The textile composite comprises a microfiber outer layer; a nonwoven layer, and in some embodiments a porous polymeric membrane on a support layer.

This invention relates a compostable lid for sealing a beverage capsule or a beverage pad wherein the lid comprises a natural-fiber based support obtainable by: (i) providing a first fibrous base sheet comprising natural fiber material sensitive to a gelatinizing agent; (ii) treating the first base sheet with a gelatinizing agent to give a treated first fibrous base sheet comprising gelatinized material; (iii) providing a second fibrous base sheet; (iv) contacting the treated first fibrous base sheet and the second base sheet with each other; (v) causing at least partial migration of the gelatinized material from the treated first fibrous base sheet into the second fibrous base sheet to give a multilayer product; and (vi) neutralizing and/or washing the product thus obtained and then drying it.

Disclosed is a preparation method for a copper clad laminate comprising: (1) dissolving a polymer in an organic solvent, heating and stirring to obtain a pre-impregnation liquid; (2) impregnating a liquid crystal polymer cloth in the pre-impregnation liquid, and drying to obtain a liquid crystal polymer impregnated cloth; and (3) laminating the liquid crystal polymer impregnated cloth and a copper foil to prepare the copper clad laminate, wherein the polymer in step (1) is at least one selected from the group consisting of fully aromatic polyesteramide, epoxy resin, and polyimide; and the liquid crystal polymer cloth in step (2) is prepared from a liquid crystal polymer having a melting point greater than 280° C., a dielectric constant less than 3.2, and a dielectric loss tangent angle less than 0.0025. The preparation method for the copper clad laminate has a simple preparation process and a low manufacturing cost.

An artificial leather includes a resin layer as the surface and a base fabric connected to the resin layer as the substrate. The base fabric comprises at least two monolayer structures arranged in an orderly manner as two laminates. Each monolayer structure is woven with some of the warp yarns and/or weft yarns in such layer or with some of the warp yarns and/or weft yarns in one or more other layers to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other in the weaving process, forming a multi-layer integrated base fabric. The artificial leather incorporates a number of air vent holes distributed in the resin layer and the base fabric in the direction of thickness while retaining mechanical properties of tensile strength and tear resistance.

The present disclosure provides for composite textiles that can include a coating layer that is compatible with textiles such as those comprising polyolefins. The coating layer, as well as the precursor coating layer composition, the coating mixture, or resin composition used to form the coating layer, include a mixture of a polyolefin resin and a thermoplastic vulcanizate (TPV). It is believed that the use of the coating layer in the disclosed composite textiles can promote better bonding between other components or materials used in articles, such as articles of footwear or articles of clothing, while resisting or preventing creasing and bagging. This allows the use of cost-effective materials such as polyolefins in the composite textiles that have adequate physical and mechanical properties, while also having sufficient chemical bonding properties.

A stitch-bonded tape or other directionally stabilized product wherein stitch-bonding is carried out by overstitching yarns stitched through a sheeting or other surface substrate in conjunction with the introduction of high tenacity lay-in yarn elements disposed longitudinally in the machine direction of formation to provide strength in the length direction. The overstitching yarns secure the lay-in yarns in place relative to the surface substrate. An adhesive or other coating is disposed in covering relation to the lay-in yarn elements.

A method of manufacturing a metal-clad laminate and uses of the same are provided. The method comprises the following steps: (a) impregnating a reinforcement material with a first fluoropolymer solution, and drying the impregnated reinforcement material under a first temperature to obtain a first prepreg; (b) impregnating the first prepreg with a second fluoropolymer solution, and drying the impregnated first prepreg under a second temperature to obtain a second prepreg; and (c) laminating the second prepreg and a metal-clad to obtain a metal-clad laminate, wherein the first fluoropolymer solution has a first fluoropolymer, the second fluoropolymer solution has a second fluoropolymer, and the first fluoropolymer and the second fluoropolymer are different.

A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance a.sub.1 of 0.01 to 0.12; a second resin member which has an absorbance a.sub.2 of 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance a.sub.3 of 0.2 to 3.8, and the absorbances a.sub.2, a.sub.3 exhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.
