IPC: D03D1/00
Filed: 1994-08-26
Granted: 1997-02-10
Abstract: PCT No. PCT/CA93/00075 Sec. 371 Date Oct. 24, 1994 Sec. 102(e) Date Oct. 24, 1994 PCT Filed Feb. 25, 1993 PCT Pub. No. WO93/17180 PCT Pub. Date Sep. 2, 1993A paper machine dryer fabric includes hollow thermoplastic monofilaments to replace at least a portion of the wefts, also known as cross-machine direction strands. Fabrics including such monofilaments may be either a woven fabric, or a spiral fabric. The deformable nature of the hollow monofilaments decreaes the air permeability of the fabric, and in the case of spiral fabrics, improves monofilaments retention within the helical coils between the hinge yarns. The hollow monofilaments have a solidity in the range of from about 60% to about 75%. A suitable thermoplastic is polyethylene terephthalate. Hollow monofilaments do not have the disadvantages of other deformable yarns, such as spun yarns, multifilament yarns or plied monofilament yarns, each of which tend to hold and entrap within their structure both water and foreign matter.

IPC: C02F3/10
Filed: 1989-03-03
Abstract: A filler and a process for producing it, where the filler, in the case of the biological treatment of sewage, should in particular exhibit a "biological meadow" which is necessary for this purpose, and a uniform moistening ability. In the case of known fillers which consist of strips, it has been found that the strips straighten under influence of encrustation and thereby form a pore foothold for the "biological meadow" and seek to become attached to each other. The purpose of the novel filler is to eliminate this drawback, and for it to be easy to manufacture and install. The novel filler exhibits at least one tensile member (fibre 29), which has been located beside the strips 20. When suspended, this takes up the load such that the strips 20 are essentially unloaded and thereby retain the shape they were given during manufacture. The filler is especially suitable for the biological treatment of sewage and drinking water, i.e. denitrification. <IMAGE>
