Abstract

The invention discloses a preparation method of an anti-ultraviolet cotton fabric. The method comprises the following steps: (1) mixing tetrabutyl titanate, anhydrous ethanol and glacial acetic acid according to a certain volume ratio, performing magnetic stirring for 30-40 min, then adding a 1 mol / L acid solution, carrying out boiling refluxing 2-5 h, and adjusting the pH value of the obtained solution to 6.8-7.2 in order to obtain a titanium dioxide sol; (2) taking a certain amount of the titanium dioxide sol, adding deionized water to dilute the titanium oxide sol until the concentration ofthe titanium oxide sol is 0.02-0.1 mol / L, adding an appropriate amount of nanometer titanium dioxide powder, and performing ultrasonic dispersion for 5-8 h to obtain an anti-ultraviolet finishing agent; and (3) carrying out alkali washing and desizing on a cotton fabric sample, airing the sample, immersing the sample in the anti-ultraviolet finishing agent, carrying out anti-ultraviolet finishingon the cotton fabric sample by a "double impregnating and double padding" process, drying the impregnated and padded cotton fabric sample at 80-100 DEG C for 5-8 min, and performing high temperaturebaking at 110-130 DEG C for 2-5 min to obtain the anti-ultraviolet cotton fabric. The cotton fabric has a good anti-ultraviolet performance, and can meet the long-term anti-ultraviolet requirement.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for preparing an anti-ultraviolet cotton fabric. Background technique [0002] Pure cotton fabric has good moisture absorption and moisture permeability, soft hand feeling and comfortable to wear, especially pure cotton poplin is a high-grade clothing fabric, usually used as high-grade shirt fabric. However, as a summer clothing fabric, the main problem is that the anti-ultraviolet and antibacterial properties are not ideal. In order to improve the anti-ultraviolet and antibacterial properties of pure cotton fabrics, functional finishing must be carried out on pure cotton fabrics. [0003] In recent years, as people's requirements for living standards have become higher and higher, while enjoying life comfortably, a large amount of fluorine and chlorine compounds have been discharged into the atmosphere, causing the ozone layer to be severely damaged day by day. The am...
