Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.

Stretchable sheets comprising a variety of layers and zones and methods to produce such products
09731319 · 2017-08-15 · ·

The invention provides methods for producing flexible, stretchable, and/or elastic sheets and products having two or more zone having different material features and performance. The products can be comprised of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material of different types over different zones of a workpiece former or conveyor belt.

Dispersible hydroentangled basesheet with triggerable binder

The present disclosure is generally directed to a dispersible moist wipe comprising hydroentangled fibers and a binder composition. The moist wipe demonstrates high initial wet strength while maintaining effective dispersion in an aqueous environment. The moist wipe has potential application as a flushable surface cleaning product and/or a flushable cleansing cloth.

Molded object having nonwoven fibrous structure

To prepare a shaped product comprising a thermal adhesive fiber under moisture and having a fiber aggregate nonwoven structure. In the shaped product, the thermal adhesive fibers under moisture are melted to bond to fibers constituting the fiber aggregate nonwoven structure and the bonded fiber ratio is not more than 85%. The shaped product has an apparent density of 0.05 to 0.7 g/cm.sup.3, a maximum bending stress of not less than 0.05 MPa in at least one direction, and a bending stress of not less than ⅕ of the maximum bending stress at 1.5 times as large as the bending deflection at the maximum bending stress. The moistenable-thermal adhesive fiber may be a sheath-core form conjugated fiber comprising a sheath part comprising an ethylene-vinyl alcohol-series copolymer and a core part comprising a polyester-series resin. Such a shaped product can be used for a building board or the like since the shaped product has a high bending stress although the product is light and has a low density.
