A multilayer structure including (a) a fabric, (b) a polyurethane foam containing a plurality of cells defined therein, wherein the foam contains at least one surfactant, and (c) a skin layer, wherein the skin layer comprises a wetting agent and an acrylic polymer having a glass transition temperature of 20 degree Celsius or less, and the foam resides between the fabric and the skin layer; and the process of preparing the multilayer structure.

Provided are an artificial leather and a method of manufacturing the same. The artificial leather includes: a base fabric; a polyvinyl chloride film bonded to a surface of the base fabric; bonding layer formed on a surface of the film; a first foam layer formed on the bonding layer in a patterned shape; a first color layer formed on a surface of the foam layer and having the same pattern as the first foam layer; and a surface treatment layer formed on a surface of the first color layer with the same pattern as the first color layer or formed on a surface of the bonding layer without the first foam layer and the surface of the first color layer. to the artificial leather of the present invention may have a light weight and implement various three-dimensional patterns and colors as compared with a conventional PVC foam artificial leather.

A process of manufacturing an artificial leather in one embodiment includes adhering a substrate onto a release cloth; flocking the substrate to form fur thereon; applying a synthetic resin to the substrate and drying same to form a half-finished artificial leather; foaming the half-finished artificial leather to fill interstices of the fur with the synthetic resin; sanding the half-finished artificial leather to remove excessive synthetic resin from the half-finished artificial leather; coloring the half-finished artificial leather to form a velvet-like surface; and removing the release cloth from the half-finished artificial leather to produce a finished artificial leather.

Multi-layer composite materials comprising a textile sheet material, production and corresponding method of use thereof

Multilayered composite materials comprise as components: (D) a textile sheet material, (E) optionally at least one bonding layer, and (F) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer,
wherein textile sheet material (A) and polyurethane layer (C) are bonded to each other directly or via bonding layer (B).

A renewable antibacterial waterborne polyurethane synthetic leather with high peel strength and a preparation method thereof are disclosed. According to the disclosure, a renewable and durable antibacterial waterborne polyurethane emulsion is coated on release paper to obtain a polyurethane surface layer, and the polyurethane surface layer is adhered to the surface of a surface-modified base fabric to obtain a base fabric containing the polyurethane layer; and then chlorination is performed to obtain the renewable antibacterial waterborne polyurethane synthetic leather with high peel strength. The halamine antibacterial monomer used in the disclosure has antibacterial renewability and is connected with an ultraviolet absorbent, so that the antibacterial durability of a polyurethane coating is improved.

Described herein is a process for preparing polyurethane sheet/laminate with reduced bubbles, including the steps of applying a polyurethane system obtained by mixing an isocyanate component (A) and a polyol composition component (B) to form a base coat layer, where the components (A) and (B) are kept separately in tanks under vacuum before mixing, and the application of the polyurethane system is implemented via knife coating under relative humidity of 65% or below. Further described herein are a polyurethane sheet/laminate prepared by the described process and a synthetic leather made from the polyurethane sheet/laminate.

A method for producing a support for polyurethane-based imitation leather free of dimethylformamide or other solvents or water involves preparing a base. A two-component polyurethane layer is sprayed on the base which includes preparing a first component and a second component. The first and second components are combined to obtain a mixture, and the mixture is sprayed uniformly on the base forming the polyurethane layer. A backing is applied on the two-component polyurethane layer forming a support and the support is dried.

A PVC slurry for manufacturing a PVC artificial leather, comprising a PVC resin, a plasticizer, a viscosity reducer, and a stabilizer, wherein the viscosity reducer comprises a wetting dispersant and an aliphatic hydrocarbon solvent with a boiling point in the range of 100 C.-250 C. is disclosed. The PVC slurry further relates to a PVC artificial leather, comprising a PVC skin layer prepared from the PVC slurry of the present invention.

A manufacturing method of a wear-resistant artificial leather includes forming a modified thermoplastic polyolefin film and laminating the modified thermoplastic polyolefin film onto a substrate to form a first laminate structure, forming a polyurethane layer on a release paper and then forming an adhesive layer on the polyurethane layer to form a second laminate structure, attaching the adhesive layer of the second laminate structure to the modified thermoplastic polyolefin film of the first laminate structure, removing the release paper to expose the polyurethane layer, and forming a silicon-containing water-based polyurethane surface layer on the polyurethane layer to obtain the wear-resistant artificial leather.
