Embodiment 1

[0189] in figure 2 Reports on the reflectance spectra of multilayer materials obtained according to the present invention.

[0190] The multilayer material includes a support layer 1 of microfibers formed of 50% PU and 50% Pa, and has a thickness "d" of 0.9 mm + / - 0.05 mm.

[0191] The support layer 1 of microfibers has been dyed with a dyeing solution including about 6% by weight of the first coloring compound in a dry state relative to the weight of the microfibers to be dyed.

[0192] The multilayer material includes a polyurethane cover layer 2 having a thickness "d1" of 0.06 mm + / - 0.03 mm.

[0193] The cover layer 2 has been colored with 10% by weight of the second coloring compound relative to the weight of the polyurethane composition to be colored.

[0194] From figure 2 From the analysis of the figure, it can be seen that the multilayer material of this example has low reflection and high absorption in the visible light wavelength (400-700nm), and therefore is perceived as...

Abstract

A multilayer material (100) comprises at least a support layer of coagulated microfiber (1) and at least a cover layer (2) made of polyurethane applied by spreading on said support layer of coagulatedmicrofiber (1), characterised in that said support layer of coagulated microfiber (1) and said cover layer (2) comprise one or more colouring compounds suitable for giving to said support layer (1) and to said cover layer (2) a dark coloration, said one or more colouring compound being so adjusted to obtain a multilayer material (100) having a reflectance greater than 60%, preferably greater than75%, in a greatly preferred manner greater than 80%, and in a maximally preferred manner greater than 85% in the infrared wavelength.

Description

Technical field [0001] The present invention relates to multi-layer materials, and in particular to a novel multi-layer material having a support layer of microfibers and a covering layer of polyurethane. [0002] The material of the present invention is particularly intended to be used in the fields of shoe uppers, outdoor furniture, and automobile equipment. [0003] In particular, the material of the present invention is suitable for motorcycle and bicycle saddles. [0004] The present invention particularly relates to multilayer materials, which are particularly intended to produce materials with a leather appearance, commonly known as artificial leather. [0005] The present invention particularly relates to multi-layer materials, which are intended to be used as coverings in the furniture field, for textiles, decoration (decoration) parts such as sofas, chairs, etc., and as covering materials for the field of auto parts. [0006] The material of the present invention is also parti...
