Abstract
Description
The present invention relates to a method of weaving an antimicrobial fabric using silver nano, and more particularly, to a method of weaving a silver nano yarn and a synthetic resin yarn produced by a yarn improvement method so as to have an antibacterial action in the yarn itself, The present invention relates to a method of weaving an antimicrobial fabric using silver nano.
Various kinds of textile products are contaminated with microorganisms by the use or storage defects, or by the contact with the human body, the microorganisms grow and multiply by the secretion of human body as a nutrient source, Not only deteriorates the quality such as fastness, but also threatens the health of the human body.
For these reasons, fibers imparted with functions such as far-infrared radiation, antibacterial, antistatic, ultraviolet shielding, deodorization and deodorant, which are beneficial to the human body, are being developed.
The method of imparting the above-described various functionalities to the fibers can be largely classified into a post-treatment method and a yarn improvement method. First, there are methods of imparting antimicrobiality by extracting a dye component from a natural substance and heat-fixing or adsorbing an antimicrobial substance such as an organic metal compound or an organic substance to the fiber surface by cross-linking the fiber. In the method of improving the yarn, there is a method of mixing the inorganic antibacterial agent with the polymer in the manufacturing step of the synthetic fiber to incorporate it in the fiber, and a method of synthesizing the polymer by making an organic copolymerization component having antibacterial property.
Of course, processing to inhibit the growth and propagation of bacteria or fungi on the fiber should be absolutely safe for the human body while maintaining the antimicrobial effect at a level higher than the high antimicrobial activity. In this sense, the organometallic compounds used in the post-treatment process have excellent bactericidal properties, but they have problems such as human stability due to toxicity. In addition, these organometallic compounds have problems such as adhesion to fibers and durability to washing, and thus they have limitations in that they have permanent or continuous antibacterial properties.
These organic antimicrobial materials are easier to process than inorganic ones and do not greatly affect mechanical properties, transparency, and color. However, as mentioned above, the antimicrobial effect lacks persistence and inferior heat resistance The application is limited in point. In addition, dyes extracted from natural materials have the advantage of imparting antimicrobial properties from the dyeing stage, but it is necessary to use a mordanting method using another heavy metal for improving the fastness, which is a disadvantage of natural dyes, There are disadvantages.
In this respect, silver is less toxic to humans than general organic antimicrobial agents and has been known to have excellent antimicrobial, antiseptic, antifungal, deodorant, far-infrared radiation and antistatic properties.
Recently, nanoparticles of nano-sized silver nanoparticles are expected to exhibit more excellent properties than those of bulk silver. Numerous studies have been conducted on nanotechnology for producing silver nanoparticles in powder or solution form. Particles show 99% or more germicidal power within a few seconds for any kind of bacteria, showing much improved antibacterial, antiseptic and antifungal effect than bulk silver.
However, it is an important issue to effectively incorporate silver nanoparticles into the fibers and to sustain them continuously for a long period of time. Further, although the silver nanoparticle-coated fiber has antistatic function, it is necessary to impart a more excellent antistatic function to the fiber.
For this purpose, conventionally, there is a method of spinning a mixture containing a metal component in a fiber manufacturing process. However, this method has a high manufacturing cost and difficulty in manufacturing due to a difficulty in manufacturing machines due to the metal components contained in fabric processing. In addition, there is a method of spraying an antistatic liquid on a fabric, but this method has a disadvantage in that it can not maintain a long-term effect because it is close to one-time.
Accordingly, an object of the present invention is to provide a method for weaving an antimicrobial fabric using silver nano, which reduces the cost of weaving and provides antimicrobial properties equivalent to that of a fabric woven with conventional nano-sized yarn.
In order to accomplish the object of the present invention, in an embodiment of the present invention, a first synthetic resin yarn and a first silver nano yarn having a smaller thickness than the first synthetic resin yarn are processed to produce a first yarn of a predetermined thickness A second yarn processing step of binding a second silver nano yarn having a thickness smaller than that of the second synthetic resin yarn and a second synthetic resin yarn to produce a second yarn; The present invention provides a method of weaving an antimicrobial fabric using silver nano including a fabric weaving step of weaving an antimicrobial fabric by dividing into a warp and a weft.
According to the present invention, it is possible to provide antibacterial performance required by clothes such as 100% antimicrobial fabric woven using nano yarn, and it is possible to provide the antibacterial fabric with a cost of 20% or more compared to the antibacterial fabric woven using 100% nano yarn .
In addition, since the present invention uses a yarn containing silver nano produced by the yarn improvement method, the woven fabric is relieved of durability deterioration due to washing and is absolutely safe for the human body while maintaining the antibacterial effect continuously.
In addition, the fabric woven through the weaving method of the present invention alleviates the deterioration of the antibacterial function even after the use period has elapsed.
In addition, the fabric woven through the weaving method of the present invention can replace the surface material of the office partition and the interior wall paper, thereby inhibiting the propagation of bacteria in the room.
1 is a flow chart for explaining a weaving method of an antibacterial fabric according to the present invention.
FIGS. 2 to 4 are test reports of an antibacterial fabric woven through the weaving method of the antibacterial fabric according to the present invention.
Hereinafter, a method for weaving an antimicrobial fabric using silver nano according to preferred embodiments of the present invention (hereinafter referred to as " method for weaving an antimicrobial fabric ") will be described in detail with reference to the accompanying drawings.
1 is a flow chart for explaining a weaving method of an antibacterial fabric according to the present invention.
1, the method for weaving an antimicrobial fabric according to the present invention includes a first yarn processing step S100 (see FIG. 1) for producing a first yarn of a predetermined thickness by processing a first synthetic resin yarn and a first silver nano- A second yarn processing step (S200) for binding the second synthetic resin yarn and the second silver yarn to produce a second yarn, and a second yarn processing step (S200) for dividing the first yarn and the second yarn into warp yarns and weft yarns, And weaving the fabric.
Hereinafter, each component will be described in more detail with reference to the drawings.
First, a method of weaving an antibacterial fabric according to the present invention includes a first yarn processing step (S100).
The first yarn processing step S100 is a step of producing a first yarn, which is an air textured yarn, by processing a first synthetic resin yarn and second silver nano yarns using silver nanoparticles, An air textured process may be used. Here, the air-texturing process refers to a processing method in which a yarn is weaved such that the surface of the fiber is continuously beaten by the pressure of air to make it like a peach skin to make the surface of the fabric or knitted fabric smooth and soft.
In this first yarn, a silver nano yarn having a thickness smaller than that of the first synthetic resin yarn is used as the first silver nano yarn so that the first silver nano yarn uses a smaller mass than the first synthetic resin yarn.
The first synthetic resin yarn may be formed to have a thickness of about 70% of the first yarn thickness based on the first yarn.
More specifically, synthetic resin yarns having a denier of 650 to 750 denier may be used as the first synthetic resin yarn, and silver nano yarns having a denier of 250 to 350 denier may be used as the first silver nano yarn. This is because not only the productivity of the silver nano-yarn yarn of less than 250 denier is lowered, but also the case that the first yarn contains less than 25% by weight of the nano-yarn based on the first yarn 100% May occur.
For example, in the first yarn processing step (S100), a synthetic resin yarn having a thickness of 700 denier and a silver denier yarn having a denier thickness of 300 are arranged in the nozzle, and then the synthetic resin yarn and the silver nano yarn having passed through the nozzle are entangled 1 yarn is produced by passing the synthetic resin yarn and the silver nano yarn through the nozzle by the air pressure of the compressed air to the nozzle. If necessary, the thickness and number of the first synthetic resin yarn and the first silver nano yarn may be adjusted so that the first yarn produced through the nozzle has a thickness of about 1000 denier.
As the first synthetic resin raw material, a yarn made of polypropylene, nylon, rayon, or a mixture thereof may be used.
Preferably, the first silver nano-source yarn is a silver nano-yarn produced through a yarn improvement method in which 30 to 40% by weight of silver nanoparticles are contained in a yarn.
If the amount of the silver nanoparticles contained in the silver nano yarn is less than 30% by weight, the antibacterial ability of the yarn may be reduced and a certain level of antimicrobial activity may not be expressed on the fabric. If the amount of the silver nanoparticles exceeds 40% by weight, the antimicrobial activity required for the antimicrobial fabric is not greatly changed. However, the manufacturing cost may increase and the cost competitiveness of the antimicrobial fabric may be deteriorated.
Next, the weaving method of the antibacterial fabric according to the present invention includes a second yarn processing step (S200).
The second yarn processing step S200 is a step of producing a second yarn as a binding yarn by binding a second synthetic resin yarn and a second silver nano yarn having a smaller thickness than the second yarn.
The second synthetic resin yarn may be formed to have a thickness of about 70% of the second yarn thickness based on the second yarn. More specifically, when the second yarn is formed to have a thickness of about 1000 denier, the synthetic resin yarn may be formed to have a denier of 650 to 750 denier, preferably 700 denier.
As the second synthetic resin raw material, a yarn made of polypropylene, nylon, rayon, or a mixture thereof may be used.
The second synthetic resin yarn used in the second yarn reduces the cost of weaving the antibacterial fabric and increases the durability of the antibacterial fabric. The second synthetic resin yarn is combined with the first yarn after being bonded to the second silver nano yarn, Provides the fixing force to the silver nanoparticles of the antibacterial fabric so that the nanoparticles do not separate from the antibacterial fabric during washing or use.
These silver nanoparticles, when introduced into the body's bronchial tubes, can increase the concentration of calcium in the cells and cause blood clotting, which can increase the risk of heart attack or stroke, so silver nanoparticles contained in the antibacterial fabric It is important not to be separated.
The second silver nano-source yarn is formed of silver nano-sized yarn having a thickness smaller than that of the second synthetic resin yarn, and the second yarn has a thickness that assists the thickness of the synthetic resin yarn so that the second yarn may have the same or similar thickness as the first yarn.
For example, when the second synthetic resin yarn is formed to have a thickness of 650 to 750 denier, the second silver nano-source yarn may be formed to have a denier of 250 to 350 denier, preferably 300 denier.
For this purpose, it is preferable that the number of the second synthetic resin yarn used for producing the second yarn and the number of the second silver nano yarn are used in a ratio of 1: 1.
On the other hand, it is preferable that the second silver nano yarn is silver nano yarn produced through a yarn improvement method in which 30 to 40% by weight of silver nanoparticles are contained in the yarn.
At this time, if the silver nanoparticles contained in the second silver nanoparticles are less than 30% by weight, the antimicrobial activity of the yarn may be reduced and a certain level of antimicrobial activity may not be developed on the fabric. If the amount of the silver nanoparticles exceeds 40% by weight, the antimicrobial activity required for the antimicrobial fabric is not greatly changed. However, the manufacturing cost may increase and the cost competitiveness of the antimicrobial fabric may be deteriorated.
Next, the weaving method of the antibacterial fabric according to the present invention includes fabric weaving (S300).
In the fabric weaving step S300, the first yarn produced through the first yarn processing step S100 and the second yarn produced through the second yarn processing step S200 are divided into warp yarns and weft yarns, respectively, It is a step of weaving.
More specifically, when the first yarn is used as a warp in the fabric weaving step (S300), the second yarn is used as a weft. When the first yarn is used as a weft, the second yarn is used as a warp.
As described above, since the fabric woven by the first yarn and the second yarn is composed of the air texture yarn at one of the warp yarns and the weft yarn and the binding yarn at the other one of the warp yarns and the weft yarns, it provides a soft touch feeling when used as the surface material of the office partition And can provide a firm resilience when used as an indoor interior wallpaper.
Hereinafter, specific examples and experimental examples of the present invention will be described in more detail. It should be understood, however, that the embodiments and examples are for the purpose of promoting understanding of the specific examples of the invention described above, and the scope of rights and the like should not be construed thereby.
[Example]
1. A 700 denier polypropylene yarn and 300 denier silver nano yarn were placed in a nozzle, compressed air was supplied to the nozzle, and each yarn was passed through a nozzle to produce a first yarn of 1000 denier thickness. At this time, a silver nano yarn containing 30% by weight of silver nanoparticles in the yarn was used as the silver nano yarn.
2. A second yarn was produced by binding 700 denier polypropylene yarn and 300 denier silver nano yarn. At this time, a silver nano yarn containing 30% by weight of silver nanoparticles in the yarn was used for the second yarn.
3. The first yarn was tilted and the second yarn was divided into weft yarns to weave the fabric. At this time, the fabric was referred to as
[Comparative Example]
A 300-denier polypropylene yarn was used in place of the 300-denier silver nano yarn used in the first yarn.
[Experimental Example 1]
The strains of Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) were provided on the fabrics fabricated according to the above examples and commercially purchased cotton fabrics, and the antibacterial activity test (KS K 0693 application) As shown in the test report shown in FIG. At this time, the initial concentration of Staphylococcus aureus (ATCC 6538) was 1.3 x 10 5 CFU / ml, and the initial concentration of Klebsiella pneumoniae (ATCC 4352) was 1.2 x 10 5 CFU / ml.
According to the above experimental results, the bacteriostatic reduction rate of Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) detected in the fabric of the Example after incubation for 18 hours was 99.9%. Staphylococcus aureus was found to be 6.6 × 10 6 CFU / ㎖ in the cotton fabric after 18 hours incubation and 6.5 × 10 6 CFU / ㎖ in the papillary bacterium (Klebsiella pneumoniae).
In other words, unlike the case where the number of viable cells was about 50 times or more than that of the general cotton fabric, less than 10 viable cells were observed after 18 hours in the fabric prepared by the method of the present invention. The antimicrobial activity was confirmed.
[Experimental Example 2]
The strains of Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) were provided on the fabrics prepared according to the above comparative examples and commercially available cotton fabrics, and the antibacterial activity test (KS K 0693 application) As shown in the test report shown in FIG. At this time, the initial concentration of Staphylococcus aureus (ATCC 6538) was 2.4 x 10 4 CFU / ml, and the initial concentration of Klebsiella pneumoniae (ATCC 4352) was 2.5 x 10 4 CFU / ml.
According to the above experimental results, Staphylococcus aureus and Klebsiella pneumoniae were detected at 2.1 × 10 6 CFU / ㎖ and 1.9 × 10 7 CFU / ㎖, respectively. Staphylococcus aureus was 2.0 × 10 6 CFU / ㎖, and Klebsiella pneumoniae was 2.0 × 10 7 CFU / ㎖ after 18 hours incubation.
In other words, since the increased number of viable cells was observed in the fabric of the comparative example as in the cotton fabric, it was confirmed that the antibacterial activity was insignificant.
As a result, it was confirmed that the fabric composed of the first yarn made of the synthetic resin yarn and the nano-sized yarn exhibited excellent antibacterial power compared to the fabric made of the first yarn made only of the synthetic resin yarn.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
