Abstract
Description
Technical Field
[0001] This invention relates to the field of fabric technology, specifically to a fabric based on bamboo charcoal and lavender for sterilization and purification. Background Technology
[0002] Knitted fabrics, classified by weaving method, are divided into two categories: weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics typically use low-elastic polyester yarn or profiled polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., as raw materials, employing plain knit structures, varied plain knit structures, rib knit structures, double rib knit structures, jacquard structures, terry knit structures, etc., woven on various weft knitting machines. However, the internal structure of existing fabrics is relatively simple, resulting in poor heat retention and antibacterial properties, thus limiting the fabric's applicability. Summary of the Invention
[0003] The purpose of this invention is to provide a fabric based on bamboo charcoal and lavender for sterilization and purification, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A fabric based on bamboo charcoal and lavender for sterilization and purification includes an antibacterial layer; a flame-retardant layer is provided on the lower side of the antibacterial layer; a base layer is provided at the bottom of the flame-retardant layer; an electrostatic adsorption layer is provided on the other side of the base layer; a bamboo charcoal and lavender layer is provided at the bottom of the electrostatic adsorption layer; and a waterproof layer is provided at the bottom of the bamboo charcoal and lavender layer.
[0006] As a further aspect of the present invention: the bamboo charcoal lavender layer has a lavender layer inside; the lavender layer is filled with lavender fragrance microcapsules, and the lavender fragrance is contained in the polymer membrane layer to form aromatic microcapsules by utilizing the coagulation effect of polymers. Under the action of physical friction and rupture, the micropores of the capsule wall allow the fragrance of lavender fragrance to be slowly released, thereby purifying the air.
[0007] As a further aspect of the present invention: antibacterial strips are embedded inside the moisture-absorbing layer, the surface of the moisture-absorbing layer is woven into a mesh, and the thickness of the moisture-absorbing layer is less than that of the base layer, which facilitates the moisture-absorbing layer to improve the moisture absorption effect of the fabric.
[0008] As a further embodiment of the present invention: the antibacterial layer includes a first antibacterial layer and a second antibacterial layer; the first antibacterial layer is made of nano-titanium dioxide, and the second antibacterial layer is made of chitosan nano-silver.
[0009] As a further aspect of the present invention: the waterproof layer is a JRP vacuum nano-coating. The JRP vacuum nano-coating waterproof layer has good waterproof properties. Compared with ordinary waterproof coatings, the JRP vacuum nano-coating effectively blocks the penetration of water.
[0010] As a further aspect of the present invention: the base layer is a nylon fabric layer containing carbon elements, which enhances the heat storage capacity of the base layer.
[0011] A method for preparing a fabric base layer based on bamboo charcoal and lavender for sterilization and purification includes the following steps:
[0012] Step 1: Add organic nano-montmorillonite with a particle size of 10-200 nm to a titanate coupling agent solution with a concentration of 0.1-5%, stir for 1-3 hours, filter, and dry at 50-120℃ to obtain modified organic nano-montmorillonite; add activated carbon powder with a particle size of 0.01-1 mm to a carbon nanotube solution with a concentration of 0.1-2%, stir for 2-3 hours, filter, and dry at 80-150℃ to obtain modified activated carbon powder;
[0013] Step 2: Add the modified organic nano-montmorillonite and modified activated carbon powder obtained in Step 1 to the polyimide sol, wherein the total added mass of modified organic nano-montmorillonite and modified activated carbon powder is 1-5% of the mass of the polyimide sol, and disperse them evenly to obtain the modified polyimide sol.
[0014] Step 3: Immerse a quartz felt with a thickness of 0.5-1 mm and a density of 0.1-0.3 g / cm3 in the modified polyimide sol obtained in Step 2. After immersion for 1-2 hours, remove the quartz felt and dry it using a supercritical drying method to obtain the modified polyimide aerogel felt.
[0015] Step 4: Using polyurethane foam with a porosity of 80-90% and a thickness of 0.5-1mm as the upper and lower layers, and the modified polyimide aerogel felt obtained in Step 3 as the middle layer, cut the upper, middle, and lower layers to the same size, and then sew the upper, middle, and lower layers together with polyester thread. The stitch density is 1-8 stitches / square centimeter. When sewing, ensure that the shrinkage rate in the thickness direction is within the range of 5-30% to obtain the air purification fabric core material.
[0016] Step 5: Using the air purification fabric core material obtained in Step 4 as the middle layer, and meltblown polyester nonwoven fabric with a thickness of 0.2-1 mm and a porosity of 60-90% as the upper and lower layers, wherein the fiber fineness of the meltblown polyester nonwoven fabric ranges from 1 to 10 micrometers; after the upper, middle and lower layers are cut to the same size, the upper, middle and lower layers are sewn together with polyester thread, with a sewing density of 0.5-3 stitches / square centimeter, and the shrinkage rate in the thickness direction is ensured to be within the range of 2-10% during sewing, to obtain the base fabric.
[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1-3 In this embodiment of the invention, a cloth based on bamboo charcoal and lavender for sterilization and purification includes an antibacterial layer 1; a flame-retardant layer 2 is provided on the lower side of the antibacterial layer 1; a base layer 4 is provided at the bottom of the flame-retardant layer 2; an electrostatic adsorption layer 5 is provided on the other side of the base layer 4; a bamboo charcoal and lavender layer 6 is provided at the bottom of the electrostatic adsorption layer 5; and a waterproof layer 7 is provided at the bottom of the bamboo charcoal and lavender layer 6.
[0025] The bamboo charcoal lavender layer 6 has a lavender layer inside; the lavender layer is filled with lavender fragrance microcapsules. By utilizing the coagulation effect of polymers, the lavender fragrance is contained in the polymer membrane to form aromatic microcapsules. Under the action of physical friction and rupture, the micropores in the capsule wall of the microcapsule allow the fragrance of the lavender fragrance to be slowly released, which plays a role in purifying the air.
[0026] The moisture-absorbing layer 3 has antibacterial strips 301 embedded inside, and the surface of the moisture-absorbing layer 3 is woven into a mesh. The thickness of the moisture-absorbing layer 3 is less than that of the base layer 4, which makes it easier for the moisture-absorbing layer 3 to improve the moisture absorption effect of the fabric.
[0027] The antibacterial layer 1 includes a first antibacterial layer and a second antibacterial layer; the first antibacterial layer is made of nano-titanium dioxide, and the second antibacterial layer 8 is made of chitosan nano-silver. Under the action of ultraviolet light, nano-titanium dioxide produces a strong catalytic degradation function, which can effectively degrade toxic and harmful gases in the air and effectively kill a variety of bacteria. After the silver ions in chitosan nano-silver come into contact with bacteria, they cause damage to the inherent components of microorganisms or cause functional disorders. When the bacteria lose their activity, the metal ions will be released from the bacteria and repeat the bactericidal activity, so its antibacterial effect is long-lasting.
[0028] The waterproof layer 7 is a JRP vacuum nano-coating. The JRP vacuum nano-coating waterproof layer 7 has good waterproof performance. Compared with ordinary waterproof coatings, the JRP vacuum nano-coating effectively blocks water penetration.
[0029] The base layer 4 is a nylon fabric layer containing carbon elements, which enhances the heat storage capacity of the base layer 4.

The vertical axis with a horizontal axis of zero represents the initial toluene concentration in the experiment, and the vertical axis at the end of the curve represents the toluene concentration at the end of the purification experiment. As can be seen from the data in the graph, the purification rate exceeded 90% after 200 minutes of the five experiments.

[0036] Step 3: Immerse a quartz felt with a thickness of 0.5-1 mm and a density of 0.1-0.3 g / cm3 in the modified polyimide sol obtained in Step 2. After immersion for 1-2 hours, remove the quartz felt and dry it using a supercritical drying method to obtain the modified polyimide aerogel felt.
[0037] Step 4: Using polyurethane foam with a porosity of 80-90% and a thickness of 0.5-1mm as the upper and lower layers, and the modified polyimide aerogel felt obtained in Step 3 as the middle layer, cut the upper, middle, and lower layers to the same size, and then sew the upper, middle, and lower layers together with polyester thread. The stitch density is 1-8 stitches / square centimeter. When sewing, ensure that the shrinkage rate in the thickness direction is within the range of 5-30% to obtain the air purification fabric core material.
[0038] Step 5: Using the air purification fabric core material obtained in Step 4 as the middle layer, and meltblown polyester nonwoven fabric with a thickness of 0.2-1 mm and a porosity of 60-90% as the upper and lower layers, wherein the fiber fineness of the meltblown polyester nonwoven fabric ranges from 1 to 10 micrometers; after the upper, middle and lower layers are cut to the same size, the upper, middle and lower layers are sewn together with polyester thread, with a sewing density of 0.5-3 stitches / square centimeter, and the shrinkage rate in the thickness direction is ensured to be within the range of 2-10% during sewing, to obtain the base fabric.
