example 1

[0013] At room temperature, put the nanometer titanium dioxide into distilled water, stir well to make a 40g / L nanometer titanium dioxide and water mixture; then put 20g polyester fabric into 400mL nanometer titanium dioxide and water mixture, vigorously shake for 20min , Make the polyester fabric evenly adhere to the nano-titanium dioxide, then take out the fabric and irradiate it with UV light under an 800W ultraviolet lamp. A layer of sponge soaked in water is placed under the fabric to prevent the polyester fabric from being dried quickly. The polyester fabric is 40cm in length. After 10 minutes of ultraviolet radiation, the polyester fabric is taken out, and then immersed in a mixture of nano-titanium dioxide and water for 5 minutes. At the same time, the sponge is also replenished with water. Then the polyester fabric is irradiated with ultraviolet light for 10 minutes, and repeat until the ultraviolet light irradiation time When it reaches 60min, take out the polyester fa...

Abstract

The invention relates to an ultraviolet nano-grade preparation method of super-hydrophilicity terylene fabric. According to the invention, nano-grade titanium dioxide is adhered to the surface of terylene fabric; the terylene fabric is irradiated by using ultraviolet rays, such that the surface of the terylene fabric is rapidly oxidized, and the terylene fabric is provided with super-hydrophilicity. Traditionally, only ultraviolet irradiation is adopted; and a water contact angle is reduced when the terylene fabric is irradiated for 700min. With the method provided by the invention, the terylene fabric is irradiated for 60min, and can be turned into super-hydrophilicity terylene fabric. As a result of experiments, a water contact angle is 0 DEG.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a method for preparing ultra-hydrophilic polyester fabric with ultraviolet nano-titanium dioxide. Background technique [0002] Polyester fabric is the most important fabric in chemical fibers, accounting for about 60% of chemical fibers. Its good crispness and wrinkle elasticity make polyester widely used in the textile industry and industrial textiles. [0003] However, the hydrophilicity of polyester fabric is very poor, and the contact angle of water is very large. Therefore, there are many research reports on the hydrophilic finishing and modification of polyester fabrics. Such as alkali reduction treatment on the surface of polyester, grafting protein to improve the hydrophilicity of polyester fabrics; or etching with plasma, oxidation with potassium permanganate, etc., by giving hydrophilic groups on the surface of polyester fabrics to improve The hydrophili...
