Description

Technology Field

[0001] The present invention relates to a method for manufacturing a fabric having antibacterial and deodorizing functions using special yarns, and more specifically, to a method for manufacturing a fabric having antibacterial and deodorizing functions using improved special yarns by combining special yarns such as copper yarn and charcoal yarn to significantly enhance antibacterial properties, deodorizing and odor removal, as well as antistatic properties and electromagnetic shielding properties, thereby improving the wearing comfort of the garment and ensuring a more pleasant user experience by increasing the ability to remove odors such as sweat smell. Background Technology

[0002] Generally, the primary purpose of clothing is to protect the body, but in addition to this, it is also a means to enhance aesthetics and present oneself as beautiful and stylish.

[0003] These garments exist in various forms, ranging from socks and underwear to outerwear, and there are countless types of functional clothing.

[0004] Also, cotton, polyester, acrylic, linen, chiffon, rayon, nylon, suede, wool, silk, hemp, polyurethane, and polypropylene are mainly used as fabrics to make such clothing.

[0005] However, among these fabrics, synthetic fibers other than natural fibers often cause discomfort due to static electricity, and particularly in the case of underwear, they have the disadvantage of absorbing sweat and generating bad odors because they come into direct contact with the skin.

[0006] To address this, many clothing items with enhanced breathability are on the market, but there are not many examples that effectively improve antibacterial, electromagnetic shielding, and antistatic functions along with deodorizing capabilities.

[0007] Accordingly, there is a continuous demand for the development of clothing fabric manufacturing methods that can implement these special functions while reducing costs. Prior art literature

Brief explanation of the drawing

[0012] FIGS. 1 to 3 are exemplary sample photographs of clothing made using a fabric manufactured by the method for manufacturing a fabric having antibacterial and deodorizing functions using special yarn according to the present invention. Specific details for implementing the invention

[0013] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0014] Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0015] The method for manufacturing a fabric having antibacterial and deodorizing functions using special yarn according to the present invention provides a method for manufacturing a fabric that can be applied to everything belonging to the concept of clothing, including not only ordinary clothing ranging from underwear to outerwear, but also socks.

[0016] Such fabrics can be exemplified by those shown in FIGS. 1 to 3. In particular, as indicated by the circle in the illustrated sample photograph, the fabric according to the present invention is also characterized by having a functional member attached to it to perform a specific function. In this case, it is preferable that the functional member be attached by sewing, and the functional member will be described later.

[0017] A method for manufacturing a fabric having antibacterial and deodorizing functions using special yarn according to the present invention comprises: a first step of making copper fiber by coating polyester with copper; a second step of making charcoal fiber by coating polyester with charcoal; and a third step of making a fabric by weaving or knitting the copper fiber and charcoal fiber.

[0018] At this time, the copper yarn prepared in the first step is a special yarn with natural antibacterial properties, and is one of the yarns that was particularly useful during the COVID-19 pandemic.

[0019] These copper yarns are made by coating polyester yarn with copper.

[0020] In particular, it has been reported in the academic community that copper fibers, when made into fibers, have an antibacterial effect of 90 to 99.99% against Staphylococcus aureus or Streptococcus pneumoniae, as well as a deodorizing function.

[0021] Moreover, because it has excellent electrical conductivity and conductivity, it also has an electromagnetic shielding function.

[0022] Meanwhile, the charcoal fiber prepared in the second stage has excellent antibacterial, deodorizing, deodorizing, breathability, and moisture absorption properties. Graphene fiber may also be used.

[0023] The above charcoal yarn is also made by coating charcoal onto polyester yarn.

[0024] If graphene yarn is used instead of charcoal yarn, graphene polyester chips or graphene viscose rayon raw materials are first prepared in a bonded state through polymerization with graphene, and then spun to make graphene long fibers. These graphene yarns are widely used in medical and hygiene products, various sportswear, etc., as they have excellent antibacterial, anti-odor, and antistatic properties due to the unique characteristics of graphene.

[0025] When making fabric using such verbs and charcoal yarns, the burden of making the entire fabric is heavy because the verbs are expensive.

[0026] Accordingly, the present invention is characterized in that copper yarn is used partially, including in the area requiring antibacterial action or the Y-zone, and charcoal yarn is used throughout the fabric.

[0027] In other words, expensive copper yarn is inserted only where necessary during weaving or knitting, while charcoal yarn is used throughout when making fabrics or clothing. This results in excellent deodorizing, odor removal, and anti-odor functions.

[0028] On the other hand, the functional member may be any one of graphene, cloisonné, maifan stone, or volcanic scoria.

[0029] In addition, these functional members can be attached in various shapes, preferably in the shape of a button.

[0030] These functional components can further enhance functions such as antibacterial, deodorizing, and odor removal, in addition to the far-infrared radiation emission function.

[0031] Additionally, the above functional member can be used in a coated state after being immersed in a functional immersion solution.

[0032] At this time, the functional immersion solution may be composed by mixing 10 parts by weight of wood ash nanopowder, 15 parts by weight of solubilizer, 5 parts by weight of acetic acid, and 7.5 parts by weight of sodium hypochlorite with respect to 100 parts by weight of PBAT (Poly-Butylene Adipate Terephthalate).

[0033] In this case, PBAT (Poly-Butylene Adipate Terephthalate) is a biodegradable resin made by blending BDO (Butanediol), Ada (Adipic Acid), and TPA (Terephthalic Acid), and serves as a base resin to enhance flexibility, processability, and adhesion to substrates.

[0034] Furthermore, Mogeoseok nanopowder is a material composed of a hollow structure filled with granules, powder, or liquid, exhibiting excellent deodorizing and hygroscopic properties, as well as superior characteristics for the leaching of trace elements useful to the human body and far-infrared radiation emission.

[0035] In addition, while the solubilizer is typically used as an emulsifier, in this invention, it reacts with acetic acid to decompose organic matter and enhances deodorizing and odor-removing properties.

[0036] In addition, acetic acid decomposes organic matter and reacts with solubilizers to enhance the deodorizing function.

[0037] Furthermore, sodium hypochlorite is a crystalline powder with high oxidizing power, making it excellent for sterilization and deodorization. It also has deodorizing properties, making it particularly effective for removing sweat odor.

[0038] In addition, to the above functional immersion solution, 15 parts by weight of Acetum, 5 parts by weight of Sepiolite, 5 parts by weight of Celite, 5 parts by weight of tetraethyl orthosilicate, 5 parts by weight of benzoic acid vinyl ester, and 5 parts by weight of diphenylphosphoryl azide may be further added to 100 parts by weight of PBAT (Poly-Butylene Adipate Terephthalate).

[0039] In this case, Acetum enhances antistatic properties as a plant-based antistatic agent.

[0040] In addition, Sepiolite is a round tubular variant called Meerschaum, which has the characteristic of deodorizing and eliminating odors by promoting the separation of odor components through the adsorption of organic matter.

[0041] At this time, Celite is a substance corresponding to CAS number 61790-53-2, and in addition to its deodorizing and sterilizing effects, it has the characteristic of having excellent heavy metal neutralization ability.

[0042] In addition, tetraethyl orthosilicate contributes to maintaining breathability while ensuring excellent water-repellent properties by significantly increasing the contact angle.

[0043] In addition, benzoic acid vinyl ester is a substance corresponding to CAS number 769-78-8 that protects the surface and inhibits contamination by absorbing ultraviolet rays through photodegradation action against ultraviolet rays.

[0044] In addition, diphenylphosphoryl azide is a substance corresponding to CAS number 26386-88-9, which increases compatibility with resin and strengthens water pressure resistance.

[0045] For fabric samples prepared according to the present invention, to test antibacterial activity, 0.1 ml of fungal strains were dropped at intervals on each of five fabric samples, and the antibacterial activity was checked for 5, 10, and 15 days.

[0046] At this time, the test method followed ASTMG-21, and activity was confirmed by the presence or absence of growth of the cultured strains; three types of fungal strains were used for testing: Fusarium, Trichoderma, and Penicillium. As a result of observation, no growth of the strains was observed. Through this, it was confirmed that the strains possess antimicrobial activity.

[0047] In addition, after being left in an odorous environment for 20 hours, the deodorizing and odor removal functions were verified, and the odor disappeared in 3 hours.

[0048] Through this, it was confirmed that it has deodorizing and odor removal functions.

[0049] In particular, the inventor has been continuously conducting research from 2021 to the present to complete the present invention, and basic antibacterial and deodorizing tests were completed by applying them to socks in 2021. However, the patent application was delayed somewhat as continuous experiments were conducted to expand the scope to various clothing fabrics, including shapewear, there is no doubt that the patent application was delayed.

[0050] Therefore, the test report attached below is data that is under development in 2021.
