Description
本発明は、布帛表面に露出している繊維の露出部分を加熱溶融して布帛表面を平滑にし、或いは布帛表面の色調を変え、或いは表面に図柄を描出する布帛表面仕上法に関するものである。 The present invention relates to a fabric surface finishing method in which exposed portions of fibers exposed on a fabric surface are heated and melted to smooth the fabric surface, change the color of the fabric surface, or draw a pattern on the surface.
熱可塑性繊維に成る立毛面を部分的に加圧して超音波振動を与え、熱可塑性繊維に成る立毛繊維を加熱溶融して立毛面に凹凸図柄を描出することは公知である(例えば、特許文献1と特許文献2参照)。
熱可塑性繊維に成る立毛面に感光発熱物質を印捺して近赤外線を照射し、その熱可塑性繊維に成る立毛繊維を感光発熱物質を介して加熱溶融し、もって立毛面に凹凸図柄を描出することは公知である(例えば、特許文献3と特許文献4と特許文献5参照)。
熱可塑性繊維に成る立毛布帛にレーザー光線を部分的に照射し、部分的にパイルを加熱溶融して凹部を形成し、もって立毛面に凹凸図柄を描出することは公知である(例えば、特許文献6と特許文献7と特許文献8参照)。
It is known to partially pressurize a raised surface made of thermoplastic fiber to give ultrasonic vibration, heat and melt the raised fiber made of thermoplastic fiber to draw an uneven pattern on the raised surface (for example, Patent Documents) 1 and Patent Document 2).
Imprint a photosensitive exothermic material on the raised surface made of thermoplastic fiber, irradiate near infrared rays, heat and melt the raised fiber made of thermoplastic fiber through the photosensitive exothermic material, and draw an uneven pattern on the raised surface Are known (see, for example, Patent Document 3, Patent Document 4, and Patent Document 5).
It is known that a raised fabric made of thermoplastic fiber is partially irradiated with a laser beam, and the pile is partially heated and melted to form a recess, thereby drawing an uneven pattern on the raised surface (for example, Patent Document 6). And Patent Document 7 and Patent Document 8).
上記従来技術は、加熱溶融に伴って熱可塑性繊維が熱収縮して生じる凹部と、加熱されない熱可塑性繊維の非加熱部分が相対的に構成することになる凸部との間の凹凸差によって布帛表面に図柄を描出しようとするものであり、その凹部には熱可塑性繊維が加熱溶融して固化した溶融塊が生じ、その溶融塊によって布帛表面の風合いが粗硬になる。
勿論、布帛表面にブラッシング処理を施し、或いは、布帛全体に振動を与えて揉み解すリラックス処理を施して、その溶融塊を細分する方法もある。
しかし、そのような図柄描出後に仕上処理を行えば、その分だけ布帛の製造コストが高くなり、又、布帛表面が不規則に毛羽立って疲労したかの観を呈し、それを修復するために布帛表面に整毛処理を施せば製造コストが更に高くなる。
The above-mentioned prior art is a fabric by the unevenness difference between the concave part which is caused by heat shrinkage of the thermoplastic fiber with heat melting and the convex part which the non-heated part of the thermoplastic fiber which is not heated constitutes relatively. A pattern is to be drawn on the surface, and in the concave portion, a molten lump is formed in which the thermoplastic fiber is heated and melted and solidified, and the texture of the fabric surface becomes coarse due to the molten lump.
Of course, there is also a method in which the surface of the fabric is subjected to a brushing process, or a relaxation process is applied to apply vibration to the entire fabric to break it up, and the molten mass is subdivided.
However, if the finishing process is performed after drawing such a pattern, the production cost of the fabric is increased by that amount, and the fabric surface has an irregular fluffy and fatigued view. If the surface is subjected to hair conditioning treatment, the manufacturing cost is further increased.
そこで本発明は、大きい溶融塊を発生させることなく、布帛表面にレーザー光線を照射し、布帛表面に露出している繊維の露出部分を加熱溶融して布帛表面を平坦にし、或いは布帛表面の色調を変え、或いは表面に図柄を描出し、製造コストを割高にすることなく布帛表面を仕上げることを目的とする。 Therefore, the present invention irradiates the surface of the fabric with a laser beam without generating a large melted lump, heats and melts the exposed portion of the fiber exposed on the fabric surface, and flattens the fabric surface or changes the color tone of the fabric surface. The purpose is to finish the surface of the fabric without changing or drawing the design on the surface and increasing the manufacturing cost.
即ち、超音波振動による従来技術(特許文献1と2)では、超音波振動を熱可塑性繊維に伝える装置(ホーン)を布帛表面に圧着せざるを得ず、又、近赤外線による従来技術(特許文献3と4)では印捺糊剤によって熱可塑性繊維間が仮接合状態にあり、而も、感光発熱物質が熱可塑性繊維に直接触れているので溶融塊の大きさを制禦することは出来ないが、レーザー光線による従来技術(特許文献5と6と7)では、熱可塑性繊維の加熱手段が質量のない電磁波であって繊維間の接触を強制するものではなく、その照射箇所に揮発(蒸発)性の放熱手段を施すときは、それによって加熱温度が極く限られた細部において制禦され、その放熱手段が繊維間を分離状態に維持する剥離剤としても機能し、溶融塊が細分されるとの知見を得て本発明が完成された。 That is, in the prior art based on ultrasonic vibration (Patent Documents 1 and 2), a device (horn) that transmits ultrasonic vibration to the thermoplastic fiber must be pressure-bonded to the fabric surface. In References 3 and 4), the thermoplastic fibers are temporarily joined by the printing paste, and the size of the molten mass cannot be controlled because the photosensitive exothermic material is in direct contact with the thermoplastic fibers. However, in the prior art using laser beams (Patent Documents 5, 6 and 7), the heating means of the thermoplastic fiber is an electromagnetic wave having no mass and does not force the contact between the fibers, and volatilizes (evaporates) at the irradiated part. ) When the heat dissipation means is applied, the heating temperature is controlled by the very limited details, and the heat dissipation means also functions as a release agent that keeps the fibers separated, and the molten mass is subdivided. The knowledge There has been completed.

It is in the point scattered more in the groove wall surface than the bottom.
液体が付着して湿潤状態にある布帛表面では、その液体が繊維の表面に薄い皮膜を形成しており、レーザー光線を受けて溶融する熱可塑性繊維の布帛表面露出部分が形成する溶融塊に触れて揮発(蒸発)するとき、その気化熱を奪って溶融塊の肥大化を妨げると共に、液体が繊維ポリマーとは異質の物質なので隣合う繊維の溶融塊と溶融塊の間に剥離剤の如く介在して、溶融塊同士が触れ合って肥大化するのを妨げる。
このため、レーザー光線の照射箇所では布帛表面露出繊維が大きい溶融塊を形成することなく加熱溶融し、布帛表面に外観上の変化を齎す。
On the surface of the fabric in which the liquid adheres and is in a wet state, the liquid forms a thin film on the surface of the fiber, and touches the molten mass formed by the exposed portion of the surface of the thermoplastic fiber melted by receiving the laser beam. When volatilizing (evaporating), it takes away the heat of vaporization and prevents the molten mass from being enlarged, and since the liquid is a different substance from the fiber polymer, it is interposed as a release agent between the molten mass of adjacent fibers and the molten mass. This prevents the molten mass from touching each other to enlarge.
For this reason, the fabric surface exposed fiber is heated and melted without forming a large melted lump at the laser beam irradiation site, and changes in the appearance of the fabric surface are caused.
液体を繊維に馴染み易くし、繊維表面に液体による皮膜が形成され易くするために、液体を、その液体に対して溶解性、分散性、または、吸着性を示す親水性物質との混合組成物に調製して、液体に粘着性を付与するとよい。 Mixture composition of liquid with hydrophilic substance that is soluble, dispersible, or adsorbable with respect to the liquid in order to make the liquid easy to conform to the fiber and to form a film with the liquid on the fiber surface. It is recommended that the liquid be made sticky.
その外観上の変化は、次のように布帛表面に顕現する。
(1) 液体を布帛全面に付着し、この布帛表面全体にレーザー光線を照射するときは、表面露出繊維の形状の変化に伴って光の反射具合が変化し、光沢や色調濃淡の変化となって顕現し、布帛表面毛羽が抑えられて布帛表面が平滑に仕上がる。
(2) 液体を布帛表面に部分的に付着し、その付着箇所にレーザー光線を照射するとき、或いは、液体を布帛表面の全面に付着させてレーザー光線を部分的に照射するときは、表面露出繊維の加熱溶融の有無によって布帛表面に図柄が描出される。
The change in appearance is manifested on the fabric surface as follows.
(1) When a liquid is attached to the entire surface of the fabric and the entire surface of the fabric is irradiated with a laser beam, the reflection of the light changes with the change in the shape of the surface exposed fibers, resulting in changes in gloss and tone. As a result, the fabric surface fluff is suppressed and the fabric surface is finished smoothly.
(2) When the liquid is partially attached to the fabric surface and the laser beam is applied to the attachment site, or when the liquid is applied to the entire surface of the fabric and the laser beam is partially applied, the surface exposed fiber A pattern is drawn on the surface of the fabric depending on the presence or absence of heat melting.
熱可塑性繊維が、その横断面の輪郭に凹凸、または、その横断面の内部に空洞を有する異形断面繊維では、その横断面に凹部や空洞となって現れる部分を溶融物が充填して表面積の少ない球形の溶融塊を形成することになるが、その溶融塊は溶融物が凹部や空洞を充填した分だけ形が小さくなり、手触りを感じさせず、表面に凹凸や空洞のある形状から表面に凹凸や空洞のない球形溶融塊へと繊維が変形して光沢が変化するので、布帛の外観を大きく変化させることが出来る。 If the thermoplastic fiber is irregular in the cross-sectional profile, or if it has a deformed cross-section fiber with a cavity inside the cross-section, the melt fills the part that appears as a recess or a cavity in the cross-section. A small spherical molten mass will be formed, but the molten mass will become smaller as the melt fills the recesses and cavities, and it will not feel the touch, and from the shape with irregularities and cavities on the surface to the surface Since the fibers are deformed into a spherical molten mass having no irregularities or cavities and the gloss changes, the appearance of the fabric can be greatly changed.
熱可塑性繊維が、染料、顔料、艶消剤、その他の繊維ポリマーとは異質の異質物質を有するものでは、それらが球形を成していて光の乱反射の少ない溶融塊の表面に現れるので、加熱溶融箇所が濃色になり、レーザー光線を局部的に照射するとき顕現する図柄が鮮明になる。 If the thermoplastic fibers have a foreign material that is different from dyes, pigments, matting agents, and other fiber polymers, they will appear on the surface of the molten mass with a spherical shape and less diffuse reflection of light. The melted portion becomes dark and the pattern that appears when the laser beam is irradiated locally becomes clear.
布帛が、起毛毛羽層と基布層から成る起毛二層構造布帛、パイル層と基布層から成るパイル二層構造布帛、表糸と裏糸が表裏に織編分けられている二層構造布帛、表布と裏布を連結糸によって連結されて一体化している立体二層構造布帛等の二層構造布帛である場合は、その上層を構成する毛羽やパイル、表糸、或いは表布の熱可塑性繊維が大きく加熱溶融しても、下層を構成している基布や裏糸、或いは裏布によって布帛の物性強度を保つことが出来るので、その上層の熱可塑性繊維を大きく加熱溶融させて凹凸差の大きい凹部による立体的凹凸図柄を布帛表面に描出することが出来る。 The fabric is a raised two-layer structure fabric comprising a raised fluff layer and a base fabric layer, a pile two-layer structure fabric comprising a pile layer and a base fabric layer, and a two-layer structure fabric in which the front and back yarns are woven and knitted on the front and back In the case of a two-layer structure fabric such as a three-dimensional two-layer structure fabric in which the front fabric and the back fabric are connected and integrated by a connecting yarn, the heat of the fuzz, pile, front yarn, or front fabric constituting the upper layer Even if the plastic fiber is heated and melted greatly, the physical strength of the fabric can be maintained by the base fabric, backing yarn, or backing fabric that constitutes the lower layer. A three-dimensional concavo-convex pattern due to a recess having a large difference can be drawn on the fabric surface.
本発明によると、表面露出繊維の加熱溶融して形成される凹部において、燈したローソクから水面に垂れ落ちる蝋が水に触れて固まるように、熱可塑性繊維の溶融物が、熱可塑性繊維に付着している液体に触れ顆粒状に固まって凹部の壁面に固着し、その凹部の中央部に介在し難くなる。
このため、レーザー光線は、その凹部の中央部(底部)に介在する溶融物に遮られるようなことはなく、布帛内部に奥深く入り込み、裏面に達する程度に深い凹部を形成することが出来る。
従って、静電植毛布帛、フエルト、起毛布帛、シェニール織物、モケット、別珍、コール天等の織パイル布帛、トリコットやダブルラッシェル等の編パイル布帛等の表面立毛層と裏面基布層との二層構造を成す有毛布帛に本発明を適用し、有毛パイル面に溝が刻設する場合、その溝の向き合う溝壁面が溝底に向けて傾斜した恰好になり、その溝が概してV字形断面を成し、その溝壁面に毛羽パイル繊維が溶融した最大寸法300μm以下の顆粒状の溶融塊が点在するように有毛パイル面に溝を刻設することが出来る。
そして、そのように最大寸法300μm以下の顆粒状の溶融塊は、指先で触っても硬い異物に触れたかの如き感触を与えることはないので、立体的凹凸図柄の描出された肌触りのよい有毛布帛を得ることが出来る。
According to the present invention, the melt of the thermoplastic fiber adheres to the thermoplastic fiber so that the wax dripping from the drowned candle onto the water surface is solidified by contact with water in the recess formed by heating and melting the surface-exposed fiber. It touches the liquid that is in contact and solidifies in a granular form and adheres to the wall surface of the recess, making it difficult to intervene in the center of the recess.
For this reason, the laser beam is not interrupted by the melt interposed in the central portion (bottom portion) of the concave portion, and can deeply enter the fabric and form a deep concave portion to reach the back surface.
Therefore, two layers of a surface raised layer and a back surface base fabric layer such as electrostatic flocked fabric, felt, brushed fabric, chenille fabric, moquette, benjin, woven pile fabric such as coal heaven, knitted pile fabric such as tricot and double raschel, etc. When the present invention is applied to a hairy fabric having a structure, and grooves are engraved on the surface of the hairy pile, the groove wall surfaces facing each other are inclined toward the groove bottom, and the grooves are generally V-shaped in cross section. The grooves can be engraved on the surface of the bristle pile so that granular molten masses with a maximum dimension of 300 μm or less in which the fluff pile fibers are melted are scattered on the groove wall surface.
In addition, such a granular molten mass having a maximum dimension of 300 μm or less does not give a touch as if it touched a hard foreign object even if it is touched with a fingertip. Can be obtained.
レーザー光線を照射して貫通孔や切り込みを布帛に付けることが出来、その貫通孔や切り込みの周縁に熱可塑性繊維の溶融物が固着することになるが、本発明によると、その熱可塑性繊維の溶融物が最大寸法300μm以下の細かい顆粒状の溶融塊となるので、その貫通孔や切り込みの周縁に硬い異物(溶融物)が固着していると感じられる異物感はなく、又、貫通孔や切り込みの周縁の熱可塑性繊維が細かい顆粒状の溶融塊となって固着しているので、その貫通孔や切り込みの周縁から布帛が解れ出すようなことも起こらない。 By irradiating a laser beam, a through hole or notch can be attached to the fabric, and a melt of the thermoplastic fiber is fixed to the periphery of the through hole or notch. According to the present invention, the thermoplastic fiber is melted. Since the object becomes a fine granular molten mass with a maximum dimension of 300 μm or less, there is no foreign object feeling that hard foreign matter (melt) is fixed to the periphery of the through hole or notch, and the through hole or notch Since the thermoplastic fibers at the periphery of the material are fixed as a fine granular molten mass, the fabric does not unravel from the through-holes or the periphery of the cut.
本発明では、レーザー光線発振装置から発射されて直進するレーザー光線を第一鏡面において反射し、その反射されたレーザー光線を第二鏡面において再び反射して布帛表面に照射することとし、それら第一鏡面と第二鏡面を揺動して鏡面でのレーザー光線の反射角度を変えて布帛表面の所要箇所へのレーザー光線の照射位置を合わせることとし、そのレーザー光線の照射位置を合わせるために発振装置や鏡面の位置を移動させないので、布帛表面の所要箇所に所要熱量のレーザー光線を正確に照射し、柄ズレを起こすことなく、所要の位置にレーザー光線によって図柄を正確に描出することが出来る。 In the present invention, the laser beam emitted from the laser beam oscillation device and traveling straight is reflected on the first mirror surface, and the reflected laser beam is reflected again on the second mirror surface to irradiate the fabric surface. Swing the two mirror surfaces to change the reflection angle of the laser beam on the mirror surface to match the laser beam irradiation position to the required location on the fabric surface, and move the position of the oscillation device and mirror surface to match the laser beam irradiation position Therefore, it is possible to accurately irradiate a required portion of the fabric surface with a laser beam having a required amount of heat and accurately draw a pattern with a laser beam at a required position without causing a pattern shift.
図1は、レーザー光線発振装置を図示し、レーザー光線11は、レーザー発振装置から発射され、焦点補正レンズ12を通って第一鏡面13へと直進し、第一鏡面13と第二鏡面14で反射して布帛表面15に照射される。第一鏡面13の回転中心16は、第一鏡面13の表面に設定され、その第一鏡面の回転中心線上(16)にレーザー光線11が照射される。従って、第一鏡面13が揺動回転しても、第一鏡面上での照射位置17が変わることはない。
第二鏡面の回転中心18は、第二鏡面14の表面であり、且つ、第一鏡面13でのレーザー光線の反射光19が照射される位置に設定されている。
FIG. 1 illustrates a laser beam oscillation device. A laser beam 11 is emitted from the laser oscillation device, travels straight through a
The
第一鏡面の回転中心軸16と第二鏡面の回転中心軸18とは、90度方向を異にするので、レーザー光線の第一鏡面での反射角度が、第一鏡面の揺動回転角度αに応じて変化しても、その第一鏡面でのレーザー光線の反射光19a・19b・19c・19dは常に、第二鏡面の回転中心軸線上18において再反射され、その再反射光20a・20b・20c・20dの布帛表面15での照射位置21a・21b・21cは、第一鏡面の揺動回転角度αの変化に伴って第二鏡面の回転中心軸18に平行する直線Xの上で移動する。
一方、第二鏡面14が揺動回転するとき、第二鏡面での再反射光20a・20a’・20b’は、その回転角度βに応じて方向を変え、布帛表面15での照射位置21a・21a’・21b’は、第一鏡面の回転中心軸16に平行な直線Yの上で移動する。
Since the rotation center axis 16 of the first mirror surface and the
On the other hand, when the
このため、第一鏡面13と第二鏡面14を揺動回転駆動すると、それらの回転角度(α・β)に応じて、布帛表面15でのレーザー光線の照射位置21を自由に移動することが出来る。
このように布帛表面での照射位置21が移動すると、焦点補正レンズ12から照射位置21に到るレーザー光線11の経路の全長が変化する。
22は、第一鏡面13の回転角度αの変位量Δαと第二鏡面14の回転角度βの変位量Δβによって、その変化する焦点補正レンズ12から照射位置21(21a・21a’・21b’・21b・21c………)に到るレーザー光線11の経路の全長を算出する距離演算素子であり、その距離演算素子22からの算出情報を受けて焦点補正レンズ12が作動し、レーザー光線の焦点が布帛表面の所要の照射位置21に合わされる。
For this reason, when the
Thus, when the irradiation position 21 on the fabric surface moves, the total length of the path of the laser beam 11 from the
液体は、その付着箇所での液体のピックアップ率が70〜170%、概して110〜140%になるように布帛に付与する。
布帛表面に付着する液体としては水が推奨される。
その水に配合する溶解性を示す親水性物質としては、ポリリン酸アンモニウム、スルフアミン酸アンモニウム、スルフアミン酸グアニジン等の難燃効果を発揮する物質、および、デンプン、ポリビニルアルコール、カルボキシルメチールセルロースナトリウム塩(CMC)等の糊剤が好適に使用される。
水に配合する分散性を示す親水性物質としては、界面活性剤を含むラテックスやエマルジョン樹脂が使用される。
水に配合する吸着性を示す親水性物質としては、ベントナイト、カオリン、クレー等の粘土質鉱物が使用される。
これらの親水性物質の、水への配合量は、それによって水が粘性を僅かに帯びる程度に極く僅かであってよい。
しかし、布帛に付与する液体として水を適用する場合、その水を親水性物質との混合組成物として適用しなければならないと言うことを意味するものではなく、寧ろ、親水性物質との混合組成物としてではなく、水だけを液体として布帛に適用することが望ましい。それは、本発明の実施後に親水性物質を排除する後処理の手間を省くためでもある。
親水性物質を適用して液体の粘度を調整することは、液体を布帛表面に部分的に付着させる場合に有効である。
The liquid is applied to the fabric so that the liquid pick-up rate at the attachment site is 70 to 170%, generally 110 to 140%.
Water is recommended as the liquid adhering to the fabric surface.
Examples of hydrophilic substances that are soluble in water include substances that exhibit a flame-retardant effect such as ammonium polyphosphate, ammonium sulfamate, guanidine sulfamate, and starch, polyvinyl alcohol, sodium carboxymethyl cellulose ( CMC) or the like is preferably used.
As a hydrophilic substance exhibiting dispersibility to be blended in water, latex or emulsion resin containing a surfactant is used.
As the hydrophilic substance showing the adsorptivity to be mixed with water, clayey minerals such as bentonite, kaolin and clay are used.
The amount of these hydrophilic substances incorporated in water may be so small that the water is only slightly viscous.
However, when water is applied as a liquid to be applied to the fabric, it does not mean that the water must be applied as a mixed composition with a hydrophilic substance, but rather a mixed composition with a hydrophilic substance. It is desirable to apply only water as a liquid to the fabric, not as a product. This is also to save the work of post-treatment for eliminating the hydrophilic substance after the practice of the present invention.
Applying a hydrophilic substance to adjust the viscosity of the liquid is effective when the liquid is partially adhered to the fabric surface.
液体を布帛表面に部分的に付着させるためには、捺染糊の印捺に使用される捺染スクリーン、グラビアロール、スプレー等を使用すればよい。
その場合、捺染スクリーン、グラビアロール、スプレー等によって、液体の付着量を部分的に変え、或いは、液体の付着量をなだらかに変え、そうすることによってレーザー光線による熱可塑性繊維の溶融の程度を部分的に変え、或いは、なだらかに変化させ、例えば、熱可塑性繊維が溶融して生じる溝の深さを変えたりなだらかに変化させて、凹凸や起伏が変化した図柄を布帛に描出することも可能になる。
In order to partially adhere the liquid to the surface of the fabric, a printing screen, gravure roll, spray, or the like used for printing the printing paste may be used.
In that case, the amount of liquid adhesion can be changed partially by a printing screen, gravure roll, spray, etc., or the amount of liquid adhesion can be changed gently, so that the degree of melting of the thermoplastic fiber by the laser beam is partially increased. It is also possible to draw a pattern with irregularities and undulations on the fabric by changing the depth of the groove or by gently changing the depth of the groove formed by melting the thermoplastic fiber. .
布帛が、静電植毛布帛、フエルト、起毛布帛、シェニール織物、モケット、別珍、コール天等の織パイル布帛、トリコットやダブルラッシェル等の編パイル布帛等の表面立毛層と裏面基布層との二層構造を成す有毛布帛では、起毛毛羽やパイルによる立毛層の厚みを0.5〜2.5mmにし、レーザー光線の照射時に基布の含有する水分が立毛繊維の先端に移行し易くするとよい。 The fabric is an electrostatic flocking fabric, a felt, a raised fabric, a chenille fabric, a moquette, a beveled fabric, a woven pile fabric such as a corten, a knitted pile fabric such as a tricot or double raschel, etc. In a hairy fabric having a layered structure, it is preferable that the thickness of the raised layer by raised fluff or pile is 0.5 to 2.5 mm, and that moisture contained in the base fabric is easily transferred to the tip of the raised fiber when irradiated with a laser beam.
表面露出繊維の繊度は5dtex以下、好ましくは2dtex以下にする。
熱可塑性繊維としては、ナイロン、ビニロン、ポリプロピレン繊維、アクリル繊維、ポリエステル繊維等が使用される。
布帛表面には、これらの熱可塑性繊維の他に、レーヨン、綿、絹等の非熱可塑性繊維が混在していてもよいが、その場合、非熱可塑性繊維の混用率は30質量%以下にする。
The fineness of the surface exposed fiber is 5 dtex or less, preferably 2 dtex or less.
As the thermoplastic fiber, nylon, vinylon, polypropylene fiber, acrylic fiber, polyester fiber, or the like is used.
In addition to these thermoplastic fibers, non-thermoplastic fibers such as rayon, cotton, and silk may be mixed on the fabric surface. In this case, the mixing ratio of the non-thermoplastic fibers is 30% by mass or less. To do.
起毛布帛やパイル布帛等の有毛布帛は、起毛毛羽やパイルがストライプ状乃至縞状に、或いは市松模様に布帛表面に形成されているものでもよい。 A raised fabric such as a raised fabric or a pile fabric may have a raised fluff or pile formed on the surface of the fabric in a striped or striped pattern or a checkered pattern.

[Comparative example]
A tricot warp knitted pile fabric in which a lattice pattern was drawn was obtained by irradiating the moquette woven in Example 2 in a lattice pattern in the same manner as in Example 2 without immersing it in water.
[効果の確認]
実施例2と比較例において得られたモケットのレーザー光線照射箇所の断面をデジタルマイクロスコープ(キーエンス社製、デジタルHFマイクロスコープVh−8000)で調べ、その照射箇所を観察をした。
[Confirmation of effect]
The cross section of the laser beam irradiated portion of the moquette obtained in Example 2 and the comparative example was examined with a digital microscope (manufactured by Keyence Corporation, Digital HF microscope Vh-8000), and the irradiated portion was observed.
実施例2のモケット23aの照射箇所は、図2に示すように、モケットの地組織28に達する程度に深い2000μm(2mm)前後の深さの概してV字形断面の溝25aを形成している。
そのパイル繊維の溶融塊26aは、図2に円で囲んで拡大して図示するように、そのV字形断面の溝25aの傾斜した溝壁面19に最大寸法200μm以下の顆粒状溶融物となって固着しており、その顆粒状溶融物は、パイル毎に纏まっており、溝25aの深さ方向(パイルの長さ方向)に細かく点在し、レーザー光線の走査方向に帯状にも線状にも連続しているとは認められなかった。
その溝25aの部分を指先で触ると、硬い異物に触れたかの如き感触は感じられなかった。
As shown in FIG. 2, the irradiation place of the moquette 23a of the second embodiment forms a groove 25a having a generally V-shaped cross section having a depth of about 2000 μm (2 mm) deep enough to reach the ground structure 28 of the moquette.
The
When the part of the groove 25a was touched with a fingertip, a touch as if a hard foreign object had been touched was not felt.
比較例のモケット23bの照射箇所は、図3に示すように、パイル繊維24が溶融してパイル面30の下に沈み、パイル繊維の溶融塊26bが底部に溜まって概して平板な断面形状の溝底面27を形成し、深さが400μm(0.4mm)前後の概してコ字形断面の溝25bを形成している。
そのパイル繊維の溶融塊26bは、図3に円で囲んで拡大して図示するように、レーザー光線の走査方向に50μm(0.05mm)前後の隙間を間におき、平板な断面形状を成す長さが1000μm(1.00mm)前後の帯状溶融物となり、レーザー光線のビーム径(0.5mm)に応じた幅の溝底面27を形成し、レーザー光線の走査方向に線状に連続している。
その溝25bの部分を指先で触ると、硬い線状の異物に触れたような確かな感触が感じられた。
As shown in FIG. 3, the irradiated portion of the moquette 23b of the comparative example is a groove having a generally flat cross-sectional shape in which the
The pile fiber melt mass 26b has a flat cross-sectional shape with a gap of about 50 μm (0.05 mm) in the laser beam scanning direction as shown in FIG. Becomes a belt-like melt of about 1000 μm (1.00 mm), and forms a groove bottom surface 27 having a width corresponding to the beam diameter (0.5 mm) of the laser beam and continues linearly in the scanning direction of the laser beam.
When the part of the groove 25b was touched with a fingertip, a certain touch as if touching a hard linear foreign object was felt.
本発明の実施例と比較例における溝25a・25bの形態の差異について考察するに、燈したローソクから水面に垂れ落ちる蝋が水に触れて固まるように、実施例におけるパイル繊維24の溶融物(26a)は、パイル繊維に付着している液体に触れ、顆粒状に固まって左右向き合う溝壁面29a、29bに分かれて固着し、そのように溶融物が向き合う左右の溝壁面29a、29bへと分離し、その左右の溝壁面29a、29bの間の部分に介在しないので、レーザー光線が溶融物(26a)に遮られることなくパイル層31に奥深く入り込み、その結果、地組織28に達する程度の深いV字形溝25aが形成されるものと考えられる。
一方、比較例では、パイル繊維の溶融物(26b)が、パイル繊維24によって格別冷却されることはなく、パイル面に垂れ落ちた蝋が平板な形状を成して固着するように、パイル面30に断面が概して平板な帯状を成して固着し、それがレーザー光線を遮るので、レーザー光線がパイル層31に奥深く入り込まず、溝底27bが平板な浅いコ字形溝25bが形成されるものと考えられる。
尚、図2と図3に円で囲んで拡大して図示する溝壁面は、それぞれ実施例2と比較例のモケットの溝壁面の顕微鏡写真を模写したものである。
In considering the difference in the shape of the grooves 25a and 25b in the example of the present invention and the comparative example, the melt of the
