Description

Technical Field

[0001] The invention relates to the technical field of fabrics, in particular to a nano silver ion antibacterial and deodorizing textile fabric and a preparation process thereof. Background Art

[0002] Antibacterial fabrics are generally made antibacterial by infiltrating silver ions into the fabric. Ordinary fabrics sprayed with antibacterial coatings lose a large amount of silver ions after multiple washings, and their antibacterial ability is significantly reduced. Reducing the loss rate of silver ions in the fabric is a problem that needs to be solved.

[0003] The defects of existing fabrics are: 1. Prior art JP2008111221A discloses an antibacterial fabric. In this technology, the antibacterial agent is impregnated into the fabric fiber. After multiple washings, the antibacterial agent in the fabric is easily lost in large quantities with the water, causing a sharp decrease in the antibacterial ability. Therefore, a nano silver ion antibacterial and deodorizing textile fabric that reduces the loss rate of the antibacterial agent is needed to solve this problem.

[0004] 2. The prior art US06780799B2 discloses an antibacterial fabric. This technology does not have a structure to reduce the impact of the antibacterial agent in the fabric during washing. The antibacterial agent in the fabric is easily washed away quickly due to the rapid and continuous impact of the water flow on the fabric during washing. Therefore, a nano silver ion antibacterial and deodorizing textile fabric that can reduce the impact frequency of the antibacterial silver ions in the fabric is needed to solve this problem.

[0005] 3. The prior art US09494387B2 discloses an antibacterial fabric. This technical fabric does not have a supporting structure in the middle, and the air in the fabric is easily squeezed out, thereby reducing the insulating air content and causing the thermal insulation performance of the fabric to deteriorate. Therefore, a nano silver ion antibacterial and deodorizing textile fabric with a supporting structure to ensure that a sufficient amount of air is retained in the fabric is needed to solve this problem.

[0006] 4. Prior art CN112144278B discloses antibacterial fabrics, which do not have the function of regulating humidity. Clothing made of the fabrics cannot regulate the humidity on the skin surface. Too high or too low humidity on the skin surface can easily cause adverse effects on the skin. Therefore, a nano silver ion antibacterial and deodorizing textile fabric that can regulate the humidity on the skin surface is needed to solve this problem. Summary of the invention

[0007] One purpose of the present application is to provide a nano silver ion antibacterial and deodorizing textile fabric and a preparation process thereof, which can solve the technical problems raised in the prior art.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a nano silver ion antibacterial and deodorizing textile fabric, which comprises, from bottom to top, a fiber layer one, a corrugated film layer, a fiber layer two, a cotton swab, a humidity-conditioning block and an antibacterial block, wherein the multiple cotton swabs are arranged in a bottom groove of the corrugated film layer, the multiple humidity-conditioning blocks are arranged on a top raised portion of the corrugated film layer, the antibacterial block is arranged in a groove at the top of the corrugated film layer, and the antibacterial block is composed of activated carbon and nano silver ions.

[0009] Preferably, the fiber layer 1 is woven from spandex fibers.

[0010] Preferably, the second fiber layer is woven from spandex fibers.

[0011] Preferably, the cotton swab is made of cotton fiber.

[0012] Preferably, the humidity-conditioning block is formed by mixing diatom mud, plastic and a foaming agent.

[0013] Preferably, the weight ratio of diatom mud, plastic and foaming agent in the humidity control block is (10-20): (20-40): (1-2).

[0014] Preferably, the plastic is one of polyethylene or polyvinyl chloride.

[0015] Preferably, the corrugated film layer is in a corrugated shape and is made of a polyethylene film or a polyvinyl chloride film.

[0016] Preferably, the preparation process of the nano silver ion antibacterial and deodorizing textile fabric is as follows: S1, weaving spandex fiber into fabric, and then laying the spandex fiber fabric on a substrate to form a fiber layer 1; S2, gluing the cotton swabs at equal intervals on the top of the fiber layer by point gluing to form cotton swabs; S3, gluing the polyethylene film to the top of the fiber layer 1 by point gluing, and forming the polyethylene film into a corrugated shape, so that the cotton swab is located in the groove at the bottom of the corrugated polyethylene film, thereby forming a corrugated film layer; S4, soaking the activated carbon particles in the silver ion bactericidal agent, then taking out the activated carbon particles and evenly sprinkling them in the top groove of the corrugated film layer, then putting the substrate, the fiber layer 1 and the corrugated film layer into a heating box and heating them to 110° C.-140° C., so that the activated carbon particles adhere to the groove of the molten corrugated film layer to form an antibacterial block; S5. Place 20-40 parts of polyethylene particles, 10-20 parts of diatom mud and 1-2 parts of foaming agent into a dispensing machine with a stirring and heating structure for heating, melting and mixing. Then dispense the molten liquid on the top raised part of the corrugated film layer to form a humidity control block.

[0017] Preferably, the step S5 further includes the following steps: S51, weaving spandex fibers into fabrics, and then gluing the spandex fabrics onto the corrugated film layer by point gluing to form a second fiber layer.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention absorbs silver ions through activated carbon, and makes polyethylene melt-adhesive activated carbon, so as to adsorb silver ions. When the fabric is washed with water, the activated carbon can effectively adsorb silver ions, thereby reducing the loss rate of silver ions in the fabric during washing, and the activated carbon is not easy to fall off, so that the fabric can withstand more times of washing and still maintain good antibacterial and deodorizing capabilities.

[0019] 2. The present invention adheres activated carbon to a corrugated film layer in a corrugated shape, so that the fabric can be loosely folded when washed. The folding of the corrugated film layer reduces the impact of water flow on the activated carbon, thereby reducing the loss of silver ions in the activated carbon, making the silver ion loss rate of the fabric slower when washed. When worn on a person, the fabric is tensioned and the corrugated film layer is stretched, so that sweat can enter the grooves of the corrugated film layer and contact the activated carbon, thereby releasing the silver ions for sterilization.

[0020] 3. The cotton swab provided in the present invention can support the corrugated film layer, so that a certain amount of air is maintained inside the fabric, thereby making the fabric have a good thermal insulation effect through the air.

[0021] 4. The humidity-regulating block provided in the present invention can effectively reduce the loss of diatom mud during washing by mixing plastic and diatom mud and making the plastic present a porous structure, thereby enabling the fabric to absorb moisture under humid conditions and release moisture under dry conditions, thereby enabling the fabric to regulate the humidity of the skin and avoid excessive dryness or excessive moisture of the skin.
