【発明の属する技術分野】
本発明は、肌身に触れて使用される下敷材、即ち、出入口に敷かれるダストコントロールマット、浴室内外に敷かれるバス(湯上がり)マット、寝台に敷かれるベットマット、寝台の中芯に敷かれるベットパット(芯地)、トイレの内外に敷かれるトイレマット、台所・厨房に敷かれるキッチンマット、車内に敷かれるカーマット等として使用されるマットに関するものである。
【0002】
【従来の技術】
靴裏や足裏の泥や塵埃(以下、塵埃等と言う。)や汗や水気(以下、水気等と言う。)を拭き取るマットしては、通常タフテッドカーペットやウイルトンカーペット、タオル等のパイル布帛が使用されている。
パイル布帛に成るマットでは、表面が繊維毛羽で構成されており、塵埃や水気等はパイル毛羽の間に突き刺さるように、或いは、吸着するようにして拭き取られる。
【0003】
【発明が解決しようとする課題】
しかし、長期継続使用によってパイル毛羽はへたり、パイル毛羽とパイル毛羽とが密着してその間に塵埃が入り込み難くなり、そのパイル毛羽間に入り込まずに表面に付着しただけの塵埃等は二次汚染の元となり、又、マット内部に吸収された水気が毛細管現象によって表面に漂い、その水気がベトツキ感や蒸れ感を与える。特に、ベットマットでは、パイル毛羽の保温断熱作用によってマット表面から受けるベトツキ感や蒸れ感は著しく、その継続使用は耐え難く、皮膚障害の元にもなる。
【0004】
そこで、パイル層の繊維間の隙間を粗くして通気性をよくし、繊維間の湿気が溜まらないようにするため、パイル繊維に円形断面を有し、太く剛直な50デニール以上のポリエステル繊維モノフイラメントを使用し、そのパイル繊維の単糸繊度を太くした分だけパイル繊維の数を少なくしてパイル層の繊維間の隙間を粗くすることを試みた。しかし、単糸繊度が50デニールを越えるポリエステル繊維モノフイラメントは、釣糸に使用し得るものであって弾撥力が強く、それを数本合撚してパイル糸を調製しようとしても、捩れた状態でセットさせることは出来ず、又、それを数本引き揃えてループパイルを形成しようとしても、バックステッチもループパイルと同様に円形になって基布の裏面に***し、バックステッチをバッキング剤によって基布に接着固定し難く、ループパイルが不安定で、そのループパイルのマット(パイル布帛)を製造することは極めて困難であることが分かった。
【0005】
【発明の目的】
そこで本発明は、何らかの方法によって50デニールを越える太いポリエステル繊維モノフイラメントのループパイルを基布に安定に形成し、長期継続使用してベトツキ感や蒸れ感を与えず、そして皮膚障害を惹起せず、塵埃や水気の拭き取り効果が高く、而も、パイル布帛と同等またはそれ以上の弾性のあるマットを提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明に係るマット24は、上下に重なる上布18と下布19の間がそれぞれ上端が上布18に下端が下布19に係止された連結糸17によって一定間隔に保たれた二重経編布帛20の下布19の裏面に防水性裏材22が積層されていることを第1の特徴とする。
【0007】
本発明に係るマット24は、上下に重なる上布18と下布19の間がそれぞれ上端が上布18に下端が下布19に係止された連結糸17によって一定間隔に保たれており、上布18が鎖編目列11に囲まれた開口16を有するネット構造を形成しており、下布19の鎖編目列間12・12が挿入糸13に連結されている二重経編布帛20の下布19の裏面に防水性裏材22が積層されていることを第2の特徴とする。
【0011】
本発明に係るマット24の第6の特徴は、上記第1、第2、第3、第4および第5の何れかの特徴に加えて、連結糸17が単糸繊度50デニール以上のポリエステル繊維、ポリアミド繊維、ポリプロピレン繊維、ポリエチレン繊維等の合成繊維フイラメント糸であり、連結糸17の上端が上布18の表面に露出していることにある。
【0012】
本発明に係るマット24の第7の特徴は、上記第2、第3、第4、第5および第6の何れかの特徴に加えて、上布の鎖編目列11が、数コース毎に1ウェール分づつ左右に移動し、左右隣合う2本の上布地経糸が合体した複合鎖編目14と、各上布地経糸が単独で形成する単一鎖編目15とが交互に続くものであり、上布の開口16が複合鎖編目14と単一鎖編目15に囲まれて形成され、その複合鎖編目14を頂点とし、下布の挿入糸13を底辺とし、複合鎖編目14から左右の下布鎖編目列12・12へと分かれて続く2本の連結糸24a・24bを斜辺とする三角形状のスペース23が、複合鎖編目14の下側に形成されていることにある。
【0013】
【発明の実施の形態】
図1は、ダブルラッシェル経編機によって編成されたマット24を図示し、11は上布地経糸が形成する鎖編目列、12は下布地経糸が形成する鎖編目列、13は下布鎖編目列間を連結する挿入糸、17は連結糸である。下布鎖編目列12はウェール方向(下布の長さ方向)に真っ直ぐに連続し、その各鎖編目のループの中を挿入糸13が潜り抜けて下布鎖編目列間12・12を連結して下布19が編成される。
【0014】
上布鎖編目列11では、数コース毎(上布の長さ方向に続く編目)に1ウェール分(経編機の隣合うニードルとニードルとの距離)づつ左右に移動し、その左右隣合う2本の上布地経糸が合体して形成する複合鎖編目14と、その移動する1コースまたは数コースにおいて各上布地経糸が単独で形成する単一鎖編目15が交互に続いており、複合鎖編目14と単一鎖編目15とによって上布18が亀甲紗状に編成され、複合鎖編目14と単一鎖編目15とによるネット状の開口16が上布18に形成されている。連結糸17の上端と下端は、それぞれ上布地編糸と下布地編糸と一体になって鎖編目ループ(11・12)を形成し、上布18と下布19を連結している。
【0015】
このため、連結糸17の下端は下布鎖編目列12と同様にウェール方向に真っ直ぐに連続するが、連結糸17の上端は上布鎖編目列11と同様に数コース毎に1ウェール分だけ左右に変動し、複合鎖編目14の形成される箇所では、連結糸17a・17bは複合鎖編目14から左右の下布鎖編目列12へと傾斜して続き、その結果、上布の複合鎖編目14の下側には、複合鎖編目14を頂点とし、挿入糸13を底辺とし、複合鎖編目14から左右の下布鎖編目列12へと分かれて続く連結糸17a・17bを斜辺とする三角形状のスペース23がウェール方向に数コース毎に形成されることになる。
【0016】
連結糸17の上端が上布18の表面に露出するようにするには、上布地経糸よりも太くスベスベした単糸繊度が50〜500デニールの非扁平断面(扁平率が2未満で実質的に円形断面)のポリエステル繊維、ポリアミド繊維、ポリプロピレン繊維、ポリエチレン繊維等の合成繊維フイラメントを1本または数本引き揃えて連結糸17に使用するとよい。
【0017】
防水性裏材22は、下布19の裏面に塩化ビニルペースト組成物やラテックスその他の樹脂組成物を塗布し、或いは、接着剤を介して合成樹脂製シートを下布19の裏面に貼り合わせ、或いは、合成樹脂製シートを下布19の裏面に加熱融着させ、或いは又、合成樹脂組成物を加熱溶融させて下布19の裏面に塗布積層する。
【0018】
【発明の効果】
本発明によると、マット本体を構成する二重経編布帛20は、上布18と下布19の間で連結糸17をセンターカットして人工芝生を造る中間製品とも言えるものであるから強い弾性を有する。そのマット24に弾性をもたらす連結糸17の上端が上布18に係止され、その上布18が連結糸17の隣合う上端相互間を連結しているので、下布19から突き出ている連結糸17が強い弾性を発揮し、而も、連結糸17が、カットパイル構造ではなく、上端がループパイルの先端と同様にU字状に折れ曲がって下布19へと続く輪奈構造を成すので、その弾性はループパイルと同様に優れたものとなる。
【0019】
又、連結糸17は、そのようにループパイルと同様に輪奈構造を成すだけではなく、その上端と下端が上布18と下布19に係止されているので、その輪奈構造が安定する。その結果、連結糸17に単糸繊度が50デニール以上の円形断面のポリエステル繊維フイラメント糸を使用する場合でも、連結糸17の上端や下端が上布や下布の外側に不規則に突き出ることがなく、それ故に、表面が平滑でスベスベした単糸繊度が100デニール以上の太く剛直な円形断面のポリエステル繊維フイラメント糸を連結糸17に使用することも出来、その上端が上布18の表面に露出していてもマット24の表面が平滑でチクチクした刺激を与えず、長く肌身を触れて使用する場合でも皮膚障害を惹起しない。
【0020】
そして、マット24の裏面には防水性裏材22が積層されているので、表面(18)から入り込んだ水気等が裏面(14)を透過せず、マット24は、乳幼児用や介護老人用のベットパッド(中芯)やベットマットに適したものとなる。
【0021】
又、マット24が上布18と下布19の二重構造を成し、その上布18に開口16が形成されているので、塵埃等は上布18に拭き取られて開口16に落ちて溜まり、それが開口16から出て靴裏等に再付着することがなく、その開口16に汚水が溜まっても裏材22に止められて床面等に滲み出すことがない。そして、開口16が連結糸17に支えられて下布19から***した紐状鎖編目列12(14・15)で縁取られ、その紐状鎖編目列12がマット表面を形成する上布18を構成しているので、塵埃等が確実に拭き取られる。
【0022】
その場合、そのマット周囲裏材22から***した枠材21で縁取れば、開口16に溜まった水気等が枠材21に堰止められて外部に流れ出ることがない。
【0025】
マット表面ポリエステル繊維、ポリアミド繊維、ポリプロピレン繊維、ポリエチレン繊維等の釣糸のように太く非吸湿性か極低吸湿性のフイラメント糸(17)で構成したものでは、開口等に汚水が溜まっても湿気や蒸れ感を与えず、而も、連結糸17の上端がループパイルの如く折れ曲がって下布19へと続き、また、上布18によって隣合う連結糸17の上端と上端の間が連結されているのでマット表面はなめらかなものとなる。
【0026】
そして、連結糸17は、従来のパイル布帛のパイル糸に使用されていた単糸繊度が2〜5デニールのパイル毛羽ではなく、単糸繊度が50デニール以上で太く剛直でブラシのようなものであるから、連結糸17の目付を従来のパイル布帛のパイル目付と同じにしても、単糸繊度を太くした分だけ連結糸間17・17の隙間を従来のパイル布帛のパイル繊維間の隙間よりも粗くすることが出来、上布18と下布19の間に塵埃等や水気等が溜まり易く、又、連結糸間17・17の隙間を従来のパイル布帛のパイル繊維間の隙間よりも粗くすることが出来るので、上布18と下布19の間に溜まった塵埃等や水気等が洗浄除去し易くなる。
【0027】
そして本発明によると、上布の鎖編目列11が、数コース毎に1ウェール分づつ左右に移動し、左右隣合う2本の上布地経糸が合体した複合鎖編目14と、各上布地経糸が単独で形成する単一鎖編目15とが交互に続くものであり、上布の開口16が複合鎖編目14と単一鎖編目15に囲まれて形成され、その複合鎖編目14を頂点とし、下布の挿入糸13を底辺とし、複合鎖編目14から左右の下布鎖編目列12・12へと分かれて続く2本の連結糸17a・17bを斜辺とする三角形状のスペース23が複合鎖編目14の下側に形成されており、単に、連結糸17に太く剛直なフイラメント糸が使用されているとか、連結糸17がループパイルと同様に輪奈構造を成すと言う理由だけではなく、三角形状をなすスペース23の2辺を構成する2本の連結糸17a・17bによって上布18が支えられているので、マット24は極めて弾性に富むものとなる。
【0028】
このように本発明に係るマット24は、肌身に触れて使われ、水気を帯び易いバスマット、乳幼児用や介護老人用ベットシート(ベットパットやベット芯地)、トイレ(特に公衆便所)マット、キッチン(台所・厨房)マット、その他の肌身に触れて使用されるダストコントロールマットやカーマット等の下敷材に頗る好都合である。

BACKGROUND OF THE INVENTION
The present invention relates to an underlay material used in contact with the skin, that is, a dust control mat laid at the entrance, a bath (bath) mat laid inside and outside the bathroom, a bed mat laid on the bed, and a bed pad laid on the center of the bed The present invention relates to a mat used as (interlining), a toilet mat laid inside and outside a toilet, a kitchen mat laid in a kitchen / kitchen, a car mat laid in a vehicle, and the like.
[0002]
[Prior art]
Mud and dust (hereinafter referred to as dust etc.), sweat and moisture (hereinafter referred to as water etc.) on the soles and soles of the shoes and mats to wipe off usually piles such as tufted carpet, Wilton carpet and towels A fabric is used.
In the mat made of a pile fabric, the surface is composed of fiber fluff, and dust, water, etc. are wiped off so as to pierce or adsorb between the pile fluff.
[0003]
[Problems to be solved by the invention]
However, the pile fluff sags due to continuous use over a long period of time, and the pile fluff and the pile fluff are in close contact with each other, making it difficult for dust to get in between them. Dust that only adheres to the surface without entering between the pile fluff is secondary contamination. Also, the water absorbed inside the mat drifts to the surface by capillary action, and the water gives a sticky feeling and stuffiness. In particular, with a bed mat, the feeling of stickiness and stuffiness received from the surface of the mat due to the heat insulation and heat-insulating action of the pile fluff is remarkable, and its continuous use is unbearable and may cause skin damage.
[0004]
Therefore, in order to improve the air permeability by roughening the gaps between the fibers in the pile layer and preventing the moisture between the fibers from accumulating, the pile fibers have a circular cross section and are thick and rigid polyester fiber monofilaments of 50 denier or more. Using filament, an attempt was made to reduce the number of pile fibers and increase the gap between the fibers in the pile layer by increasing the single yarn fineness of the pile fibers. However, polyester fiber monofilaments with a single yarn fineness of more than 50 denier can be used for fishing lines and have strong resilience. Even if you try to prepare a pile yarn by twisting several of them, the twisted state If you try to form a loop pile by aligning several of them, the back stitch will be rounded like the loop pile and raised on the back of the base fabric, and the back stitch will be backed by the backing agent. Thus, it was found that it was difficult to bond and fix to the base fabric, the loop pile was unstable, and it was extremely difficult to produce a mat (pile fabric) of the loop pile.
[0005]
OBJECT OF THE INVENTION
Therefore, the present invention stably forms a loop pile of a thick polyester fiber monofilament exceeding 50 denier by some method on the base fabric, does not give a sticky feeling or stuffiness, and does not cause skin damage. The object of the present invention is to provide a mat that has a high effect of wiping off dust and water, and has an elasticity equivalent to or higher than that of a pile fabric.
[0006]
[Means for Solving the Problems]
In the mat 24 according to the present invention, the upper cloth 18 and the lower cloth 19 that are overlapped with each other are double-layered by a connecting thread 17 in which the upper end is locked to the upper cloth 18 and the lower end is locked to the lower cloth 19. The first feature is that a waterproof backing 22 is laminated on the back surface of the lower fabric 19 of the warp knitted fabric 20.
[0007]
In the mat 24 according to the present invention, an upper cloth 18 and a lower cloth 19 that are vertically overlapped are maintained at a constant interval by a connecting thread 17 that is engaged with an upper cloth 18 and a lower cloth 19 with a lower end. A double warp knitted fabric 20 in which an upper fabric 18 forms a net structure having an opening 16 surrounded by a chain stitch row 11, and the chain stitch rows 12, 12 of the lower fabric 19 are connected to the insertion yarn 13. A second feature is that a waterproof backing 22 is laminated on the back surface of the lower cloth 19.
[0011]
The sixth feature of the mat 24 according to the present invention is that, in addition to any of the first, second, third, fourth and fifth features, the connecting yarn 17 is a polyester fiber having a single yarn fineness of 50 denier or more. The synthetic fiber filament yarn such as polyamide fiber, polypropylene fiber, polyethylene fiber, etc., and the upper end of the connecting yarn 17 is exposed on the surface of the upper cloth 18.
[0012]
The seventh feature of the mat 24 according to the present invention is that, in addition to any of the second, third, fourth, fifth and sixth features, the chain stitch row 11 of the upper fabric is provided every several courses. It moves to the left and right by 1 wal, and the composite chain stitch 14 in which two upper fabric warps adjacent to the left and right are combined, and the single chain stitch 15 that each upper fabric warp forms independently, The upper fabric opening 16 is formed by being surrounded by the composite chain stitch 14 and the single chain stitch 15, with the composite chain stitch 14 as the apex, the lower fabric insertion thread 13 as the bottom, and the left and right lower sides from the composite chain stitch 14. A triangular space 23 is formed on the lower side of the composite chain stitch 14 with the two connecting yarns 24a and 24b divided into the fabric chain stitch rows 12 and 12 as hypotenuses.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates a mat 24 knitted by a double raschel warp knitting machine, wherein 11 is a chain stitch row formed by upper fabric warp yarns, 12 is a chain stitch row formed by lower fabric warp yarns, and 13 is a lower fabric chain stitch row. An insertion thread 17 for connecting them is a connecting thread. The lower fabric chain stitch row 12 continues straight in the wale direction (the length direction of the lower fabric), and the insertion yarn 13 penetrates through the loop of each chain stitch to connect the lower fabric chain stitch rows 12 and 12 together. Then, the lower cloth 19 is knitted.
[0014]
In the upper fabric chain stitch row 11, it moves left and right by one wal (distance between adjacent needles of the warp knitting machine) every several courses (the stitches that follow the length of the upper fabric), and the left and right sides are adjacent to each other. Composite chain stitches 14 formed by combining two upper fabric warp yarns and single chain stitches 15 formed by each upper fabric warp independently in one or several courses of movement are alternately continued. The upper cloth 18 is knitted in a turtle shell shape by the stitch 14 and the single chain stitch 15, and a net-like opening 16 by the composite chain stitch 14 and the single chain stitch 15 is formed in the upper cloth 18. The upper end and the lower end of the connecting yarn 17 are respectively integrated with the upper fabric knitting yarn and the lower fabric knitting yarn to form a chain stitch loop (11, 12), and the upper fabric 18 and the lower fabric 19 are connected.
[0015]
For this reason, the lower end of the connecting yarn 17 continues straight in the wale direction like the lower fabric chain stitch row 12, but the upper end of the connecting yarn 17 is equivalent to one wale every several courses like the upper fabric chain stitch row 11. At the portion where the composite chain stitch 14 is formed, the connecting yarns 17a and 17b are inclined from the composite chain stitch 14 to the left and right lower fabric chain stitch rows 12, and as a result, the composite chain of the upper fabric is formed. Below the stitch 14, the composite chain stitch 14 is the apex, the insertion yarn 13 is the bottom, and the connecting yarns 17 a and 17 b that are separated from the composite chain stitch 14 to the left and right lower fabric chain stitch rows 12 are the hypotenuse. Triangular spaces 23 are formed every few courses in the wale direction.
[0016]
In order for the upper end of the connecting yarn 17 to be exposed on the surface of the upper fabric 18, the non-flat cross section having a single yarn fineness of 50 to 500 denier that is thicker and smoother than the upper fabric warp (substantially less than 2) A synthetic fiber filament such as a polyester fiber, a polyamide fiber, a polypropylene fiber, or a polyethylene fiber having a circular cross section may be used for the connecting yarn 17 by aligning one or several synthetic fiber filaments.
[0017]
The waterproof backing 22 is formed by applying a vinyl chloride paste composition or a latex or other resin composition to the back surface of the lower cloth 19, or attaching a synthetic resin sheet to the back surface of the lower cloth 19 with an adhesive. Alternatively, a synthetic resin sheet is heated and fused to the back surface of the lower cloth 19, or alternatively, the synthetic resin composition is heated and melted and applied and laminated on the back surface of the lower cloth 19.
[0018]
【The invention's effect】
According to the present invention, the double warp knitted fabric 20 constituting the mat body can be said to be an intermediate product in which an artificial lawn is constructed by center-cutting the connecting yarn 17 between the upper fabric 18 and the lower fabric 19, so that it has strong elasticity. Have The upper end of the connecting thread 17 that provides elasticity to the mat 24 is locked to the upper cloth 18, and the upper cloth 18 connects the upper ends adjacent to each other of the connecting thread 17. Since the thread 17 exhibits strong elasticity, the connecting thread 17 does not have a cut pile structure, but has a wanna structure in which the upper end is bent in a U shape like the tip of the loop pile and continues to the lower cloth 19. The elasticity is as excellent as the loop pile.
[0019]
In addition, the connecting yarn 17 not only has a wrinkle structure like the loop pile, but also has an upper end and a lower end that are locked to the upper cloth 18 and the lower cloth 19, so that the wanna structure is stable. To do. As a result, even when a polyester fiber filament yarn having a circular cross section having a single yarn fineness of 50 denier or more is used as the connecting yarn 17, the upper end and the lower end of the connecting yarn 17 may protrude irregularly outside the upper and lower fabrics. Therefore, it is also possible to use a polyester fiber filament yarn having a thick and rigid circular cross section with a smooth and smooth single yarn fineness of 100 denier or more as the connecting yarn 17, and its upper end exposed on the surface of the upper fabric 18. Even if it is used, the surface of the mat 24 does not give a smooth and tingling irritation, and does not cause skin damage even when the skin is touched for a long time.
[0020]
Further, since the waterproof backing 22 is laminated on the back surface of the mat 24, moisture or the like entering from the front surface (18) does not permeate the back surface (14), and the mat 24 is used for infants and nursing care elderly people. Suitable for bed pads (core) and bed mats.
[0021]
Further, since the mat 24 has a double structure of the upper cloth 18 and the lower cloth 19 and the opening 16 is formed in the upper cloth 18, dust or the like is wiped off by the upper cloth 18 and falls into the opening 16. It collects and does not come out of the opening 16 and reattach to the shoe back or the like, and even if dirty water accumulates in the opening 16, it is stopped by the backing 22 and does not ooze out to the floor surface or the like. The opening 16 is edged by a string-like chain stitch row 12 (14, 15) raised from the lower cloth 19 supported by the connecting thread 17, and the string-like chain stitch row 12 forms the mat surface. Since it comprises, dust etc. are wiped off reliably.
[0022]
In that case, the mat around a frame member 21 that protrudes from the backing 22 edging lever, moisture or the like accumulated on the opening 16 is prevented from flowing to the outside dammed the frame member 21.
[0025]
Matte surface polyester fibers, polyamide fibers, polypropylene fibers, intended configured with thick non-hygroscopic or very low hygroscopicity filament yarn as fishing line, such as polyethylene fibers (17), moisture be accumulated sewage in the opening or the like The upper end of the connecting yarn 17 bends like a loop pile and continues to the lower fabric 19, and the upper fabric 18 connects between the upper end and the upper end of the adjacent connecting yarn 17. As a result, the matte surface is smooth.
[0026]
The connecting yarn 17 is not a pile fluff having a single yarn fineness of 2 to 5 denier, which is used for a pile yarn of a conventional pile fabric, but a single yarn fineness of 50 denier or more and thick, rigid and brush-like. Therefore, even if the basis weight of the connecting yarn 17 is the same as the pile basis weight of the conventional pile fabric, the gap between the connecting yarns 17 and 17 is made larger than the gap between the pile fibers of the conventional pile fabric by the increase in the single yarn fineness. Can be roughened, and dust and water can easily accumulate between the upper cloth 18 and the lower cloth 19, and the gap between the connecting yarns 17 and 17 is coarser than the gap between the pile fibers of the conventional pile cloth. Therefore, dust and water collected between the upper cloth 18 and the lower cloth 19 can be easily cleaned and removed.
[0027]
