Description

Method for improving attachment capacity and ultraviolet resistance of titanium dioxide on cotton fabric
Technical Field
The invention relates to a method for improving the attachment of titanium dioxide on cotton fabric and the ultraviolet resistance, and belongs to the technical field of textile printing and dyeing.
Background
The protection by using the ultraviolet-proof fabric is one of important means for protecting human bodies against ultraviolet ray. With the increasing concern of people on health and environmental problems, the development and application of various ultraviolet-resistant textiles are rapidly developed. The production method of the ultraviolet-proof fabric mainly comprises two production ways: one is to add ultraviolet screening agent to make ultraviolet resistant fiber during polymerization or spinning, then to produce ultraviolet resistant fabric through spinning, weaving, etc. the method has the advantage of less influence on the product style, but only suitable for synthetic fiber. The other is shielding with ultraviolet raysThe agent is used for padding or coating finishing of fabrics to achieve the protection effect, and the method is simple and easy to implement. Nano TiO 22The ultraviolet screening agent is one of the most commonly used ultraviolet screening agents, has the characteristics of no toxicity, no odor, no irritation, high chemical stability, strong ultraviolet absorption capability, high visible light transmittance and the like, has wide application prospect, and is a research hotspot in the textile industry in recent years. However, due to the nano TiO2The particle size is small, the specific surface energy is high, the particle dispersibility is poor and easy to agglomerate, the binding force with the surface of the fabric is weak, so that the attachment amount on the fabric is low, and the fastness to washing, the hand feeling and the like of the finished fabric are limited to a certain extent.
Disclosure of Invention
In the invention, TiO is mixed with2Fully dispersed in a mixed solution containing citric acid, tetradecyltrimethyl ammonium chloride and sodium hypophosphite, and used for finishing cotton fabrics pretreated by caustic soda/urea, thereby effectively and synergistically improving TiO2The amount of adhesion and the ultraviolet resistance.
The invention comprises the following processes:
(1) preparing TiO with the mass fractions of 2 percent, 6 percent, 0.4 percent and 4 percent2Mixing the dispersion liquid of citric acid, tetradecyl trimethyl ammonium chloride and sodium hypophosphite, and performing ultrasonic treatment at room temperature for 30 min;
(2) preparing a mixed solution of 7% of sodium hydroxide and 12% of urea by mass, putting a cotton fabric into the mixed solution, refrigerating the cotton fabric at the temperature of minus 10 ℃ for 1 hour at the mass ratio of 1:50, and then washing the cotton fabric to be neutral;
(3) soaking the cotton fabric washed to be neutral in the mixed dispersion liquid for 30min, then taking out the cotton fabric for dehydration, drying the cotton fabric at 80 ℃, heating to 170 ℃ and baking for 2 min.
Firstly, preparing TiO containing citric acid, tetradecyl trimethyl ammonium chloride and sodium hypophosphite2The dispersion was mixed. Citric acid and tetradecyltrimethyl ammonium chloride can be used for synergistic effect on TiO2Surface modification is carried out to improve the dispersing ability in solution and improve TiO2The acting force between the adhesive and the cotton fabric is helpful for improving the adhesion and the ultraviolet resistance. The citric acid and the sodium hypophosphite are used for subsequent attachment to the fabricOf nano TiO2The fixation is performed. The mixed solution of 7 percent by mass of sodium hydroxide and 12 percent by mass of urea is used for refrigerating the fabric at the temperature of minus 10 ℃, so that the internal micro-gap of the cotton fiber is enlarged, the structure becomes loose, and the TiO is helpful for2The citric acid and the tetradecyl trimethyl ammonium chloride compound enter the cotton fabric more deeply, and the attachment amount and the ultraviolet resistance of the cotton fabric are further improved in a synergistic manner. Finally, the cotton fabric is soaked in TiO2Mixing the dispersion liquid for a certain time, dewatering the fabric after the transfer and adhesion are finished, drying the fabric at 80 ℃, heating to 170 ℃ and baking for 2min, and finishing the whole adhesion and fixation process.
