Methods for applying a polyhydroxyalkaonate (PHA) film to a substrate. The substrate is coated with an aqueous PHA emulsion or dispersion to form a PHA coating. Photonic energy is then applied to the PHA coating on the substrate to remove solvent and melt the PHA to form a continuous film.

A laminate lay-up includes a coated decorative paper layer having a decorative paper layer with a textured coating layer applied thereto. The textured coating layer is comprised of a UV curable coating composition. The laminate lay-up also includes a decorative layer and a core layer.

The present invention relates to a press-heating gas grafting hydrophobization apparatus, and a hot water-resistant paper and an oil-absorbing paper manufactured using the press-heating gas grafting hydrophobization apparatus. In the press-heating gas grafting hydrophobization apparatus according to the present invention, since a non-air-permeable dryer belt is provided surrounding and pressing a drying roller to prevent dissipation from a base material of a fatty acid chloride vaporized by the drying roller, the press-heating gas grafting hydrophobization apparatus has an advantage of improving efficiency of a gas grafting reaction. Therefore, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, the reaction amount of fatty acid chloride per unit area can be remarkably improved.

Disclosed herein are curled fiber mats. Also disclosed herein are methods of making curled fiber mats, comprising forming a fibrous media from a fibrous material, treating the fibrous media with a crosslinking agent to form a treated fibrous media, and drying and/or curing the treated fibrous media to produce a curled fiber mat that has a permanent curl.

Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.

A process for acylation of a solid material (3, 9) bearing reactogenic hydroxyls includes at least one fatty acid chloride (1) is distributed at least on the surface of the solid material (3, 9) using a distributor device (2) having an application surface. At least one fatty acid chloride (1) is distributed at least on the surface of the solid material (3, 9) is heated at a temperature, referred to as acylation temperature, below the vaporization temperature of the at least one fatty acid chloride (1), so as to enable an acylation of the solid material (3, 9). A stream of a gaseous composition (6) is directed over the said solid material (3, 9) at the acylation temperature, so as to entrain at least one portion of gaseous hydrochloric acid (7) formed by the acylation reaction

The application surface of the distributor device (2) is a velvet provided with velvet filiform elements that are suitable for taking up the at least one fatty acid chloride (1) by contact with the at least one fatty acid chloride, and releasing at least one fatty acid chloride by bringing the filiform elements of the velvet into contact with the solid material (3, 9). The distribution step (12, 14) is carried out so as to distribute over the solid material (3, 9) an amount of the at least one fatty acid chloride (1) of between 20 mg/m.sup.2 and 1 g/m.sup.2 surface area of the solid material (3, 9).

This invention refers to a manufacturing process for a high-performance resin-saturated decorative foil, designed for surface lining, both outdoors and indoors. The decorative foil can be used as a decorative lining for HPL-High-Pressure Laminate-panels and CPL-Continuous-Pressure Laminate-panels, as well as to be adhered to any flat or curved 2D surface.
