DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific example of an embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show an embodiment of the present invention, wherein 1 is a stretchable warp thread arranged substantially parallel to the longitudinal direction X, and a width direction crossing the warp 1 in the longitudinal direction X. By arranging a large number of composite weft yarns 2 substantially parallel to Y, it is woven into a woven fabric.

The warp yarn 1 is formed to have a thickness of 2240D (denier) by covering a core yarn 1a made of a polyurethane fiber yarn with a spun yarn 1b obtained by twisting a single polyester fiber yarn. It has elasticity. The composite wefts 2, 2,... Arranged at the corresponding positions of the loops R, R,. The weft yarns 2 are fixed to each other, so that the composite weft yarns 2 and 2 have a structural fabric structure against tensile force, compressive force, and frictional force without inadvertently shifting in the vertical and horizontal directions or moving.
.. And the warp yarns 1, 1,. Loops R, R
For example, knitting is applied to form...
The reason why the spun yarn 1b is used for the warp yarn 1 is to prevent the fibers from entangled with the later-described spun yarn 4 included in the composite weft yarns 2, 2,.

The composite weft 2 is a composite yarn composed of a synthetic resin yarn 3 of a desired diameter and a desired number, a spun yarn 4 as a woven yarn, and a thermoplastic synthetic fiber yarn 5 arranged in a bundle. Is done.

In this embodiment, as the synthetic resin yarn 3 constituting the composite weft 2, three polyester resin yarns 3a, 3b and 3c of 420 denier (D) are used. In this case, the illustration is a typical embodiment, and the use of the polyester resin yarns 3a, 3b, 3c for the synthetic resin yarn 3 is an example, and the material is not limited to this, and the rigidity and flexibility are sufficient. Any material may be used as long as it has good workability. Moreover, the used yarn diameter and the number of used yarns are also examples, and are not limited thereto. For example, among the synthetic resin yarns 3, one polyester resin yarn 3a is pulled out from the curved ear 7 together with the synthetic resin fiber yarns 4a and 4b to be the later-described spun yarn 4 as a woven yarn, and becomes the later-described warp yarn 1A. By being wound, the adjacent curved ears 7, 7,... Are connected to each other.

As the woven yarn, a spun yarn 4 in which a plurality of, for example, two synthetic resin fiber yarns 4a and 4b having a thickness of 20th yarn are twisted into one polyester fiber yarn is used.

The thermoplastic synthetic fiber yarn 5 is, for example, a polyamide synthetic fiber yarn having a thickness of 150 denier (D), and has a softening point of 60 ° C. to 130 ° C. When the inside belt is used as an inside belt in a waist portion of a trouser such as a skirt by being heated with an iron, the inside belt is easily and reliably adhered to the back surface of the top fabric K, and thus the inside belt for the front fabric K is formed. To prevent inadvertent displacement and peeling. In this case, the use of a polyamide-based synthetic fiber yarn as the thermoplastic synthetic fiber yarn 5 is an example, and the thermoplastic synthetic fiber yarn 5 may be, for example, a polyethylene synthetic fiber yarn, a polystyrene synthetic fiber yarn, a polyvinyl acetate. And the like. As shown in FIG. 1, the composite weft 2 having the above composition and structure is continuously formed in a substantially S-shape in the longitudinal direction X.
Width direction Y crossing in the longitudinal direction X by being bent
Many are routed to form the weft.

At this time, of the synthetic resin yarns 3 of the composite weft 2, the polyester resin yarns 3a, 3
b, 3c and the thermoplastic synthetic fiber yarn 5 are respectively arranged in the respective loops R formed by the elastic warp yarns 1 in the drawing, so that the composite weft yarn 2 is expanded and contracted by the expansion and contraction of the loop R. The inadvertent movement of the warp 1 is prevented by the elastic tightening, but this is merely an example, and the polyester resin yarns 3a, 3b, 3c and the heat .. May be arranged in loops R, R... ... The routing of the synthetic fiber yarn 5 in the individual loops R, R... With respect to the polyester resin yarns 3a, 3b, 3c is performed by the polyester resin yarns 3a, 3b, 3c.
Thereby, the rigidity of the inside belt in the width direction Y is reliably exhibited. In addition, by heating the iron or the like, the synthetic fiber yarn 5 effectively exerts the heat-fusing property to the surface cloth K, securely adheres the inside belt, and the polyester resin yarns 3a, 3b, 3c are overheated by high temperature. This is to prevent the finish of the product from being deteriorated due to the heat fusion and the occurrence of the yield from being deteriorated. In addition, the synthetic fiber yarns 5 reliably prevent the warp yarns 1 from moving with respect to the composite weft yarns 2 by bonding by heating, so that the fibers of the inside belt are frayed or the weave of the woven fabric is unraveled and becomes structurally weak. Also helped to prevent

Reference numeral 7 is formed adjacent to the front and rear sides of the inside belt in the width direction Y by bending the composite weft 2 continuously in a substantially S-shape in the longitudinal direction X of the inside belt. Are curved U-shaped curved ears, and the curved ears 7, 7,...
Two polyester resin yarns 3b of 20 denier (D),
3c exhibits a rigidity and is formed in a substantially U-shaped plane, so that it exhibits an elastic force against an external force F such as a compressive force and a pressing force.

1A are warp yarns arranged in the longitudinal direction X on both left and right sides of the inside belt in the width direction Y of the inside belt and inside the reinforcement warp yarns 1'A. The warp yarns 1A, 1A have the same structure and the same material and the same diameter as the warp yarn 1. And this warp 1
A is a curved ear formed adjacently to the front and rear at the left and right sides in the width direction Y of the inside belt by bending the composite weft 2 continuously in a substantially S-shape in the longitudinal direction X of the inside belt. Are connected to each other so as to be able to expand and contract in the longitudinal direction X.

Reference numeral 8 denotes a reinforcing edge portion of the fabric structure. The reinforcing edge portions 8 are formed on both left and right sides in the width direction Y of the inside belt. Further, the reinforcing edges 8, 8 are provided with the warp yarns 1A, 1A for binding the front and rear curved ear portions 7, 7,... To each other in the longitudinal direction X, and outwardly in parallel with the warp yarns 1A, 1A. Reinforcing warp yarns 1'A, 1'A to be wired
And the synthetic resin fiber yarns 4a, 4b as the woven yarns drawn from the curved ears 7, 7,... Formed by the composite weft yarn 2.
And the polyester resin yarn 3a wound around the warp yarns 1A, 1A, and knits a weave of a structurally strong woven structure at the edge of the inside belt and is formed to be stretchable in the longitudinal direction X. doing.

The reinforcing warp yarn 1'A is made of, for example, a polyurethane fiber core 1'a having an outer periphery covered with a polyester fiber 1'b and having a thickness of 70 counts. It has elasticity.
The reinforcing warp yarn 1'A has a thickness of the reinforcing edges 8, 8 of the woven fabric formed on the left and right edges of the inside belt by using an elastic yarn having a smaller diameter than the warp yarns 1 and 1A. This is because the inside belt is formed to have an averaged thickness so as not to be thicker than the central portion in the width direction Y of the inside belt.

The weft yarn 2 is contained in the composite weft yarn 2.
Since the synthetic resin fiber yarns 4a and 4b are formed by the spun yarn 4 in which polyester fibers are twisted, a desired number of the woven yarns drawn toward the reinforcing warp yarn 1'A, for example, one The synthetic resin fiber yarn 4a is fixed to the upper and lower reinforcing warp yarns 1'A, 1'A by being wound a desired number of times. Moreover, this synthetic resin fiber yarn 4a
Together with the reinforcing warp yarns 1'A, 1'A, the reinforcing edges 8,
8 is used to form high strength. Further, the remaining synthetic resin fiber yarns 4b forming the spun yarns 4 are branched and routed to the adjacent composite weft yarns 2 routed in the width direction Y of the inside belt, so that the reinforcing edge 8 becomes strong. Knitted into a woven fabric. Thus, the woven fabric composed of the composite weft yarn 2 and the warp yarn 1 does not shift or move longitudinally or laterally with respect to external forces such as tensile force, compressive force, frictional force and the like at the left and right edges, without loosening and fraying, and has a strong structure. And woven in a stretchable manner.

As described above, one embodiment of the present invention relates to the warp 1 which is routed substantially parallel to the longitudinal direction X of the inside belt.
The woven fabric is woven by the composite weft 2 that is routed substantially parallel to the warp 1 in the width direction Y crossing the longitudinal direction X of the inside belt. The warp yarns 1 routed substantially parallel to the longitudinal direction X of the inside belt are covered by a spun yarn 1b formed by twisting a single polyester fiber yarn around a core yarn 1a made of a polyurethane fiber yarn. Since the inner belt having a thickness of 2240 denier (D) is used, the inside belt exhibits elasticity in the longitudinal direction X.

A large number of composite weft yarns 2 arranged in the width direction Y of the inside belt are continuously arranged in a substantially S-shape and bent in the longitudinal direction X. Moreover, the composite weft 2 is a synthetic resin yarn 3 having a desired diameter and a desired number, for example, in this embodiment, three polyester resin yarns 3a, 3b, 3c of 420 denier (D) and two synthetic resin fibers as a woven yarn. Spun yarn 4 consisting of yarns 4a and 4b
And the composite yarn composed of the thermoplastic synthetic fiber yarn 5 is arranged in a bundle in the width direction Y of the inside belt.
When the inside belt is used as an inside belt inserted into a waist portion such as pants or a skirt, the inside belt is in the width direction Y of the inside belt due to the rigidity of the synthetic resin thread 3.
Without being carelessly bent, even if it is bent, the structure is restored by the flexibility, resulting in a robust structure.

The composite weft yarn 2 is formed around a core yarn 1a made of polyurethane fiber yarn by a spun yarn 1b obtained by twisting a plurality of, for example, two synthetic resin fibers having a thickness of 20 counts into one. Are inserted into the corresponding loops R, R... Knitted by the elastic warp 1 covered with the loops R, R.
, So that the warp yarn 1 and the composite weft yarn 2 are fixed to each other to form an inside belt having a fabric structure. For this reason, the warp 1 and the composite weft 2 do not inadvertently displace from each other in the warp and the transverse direction, and do not move, and the tensile force,
A woven fabric structure that is structurally strong against compression force and friction force is formed and does not collapse. In addition, the inside belt exerts rigidity by being knitted in the width direction Y by inserting the desired diameter, the desired number, and three synthetic resin yarns 3 in the loop R formed of the warp yarns 1 as described above. Therefore, the inside belt does not bend in the width direction Y and the edge of the waist portion does not lose its shape, and the shape retention property is reliably exhibited. Further, the inside belt expands and contracts in the longitudinal direction X due to the elasticity of the warp yarn 1 and expands and contracts according to the wearing of pants, skirts, and the like, and does not cause any discomfort.

Further, by bending the composite weft 2 continuously in a longitudinal direction X in a substantially S-shape, the composite weft 2 is formed on both the left and right sides of the inside belt, and the curved ears 7,
7 and 7 are formed by bending the two polyester resin yarns 3b and 3c of 420 denier (D) into a substantially U-shaped plane as shown in FIGS.
It exerts a resilient force due to its rigidity against an external force F such as a pressing force. Therefore, when the user wears pants or the like as in the conventional case shown in FIG.

At this time, the composite weft thread 2 continuously bends in the longitudinal direction X in a substantially S-shape, so that the curved ear portions 7, 7... Is
Since the warp yarns 1 are bound in the longitudinal direction X by 1A, 1A, the pitch P is substantially equal between the curved ear portions 7, 7,.
In the longitudinal direction X, the inside belt exhibits an average elasticity as a whole.

Moreover, the inside belt is located on the left and right sides and is approximately outward on the outer side with respect to the warp yarns 1; 1A, 1A in order to bind the curved ear portions 7, 7,. The reinforcing warp yarns 1'A, 1'A are arranged in parallel, and two synthetic resin fiber yarns 4a, 4b are formed as weaving yarns from the curved ears 7, 7,... Spun yarns 4 and 4 obtained by twisting polyester fiber yarns into one are drawn out, and one synthetic resin fiber yarn 4a is wound a plurality of times around the outer reinforcing warp yarns 1'A and 1'A. The strength is increased together with the reinforcing warp yarns 1'A, 1'A by being fixed by being carried out and the like.
b is reinforced with respect to adjacent composite weft yarns 2 laid in the width direction Y of the inside belt, so that the reinforcing edges 8 are formed on the left and right sides with increased strength.

The reinforcing edges 8, 8 are curved ears 7, 7
..; 7A in the longitudinal direction X, the reinforcing warp 1'A is routed in parallel to the warp 1... 1A, and from the vicinity of the curved lugs 7, 7. The polyester resin yarn 3a is wound around the warp yarn 1A together with the spun yarn 4 to be drawn out, and is arranged substantially concentrically with the curved ears 7, 7,...; 7, 7,. Knitted into a woven fabric. As described above, since the reinforcing edges 8, 8 are knitted in a knitted structure, the fibers are not loosened or loosened against an external force such as a tensile force, a compressive force, or a frictional force, and the structure is finished firmly. The warp yarns 1'A and the warp yarns 1 ... 1A exhibit elasticity in the longitudinal direction X of the inside belt. Moreover, the polyester resin yarn 3a increases the rigidity of the inside belt in the width direction Y by arranging the synthetic resin fiber yarn 4b branched from the synthetic resin fiber yarn 4a with respect to the adjacent composite weft yarn 2, thereby increasing the strength. Having.

Further, since the composite weft 2 contains, for example, a polyamide synthetic fiber yarn having a thickness of 150 denier (D) as the thermoplastic synthetic fiber yarn 5, the synthetic fiber yarn 5 is formed by using an iron. Is heated to 60 ° C ~ 13
The inside belt can be softened by heating at about 0 ° C., and the inside belt can be adhered to the outer fabric K such as trousers and skirt by further heat fusion. Then, the inside belt is integrated with the surface cloth K, so that it is possible to prevent unintentional shift movement and peeling. Moreover, when the composite weft 2 is heated, the synthetic fiber yarns 5 contained in the composite weft 2 are melted and the inside belt is adhered to the surface fabric K. Therefore, the inside belt is adhered to the surface fabric using an adhesive. Unlike the conventional method, even if the thickness of the surface cloth K is thin, the adhesive is exposed to the outside from the texture even in the case where the texture is rough, and the pattern in which the adhesive is expressed on the surface cloth K is used. There is no inconvenience such as soiling.

At this time, the one shown in the figure is a typical embodiment, and among the synthetic resin yarns 3, a polyester resin yarn 3 a, 3 b, 3 c having a desired diameter and a desired number and a thermoplastic synthetic fiber yarn 5 are combined. Each of the loops R, R... Formed by the warp yarns 1 is routed together as a bundle of composite yarns, but this is an example. For example, the polyester resin yarns 3a, 3b, 3c and the synthetic fiber yarn 5 have different loops R, R,.
It may be arranged individually in the inside. in this way,
When the polyester resin yarns 3a, 3b, 3c are routed in the individual loops R, R,... With respect to the synthetic fiber yarn 5, the polyester resin yarns 3a, 3b, 3c exhibit rigidity, and are synthesized. The heat fusion property of the fiber yarn 5 to the surface cloth K can be effectively exhibited.

In the above embodiment, the inside belt inserted into the waist portion of the pants, skirt or the like has been described. However, the present invention is not limited to this. It can also be applied as a core.

In the above embodiment, the composite weft yarn 2 including the synthetic resin yarn 3 and the woven yarn is bent in a substantially S-shape continuously in the longitudinal direction X, so that the width of the weft yarn having the curved ear portions 7 at the front and rear is obtained. Although a large number of wires are arranged in the direction Y, a large number of composite wefts 2 having the curved ears 7 may be arranged in the longitudinal direction X. In the above embodiment, the curved ear portions 7 are provided on the left and right sides of the inside belt. However, the curved ear portions 7 are formed only on one of the upper edge and the lower edge of the inside belt. Is also good.

In the above embodiment, the composite weft yarn 2 is formed by using three synthetic resin yarns of the same diameter as the synthetic resin yarn 3, but this is merely an example, and the synthetic resin yarn 3 has a large diameter. The details and the number of used pieces can be freely increased or decreased and can be selected in any combination. In the above embodiment, the composite weft 2
The thickness and the number of used synthetic yarns of spun yarns as the woven yarns used for the yarn and the warp yarn 1 can be freely increased and decreased. For example, the installation width of the inside belt, the thickness of the used synthetic resin yarn, and the number of used yarns , Rigidity and the like can be arbitrarily selected. Also, a single yarn may be used as the woven yarn without necessarily using a spun yarn.

[0038]

The inadvertent movement of the warp 1 is prevented by the elastic tightening, but this is merely an example, and the polyester resin yarns 3a, 3b, 3c and the heat .. May be arranged in loops R, R... ... The routing of the synthetic fiber yarn 5 in the individual loops R, R... With respect to the polyester resin yarns 3a, 3b, 3c is performed by the polyester resin yarns 3a, 3b, 3c.
Thereby, the rigidity of the inside belt in the width direction Y is reliably exhibited. In addition, by heating the iron or the like, the synthetic fiber yarn 5 effectively exerts the heat-fusing property to the surface cloth K, securely adheres the inside belt, and the polyester resin yarns 3a, 3b, 3c are overheated by high temperature. This is to prevent the finish of the product from being deteriorated due to the heat fusion and the occurrence of the yield from being deteriorated. Moreover, the synthetic fiber yarns 5 and out fraying fibers mutual inside the belt to reliably prevent the movement to the composite weft 2 of warp yarns 1 by bonding by heat, become structurally vulnerable melts knitting th knitted product tissue It has also helped to prevent
