Abstract
Description
本発明は、手提げ袋、小物入れ、化粧品袋、ハンドパッグ等の袋物や衣服の一部等に縫製することが可能で、光源に対する角度により種々の色彩に反射する従来の玉虫色反射フィルムやホログラムフィルムに、長めの菱目模様を組合わせて反射模様をより複雑にし、強度とファッション性を高めた複雑乱反射菱形フィルムに関する。 The present invention can be sewed on handbags, accessory cases, cosmetic bags, handbags, etc., or a part of clothes, etc., and in conventional iridescent reflective films and hologram films that reflect various colors depending on the angle to the light source, The present invention relates to a complex irregular reflection rhombus film that combines a long rhombus pattern to make the reflection pattern more complex, and has improved strength and fashionability.
玉虫色反射フィルムは特許文献１及び特許文献２に開示され、透明フィルムでありながら美しい玉虫色に反射するため、ポリエステルフィルム等と貼着して補強し、そのまま使用し、或いは細い糸状に切断して繊維に織り込み、美しい玉虫色の光沢ある布地素材を提供してきた。 The iridescent reflective film is disclosed in Patent Document 1 and Patent Document 2 and reflects a beautiful iridescent color while being a transparent film. Therefore, it is adhered to a polyester film or the like to be reinforced, used as it is, or cut into a thin thread to produce a fiber. We have been providing a beautiful iridescent glossy fabric material.
一方、ホログラム模様とは、ホログラフィーに使用する素子、すなわち、物体により回折を受けた光波（信号波）を、それらと干渉性のある他の光波（参照波）と干渉させ、生じた干渉縞を感光材料に記録して測定する本来の意味でのホログラムとは多少異なり、単に平滑なフィルムやシートの表面に可視光線の波長程度の長さの緻密な縞状の凹凸からなる模様や画像を刻設したものである。その結果、この加工面に光線があたると凹凸にって可視光線が乱反射して虹色に輝き、その色調は角度により変化する。このようにして二次元、三次元のホログラム加工が可能で、複雑な模様や立体形状を美しい模様として表現することができる。 On the other hand, a hologram pattern is an element used for holography, that is, a light wave (signal wave) diffracted by an object is caused to interfere with another light wave (reference wave) having interference with them, and the generated interference fringes are formed. It is slightly different from the original hologram that is recorded on a photosensitive material and measured, and simply a pattern or image consisting of fine stripes with a length of about the wavelength of visible light is engraved on the surface of a smooth film or sheet. It is set. As a result, when a light ray hits this processed surface, the visible light ray is irregularly reflected and shines in a rainbow color, and the color tone changes depending on the angle. In this way, two-dimensional and three-dimensional hologram processing is possible, and complicated patterns and three-dimensional shapes can be expressed as beautiful patterns.
ポリオレフィンフィルムを強く延伸し、該延伸フィルムを割って得た割繊維を縦、横に連続的に積層・熱融着した不織布（以下、割符〔登録商標〕とする）は、軽量で、通気性のある高強度素材として広く知られている。割符の材料となる割繊維は、ポリエチレン、ポリプロピレン等のポリオレフィンフィルムを強力に縦延伸し、得られたフィルムを叩き割るようにして繊維状にしている。この割繊維を縦、横に連続的に積層し、熱融着して得られる。 Nonwoven fabric (hereinafter referred to as Tally (registered trademark)) is a lightweight, breathable fabric that is obtained by strongly stretching a polyolefin film and splitting and thermally fusing the split fibers obtained by splitting the stretched film vertically and horizontally. It is widely known as a high strength material. The split fiber, which is the material of the tally, is made into a fiber shape by strongly longitudinally stretching a polyolefin film such as polyethylene or polypropylene and hitting the obtained film. This split fiber is obtained by continuously laminating vertically and horizontally and heat-sealing.
縦、横の割繊維の太さは自由であるが、本発明においては、一方の繊維を細く、他方の繊維をその３倍以上、好ましくは５〜２０倍太くした。細い繊維を横糸とすると、太い繊維からなる縦糸は横糸に対して直角に交叉せず、やや斜めに交叉させ、しかも傾斜角度を直角に対し±２〜１０度傾斜する２方向に熱融着した。その結果、太い繊維のみが目立ち、２方向の繊維が４〜２０度の角度で交叉するため、連続する菱形の地模様を形成する。 Although the thickness of the vertical and horizontal split fibers is arbitrary, in the present invention, one fiber is thinned, and the other fiber is three times or more, preferably 5 to 20 times thicker. When the thin fibers are wefts, the warp yarns made of thick fibers do not cross at right angles to the wefts, but are slightly crossed and heat-sealed in two directions with an inclination angle of ± 2 to 10 degrees with respect to the right angle. . As a result, only thick fibers are conspicuous, and fibers in two directions cross at an angle of 4 to 20 degrees, so that a continuous diamond-shaped ground pattern is formed.
玉虫色反射フィルムやホログラム模様フィルムは、その美しさのためにポリエステルフィルムで補強した後、繊維状にし、衣服の繊維と組合わせて美しい布地として使用されている。これらのフィルムは、それ自体では強度にも模様の変化にも限界があり、組合わせる繊維や紙の色や素材感に負うところが大きい。元来透明なフィルムそれ自体で縫製にも耐え、独立した装飾的素材として使用できる素材が望まれていた。 Because of its beauty, iridescent reflective films and holographic pattern films are reinforced with a polyester film, then made into a fiber and used as a beautiful fabric in combination with clothing fibers. These films themselves have limitations in strength and pattern change, and are greatly affected by the color and texture of the fibers and paper to be combined. Originally, a transparent film that can withstand sewing and be used as an independent decorative material has been desired.
本発明は、玉虫色反射フィルム或いはホログラム模様を施したフィルムと、割符による連続菱形地模様とを組合わせることにより、模様を一層複雑にし、複雑乱反射によって半透明であり、強度と柔軟性を有し、ファッション性の高い美しい模様を有し、強度もあるフィルム素材を提供するものである。 The present invention combines an iridescent reflective film or a film with a hologram pattern and a continuous rhombus ground pattern with tallys to make the pattern more complex, translucent by complex diffuse reflection, and has strength and flexibility. It is a film material that has a beautiful pattern with high fashionability and strength.
すなわち、玉虫色反射フィルム又はホログラム模様フィルムを、菱形メッシュ状不織布と貼着するにあたっては、玉虫色反射フィルム又はホログラム模様フィルムの貼着面にコロナ処理、オゾン処理又はその両者を施すことにより、ポリエチレンとの接着性を向上させる。その上で、溶融ポリエチレンを押出しながら、割符を融着させる。更に、割符面に低密度ポリエチレンを押出し積層することにより、縫製にも耐える袋物に相応しい素材を得ることができる。 That is, in attaching the iridescent reflective film or hologram pattern film to the rhombus mesh-shaped nonwoven fabric, the corona treatment, ozone treatment or both are applied to the adhesion surface of the iridescent reflective film or hologram pattern film, so that Improve adhesion. Then, the tally is fused while extruding the molten polyethylene. Furthermore, by extruding and laminating low density polyethylene on the tally surface, a material suitable for a bag that can withstand sewing can be obtained.
本発明により、玉虫色反射フィルムやホログラム模様フィルムの美しさに、割符による地紋のような連続菱目模様が加わることにより、模様に一段と深みが増し、しかも袋物や衣服の一部素材として相応しい柔軟性と強度とを併有することができる。 According to the present invention, a continuous rhombus pattern like a crest pattern is added to the beauty of iridescent reflective film and hologram pattern film, which further increases the depth of the pattern and is also suitable as a part material for bags and clothes. And strength.
玉虫色反射フィルムは屈折率が０．０３、好ましくは０．０６以上異なる２種類の透明な超薄膜を７５層以上、好ましくは１００層以上積層して得ることができる。この積層フィルムの両表面層にはやや厚めのスキン層が形成されている。 The iridescent reflective film can be obtained by laminating 75 or more layers, preferably 100 or more layers, of two kinds of transparent ultra-thin films having a refractive index of 0.03, preferably 0.06 or more. Slightly thicker skin layers are formed on both surface layers of this laminated film.
屈折率が異なる一方の樹脂としてはアクリル系樹脂を使用する。例えば、メチルアクリレート、エチルアクリレート、ブチルアクリレート、メチルメタクリレート、エチルメタクリレート、ブチルメタクリレート等の比較的低分子量のアクリル系モノマーの重合体を挙げることができる。場合によっては、上記のモノマーに他の共重合可能なモノマーとの共重合体であっても、アクリル系樹脂を主成分とするものは包含される。 An acrylic resin is used as one resin having a different refractive index. Examples thereof include polymers of relatively low molecular weight acrylic monomers such as methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, ethyl methacrylate, and butyl methacrylate. Depending on the case, even if it is a copolymer with said monomer and another copolymerizable monomer, what has an acrylic resin as a main component is included.
他方の樹脂としては、ポリエチレンテレフタレート（Ａ成分）、ポリエチレンテレフタレート弾性体（Ｂ成分）及び線状低密度ポリエチレン（Ｃ成分）のポリマーブレンドが使用される。 As the other resin, a polymer blend of polyethylene terephthalate (component A), polyethylene terephthalate elastic body (component B) and linear low density polyethylene (component C) is used.
Ａ成分のポリエチレンテレフタレートとしては１，４−ブタンジオールとテレフタール酸又はジメチルテレフタレートとの触媒的重縮合反応によって得られたものが好ましい。 Ｂ成分のポリエチレンテレフタレート弾性体は、エチレンテレフタレート基を含有し、弾性を有するポリマーであれば本発明の目的を達成するが、ポリエチレンテレフタレートとポリエチレングリコールとの共重合体、好ましくはブロック共重合体が用いられる。
Ｃ成分の線状低密度ポリエチレンは市販されている各種の線状低密度ポリエチレンを使用することができる。一般に比重０．８５〜０．９３、メルトインデックス（以下、ＭＩとする）１〜５０である。
The polyethylene terephthalate of component A is preferably one obtained by catalytic polycondensation reaction of 1,4-butanediol with terephthalic acid or dimethyl terephthalate. The polyethylene terephthalate elastic body of component B can achieve the object of the present invention as long as it contains an ethylene terephthalate group and has elasticity, but a copolymer of polyethylene terephthalate and polyethylene glycol, preferably a block copolymer is used. Used.
As the C component linear low density polyethylene, various commercially available linear low density polyethylenes can be used. In general, the specific gravity is 0.85 to 0.93, and the melt index (hereinafter referred to as MI) is 1 to 50.
Ａ成分とＢ成分とＣ成分との配合比率は、Ａ成分：Ｂ成分：Ｃ成分＝８０〜９５：３〜１５：０．５〜５重量％、好ましくは８５〜９３：５〜１０：１〜４重量％である。Ｂ成分の比率が１５重量％を越えると透明性が阻害され、３重量％未満では耐衝撃性が改善されず、フィルム全体としての強度が増加しない。Ｃ成分が５重量％を越えると透明性が阻害され、０．５重量％未満では耐衝撃性が改善されない。
Ａ成分、Ｂ成分及びＣ成分の３成分を溶融混練して本発明のフィルムの一方の超薄層として使用する。
The blending ratio of the A component, the B component, and the C component is as follows: A component: B component: C component = 80 to 95: 3 to 15: 0.5 to 5% by weight, preferably 85 to 93: 5 to 10: 1. ~ 4% by weight. If the ratio of the component B exceeds 15% by weight, the transparency is inhibited, and if it is less than 3% by weight, the impact resistance is not improved and the strength of the entire film does not increase. If the C component exceeds 5% by weight, the transparency is inhibited, and if it is less than 0.5% by weight, the impact resistance is not improved.
The three components of component A, component B and component C are melt kneaded and used as one ultrathin layer of the film of the present invention.
本発明の玉虫色反射フィルムを構成する樹脂は上記に限定されるものではなく、ポリブチレンテレフタレートとポリメチルメタクリレートとの組合わせ、ポリブチレンテレフタレートとエチレンビニルアセテート、ポリエチレンテレフタレートとエチレンビニルアセテートとの組合わせ等を挙げることができる。 The resin constituting the iridescent reflective film of the present invention is not limited to the above, but a combination of polybutylene terephthalate and polymethyl methacrylate, a combination of polybutylene terephthalate and ethylene vinyl acetate, or a combination of polyethylene terephthalate and ethylene vinyl acetate. Etc.
本発明のフィルムは、２機の押出機のそれぞれから樹脂溶融物を捕集し、これらを希望する層パターンに配列するためのフィードブロックと通常のシングルマニホールドフラットフィルムダイとを組合わせた冷却ロールキャスティング法によって製造される。
このフィードブロックは２成分交互層を形成するのに用いられる。非常に細い複数層の樹脂の流れがシングルマニホールドフラットフィルムダイを通して流れ、そこで各層が同時にダイの幅まで拡張され、最終ダイの出口の厚さまで肉薄化される。層厚の分布は異なったフィードボードモジュールを挿入することにより変更できる。通常最外層は他の層より厚く、これをスキン層と呼ぶ。
The film of the present invention is a cooling roll that combines a feed block for collecting resin melts from each of two extruders and arranging them in a desired layer pattern and a normal single manifold flat film die. Manufactured by the casting method.
This feed block is used to form a two-component alternating layer. A very thin multi-layer flow of resin flows through a single manifold flat film die where each layer is simultaneously expanded to the width of the die and thinned to the exit die thickness. The distribution of layer thickness can be changed by inserting different feedboard modules. The outermost layer is usually thicker than the other layers and is called the skin layer.
本発明のホログラムフィルムの基材は、ポリエチレンテレフタレート、ポリアミド、塩化ビニル、ポリエチレン等特に限定はない。ホログラム加工は市販されるホログラム加工機により容易に行われる。例えば、米国、DIMENTIONAL ARTS 社製の「DAVIS LIGHT MACHINE 」又は「 LIGHT MACHINE」により加工することができる。干渉性の大きいレーザー光により平滑な表面に可視光線の波長程度、３８０〜８００ｎｍの凹凸を刻設する。
この凹凸を保護するために、ホログラム加工されたフィルム基材の両面又は片面を二酸化アルミニウム、硫化アンチモン等の透明金属化合物の薄層を被覆する。
The substrate of the hologram film of the present invention is not particularly limited, such as polyethylene terephthalate, polyamide, vinyl chloride, and polyethylene. Hologram processing is easily performed by a commercially available hologram processing machine. For example, it can be processed by “DAVIS LIGHT MACHINE” or “LIGHT MACHINE” manufactured by DIMENTIONAL ARTS, USA. Irregularities of about 380 to 800 nm are engraved on the smooth surface with a laser beam having high coherence.
In order to protect the unevenness, a thin layer of a transparent metal compound such as aluminum dioxide or antimony sulfide is coated on both sides or one side of the hologram-processed film substrate.
本発明の割符は、縦方向に配列する割繊維と横方向に配列する割繊維の断面積が極端に異なる。一方の割繊維の断面積に対する他方の割繊維の断面積は３倍以上、好ましくは５〜２０倍である。３倍以下であると地模様としての連続菱目模様が明瞭でなく、模様として単調である。２０倍を越えると細い繊維を配列した方向の強度が低下して好ましくない。 In the tally of the present invention, the cross-sectional areas of the split fibers arranged in the vertical direction and the split fibers arranged in the horizontal direction are extremely different. The cross-sectional area of the other split fiber with respect to the cross-sectional area of one split fiber is 3 times or more, preferably 5 to 20 times. If it is 3 times or less, the continuous rhombus pattern as the ground pattern is not clear and the pattern is monotonous. If it exceeds 20 times, the strength in the direction in which fine fibers are arranged is lowered, which is not preferable.
細い繊維をほぼ一定の間隔で配列した後に、太い繊維を細い繊維の配列方向とほぼ直角方向に配列する。この際、太い方の繊維を２分し、一方を細い繊維に対し９０−２〜１０度、好ましくは９０−４〜８度の角度で相互に平行に並べる。他方の太い繊維を、細い繊維に対し９０＋２〜１０度、好ましくは９０＋４〜８度の角度で相互に平行に並べる。この状態で熱融着することにより本発明の割符が得られる。この割符は、太い方の繊維が２方向に配列しており、その結果、太い繊維により連続した細長い菱形が連続して並ぶ模様になる。 After the fine fibers are arranged at substantially constant intervals, the thick fibers are arranged in a direction substantially perpendicular to the arrangement direction of the thin fibers. At this time, the thicker fiber is divided into two, and one of them is arranged parallel to each other at an angle of 90-2 to 10 degrees, preferably 90-4 to 8 degrees, with respect to the thin fibers. The other thick fibers are aligned parallel to each other at an angle of 90 + 2 to 10 degrees, preferably 90 + 4 to 8 degrees, with respect to the thin fibers. The tally of the present invention can be obtained by heat fusion in this state. In this tally, the thicker fibers are arranged in two directions, and as a result, a continuous long and narrow rhombus is continuously arranged by the thick fibers.
本発明の割符は、１５〜３５ｇ／ｍ2 であることが好ましい。１５ｇ／ｍ2 未満では連続した菱形が目立たず、模様として充分な存在感がない。一方３５ｇ／ｍ2 を越えると複雑乱反射菱形フィルムが強張り、柔軟性に欠けて素材フィルムとして扱い難い。 The tally of the present invention is preferably 15 to 35 g / m 2 . If it is less than 15 g / m 2 , the continuous rhombus does not stand out, and there is no sufficient presence as a pattern. On the other hand, if it exceeds 35 g / m 2 , the complex irregular reflection rhombus film is strong and lacks flexibility and is difficult to handle as a material film.
複雑乱反射菱形フィルムを製造するにあたっては、玉虫色反射フィルム又はホログラムフィルムの上に、低密度ポリエチレンを押出し積層すると共に割符を重ね合わせ、玉虫色反射フィルム又はホログラムフィルムと割符をポリエチレン層を介して一挙に積層する。押出しするポリエチレン層の厚みは限定がなく、玉虫色反射フィルム又はホログラムフィルムと割符を確実に積層するに充分な厚みであればよい。一般には、１０〜４０μｍである。更に割符の上から低密度ポリエチレンを押出し積層して完成する。最後に積層するポリエチレンの厚みも特に限定がなく、割符の太い繊維による凹凸が多少残り、且つ、割符を確実に覆う厚みであればよく、一般には２０〜５０μｍである。 When manufacturing a complex irregular reflection rhombus film, low density polyethylene is extruded and laminated on the iridescent reflective film or hologram film, and the tally is laminated, and the iridescent reflective film or hologram film and the tally are laminated at once through the polyethylene layer. To do. There is no limitation on the thickness of the polyethylene layer to be extruded, as long as it is sufficient to reliably laminate the iridescent reflective film or hologram film and the tally. Generally, it is 10-40 micrometers. Further, low density polyethylene is extruded and laminated from above the tally. The thickness of the polyethylene to be finally laminated is not particularly limited, and may be any thickness as long as the unevenness due to the thick tally fibers remains and covers the tally reliably, and is generally 20 to 50 μm.
得られた複雑乱反射菱形フィルムは、連続菱目模様の地紋の上にホログラムや玉虫色反射フィルムの模様が浮かび、深みのある半透明なフィルムである。しかも、しなやかで強靱であり、種々の半装飾的用途に加工するのが容易な素材である。太い繊維により形成された連続菱目模様は、細い繊維がほぼ直角に交叉しているため、菱目を形成する線条は細い繊維による横断方向の模様となり、菱目模様を一段と深みのある模様にしている。 The obtained complex irregular reflection rhombus film is a deep translucent film in which a pattern of a hologram or an iridescent reflection film floats on a background pattern of a continuous rhombus pattern. Moreover, it is a flexible, tough material that is easy to process into various semi-decorative applications. In the continuous rhombus pattern formed by thick fibers, the thin fibers intersect almost at right angles, so the striations forming the rhombus form a transverse pattern by the thin fibers, making the rhombus pattern a deeper pattern. I have to.
