Description
本発明は、衣類用原糸、特にスポーツ衣類用原糸として使用する場合、汗をよく吸収するだけでなく、吸収した汗を容易に乾燥させる性質（以下、“吸汗速乾性”という）と、繊維の変色及び脱色を誘発する菌又は人体に有害な菌が浸透及び増殖されることを抑制する機能（以下、“抗菌性”という）に優れたマルチフィラメント（原糸）に関するものである。 The present invention, when used as a garment yarn, especially a sports garment yarn, not only absorbs sweat well, but also easily dries the absorbed sweat (hereinafter referred to as “sweat-absorbing quick-drying”), The present invention relates to a multifilament (raw yarn) excellent in a function (hereinafter referred to as “antibacterial”) that suppresses the invasion and proliferation of bacteria that induce discoloration and decoloration of fibers or bacteria harmful to the human body.
近年、生活水準が向上するにつれて、様々な機能性を有する衣類に対する需要が拡大されている。即ち、単純な物理的・化学的な耐久性だけでなく、吸汗速乾性と抗菌性を有している衣類が要求されている。従来、吸水性の良好な綿糸や綿／ポリエステルの混紡糸が衣類用原糸として主に使われてきたが、多量の汗が出ると、前記原糸が汗を多量含有するようになるので、湿っぽくて冷たくて感じられるだけでなく、衣類が体に絡まってべたつくようになるという問題と、細菌による繊維の変色又は脱色、長時間着用による汗臭い或いは悪臭の発生の問題、即ち抗菌性が落ちるという問題とがあった。 In recent years, as the standard of living has improved, the demand for clothing having various functionalities has been expanded. That is, there is a demand for clothing that has not only simple physical and chemical durability but also sweat-absorbing quick-drying and antibacterial properties. Conventionally, cotton yarns with good water absorption and cotton / polyester blended yarns have been mainly used as garment yarns. However, when a large amount of sweat comes out, the yarn contains a lot of sweat. Not only does it feel moist and cold, but also causes problems such as clothing becoming tangled and sticking to the body, discoloration or discoloration of fibers due to bacteria, generation of sweaty odor or bad odor due to prolonged wearing, that is, antibacterial properties are reduced There was a problem.
一方、吸汗速乾性を改善するための従来技術として、米国特許第４，４７０，４０７号では、原糸の水分拡散性を改善するために、図４のように、貝殻模様の断面を持つポリエステルの異形断面糸を開示しており、大韓民国公開特許第１９９９−７７３６号では、図５のように、３個以上５個以下の球状突起部が等間隔で形成されている異型断面糸を開示している。前記従来の異形断面糸等は、汗を排出する通路の役割をする突起が２個以上５個以下しか形成されていないため、吸汗速乾性及び快適性が不十分であるという問題点があり、抗菌性を十分ではないという問題点があった。 On the other hand, US Pat. No. 4,470,407 discloses a conventional technique for improving sweat-absorbing and quick-drying properties, in order to improve moisture diffusibility of the raw yarn, as shown in FIG. Korean Patent No. 1999-7736 discloses a modified cross-section yarn in which three or more and five or less spherical protrusions are formed at equal intervals, as shown in FIG. ing. The conventional modified cross-section yarn and the like have a problem that sweat-absorbing quick-drying and comfort are insufficient because only two or more and five or less protrusions that function as a passage for discharging sweat are formed. There was a problem that the antibacterial property was not sufficient.
また、大韓民国公開特許第２００２−７１５２２号では、図２のように、６個の球状突起等が対称的に形成されている異形断面糸を開示している。しかしながら、このような異形断面糸の場合、その吸汗速乾性は優れるが、抗菌性が十分でないという問題があった。 In addition, Korean Patent Laid-Open No. 2002-71522 discloses a modified cross-sectional yarn in which six spherical protrusions are formed symmetrically as shown in FIG. However, in the case of such a modified cross-section yarn, the sweat-absorbing quick drying property is excellent, but there is a problem that the antibacterial property is not sufficient.
繊維に抗菌性を付与しようとする従来技術としては、抗菌剤溶液内に織物を浸漬して抗菌性を付与する方法が広く使われているが、この場合、１０回以上洗濯すると、その抗菌機能を失うという問題、即ち、耐洗濯性が低いという問題があった。 As a conventional technique for imparting antibacterial properties to fibers, a method of imparting antibacterial properties by immersing a fabric in an antibacterial agent solution is widely used. There is a problem that the washing resistance is low.
繊維に抗菌性を付与する他の従来技術としては、繊維素材である高分子樹脂に抗菌活性物質を含む共重合成分を共重合させる方法と、高分子樹脂の内部に微細抗菌剤をブレンディング（ｂｌｅｎｄｉｎｇ）する方法等も使われている。 Other conventional techniques for imparting antibacterial properties to fibers include a method of copolymerizing a polymer resin, which is a fiber material, with a copolymer component containing an antibacterial active substance, and blending a fine antibacterial agent inside the polymer resin. ) Method is also used.
抗菌剤としては、キトサン類等の天然系抗菌剤、銀系又は光触媒機能を有する無機系抗菌剤が使われているが、その中でも、高温の紡糸工程でよく耐えられる無機系抗菌剤が広く使われる。 Antibacterial agents include natural antibacterial agents such as chitosans, silver or inorganic antibacterial agents that have a photocatalytic function. Among them, inorganic antibacterial agents that can withstand high temperature spinning processes are widely used. Is called.
上述した方法等によっても、繊維に抗菌性を付与することができるが、その耐洗濯性は悪く、その吸汗速乾性を同時に付与することができないという問題点があった。 Although the antibacterial property can be imparted to the fiber by the above-described method, there is a problem in that the washing resistance is poor and the sweat-absorbing quick-drying property cannot be imparted at the same time.
本発明の目的は、このような従来の問題点等を解決するために、吸汗速乾性と抗菌性が同時に優れた原糸（マルチフィラメント）を提供することである。 An object of the present invention is to provide a yarn (multifilament) having excellent sweat-absorbing quick-drying properties and antibacterial properties at the same time in order to solve such conventional problems.
本発明は、原糸（マルチフィラメント）を構成するモノフィラメント等の断面を、図２のように、球状突起６個が対称的に形成されて異形となるように形成することにより、吸汗速乾性を向上させると共に、リン酸ジルコニウムに銀（Ａｇ）が担持された銀系無機抗菌剤（直径：０．１μｍ以上１．０μｍ以下）を原糸（マルチフィラメント）内に分散・含有させることにより、作業性を低下させずにマルチフィラメントに抗菌性を付与しようとする。 In the present invention, the cross-section of the monofilament or the like constituting the raw yarn (multifilament) is formed so that six spherical protrusions are formed symmetrically as shown in FIG. Work by dispersing and containing a silver-based inorganic antibacterial agent (diameter: 0.1 μm or more and 1.0 μm or less) in which silver (Ag) is supported on zirconium phosphate in the raw yarn (multifilament). Attempts to impart antibacterial properties to multifilaments without reducing the properties.
上記のような課題を達成するために、本発明によるマルチフィラメントは、（Ｉ）熱可塑性樹脂の複数のモノフィラメントから構成され、（ＩＩ）前記モノフィラメントは、球状突起６個がモノフィラメントの断面の長軸長さ（Ｌ１）を基準として上部面に２個、下部面に２個、左側面に１個、右側面に１個ずつ対称的に形成された異形断面を有し、（ＩＩＩ）平均粒径が０．１μｍ以上１．０μｍ以下で、無機担体であるリン酸ジルコニウムに銀（Ａｇ）が担持された銀系無機抗菌剤が、全体原糸重量に対して０．３質量％以上２．０質量％以下含有されていることを特徴とする。

まず、本発明は、熱可塑性樹脂のモノフィラメント等から構成されたマルチフィラメントである。前記モノフィラメントの断面は、図１のように、大きさを異にする６個の球状突起が対称的に形成されている。より具体的に、モノフィラメントの断面は、モノフィラメントの断面の長軸長さ（Ｌ１）を基準として、球状突起６個が上部面に２個、下部面に２個、左側面に１個、右側面に１個ずつ対称的に形成されている。モノフィラメントの断面において、前記モノフィラメントの断面の短軸長さ（Ｌ２）／モノフィラメントの断面の短軸幅（Ｄ１）の比は、１．０以上４．０以下であることが好ましい。Ｌ２／Ｄ１の比が１．０未満であると、その吸汗速乾性が低下する可能性がある。また、Ｌ２／Ｄ１の比が４．０を超過すると、その吸汗速乾性と作業性が低下する可能性がある。 First, the present invention is a multifilament composed of a monofilament or the like of a thermoplastic resin. In the cross section of the monofilament, six spherical protrusions having different sizes are formed symmetrically as shown in FIG. More specifically, the cross section of the monofilament is based on the long axis length (L 1 ) of the monofilament cross section, 6 spherical protrusions are 2 on the upper surface, 2 on the lower surface, 1 on the left side, 1 on the right side One piece is formed symmetrically on the surface. In the monofilament cross section, the ratio of the short axis length (L 2 ) of the monofilament cross section / the short axis width (D 1 ) of the cross section of the monofilament is preferably 1.0 or more and 4.0 or less. If the ratio of L 2 / D 1 is less than 1.0, the sweat-absorbing quick drying property may be lowered. Moreover, when the ratio of L 2 / D 1 exceeds 4.0, the sweat-absorbing quick drying property and workability may be deteriorated.
また、モノフィラメントの断面の長軸長さ（Ｌ１）／モノフィラメントの断面の短軸長さ（Ｌ２）の比は、１．０以上４．０以下であることが好ましい。この範囲を外れると、その吸汗速乾性と作業性が低下する可能性がある。 The ratio of the major axis length (L 1 ) of the cross section of the monofilament to the minor axis length (L 2 ) of the cross section of the monofilament is preferably 1.0 or more and 4.0 or less. If it is out of this range, the sweat-absorbing quick drying property and workability may be lowered.
本発明において、熱可塑性樹脂としては、ポリアミド、ポリエステル、又は、ポリアクリル等が使われることができ、より好ましくは、疎水性のポリエステルを使用することが好ましい。 In the present invention, as the thermoplastic resin, polyamide, polyester, polyacryl or the like can be used, and it is more preferable to use hydrophobic polyester.
本発明によるマルチフィラメント（原糸）は、大きさを異にする６個の突起が人体から発散された汗を外部に速かに排出させる通路として役割をするために、吸湿性が非常に優れるものとなる。また、本発明によるマルチフィラメント（原糸）は、大気と接触する表面積が非常に広くて、外部に排出させた汗を大気中に速かに蒸発させる性質（速乾性）が非常に優れるものとなる。 The multifilament (raw yarn) according to the present invention has a very high hygroscopicity because the six protrusions having different sizes serve as a passage for quickly discharging sweat discharged from the human body to the outside. It will be a thing. Further, the multifilament (raw yarn) according to the present invention has a very large surface area in contact with the atmosphere, and has a very excellent property (fast drying property) for quickly evaporating sweat discharged to the outside into the atmosphere. Become.
さらに、本発明によるマルチフィラメント（原糸）は、人体との接触面が少なく、多量の汗が排出された場合でも、衣類が体にまとわりつく現状を防止することができるので、着用感に優れる。また、本発明によるマルチフィラメント（原糸）は、単独で、又は、綿やポリプロフィレン原糸と混用して、ジャケット等の衣類製造に主に使用できる。 Furthermore, the multifilament (raw yarn) according to the present invention has a small contact surface with the human body, and even when a large amount of sweat is discharged, it can prevent the current situation where clothes are clinging to the body, and thus has a good wearing feeling. In addition, the multifilament (raw yarn) according to the present invention can be used mainly for the manufacture of clothing such as a jacket, alone or in combination with cotton or polypropylene raw yarn.
一方、本発明によるマルチフィラメント（原糸）は、その平均粒径０．１μｍ以上１．０μｍ以下の銀系無機抗菌剤を全体原糸の質量対比０．３質量％以上２．０質量％以下含有している。 On the other hand, the multifilament (raw yarn) according to the present invention has a silver-based inorganic antibacterial agent having an average particle size of 0.1 μm or more and 1.0 μm or less compared to 0.3% by weight or more and 2.0% by weight or less of the whole raw yarn. Contains.
前記銀系無機抗菌剤は、無機担体であるリン酸ジルコニウム（ＺｒＯ２Ｐ２Ｏ５）に銀（Ａｇ）が担持された抗菌剤であって、日本の東亜合性株式会社製“ＮＯＶＡＲＯＮ”（製品名）である。 The silver-based inorganic antibacterial agent is an antibacterial agent in which silver (Ag) is supported on zirconium phosphate (ZrO 2 P 2 O 5 ), which is an inorganic carrier, and “NOVARON” (manufactured by Toa Gosei Co., Ltd., Japan) Product name).
前記銀系無機抗菌剤は、その銀イオンが細菌に作用することにより、生命維持に要する代謝機能を阻害し、水と光の存在下で活性酸素（Ｏ２）を発生させることにより、細菌の細胞膜を破壊する。 The silver-based inorganic antibacterial agent inhibits the metabolic function required for life support by the action of silver ions on bacteria, and generates active oxygen (O 2 ) in the presence of water and light, thereby Destroy the cell membrane.
銀系無機抗菌剤は、その平均粒径が１．０μｍを超過すると、２デニール未満の細い原糸の製造が難しく、紡糸パックの圧力が大きく上昇し、作業性（ｆｕｌｌ−ｄｒｕｍ率）が大きく低下される。一方、その平均粒径が０．１μｍ未満であると、抗菌剤の分散性が悪くなり、作業性が低下され、原価が高くなる。 When the average particle size of the silver-based inorganic antibacterial agent exceeds 1.0 μm, it is difficult to produce a fine yarn of less than 2 denier, the pressure of the spinning pack is greatly increased, and workability (full-drum ratio) is large. Is lowered. On the other hand, when the average particle size is less than 0.1 μm, the dispersibility of the antibacterial agent is deteriorated, workability is lowered, and the cost is increased.
また、原糸内の銀系無機抗菌剤の含量が２．０質量％を超過すると、製造原価が高くなり、分散性が落ちて、その作業性が悪くなる。一方、原糸内の銀系無機抗菌剤の含量が０．３質量％未満であると、十分な抗菌機能を得られない。 Moreover, when the content of the silver-based inorganic antibacterial agent in the raw yarn exceeds 2.0% by mass, the manufacturing cost becomes high, the dispersibility is lowered, and the workability is deteriorated. On the other hand, when the content of the silver-based inorganic antibacterial agent in the raw yarn is less than 0.3% by mass, a sufficient antibacterial function cannot be obtained.
本発明によるマルチフィラメントは、図１のような工程を通じて製造することができる。図１は、本発明によるマルチフィラメントを製造する工程概略図である。 The multifilament according to the present invention can be manufactured through a process as shown in FIG. FIG. 1 is a schematic view of a process for manufacturing a multifilament according to the present invention.
具体的に、熱可塑性ポリマーチップの移送配管（１）を通して熱可塑性ポリマーチップを押出機（３）に供給すると同時に、前記銀系無機抗菌剤が添加されている熱可塑性ポリマーチップ［以下、“マスターバッチチップ（ｍａｓｔｅｒ ｂａｔｃｈ ｃｈｉｐ）”という］をサイドフィーダー（ｓｉｄｅ ｆｅｅｄｅｒ）（２）を通して上記の押出機（３）に供給する。次いで、押出機（３）に供給された熱可塑性ポリマーチップと銀系無機抗菌剤の添加された熱可塑性ポリマーチップ（マスターバッチチップ）とを溶融・混合する。 Specifically, the thermoplastic polymer chip is supplied to the extruder (3) through the thermoplastic polymer chip transfer pipe (1), and at the same time, the thermoplastic polymer chip to which the silver-based inorganic antibacterial agent is added [hereinafter referred to as “master”. A batch chip ”(referred to as master batch chip)” is fed to the extruder (3) through a side feeder (2). Next, the thermoplastic polymer chip supplied to the extruder (3) and the thermoplastic polymer chip (master batch chip) to which the silver-based inorganic antibacterial agent is added are melted and mixed.

この時、銀系無機抗菌剤を押出機（３）に直接投入することよりは、上記のように、マスターバッチチップを製造してから、このマスターバッチチップをサイドフィーダー（２）を通して、押出機（３）に供給することが、抗菌剤の分散性と作業性の側面でより好ましい。 At this time, rather than directly feeding the silver-based inorganic antibacterial agent into the extruder (3), the master batch chip is manufactured as described above, and then this master batch chip is passed through the side feeder (2) to the extruder. Supplying to (3) is more preferable in terms of dispersibility and workability of the antibacterial agent.
