Description

Method for improving adhesion of titanium dioxide on cotton fabric and self-cleaning effect
Technical Field
The invention relates to a method for improving the attachment of titanium dioxide on cotton fabric and the self-cleaning effect, and belongs to the technical field of textile printing and dyeing.
Background
After the photocatalyst material is applied to textiles, the photocatalyst material can be endowed with a photocatalytic function, and further self-cleaning functions of degrading volatile organic compounds, removing peculiar smell, resisting bacteria, preventing fouling and the like are obtained. Nano TiO 22The material is a material with photocatalytic performance, has unique surface effect, small-size effect, quantum size effect, macroscopic quantum tunneling effect and the like, presents a plurality of special optical and electronic characteristics, becomes an ideal material for degrading dyes and auxiliaries and preparing antibacterial and self-cleaning textiles in the textile field, and becomes a research hotspot of the textile industry in recent years.
TiO2Has little affinity with textile fiber, and combines nano TiO with the textile fiber2There are two main methods for applying to textiles: one is to mix TiO2Blending and spinning with spinning solution to produce textile, the method is only suitable for synthetic fiber; another method is to use nano TiO2The dispersion is used for padding or coating finishing of the fabric to achieve the effect, and the method is simple and easy to implement. However, due to the nano TiO2Small grain size, high specific surface energy, poor particle dispersibility, easy agglomeration, low attachment amount on the fabric, and limited washing fastness, hand feeling and the like of the finished fabric.
Disclosure of Invention
In the invention, TiO is mixed with2Dispersed in mixed solution containing butanetetracarboxylic acid, tetradecyltrimethylammonium chloride and sodium hypophosphite, and used for finishing cotton fabric pretreated by caustic soda/urea, so that TiO can be effectively and synergistically improved2Adhesion and self-cleaning ability.
The invention comprises the following processes:
(1) preparing TiO with the mass fractions of 2 percent, 6 percent, 0.4 percent and 4 percent2Butanetetracarboxylic acid, tetradecylPerforming ultrasonic treatment on the mixed dispersion liquid of trimethyl ammonium chloride and sodium hypophosphite for 30min at room temperature;
(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 butanetetracarboxylic acid, tetradecyltrimethylammonium chloride and sodium hypophosphite2The dispersion was mixed. Butane tetracarboxylic acid and tetradecyltrimethyl ammonium chloride can be used in synergy with TiO2Surface modification is carried out to improve the dispersing ability in solution and improve TiO2The force between the cotton fabric and the cotton fabric is helpful for improving the adhesion and the self-cleaning capability. The butane tetracarboxylic acid and the sodium hypophosphite play a role in the subsequent attachment of the nano TiO to the fabric2The 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 for2、The butane tetracarboxylic acid and tetradecyl trimethyl ammonium chloride compound enters the cotton fabric more deeply, and the attachment amount and the self-cleaning capacity of the compound are further improved in a synergistic manner. Finally, the cotton fabric is soaked in TiO2Mixing the dispersion solution for 30min, taking out, dewatering, drying the fabric at 80 deg.C, heating to 170 deg.C, and baking for 2 min.
