Abstract

A composite textile is provided. The composite textile includes a textile substrate and a thermal material layer formed on the textile substrate. The thermal material layer includes a nanocomposite powder. The nanocomposite powder is composed of a pyrrolidone-containing polymer and an inorganic particle. The pyrrolidone-containing polymer is polyvinylpyrrolidone, a derivative of polyvinylpyrrolidone or a combination thereof. The inorganic particle is a metal oxide composed of a first metal M A , a doping metal M B and oxygen. The inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.

First claim

What is claimed is:

1. A composite textile, comprising:
a textile substrate; and
a thermal material layer formed on the textile substrate, wherein the thermal material layer comprises a nanocomposite powder, and the nanocomposite powder consists of:
a pyrrolidone-containing polymer, wherein the pyrrolidone-containing polymer is a derivative of polyvinylpyrrolidone or a combination of the derivative of polyvinylpyrrolidone and a polyvinylpyrrolidone, wherein the derivative of polyvinylpyrrolidone comprises a polyvinylpyrrolidone having an isocyanate group at a terminal, a polyvinylpyrrolidone having a methoxy group at a terminal, a polyvinylpyrrolidone having an ethoxy group at a terminal, a polyvinylpyrrolidone having a carboxylic acid group at a terminal, or a combination thereof; and
an inorganic particle, wherein the inorganic particle is a metal oxide composed of a first metal M A , a doping metal M B and oxygen;
wherein the inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.

2. The composite textile as claimed in claim 1 , wherein the metal oxide is represented by formula (I):
(M A )(M B )O  (I)

wherein the first metal M A is zinc, indium, or tin; and the doping metal M B is tin, aluminum, gallium, iron, or antimony.

3. The composite textile as claimed in claim 2 , wherein a content of the doping metal M B is 0.1-20 parts by weight, based on 100 parts by weight of the first metal M A in the inorganic particle.

4. The composite textile as claimed in claim 1 , wherein a median particle diameter D50 of the nanocomposite powder is 30-600 nm.

5. The composite textile as claimed in claim 1 , wherein a weight average molecular weight of the pyrrolidone-containing polymer is 3,000-1,500,000.

6. The composite textile as claimed in claim 1 , wherein the thermal material layer further comprises a polymer carrier.

7. The composite textile as claimed in claim 6 , wherein the polymer carrier comprises a polyurethane, a polyacrylonitrile, a polyvinylidene fluoride, a polyacrylate, a polypropylene, a polyamide, a polyester, a thermoplastic polyester elastomer, or a combination thereof.

8. The composite textile as claimed in claim 6 , wherein the polymer carrier is 0.1-60 parts by weight, based on 100 parts by weight of the nanocomposite powder in the thermal material layer.

9. The composite textile as claimed in claim 1 , wherein the nanocomposite powder is 0.0001-600 parts by weight, based on 100 parts by weight of the textile substrate.

10. The composite textile as claimed in claim 1 , wherein the thermal material layer is a thin film.

11. The composite textile as claimed in claim 10 , wherein a thickness of the thin film is 1-100 μm.

12. The composite textile as claimed in claim 10 , wherein a light transmittance of the thin film is 70-83% under conditions in which a wavelength is in the range of 400-700 nm and a thickness of the thin film is 6 μm.

13. The composite textile as claimed in claim 10 , wherein a light absorption of the thin film is 70-83% under conditions in which a wavelength is in the range of 1,000-2,500 nm and a thickness of the thin film is 6 μm.

14. The composite textile as claimed in claim 1 , wherein the textile substrate comprises a polyethylene fiber textile, a polypropylene fiber textile, a polyamide fiber textile, a polyester fiber textile, a cellulose fiber textile, an acetate fiber textile, an animal fiber textile, or a combination thereof.
