knitted.
