【発明の属する技術分野】
本発明は、表面に銀層を有する繊維(以下、銀繊維という)及び獣毛繊維が用いられ、銀の有する性能の劣化防止加工が施された繊維製品に関するものであり、さらには上記製品の製造方法に関するものである。
【0002】
【従来の技術】
近年、携帯電話やコンピュータ類等の電子機器がオフィスや家庭等において広範囲に普及しており、これら電子機器の筐体には、小型化,生産性向上のためにプラスチックが多く用いられている。しかしながら、プラスチックは金属に比べて電磁的に何も存在しないものと等しく、筐体内部から照射される電磁波は筐体内外の電子機器の動作の信頼性を損なうばかりでなく、人体の諸器官にも障害を与え、使用者・作業員の健康に及ぼす影響も懸念されているため、人体に照射される電磁界の強度の軽減が求められ、この様な要求に対して様々な電磁波シールド性繊維構造物が開発されている。
【0003】
その例として、従来よりステンレスファイバー,金属被覆繊維,炭素繊維,黄銅繊維,アルミ繊維等の電磁波シールド性能を有する糸や、又はこの様な糸の形態の他に、製織後、表面に銀,ニッケル等の電磁波シールド性物質をコーティングを施した布帛等が知られている。
【0004】
金属を用いた電磁波シールド繊維の中でも、銀は下記に示すように極めて高い導電性を持ち、化学的に非常に不活性で大気によって腐食されにくく、また表面が酸化されても電気伝導性が低下しないばかりでなく、抗菌・消臭性能をも備えているため、衣料用途等に用いられており、例えば、ナイロン66からなるポリアミド繊維のフィラメントまたはステープルファイバーに銀をメッキした形態の銀被覆繊維が電磁波シールド繊維としてよく知られている。
【0005】
<金属の電気抵抗率>

【0006】
一方、天然繊維の分野において、獣毛繊維はその優れた吸放湿特性で、あらゆる中で最も理想的な繊維であるといわれている。特に羊毛は空気含有量が多く、空気の断熱効果を利用して断熱・保温性の衣料用素材として重用されている。
【0007】
そして、近年の電磁波の影響に関する問題意識や清潔志向の高まりを受け、本出願人は銀繊維と獣毛繊維との混紡、交織又は交編等の混用製品の開発を進めてきた。
【0008】
しかしながら、銀は微量の硫化水素が雰囲気中に含まれているだけであっても表面が硫化銀となり黒化するという性質があるため、上記混用製品を蒸気中で処理した場合等に、羊毛の主成分であるケラチン(C16H157N5SO15)から硫化水素(H2S)が発生し、これが銀の変色を引き起こして外観を損ねるだけでなく、導電性をも低下せしめるようになるので、その結果電磁波シールド性能の低下の原因となるという問題をも有していた。
【0009】
【発明が解決しようとする課題】
本発明は、上記の問題点に鑑みなされたものであって、銀繊維及び獣毛繊維が用いられ、上記の銀の劣化といった問題を解消し得る繊維構造物の提供、さらには、該繊維構造物の製造方法の提供を目的とするものである。
【0010】
【課題を解決するための手段】
上記の目的を達成するために、本発明は以下の構成をとる。
まず第一番目の発明は、表面に銀層を有する繊維と獣毛繊維とを混用して得られるものであって、且つ上記銀層の表層部が沃化していることを特徴とする銀/獣毛混用繊維構造物である。
【0011】
そして、第二番目の発明は、上記繊維構造物の製造方法であって、具体的には、表面に銀層を有する繊維と獣毛繊維とを混紡、交織又は交編して得た繊維構造物に、沃素を含有する処理液を付与することを特徴とする方法である。
【0012】
【発明の実施の形態】
以下、本発明の一実施形態に基づいて説明する。
本発明の複合繊維構造物としては、表面に銀層を有する繊維(銀繊維)と獣毛繊維とからなるものであれば、かせ糸等の糸の形態、織物・編み物・不織布等の布帛の形態、さらには上記の糸及び/又は布帛を用いた縫製品の形態などが該当する。
【0013】
表面に銀層を有する繊維、即ち本発明における「銀繊維」としては、上述の様にフィラメント又はステープルファイバー等の芯成分を銀メッキ処理したもので、特に芯成分がポリアミド系繊維である、所謂「銀被覆ナイロン繊維」が好適であるが、これに限定されるものではなく、繊維表面に銀が露出、または繊維表面が銀で被覆されているものであれば何れも使用することが可能である。
【0014】
好適な電磁波シールド性能を発揮する形態としては、獣毛繊維紡績糸1〜8本に対して、上記の銀被覆ナイロン繊維とポリエステル系繊維との混紡糸を1本織り込む様に交織した織物があり、スーツ,ユニフォーム,ニット製品の様な衣料用素材等として使用されている。図1に獣毛繊維紡績糸(1)を4本に対し、銀被覆ナイロン繊維とポリエステル系繊維の混紡糸(2)を1本織り込んだ交織布帛(3)の模式図を示す。
【0015】
なお、上記の銀被覆ナイロン繊維は、先述の様にナイロン66からなるフィラメントに銀をメッキ処理して被覆せしめたものであり、これを25〜78mmに切断し、ポリエチレンテレフタレート等を主成分とするポリエステル系繊維と混ぜ合わせ、混紡糸とするものである。
このとき、該混紡糸においては、銀被覆ナイロン繊維の含有量が0.2重量%以上であると抗菌性,制電性等を発揮し、また3.0重量%以上であると、電磁波シールド性能の点において好適となる。
【0016】
また、本発明において、獣毛繊維とは主に羊毛を指すが、これに限定するものではなく、その他にもカシミア、モヘア、アルパカ、ラクダ、ウサギ等も用いることが可能である。
【0017】
そして、以上に述べたような銀繊維と獣毛繊維を用いた銀/獣毛含有繊維構造物、具体的には、混紡糸又は該混紡糸を用いた布帛、或いは銀繊維と獣毛繊維の交織又は交編布帛を製造するのである。
【0018】
続いて、本発明の銀/獣毛含有繊維構造物の製造方法について説明する。
なお、以下の説明においては布帛、特に織物の形態の例について述べるが、上述の様に本発明の技術思想は布帛の場合のみに限定されるものではなく、かせ糸の形態や縫製品の形態等についても適用し得るものである。
【0019】
まず、上述の様に、図1に示される様な銀被覆ナイロン繊維とポリエステル繊維とを混ぜ合わせて混紡糸を紡出し、該混紡糸と獣毛繊維からなる紡績糸とを交織して、銀/獣毛繊維含有布帛を製織した後、該布帛は、まず沃素を含有する処理液で処理される。
【0020】
この沃素処理は、浸漬法や連続処理(パッド・スチーミング法)等で行われることが好ましい。このときの沃素付与量は、0.1〜200.0%owf、好ましくは0.5〜80%owfとすると、各繊維に損傷や過度の変質がなく、かつ銀被膜の最外層部分を沃化銀とすることが可能となり、その後の処理による銀の劣化を防止し得る様になるのである。
【0021】
なお、沃素は水には不溶であるため、「沃素を含有する処理液」を作成するにあたって希釈する場合、アルカリ性沃化物水溶液,アルコール,クロロホルム,エーテル,四塩化炭素等の溶媒を用いるが、この中ではアルカリ性沃化物水溶液、特に沃化カリウム水溶液が最も好ましい。
【0022】
そして、沃素処理を施された上記布帛は、続いて染色工程に投入される。染料としては、獣毛繊維を染色することが可能な酸性染料、含金属錯塩酸性染料、酸性媒染染料、反応性染料等を用い、50〜100℃、かつ20〜90分で染色する。また、上記の例の様に、ポリエステル系繊維を含有する場合、色合いによっては、獣毛繊維を染色するに先立って、分散染料を用いてポリエステル系繊維部分の染色を行っても良い。
【0023】
【実施例】
次に、本発明を実施例に基づいて詳細に説明する。
【0024】
まず、ナイロン66からなる0.16tex(1.4デニール)のポリアミド繊維フィラメントを無電解メッキ法により銀で被覆せしめた後、これを繊維長38mmに切断し、ステープルファイバー状にした。このとき、該銀被覆繊維における銀の重量比率が18重量%となる様にした。
【0025】
次いで、上記の銀被覆短繊維20重量%と、ポリエチレンテレフタレートを主成分とするレギュラーポリエステル80重量%を用い、撚数72回/m,70/2メートル番手の銀被覆繊維含有混紡糸を紡出した。
【0026】
さらに、メリノウールを用いて、常法により撚数72回/m,60/2メートル番手の純毛紡績糸を紡出した。そして、経糸・緯糸共に、上記純毛紡績糸4本に対して、上記の銀被覆短繊維含有混紡糸が1本混入される様に配置して経28.6本/cm,緯25.6本/cmの織り密度で交織し、銀被覆繊維と獣毛繊維のを含有する、目付168g/m2の交織布帛を製織した。
【0027】
(実施例1)
<沃素処理>
続いて、沃素処理液として、下記の処方の水溶液を作成し、該処理液と共に上記交織布帛をジェットウィンスに投入した。このとき、布帛への沃素の付与量が40.0%owf、浴比1:10となるようにした。そして、ジェットウィンス中において、20分×40℃で布帛を処理した。
【0028】
(沃素処理液の処方:水1リットル中の含有量)
沃素 2.7g/リットル
沃化カリウム 15.0g/リットル
ホウ酸 30.0g/リットル
【0029】
<染色処理>
その後、一旦上記の沃素処理液をジェットウィンスから排出し、続いてソーピングを行った。
そして、獣毛繊維可染染料である酸性染料をはじめとする薬剤を、布帛重量に対し下記の重量比となる様投入し、100℃×60分で羊毛部分を染色し、その結果得られた染色布帛を実施例1とした。なお、このときpH調整剤として極微量の酢酸を添加した。
Irgalan Blue FBL200 3.0重量%
(Ciba Specialty Chemicals社製、酸性染料)
Irgasol DAM 1.0重量%
(Ciba Specialty Chemicals社製、染色助剤)
無水芒硝 7.0重量%
【0030】
(比較例1)
次に、沃素処理も染色処理も施していない、未加工の布帛を比較例1の製品とした。
【0031】
(比較例2)
続いて、比較例1と同様の未加工交織布帛に対し、上記実施例1に記載した<沃素処理>を施さず、<羊毛染色>のみを行って得た製品を比較例2の製品とした。
【0032】
(比較例3)
さらに、比較例1と同様の未加工交織布帛に対し、上記実施例1に記載した<沃素処理>を施さず、家庭用洗濯機を用い、塩素を含む水道水によって20分間撹拌・洗浄し、次いで乾燥せしめ、これを比較例3の製品とした。
【0033】
以上の実施例1,比較例1,比較例2,比較例3の製品について、電気抵抗値及び電磁波(電界波)の遮蔽率を測定し、さらに、実施例1,比較例2,比較例3について、熟練した専門員による外観の黒色化状態の黙視検査を行った。
【0034】
なお、電気抵抗値は、テスターを用いて、測定端子を50mmの幅に固定して値を採取し、また、電界波の遮蔽率については、近傍電磁界シールド効果測定装置「ANRITSU:MA8602B」を用い、社団法人関西電子工業振興センターの定めるKEC法により測定した。
以下表1にその評価結果を示す。
【0035】
【表1】
【0036】
上記の比較例2,3のように、高温・高湿条件下である染色工程や、塩素を含有する水道水洗浄の工程に、沃素加工を施していない状態の銀繊維/獣毛繊維の交織布帛を投入すると、導電性が低下して(電気抵抗値が増加して)電磁波のシールド性能の低下を引き起こしたが、染色工程に先立って沃素加工を行った実施例1の製品の場合、比較例2、比較例3の布帛に比べても導電性の低下が少ないものであった。
【0037】
【発明の効果】
以上の説明の様に、本発明の繊維構造物は、銀で被覆された繊維を羊毛等の獣毛繊維と混用した製品であっても、電磁波の遮蔽性能や、導電性即ち帯電防止性能といった銀の特質を失わず、かつ獣毛繊維の保温性・断熱性を併せ持つ製品を提供することが可能になり、また本発明の方法によれば、上記の様な製品を容易に製造することが可能になるという効果を奏するのである。

BACKGROUND OF THE INVENTION
The present invention relates to a fiber product in which fibers having a silver layer on the surface (hereinafter referred to as silver fiber) and animal hair fibers are used, and the performance of silver has been prevented from being deteriorated. It relates to a manufacturing method.
[0002]
[Prior art]
In recent years, electronic devices such as mobile phones and computers have been widely used in offices and homes, and plastics are often used for the casings of these electronic devices in order to reduce the size and improve the productivity. However, plastic is equivalent to nothing electromagnetically present compared to metal, and electromagnetic waves radiated from the inside of the housing not only impair the reliability of the operation of electronic devices inside and outside the housing, but also to various organs of the human body. As a result, there is a concern about the effects on the health of users and workers, so it is necessary to reduce the intensity of the electromagnetic field applied to the human body. A structure has been developed.
[0003]
For example, in addition to conventional yarns having electromagnetic shielding performance such as stainless fiber, metal coated fiber, carbon fiber, brass fiber, aluminum fiber, etc., or in the form of such yarn, silver, nickel on the surface after weaving Fabrics that are coated with an electromagnetic shielding material such as the like are known.
[0004]
Among the electromagnetic shielding fibers using metal, silver has extremely high conductivity as shown below, it is chemically inert and hardly corroded by the atmosphere, and its electrical conductivity is reduced even if the surface is oxidized. As well as antibacterial and deodorant performance, it is used for apparel and the like, for example, a polyamide fiber filament made of nylon 66 or a silver coated fiber in the form of silver-plated staple fibers. It is well known as an electromagnetic shielding fiber.

[0006]
On the other hand, in the field of natural fibers, animal hair fibers are said to be the most ideal fibers of all because of their excellent moisture absorption and desorption characteristics. In particular, wool has a high air content and is used as a heat-insulating and heat-retaining clothing material by utilizing the heat insulating effect of air.
[0007]
Then, in response to the recent increase in awareness of problems related to the influence of electromagnetic waves and the increase in cleanliness, the present applicant has been developing mixed products such as blending, knitting or knitting of silver fibers and animal hair fibers.
[0008]
However, silver has the property that the surface becomes silver sulfide and blackens even if only a small amount of hydrogen sulfide is contained in the atmosphere. Therefore, when the above mixed product is treated in steam, Hydrogen sulfide (H 2 S) is generated from keratin (C 16 H 157 N 5 SO 15 ), which is the main component, and this not only deteriorates the appearance by causing discoloration of silver, but also decreases the conductivity. As a result, it also has a problem of causing a decrease in electromagnetic shielding performance.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and provides a fiber structure in which silver fibers and animal hair fibers are used, and which can solve the problems such as silver degradation. The object is to provide a method for manufacturing a product.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
The first invention is obtained by mixing fibers having a silver layer on the surface and animal hair fibers, and the surface layer portion of the silver layer is iodinated. It is an animal hair mixed fiber structure.
[0011]
The second invention is a method for producing the above fiber structure, specifically, a fiber structure obtained by blending, interweaving or knitting a fiber having a silver layer on the surface and an animal hair fiber. And a treatment liquid containing iodine is applied to the product.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a description will be given based on an embodiment of the present invention.
As the composite fiber structure of the present invention, as long as it is composed of a fiber (silver fiber) having a silver layer on the surface and animal hair fibers, the form of yarn such as skein, and the fabric such as woven fabric, knitted fabric, and non-woven fabric are used. The form, and further, the form of a sewing product using the above-described thread and / or fabric are applicable.
[0013]
The fiber having a silver layer on the surface, that is, the “silver fiber” in the present invention is a so-called silver-plated core component such as a filament or staple fiber as described above, and in particular, the so-called core component is a polyamide fiber. “Silver-coated nylon fiber” is preferred, but is not limited to this, and any fiber can be used as long as silver is exposed on the fiber surface or the fiber surface is coated with silver. is there.
[0014]
As a form that exhibits suitable electromagnetic wave shielding performance, there is a woven fabric in which one to eight blended yarns of the above-mentioned silver-coated nylon fibers and polyester fibers are woven into 1 to 8 animal fiber spun yarns. It is used as a material for clothing such as suits, uniforms and knitted products. FIG. 1 is a schematic diagram of an union fabric (3) in which one animal fiber spun yarn (1) is woven with one mixed yarn (2) of silver-coated nylon fibers and polyester fibers.
[0015]
The silver-coated nylon fiber is a nylon 66 filament coated with silver as described above, cut into 25 to 78 mm, and mainly composed of polyethylene terephthalate or the like. Blended with polyester fiber to make a blended yarn.
At this time, in the blended yarn, when the content of the silver-coated nylon fiber is 0.2% by weight or more, antibacterial properties and antistatic properties are exhibited, and when it is 3.0% by weight or more, the electromagnetic wave shield This is preferable in terms of performance.
[0016]
In the present invention, animal hair fiber mainly refers to wool, but is not limited to this, and cashmere, mohair, alpaca, camel, rabbit and the like can also be used.
[0017]
Then, a silver / animal hair-containing fiber structure using silver fibers and animal hair fibers as described above, specifically, a blended yarn or a fabric using the blended yarn, or silver fibers and animal hair fibers A woven or knitted fabric is produced.
[0018]
Then, the manufacturing method of the silver / animal hair containing fiber structure of this invention is demonstrated.
In the following description, an example of the form of a fabric, particularly a woven fabric, will be described. However, as described above, the technical idea of the present invention is not limited to the case of a fabric. Etc. are also applicable.
[0019]
First, as described above, a silver-coated nylon fiber and a polyester fiber as shown in FIG. 1 are mixed to spin a blended yarn, and the blended yarn and a spun yarn composed of animal hair fibers are interwoven to obtain a silver / After weaving the animal hair fiber-containing fabric, the fabric is first treated with a treatment solution containing iodine.
[0020]
This iodine treatment is preferably carried out by dipping or continuous treatment (pad steaming method). If the amount of iodine applied is 0.1 to 200.0% owf, preferably 0.5 to 80% owf, each fiber is not damaged or excessively deteriorated, and the outermost layer portion of the silver coating is in an iodine state. It becomes possible to make silver halide, and it becomes possible to prevent silver deterioration due to subsequent processing.
[0021]
In addition, since iodine is insoluble in water, a solvent such as an aqueous solution of alkaline iodide, alcohol, chloroform, ether, carbon tetrachloride, etc. is used when diluting when preparing a “treatment solution containing iodine”. Of these, an aqueous alkaline iodide solution, particularly an aqueous potassium iodide solution is most preferred.
[0022]
Then, the fabric subjected to the iodine treatment is subsequently put into a dyeing process. As the dye, an acid dye capable of dyeing animal hair fibers, a metal-containing complex hydrochloric acid dye, an acid mordant dye, a reactive dye, or the like is used and dyed at 50 to 100 ° C. for 20 to 90 minutes. Further, as in the above example, when the polyester fiber is contained, depending on the hue, the polyester fiber portion may be dyed using a disperse dye prior to dyeing the animal hair fiber.
[0023]
【Example】
Next, the present invention will be described in detail based on examples.
[0024]
First, a 0.16 tex (1.4 denier) polyamide fiber filament made of nylon 66 was coated with silver by an electroless plating method, and then cut into a fiber length of 38 mm to form a staple fiber. At this time, the weight ratio of silver in the silver-coated fiber was set to 18% by weight.
[0025]
Next, using the silver-coated short fibers 20% by weight and the regular polyester 80% by weight of polyethylene terephthalate as the main component, the number of twists of 72 times / m, 70/2 meters, and the yarn containing silver-coated fibers is spun. did.
[0026]
Further, pure wool spun yarn having a twist number of 72 times / m and 60/2 meters was spun by a conventional method using merino wool. For both the warp and weft yarns, the above-described four spun wool spun yarns are arranged so that one of the above silver-coated short fiber-containing blended yarns is mixed and warp 28.6 yarns / cm, weft 25.6 yarns. An interwoven fabric with a weight per unit area of 168 g / m 2 and woven with silver-coated fibers and animal hair fibers was woven.
[0027]
Example 1
<Iodine treatment>
Subsequently, an aqueous solution having the following formulation was prepared as an iodine treatment solution, and the union fabric was put into the jet wins together with the treatment solution. At this time, the amount of iodine applied to the fabric was 40.0% owf, and the bath ratio was 1:10. Then, the fabric was treated at 40 ° C. for 20 minutes in the jet wins.
[0028]
(Prescription of iodine treatment solution: Content in 1 liter of water)
Iodine 2.7 g / liter Potassium iodide 15.0 g / liter Boric acid 30.0 g / liter
<Dyeing process>
Thereafter, the iodine treatment solution was once discharged from the jet wins, and then soaped.
Then, an agent including an acid dye which is a dyeable animal fiber dye was added so as to have the following weight ratio with respect to the weight of the fabric, and the wool part was dyed at 100 ° C. × 60 minutes. A dyed fabric was designated as Example 1. At this time, a very small amount of acetic acid was added as a pH adjuster.

[0030]
(Comparative Example 1)
Next, an unprocessed fabric that was not subjected to iodine treatment or dyeing treatment was used as a product of Comparative Example 1.
[0031]
(Comparative Example 2)
Subsequently, a product obtained by performing only <wool dyeing> without applying the <iodine treatment> described in Example 1 above to the raw unwoven fabric similar to Comparative Example 1 was used as the product of Comparative Example 2. .
[0032]
(Comparative Example 3)
Furthermore, the raw unwoven fabric similar to Comparative Example 1 was not subjected to the <iodine treatment> described in Example 1 above, and was stirred and washed with tap water containing chlorine for 20 minutes using a household washing machine, Subsequently, it was dried to obtain a product of Comparative Example 3.
[0033]
With respect to the products of the above-described Example 1, Comparative Example 1, Comparative Example 2, and Comparative Example 3, the electrical resistance value and the shielding rate of electromagnetic waves (electric field waves) were measured. Further, Example 1, Comparative Example 2, and Comparative Example 3 A black-eye appearance was visually inspected by skilled specialists.
[0034]
The electrical resistance value is obtained by fixing the measurement terminal to a width of 50 mm using a tester, and the electric field wave shielding rate is measured by using a nearby electromagnetic field shielding effect measuring device “ANRITSU: MA8602B”. It was measured by the KEC method defined by Kansai Electronics Industry Promotion Center.
Table 1 shows the evaluation results.
[0035]
[Table 1]
[0036]
As in Comparative Examples 2 and 3 above, silver fiber / animal hair fiber interweaving without iodine processing in the dyeing process under high temperature and high humidity conditions and the process of washing with tap water containing chlorine When the fabric was introduced, the conductivity decreased (the electrical resistance value increased) and the electromagnetic wave shielding performance decreased, but in the case of the product of Example 1 in which iodine processing was performed prior to the dyeing process, the comparison was made. Even when compared with the fabrics of Example 2 and Comparative Example 3, the decrease in conductivity was small.
[0037]
【The invention's effect】
