Nonwoven fabrics are provided that include at least a first nonwoven layer. The first nonwoven layer includes multi-component fibers densely arranged and compacted against one another. The multi-component fibers comprise at least a first component comprising a first polymeric material including a first polyolefin and a second component comprising a second polymeric material including a second polyolefin, in which the first polymeric material is different than the second polymeric material. The first polymeric material, the second polymeric material, or both include a compatibilizer comprising a copolymer having a comonomer content including (i) at least 10% by weight of the compatibilizer of a first monomer corresponding to the first polyolefin and (ii) at least 10% by weight of the compatibilizer of a second monomer corresponding to the second polyolefin.

The present invention aims to provide a porous polyvinyl acetal object and a nonwoven polyvinyl acetal fabric each capable of exhibiting significantly high shock absorption. Provided is a porous polyvinyl acetal object having a large number of cells, including: a polyvinyl acetal; and a plasticizer, the porous object having an open cell ratio of 10% or higher, the porous object in the form of a sample with a size of 10 cm in length, 10 cm in width, and 4 mm in thickness having a coefficient of rebound (rebounding height/drop height) of 0.1 or lower in measurement of a rebounding height of a -inch SUS ball in conformity with JIS B 1501 dropped from a given drop height to the center of the sample placed on an iron plate with a size of 10 cm or more in length, 10 cm or more in width, and 1 cm in thickness.

A ball-shaped light heat generating fiber aggregate and a method for producing the same include a light heat generating material that is sprayed and applied to any one filament or a mixture of two or more filaments selected from the group consisting of a polyamide-based filament, a polyester-based filament, and a polypropylene-based filament, opening and mixing the same to separate the filaments, and producing a ball-shaped fiber aggregate.

The invention provides a connector assembly for fastening filter elements onto a supporting plate of a press filter, comprising a first cylindrical core, a first flange extending outward from the first cylindrical core, a second cylindrical core, and a second flange extending outward from the second cylindrical core. The first cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with a central through hole of the supporting plate, and the second cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with the first cylindrical core. Both the first cylindrical core and the first flange and both the second cylindrical core and the second flange are respectively molded integrally from a non-woven fabric which has the ability of self-sustaining and shape maintenance, and is moldable. The invention also relates to a press filter fitted with the connector assembly.
