以下、本発明の床材およびその製造方法の一実施の形態について、図面を参照して詳細に説明する。
本発明の製造方法が適用される床材１０は、例えば、繊維質基材層１１と、繊維質基材層１１に塗布・充填された塩化ビニル樹脂ペースト１２により繊維質基材層１１の表面に形成される中間層の塩化ビニル樹脂層１２ａと、繊維質基材層１１の裏面に形成される塩化ビニル樹脂層１２ｂと、塩化ビニル樹脂ペースト１２による塩化ビニル樹脂層１２ａ，１２ｂの表裏面に積層する表面層１３と、裏面層１４と、を有して構成される。
Hereinafter, an embodiment of a flooring material and a method of manufacturing the same according to the present invention will be described in detail with reference to the drawings.
The floor material 10 to which the manufacturing method of the present invention is applied is, for example, a fibrous base material layer 11 and a surface of the fibrous base material layer 11 formed of a vinyl chloride resin paste 12 applied and filled in the fibrous base material layer 11. A vinyl chloride resin layer 12a as an intermediate layer, a vinyl chloride resin layer 12b formed on the back surface of the fibrous base material layer 11, and a front and back surface of the vinyl chloride resin layers 12a and 12b of the vinyl chloride resin paste 12. It has a surface layer 13 and a back layer 14 to be laminated.
繊維質基材層１１は、ガラス繊維を含む不織布、ガラス繊維を含む織布が用いられる。繊維質基材層１１は、ガラス繊維のみで構成される場合のほか、ガラス繊維に、パルプ等の天然繊維、有機繊維、合成樹脂繊維、金属繊維等の他の繊維を含んで構成される。
繊維質基材層１１は、坪量が５０〜１２０ｇ／ｍ２とされ、通気性を備えている。坪量が５００ｇ／ｍ２未満では、床材１０の強度不足となり、床材１０として必要な寸法安定性を確保することができない。坪量が１２０ｇ／ｍ２を超えると、寸法安定性を確保することができるものの、表面の一部を中間層１２ａとする塩化ビニル樹脂ペースト１２を繊維質基材層１１の内部まで充填することができなくなり、例えば繊維質基材層１１の表面側から充填した塩化ビニル樹脂ペースト１２が裏面側に染み出さず、裏面に塩化ビニル樹脂層１２ｂが存在しない状態となる。これにより、第３の工程Ｃにおける繊維質基材層１１の裏面での裏面層１４との接着性を確保することができなくなる。
As the fibrous base material layer 11, a nonwoven fabric containing glass fiber or a woven fabric containing glass fiber is used. In addition to the case where the fibrous base material layer 11 is made of only glass fibers, the fibrous base material layer 11 is made of glass fibers containing natural fibers such as pulp, organic fibers, synthetic resin fibers, and other fibers such as metal fibers.
The fibrous base material layer 11 has a basis weight of 50 to 120 g / m 2 and has air permeability. If the basis weight is less than 500 g / m 2 , the strength of the flooring material 10 will be insufficient, and the dimensional stability required for the flooring material 10 cannot be secured. When the basis weight exceeds 120 g / m 2 , although dimensional stability can be ensured, the inside of the fibrous base material layer 11 is filled with the vinyl chloride resin paste 12 having a part of the surface as the intermediate layer 12 a. For example, the vinyl chloride resin paste 12 filled from the front side of the fibrous base material layer 11 does not exude to the back side, and the vinyl chloride resin layer 12b does not exist on the back side. This makes it impossible to ensure the adhesiveness of the back surface of the fibrous base material layer 11 to the back surface layer 14 in the third step C.
塩化ビニル樹脂ペースト１２は、繊維質基材層１１に、例えば一部を表面に残して中間層１２ａとしつつ表面から反対面の裏面まで染み出すように塗布・充填される。すなわち、中間層１２ａは、繊維質基材層１１に塗布・充填される塩化ビニル樹脂ペースト１２の一部を表面に残して形成される塩化ビニル樹脂層であり、繊維質基材層１１の表面に一定の厚さで形成されて存在する塩化ビニル樹脂層ということができる。
塩化ビニル樹脂ペースト１２は、塩化ビニル樹脂成分と、可塑剤、充填剤を含んで構成される。塩化ビニル樹脂成分は、懸濁重合により得られる数平均粒子径が８０〜１２０μｍの第１の塩化ビニル樹脂原料２０〜５０質量部と、乳化重合あるいはそれにかわる重合で得られる数平均粒子径が０．０５〜１５μｍの第２の塩化ビニル樹脂原料８０〜５０質量部とからなる１００質量部の塩化ビニル樹脂ペースト１２で構成される。すなわち、繊維質基材層１１に塩化ビニル樹脂ペースト１２を塗布・充填する場合、第２の塩化ビニル樹脂原料のように数平均粒子径が小さい０．０５〜１５μｍのものだけとすると、図３（ａ）に示すように、繊維質基材層１１の表面付近で小さな粒子１２ｃが目詰まりを起こし、繊維質基材層１１の内部まで充填することができない。そこで、第１の塩化ビニル樹脂原料として数平均粒子径が大きい１００μｍ程度のものを配合し、粒子径の大きな粒子１２ｄによって隙間を形成し、図３（ｂ）に示すように、大きな粒子１２ｄと小さな粒子１２ｃの隙間から塩化ビニル樹脂ペースト１２を表面側に一部を残して中間層１２ａとしつつ繊維質基材層１１の内部まで充填させ、裏面まで染み出させるようにしている。
The vinyl chloride resin paste 12 is applied and filled in the fibrous base material layer 11 so as to exude from the front surface to the back surface on the opposite side, for example, while leaving a part on the surface to form the intermediate layer 12a. That is, the intermediate layer 12 a is a vinyl chloride resin layer formed by leaving a part of the vinyl chloride resin paste 12 applied and filled in the fibrous base material layer 11 on the surface. Can be said to be a vinyl chloride resin layer which is formed with a certain thickness.
The vinyl chloride resin paste 12 includes a vinyl chloride resin component, a plasticizer, and a filler. The vinyl chloride resin component is composed of 20 to 50 parts by mass of a first vinyl chloride resin raw material having a number average particle size of 80 to 120 μm obtained by suspension polymerization and a number average particle size of 0 to 50 obtained by emulsion polymerization or a polymerization alternative thereto. And 100 to 50 parts by mass of a second vinyl chloride resin raw material having a thickness of 0.05 to 15 μm. That is, when the vinyl chloride resin paste 12 is applied and filled in the fibrous base material layer 11, if only the material having a small number average particle diameter of 0.05 to 15 μm like the second vinyl chloride resin raw material is used, as shown in FIG. As shown in (a), small particles 12c are clogged in the vicinity of the surface of the fibrous base material layer 11 and cannot be filled inside the fibrous base material layer 11. Therefore, as the first vinyl chloride resin raw material, one having a large number average particle diameter of about 100 μm is mixed, and a gap is formed by the large particle diameter 12d, and as shown in FIG. The vinyl chloride resin paste 12 is filled into the interior of the fibrous base material layer 11 while leaving the intermediate layer 12a, leaving a part of the paste on the surface side, through the gaps between the small particles 12c, so as to exude to the back surface.
第１の塩化ビニル樹脂原料は、いわゆる汎用されている塩化ビニル樹脂原料であるサスペンション塩化ビニル樹脂であり、懸濁重合で製造されたもので、数平均粒子径が８０〜１２０μｍのものである。第１の塩化ビニル樹脂原料は、塩化ビニル樹脂ペースト１２を１００質量部とすると、これに対して２０〜５０質量部配合される。第１の塩化ビニル樹脂原料であるサスペンション塩化ビニル樹脂原料が２０質量部未満であると、十分な隙間を形成して塩化ビニル樹脂ペースト１２を繊維質基材層１１に充填することができない。一方、第１の塩化ビニル樹脂原料であるサスペンション塩化ビニル樹脂原料が５０質量部を超えると、ペースト状にすることが難しくなる場合があり、塩化ビニル樹脂ペースト１２によるペースト加工の加工性が劣り、加工困難となる場合を生じる。 The first vinyl chloride resin raw material is a suspension vinyl chloride resin which is a so-called widely used vinyl chloride resin raw material, which is produced by suspension polymerization and has a number average particle diameter of 80 to 120 μm. The first vinyl chloride resin raw material is added in an amount of 20 to 50 parts by mass based on 100 parts by mass of the vinyl chloride resin paste 12. If the amount of the suspension vinyl chloride resin material as the first vinyl chloride resin material is less than 20 parts by mass, a sufficient gap is formed, and the fibrous base material layer 11 cannot be filled with the vinyl chloride resin paste 12. On the other hand, if the amount of the suspension vinyl chloride resin raw material, which is the first vinyl chloride resin raw material, exceeds 50 parts by mass, it may be difficult to form a paste, and the workability of the paste processing using the vinyl chloride resin paste 12 is poor, In some cases, processing becomes difficult.
第２の塩化ビニル樹脂原料は、数平均粒子径が小さい、いわゆるペースト塩化ビニル樹脂原料であり、乳化重合あるいはそれにかわる重合で得られる数平均粒子径が０．０５〜１５μｍの球状の塩化ビニル樹脂原料である。第２の塩化ビニル樹脂原料は、塩化ビニル樹脂ペースト１２を１００質量部とすると、これに対して８０〜５０質量部配合される。このような数平均粒子径が０．０５〜１５μｍの第２の塩化ビニル樹脂原料を塩化ビニル樹脂ペースト１２に８０〜５０質量部配合することにより、繊維質基材層１１の表面側に一部を残して中間層１２ａとしつつ表面側から内部まで、さらに裏面側まで染み出すように塩化ビニル樹脂ペースト１２を塗布・充填することができる。 The second vinyl chloride resin raw material is a so-called paste vinyl chloride resin raw material having a small number average particle diameter, and a spherical vinyl chloride resin having a number average particle diameter of 0.05 to 15 μm obtained by emulsion polymerization or alternative polymerization. Raw material. Assuming that the vinyl chloride resin paste 12 is 100 parts by mass, the second vinyl chloride resin raw material is blended in an amount of 80 to 50 parts by mass. By blending 80 to 50 parts by mass of the second vinyl chloride resin raw material having such a number average particle diameter of 0.05 to 15 μm with the vinyl chloride resin paste 12, a part of the surface of the fibrous base material layer 11 is formed. The vinyl chloride resin paste 12 can be applied and filled so as to exude from the front side to the inside and further to the back side while forming the intermediate layer 12a while leaving the intermediate layer 12a.
塩化ビニル樹脂ペースト１２は、繊維質基材層１１に対して５００ｇ／ｍ２以上、好ましくは、７６０ｇ／ｍ２以上、さらに好ましくは９７０ｇ／ｍ２以上繊維質基材層１１の表面に塗布される。 The vinyl chloride resin paste 12 is applied to the surface of the fibrous base material layer 11 by 500 g / m 2 or more, preferably 760 g / m 2 or more, more preferably 970 g / m 2 or more. You.

充填材は、特に限定するものではなく、例えば、炭酸カルシウム、酸化カルシウム、炭酸バリウム、水酸化マグネシウム、水酸化アルミニウム、クレー、タルク、マイカ等を用いることができる。
The plasticizer is not particularly limited. For example, phthalic acid-based plasticizers such as dioctyl phthalate (DOP), diisononyl phthalate (DINP), dibutyl phthalate (DBP), and butyl octyl phthalate (BOP), and diisononyl adipate ( An adipic acid plasticizer such as DINA) can be used.
The filler is not particularly limited, and for example, calcium carbonate, calcium oxide, barium carbonate, magnesium hydroxide, aluminum hydroxide, clay, talc, mica and the like can be used.
表面層１３は、繊維質基材層１１の表側の塩化ビニル樹脂層（中間層）１２ａの表面に設けられる。表面層１３は、繊維質基材層１１の表面の加熱ゲル化して形成された塩化ビニル樹脂層１２ａの表面に設ける印刷意匠を施した印刷層１３ａ、耐摩耗性を確保するための透明塩化ビニル樹脂層１３ｂ、必要に応じて形成されるＵＶ塗料層や熱硬化塗料等の表面処理液を塗布した表面処理層等で構成される。なお、印刷層１３ａは、塩化ビニル樹脂層１２ａの表面を平滑にした後、この塩化ビニル樹脂層の表面に印刷層１３ａを形成するようにしても良い。 The surface layer 13 is provided on the surface of the vinyl chloride resin layer (intermediate layer) 12 a on the front side of the fibrous base material layer 11. The surface layer 13 is a printed layer 13a provided with a printing design provided on the surface of a vinyl chloride resin layer 12a formed by heating and gelling the surface of the fibrous base material layer 11, and transparent vinyl chloride for ensuring abrasion resistance. It is composed of a resin layer 13b, a surface treatment layer formed by applying a surface treatment liquid such as a UV paint layer or a thermosetting paint formed as required. The printing layer 13a may be formed such that after the surface of the vinyl chloride resin layer 12a is smoothed, the printing layer 13a is formed on the surface of the vinyl chloride resin layer.
裏面層１４は、繊維質基材層１１の裏側の塩化ビニル樹脂層１２ｂの表面に設けられる。
裏面層１４は、繊維質基材層１１の裏側の表面の加熱ゲル化して形成された塩化ビニル樹脂層１２ｂの表面に設けられ、塩化ビニル樹脂ペーストを塗布し、加熱固化することで形成した塩化ビニル樹脂層１４ａで構成される。また、予め形成しておいた塩化ビニル樹脂シートを塩化ビニル樹脂層１２ｂに直接加熱圧着して塩化ビニル樹脂層１４ａとしても良く、塩化ビニル樹脂ペースト、例えば、上記の塩化ビニル樹脂ペースト１２とは異なる、いわゆるペースト塩化ビニル樹脂を接着剤として塩化ビニル樹脂層１２ｂに塗布し、塩化ビニル樹脂シートを加熱圧着した塩化ビニル樹脂層１４ａとしても良い。
The back surface layer 14 is provided on the surface of the vinyl chloride resin layer 12 b on the back side of the fibrous base material layer 11.

It is composed of a vinyl resin layer 14a. Alternatively, a pre-formed vinyl chloride resin sheet may be directly heated and pressed to the vinyl chloride resin layer 12b to form the vinyl chloride resin layer 14a, which is different from the vinyl chloride resin paste, for example, the above-mentioned vinyl chloride resin paste 12. A so-called paste vinyl chloride resin may be applied as an adhesive to the vinyl chloride resin layer 12b, and the vinyl chloride resin sheet may be heated and pressed to form the vinyl chloride resin layer 14a.
次に、床材１０の製造方法について、説明する。
床材１０の製造工程の概略は、例えば、図２に示すように、繊維質基材層１１に塩化ビニル樹脂ペースト１２がコーター２０で塗工された後、圧着絞りロール２１で圧着し、繊維質基材層１１の表面に塩化ビニル樹脂ペースト１２の一部で中間層となる塩化ビニル樹脂層１２ａを形成しつつ、繊維質基材層１１の表面側から内部まで、さらに内部から裏面側まで染み出すように塩化ビニル樹脂ペースト１２を塗布・充填する。この後、ヒーターやオーブン等の加熱装置２２によって塩化ビニル樹脂ペースト１２を加熱ゲル化させ、繊維質基材層１１を内部の塩化ビニル樹脂、表面の塩化ビニル樹脂層（中間層）１２ａおよび裏面の塩化ビニル樹脂層１２ｂ（図１（ｃ）参照）によって通気性がない状態とする。次いで、表面層１３および裏面層１４を形成する。
すなわち、本発明の床材の製造方法は、懸濁重合により得られる数平均粒子径が８０〜１２０μｍの第１の塩化ビニル樹脂原料２０〜５０質量部と、乳化重合あるいはそれにかわる重合で得られる数平均粒子径が０．０５〜１５μｍの第２の塩化ビニル樹脂原料８０〜５０質量部とからなる１００質量部の塩化ビニル樹脂ペーストを得る第１の工程Ａと、ガラス繊維を含む坪量が５０〜１２０ｇ／ｍ２の繊維質基材層に、前記塩化ビニル樹脂ペーストを塗布・充填して塩化ビニル樹脂の中間層を形成しつつ、前記繊維質基材層の通気性をなくす第２の工程Ｂと、前記繊維質基材層に塗布・充填した前記塩化ビニル樹脂ペーストを固化・ゲル化させた後、前記中間層の表面および前記繊維質基材層の裏面に塩化ビニル樹脂の表面層および裏面層をそれぞれ積層する第３の工程Ｃと、を有して構成される。
Next, a method of manufacturing the flooring 10 will be described.
The outline of the manufacturing process of the flooring material 10 is, for example, as shown in FIG. 2, after a fibrous base material layer 11 is coated with a vinyl chloride resin paste 12 by a coater 20, the fiber material is pressed by a pressing roll 21, While forming a vinyl chloride resin layer 12a as an intermediate layer with a part of the vinyl chloride resin paste 12 on the surface of the fibrous base material layer 11, from the surface side to the inside of the fibrous base material layer 11, from the inside to the back side The vinyl chloride resin paste 12 is applied and filled so as to exude. Thereafter, the vinyl chloride resin paste 12 is heated and gelled by a heating device 22 such as a heater or an oven. The vinyl chloride resin layer 12b (see FIG. 1 (c)) makes the air-impermeable state. Next, the surface layer 13 and the back surface layer 14 are formed.
That is, the method for producing a flooring material of the present invention is obtained by emulsification polymerization or polymerization instead of 20 to 50 parts by mass of the first vinyl chloride resin raw material having a number average particle diameter of 80 to 120 μm obtained by suspension polymerization. A first step A of obtaining 100 parts by mass of a vinyl chloride resin paste comprising a second vinyl chloride resin raw material having a number average particle size of 0.05 to 15 μm and a mass of 50 to 50 parts by mass; A second step of applying and filling the above-mentioned vinyl chloride resin paste to a fibrous base material layer of 50 to 120 g / m 2 to form an intermediate layer of the vinyl chloride resin and eliminating air permeability of the fibrous base material layer; Step B, and after solidifying and gelling the vinyl chloride resin paste applied and filled in the fibrous base material layer, a surface layer of a vinyl chloride resin is formed on the surface of the intermediate layer and the back surface of the fibrous base material layer. And back layer A third step C of stacking each configured with a.
（第１の工程Ａ）
第１の工程Ａは、塩化ビニル樹脂ペースト１２を得る工程である。
第１の工程Ａは、懸濁重合により得られる数平均粒子径が８０〜１２０μｍの第１の塩化ビニル樹脂原料２０〜５０質量部と、乳化重合あるいはそれにかわる重合で得られる数平均粒子径が０．０５〜１５μｍの第２の塩化ビニル樹脂原料８０〜５０質量部とからなる１００質量部の塩化ビニル樹脂ペーストを得る。すなわち、サスペンション塩化ビニル樹脂原料による数平均粒子径が１００μｍ程度の大きいものと、ペースト塩化ビニル樹脂原料による数平均粒子径が０．０５〜１５μｍの小さい原料を混合して構成される（図３（ｂ）参照）。これにより、粒子径の小さい塩化ビニル樹脂ペースだけでは、繊維質基材層１１の表面付近で目詰まりを起こして内部や裏側まで染み出すように塗布・充填できなくなること（図３（ａ）参照）を回避している。
(First step A)
The first step A is a step of obtaining a vinyl chloride resin paste 12.
In the first step A, the number average particle diameter obtained by suspension polymerization is 20 to 50 parts by mass of the first vinyl chloride resin raw material having a number average particle diameter of 80 to 120 μm, and the number average particle diameter obtained by emulsion polymerization or polymerization instead thereof is 100 parts by mass of a vinyl chloride resin paste comprising 0.05 to 15 μm of the second vinyl chloride resin raw material of 80 to 50 parts by mass is obtained. That is, the suspension vinyl chloride resin raw material having a large number average particle diameter of about 100 μm and the paste vinyl chloride resin raw material having a small number average particle diameter of 0.05 to 15 μm are mixed (FIG. 3 ( b)). As a result, the vinyl chloride resin paste having a small particle diameter alone cannot be applied and filled so as to cause clogging near the surface of the fibrous base material layer 11 and to seep out to the inside and the back side (see FIG. 3A). ).
（第２の工程Ｂ）
第２の工程Ｂは、ガラス繊維を含む坪量が５０〜１２０ｇ／ｍ２の繊維質基材層１１に、塩化ビニル樹脂ペースト１２を塗布・充填して、中間層１２ａを形成するとともに、繊維質基材層１１の通気性をなくす（図１（ｂ）〜（ｃ）参照）。すなわち、図２に示すように、坪量が５０〜１２０ｇ／ｍ２の通気性を有する繊維質基材層１１の片面、例えば表面に塩化ビニル樹脂ペースト１２をコーター２０により塗布し、塩化ビニル樹脂ペースト１２の中間層１２ａを形成し、圧着絞りロール２１によって繊維質基材層１１の塗布面と反対面、例えば裏面まで塩化ビニル樹脂ペースト１２の一部が塩化ビニル樹脂層１２ｂとして染み出すようにする。

The vinyl chloride resin paste 12 applied and filled in the fibrous base material layer 11 is solidified and gelled by a heating device 22 such as a heater or an oven. By the heating and gelling of the vinyl chloride resin paste 12, a vinyl chloride resin layer (intermediate layer) 12a is formed on the surface of the fibrous base material layer 11, and a vinyl chloride resin layer 12b is formed on the back surface of the fibrous base material layer 11, respectively. State.
By providing the vinyl chloride resin layers 12a and 12b on these front and back surfaces, the same material as the vinyl chloride resin constituting the surface layer 13 and the back surface layer 14 is obtained, and good adhesion is achieved by bonding the vinyl chloride resin layers to each other. It can be secured and laminated.
表面層１３は、既に説明したように、繊維質基材層１１の表側（床材１０の表面）の中間層である塩化ビニル樹脂層１２ａの表面に設けられる。表面層１３は、繊維質基材層１１の表面の加熱ゲル化して形成された塩化ビニル樹脂層１２ａの表面に設ける印刷意匠を施した印刷層１３ａ、耐摩耗性を確保するための透明塩化ビニル樹脂層１３ｂ、必要に応じて形成されるＵＶ塗料層や熱硬化塗料等の表面処理液を塗布した表面処理層等で構成される。なお、印刷層１３ａは、塩化ビニル樹脂層１２ａの表面を平滑にした後、この塩化ビニル樹脂層の表面に印刷層１３ａを形成するようにしても良い。 As described above, the surface layer 13 is provided on the surface of the vinyl chloride resin layer 12a, which is an intermediate layer on the front side (the surface of the flooring material 10) of the fibrous base material layer 11. The surface layer 13 is a printed layer 13a provided with a printing design provided on the surface of a vinyl chloride resin layer 12a formed by heating and gelling the surface of the fibrous base material layer 11, and transparent vinyl chloride for ensuring abrasion resistance. It is composed of a resin layer 13b, a surface treatment layer formed by applying a surface treatment liquid such as a UV paint layer or a thermosetting paint formed as required. The printing layer 13a may be formed such that after the surface of the vinyl chloride resin layer 12a is smoothed, the printing layer 13a is formed on the surface of the vinyl chloride resin layer.
裏面層１４は、既に説明したように、繊維質基材層１１の裏側（床材１０の裏面）の塩化ビニル樹脂層１２ｂの表面に設けられる。裏面層１４は、繊維質基材層１１の裏側の表面の加熱ゲル化して形成された塩化ビニル樹脂層１２ｂの表面に設けられ、塩化ビニル樹脂ペーストを塗布し、加熱固化することで形成した塩化ビニル樹脂層１４ａで構成される。また、予め形成しておいた塩化ビニル樹脂シートを塩化ビニル樹脂層１２ｂに直接加熱圧着して塩化ビニル樹脂層１４ａとしても良く、塩化ビニル樹脂ペースト、例えば、上記の塩化ビニル樹脂ペースト１２とは異なる、いわゆるペースト塩化ビニル樹脂を接着剤として塩化ビニル樹脂層１２ｂに塗布し、塩化ビニル樹脂シートを加熱圧着した塩化ビニル樹脂層１４ａとしても良い。
こうして表面層１３および裏面層１４を積層することで床材１０の製造が完了する。

It is composed of a vinyl resin layer 14a. Alternatively, a pre-formed vinyl chloride resin sheet may be directly heated and pressed to the vinyl chloride resin layer 12b to form the vinyl chloride resin layer 14a, which is different from the vinyl chloride resin paste, for example, the above-mentioned vinyl chloride resin paste 12. A so-called paste vinyl chloride resin may be applied as an adhesive to the vinyl chloride resin layer 12b, and the vinyl chloride resin sheet may be heated and pressed to form the vinyl chloride resin layer 14a.

また、塩化ビニル樹脂ペースト１２を、粒子径の小さい塩化ビニル樹脂原料（ペースト原料）だけでなく、粒子径の大きい塩化ビニル樹脂原料（サスペンション原料）を配合するようにしたので、繊維質基材層１１の表面で目詰まりを起こすことなく、塗布・充填することができる。
また、塩化ビニル樹脂ペースト１２が表面側の中間層１２ａ、繊維質基材層１１の内部および裏面側を覆って通気性がない状態とすることで、層間剥離等を生じることなく、表面層１３および裏面層１４を積層することができる。
