A method for trim preparation of car interior parts includes the steps of cutting out templates of natural jute or linen fabric primer and a second natural cotton fabric or fiber paper, and impregnation of the fabrics with a water-based adhesive resin in each of the fabrics and drying thereof. The method also includes the steps of fabric pressing, forming a structure by adding an adhesive layer and a decorative sheet, applying primer on the decorative layer and drying it, and applying at least one layer of varnish onto the primer layer and drying it.

The tape incudes a water vapor-permeable air and water barrier article and a pressure sensitive adhesive layer. The air and water barrier article includes a fibrous layer having first and second major surfaces and a polymeric layer on a first major surface of the fibrous layer that penetrates into the fibrous layer but leaves at least some fibers exposed on the second major surface. The pressure sensitive adhesive layer is on the polymeric layer of the air and water barrier article. The tape can retain greater than 50 percent by weight of mortar applied according to the Vertical Mortar Receptivity Evaluation. The article includes a substrate, the tape, and a composite layer comprising at least one of gypsum, lime, or cement. The composite layer is at least one of dried or cured on the second major surface of the fibrous layer. Methods of making the article are also described.

Provided is a method for manufacturing a laminated film that can be molded into a complicated shape. A method for manufacturing a laminated film comprising: a step of forming an uncured hard coat layer by applying an active energy-ray curable composition for forming a hard coat layer to one side of a first support substrate having a thickness of 50 μm or more and 600 μm or less, and then drying the composition; a step of forming an uncured optical interference layer by applying an active energy-ray curable composition for forming a optical interference layer on one surface of a second support substrate so that the thickness of the uncured optical interference layer is between 15 nm or more and 200 nm or less, and then drying the composition; and a lamination step of laminating a surface of the uncured hard coat layer opposite the first support substrate and a surface of the uncured optical interference layer opposite the second support substrate to obtain a laminated film, wherein a stretch ratio of the laminated film at 160° C. is 50% or more.

A method for preparing a bifunctional film, including: (a) drying a first polymer solution to form a film to form an anti-adhesion layer; and (b) drying a second polymer solution over the anti-adhesion layer to form a film to form an attachment layer. The first polymer solution includes a first hydrophobic solution and a first hydrophilic solution, and in the first polymer solution, the weight ratio of the solute of the first hydrophobic solution to the solute of the first hydrophilic solution is 1:0.01-1. Moreover, the second polymer solution consists of a second hydrophilic solution.

A method for producing a cladding part for vehicles with a cladding part body that forms a cladding in the mounted state. A sandwich panel is formed and extends two-dimensionally in a plane with at least one transparent thermoplastic upper layer, a prefabricated, postprocessing-free intermediate layer, and a thermoplastic base layer. The at least three-layered sandwich plate is subsequently three-dimensionally formed under the influence of heat into a sandwich element forming the cladding part body.

A method of making a floor covering including a tufted textile substrate and a reinforcement backing system. A layer of reinforcement fibers is positioned on the ends of yarn stitches. Applicators are operationally connected such that adhesive is forced into the reinforcement fiber layer towards a primary backing substrate, and adhesive is also substantially simultaneously directed to form a pool of adhesive between the applicators, and a portion of the pool of adhesive is also substantially simultaneously applied as a layer of adhesive on the reinforcement fiber layer.

A thermoplastic composite article comprising a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material is provided. In certain instances, the article further comprises a skin layer disposed on the core layer and an adhesive layer between the core layer and the skin layer. In some configurations, the adhesive layer comprises a thermoplastic polymer and an effective amount of a thermosetting material to provide a post-molding peel strength between the skin layer and the post lofted core layer of at least 0.5 N/cm (in either or both of the machine direction or cross direction) as tested by DIN 53357 A dated Oct. 1, 1982.
