変形が生じやすいという欠点があつた。 Conventionally, woven fabrics have generally been used as inside belts, but since woven fabrics are expensive and have high production costs, various inexpensive alternative inside belts have been investigated. For such inside belts, adhesive-bonded nonwoven fabrics, resin-treated nonwoven fabrics, and reinforcing materials such as films have been proposed. It has the drawbacks of poor strength and easy stretching in the longitudinal direction. On the other hand, inside belts using spunbond nonwoven fabrics have also been proposed, but these also have the drawbacks of being prone to delamination when the basis weight becomes large, and dimensional deformation due to heat shrinkage.

接着性を示さないものであればよい。 The inside belt 1 of the present invention is made by bonding webs containing thermoadhesive fibers by thermocompression bonding, and the web used here is a two-layer stack of a unidirectional web layer A2 and a web layer B3, or a unidirectional web layer A2 and a web layer B3. It has a layered structure consisting of the above layers, and also includes a sandwich structure in which one layer is sandwiched between the other layers. In addition, each layer of the unidirectional web layer A2 and web layer B3 contains heat-adhesive fibers and non-thermally-adhesive fibers made of synthetic fibers such as polyester and polyamide. To get at least
Preferably, it contains 20% by weight of thermobondable fibers. The heat-adhesive fibers used in the present invention are preferably all-melting heat-adhesive fibers or core-sheath type or side-by-side type composite fibers containing a heat-adhesive component as one component. It is desirable that the melting point of the thermoadhesive component is in the range of 180 to 220°C in order to prevent thermal deformation during processing. Furthermore, the non-thermally adhesive fibers used in the present invention may have a higher melting point than the thermally adhesive fibers and do not exhibit adhesive properties at the temperature during thermocompression bonding.
上記の一方向性ウエブ層Ａ２はウエブ中に少な
くとも10重量％含まれており、構成繊維の大部分
が実質的にインサイドベルトの長手方向に配列さ
れているので、インサイドベルトの長手方向への
伸びを止め、引張強度を向上させる効果がある。 The above-mentioned unidirectional web layer A2 is contained in the web at least 10% by weight, and most of the constituent fibers are substantially arranged in the longitudinal direction of the inside belt, so that the elongation in the longitudinal direction of the inside belt is It has the effect of stopping and improving tensile strength.
なお、一方向性ウエブ層Ａ２を構成する繊維に
非熱接着性繊維として単繊維伸度の小さい繊維を
使用すると、インサイドベルトの長手方向におけ

のでより好ましい。 In addition, if fibers with low single fiber elongation are used as non-thermally bondable fibers for the fibers constituting the unidirectional web layer A2, effects such as elongation prevention and tensile strength in the longitudinal direction of the inside belt will be further improved. preferable.
一方、ウエブ層Ｂ３はウエブ中に少なくとも20
重量％含まれており、構成繊維の大部分が実質的

角度は30〜150゜であることが望ましい。 On the other hand, web layer B3 has at least 20
% by weight, and most of the constituent fibers substantially intersect with the longitudinal direction of the inside belt, increasing the impact resilience of the inside belt in the width direction and preventing it from tearing in the longitudinal direction. . Therefore, it is desirable that the angle formed by the intersection of the fibers constituting the web layer B3 and the longitudinal direction of the inside belt is 30 to 150 degrees.
前記一方向性ウエブ層Ａ２とウエブ層Ｂ３とを

好ましく、また線状凹部４は0.6〜2.0mmの所定間
隔を置いて設けるのが好ましい。ただし、ここで
所定間隔とはインサイドベルトの長手方向の断面
において互いに隣り合う凹部の相対応する２点間
の距離をいう。上記のように線状凹部４を0.6〜
2.0mmの間隔で設けると、表地の表面荒れを防ぐ
という効果も奏するのでよい。 Linear recesses 4 are provided at predetermined intervals on the surface of the web including the unidirectional web layer A2 and web layer B3. The linear recesses 4 are formed by thermocompression bonding using an embossing roll or the like at a temperature and pressure that allow the thermoadhesive fibers to bond, thereby also bonding the fibers of the web. In order to obtain the strength and rigidity required for the inside belt, the linear recess 4
It is desirable that the area of the linear recess 4 accounts for 20 to 50% of the area of the inside belt on the surface where the linear recess 4 is provided, and the depth of the linear recess 4 is preferably 0.1 to 1.0 mm. are preferably provided at predetermined intervals of 0.6 to 2.0 mm. However, the predetermined interval here refers to the distance between two corresponding points of adjacent recesses in the longitudinal cross section of the inside belt. As mentioned above, the linear recess 4 is 0.6 ~
It is preferable to provide them at intervals of 2.0 mm because this also has the effect of preventing the surface of the outer material from becoming rough.
本考案の線状凹部４は幅方向の反発弾性を得る
ためにインサイドベルトの長手方向と略直交して
いなければならないが、その形状は直線状、曲線
状または波線状のいずれであつてもよい。 The linear recess 4 of the present invention must be substantially orthogonal to the longitudinal direction of the inside belt in order to obtain repulsion resilience in the width direction, but its shape may be linear, curved, or wavy. .
また、線状凹部４はウエブのウエブ層Ｂ３側の
表面に設けられている方が好ましい。これは線状

分となるおそれがあるからである。 Furthermore, it is preferable that the linear recesses 4 be provided on the surface of the web on the web layer B3 side. This is because when the linear recesses 4 are provided on the surface of the web on the unidirectional web layer A2 side, the constituent fibers of the unidirectional web layer A2 are shredded by thermocompression bonding, reducing the tensile strength in the longitudinal direction. This is because the effect of preventing extension in the direction may be insufficient.

It may also be used by pasting together. In addition, in order to streamline the sewing process, the inside belt 1 of this invention
It may be used by applying an adhesive resin to one or both sides.

The fabric weight was formed by mixing 40% by weight of core-sheath type polyester fiber and using a normal cardin machine.
A unidirectional web layer of 40 g/m 2 is laminated with a cross web layer of the same fiber composition as above with a basis weight of 170 g/m 2 ,
A web with a basis weight of 210 g/m 2 was obtained. The cross-web layer side surface of this web is thermocompressed using an embossing roll heated to 200℃ at a linear pressure of 50 kg/cm to bond the fibers.The resulting embossed pattern is the fiber of the unidirectional web layer. The recesses were linear in shape and were approximately perpendicular to the arrangement direction of the recesses, with an interval of 1.0 mm and a depth of 0.4 mm. Thereafter, the thermocompression-bonded sheet was cut into 3 cm width pieces using a slitter so that the fiber arrangement direction of the unidirectional web layer and the longitudinal direction of the inside belt substantially coincided. The obtained inside belt has appropriate rigidity and resilience in the width direction, and also has 5
% initial modulus is 15Kg/3cm, showing difficulty in elongation in the longitudinal direction, and tensile strength in the longitudinal direction is 45Kg/3cm.

する極めて有用なものである。 As described above, the inside belt of the present invention has a unidirectional web layer A of at least 10% by weight in which substantially most of the fibers are arranged in the longitudinal direction of the inside belt, and a unidirectional web layer A in which substantially most of the fibers are arranged in the longitudinal direction of the inside belt. The surface of the web, which includes at least 20% by weight of the web layer B that intersects with the longitudinal direction of the belt, is provided with linear recesses at predetermined intervals that are substantially perpendicular to the longitudinal direction of the inside belt, so that it has appropriate rigidity. It has rebound resilience in the width direction, high tensile strength in the longitudinal direction, and is difficult to stretch in the longitudinal direction. In addition, since the inside belt of the present invention is mainly composed of stretched fibers, it does not undergo heat shrinkage during the sewing process and has excellent dimensional stability, unlike inside belts made of spunbond nonwoven fabric. Furthermore, products of various qualities can be obtained simply by changing the type and composition of the constituent fibers. Furthermore, the inside belt of this invention is made by thermo-compression bonding of thermo-adhesive fibers.
Washing resistance is also good because the fibers are strongly bonded. As described above, the inside belt of the present invention is extremely useful as it simultaneously satisfies various properties required of an inside belt when used for skirts, pants, etc.
