摘要:
The present invention concerns a method for coating a textile material with a silicone elastomer composition crosslinkable by condensation reactions, to produce a solid silicone elastomer, optionally in a thin layer, on a flexible support that can be made from a textile material, paper, polyvinyl chloride, polyester, polypropylene, polyamide, polyethylene, polyurethane, non-woven glass fibre fabric or polyethylene terephthalate.

Provided is a base body for an artificial leather comprising a polyester excellent in thermostability during melt molding. That is, provided is a conjugated fiber comprising a polyester which exhibits only a small reduction in intrinsic viscosity during melt molding. The base body for an artificial leather comprises an intertwined fiber body mainly comprising an ultrafine fiber having a 0.01 to 10 µm fiber diameter and an elastic polymer, the ultrafine fiber comprising, as a constituent polymer, a polyester obtained from a dicarboxylic acid and/or an ester-forming derivative thereof, and a diol, the polyester containing 15 to 500 ppm of a 1,2-propanediol-derived component.
摘要:
The invention relates to a multi-layer façade film, comprising a nonwoven fabric layer made of a nonwoven fabric and a film layer made of a plastic film, wherein the nonwoven fabric layer and the film layer are connected to one another. According to the invention: the nonwoven fabric is arranged between two film layers as a middle layer, is made of a thermoplastic elastomer, is elastically extendible in one direction, and is designed as a melt-blown product; each film layer is also elastically extendible in one direction, contains an elastically deformable thermoplastic urethane designated as TPU, and is connected to the nonwoven fabric as an extrusion coating; and the façade film has a yield strength of at least 40% in the longitudinal direction and in the transverse direction, a tensile strength, with respect to a 50 mm wide film strip, of at least 120 N, a maximum s d value of 1.5 m in terms of the vapor permeability of the façade film, and a value corresponding to a water column of at least 8 m in terms of the water impermeability of the façade film.
