Abstract

<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a fibrous roll hardly generating swelling on the outer periphery. <P>SOLUTION: A belt-shaped fiber aggregate 1 double-folded in the longitudinal direction is prepared, and a linear fine line 3 is inserted into the fiber aggregate in the longitudinal direction along the inner side of the folding line 2. After that, the folding line 2 side is sewn into a gather by using a differential sewing machine with the fine line 3 interposed between the folding line 2 and a machine-sewing thread 4 to obtain a gathered fabric 5. The gathered fabric 5 is spirally wound several times so that the folding line 2 of the gathered fabric 5 abuts on the outer peripheral surface of a temporary shaft 7. After that, pressure opposed to pressure plates 8 and 9 is applied to contract the gathered fabric 5 in the axial direction of the temporary shaft 7, and the gathered fabric is heated to be fixed while the contracted state is retained. After that, by removing the pressure plates 8 and 9 and pulling out the temporary shaft 7, a fibrous cylindrical body is obtained. Then, by inserting a roll shaft into the hollow of the fibrous cylindrical body, the fibrous roll is obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、繊維質ロールを製造する際に用いる繊維質円筒体の製造方法に関するものである。   The present invention relates to a method for producing a fibrous cylindrical body used when producing a fibrous roll.

従来より、繊維質ロールは、繊維質円筒体を製造した後、この繊維質円筒体の中空にロール軸を挿入することにより製造されている。繊維質円筒体の製造方法としては、不織布等からなる帯状繊維質集合体の一方端部を長手方向にイセコミ縫製することによって得られるイセコミ生地を用いる方法が採用されている（特許文献１）。   Conventionally, a fibrous roll has been manufactured by manufacturing a fibrous cylindrical body and then inserting a roll shaft into the hollow of the fibrous cylindrical body. As a method for producing a fibrous cylindrical body, a method using an ISECOMI fabric obtained by sewing one end of a strip-like fibrous assembly made of nonwoven fabric or the like in the longitudinal direction is employed (Patent Document 1).

特許文献１記載の繊維質円筒体の製造方法は以下のとおりである。まず、帯状繊維質集合体の一方端部をミシン糸によってイセコミ縫製して、一方端部の長手方向長さを縮めたイセコミ生地を作成する。このイセコミ生地は、一方端部の長手方向の長さが他方端部の長手方向長さよりも短くなっている。そして、仮軸の外周面に、このイセコミ生地の一方端部が当接するようにして、螺旋状に幾重にも巻回する。これによって、イセコミ生地の一方端部が内周面となり、他方端部が外周面となる円筒体が形成される。その後、仮軸の両端を加圧板に挿入し、円筒体を圧縮する。圧縮後に有機質バインダー又は無機質バインダーを円筒体に含浸し、バインダーを硬化させて固定する。固定後に、加圧板を取り外すと共に仮軸を抜くことによって繊維質円筒体が得られる。この繊維質円筒体の中空にロール軸を挿入することによって、繊維質ロールが得られるのである。   The manufacturing method of the fibrous cylindrical body described in Patent Document 1 is as follows. First, one end of the belt-like fibrous aggregate is sewn with a sewing thread to create an isekomi fabric with the length of one end shortened in the longitudinal direction. The isekomi fabric has a length in the longitudinal direction at one end shorter than a length in the longitudinal direction at the other end. And it winds up in multiple layers helically so that the one end part of this iseko fabric may contact | abut to the outer peripheral surface of a temporary shaft. As a result, a cylindrical body is formed in which one end of the iseko fabric is an inner peripheral surface and the other end is an outer peripheral surface. Thereafter, both ends of the temporary shaft are inserted into the pressure plate, and the cylindrical body is compressed. After compression, the cylindrical body is impregnated with an organic binder or an inorganic binder, and the binder is cured and fixed. After fixing, a fibrous cylindrical body is obtained by removing the pressure plate and removing the temporary shaft. A fiber roll can be obtained by inserting a roll shaft into the hollow of this fibrous cylindrical body.

特開平６−７９０７６号公報JP-A-6-79076

しかしながら、特許文献１記載の方法は、第一に以下のような欠点を有している。繊維質ロールを加圧ロール等として使用する際において、イセコミ生地には高い外力が負荷される場合がある。このとき、イセコミを維持しているミシン糸が切断することがあった。したがって、ミシン糸として高強力糸を採用する必要があるが、縫製されたミシン糸はループ同士が引っ掛けられた状態となっているため、糸そのものは高強力であっても、引っ掛けられた状態では切断しやすいということがあった。また、繊維質ロールは、高温に曝されたり、種々の薬品に曝されることもあり、このような場合にはさらに切断しやすくなるということもあった。ミシン糸が切断すると、イセコミが解除され、繊維質ロールの外周が膨れる傾向となり、ロールとして使用できなくなるという欠点が生じる。   However, the method described in Patent Document 1 has the following disadvantages first. When using a fibrous roll as a pressure roll or the like, a high external force may be applied to the isekomi fabric. At this time, the sewing thread that maintains the knack may break. Therefore, it is necessary to use high-strength yarn as the sewing thread, but since the sewing thread that is sewn is in a state where the loops are hooked, even if the yarn itself is high-strength, It was easy to cut. In addition, the fiber roll may be exposed to high temperatures or exposed to various chemicals, and in such a case, it may be easier to cut. When the sewing thread is cut, isekomi is released, and the outer periphery of the fiber roll tends to swell, resulting in a disadvantage that it cannot be used as a roll.

また、第二に、ミシンによるイセコミは、イセコミ量に限界があり、イセコミを行った一方端部と、その対向端部である他方端部の長手方向長さの差に限界があった。具体的には、イセコミ可能な差動縫製ミシンを用いてイセコミ生地を縫製した場合、他方端部の長さの２０％程度しか、一方端部の長さを短くできないということがあった。イセコミ量に限界があると、内径と外径の差の大きい繊維質円筒体又は繊維質ロールが製造できないという欠点が生じる。   Secondly, there is a limit to the amount of iseko with isekomi by the sewing machine, and there is a limit to the difference in the length in the longitudinal direction between the one end where isekomi was applied and the other end that is the opposite end. Specifically, when an ISEKOMI fabric is sewed using a differential sewing machine capable of ISECOMI, the length of the one end can be shortened by only about 20% of the length of the other end. If there is a limit to the amount of isekomi, there is a disadvantage that a fibrous cylindrical body or fibrous roll having a large difference between the inner diameter and the outer diameter cannot be produced.

そこで、本発明の課題は、第一には、ミシン糸が切断しても、イセコミが解除されないようにして、外周に膨れが生じにくい繊維質ロールの製造方法を提供することにある。   SUMMARY OF THE INVENTION Therefore, a first object of the present invention is to provide a method for producing a fibrous roll that is less likely to bulge on the outer periphery so that sewage is not released even when the sewing thread is cut.

第二に、差動縫製ミシンによるイセコミ量の限界を超えたイセコミ生地を得られるようにして、内外径差の大きい繊維質円筒体又は繊維質ロールの製造方法を提供することにある。   The second is to provide a method for producing a fibrous cylindrical body or fibrous roll having a large difference in inner and outer diameters so as to obtain an ISEKOMI fabric exceeding the limit of the amount of ISEKOMI by a differential sewing machine.

本発明は、二つ折りされた帯状繊維集合体を用い、折り目とイセコミ縫製されたミシン糸との間に、線状の細線を挿入することにより、上記課題を解決したものである。すなわち、本発明は、長手方向に二つ折りされた帯状繊維集合体の折り目の内側を長手方向にミシンでイセコミ縫製する際に、該折り目とミシン糸との間に、線状の細線を挿入してイセコミ縫製することにより、該折り目の長手方向長さを縮めたイセコミ生地を作成し、該イセコミ生地の折り目が仮軸の外周面に当接するようにして螺旋状に幾重にも巻回した後、該仮軸の軸方向に該イセコミ生地を圧縮固定した後、該仮軸を抜くことを特徴とする繊維質円筒体の製造方法に関するものである。また、かかる方法で得られた繊維質円筒体の中空にロール軸を挿入して繊維質ロールを製造する方法に関するものである。   The present invention solves the above-mentioned problems by using a band-shaped fiber assembly folded in two and inserting a linear fine line between a fold line and a sewing thread that is sewn to the side. That is, according to the present invention, when the inside of the fold of the belt-like fiber assembly folded in the longitudinal direction is sewn with a sewing machine in the longitudinal direction, a linear thin line is inserted between the crease and the sewing thread. After creating a isekomi fabric with a reduced length in the longitudinal direction of the fold, and winding the fold of the isekomi fabric in a spiral manner so that the crease of the isekomi abuts the outer peripheral surface of the temporary shaft Further, the present invention relates to a method for producing a fibrous cylindrical body, wherein the temporary shaft is removed after the isekomi fabric is compressed and fixed in the axial direction of the temporary shaft. The present invention also relates to a method of manufacturing a fibrous roll by inserting a roll shaft into the hollow of a fibrous cylindrical body obtained by such a method.

まず、本発明においては帯状繊維集合体１を準備する。帯状繊維集合体１としては、不織布、フェルト又は編織物が用いられる。帯状繊維集合体１の目付は任意であり、一般的に２０〜５００ｇ／ｍ2程度のものが用いられる。また、厚みも任意であり、０．５〜３ｍｍ程度のものが用いられる。そして、この帯状繊維集合体１は長手方向に沿って二つ折りされる。したがって、帯状繊維集合体１の幅が５０ｍｍであると、二つ折りされた帯状繊維集合体１の幅は約２５ｍｍとなる。二つ折りされた帯状繊維集合体１の折り目２の内側に沿って、長手方向に線状の細線３が挿入される。細線３は線状のものであれば任意のものが用いられるが、切断しにくいように、ミシン糸よりも高強力をものを採用するのが好ましい。特に、ステンレス線等の金属線、ポリプロピレンモノフィラメント糸等の合成樹脂製モノフィラメント糸、又はテープ状乃至は紐状の合成樹脂製品といった高強力の細線を用いるのが好ましい。 First, in the present invention, a belt-like fiber assembly 1 is prepared. As the belt-like fiber assembly 1, a nonwoven fabric, a felt, or a knitted fabric is used. The basis weight of the belt-like fiber assembly 1 is arbitrary, and generally about 20 to 500 g / m 2 is used. Moreover, thickness is also arbitrary and a thing about 0.5-3 mm is used. And this strip | belt-shaped fiber assembly 1 is folded in half along a longitudinal direction. Therefore, when the width of the band-shaped fiber assembly 1 is 50 mm, the width of the band-shaped fiber assembly 1 folded in half is about 25 mm. A thin linear wire 3 is inserted in the longitudinal direction along the inside of the fold 2 of the band-shaped fiber assembly 1 folded in half. Any thin wire 3 may be used as long as it is linear, but it is preferable to employ a material having higher strength than the sewing thread so that it is difficult to cut. In particular, it is preferable to use a high-strength thin wire such as a metal wire such as a stainless steel wire, a monofilament yarn made of synthetic resin such as a polypropylene monofilament yarn, or a tape-like or string-like synthetic resin product.

そして、ミシンを用いて、挿入された細線３がミシン糸４と折り目２の間に位置するようにして、折り目２側をイセコミながら縫製する。このイセコミ縫製は、二つ折りされた帯状繊維集合体１の折り目２側を若干波打たせ縮めて縫う方法である。イセコミ縫製は一般のミシンを用いて手動で行うこともできるが、差動縫製ミシンを用いて自動で行うのが合理的である。このイセコミ縫製によって、折り目２側の長手方向長さは、折り目２と反対側の端縁６の長手方向長さよりも短くなる。なお、ミシン糸４も従来公知のものが用いられるが、なるべく高強力のポリエステルマルチフィラメント糸やアラミドマルチフィラメント糸等を用いるのが好ましい。   Then, using the sewing machine, the inserted thin wire 3 is positioned between the sewing thread 4 and the crease 2, and the crease 2 side is sewn while being sought. This isekomi sewing is a method in which the fold 2 side of the band-like fiber assembly 1 folded in half is slightly waved and sewed. Isecom sewing can be performed manually using a general sewing machine, but it is reasonable to perform it automatically using a differential sewing machine. By this isekomi sewing, the length in the longitudinal direction on the side of the fold 2 becomes shorter than the length in the longitudinal direction of the edge 6 on the side opposite to the fold 2. As the sewing thread 4, a conventionally known thread is used, but it is preferable to use a polyester multifilament thread or an aramid multifilament thread that is as strong as possible.

本発明では、帯状繊維集合体１として、腰のない柔軟なものから、腰のある剛直なものまで用いることができる。これは、差動縫製ミシンのイセコミ性能を超えてイセコミが行えるためである。すなわち、差動縫製ミシンの性能だけでイセコミ縫製しようとすると、ミシンの送り量に応じて波打つことが可能な腰のない柔軟な繊維集合体しか使用できない。ミシンの送り量に応じて波打つことができず、反発力で平坦になってしまう、腰のある剛直な繊維集合体は十分なイセコミ縫製が不可能になるのである。しかし、本発明では、折り目２とミシン糸４の間に線状の細線３が挿入されているので、細線３に張力を負荷して、差動縫製ミシンの送り量よりも少ない送り量にすることができる。したがって、単位長さ当たりのイセコミ回数（ミシン糸４の貫通回数）が多くなり、剛直な繊維集合体１であっても、イセコミ縫製が可能となるのである。なお、剛直な帯状繊維集合体１としては、厚みの厚いのものや、その中にバインダー樹脂等を含有しているものが挙げられる。   In the present invention, the belt-like fiber assembly 1 can be used from a flexible one having no waist to a rigid one having a waist. This is because the sewage can be performed beyond the sewage performance of the differential sewing machine. In other words, when trying to sew on the basis of the performance of the differential sewing machine, only a flexible fiber assembly having no waist that can be waved according to the feed amount of the sewing machine can be used. A waisted and rigid fiber assembly that cannot be waved according to the feed amount of the sewing machine and becomes flat due to the repulsive force cannot be sufficiently sewn. However, in the present invention, since the linear thin wire 3 is inserted between the crease 2 and the sewing thread 4, a tension is applied to the thin wire 3 so that the feed amount is smaller than the feed amount of the differential sewing machine. be able to. Therefore, the number of sewage per unit length (the number of penetrations of the sewing thread 4) increases, and sewage sewing can be performed even with the rigid fiber assembly 1. Examples of the rigid belt-like fiber aggregate 1 include those having a large thickness and those containing a binder resin or the like therein.

また、イセコミ回数を多くしてイセコミ生地を作成することにより、二つ折りされた帯状繊維集合体１の折り目２側の長手方向長さと、折り目２の反対側の端縁６の長手方向長さの差を大きくすることができる。たとえば、通常の方法で差動縫製ミシンを使用してイセコミ生地を作成すると、折り目２側の長手方向長さは、端縁６の長手方向長さの２０％以下しか短くすることができない。しかるに、イセコミ回数を多くしてイセコミ生地を作成すると、２０％以上、折り目２側の長手方向長さを短くすることができる。したがって、かかるイセコミ生地を螺旋状に巻回すれば、内径と外径の差の大きい繊維質円筒体を得ることができる。   Further, by creating an ISEKOMI fabric by increasing the number of ISEKOMI, the longitudinal length of the fold 2 side of the band-shaped fiber assembly 1 folded in two and the longitudinal length of the edge 6 on the opposite side of the crease 2 are The difference can be increased. For example, when an ISEKOMI fabric is prepared by using a differential sewing machine in a normal manner, the length in the longitudinal direction on the crease 2 side can be shortened by 20% or less of the length in the longitudinal direction of the edge 6. However, when the isekomi fabric is prepared by increasing the number of isekomi, the length in the longitudinal direction on the crease 2 side can be shortened by 20% or more. Therefore, a fiber cylindrical body having a large difference between the inner diameter and the outer diameter can be obtained by winding the iseko fabric in a spiral shape.

イセコミ縫製により得られたイセコミ生地５は、折り目２側の長手方向長さが、折り目２と反対側の端縁６の長手方向長さよりも短くなっている。したがって、図２に示すような外観となる。このイセコミ生地５の折り目２が、円柱体又は円筒体の仮軸７の外周面に当接するようにして、螺旋状に幾重にも巻回する。具体的には、仮軸７の一方端を加圧板８に挿入した後、この加圧板８の上にイセコミ生地５を螺旋状に幾重にも巻回する。そして、仮軸７の他方端から加圧板９を嵌装し、加圧板８と９に各々対向する圧力を負荷し、巻回されたイセコミ生地５を圧縮する。   In the isekomi fabric 5 obtained by isekomi sewing, the length in the longitudinal direction on the fold 2 side is shorter than the length in the longitudinal direction of the edge 6 on the opposite side to the fold 2. Therefore, the appearance is as shown in FIG. The crease 2 of the iseko fabric 5 is wound spirally and repeatedly so as to contact the outer peripheral surface of the columnar or cylindrical temporary shaft 7. Specifically, after inserting one end of the temporary shaft 7 into the pressure plate 8, the iseko fabric 5 is wound around the pressure plate 8 in a spiral manner. Then, a pressure plate 9 is fitted from the other end of the temporary shaft 7, pressures facing the pressure plates 8 and 9 are loaded, and the wound isekomi fabric 5 is compressed.

圧縮した後、巻回されたイセコミ生地５を固定する。この固定は、使用した帯状繊維集合体１中にバインダー樹脂が含有されている場合には、このバインダー樹脂を軟化又は溶融させて固着させればよい。バインダー樹脂が融点を持たないゴムのような樹脂である場合には軟化させて固着する。また、バインダー樹脂が融点を持つポリエチレンや低融点ポリエステルのような樹脂である場合には溶融させて固着する。帯状繊維集合体１中にバインダー樹脂等の固着させる物質が存在しない場合には、圧縮させた状態で有機質バインダーや無機質バインダー等のバインダーを、巻回されたイセコミ生地５に含浸し、硬化又は融着等の手段で固着させればよい。固着は、一般的に高温雰囲気のオーブン等に入れて加熱した後、冷却することによって行われる。   After compression, the rolled isekomi fabric 5 is fixed. This fixing may be performed by softening or melting the binder resin when the binder resin is contained in the band-shaped fiber assembly 1 used. When the binder resin is a resin such as rubber having no melting point, it is softened and fixed. Further, when the binder resin is a resin such as polyethylene having a melting point or low melting point polyester, it is melted and fixed. In the case where there is no substance to be fixed such as a binder resin in the belt-like fiber assembly 1, the wound ISECOMI fabric 5 is impregnated with a binder such as an organic binder or an inorganic binder in a compressed state and cured or melted. What is necessary is just to fix by means, such as wearing. Fixing is generally carried out by heating in an oven or the like in a high temperature atmosphere and then cooling.

圧縮及び固着が完了すれば、加圧板８及び９を取り外し、さらに仮軸７を抜く。そうすると、巻回されたイセコミ生地５が一体化した繊維質円筒体が得られる。そして、この繊維質円筒体の中空にロール軸を挿入し、両端をフランジ等で固定すれば、繊維質ロールが得られる。一本のロール軸に一個の繊維質ロールを挿入して繊維質ロールとしてもよいが、ワーク長の長い繊維質ロールを得るためには、一本のロール軸を、直列に配置した複数個（二個乃至五個）の繊維質円筒体の中空に挿入して繊維質ロールとするのが好ましい。なお、繊維質ロールの外周面は、一般的に研磨又は研削処理等の仕上処理を行い、所望の平滑度にする。   When compression and fixation are completed, the pressure plates 8 and 9 are removed, and the temporary shaft 7 is further removed. Then, a fibrous cylindrical body in which the wound isekomi fabric 5 is integrated is obtained. And if a roll axis | shaft is inserted in the hollow of this fibrous cylindrical body and both ends are fixed with a flange etc., a fibrous roll will be obtained. One fiber roll may be inserted into one roll shaft to form a fiber roll. However, in order to obtain a fiber roll having a long work length, a plurality of roll shafts arranged in series ( It is preferable to insert into the hollow of 2 to 5) fibrous cylindrical bodies to form a fibrous roll. Note that the outer peripheral surface of the fibrous roll is generally subjected to a finishing process such as polishing or grinding to obtain a desired smoothness.

本発明に係る方法で得られた繊維質ロールは、従来用いられていたゴムロールや金属製ロールに代えて、種々の用途に用いうるものである。具体的には、鋼板等の金属板の製造工程で使用するブライドルロールやピンチロールとして、或いは繊維工業や化学工業等の各種製造設備で使用される絞りロールやニップロールとして使用しうるものである。   The fibrous roll obtained by the method according to the present invention can be used for various applications in place of the conventionally used rubber roll and metal roll. Specifically, it can be used as a bridle roll or pinch roll used in the production process of a metal plate such as a steel plate, or as a squeeze roll or nip roll used in various production facilities such as the textile industry or the chemical industry.

本発明に係る方法で得られた繊維質ロールは、イセコミ生地の折り目内側に線状の細線が挿入されているので、ロール軸の外周面に当接する折り目は、細線とロール軸外周面の間に挟着され固定されている。したがって、繊維質ロールの繊維質円筒体に過大な圧力が負荷され、イセコミ縫製されたミシン糸が切断しても、折り目近傍に設けられたイセコミは解除されにくい。また、イセコミに用いたミシン糸が耐熱性や耐薬品性に劣るものであっても、細線として耐熱性及び耐薬品性に優れたものを用いれば、繊維質ロールが熱や薬品に曝されてミシン糸が切断したとしても、折り目近傍に設けられたイセコミは解除されにくい。よって、本発明によれば、イセコミの解除による繊維質ロールの外周面における膨れが生じにくく、長期間に亙って良好に繊維質ロールを使用しうるという効果を奏する。   In the fibrous roll obtained by the method according to the present invention, a linear fine line is inserted inside the crease of the iseko fabric, so that the fold line that contacts the outer peripheral surface of the roll shaft is between the thin line and the outer peripheral surface of the roll shaft. It is clamped and fixed to. Therefore, even if an excessive pressure is applied to the fibrous cylindrical body of the fibrous roll and the sewing thread sewn by isekomi is cut, the isekomi provided in the vicinity of the fold is not easily released. In addition, even if the sewing thread used for ISEKOMI is inferior in heat resistance and chemical resistance, if a thin wire with excellent heat resistance and chemical resistance is used, the fibrous roll is exposed to heat and chemicals. Even if the sewing thread is cut, it is difficult to release the knack provided near the fold. Therefore, according to the present invention, it is difficult for the outer peripheral surface of the fibrous roll to be swollen due to the release of the dent, and the fibrous roll can be used well over a long period of time.

また、本発明に用いるイセコミ生地は、二つ折りされた帯状繊維集合体の折り目の内側に細線を挿入して、折り目側をイセコミ縫製するものであるため、細線に高張力を負荷して、細線及び帯状繊維集合体の送り量を少なくすれば、イセコミ回数を増加させることができる。イセコミ回数を増加させると、折り目側の長手方向長さと、折り目と反対側の端縁の長手方向長さの差を大きくすることができる。かかるイセコミ生地を螺旋状に巻回して繊維質円筒体を作成すると、内径と外径の差の大きい繊維質円筒体となる。したがって、本発明によれば、任意の内外径差の繊維質円筒体並びにかかる繊維質円筒体を用いて得られた繊維質ロールを得ることができるという効果を奏する。   Further, the isekomi fabric used in the present invention inserts a thin line inside the folded fold of the band-like fiber assembly and sews the crease side, so that a high tension is applied to the thin line, If the feeding amount of the belt-like fiber assembly is reduced, the number of isekomi can be increased. When the number of times of ending is increased, the difference between the length in the longitudinal direction on the crease side and the length in the longitudinal direction on the edge opposite to the crease can be increased. When a fibrous cylindrical body is produced by spirally winding such iseko fabric, a fibrous cylindrical body having a large difference between the inner diameter and the outer diameter is obtained. Therefore, according to this invention, there exists an effect that the fibrous roll obtained using the fibrous cylindrical body of arbitrary inner-outer diameter differences and this fibrous cylindrical body can be obtained.

以下、実施例に基づき本発明を説明するが、本発明は実施例に限定されるものではない。本発明は、二つ折りされた帯状繊維集合体の折り目の内側に細線を挿入してイセコミ縫製したイセコミ生地を用いて繊維質ロールを製造すれば、イセコミ縫製で用いたミシン糸が切断しても、イセコミが解除されにくくなり、繊維質ロールの表面が膨らむのを防止しうるとの知見に基づくものであるとして、解釈されるべきである。   EXAMPLES Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to an Example. According to the present invention, if a fiber roll is manufactured using an ISECOMI fabric that is sewed by inserting a thin line inside a folded fold of a band-like fiber assembly, even if the sewing thread used in ISEKOMI sewing is cut, It should be construed as being based on the knowledge that it is difficult to release isekomi and the surface of the fiber roll can be prevented from swelling.

実施例１
２．７デシテックスの６６ナイロン短繊維と天然のコットン繊維とが混綿されてなり、構成繊維相互間がニトリルブタジエンゴムで結合されてなる不織布（日本バイリーン株式会社製、厚さ１．２ｍｍ、目付２８０ｇ／ｍ2）を準備した。この不織布を幅５０ｍｍにスリットして、帯状繊維集合体を得た。 Example 1
A non-woven fabric in which 2.7 decitex 66 nylon short fibers and natural cotton fibers are mixed and the constituent fibers are bonded with nitrile butadiene rubber (Nippon Vilene Co., Ltd., thickness 1.2 mm, basis weight 280 g) / M 2 ) was prepared. The nonwoven fabric was slit to a width of 50 mm to obtain a strip-shaped fiber assembly.

前記帯状繊維集合体を長手方向に二つ折りして、折り目の内側に沿うようにして、径０．５ｍｍφのステンレス製細線を挿入した。そして、差動縫製ミシンを用いて、折り目とミシン糸との間に細線が位置するようにして、イセコミ縫製を行い、イセコミ生地を得た。なお、ミシン糸は、ポリエステル製紡績糸♯５０を使用した。   The strip-shaped fiber assembly was folded in half in the longitudinal direction, and a stainless steel fine wire having a diameter of 0.5 mmφ was inserted along the inner side of the fold. Then, using a differential sewing machine, isekomi sewing was performed so that a fine line was positioned between the crease and the sewing thread, and an ISEKOMI fabric was obtained. As the sewing thread, polyester spun yarn # 50 was used.

イセコミ生地を用い、図３に示すようにして、径７６ｍｍφの仮軸に螺旋状に幾重にも巻回した。巻回後に、仮軸の両端から加圧板を用いてイセコミ生地を圧縮し、加圧板間の距離が２００ｍｍになるまで圧縮した。このとき、イセコミ生地の密度は約０．７ｇ／ｍ3であった。 As shown in FIG. 3, the isekomi fabric was spirally wound around a temporary shaft having a diameter of 76 mmφ. After winding, the Iseko dough was compressed from both ends of the temporary shaft using pressure plates until the distance between the pressure plates became 200 mm. At this time, the density of the ISEKOMI fabric was about 0.7 g / m 3 .

その後、加圧状態を維持したまま、１２０℃に加熱されたオーブン中で１時間加熱した。この加熱により、イセコミ生地中のニトリルブタジエンゴムが軟化した。加熱後、オーブンから取り出して冷却することにより、イセコミ生地は圧縮状態を維持したまま、固定された。これは、ニトリルブタジエンゴムの軟化及び固着によるものである。   Then, it heated for 1 hour in the oven heated at 120 degreeC, maintaining the pressurization state. This heating softened the nitrile butadiene rubber in the isekomi fabric. After heating, it was taken out of the oven and cooled, so that the iseko fabric was fixed while maintaining the compressed state. This is due to the softening and sticking of the nitrile butadiene rubber.

この後、加圧板を取り外すと共に仮軸を抜いて、外径１２６ｍｍ、内径７６ｍｍ、長さ２００ｍｍの繊維質円筒体を得た。この繊維質円筒体を直列に３個配置して、その中空に径７５ｍｍのロール軸を挿入して、繊維質円筒体の両端をフランジで止め、外径１２６ｍｍ、長さ６００ｍｍのロールを得た。そして、外周面を研削して、外径１２０ｍｍで長さ６００ｍｍの繊維質ロールを得た。   Thereafter, the pressure plate was removed and the temporary shaft was removed to obtain a fibrous cylindrical body having an outer diameter of 126 mm, an inner diameter of 76 mm, and a length of 200 mm. Three fiber cylindrical bodies were arranged in series, a roll shaft having a diameter of 75 mm was inserted into the hollow, and both ends of the fiber cylindrical body were fixed with flanges to obtain a roll having an outer diameter of 126 mm and a length of 600 mm. . Then, the outer peripheral surface was ground to obtain a fibrous roll having an outer diameter of 120 mm and a length of 600 mm.

実施例２
芯がポリプロピレンで鞘がポリエチレンよりなる芯鞘型複合短繊維よりなるニードルパンチ不織布（日本バイリーン株式会社製、厚さ２．５ｍｍ、目付３００ｇ／ｍ2）を準備した。この不織布を幅２５ｍｍにスリットして、帯状繊維集合体を得た。なお、ポリエチレンは後工程でバインダー樹脂として機能するものであるが、この段階では芯鞘型複合短繊維相互間を結合していない。 Example 2
A needle punched nonwoven fabric (Nippon Vilene Co., Ltd., thickness 2.5 mm, basis weight 300 g / m 2 ) made of a core-sheath type composite short fiber having a core of polypropylene and a sheath of polyethylene was prepared. The nonwoven fabric was slit to a width of 25 mm to obtain a band-like fiber assembly. In addition, although polyethylene functions as a binder resin in a post process, the core-sheath composite short fibers are not bonded to each other at this stage.

前記帯状繊維集合体を長手方向に二つ折りして、折り目の内側に沿うようにして、幅３０ｍｍのポリプロピレン紐を丸めながら挿入した。そして、差動縫製ミシンを用いて、折り目とミシン糸との間にポリプロピレン紐が位置するようにして、イセコミ縫製を行い、イセコミ生地を得た。なお、ミシン糸は、ポリエステル製紡績糸♯５０を使用した。   The belt-like fiber aggregate was folded in half in the longitudinal direction, and a polypropylene string having a width of 30 mm was inserted while being rounded along the inner side of the fold. Then, using a differential sewing machine, isekomi sewing was performed so that a polypropylene string was positioned between the crease and the sewing thread, and an ISEKOMI fabric was obtained. As the sewing thread, polyester spun yarn # 50 was used.

イセコミ生地を用い、図３に示すようにして、径３４ｍｍφの仮軸に螺旋状に幾重にも巻回した。巻回後に、仮軸の両端から加圧板を用いてイセコミ生地を圧縮し、加圧板間の距離が１５０ｍｍになるまで圧縮した。圧縮時に外周に若干の膨れが見られたため、再度、イセコミ生地を仮軸に沿うようにして、螺旋状に巻回し直した。この若干の膨れは、ポリプロピレン紐が動いたためで、ポリプロピレン紐は切断していないため、再度の巻回が可能である。ミシン糸が切断した場合は、折り目側のイセコミが解除されるため、再度の巻回が不可能になる。そして、再び加圧板間の距離が１５０ｍｍになるまで圧縮した。このとき、イセコミ生地の密度は約０．７ｇ／ｍ3であった。 As shown in FIG. 3, the isekomi fabric was spirally wound around a temporary shaft having a diameter of 34 mmφ. After winding, the isekomi fabric was compressed from both ends of the temporary shaft using pressure plates until the distance between the pressure plates was 150 mm. Since some swelling was seen on the outer periphery during compression, the ISEKOMI fabric was wound again in a spiral manner along the temporary axis. This slight swelling is due to the movement of the polypropylene string, and the polypropylene string is not cut, so that it can be wound again. When the sewing thread is cut, the crease side selvage is released, so that it is impossible to wind it again. And it compressed until the distance between pressurization plates became 150 mm again. At this time, the density of the ISEKOMI fabric was about 0.7 g / m 3 .

その後、加圧状態を維持したまま、１３０℃に加熱されたオーブン中で１時間加熱した。この加熱により、イセコミ生地中の芯鞘型複合短繊維中の鞘成分であるポリエチレンが溶融した。加熱後、オーブンから取り出して冷却することにより、イセコミ生地は圧縮状態を維持したまま、固定された。これは、ポリエチレンの溶融及び固着によるものである。   Then, it heated for 1 hour in the oven heated at 130 degreeC, maintaining the pressurization state. By this heating, polyethylene which is a sheath component in the core-sheath type composite short fiber in the ISEKOMI fabric was melted. After heating, it was taken out of the oven and cooled, so that the iseko fabric was fixed while maintaining the compressed state. This is due to melting and sticking of the polyethylene.

この後、加圧板を取り外すと共に仮軸を抜いて、外径５９ｍｍ、内径３４ｍｍ、長さ１５０ｍｍの繊維質円筒体を得た。この繊維質円筒体を直列に２個配置して、その中空に径３４ｍｍのローラーコンベア軸を挿入して、繊維質円筒体の両端をフランジで止め、外径５９ｍｍ、長さ３００ｍｍのロールを得た。そして、外周面を研削して、外径５５ｍｍで長さ３００ｍｍの繊維質ロールを得た。   Thereafter, the pressure plate was removed and the temporary shaft was removed to obtain a fibrous cylindrical body having an outer diameter of 59 mm, an inner diameter of 34 mm, and a length of 150 mm. Two fiber cylindrical bodies are arranged in series, a roller conveyor shaft having a diameter of 34 mm is inserted into the hollow, and both ends of the fiber cylindrical body are fixed with flanges to obtain a roll having an outer diameter of 59 mm and a length of 300 mm. It was. Then, the outer peripheral surface was ground to obtain a fibrous roll having an outer diameter of 55 mm and a length of 300 mm.
