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.
CURABLE PREPREGS WITH SURFACE OPENINGS
Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.
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.
Pouch or Semi-Dense or Liquid Product with Applicator
A pouch (1) for semi-dense or liquid products and method for manufacturing are disclosed. The pouch (1) comprising a first half (5) and a second half (6) of a flexible sheet material, the flexible sheet material comprises at least an outer layer (10), a tie layer (15) and porous layer (20), the porous layer carrying at least partly a semi-dense or liquid product (25), whereby the first half (5) and the second half (6) form walls of the pouch, their respective porous layers (20) facing a product space formed by the first half (5) and the second half (6) and whereby a sealed seam (30) joins the first half (5) and the second half (6) of the flexible sheet material and peelably seals the pouch, the sealed seam (30) being formed by the tie layer (15) fully impregnating the porous layer (20) in the area of the sealed seam (30) forming a peelable seal.
Composite articles including textured films and recreational vehicle articles including them
A thermoplastic composite article comprising a porous core layer and a textured film disposed on a first surface of the porous core layer is described. The composite article can be configured as a recreational vehicle building substrate such as a ceiling or interior wall panel.
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-LAYER FILM
A multi-layer film includes a first-seal layer and a second-seal layer. The multi-layer film may be used to form a package for consumer-care products.
Semi-rigid display board
A display board has a foam core with elastomeric properties with a first display layer affixed on one side and optionally a second display layer affixed on a second side. The elastic foam core can have a closed cell structure and be made from a thermoplastic. The display layers can be heat welded directly to the respective sides of the core with or without additional use of adhesive or the layers can be attached via adhesive only and not heat. The foam core has a Shore 00 hardness of 20-100.
Multi-threat protection composite
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.
