Method for producing a wet-laid nonwoven fabric

A method for producing a wet-laid nonwoven fabric for a semipermeable membrane supporting body, the method comprising: performing papermaking according to a wet papermaking method by using a fiber slurry containing a synthetic fiber as a main constituent fiber; drying the fiber slurry; subsequently subjecting the dried sheet to hot press processing two times by using a heat calender apparatus, wherein the hot press process temperature in the second treatments is adjusted to be higher by 10 C. or more than the hot press processing temperature in the first treatment, while treating the dried sheet by using a hard nip heat calender apparatus equipped with a combination of a metal roll and a metal roll for at least one time of the hot press processing; and thereby obtaining a wet-laid nonwoven fabric for a semipermeable membrane supporting body.

METHOD OF MAKING A SPUNBOND NONWOVEN LAMINATE

An apparatus for making a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers has a row extending in a travel direction of two, three, or four spinning beams each emitting a multiplicity of multicomponent crimped continuous filaments with the filaments of each beam having a degree of crimp different from that of the filaments of each of the other beams. Respective extruders supply each beam with the components of the respective filaments and respective supply units feed each of the extruders with the respective components. The rate at which the components are supplied to the extruders is adjusted for varying the proportions of the components in each filament. A conveyor extends in the direction below the beams and receives the filaments as respective layers from the respective beams.

Bonded Insulation Product Batt from Spent Carpet and Waste
20240142041 · 2024-05-02 ·

A thermal insulation batt is created from recycled carpet fibers and fire resistant cotton shoddy bonded by staples of bi-component fiber having a polyester core and low melting polymeric sheath. The low melting polymeric sheath melts at a temperature well below the melting or degradation temperature of any of the carpet fibers from the recycled carpets. Since the sheath has a small thickness, the amount of melt created is small and bonding occurs only between the bi-component staple fiber and adjacent carpet fiber or fire resistant cotton shoddy without melt overflow. The rigidized thermal insulation batt can be used in a building between studs and may be used in an automobile door for sound proofing. This product is particularly well suited for use as acoustic and thermal insulation in buildings as non-load bearing partitions in interior offices of commercial buildings. This bonded low density composite fibrous structure has fire retarding constituents incorporated within the batt to retard propagation of building fire. These stated uses are non-limiting; and other uses are contemplated, including automobile interior structures.
