Chinese Patent Publication No. CN 202878845U, published on April 17, 2013, named "An Antibacterial Composite Fabric". The antibacterial composite fabric is composed of PU leather layer, bamboo charcoal fiber layer and cloth layer, wherein, The bamboo charcoal fiber layer is filled with nano-silver particles, and the prepared fabric has good antibacterial effect, excellent softness and tensile strength, but after the fabric is exposed to oil, its self-cleaning effect is poor, which will also affect the antibacterial ability
Chinese Patent Publication No. CN 204869854U, date of publication is December 16, 2015, titled "anti-fouling and corrosion-resistant antibacterial composite fabric", the method adopts wool layer, bamboo charcoal fiber layer, antibacterial layer, corrosion-resistant layer, antifouling layer Synthesis, the prepared fabric layer can ensure the antibacterial effect of the fabric, and at the same time have antifouling and corrosion resistance, but the preparation of each functional surface layer needs to be modified, the process is relatively complicated, the cost is high, and the tea production efficiency is low
Chinese Patent Publication No. CN 204049151U, the publication date is December 31, 2014, and the name is "antibacterial carpet", mainly by coating the surface of the fabric carpet with a silicon dioxide anti-oxidation layer and a photocatalyst layer in order to make the carpet antibacterial under the action of visible light. Achieve antibacterial effect, effectively purify indoor air, and have self-cleaning ability at the same time, but the functional layer coated on the surface of carpet fabric is prone to peeling and falling off, thereby reducing antibacterial and self-cleaning ability

Abstract

The invention relates to a preparation method of a fluff surface layer used for carpets and having self-cleaning antibacterial effect, and belongs to a textile material surface treatment technology. According to the present invention, a fluff surface layer is ultrasonically cleaned sequentially with an organic solvent and deionized water, and a functional nanometer ZnO thin film and a functional nanometer Al2O3 film are sequentially deposited on the surface of the cleaned fluff surface layer, such that the fluff surface layer of the carpet has characteristics of self-cleaning property and antibacterial property; with the prepared fluff surface layer, the fluff surface layer has advantages of broad-spectrum antibacterial function, good thermal stability and good mechanical stability, and the fluff surface layer of the carpet is endowed with the self-cleaning effect so as to significantly improve the stain resistance and the flame retardant performance, such that the durability is good,the service life of the carpet is effectively prolonged, and the broad application prospect is provided.

Description

Technical field: [0001] The invention relates to a method for preparing a fleece surface layer with self-cleaning and antibacterial effects for carpets, which belongs to the surface treatment technology of textile materials. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to the health and comfort of the living environment. Carpet, as a soft decoration for home life, has been widely used in living rooms, bedrooms and other environments. received great attention.
