A method for producing a shaped article includes a deposition step, in which a mixture containing fibers and starch is deposited in the air; a moistening step, in which the mixture is supplied with water; and a shaping step, in which heat and pressure are applied to the mixture supplied with water to give a shaped article. The starch has a viscosity of 20 mPa.Math.s or more and 200 mPa.Math.s or less as a final viscosity at 50° C. of a 25% by mass aqueous suspension of the starch measured using a Rapid Visco Analyzer.

A high frequency attenuating device for an air flow induction system of a vehicle employing a thermoformed fibrous mat of any shape that fits robustly inside the duct. The dissipative nature of the fibrous mat helps in achieving broadband attenuation in the high frequency regime. The ability to manufacture the fibrous mat into any shape helps with restriction, targets different attenuation bands, and makes it more feasible to manufacture. Hybrid solutions are possible when combined with low frequency perforated silencers or high frequency QWT arrays injection molded onto them.

Nanofiber filter media ribbons are flexible elongate strips of polymeric material having a surface on which is formed an array of nanofibers. Ribbons are formable into woven or non-woven mats. The array of nanofibers can be configured to filter a predetermined contaminant from a fluid stream passing through the mats. Filter ribbons are formable by applying a moldable polymer to a first angular location of a rotating cylindrical roll having an array of nanoholes formed in a circumferential surface thereof so that the polymer covers the surface of the roll and infiltrates the nanoholes; cooling the polymer while rotating the polymer-covered roll to a second angular position; and removing the cooled polymer from the roll as an elongate film having an array of nanofibers formed on a surface thereof by the polymer that infiltrated the nanoholes.

A stapled melt spinning method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse bio-polyamide 6,10 into melt, extrude and spin it out spin heads of extruder into filaments, cool, draw and collect filaments into tow, then extend, cut and card the filaments into the staples, and spread the staples on a conveyer to form fibrous web. Next, blend and dissolve pulp by N-methylmorpholine N-oxide (NMMO) dissolving solvent, dehydrate it to form dope, and extrude and spin it out spin heads of extruder into filaments, then cool, draw and collect filaments into tow, and extend, cut and card filaments into staples, then overlay the staples over existing fibrous web to form a composite fibrous web of bio-polyamide 6,10 and cellulose filaments. Finally, coagulate, regenerate and convert fibrous composite of bio-polyamide 6,10 and natural cellulose into nonwoven fabric with hygroscopic metastatic feature by hydro-entangled needle punching, drying, winding-up processes.

The present disclosure relates to a non-woven fabric that is formed from a base part that spreads out in a planar shape and from a plurality of projecting parts that protrude in a thickness direction (Th) from the base part. Each of the projecting parts has a projecting surface part. Each of the projecting surface parts is configured such that the fiber density of the projecting surface part increases toward one side in a prescribed direction that is a surface direction of the non-woven fabric.
