Description
Technical Field
The invention belongs to the technical field of spinning, and relates to a functional fabric, in particular to a hydrophobic anti-ultraviolet fabric and a preparation method thereof.
Background
Inspired by the hydrophobic effect of the surface of lotus leaves, the textile with the hydrophobic function is prepared by taking the textile as a base material, and is always a hot point of scientific research. The fabric with the hydrophobic surface can be applied to the fields of water prevention, self cleaning, oil-water separation and the like. However, fabrics such as cotton, silk and the like contain a large number of hydrophilic groups in the structure, so that the fabrics have strong hydrophilicity. In addition, the gaps between the fibers of the fabric, the fluff on the surface and the like all bring great difficulty to the hydrophobic finishing of the fabric. Generally, there are two approaches to prepare fabrics with hydrophobic function, one is to construct nano-micron material on the surface of the fabric to improve the surface roughness of the fabric, and the other is to construct a layer of low surface energy material on the surface of the fabric.
The fluorine-containing hydrophobic finishing agent has excellent performance and is the most commonly used hydrophobic finishing agent. The fabric finished by the fluorine-containing hydrophobic finishing agent has excellent hydrophobic property, and can keep good hand feeling, air permeability and moisture permeability. However, the fluorine-containing finishing agent has great harm to human health and is being banned worldwide. Therefore, it is urgently needed to find a hydrophobic finishing agent with excellent performance and environmental protection to replace a fluorine-containing hydrophobic finishing agent.
The organic silicon substance is also an efficient hydrophobic finishing agent, and the combination of the organic silicon substance and the fabric can effectively reduce the surface energy of the fabric, thereby improving the hydrophobic property of the fabric. Aminopropyl isobutyl silsesquioxane is a novel organic silicon substance, and the surface energy of the fabric can be effectively reduced by combining the aminopropyl isobutyl silsesquioxane with the fabric, so that the hydrophobic property of the fabric is improved. However, the surface of the fabric has few groups capable of being combined with aminopropyl isobutyl silsesquioxane, so that the fabric has to be modified to a certain extent, and the fabric with more and abundant functional groups can effectively adsorb the aminopropyl isobutyl silsesquioxane on the surface. Graphene, as an inorganic carbon material, has high hydrophobic capability, and the combination of graphene and fabric can effectively reduce the surface energy of the fabric, thereby improving the hydrophobic property of the fabric. However, graphene has no affinity with the fabric and cannot be directly adsorbed to the fabric surface.
Disclosure of Invention
The technical problem to be solved is as follows: in order to overcome the defects of the prior art, reduce the surface energy of hydrophilic fabrics and endow the hydrophilic fabrics with more functionality, the invention provides a hydrophobic ultraviolet-resistant fabric and a preparation method thereof.
The technical scheme is as follows: a hydrophobic ultraviolet-resistant fabric, wherein a substrate of the fabric is provided with a hydrophilic surface, and graphene oxide and aminopropyl isobutyl silsesquioxane are loaded on the fabric.
Preferably, the substrate is cotton or silk.
A method of making a hydrophobic uv resistant fabric, the method comprising the steps of:
(1) preparing graphene oxide by adopting an improved Hummers method, dispersing graphene oxide powder in water, and preparing a graphene oxide dispersion liquid;
(2) soaking the fabric into the graphene dispersion liquid prepared in the step (1), stirring to enable graphene oxide to be fully adsorbed to the surface of the fabric, washing with water, and drying to obtain a graphene oxide finished fabric;
(3) dispersing aminopropyl isobutyl silsesquioxane powder in absolute ethyl alcohol to obtain aminopropyl isobutyl silsesquioxane dispersion liquid, soaking the finished fabric obtained in the step (2) in the aminopropyl isobutyl silsesquioxane dispersion liquid, stirring to enable aminopropyl isobutyl silsesquioxane to be fully adsorbed on the surface of the fabric, then sequentially washing with ethyl alcohol and water, and drying to obtain the hydrophobic ultraviolet-resistant fabric.
Preferably, in the step (1), the concentration of the graphene oxide dispersion liquid is 1mg/mL-3 mg/mL.
Preferably, in the step (2), the finishing time in the graphene oxide dispersion liquid is 1-4 hours, and the finishing temperature is 50-80 ℃.
Preferably, in the step (2), the finishing time in the graphene oxide dispersion liquid is 3 hours, and the finishing temperature is 70 ℃.
Preferably, the aminopropyl isobutyl silsesquioxane dispersion in step (3) has a concentration of 1.0mg/mL to 2.5 mg/mL.

Preferably, in step (3), the finishing time in the aminopropyl isobutyl silsesquioxane dispersion is 2 hours and the finishing temperature is 60 ℃.
The principle of the preparation of the hydrophobic ultraviolet-resistant fabric is as follows: graphene oxide is a derivative of graphene, and the surface of graphene oxide has a large number of and abundant oxygen-containing functional groups (carboxyl, hydroxyl, epoxy, etc.), so that graphene oxide has good affinity with a fabric, and can be directly adsorbed to the surface of the fabric. The surface energy of the fabric is obviously reduced due to the graphene oxide adsorbed on the surface, so that the hydrophobic capacity of the fabric is improved. After finishing by graphene oxide, the aminopropyl isobutyl silsesquioxane is combined with the fabric more easily and tightly, so that the surface energy of the fabric is further reduced, and the hydrophobic capacity of the fabric is improved. In addition, the fabric after twice finishing can simultaneously absorb short-wave ultraviolet rays with the wavelength of less than 281nm and reflect long-wave ultraviolet rays with the wavelength of more than 281nm, so that the fabric has excellent ultraviolet resistance.
Has the advantages that: (1) according to the method, the graphene oxide and the aminopropyl isobutyl silsesquioxane are jointly used for preparing the functional fabric for the first time, so that the hydrophobic and ultraviolet-resistant performances of the hydrophilic fabric substrate are endowed, and the application value of the fabric is improved; (2) the method only adopts a two-step finishing method to obtain the fluorine-free hydrophobic fabric with excellent performance, is simple, flexible, green and environment-friendly, and is suitable for mass production.
