The elements on larger scale which show the state of the structure and scouring of 2nd Example, dry heat processing, water-repellent processing, and a rearrangement process. The perspective view which shows a 3rd Example.

  Hereinafter, embodiments of the composite stretchable woven fabric according to the present invention will be described with reference to the drawings.

Fig.1 (a) is the elements on larger scale which show the woven fabric 100 of the composite elastic | stretch fabric which is a 1st Example.
In FIG. 1, 10 is a highly stretchable fiber such as polyurethane, 20 is a low stretchable fiber such as polyester, 30 is a high stretchable portion, 40 is a low stretchable portion, and 60 is a boundary surface between a high stretchable portion and a low stretchable portion. , 100 is the composite stretchable woven fabric of the first embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or a dobby loom.
The composite elastic woven fabric 100 is an arm cover, leg cover, coverall with integrated functions such as dust-proof function that requires fitting of the opening, clothing with multiple structures, clothing such as corsets, tights, and T-shirts. A woven fabric that serves as a base of the fabric, and is woven with warp yarn (warp) and weft yarn (weft).

  The highly stretchable fiber 10 is polyurethane, and a fiber having high stretchability can be substituted for this fiber. The low-stretch fiber 20 is selected from polyester, polyamide (nylon), cupra, cotton, wool, acrylic, rayon, hemp, silk, acetate, etc. and non-designated fibers (such as tencel, lyocell, and polylactic acid fiber). Similar to these fibers, fibers having low stretchability can be substituted.

  The high stretchable part 30 is composed of warp yarns 20 having low stretchability and weft yarns composed of both low stretchable fibers 20 and highly stretchable fibers 10. The type of fiber selected can be changed as appropriate. The weft yarn of the high stretch portion plays a role of covering the highly stretchable fiber 10 with the low stretchable fiber 20. The low stretchable part 40 comprises both warps and wefts with fibers 20 having low stretchability. The boundary surface 60 between the high expansion / contraction part 30 and the low expansion / contraction part 40 is the boundary of the degree of expansion / contraction, and 30 and 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The boundary surface 60 does not have a hole or the like generated when being sewn.

  FIG. 1B is a partially enlarged view showing a state 110 after scouring, dry heat treatment, water repellent processing, and rearranging of FIG. 1A in the first embodiment. The highly stretchable portion 32 that has been subjected to scouring, drying, water repellency processing, and organizing processing is contracted because it is composed of the highly elastic fiber 10, and the low stretching portion 42 that has been subjected to scouring, dry heat treatment, water repellency processing, and organizing processing is Since it is composed of the low-stretch fiber 20, it shows a state where it does not shrink.

Here, the contents and procedures of scouring, dry heat treatment, water repellent processing, and rearranging will be described below.
(1) Scouring: The woven fabric contains impurities such as glue and oil used when weaving. In this process, the impurities are removed and the dough is placed in hot water at around 75 ° C. in a room heat environment. By this process, impurities such as oil are washed out even if the fabric contains polyurethane fibers that are generally easy to attach oil. In addition, the polyurethane fiber that has been hardened and stretched with glue contracts by the removal of the glue. At this point, the polyurethane fiber is apt to change in terms of stretch and is unstable.
(2) Dry heat (warm air) treatment: In order to remove moisture from the dough whose impurities have been purified by scouring, it is a process of hanging by a machine such as a boiler or drying in the sun (natural drying). The polyurethane fiber containing moisture shrinks further than being dried.
(3) Water repellent treatment: a step of immersing a water repellent liquid composed of a resin or the like at around 40 ° C. twice. As a result, the water repellent is fixed to the surface of the fabric and repels moisture.
(4) Arrangement processing: Drying with hot air at a temperature of about 165 ° C. or more to fix the water repellent liquid. This high-temperature drying step (heat setting) further improves the water repellency, and the polyurethane fibers are further shrunk and fixed to stabilize the stretch.

  Due to scouring, dry heat treatment, water repellent treatment, and rearrangement, there is a difference in the degree of stretch between the high stretch portion and the low stretch portion. This difference is due to the change in the hybrid ratio of the highly stretchable fibers used in the wefts of the high stretch part and the type of fiber selected as the low stretch fiber used in the wefts. It is possible to make a difference in the degree of stretching. In addition, it is possible to produce a woven fabric having any desired degree of stretch by changing the hybrid ratio arbitrarily or by selecting the type of fiber selected as the low stretch fiber.

  Further, the scouring, dry heat treatment, water repellent treatment, and rearrangement process make the boundary surface 60 between the high stretchable portion and the low stretchable portion noticeable, but since 60 is not stitched, the boundary surface is continuous without any holes. Connected. Therefore, unlike woven fabrics sewn in the conventional manner, it does not have a hole, so that any substance such as granular, powder, or liquid does not enter from the outside, water repellent effect that repels water, air It is effective in preventing contamination from harmful substances such as radioactive substances contained in dust scattered inside. Moreover, it is not necessary to prepare and sew fabrics having different degrees of stretch, and since there is no trace of stitching on the boundary surface 60, the appearance is excellent in appearance.

  Even in the case of putting a pattern in the woven fabric process, the pattern can be applied continuously and integrally in all the portions having different degrees of stretch as in the present invention. In addition, various patterns such as a check pattern that is applied in a conventional pattern print can be obtained by switching the woven yarn to a series of woven fabrics. In the conventional composite stretch woven fabric obtained by stitching a plurality of woven fabrics having different stretch properties, it is necessary to apply a pattern to each of the plurality of woven fabrics. In this respect, the woven fabric is advantageous in that the number of steps can be reduced, and even a complicated pattern can be easily decorated such as a pattern at a time.

Fig.2 (a) is the elements on larger scale which show the composite elastic woven fabric 200 of the 2nd Example.
In FIG. 1, 10 is a highly stretchable fiber such as polyurethane, 20 is a low stretchable fiber such as polyester, 30 is a high stretchable portion, 50 is a middle stretchable portion, 62 is a boundary surface between the high stretchable portion and the middle stretchable portion. , 200 is the composite stretchable woven fabric of the second embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom.

  The high stretchable part 30 is composed of warps with low stretchable fibers 20 and wefts with both low stretchable fibers 20 and highly stretchable fibers 10. Can be changed. Further, the type of 20 selected fibers can be appropriately changed depending on the desired degree of stretching. The middle stretchable part 50 has a low stretchability compared to the high stretchable part 30 and refers to a part having a high stretchability compared to the low stretchable part 40, and the weft is made of the low stretchable fiber 20 and the highly stretchable fiber 10. Both are configured, and the distribution of 10 and 20 and the hybrid ratio can be changed as appropriate at a lower stretch degree than that of the high stretch part, depending on the desired stretch degree. Further, the type of 20 selected fibers can be appropriately changed depending on the desired degree of stretching. A boundary surface 62 between the high stretchable portion 30 and the middle stretchable portion 50 is a boundary of the stretch degree. Since 30 and 50 are integrally woven, a hole portion or the like generated when sewing is performed on a portion corresponding to a joint. not exist.

  FIG. 2B is a partially enlarged view showing a state 210 after scouring, dry heat treatment, water repellent processing, and rearranging processing of FIG. 2A in the second embodiment. The highly stretchable portion 32 that has been subjected to scouring, dry heat treatment, water repellent processing, and rearrangement is made of the highly stretchable fiber 10 and thus contracts, and the middle stretchable portion 52 that has been subjected to scouring, dry heat treatment, water repellent processing, and rearrangement processing. Since the structure also includes the highly stretchable fiber 10, it contracts with a moderate degree of stretch as compared with the high stretch portion 32.

  In the second embodiment, the middle stretchable portion is stretchable compared to the low stretchable portion of the first embodiment. Therefore, when this woven fabric is applied to clothing, the portion corresponding to the middle stretchable portion is the skin. There is an effect that the adhesiveness with is higher.

  FIG. 3 is a perspective view showing an arm cover or leg cover 300 using the composite stretchable woven fabric of the third embodiment. The arm cover or leg cover 300 includes a high stretchable portion 34, a low stretchable portion 44, and a middle stretchable portion 54 in this order. The boundary surface 60 between the high stretchable portion 34 and the low stretchable portion 44, and the low stretchable portion 44 and the middle stretchable portion. Since the boundary surface 64 with the portion 54 is integrally woven without being sewn, there is no hole or the like generated when the seam is stitched to the portion corresponding to the joint. The low expansion / contraction part 44 has a low expansion / contraction degree compared to the high expansion / contraction part 34 and the middle expansion / contraction part 54, and may be configured to expand or contract at all.

  As a method of forming the composite stretchable woven fabric of the present invention into a cylindrical shape such as the arm cover or leg cover shown in FIG. 3, first, the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are arranged in this order. A sheet of woven fabric is formed as a unit. Thereafter, both side surfaces along with the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are stitched together through scouring, dry heat treatment, water repellent processing, and organizing processing. In order to reinforce the fabric, the portions corresponding to the high stretchable portion 34 and the middle stretchable portion 54 are folded twice and stitched at the boundary surface 60 and the boundary surface 64. Thereby, compared with the arm cover or leg cover manufactured by stitching a plurality of conventional woven fabrics, the stitching process can be reduced, which is advantageous in terms of production cost.

  When the arm cover or leg cover using the composite stretchable woven fabric of the third embodiment is actually attached to the arm or leg, the high stretchable part and the middle stretchable part are easy to fit according to the thickness of the arm or leg, respectively. In addition, there is no discomfort due to pressure due to the difference in stretch between the high stretch portion and the middle stretch portion. In terms of appearance, since the boundary surfaces of the high and low stretchable parts and the low and medium stretchable parts are a series, the seam does not appear in the appearance and is excellent in design. In addition, since the boundary surfaces are connected in series, even when a pattern is applied on a jacquard loom or the like, the pattern can be applied integrally and entirely on the boundary surface.

  As a product using the composite stretchable woven fabric of the present invention, it can be applied not only to the arm cover or the leg cover shown in FIG. For example, in order to give stretchability to the top, top and bottom coveralls that require the fit of the opening, and the like, the clothes with multiple structures, the neck, sleeves, and waist around the T-shirt and sweat In addition, the composite stretchable woven fabric of the present invention can be used, and can also be applied to clothing that requires a predetermined pressure, such as a corset, a stomach wrap, a girdle, or tights. In order to give a predetermined portion a degree of expansion and contraction, it can be applied to any product having partial elasticity by appropriately changing the fiber mixture ratio and fiber type.

  By using the composite stretchable woven fabric of the present invention, the decoration, pattern, etc. of clothing can be obtained in the process of weaving the high stretchable portion, middle stretchable portion, and low stretchable portion in series with a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The effect that it can weave in one at a time is also acquired.

  Hereinafter, embodiments of the composite stretchable woven fabric according to the present invention will be described with reference to the drawings.

Fig.1 (a) is the elements on larger scale which show the woven fabric 100 of the composite elastic | stretch fabric which is a 1st Example.
Fibers 10 having a high contraction resistance and polyurethane 1, 20 fibers low shrinkage property such as polyester, 30 high elasticity portion 40 is low-stretch unit 60 includes the high elasticity portions and low-stretch portion The boundary surface 100 is the composite stretchable woven fabric of the first embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or a dobby loom.
The composite elastic woven fabric 100 is an arm cover, leg cover, coverall with integrated functions such as dust-proof function that requires fitting of the opening, clothing with multiple structures, clothing such as corsets, tights, and T-shirts. A woven fabric that serves as a base of the fabric, and is woven with warp yarn (warp) and weft yarn (weft).

Shrinkage highly fibers 10 are polyurethane, it can substitute fibers having the fiber as well as high shrinkage properties. Shrinkage properties of low fiber 20, polyesters, polyamides (nylons), cupra, cotton, selected wool, acrylic, rayon, hemp, silk, or acetate, etc., from the specified outer fibers (Tencel, lyocell, polylactic acid fibers, etc.) It may substitute fibers having low shrinkage properties as well as the fibers.

High elasticity portion 30 is fiber 20 less the warp of shrinkage properties, constitute a weft in both high fiber 10 of low fiber 20 and contraction of the contraction of allocation of 10 and 20 by the desired yield Chijimido, The hybrid ratio and the selected fiber type of 20 can be changed as appropriate. Weft high elasticity portion, shrinkage properties of low fiber 20 is responsible for covering the high fiber 10 having shrinkage properties. Low-stretch unit 40 constitute both warp and weft in shrinkage having low fiber 20. The boundary surface 60 between the high expansion / contraction part 30 and the low expansion / contraction part 40 is the boundary of the degree of expansion / contraction, and 30 and 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The boundary surface 60 does not have a hole or the like generated when being sewn.

FIG. 1B is a partially enlarged view showing a state 110 after scouring, dry heat treatment, water repellent processing, and rearranging of FIG. 1A in the first embodiment. Scouring, drying, water-repellent, high elasticity portion 32, which is organized processed contracts because it is composed of a high fiber 10 having shrinkage resistance, scouring, dry heat treatment, water-repellent, low-stretch unit organized processed 42 since it is composed of a low fiber 20 having shrinkage properties, and shows a state that does not shrink.

Here, the contents and procedures of scouring, dry heat treatment, water repellent processing, and rearranging will be described below.
(1) Scouring: The woven fabric contains impurities such as glue and oil used when weaving. In this process, the impurities are removed and the dough is placed in hot water at around 75 ° C. in a room heat environment. By this process, impurities such as oil are washed out even if the fabric contains polyurethane fibers that are generally easy to attach oil. In addition, the polyurethane fiber that has been hardened and stretched with glue contracts by the removal of the glue. At this point, the polyurethane fiber is apt to change in terms of stretch and is unstable.
(2) Dry heat (warm air) treatment: In order to remove moisture from the dough whose impurities have been purified by scouring, it is a process of hanging by a machine such as a boiler or drying in the sun (natural drying). The polyurethane fiber containing moisture shrinks further than being dried.
(3) Water repellent treatment: a step of immersing a water repellent liquid composed of a resin or the like at around 40 ° C. twice. As a result, the water repellent is fixed to the surface of the fabric and repels moisture.
(4) Arrangement processing: Drying with hot air at a temperature of about 165 ° C. or more to fix the water repellent liquid. This high-temperature drying step (heat setting) further improves the water repellency, and the polyurethane fibers are further shrunk and fixed to stabilize the stretch.

Scouring, dry heat treatment, water-repellent, by organizing the processing, the difference in yield degree of crimping of the high elasticity portions and low-stretch portion occurs. This difference, or by appropriately changing the mixing ratio of the high shrinkage properties for use in the weft of the high elasticity portion fibers, the type of fibers to be selected as contraction of low fibers used in the weft, the low and high stretch unit difference in yield degree of crimping of the stretchable portion can have a. Also, it is arbitrarily changed the mixing ratio and enables the production of fabric having any desired stretch of the type of fibers to be selected as low shrinkage fibers.

  Further, the scouring, dry heat treatment, water repellent treatment, and rearrangement process make the boundary surface 60 between the high stretchable portion and the low stretchable portion noticeable, but since 60 is not stitched, the boundary surface is continuous without any holes. Connected. Therefore, unlike woven fabrics sewn in the conventional manner, it does not have a hole, so that any substance such as granular, powder, or liquid does not enter from the outside, water repellent effect that repels water, air It is effective in preventing contamination from harmful substances such as radioactive substances contained in dust scattered inside. Moreover, it is not necessary to prepare and sew fabrics having different degrees of stretch, and since there is no trace of stitching on the boundary surface 60, the appearance is excellent in appearance.

  Even in the case of putting a pattern in the woven fabric process, the pattern can be applied continuously and integrally in all the portions having different degrees of stretch as in the present invention. In addition, various patterns such as a check pattern that is applied in a conventional pattern print can be obtained by switching the woven yarn to a series of woven fabrics. In the conventional composite stretch woven fabric obtained by stitching a plurality of woven fabrics having different stretch properties, it is necessary to apply a pattern to each of the plurality of woven fabrics. In this respect, the woven fabric is advantageous in that the number of steps can be reduced, and even a complicated pattern can be easily decorated such as a pattern at a time.

Fig.2 (a) is the elements on larger scale which show the composite elastic woven fabric 200 of the 2nd Example.
Fibers 10 having a high contraction resistance and polyurethane 1, 20 fibers low shrinkage property such as polyester, 30 high elasticity portion 50 is middle extendable unit 62 is the high elasticity portion and the middle stretch unit The boundary surface 200 is the composite stretchable woven fabric of the second embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom.

High elasticity portion 30 is fiber 20 less the warp of shrinkage properties, constitute a weft in both high fiber 10 of low fiber 20 and contraction of the contraction of allocation of 10 and 20 by the desired yield Chijimido, The hybrid ratio can be changed as appropriate. The type of fibers selected from 20 the desired yield Chijimido may be appropriately changed. Medium expansion unit 50 is low stretchability as compared to the high elasticity portion 30, as compared with low-stretch unit 40 refers to the highly stretchable part, high weft low fiber 20 and contraction of the contraction fibers constituted by both 10, allocation of 10 and 20 by the desired yield Chijimido, mixing ratio may be appropriately modified low yield Chijimido than high elasticity portion. The type of fibers selected from 20 the desired yield Chijimido may be appropriately changed. A boundary surface 62 between the high stretchable portion 30 and the middle stretchable portion 50 is a boundary of the stretch degree. Since 30 and 50 are integrally woven, a hole portion or the like generated when sewing is performed on a portion corresponding to a joint. not exist.

FIG. 2B is a partially enlarged view showing a state 210 after scouring, dry heat treatment, water repellent processing, and rearranging processing of FIG. 2A in the second embodiment.

Therefore, when this woven fabric is applied to clothing, the portion corresponding to the middle stretchable portion is the skin. There is an effect that the adhesiveness with is higher.

  FIG. 3 is a perspective view showing an arm cover or leg cover 300 using the composite stretchable woven fabric of the third embodiment. The arm cover or leg cover 300 includes a high stretchable portion 34, a low stretchable portion 44, and a middle stretchable portion 54 in this order. The boundary surface 60 between the high stretchable portion 34 and the low stretchable portion 44, and the low stretchable portion 44 and the middle stretchable portion. Since the boundary surface 64 with the portion 54 is integrally woven without being sewn, there is no hole or the like generated when the seam is stitched to the portion corresponding to the joint. The low expansion / contraction part 44 has a low expansion / contraction degree compared to the high expansion / contraction part 34 and the middle expansion / contraction part 54, and may be configured to expand or contract at all.

  As a method of forming the composite stretchable woven fabric of the present invention into a cylindrical shape such as the arm cover or leg cover shown in FIG. 3, first, the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are arranged in this order. A sheet of woven fabric is formed as a unit. Thereafter, both side surfaces along with the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are stitched together through scouring, dry heat treatment, water repellent processing, and organizing processing. In order to reinforce the fabric, the portions corresponding to the high stretchable portion 34 and the middle stretchable portion 54 are folded twice and stitched at the boundary surface 60 and the boundary surface 64. Thereby, compared with the arm cover or leg cover manufactured by stitching a plurality of conventional woven fabrics, the stitching process can be reduced, which is advantageous in terms of production cost.

  When the arm cover or leg cover using the composite stretchable woven fabric of the third embodiment is actually attached to the arm or leg, the high stretchable part and the middle stretchable part are easy to fit according to the thickness of the arm or leg, respectively. In addition, there is no discomfort due to pressure due to the difference in stretch between the high stretch portion and the middle stretch portion. In terms of appearance, since the boundary surfaces of the high and low stretchable parts and the low and medium stretchable parts are a series, the seam does not appear in the appearance and is excellent in design. In addition, since the boundary surfaces are connected in series, even when a pattern is applied on a jacquard loom or the like, the pattern can be applied integrally and entirely on the boundary surface.

  As a product using the composite stretchable woven fabric of the present invention, it can be applied not only to the arm cover or the leg cover shown in FIG. For example, in order to give stretchability to the top, top and bottom coveralls that require the fit of the opening, and the like, the clothes with multiple structures, the neck, sleeves, and waist around the T-shirt and sweat In addition, the composite stretchable woven fabric of the present invention can be used, and can also be applied to clothing that requires a predetermined pressure, such as a corset, a stomach wrap, a girdle, or tights. In order to give a predetermined portion a degree of expansion and contraction, it can be applied to any product having partial elasticity by appropriately changing the fiber mixture ratio and fiber type.

  By using the composite stretchable woven fabric of the present invention, the decoration, pattern, etc. of clothing can be obtained in the process of weaving the high stretchable portion, middle stretchable portion, and low stretchable portion in series with a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The effect that it can weave in one at a time is also acquired.

  The present invention relates to a composite stretchable woven fabric having a high stretchable portion having high stretchability and a low stretchable portion having low stretchability.

  The clothing has a function of preventing the clothes from slipping down and sticking them to the body by giving stretchability partially. Conventionally, a highly stretchable part and a low stretchable part are manufactured separately and stitched together to form a single woven fabric. In the conventional method by stitching, there are problems such as the thickness due to overlapping stitches, the step of the boundary, the space of the stitching trace due to stitching, and the appearance that the seam appears on the outer surface and the appearance is poor. In addition, there is a problem that uncomfortable feelings such as stuffiness, friction, and touch are caused by the thickness and the stitched portion even when worn.

As a method for producing woven fabrics having different stretchability (composite stretchable woven fabric), for example, there is an arm cover disclosed in Patent Document 1 below.
The arm cover is made of knit, and an opening for passing a finger is provided on the wrist side of the arm cover, and the opening is integrally formed in the process of circular knitting the cylindrical portion.
Moreover, as a manufacturing method of the woven fabric which has high elasticity, there exist a knitted fabric and clothing containing the core-sheath conjugate fiber shown by the following patent document 2, for example.
The knitted fabric and clothing containing this core-sheath conjugate fiber are recycled as synthetic yarns such as polyester, polypropylene, nylon and acrylic as semi-woven yarns, semi-synthetic fibers such as acetate and promix, rayon, polynosic, cupra and lyocell. Natural fibers such as fiber, cotton, hemp, silk, and hair are used. Among them, polyurethane and polystyrene butadiene block copolymers are exemplified as the elastomer resin having stretch elasticity constituting the core portion of the core-sheath conjugate fiber, and polyurethane is particularly suitable.

  Hereinafter, embodiments of the composite stretchable woven fabric according to the present invention will be described with reference to the drawings.

Fig.1 (a) is the elements on larger scale which show the woven fabric 100 of the composite elastic | stretch fabric which is a 1st Example.
In FIG. 1, 10 is a highly stretchable fiber such as polyurethane, 20 is a low stretchable fiber such as polyester, 30 is a high stretchable portion, 40 is a low stretchable portion, and 60 is a boundary surface between a high stretchable portion and a low stretchable portion. , 100 is the composite stretchable woven fabric of the first embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or a dobby loom.
The composite elastic woven fabric 100 is an arm cover, leg cover, coverall with integrated functions such as dust-proof function that requires fitting of the opening, clothing with multiple structures, clothing such as corsets, tights, and T-shirts. A woven fabric that serves as a base of the fabric, and is woven with warp yarn (warp) and weft yarn (weft).

  The highly stretchable fiber 10 is polyurethane, and a fiber having high stretchability can be substituted for this fiber. The low-stretch fiber 20 is selected from polyester, polyamide (nylon), cupra, cotton, wool, acrylic, rayon, hemp, silk, acetate, etc. and non-designated fibers (such as tencel, lyocell, and polylactic acid fiber). Similar to these fibers, fibers having low stretchability can be substituted.

  The high stretchable part 30 is composed of warp yarns 20 having low stretchability and weft yarns composed of both low stretchable fibers 20 and highly stretchable fibers 10. The type of fiber selected can be changed as appropriate. The weft yarn of the high stretch portion plays a role of covering the highly stretchable fiber 10 with the low stretchable fiber 20. The low stretchable part 40 comprises both warps and wefts with fibers 20 having low stretchability. The boundary surface 60 between the high expansion / contraction part 30 and the low expansion / contraction part 40 is the boundary of the degree of expansion / contraction, and 30 and 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The boundary surface 60 does not have a hole or the like generated when being sewn.

  FIG. 1B is a partially enlarged view showing a state 110 after scouring, dry heat treatment, water repellent processing, and rearranging of FIG. 1A in the first embodiment. The highly stretchable portion 32 that has been subjected to scouring, drying, water repellency processing, and organizing processing is contracted because it is composed of the highly elastic fiber 10, and the low stretching portion 42 that has been subjected to scouring, dry heat treatment, water repellency processing, and organizing processing is Since it is composed of the low-stretch fiber 20, it shows a state where it does not shrink.

Here, the contents and procedures of scouring, dry heat treatment, water repellent processing, and rearranging will be described below.
(1) Scouring: The woven fabric contains impurities such as glue and oil used when weaving. In this process, the impurities are removed and the dough is placed in hot water at around 75 ° C. in a room heat environment. By this process, impurities such as oil are washed out even if the fabric contains polyurethane fibers that are generally easy to attach oil. In addition, the polyurethane fiber that has been hardened and stretched with glue contracts by the removal of the glue. At this point, the polyurethane fiber is apt to change in terms of stretch and is unstable.
(2) Dry heat (warm air) treatment: In order to remove moisture from the dough whose impurities have been purified by scouring, it is a process of hanging by a machine such as a boiler or drying in the sun (natural drying). The polyurethane fiber containing moisture shrinks further than being dried.
(3) Water repellent treatment: a step of immersing a water repellent liquid composed of a resin or the like at around 40 ° C. twice. As a result, the water repellent is fixed to the surface of the fabric and repels moisture.
(4) Arrangement processing: Drying with hot air at a temperature of about 165 ° C. or more to fix the water repellent liquid. This high-temperature drying step (heat setting) further improves the water repellency, and the polyurethane fibers are further shrunk and fixed to stabilize the stretch.

  Due to scouring, dry heat treatment, water repellent treatment, and rearrangement, there is a difference in the degree of stretch between the high stretch portion and the low stretch portion. This difference is due to the change in the hybrid ratio of the highly stretchable fibers used in the wefts of the high stretch part and the type of fiber selected as the low stretch fiber used in the wefts. It is possible to make a difference in the degree of stretching. In addition, it is possible to produce a woven fabric having any desired degree of stretch by changing the hybrid ratio arbitrarily or by selecting the type of fiber selected as the low stretch fiber.

  Further, the scouring, dry heat treatment, water repellent treatment, and rearrangement process make the boundary surface 60 between the high stretchable portion and the low stretchable portion noticeable, but since 60 is not stitched, the boundary surface is continuous without any holes. Connected. Therefore, unlike woven fabrics sewn in the conventional manner, it does not have a hole, so that any substance such as granular, powder, or liquid does not enter from the outside, water repellent effect that repels water, air It is effective in preventing contamination from harmful substances such as radioactive substances contained in dust scattered inside. Moreover, it is not necessary to prepare and sew fabrics having different degrees of stretch, and since there is no trace of stitching on the boundary surface 60, the appearance is excellent in appearance.

  Even in the case of putting a pattern in the woven fabric process, the pattern can be applied continuously and integrally in all the portions having different degrees of stretch as in the present invention. In addition, various patterns such as a check pattern that is applied in a conventional pattern print can be obtained by switching the woven yarn to a series of woven fabrics. In the conventional composite stretch woven fabric obtained by stitching a plurality of woven fabrics having different stretch properties, it is necessary to apply a pattern to each of the plurality of woven fabrics. In this respect, the woven fabric is advantageous in that the number of steps can be reduced, and even a complicated pattern can be easily decorated such as a pattern at a time.

Fig.2 (a) is the elements on larger scale which show the composite elastic woven fabric 200 of the 2nd Example.
In FIG. 1, 10 is a highly stretchable fiber such as polyurethane, 20 is a low stretchable fiber such as polyester, 30 is a high stretchable portion, 50 is a middle stretchable portion, 62 is a boundary surface between the high stretchable portion and the middle stretchable portion. , 200 is the composite stretchable woven fabric of the second embodiment. The high stretchable part 30 and the low stretchable part 40 are woven continuously and integrally by a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom.

  The high stretchable part 30 is composed of warps with low stretchable fibers 20 and wefts with both low stretchable fibers 20 and highly stretchable fibers 10. Can be changed. Further, the type of 20 selected fibers can be appropriately changed depending on the desired degree of stretching. The middle stretchable part 50 has a low stretchability compared to the high stretchable part 30 and refers to a part having a high stretchability compared to the low stretchable part 40, and the weft is made of the low stretchable fiber 20 and the highly stretchable fiber 10. Both are configured, and the distribution of 10 and 20 and the hybrid ratio can be changed as appropriate at a lower stretch degree than that of the high stretch part, depending on the desired stretch degree. Further, the type of 20 selected fibers can be appropriately changed depending on the desired degree of stretching. A boundary surface 62 between the high stretchable portion 30 and the middle stretchable portion 50 is a boundary of the stretch degree. Since 30 and 50 are integrally woven, a hole portion or the like generated when sewing is performed on a portion corresponding to a joint. not exist.

  FIG. 2B is a partially enlarged view showing a state 210 after scouring, dry heat treatment, water repellent processing, and rearranging processing of FIG. 2A in the second embodiment. The highly stretchable portion 32 that has been subjected to scouring, dry heat treatment, water repellent processing, and rearrangement is made of the highly stretchable fiber 10 and thus contracts, and the middle stretchable portion 52 that has been subjected to scouring, dry heat treatment, water repellent processing, and rearrangement processing. Since the structure also includes the highly stretchable fiber 10, it contracts with a moderate degree of stretch as compared with the high stretch portion 32.

  In the second embodiment, the middle stretchable portion is stretchable compared to the low stretchable portion of the first embodiment. Therefore, when this woven fabric is applied to clothing, the portion corresponding to the middle stretchable portion is the skin. There is an effect that the adhesiveness with is higher.

  FIG. 3 is a perspective view showing an arm cover or leg cover 300 using the composite stretchable woven fabric of the third embodiment. The arm cover or leg cover 300 includes a high stretchable portion 34, a low stretchable portion 44, and a middle stretchable portion 54 in this order. The boundary surface 60 between the high stretchable portion 34 and the low stretchable portion 44, and the low stretchable portion 44 and the middle stretchable portion. Since the boundary surface 64 with the portion 54 is integrally woven without being sewn, there is no hole or the like generated when the seam is stitched to the portion corresponding to the joint. The low expansion / contraction part 44 has a low expansion / contraction degree compared to the high expansion / contraction part 34 and the middle expansion / contraction part 54, and may be configured to expand or contract at all.

  As a method of forming the composite stretchable woven fabric of the present invention into a cylindrical shape such as the arm cover or leg cover shown in FIG. 3, first, the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are arranged in this order. A sheet of woven fabric is formed as a unit. Thereafter, both side surfaces along with the high stretchable portion 34, the low stretchable portion 44, and the middle stretchable portion 54 are stitched together through scouring, dry heat treatment, water repellent processing, and organizing processing. In order to reinforce the fabric, the portions corresponding to the high stretchable portion 34 and the middle stretchable portion 54 are folded twice and stitched at the boundary surface 60 and the boundary surface 64. Thereby, compared with the arm cover or leg cover manufactured by stitching a plurality of conventional woven fabrics, the stitching process can be reduced, which is advantageous in terms of production cost.

  When the arm cover or leg cover using the composite stretchable woven fabric of the third embodiment is actually attached to the arm or leg, the high stretchable part and the middle stretchable part are easy to fit according to the thickness of the arm or leg, respectively. In addition, there is no discomfort due to pressure due to the difference in stretch between the high stretch portion and the middle stretch portion. In terms of appearance, since the boundary surfaces of the high and low stretchable parts and the low and medium stretchable parts are a series, the seam does not appear in the appearance and is excellent in design. In addition, since the boundary surfaces are connected in series, even when a pattern is applied on a jacquard loom or the like, the pattern can be applied integrally and entirely on the boundary surface.

  As a product using the composite stretchable woven fabric of the present invention, it can be applied not only to the arm cover or the leg cover shown in FIG. For example, in order to give stretchability to the top, top and bottom coveralls that require the fit of the opening, and the like, the clothes with multiple structures, the neck, sleeves, and waist around the T-shirt and sweat In addition, the composite stretchable woven fabric of the present invention can be used, and can also be applied to clothing that requires a predetermined pressure, such as a corset, a stomach wrap, a girdle, or tights. In order to give a predetermined portion a degree of expansion and contraction, it can be applied to any product having partial elasticity by appropriately changing the fiber mixture ratio and fiber type.

  By using the composite stretchable woven fabric of the present invention, the decoration, pattern, etc. of clothing can be obtained in the process of weaving the high stretchable portion, middle stretchable portion, and low stretchable portion in series with a woven fabric manufacturing apparatus such as a jacquard loom or dobby loom. The effect that it can weave in one at a time is also acquired.
