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 provides a preparation method for a permanently antibacterial fluff surface layer used for a carpet and relates to the preparation technology of the carpet. According to the preparationmethod for the permanently antibacterial fluff surface layer used for the carpet, first the fluff surface layer is subjected to ultrasonic cleaning by using an organic solvent and deionized water in order, and a functional nanometer ZnO film of a specific thickness is deposited on the cleaned fluff surface layer by using an atom layer deposition technology. Because the function nanometer film is bonded to the surface of the fluff surface layer through chemical bonds, the fluff surface layer of the invention has good chemical stability, is free of secondary pollution and free of irritancy, is safety and nontoxic, and enables the long-acting wide spectrum antibacterial effect to be realized; and the processed fluff surface layer of the carpet does not change, to a certain degree, the intrinsic characteristics of material such as the softness, luster, comfort and air permeability of the material, and has a wide application prospect.

Description

Technical field: [0001] The invention relates to a method for preparing a permanent antibacterial fluff surface layer for carpets, which belongs to the carpet preparation technology. Background technique [0002] Carpet is a flooring material made of wool, cotton, hemp or chemical synthetic fibers by hand or mechanism. As a soft decoration for home life, it has entered all aspects of the living environment, and multifunctional carpets have become more and more popular. The more people like it, especially the carpets with excellent effects such as antibacterial have received great attention. At present, the carpets with antibacterial effect mainly adopt the post-processing finishing type, and generally the surface of the carpet fiber material is modified. 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...
