20220195661 · 2022-06-23 ·

[Problem] To provide a novel method for manufacturing synthetic leather that is colored using dye.

[Solution] A method for manufacturing synthetic leather having an outer surface layer on a base fabric, said method comprising the steps of: (i) coating a releasable base material with an outer surface layer composition containing a polyurethane resin and at least one dye selected from natural dyes and chemical dyes, and drying the coating to form an outer surface layer; and (ii) layering the outer surface layer over a base fabric.

CALCIUM ALUMINATE CEMENT AND CALCIUM SULFOALUMINATE CEMENT CATALYSTS IN GYPSUM PANELS AND USE THEREOF
20220194856 · 2022-06-23 · ·

Water-resistant gypsum products may be produced using a novel catalyst that includes calcium aluminate cement and/or calcium sulfoaluminate cement. For example, a water-resistant gypsum panel may have a core comprising: interwoven matrices of calcium sulfate dihydrate crystals and a silicone resin, wherein the interwoven matrices have dispersed throughout them a siloxane polymerization catalyst comprising (a) 55 wt % to 100 wt % calcium aluminate cement and/or calcium aluminate cement and (b) 0 wt % to 45 wt % and magnesium oxide, wherein the weight ratio of the siloxane polymerization catalyst to the calcium sulfate dihydrate is 0.01-5:100. The water-resistant gypsum panel may have an absence of one or more of: Portland cement, limestone, aragonite, calcite, dolomite, and slaked lime.

Air and water barrier article including inelastic porous layer

The air and water barrier article includes a polymer-coated inelastic porous layer including a water-vapor permeable polymeric coating disposed on at least one major surface of the inelastic porous layer and an adhesive disposed on a major surface of the polymer-coated inelastic porous layer. The inelastic porous layer can include at least one of surface-modified fibers or natural cellulose fibers. The polymer-coated inelastic porous layer can at least one of a water strike through time of not more than 180 seconds or an absorbance capacity of at least one-half gram per 116 square centimeters. The adhesive may be exposed, in contact with a release surface, or adhered to a surface of a building component. A method of applying the air and water barrier article to a surface of a building component is also disclosed.

Melamine wipes and methods of manufacture
11365496 · 2022-06-21 · ·

Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.

Curative

A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with β-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.

Multilayer lining for clothing

The present disclosure relates to a breathable, reusable, leakproof, absorbent, antimicrobial, waterproof and vapor disperser multilayer lining for clothing. A purpose of this lining is to avoid the release of body fluids such as sweat, blood, vaginal fluids, menstrual fluid, urine, breast milk or postoperative fluids.

PRESSURE-SENSITIVE ADHESIVE SHEET

Provided is a PSA sheet comprising a fabric sheet and a PSA layer laminated on the fabric sheet. The PSA layer comprises a base polymer and a tackifier resin. The base polymer is a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound. The PSA layer has a thickness greater than 100 μm and less than 190 μm.

Thermal/acoustical liner

A multi-layer liner material for use as a thermal and acoustical insulator which is lightweight, breathable, hydrophobic, oleophobic and fire-resistant. A central insulation core layer is contacted on a first surface by a first highly breathable layer and on a second surface by a second highly breathable layer, such that these three layers are resistant to water or oil penetrating the insulation core layer causing the liner to gain weight. The first and second highly breathable layers are preferably made from inherently flame resistant fibers and treated with a fluorocarbon surface treatment for water repellency, UV resistance and mold/mildew resistance. The first highly breathable layer is adjacent a facing layer while the second highly breathable layer is adjacent a backing layer. At least one surface of one of the first or second highly breathable layers, or facing or backing layers may include a carbon printing pattern to provide ESD protection.

COMPOSITE STRUCTURE AND DOUBLE-SIDED ADHESIVE TAPE
20220169896 · 2022-06-02 · ·

Provided is a composite structure capable of bonding a fabric and a synthetic resin material with good workability without affecting the texture of the fabric and having sufficient load-withstanding performance at a very high temperature.

The composite structure comprising a synthetic resin material, a fabric, and a double-sided adhesive tape that is disposed between the synthetic resin material and the fabric and bonds them together, the composite structure having a shear strength at 140° C. 15 mN/mm.sup.2 or more.
