Antibacterial and anti-mite window curtain fabric

Abstract

This utility model discloses an antibacterial and anti-mite curtain fabric, comprising a composite base fabric layer, a heat insulation layer, and an acrylic fabric layer. A zinc oxide nanofilm layer is attached to the surface of the base fabric layer away from the heat insulation layer; a nano-titanium dioxide film layer is attached to the surface of the acrylic fabric layer away from the heat insulation layer. The zinc oxide nanofilm used in this antibacterial and anti-mite curtain fabric allows the metal oxide to directly react with the bacterial cell membrane and intracellular substances, thereby achieving an antibacterial and anti-mite effect. The titanium dioxide nanofilm used on the other surface has antibacterial and UV-protective effects, which can extend the service life of the inner fabric. The heat insulation layer reduces heat exchange between the two sides of the curtain fabric.

Description

Technical Field

[0001] This utility model relates to an antibacterial and anti-mite curtain fabric, belonging to the field of curtain fabric technology. Background Technology

[0002] Curtains, as an essential household item, serve to block sunlight and beautify, decorate, and prevent others from peeping in. With the development of textile technology, a wide variety of curtain styles are now available on the market, far exceeding people's aesthetic needs. However, due to varying living environments, various bacteria and mites from outdoors can easily enter indoors via air and rainwater. Furthermore, indoor temperatures, especially in the humid environment of southern regions, make curtain fabrics a breeding ground for bacteria and mites, posing a significant threat to the health of residents. Therefore, developing an antibacterial and mite-proof curtain fabric has become a problem to be solved. Utility Model Content

[0012] The markings in the diagram are explained as follows: 1-Base fabric layer; 2-Insulation layer; 3-Acrylic fabric layer; 4-Zinc oxide nanofilm layer; 5-Nano titanium dioxide film layer; 6-TPU light-shielding film. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1 Combination Figure 1 and Figure 2 This embodiment will be described in detail below. The antibacterial and anti-mite curtain fabric involved in this embodiment includes a composite base fabric layer 1, a heat insulation layer 2, and an acrylic fabric layer 3; specifically, the layers are composited by a PU hot melt adhesive mesh film, and the areal density of the PU hot melt mesh film used is 10 grams per square meter.

[0015] A zinc oxide nanofilm layer 4 is attached to the surface of the base fabric layer 1 away from the heat insulation layer 2; a nano-titanium dioxide film layer 5 is attached to the surface of the acrylic fabric layer 3 away from the heat insulation layer 2. The zinc oxide nanofilm layer 4 and the nano-titanium dioxide film layer 5 are formed by vacuum deposition technology, directly depositing multiple layers of nanoscale metals or metal oxides onto the fabric surface to create a nanofilm. When bonded to the fabric, they form strong chemical bonds, exhibiting water resistance and abrasion resistance. Furthermore, due to their nanofilm nature, they also possess waterproof and stain-resistant properties, allowing stains and dust on the curtain fabric surface to be removed with a gentle wipe. In this embodiment, the thickness of the zinc oxide nanofilm layer 4 and the nano-titanium dioxide film layer 5 is approximately 50 nm.

[0016] The titanium dioxide used in the nano-titanium dioxide film layer 5 is a photocatalyst. When excited by ultraviolet light and illumination, titanium dioxide generates a large number of electrons, which react with water and oxygen adsorbed on the fabric surface to produce highly oxidizing hydroxyl radicals. These hydroxyl radicals can efficiently degrade toxic and harmful gases in the air (such as formaldehyde, ammonia, benzene, nitrogen oxides, sulfur oxides, VOCs, etc.), destroy bacterial cell membranes and solidify viral proteins, effectively killing various bacteria (such as Escherichia coli, Staphylococcus aureus, influenza viruses, etc.), with an antibacterial rate as high as 99.99%. Furthermore, through oxidation-reduction reactions, it can decompose and harmlessly treat organic pollutants such as toxins and musty odors released by bacteria or mold into pollution-free carbon dioxide and water, thus achieving antibacterial, sterilization, and odor elimination functions. In addition, the titanium dioxide used also has UV protection properties, giving the knitted fabric both antibacterial and UV-protective functions.

[0017] The zinc oxide nanofilm layer 4 is a thin film formed by nano-sized zinc oxide particles, and zinc oxide has good antibacterial and anti-mite capabilities.

[0018] Furthermore, the base fabric layer 1 includes a bottom comb, a middle comb, and a top comb; the yarn used in the top comb is 75D / 72F copper-modified antibacterial and anti-mite PA6 fiber yarn; the middle comb and bottom comb use 70D hollow polyester filament. The copper-modified antibacterial and anti-mite PA6 fiber yarn is formed by adding copper antibacterial agent to PA6 chips and then melt spinning. Testing has shown it to have good antibacterial effects. The hollow polyester filament, due to its hollow structure, provides thermal insulation. The areal density of base fabric layer 1 is 220 grams per square meter.

[0019] Furthermore, the padding yarn number of the bottom comb is 1-0 / 2-3 / / ; the padding yarn number of the middle comb is 1-2 / 1-0 / / ; and the padding yarn number of the face comb is 4-5 / 1-0 / / . The weaving process of the three-comb warp-knitted fabric gives it excellent tear resistance.

[0020] Furthermore, the heat insulation layer 2 includes a hollow fiber fabric layer 21 and a silica aerogel coating 22 disposed on both sides of the hollow fiber fabric layer 21. The heat insulation layer 2 is formed by coating both sides of the hollow fiber fabric layer 21 with silica aerogel, thereby forming a silica aerogel coating 22 with a thickness of 1 mm. The aerogel material has good heat insulation effect, thus giving the curtain fabric a heat insulation effect.

[0021] Furthermore, the hollow fiber fabric layer 21 is a planar three-dimensional fabric woven from hollow polyester filaments at a 60° angle, with an areal density of 80 grams per square meter. Unlike two-dimensional woven fabrics with a 90° angle, the planar three-dimensional fabric has better tear resistance.

[0022] Furthermore, the acrylic fabric layer 3 is woven from 20-count acrylic yarn using a warp-knitted plain weave, with a surface density of 100 grams per square meter. The thermal conductivity of this embodiment was tested using ASTM D1518, and the result was 0.018 m. 2 With a thermal conductivity of 0.0228 m²·K / M, it exhibits excellent heat insulation properties. The antibacterial properties of the curtain fabric prepared in this embodiment were tested using ATCC 6538, showing an inhibition rate of over 97% against Escherichia coli and 99% against Staphylococcus aureus. Even after five washes, it still maintains a thermal conductivity of 0.0228 m²·K / M and an antibacterial rate of over 95%. The UPF value of the curtain fabric prepared in this embodiment was tested according to GB / T 18830—2009 "Evaluation of Ultraviolet Protection Performance of Textiles," reaching 85+, indicating excellent UV protection.

[0023] Example 2 Combination Figure 3 This embodiment will be described in detail below. The antibacterial and anti-mite curtain fabric involved in this embodiment has a TPU blackout film 6 laminated to the side of the base fabric layer 1 near the heat insulation layer 2, providing better blackout effect.

[0024] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
