Description
【０００１】
【発明の属する技術分野】
本発明は、熱融着繊維を含む不織布からなる広告用ポップ板基材に関する。
【０００２】
【従来の技術】
従来、ポスターを貼る掲示板やＣＤ店に展示している広告用ポップ（ＰＯＰ）板等としては、ポリスチレン発泡体からなるボードやベニヤ板が使用されている。
【０００３】
ポリスチレン発泡体からなるボードは、主に広告用ＰＯＰ板等に多く使用されているものの、リサイクル不可能という問題があり、将来の省資源化に適していない。
【０００４】
次に、ベニヤ板は選挙用ポスターの掲示板として多く使用されているが、木材を原材料としているため、ポリスチレン発泡系ボードと比較して密度が高くなるため、重く持ち運びが困難であるだけでなく、作業時に木材の繊維状部分が皮膚に刺さるなど、取り扱いに不便であった。
【０００５】
なお、最近、不織布を掲示板に使用することが提案されている（特開平７−２４８７３６号公報参照）が、この掲示板は、押しピンや画鋲の差し抜き性が良好なものとするため、繊維縮合体を二層以上積層したものであり、押しピンの跡を目立たないようにするためには、これらの上に更に不織布を積層するとしている。かかる掲示板は、経済的にも、また製造時の作業性にも問題があった。
【０００６】
【発明が解決しようとする課題】
本発明は、一層の不織布からなるものであっても、ポスター等を安定して糊等で貼り付け可能とするボード基材すなわち広告用ポップ板基材を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明では、熱融着繊維を含む不織布で、その少なくとも一方の表層部分を、内層部分より密度が高く、硬くなるようにしたものを使用することにより前記課題を解決した。
【０００８】
なお、この不織布は、物理的及び化学的安定性および廃物処理（再生利用可能性）等の点から、全体にポリエステル系繊維からなるものとするのが好ましく、非熱融着繊維は、通常の中実繊維であってもよいが、少なくとも一部に中空繊維を含むのが、広告用ポップ板基材の剛性等の点から好ましい。
【０００９】
また、熱融着繊維としては、熱処理によって、その表面の一部又は全部が溶融して、他の繊維を強固に融着し、不織布の構造を安定化するものであればよく、通常、数十〜百数十℃の温度で溶融（軟化）する素材からなるものを使用するが、このような素材を繊維の一部に含む複合繊維、特に、共重合ポリエチレンテレフタレートを融着成分として表面に有する芯鞘型の熱溶融繊維を使用するのが好ましい。
【００１０】
かかる本発明のボード基材は、例えば通常のポリエステル系短繊維と熱融着性を有するポリエステル系短繊維を原料とし、これらをカード機を通してウエブとして積層し、クロスレイヤー後に加熱処理を施して不織布（平板状）を作成するという工程において、前記加熱処理ゾーンの出口で、ローラで不織布を圧縮し、片面もしくは両面を平滑化するという方法で製造できる。すなわち、不織布に熱融着繊維が混綿されているため、その不織布表層部分における接着性を高め、該表層部分の密度を、内層部分より高くし、表面を平滑なものとして、ポスター等を糊で貼り付け可能とするのである。
【００１１】
本発明のボード基材は、表層部分の厚さが0.５〜５ｍｍで、表層部分の密度が内層部分の密度の1.２〜１０倍、特に1.３〜３倍程度であるのが好ましい。本発明のボード基材は、表層部分の密度を高めたものであるため、全体の密度が0.０１〜0.３ｇ／ｃｍ3 、特に0.０５〜0.２ｇ／ｃｍ3 というように非常に軽量なものであっても、安定して使用できるものであり、非常に使用し易いものとなる。なお、全体の目付は３００〜２０００ｇ／ｍ2 程度で、全体の厚さは２〜３０ｍｍ程度のものが実用的である。なお、密度の高い表層部分と密度の低い内層部分の厚さの比率は、１：１〜３０程度であるのが好ましい。
【００１２】
かかるボード基材は、一枚の不織布からなるものとして、そのまま広告用ポップ板に使用されることもできるが、木や金属性の枠体に固定されたり、また、表面が板状である他の支持体に積層して使用されてもよい。
【００１３】
【発明の実施の形態】
本発明の実施例を次に示す。なお、実施例において％とあるのは、特に断らない限り、重量％を示す。
実施例１
カネボウ合繊（株）製のポリエチレンテレフタレート（ＰＥＴ）短繊維Ｈ３１０（１４ｄｔｅｘ×５１ｍｍ−中実繊維−）を５０％、熱融着繊維としてユニチカファイバー（株）製の共重合ＰＥＴ短繊維４０８０（2.２ｄｔｅｘ×５１ｍｍ）５０％を開繊、混綿し、カード機、クロスレイヤー処理を行った。引き続き、試料の両面側から１４０〜２００℃加熱処理し、更に加熱処理ゾーン出口にて、ローラで不織布を圧縮し、トータル目付７００ｇ／ｍ２ 、トータル厚さ７ｍｍの不織布片面が平滑状である短繊維不織布を得た。この不織布は、平滑状である表層部分は目付１５０ｇ／ｍ２ 、厚さ１ｍｍ、密度0.１５ｇ／ｃｍ３ であるのに対し、内層部分は目付５５０ｇ／ｍ２ 、厚さ６ｍｍ、密度0.０９ｇ／ｃｍ３ であった（かかる物性は、不織布をローラ処理で平滑化し、硬くなった部分を表層部分として１ｍｍ厚にスライスし、残りの６ｍｍ厚の層を内層部分として測定したものである）。これを１０００ｍｍ×１０００ｍｍにカットした後、ポスター等を貼り付けるための広告用ポップ板基材として使用した。
【００１４】
実施例２
実施例１のカネボウ合繊（株）製のポリエチレンテレフタレート（ＰＥＴ）短繊維Ｈ３１０の代わりに、カネボウ合繊（株）製のポリエチレンテレフタレート（ＰＥＴ）短繊維Ｈ５８８（１４ｄｔｅｘ×５１ｍｍ−中空繊維−）を使用した以外は、実施例１と同様の方法を実施した。
【００１５】
実施例１及び２で得られたいずれのボード基材も、安定してポスター等の糊での貼り付けが可能であった。特に、非熱融着繊維として中空繊維を使用した実施例２のボード基材は、剛性があり、一層の不織布状で、そのまま使用しても広告用ポップ板として利用価値あるものであった。
【００１６】
【発明の効果】
本発明の広告用ポップ板基材は、一層の不織布を基材として使用できるため、製造及び使用いずれの面においても、非常に扱い易い。また、該不織布は、ポリエステル系繊維を主体とするため、リサイクル可能であり、将来の省資源化に適している。更に、非常に軽量で、表面が平滑であるため、外観に優れ、ポスター等を糊で貼り付け易いものとなる。なお、本発明のボード基材は、比較的密度が高く、硬質である表層部分に続いて、繊維が比較的自由に絡み合った内層部分が存在するため、押しピンや画鋲も、その先端が、安定して表層部分を通り、内層部分で保持されるものとなり、着脱が容易でありながら、ポスター等の貼り付けを確実なものとする。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pop board substrate for advertisement made of a nonwoven fabric containing heat-sealing fibers.
[0002]
[Prior art]
Conventionally, boards and veneer boards made of polystyrene foam have been used as bulletin boards for posting posters and advertising pop (POP) boards on display at CD stores.
[0003]
Boards made of polystyrene foam are mainly used for advertising POP boards and the like, but have a problem that they cannot be recycled and are not suitable for future resource saving.
[0004]
Secondly, veneer boards are often used as bulletin boards for posters for elections, but because they are made of wood, the density is higher than polystyrene foam boards, making them not only heavy and difficult to carry, but also work. Occasionally, the fibrous part of the wood pierced the skin and was inconvenient to handle.
[0005]
Recently, it has been proposed to use a nonwoven fabric for a bulletin board (see Japanese Patent Application Laid-Open No. 7-248736). However, this bulletin board has a good fiber-condensation method in order to make it easy to insert and remove push pins and pushpins. Two or more layers of the body are laminated, and in order to make the trace of the push pin inconspicuous, a nonwoven fabric is further laminated thereon. Such a bulletin board has a problem in terms of economy and workability at the time of manufacture.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a board base material, that is, a pop board base material for advertisement, that can stably stick a poster or the like with glue or the like even if it is made of a single layer of nonwoven fabric.
[0007]
[Means for Solving the Problems]
In the present invention, the above-mentioned problems have been solved by using a nonwoven fabric containing heat-sealing fibers, in which at least one surface layer portion has a higher density and hardness than the inner layer portion.
[0008]
This non-woven fabric is preferably made of polyester fiber as a whole from the viewpoints of physical and chemical stability, waste disposal (recyclability), etc. Although it may be a solid fiber, it is preferable that at least a part thereof contains a hollow fiber from the viewpoint of the rigidity of the pop board substrate for advertisement .
[0009]
Further, the heat-sealable fiber is not particularly limited as long as a part or all of its surface is melted by heat treatment, and the other fiber is firmly fused to stabilize the structure of the nonwoven fabric. A material made of a material that melts (softens) at a temperature of 10 to 100 ° C. is used. A composite fiber containing such a material as a part of the fiber, in particular, a copolymerized polyethylene terephthalate is used as a fusion component on the surface. It is preferable to use a core-sheath type hot-melt fiber.
[0010]
Such a board substrate of the present invention is made of, for example, a normal polyester-based short fiber and a polyester-based short fiber having heat-fusibility as a raw material, these are laminated as a web through a card machine, and subjected to a heat treatment after cross-layering to produce a nonwoven fabric. In the step of producing (flat plate shape), it can be produced by a method of compressing the nonwoven fabric with a roller at the outlet of the heat treatment zone and smoothing one side or both sides. That is, since heat-bonding fibers are mixed with the nonwoven fabric, the adhesiveness in the surface layer portion of the nonwoven fabric is increased, the density of the surface layer portion is made higher than that of the inner layer portion, the surface is smooth, and the poster is glued. It can be pasted.
[0011]
In the board substrate of the present invention, the thickness of the surface layer portion is 0.5 to 5 mm, and the density of the surface layer portion is 1.2 to 10 times, particularly about 1.3 to 3 times the density of the inner layer portion. preferable. Since the board base material of the present invention has a higher density of the surface layer portion, the overall density is extremely high , such as 0.01 to 0.3 g / cm 3 , particularly 0.05 to 0.2 g / cm 3. Even if it is very light, it can be used stably and becomes very easy to use. It is practical that the overall basis weight is about 300 to 2000 g / m 2 and the overall thickness is about 2 to 30 mm. In addition, it is preferable that the ratio of the thickness of the high-density surface layer part and the low-density inner layer part is about 1: 1 to 30.
[0012]
Such board substrates, as consisting of a single nonwoven fabric, but can also be used for that or or advertising for pop plate, or fixed to the wood or metal frame body, also, the surface plate It may be used by being laminated on another support.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the present invention will be described below. In the examples, “%” means “% by weight” unless otherwise specified.
Example 1
50% of polyethylene terephthalate (PET) short fiber H310 (14 dtex × 51 mm—solid fiber—) manufactured by Kanebo Synthetic Fiber Co., Ltd. Copolymerized PET short fiber 4080 (2. (2 dtex × 51 mm) 50% was opened and blended, and a card machine and a cross layer treatment were performed. Subsequently, the sample is heated at 140 to 200 ° C. from both sides of the sample, and the nonwoven fabric is compressed with a roller at the exit of the heat treatment zone, and the nonwoven fabric with a total basis weight of 700 g / m 2 and a total thickness of 7 mm is smooth. A fiber nonwoven fabric was obtained. In this nonwoven fabric, the smooth surface layer portion has a basis weight of 150 g / m 2 , a thickness of 1 mm, and a density of 0.15 g / cm 3 , whereas the inner layer portion has a basis weight of 550 g / m 2 , a thickness of 6 mm, and a density of 0. 09g / cm was 3 (such physical properties, a nonwoven fabric is smoothed by the roller process, slicing the hardened portion 1mm thick as a surface layer portion is obtained by measuring the layer of remaining 6mm thick as the inner layer portion) . After this was cut into 1000 mm × 1000 mm, it was used as a pop board substrate for advertisement for attaching a poster or the like.
[0014]
Example 2
In place of the polyethylene terephthalate (PET) short fiber H310 manufactured by Kanebo Synthetic Co., Ltd. in Example 1, polyethylene terephthalate (PET) short fiber H588 (14 dtex × 51 mm-hollow fiber-) manufactured by Kanebo Synthetic Co., Ltd. was used. Except for this, the same method as in Example 1 was performed.
[0015]
Any of the board substrates obtained in Examples 1 and 2 could be stably pasted with glue such as a poster. In particular, the board substrate of Example 2 in which hollow fibers were used as non-heat-bonding fibers had rigidity, a single layer of nonwoven fabric, and was useful as an advertising pop board even if used as it was.
[0016]
【The invention's effect】
Since the pop board substrate for advertisement of the present invention can use a single layer of nonwoven fabric as a substrate, it is very easy to handle in both production and use. Moreover, since the nonwoven fabric is mainly made of polyester fibers, it can be recycled and is suitable for future resource saving. Furthermore, since it is very light and has a smooth surface, it is excellent in appearance and can easily stick a poster or the like with glue. In addition, since the board base material of the present invention has an inner layer portion in which fibers are relatively intertwined following a surface layer portion that is relatively high in density and is hard, the tip of a push pin or a thumbtack is also It passes stably through the surface layer part and is held by the inner layer part, and it is easy to attach and detach, but ensures the attachment of a poster or the like.
