Embodiment 1

[0024] A hydrophobic anti-ultraviolet fabric, the base material of the fabric has a hydrophilic surface, graphene oxide and aminopropyl isobutyl silsesquioxane are supported on the fabric.

[0025] The base material is cotton.

[0026] Described hydrophobic anti-ultraviolet fabric is made by following method:

[0027] (1) Using natural flake graphite as raw material, graphene oxide is prepared by the improved Hummers method, wherein, the improved Hummers method refers to the literature: Marcano D.C., et al., Improved synthesis of graphene oxide, ACS Nano, 4(2010), 8, The method in pp.4806-4814 is carried out.

[0028] (2) 0.2 g of graphene oxide powder was ultrasonically dispersed in 200 mL of aqueous solution to obtain a graphene oxide dispersion with a concentration of 1 mg / mL. The cotton fabric was immersed in the above graphene oxide dispersion, the finishing time was 3 hours, and the finishing temperature was 70°C. After washing with water and drying, the graphene oxid...

Embodiment 2

[0031] The difference from Example 1 is that the concentration of the graphene oxide dispersion is 3 mg / mL, and a hydrophobic and UV-resistant fabric is prepared.

Embodiment 3

[0033] The difference from Example 1 is that the concentration of the aminopropyl isobutyl silsesquioxane dispersion is 2.5 mg / mL, and a hydrophobic and UV-resistant fabric is prepared.

Abstract

The invention discloses a hydrophobic anti-ultraviolet fabric and a preparation method thereof. A base material of the fabric has a hydrophilic surface, and the fabric is loaded with graphene oxide and aminopropyl isobutyl silsesquioxane. In the preparation method disclosed by the invention, the graphene oxide and the aminopropyl isobutyl silsesquioxane are jointly used for preparing a functional fabric for the first time, thereby endowing the hydrophilic base material of the fabric with hydrophobic and anti-ultraviolet properties, and improving the application value of the fabric; and preparation method disclosed by the invention only adopts a two-step finishing process to obtain a fluorine-free hydrophobic fabric with excellent performance. The preparation method is easy and flexible, green and environmentally friendly, and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a functional fabric, in particular to a hydrophobic and ultraviolet-resistant fabric and a preparation method thereof. Background technique [0002] Inspired by the hydrophobic effect on the surface of lotus leaves, it has always been a research hotspot to prepare textiles with hydrophobic function using fabrics as substrates. Fabrics with hydrophobic surfaces can be used in waterproof, self-cleaning, oil-water separation and other fields. However, fabrics such as cotton, silk and other structures contain a large number of hydrophilic groups, making the fabrics very hydrophilic. In addition, the gaps between fabric fibers and the fluff on the surface have brought great difficulties to the hydrophobic finishing of fabrics. Generally, there are two ways to prepare fabrics with hydrophobic function, one is to construct nano-micron substances on the surface of the fabric to increase ...
