WATER VAPOR-PERMEABLE COMPOSITE MATERIAL
A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 μm, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 μm. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.
COMPOSITION, SHEET-SHAPED MOLDED BODY, ARTIFICIAL LEATHER, AND MANUFACTURING METHOD OF SHEET-SHAPED MOLDED BODY
An object of the present invention is to provide a composition capable of realizing an excellent matt tone of a leather surface in a case of being used as a synthetic leather or an artificial leather, a sheet-shaped molded body, an artificial leather, and a manufacturing method of a sheet-shaped molded body. The composition of the present invention is a composition used for a synthetic leather or an artificial leather, the composition containing a polypeptide, a fibrous substance other than the polypeptide, and, a plasticizer.
ECO-FRIENDLY AUTOMOTIVE INTERIOR PART AND METHOD OF MANUFACTURING SAME
Proposed are an eco-friendly automotive interior part, a method of manufacturing the same, and a method of designing the same automotive interior part. The automotive interior part can not only optimally correct physical properties thereof using manufacturing and design methods, but also have eco-friendliness by significantly reducing harmfulness to the human body due to the minimized use of chemicals, while realizing natural wrinkles resembling those of natural leather.
Process for Manufacturing Non-Woven Fabric-Like Composite Materials from Shredded Polymer-Coated Paper Products and Coffee Grounds
The invention relates to a process for producing non-woven fabric-like composite materials, novel non-woven fabric-like composite materials, articles made therefrom and their use. In particular the fabric-like composite materials are derived from shredded polymer-glued or polymer-coated paper products and coffee grounds as raw material.
PORTABLE DRY RECREATIONAL SLIDE
A portable dry recreational slide is configured to be easily carried by a single person when in a compacted state and expanded into a deployed state in a remote location as desired. The dry recreational slide, when deployed, is elongated and includes a low-friction sliding surface upon which a rider may slide without application of water, oil, soap or any other temporary lubricant. The dry slide comprises a slide body having a lightweight, flexible substrate coated with a low-friction material.
Water-repellent and lipophilic composite needle-punched nonwoven fabric and preparation method thereof
The invention relates to a water-repellent and lipophilic composite needle-punched nonwoven fabric and a preparation method thereof. The method comprises the following steps: blending a PET fiber and a polyolefin-based fiber in a mass ratio of 3:1-1:3, and performing needle punching to obtain a composite needle-punched nonwoven fabric; carrying out hot-drying treatment on the composite needle-punched nonwoven fabric at 110-160° C. for 40-90 min; and carrying out water-repellent finishing on the hot-dried fabric using 50-70 mL/L of an aqueous solution of a modified resin-based fluorine-free waterproofing agent, and drying to obtain the water-repellent and lipophilic composite needle-punched nonwoven fabric, wherein the water-repellent finishing is dip rolling, the air pressure is 1.8 kPa and the liquid carrying rate is 160-230%. The preparation method of the invention is simple, and the prepared composite needle-punched nonwoven fabric has significantly improved water repellency, lipophilicity and tensile strength compared with the fabric before treatment.
Latex composition
A latex composition having a nitrile rubber containing an α,β-ethylenically unsaturated nitrile monomer unit and a conjugated diene monomer unit, wherein the nitrile rubber has a weight average molecular weight of 50,000 to 100,000, and the weight of methanol extractables in all solids present in the latex composition is 2 to 20 wt % based on the weight of all the solids.
STRETCH NONWOVENS AND FILMS
Elastic polymer compositions that provide stretch recovery to absorbent fabrics and products produced from these absorbent fabrics and methods for their production are provided.
METHOD OF PRODUCING A SUPPORT FOR POLYURETHANE-BASED IMITATION LEATHER FREE OF DIMETHYLFORMAMIDE (DMFA) OR OTHER SOLVENTS OR WATER, AND RELATED METHOD OF PRODUCING AN IMITATION LEATHER
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.
AIRLAID NONWOVEN
Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
