摘要:
A method for making a polyurethane coated fabric, the method comprising:— a) providing a fabric liner; b) applying a coating to at least part of the liner, said coating comprising a polyurethane resin and manganese ferrite dissolved in a polar aprotic solvent; c) at least partially gelling the coating with water or an aqueous solution, so that the polar aprotic solvent is extracted from the coating; d) leaching the at least partially gelled coating with water or an aqueous solution, so as to further reduce the level of the polar aprotic solvent in the coating; and e) drying and curing the coating. The coating may also contain a dark colour pigment. A composition suitable for use in the method is also provided. The method enables polyurethane coated fabric products, such as gloves, to be produced which are black or grey in colour and contain a reduced amount of residual polar aprotic solvent, such as N,N-dimethylformamide.

A knitted glove comprises: at least one finger component, an upper palm component, a thumb component, a lower palm component, and a wrist component wherein each of the components comprises courses and each course is made of stitches, wherein each of the courses of the upper palm component includes a tuck knit stitch adjacent the upper palm inner edge and each of the courses of the thumb component includes a tuck knit stitch adjacent the thumb inner edge, such that the glove has a tuck knitted ridge along the upper palm inner edge, around the thumb crotch and along the thumb inner edge. The knitted glove has high strength in the thumb crotch area and is useful as a protective glove. The tuck knitted ridge provided in the glove not only increases the safety of the wearer but also increases the useful working life of the glove. Also provided is a method of making the knitted glove. The glove is knitted on a flat knitting machine.

Fabrics are disclosed having a liner with a polymeric coating, the coating comprising 0.25 to 8 ridges per cm and pits at an area density of 20 to 2500 cm2. The fabrics provide good friction in oily conditions. Also dis-closed are methods for producing such fabrics comprising applying to a liner a liquid comprising water and a precursor of a polymeric material, contacting the liquid on the liner with a water-sorbing material and curing the polymeric coating. The fabrics may fmd use in gloves.
摘要:
A polyurethane-coated fabric product, particularly a polyurethane-coated glove, comprises a fabric liner and, on the surface of the liner, a microporous foam layer comprising polyurethane and a bifunctional sulphur-containing alkoxysilane. The microporous foam layer exhibits increased abrasion resistance, durability and increased resistance to water penetration. Preferably, the bifunctional sulphur-containing alkoxysilane is bis(triethoxysilylpropyl)tetrasulphane. The polyurethane-coated fabric product is manufactured by a method comprising the steps: (a) providing a fabric liner; (b) applying a coating to at least part of the surface of the liner, wherein the coating comprises a solution, in a polar aprotic solvent, of a polyurethane resin and a bifunctional sulphur-containing alkoxysilane; (c) treating the coated fabric with water, thereby causing the polyurethane to coagulate and form a microporous foam layer on the fabric liner; and (d) drying the polyurethane-coated fabric product.

摘要:
An embodiment is disposed of a method of making gloves, more particularly polyvinyl chloride (PVC) coated gloves. The method comprises providing a liner, and coating at least a part of the liner with a PVC paste to form a coating having an outer layer, applying particles of a soluble solid to the outer layer of the coating and curing the outer layer. Preferably, the method further comprises gelling the outer layer after applying the particles and contacting the gelled outer layer with a solvent before curing. Preferable, the soluble solid comprises a solid acid.
