Generally, in the case of functional fibers containing natural substances, fibers made of soy protein components, fibers containing chitosan extracted from crab shells, fibers made of bamboo extracts, far infrared and anion emitting fibers made from bio ceramics, and silver components There are fibers, and also functional fibers were formed by dyeing or printing fibers or coating the surface of woven fibers by adding natural materials such as elvan, jade, germanium, loess, and charcoal. In addition, the fragrance fibers were formed by processing the particulate granules with the fragrance in the form of particulates on the surface of the fabric, and the fragrances were blown off by the friction.

However, these functional fibers have a problem that functional materials are hardly adhered to the fibers or yarns or are difficult to be absorbed, thereby reducing their durability, and increasing the number of washings, the original functionality does not persist, and also exhibits sufficient antibacterial and antifungal properties. In order to produce a problem, there is a problem in that an excessive amount of additive is used, and thus the mechanical properties of the final fiber are poor, or the yarn is cut off in the spinning process, which is a process of manufacturing the fiber.

Therefore, the present invention has been devised in view of the above-mentioned disadvantages and problems that occur, by using a mineral powder in addition to the ultra-fine size or finely powdered sulfur of the antimicrobial power and antifungal power to further increase the antibacterial and antifungal effect. It provides a novel fiber and a fabric using the same, characterized in that the height.

In other words, an object of the present invention, while having antibacterial and antifungal activity with the sulfur component, elite, elvan, agate, jade, jasper, amethyst, germanium stone, selenium having antibacterial, antifungal and far-infrared-generating effects By adopting a component having any one or more minerals of ocher, charcoal, to provide a fiber having a far infrared ray generating effect and a fabric using the same while further increasing the antibacterial and antifungal effect.

The present invention is selected from the sulfur component of the nano-size or fine powder and antibacterial, antifungal power and far-infrared ray-generating effect, elite, bar stone, agate stone, jade, jasper, amethyst, germanium stone, selenium, ocher, charcoal Provided is an antimicrobial antifungal masterbatch comprising at least one component and a synthetic resin component.

In addition, the present invention, unlike the existing antibacterial agent, inhibits the growth of fungi, bacteria, fungi and viruses that cause odors by sterilization and sterilization to maintain cleanliness and effectively remove the smell of athlete's foot, eczema, etc. It provides a containing yarn and a fabric using the same.

As a result of many efforts to solve the above problems, the present invention has been completed by knowing the antimicrobial and antifungal mycelium and antimicrobial and antifungal article and its manufacturing method by adopting the following configuration.

That is, the antimicrobial, antimycotic or antimicrobial fragrance and antifungal scent of the present invention is sulfur or illite, ganban stone, agate stone, jade, jasper, amethyst, germanium, selenium, ocher with antibacterial and antifungal power in the basic yarn itself. By incorporating minerals such as charcoal and fragrance (fragrance component), a new functional fiber is produced without a reduction in mechanical properties or effects of use, thereby completing the present invention.

In addition, the present invention is to prepare each component in a masterbatch to re-mix them in order to solve the yarn cutting due to the dispersion of the powder additive or the quality non-uniformity and the agglomeration of the additive in the manufacturing process of the conventional functional fiber By adopting the method, excellent antimicrobial, antimycotic or antimicrobial and antifungal flavours were produced.

In another aspect, the present invention is to produce a functional batch having excellent mechanical strength by producing a master batch comprising a nano-size micro-fine or sulfur particles having a size of less than 3 ㎛ or liquid or fragrance particles having a size of 3 ㎛ Could.

Hereinafter, the configuration of the present invention will be described.

The first embodiment of the present invention is a nano-sized ultra fine nano or fine sulfur powder of less than 3㎛ 10-25%, synthetic resin 64-84.7% by weight, polymer dispersant 5-10% by weight and antioxidant 0.3-1% by weight % Is mixed and melt-extruded at a temperature of 120 ° C. to 280 ° C., followed by cooling to 4 ° C. to 95 ° C. and cutting to produce an antibacterial and antifungal master batch. In the present invention, when the antimicrobial antifungal master batch is prepared, the amount used may be controlled to a certain extent as necessary, but preferably, the chemical stability or antimicrobial antifungal properties and odors of the final product may be exceeded. It is not good to be not satisfied enough.

The second aspect of the present invention is 5 to 7% by weight of the fragrance masterbatch mixed with 10 to 25% by weight of fragrance powder, 64 to 84.7% by weight of synthetic resin, 5 to 10% by weight of polymer dispersant and 0.3 to 1% by weight of antioxidant. It is to provide a color masterbatch containing a colorant pigment. The particle size of the fragrance which is the fragrance powder to be used in the present invention is nano size and ultrafine size of about 3㎛ or less, the composition ratio of each component of the fragrance masterbatch can be appropriately adjusted as necessary, but preferably When used in the above range may have a sufficient aroma, there is no cutting during spinning and the mechanical properties of the final product is satisfactory.

The third aspect of the present invention is to prepare a first antimicrobial antifungal composition consisting of 10 to 20% by weight of the antibacterial and antifungal master batch and 90 to 80% by weight of the synthetic resin component, spinning, cooling and stretching the antimicrobial and antifungal mycelia and antibacterial fragrance · To produce antifungal articles. The composition ratio of the master batch and the synthetic resin can be appropriately adjusted as necessary, but the use in the above range is good in terms of work stability due to no mechanical properties or cutting during spinning, and the range is suitably adjusted by those skilled in the art as needed. It is possible.

4th aspect of this invention contains 5-7 weight% of fragrance masterbatch, 2-5 weight% of color masterbatches containing a coloring agent pigment, or an antistatic agent in 10-20 weight% of antimicrobial and antifungal masterbatch prepared above. To prepare a second antimicrobial antifungal composition comprising any one or more components selected from 2 to 5% by weight of the antistatic agent, and the remaining components consisting of synthetic resin components, spinning, cooling and stretching them to antibacterial and antimycotic and To produce antibacterial and antifungal fragrance articles. When the composition of the second antibacterial antifungal composition is out of the above range, it is not good because it cannot secure sufficient mechanical strength and production stability of spinning during a sufficient degree.

According to the above embodiments of the present invention, maintaining a hygienic environment without bacteria, inhibiting the growth of fungi, bacteria, fungi and viruses that cause odors, sterilization and sterilization to maintain cleanliness, athlete's foot, eczema smell, etc. It can be eliminated and also embedded in sulfur fiber which has the property of bonding (PbS, AgS) when it comes into contact with lead metal (Pb) or mercury (Ag), which is harmful to the human body. It is expected to have the ability to do so. Moreover, sulfur interacts with organic substances to form pentathiic acid (HO-SO ₂ -S ₃ -SO ₂ -OH), which dissolves the dead skin cells and acts as an insecticide and sterilizing agent, providing benefits to consumers. I expect to be able to.

In the process of mixing the antimicrobial and antifungal masterbatch according to the present invention with synthetic resins, the fragrance masterbatch, the color masterbatch and the antistatic agent batch, etc. are added and mixed to form a basic yarn through one of wet spinning, dry spinning or melt spinning. By forming (yarn), it maintains the physical properties of synthetic yarn itself, and has excellent stability as an antibacterial or antifungal agent, long-term antibacterial and antifungal activity, and excellent stability as a fragrance yarn (scented yarn). Its activity is maintained for a long time and its washing resistance is excellent, so that antibacterial, antifungal, antibacterial and antifungal articles and antifungal articles are produced.

The present invention is characterized in that the sulfur component is used as a main component to give antibacterial antifungal properties, and further uses a mineral having antifungal antifungal performance, and the use of each of the above components as the sulfur powder itself. It is also characterized by the production of fibers by mixing the master batch and synthetic resin after the production in a master batch. By this characteristic configuration, the present invention enables more uniform dispersion, and improves the adhesion between the antibacterial antifungal additives and the synthetic resin, and thus has the effect of maintaining the fungal antifungal properties according to continuous use. In addition, after manufacturing in a master batch as in the present invention, when manufacturing a composition by mixing the synthetic resin and the master batch and spinning the yarn to minimize the change in physical properties during processing, to prepare a basic yarn of uniform properties It can provide benefits to producers such as economical antibacterial and antifungal processing, extensive antibacterial and antifungal processing capability, reduced production cost, small quantity production, minimization of yield, and improved production yield, and ease of product design.

The sulfur content used in the present invention is preferably used in the range of 1% by weight or more and 6% by weight or less with respect to the composition for producing the yarn. More preferably, it is more preferable in the range of 1.5 to 4.5 weight%. If less than 1% by weight does not exhibit sufficient antibacterial antifungal properties, when using more than 6% by weight may cause an odor due to the excess of sulfur, and may be poor long-term usability due to oxidation by sulfur.

Example 6

Sulfur powder 3 (normal sulfur content, 0.45 wt%), 10 (1.5 wt%), 15 (2.25 wt%), 25 (3.75 wt%), 30 (4.5 wt%) And polyethylene terephthalate resin having an ultimate viscosity of 0.64 as measured by 40 wt% (5.25 wt%) and 7 wt% polyethylene glycol dispersant having a number average molecular weight of 2300 and 0.5 wt% Iganox 1035 and 0-chlorophenol solution at 25 ° C. 15% by weight of antibacterial and antifungal master batch pellets prepared by mixing the mixture to 100% of the total content, melt extruding at 272 ° C using a twin screw extruder, and then cooling the mixture to a temperature of 40 ° C. 85 wt% of polyethylene terephthalate pellets having an intrinsic viscosity of 0.64 measured by chlorophenol solution were melt spun at 285 ° C., cooled and stretched to prepare a stretched yarn of 50d / 36f. The antimicrobial effect of the drawn yarn and the persistence of the antimicrobial effect of the long-term washing was measured. The analysis results are shown in Table 2. In addition, in order to evaluate the persistence of the antimicrobial and antifungal, after washing up to 50 times to evaluate the antimicrobial antifungal properties, but no significant change was found that the antimicrobial and antifungal composition according to the present invention has a very good long-term effect persistence. When the sulfur content is less than 1% by weight, the initial antimicrobial and antifungal properties were maintained as it is, the composition of the present invention was found to have a very good antibacterial and antifungal lasting effect.

The present invention by the above configuration, by adding the base from the basic step of forming a base yarn (yarn) containing sulfur and antibacterial and antibacterial and antifungal and minerals and fragrance components, that is, fragrances By forming yarns, the physical properties of the fibers themselves are maintained, and sulfur components with antibacterial and antifungal powers or mineral components and fragrances (fragrances) with antibacterial and antifungal powers can last for a long time and are durable even when washing. It has the effect of being maintained.

In addition, since the sulfur component having antibacterial and antifungal activity or various mineral components having antibacterial and antifungal power are contained in the basic yarn (yarn) in the form of particles, it is not necessary to undergo a separate antibacterial and antifungal treatment process. There is an effect that can reduce the number of processes.

In addition, the fragrance master batch, which is a fragrance with fragrance ingredients, is contained in the basic yarn (yarn) in the form of particles so that the fragrance is eliminated, so that it is not necessary to go through a separate fragrance treatment process. It can reduce the effect.
