Abstract

The invention discloses a photocatalytic self-cleaning fabric and a preparation method thereof. The fabric is mainly prepared from, by mass, 65-80 parts of polyvinyl chloride, 10-15 parts of polyethylene terephthalate, 4-10 parts of sliver-loaded nano TiO2, 2-6 parts of nano SiO2, 2-6 parts of disodium hydrogen phosphate dodecahydrate, 3-6 parts of polystyrene sulfonate, 3-5 parts of cellulose ester, 8-13 parts of benzyl butyl phthalate, 2-5 parts of nano zinc oxide, 2-5 parts of nano cuprous oxide, 0.1-0.3 part of a defoaming agent, 0.4-1.2 parts of chitosan, 0.3-1 part of an emulsified wetting agent, 2-5 parts of sodium alginate and 0.5-1.5 parts of ester gum. The photocatalytic self-cleaning fabric is simple in process, easy to industrialize and suitable for application and popularization. Self-cleaning of the fabric can be achieved under visual light; the preparation method makes the combination of a photocatalyst and the fabric stronger and more durable and is simple and easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation and self-cleaning finishing, and in particular relates to a photocatalytic self-cleaning fabric and a preparation method thereof. Background technique [0002] The functionalization of textiles is a research hotspot in the field of textile technology in recent years, mainly through the introduction of functional organic or inorganic nanomaterials to endow fabrics with certain functionality. Among many functional additives, photocatalysts can undergo oxidation-reduction reactions and photoreactions with their surface adsorbates under the participation of light, and become a more promising material in the study of textile functionalization. [0003] Nano-TiO 2 It is one of the commonly used photocatalysts. It has the characteristics of non-toxic, tasteless, non-irritating, high chemical stability, strong ability to absorb ultraviolet rays, and high visible light transmittance. Under the ...
