Low permeability and high strength woven fabric and methods of making the same
11634841 · 2023-04-25 · ·

A method for producing a woven fabric comprises weaving fibers in a warp direction and a weft direction to form a fabric having a top surface and a bottom surface, wherein the warp fibers and weft fibers each comprises one or more filaments of a synthetic polymer having substantially uniform cross-sectional composition. At least a portion of the filaments in the fibers on the top and/or bottom surface of the fabric are then fused together in the presence of a heat transfer liquid or vapor added during the fusing step or added in a prior step of the fabric production process and retained by the filaments. The fusing step produces a treated fabric having a tensile strength in both the warp and weft directions of 1000 N or greater and having, in the absence of any coating, a static air permeability (SAP) of 3 l/dm.sup.2/min or lower.

CUTTABLE KNITTED FABRIC AND METHOD FOR MANUFACTURING THE SAME
20230134953 · 2023-05-04 ·

A cuttable knit fabric of the present invention may comprise: a knitted fabric woven with a single yarn; a first reinforcing part disposed to correspond to a central portion on the lower surface of the knitted fabric; and a second reinforcing part disposed to surround the periphery of the first reinforcing part on the lower surface of the knitted fabric. A first reinforcing fiber of the first reinforcing part and a first reinforcing fiber of the second reinforcing part may be formed by tangling with the yam of the knitted fabric. The first reinforcing part and the second reinforcing part may be formed of different materials. The first reinforcing part and the second reinforcing part may have different tensile strengths.

Methods for producing through-fluid bonded nonwoven webs

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing first and second, different molten polymers to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymers, in a direction toward the porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying, in at least two different zones, a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.

CLOTH SUPPORT BASE

A cloth support base includes a cloth support surface and a storage portion. The cloth support surface extends in a first and a second direction. The storage portion includes a bottom wall and a plurality of side walls. The plurality of side walls protrude from the bottom wall in a third direction. The bottom wall and the plurality of side walls form a storage space configured to store a storage object including at least one of water vapor and water. The plurality of side walls and the bottom wall form at least one groove. The at least one groove is configured to guide the storage object stored in the storage space to move to the outside of the storage space in the first direction and is configured to restrict the storage object stored in the storage space from moving to the outside of the storage space in the second direction.

Process for producing polyvinyl alcohol articles

The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

Bulkiness recovery apparatus for nonwoven fabric
09777414 · 2017-10-03 · ·

A bulkiness recovery apparatus for nonwoven fabric includes a hot-air source; and a case unit including a base member, and first and second members. The first and second members face opposite first and second surfaces of the base member and partition first and second conveyor spaces. The base member has first and second hot-air chambers. The first and second surfaces have first and second jet inlets. The first and second hot-air chambers at least partly overlap in a direction normal to the first surface. First and second conveying directions of the nonwoven fabric in the first and second conveyor spaces are different. Hot air flows along the first conveying direction and is blasted from the first jet inlet into the first conveyor space. Hot air flows along the second conveying direction and is blasted from the second jet inlet into the second conveyor space.
