Abstract

Articles comprising multiple layers are included. The multiple layer articles may include fabrics or foams in combination with a polyurethaneurea composition such as a film or an aqueous dispersion.

Claims (23)

1 . An article comprising multiple layers comprising:

(a) at least two layers; and

(b) at least one polyurethaneurea film, applied or laminated or bonded to an apparel fabric; wherein said film is cast from an aqueous polyurethaneurea dispersion that is substantially organic solvent free; and wherein said dispersion comprises % NCO of about 1.8 to about 2.6, and further wherein said dispersion comprises a prepolymer comprising

(i) at least one polyol selected from polyethers, polyesters, polycarbonates, and combinations thereof, wherein the polyol has a number average molecular weight of 600 to 3500;

(ii) a polyisocyanate; and

(iii) at least one diol compound.

2 . The article of claim 1 , wherein the film is between the at least two layers.

3 . The article of claim 1 , wherein said at least two layers are selected from the group consisting of (a) two fabric layers, (b) two foam layers, (c) a fabric layer and a foam layer, and combinations thereof.

4 . The article of claim 1 , wherein said at least two layers include at least two fabric layers and at least two foam layers.

5 . The article of claim 4 , wherein the film is adjacent to a foam layer on each side and each foam layer is adjacent to a fabric layer.

6 . The article of claim 1 , wherein the article is molded.

7 . The article of claim 1 , wherein the article is pressed.

8 . The article of claim 1 , wherein the film extends throughout the entire area of the multiple layer article.

9 . The article of claim 1 , wherein the film extends to a portion of the area of the multiple layer article.

10 . The article of claim 1 , wherein at least two polyurethaneurea films are included.

11 . The article of claim 1 , wherein said polyurethaneurea dispersion comprises a polymer having a weight average molecular weight from about 40,000 to about 150,000.

12 . The article of claim 1 , wherein said polyurethaneurea dispersion comprises a polymer having a weight average molecular weight from about 100,000 to about 150,000.

13 . The article of claim 1 , wherein said polyurethaneurea dispersion comprises a polymer having a weight average molecular weight from about 120,000 to about 140,000.

14 . The article of claim 1 , wherein said film is porous.

15 . The article of claim 1 , wherein said film is perforated.

16 . The article of claim 1 in the form of a garment.

17 . The article of claim 3 , further comprising an adhesive between two or more layers.

18 . The article of claim 17 , wherein said adhesive is a hot melt adhesive, a contact adhesive, a thermoset, a thermoplastic, or a polyurethaneurea aqueous dispersion.
