Method for the Production of a Microporous Polymer Coated Fabric
The present inventions relates to a low solvent based method for the production of a microporous polymer coated fibrous fabric, comprising the steps of contacting the fabric with a composition dispersed in an aqueous medium thereby coating the fabric with the composition, and contacting the coated with a coagulation solution and drying of the fabric, crosslinking the polymer resin. Furthermore, the present invention relates to a cleaning cloth comprising a microporous polymer coating obtained by the method.
SKIN MATERIAL AND METHOD FOR PRODUCING SKIN MATERIAL
A skin material containing, in the following order: a base fabric that is configured to contain fibers having a synthetic resin coating layer, wherein fibers adjacent to each other in the base fabric are at least partially fused with each other; and an adhesive layer and a skin layer, which are provided at a surface of at least one side of the base fabric in this order from the base fabric, the skin material having a plurality of ventilation holes passing through the skin material in a thickness direction.
COMPOSITE SKIN MATERIAL FOR VEHICLE AND METHOD FOR MANUFACTURING THE SAME
A composite skin material for a vehicle wherein a synthetic leather includes a surface resin layer having a plurality of openings, an adhesion layer present on the rear surface of the surface resin layer, and a fibrous base material present on the rear surface of the surface resin layer across the adhesion layer, and the adhesion layer is present only at the adherend part, except for the plurality of openings, in the rear surface of the surface resin layer, and the base material surface of the fibrous base material is bonded to the surface resin layer.
ARTIFICIAL LEATHER FOR CRASH PADS AND CRASH PADS MANUFACTURED USING THE SAME
Disclosed are an artificial leather for crash pads and a crash pad manufactured using the same. The artificial leather for crash pads may have improved workability when workers directly cover a crash pad with the artificial leather for crash pads and require reduced manufacturing costs by using a textile substrate layer made of a circular knit fabric that satisfies a specific physical property range.
Glove
A glove according to the present invention includes a glove body configured to cover a hand of a wearer. The glove body has an outermost layer including a matrix resin and cellulose particles and constituting an outer surface of the glove. The outermost layer includes the cellulose particles in the range of more than 1 part to 9 parts or less by mass based on 100 parts by mass of the matrix resin. At least some of the cellulose particles are at least partially exposed from the outer surface.
Glove having durable ultra-thin polymeric coating
A thin, abrasion resistant supported glove, including a knitted liner and a polymeric layer disposed on and within individual strands of yarns of the knitted liner, are disclosed. Methods for manufacturing the thin, abrasion resistant supported glove are also disclosed.
METHOD FOR MAKING A COATED FABRIC
A method for making a coated fabric includes the steps of: applying a coating solution of a resin in an organic solvent to a roller-conveyed non-stretchable and releasable substrate web to form a coating layer; laminating a roller-conveyed base fabric to the coating layer to form a laminate; guiding the laminate to pass through at least one tank containing water to immerse the laminate in water such that the coating layer is solidified and the organic solvent contained in the coating layer is replaced by water; and removing water from the coating layer by drying to leave micropores in the coating layer.
LAYERED MATERIAL AND METHOD FOR PRODUCING A LAYERED MATERIAL
The invention relates to a method for producing a surface-structured layered material which has a backing layer (I) and a polyurethane layer (2) connected thereto, the backing layer (I) used, in particular in pieces, being a leather, preferably a smoothed full-grain leather or a split cowskin, a textile material, preferably a woven fabric or a knitted fabric, a cellulose fibre material, a split foam, a leather fibre material or a microfibre fleece and being connected to the layer (2), and the layer (2) applied to the backing layer (I) being at least one, preferably a single layer formed of a PU foam, in particular containing gas pockets, preferably a whipped PU foam optionally containing hollow microspheres and/or a PU foam containing hollow microspheres. According to the invention: —the PU foam, in particular containing gas pockets, is created with a PU dispersion mixture, wherein the individual PU dispersions used to create the PU dispersion mixture exhibit different softening points in the dry state; —to create the PU dispersion mixture, one or more PU dispersions having heat—preferably melting and contact adhesive properties and a softening point in the dry state greater than 40° C., preferably greater than 45° C., in an amount of 18 to 52 wt ¾ of the finished PU dispersion mixture is/are mixed with one or more PU dispersions without melting and contact adhesive properties and with a softening point greater than 95° C., preferably greater than 125° C., in an amount of 39 to 73 wt ¾ of the finished PU dispersion mixture; —the PU dispersion mixture for the layer (2) is applied to the backing layer (I) with a thickness such that the layer has a thickness in the dried state of 0.075 to 0.450 mm, preferably 0.150 to 0.280 mm; —before or during structuring of the PU foam, a further layer (3) of a non-foamed PU dispersion which is a mixture of multiple PU dispersions is applied to the layer (2); —the backing layer (I) is optionally cut or punched into banks or pattern parts before or after the application of the PU foam, in particular after the drying thereof, and the coated blanks or pattern parts are subjected to stamping or structuring under pressure and temperature; and —the backing layer (1), the further layer (3) and the layer (2) are compressed and joined to one another and structured with a die (4) under application of a contact pressure of 4 to 48 kg/cm2, preferably 4 to 48 kg/cm2, in particular 18 to 25 kg/cm2.
COATED BARRIER FABRIC FOR A REUSABLE MEDICAL PRODUCT
A coated barrier fabric for use in a reusable medical product (e.g., surgical gown, surgical drape, etc.) is provided and has two woven or knitted plies. Each of the two plies are coated on one side with a non-fluorine containing polymer and retain similar comfort and feel of uncoated woven or knitted fabrics. The coated sides of the plies face each other (i.e., inwardly) in the interior of the barrier fabric. Because of the orientation of the plies, the coated sides of the plies can come into direct contact with and move freely against each other within the interior of the barrier fabric. The coating on each of the plies is protected from exterior and environmental factors, including repeated institutional laundering/autoclave cycles, that could abrade and degrade the coating. Thus, the useful life of the reusable medical product including the barrier fabric is extended.
SYNTHETIC RESIN SKIN MATERIAL AND MANUFACTURING METHOD THEREOF
A synthetic resin skin material and a manufacturing method thereof, the synthetic resin skin material including, in this order: a base fabric; a thermoplastic resin layer having a storage elastic modulus at 160° C. of 2,000,000 Pa or less measured in accordance with JIS K 7244 (1998); and a skin layer containing a urethane resin, wherein the synthetic resin skin material has recesses at a side of the skin layer, the recesses having a depth, in a thickness direction of the synthetic resin skin material, that extends from the skin layer as far as an inner part of the thermoplastic resin layer, past a boundary that is present between the skin layer and the thermoplastic resin layer at a non-recessed region.
