A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fiber web or a thermoplastic film, and at least two unidirectional oriented-fiber layers B and B′, the layers B and B′ having a bidirectional fiber orientation. The layers are not only needled but also stitched to one another.

ENHANCED CO-FORMED/MELTSPUN FIBROUS WEB STRUCTURE

An enhanced, co-formed fibrous web structure is disclosed. The web structure may have a co-formed core layer sandwiched between two scrim layers. The core layer may be formed of a blend of cellulose pulp fibers and melt spun filaments. The scrim layers may be formed of melt spun filaments, and the filaments forming one or both scrim layers may have a number average diameter of 4.5 μm or less. Filaments of one or both of the scrim layers, and optionally the core layer, may also be meltblown filaments. Alternatively, the filaments forming the scrim layers may constitute from 1 to 13 percent of the weight of the structure. Alternatively, the scrim layers may have a combined basis weight of from 0.1 gsm to less than 3.0 gsm. A method for forming the structure, including direct formation of layers, is also disclosed.

FIBER-REIMFORCED MOLDED BODIES MADE OF EXPANDED PARTICLE FOAM MATERIAL

The present invention relates to a molding made of expanded bead foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the expanded bead foam. The two ends of the respective fibers (F) that are not surrounded by the expanded bead foam thus each project from one side of the corresponding molding. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings of the invention from expanded bead foam or the panels of the invention and for the use thereof, for example as rotor blade in wind turbines.

Waistbands having absorbent, wicking, expandable bandrolls and garments with same

A waistband for a garment includes a bandroll having an absorption layer and a wicking layer. The wicking layer controls stretch properties of the absorption layer. The waistband comprises a second material and wherein a shrinkage of a material substrate of the bandroll substantially matches a shrinkage of the second material.

Highly-filled polyurethane composites with fiber reinforcement

Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

Medical protective clothing materials

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

Multi-threat protection composite
11707100 · 2023-07-25 · ·

A multi-threat protection composite containing at least 15 textile layers having an upper and lower surface and a non-blocking pressure sensitive adhesive (NonB-PSA) composition on at least the upper surface of each textile layer. The NonB-PSA coating contains a pressure sensitive adhesive and a plurality of first inorganic particles, wherein the ratio by weight of the first inorganic particles to the pressure sensitive adhesive is greater than about 1.2 and wherein the NonB-PSA coating is in an amount of at least about 10 g/m.sup.2 on each surface the NonB-PSA coating is located. The first inorganic particles have a median primary particle size of less than about 5 micrometers.

Composite materials with structural and fire retardant capabilities
