Description

Technical Field

[0001] The present invention relates to a fabric.

Background Art

[0002] Proposals for fixing and correcting the body using fiber products are already known. In Patent Document 1, a lumbar support belt using a stretchable fabric is disclosed. In Patent Document 2, a seat belt webbing that uses monofilaments for the weft yarns to improve the lateral rigidity and suppress the breakage of the weft yarns due to the impact of an accident is disclosed. Patent Document 3 describes an invention related to a corrective device, and it is described that in the corrective device, a belt-like fabric structure having a function of generating a corrective force at the corrective site when worn is used. By using a fiber woven fabric that is more flexible than metal or plastic materials in this way, it is possible to follow and fix the movement and form of the body. However, for the correction of parts of the body that require a high corrective force, such as the lower limbs, the development of a material having appropriate elongation characteristics under high stress is desired.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, while conventional elastic materials such as rubber bands can follow some foot movement, they do not provide sufficient fixation to the corrective area, and the necessary corrective force cannot be obtained. Furthermore, materials like those described in Patent Document 2 have a certain degree of rigidity and flexibility, but they lack elasticity in the longitudinal direction, and cannot follow the body's movement during correction, resulting in pain due to friction with the skin. In addition, the woven structure specifically described in Patent Document 3 uses the weft direction of the woven structure as the longitudinal direction of the strip, requiring processing from the woven fabric into a strip. When processing the woven fabric into a strip, from a productivity standpoint, if wide woven fabrics are cut by heat, the molten resin of the fibers can become burrs that rub against the skin, potentially causing pain, and there was room for improvement.

[0005] Therefore, the objective of the present invention is to provide a fabric that combines corrective force for the body and adaptability to movement, while also being comfortable against the skin. [Means for solving the problem]

[0006] The present invention aims to achieve the above objective and has the following configuration.

[0007] (1) A fabric in which yarns parallel to the longitudinal direction contain a polyester elastomer, and yarns parallel to the width direction are folded back at at least one width end of the fabric, and the elongation rate in the direction of the load when a 100N / 50mm load is applied to the longitudinal direction of the fabric is 1.0% or more and 20.0% or less, and the width is 30mm or more and 200mm or less.

[0008] (2) The fabric according to (1), wherein the threads parallel to the width direction are folded back at one width end of the fabric and the other width end includes entangled threads.

[0009] (3) The fabric according to (1) or (2) above, wherein the fineness of the yarn containing the polyester elastomer is 2000 dtex or more and 2500 dtex or less.

[0010] (4) The fabric according to any one of (1) to (3) above, wherein the yarns parallel to the width direction are 1500 dtex or more and 2000 dtex or less.

[0011] (5) The fabric according to any of (2) to (4) above, wherein the entangled yarn is 150 dtex or more and 350 dtex or less.

[0012] (6) The fabric according to any one of (1) to (5) above, wherein the yarn parallel to the width direction includes an inelastic yarn.

[0013] (7) The fabric according to any one of (1) to (6) above, wherein the yarn parallel to the longitudinal direction is a core-sheath type yarn, the sheath component mainly consists of a polyester elastomer, and the core component mainly consists of polyethylene terephthalate.

[0014] (8) A woven fabric according to any of (1) to (7) above, wherein the stretch recovery rate after stretching 50 times with a load of 100 N / 50 mm in the longitudinal direction is 60% or more and 100% or less. [Effects of the Invention]

[0015] This invention makes it possible to provide a fabric that has stretch characteristics suitable for correcting the body, combines corrective force with the ability to follow movement, and has a pleasant feel against the skin.

[0016] The textile of the present invention is particularly suitable for fibrous orthotic devices and orthotic belts for orthotic devices, and can be suitably used for therapeutic and rehabilitative upper limb orthoses, trunk orthoses, and lower limb orthoses aimed at preventing physical deformities, improving function, and enhancing daily living activities, but its scope of application is not limited to these. [Brief explanation of the drawing]

[0017] [Figure 1] Figure 1 is a conceptual diagram showing a fiber-based clubfoot correction device fabricated in the example. [Modes for carrying out the invention]

[0018] The fabric of the present invention contains polyester-based elastomer in the yarns parallel to the longitudinal direction. By containing the polyester-based elastomer, appropriate extensibility and resilience can be imparted to the fabric in the longitudinal direction.

[0019] In the above case, the usage ratio of the yarns parallel to the longitudinal direction containing the polyester-based elastomer is appropriately determined within the range where the desired properties can be obtained. However, it is preferably 50% by mass or more and 100% by mass or less based on the total yarns parallel to the longitudinal direction of the fabric.

[0020] The polyester-based elastomer is preferably a block copolymer of an aromatic polyester and a polyoxyalkylene glycol using an aromatic dicarboxylic acid and a glycol as main raw materials in order to obtain the strength necessary for body correction and the resilience after elongation as a stretch fabric. Furthermore, due to its good resilience after elongation, a copolymer of polybutylene terephthalate and polytetramethylene glycol is more preferably used.

[0021] As such a polyester-based elastomer, commercially available products such as "Hytrel" (registered trademark) manufactured by Toray DuPont can be used.

[0022] In the present invention, it is preferable that the yarns parallel to the longitudinal direction are core-sheath type yarns containing a polyester-based elastomer. Among them, it is preferable that the sheath component is mainly composed of a polyester-based elastomer and the core component is mainly composed of polyethylene terephthalate.

[0023] By containing polyethylene terephthalate having no rubber elasticity as the core component, the rubber elasticity in the longitudinal direction of the fabric can be deliberately reduced, and as a result, stretch characteristics more suitable for body correction can be imparted. In the above, the "main component" refers to the component with the largest amount among the constituent components, and is preferably 50% by mass or more, more preferably 80% by mass or more, and most preferably 100% by mass from the viewpoint of controlling the rubber elasticity in the longitudinal direction of the fabric.

[0024] In the cross-section of the yarn, the ratio of core to sheath area is preferably 3% to 50%, and more preferably 5% to 20%. Furthermore, it is preferable that the yarn parallel to the longitudinal direction has fewer filaments, and more preferably is monofilament. By using monofilament, the contact area between yarns at the weave intersections is reduced, resulting in good elasticity recovery, i.e., followability.

[0025] Furthermore, it is preferable that the fabric of the present invention contains non-elastic yarns parallel to the width direction. By including non-elastic yarns parallel to the width direction, the elasticity of the fabric in the longitudinal and bias directions can be deliberately reduced, resulting in stretchability that is more suitable for body correction. The term "non-elastic yarn" here refers to yarns other than elastic yarns, and preferably includes yarns composed of polyethylene terephthalate, polybutylene terephthalate, polypropylene terephthalate or copolymers thereof, polyamides, etc., or metal fibers, but yarns that have heat-setting properties are preferably used. Here, "composed of" means that the polymer is included as the main component, but other components such as various additives may also be included.

[0026] In the above case, the proportion of non-elastic yarn used is determined appropriately within the range in which the desired properties can be obtained, but it is preferable that the total amount of yarn parallel to the width direction of the fabric be between 50% and 100% by mass.

[0027] The fabric of the present invention has threads parallel to the width direction folded back at at least one width edge of the fabric. Threads parallel to the width direction may be folded back at both width edges of the fabric. Here, "folded back" means that when threads parallel to the width direction, such as weft threads, are interwoven with threads parallel to the longitudinal direction during weaving, they are simply folded back as weft threads without any edge treatment such as cutting or weaving with entanglement threads at the width edge. When the threads are folded back at only one width edge of the fabric, it is preferable that the other width edge be constructed so that the threads parallel to the width direction do not protrude outside the weave structure of the fabric by weaving with entanglement threads. With the above configuration, it is not necessary to melt the width edges of the fabric with heat or ultrasound, and when used for body correction, the risk of abrasion to the body due to frayed threads or burrs can be reduced. To achieve the above configuration, it is preferable to weave using a shuttle loom or a needle loom.

[0028] In particular, a fabric in which threads parallel to the width direction are folded back on one side and entangled threads are included at the other width end is more preferable because it improves weaving speed and productivity. Furthermore, the threads used for the entangled threads may be either spun yarns composed of short fibers or filamentous fibers, as long as they meet the range defined in this invention. In terms of the material of the threads, there are no limitations on natural fibers, synthetic fibers, etc., as long as they meet the range defined in this invention, and various fibers can be used. However, it is preferable from the viewpoint of appearance and dyeability to use the same material as the threads parallel to the length direction or the threads parallel to the width direction.

[0029] In the present invention, the fineness of the yarn containing the polyester elastomer is preferably 2000 dtex or more and 2500 dtex or less. A fineness of 2000 dtex or more provides excellent strength to the fabric, resulting in a moderate thickness and firmness, and excellent corrective force and application comfort. A fineness of 2500 dtex or less provides excellent flexibility to the fabric, resulting in excellent wearability without stiffness when used for body correction, or a more preferable range for elongation under a desired load. A fineness of 2100 dtex or more and 2400 dtex or less is more preferable.

[0030] In the present invention, it is preferable that the yarns parallel to the width direction have a fineness of 1500 dtex or more and 2000 dtex or less. Having yarns parallel to the width direction of 1500 dtex or more provides excellent strength to the fabric, similar to the polyester elastomer, and gives the fabric an appropriate thickness and firmness, resulting in excellent corrective force and application comfort. Having yarns parallel to the width direction of 2000 dtex or less provides excellent flexibility to the fabric, resulting in excellent wearing comfort without stiffness when used for body correction, etc. It is more preferable that the fineness of the yarns parallel to the width direction be 1600 dtex or more and 1900 dtex or less.

[0031] In the fabric of the present invention, when entangled yarn is used, it is preferable that the entangled yarn is between 150 dtex and 350 dtex. Having entangled yarn of 150 dtex or more provides excellent fabric strength, while having it at 350 dtex or less allows for a more appropriate yarn restraint force at the edges, resulting in a superior appearance without puckering or other cosmetic defects in the woven fabric. The fineness of the entangled yarn is more preferably between 180 dtex and 300 dtex.

[0032] Furthermore, the elongation rate in the longitudinal direction of the fabric when a 100N / 50mm load is applied is 1.0% to 20.0%. A rate of 1.5% to 10.0% is more preferable. By setting the elongation rate to 1.0% or higher, when used for body correction, the fabric stretches appropriately without excessively fixing the area to be corrected, thereby reducing friction between the area to be corrected and the corrective device. This improves the ability to follow the movement of the area to be corrected during movement and the pressure on the body that occurs when corrective force is applied, suppressing pain and discomfort when worn. In addition, when the fabric is applied by the wearer during movement, it becomes easier to move the muscles, which is effective in functional recovery and improving daily movements. Furthermore, by setting the elongation rate to 20.0% or lower, the fabric stops stretching appropriately, allowing for body correction.

[0033] The weave structure of the aforementioned fabric is not particularly limited as long as it satisfies the scope defined in this invention, but plain weave, twill weave, satin weave, and double weave, which combines these structures, can be appropriately selected depending on the application.

[0034] Furthermore, the fabric of the present invention preferably has a cover factor of 800 to 2000 for yarns parallel to the longitudinal direction. A cover factor of 800 or more provides excellent fabric strength, and a cover factor of 2000 or less provides excellent productivity in the weaving process. More preferably, it is 1200 to 1800. Furthermore, the cover factor of yarns parallel to the width direction preferably is 1400 to 3000. A cover factor of 1400 or more provides excellent fabric strength, and a cover factor of 3000 or less provides an even more appropriate range for the elongation in the longitudinal direction of the fabric. More preferably, it is 1500 to 2100.

[0035] Here, the cover factor is a value calculated as follows. Note that, in principle, the cover factor of the above-mentioned fabric is calculated based on the weave density and fineness of the constituent yarns of the finished fabric after post-processing of the raw fabric. However, for convenience, it may also be calculated based on the fineness of the raw yarn used (however, if it is not clear from common technical knowledge that the fineness of either the raw yarn or the constituent yarns before weaving falls within the above range, the measurement should be carried out in accordance with the principle). Furthermore, the examples and comparative examples described later were calculated based on the weave density and fineness of the finished product.

[0036] (Coverage Factor) = (Density: threads / 2.54cm) × (Fineness: (9 / 10) × Fineness (dtex)) 1 / 2 .

[0037] Furthermore, the fabric of the present invention has a width of 30 mm or more and 200 mm or less. If the width is less than 30 mm, the strength of the fabric will be insufficient. Alternatively, when used for body correction, the contact surface with the body will be reduced, and because the fabric has a relatively low elongation rate in the longitudinal direction, it tends to dig into the skin, reducing wearing comfort. Also, if the width is greater than 200 mm, because the fabric has a relatively low elongation rate in the longitudinal direction, when used for body correction, the fabric tends to become stiff, reducing wearing comfort. It is more preferable that the fabric of the present invention has a width of 40 mm or more and 100 mm or less.

[0038] The fabric of the present invention preferably has a stretch recovery rate of 60% to 100% after being stretched 50 times with a load of 100N / 50mm in the longitudinal direction, and more preferably 80% to 100%. Setting the stretch recovery rate after 50 stretches within the above range is preferable because, when used for body correction, the force that returns the fabric to its original corrected position is appropriately applied in response to the force applied by the wearer, thus maintaining the appropriate corrected position and being effective in functional recovery and improving daily movements. In addition, the appropriate fixing and corrective force is maintained for a long period, allowing the corrective device of the present invention to be used continuously, further enhancing its effectiveness in functional recovery and improving daily movements. Methods for achieving a stretch recovery rate of 60% to 100% include using yarn containing polyester elastomer in the longitudinal direction of the fabric.

[0039] The resulting textile of the present invention combines corrective force for the body with flexibility to follow movement and has a pleasant feel against the skin, making it suitable for use in corrective belts for textile corrective devices and orthotics (especially anchor members (for example, members that act as fulcrums for applying corrective force in the corrective direction) and corrective members used to apply corrective force in the corrective direction). In particular, it is suitable for use in orthotic devices such as upper limb orthoses, trunk orthoses, and lower limb orthoses for therapeutic and rehabilitative purposes aimed at preventing bodily deformities, improving function, and enhancing daily living activities, but its scope of application is not limited to these. [Examples]

[0040] Next, the textile of the present invention will be described based on examples. The method for measuring the properties used in the examples is as follows.

[0041] (1) Fineness Fineness was measured according to JIS L 1013:2010 8.3.1 Correct fineness (Method B).

[0042] (2) Fabric width Using a ruler, five arbitrary points were measured along the width of the fabric, and the average of these measurements was used to determine the value.

[0043] (3) Elongation rate when loaded at 100N / 50mm Five test specimens, each measuring 50 mm in width and 300 mm in length, were taken from the fabric. A constant-speed elongation tensile testing machine with an automatic recording device was used, with a grip spacing of 200 mm. The test specimens were fixed to the grips, removing any slack or tension. The specimens were stretched at a tensile speed of 200 mm / min until a load of 150 N was reached. Based on the load deformation curve obtained from the measurements, the displacement at 100 N was measured, and the elongation rate L (%) was calculated using the following formula and expressed as the average of the five specimens.

[0044] Elongation rate L(%)=(L1 / L)×100 L: Gripping distance (mm) L1: Displacement (mm) when stretched to 100N Furthermore, if the width of the fabric was less than 50 mm, the load was calculated by converting the load from the fabric width to 100 N / 50 mm and then measuring and calculating it.

[0045] (4) Elongation recovery rate Five test specimens measuring 50 mm in width and 300 mm in length were taken. Using a constant-speed elongation tensile testing machine with an automatic recording device, marks were made at a gripping distance of 200 m (Ld), and the specimens were fixed to the grips after removing any slack or tension. The specimens were stretched to 100 N at a tensile speed of 200 mm / min, left for 1 minute, then returned to their original position at the same speed and left for 3 minutes. After repeating this operation 50 times, the load was removed, left for 3 minutes, and after removing any slack or tension from the specimens, the length between the marks (Ld1) was measured, and the elongation recovery rate LD (%) was calculated using the following formula and expressed as the average of the five specimens. Elongation recovery rate LD(%)=[Ld-(Ld1-Ld) / Ld]×100 Furthermore, if the width of the fabric was less than 50 mm, the load was calculated by converting the load from the fabric width to 100 N / 50 mm and then measuring and calculating it.

[0046] (5) Weaving density Measurements were taken according to JIS L 1096:2010 8.6.1 (Method A). The sample was placed on a flat surface, and after removing any unnatural wrinkles or tension, the number of warp and weft threads per inch (2.54 cm) was counted at five different locations, and the average value for each was calculated.

[0047] (6) Wear evaluation A fibrous clubfoot correction device, as shown in Figure 1, was fabricated using the fabric of the present invention. Figure 1 is a conceptual diagram showing the fibrous clubfoot correction device fabricated in the embodiment. Unless otherwise specified, the width edges in the width direction (perpendicular to the longitudinal direction) were not cut, and the device was used as anchor member A1 and anchor member B3 and correction member 2 as shown in Figure 1, with the aim of applying a corrective force in the correction direction 4. In this case, the longitudinal direction of the fabric was used as the longitudinal direction of each member. This clubfoot correction device was worn on one foot of a clubfoot patient requiring correction, and the device was evaluated for three items: clubfoot correction force, wearing comfort, and conformability, after walking for one hour. Clubfoot correction force was evaluated by a professional third party observing the wearer's walking state, and wearing comfort and conformability were evaluated by the wearer's sensory evaluation, all of which were evaluated on a four-point scale: ◎, ○, △, ×.

[0048] A. Varus correction force ◎: The inversion is corrected more effectively than when not wearing the corrective device, and the player walks with both the outer and inner edges of the sole touching the ground upon landing.

[0049] ○: There is slight inversion of the foot while walking, but the inversion is corrected compared to when not wearing the corrective device, and the foot now touches the ground with both the outer and inner edges of the sole upon landing.

[0050] △: There is a certain degree of foot inversion during walking, but the inversion has improved compared to when the corrective device was not worn, and walking is more stable.

[0051] ×: There is no difference in the inversion of the foot compared to when the corrective device is not worn, the inversion of the foot cannot be corrected, and the outer edge of the sole touches the ground when landing, resulting in an unstable gait.

[0052] B. Wearing comfort ◎: No discomfort while walking.

[0053] ○: I feel a slight discomfort while walking.

[0054] △: There is some discomfort while walking, but it is possible to continue wearing it.

[0055] ×: I experienced discomfort while walking and was unable to continue wearing it.

[0056] In addition, for cases marked with a triangle (△) or lower, details of the perceived discomfort are also included.

[0057] C. Followability ◎: It follows walking motions well.

[0058] ○: Generally follows walking motion.

[0059] △: It follows walking movements, but there are times when it cannot follow them perfectly.

[0060] ×: Unable to follow walking movements.

[0061] Hereinafter, Examples 9 and 10 shall be interpreted as corresponding to Reference Examples 1 and 2, respectively. (Example 1) Using polyethylene terephthalate as the core component and poly(butylene glycol / polytetramethylene ether glycol) terephthalate (Toray DuPont's "Hytrel" (registered trademark)) as the sheath component, a 2200 dtex core-sheath monofilament with a cross-sectional area ratio of core:sheath = 10:90 was used as the warp thread. For the weft thread, a 1670 dtex-144 filament polyethylene terephthalate (Toray's high-strength polyester) fiber was used, loosely twisted at 70 T / m. Furthermore, a 220 dtex-72 filament polyethylene terephthalate fiber was used as the entanglement thread. Using a needle loom, a 2 / 2 twill fabric was produced with a warp density of 30 threads / 2.54 cm and a weft density of 42 threads / 2.54 cm, where one end of the weft thread was folded back and the other end was woven in with the entanglement thread. The resulting fabric was heat-treated at 170°C for 2 minutes under conditions that prevent the threads from fusing together, and then scouring in a continuous scouring machine to obtain the properties shown in Table 1.

Although the corrective force was slightly inferior, it was suitable for use in correcting the body.

[0067] (Example 7) A fabric was obtained in the same manner as in Example 1, except that the weft yarn was a 1670 dtex-144 filament multifilament consisting solely of poly(butylene glycol / polytetramethylene ether glycol) terephthalate (Toray DuPont's "Hytrel" (registered trademark)) (elastic yarn). The properties, physical properties, and wear evaluation results of the obtained fabric are shown in Table 1.

The properties, physical properties, and wear evaluation results of the obtained fabric are shown in Table 1. Although it was slightly inferior in corrective force and wearing comfort, it was suitable for use in correcting the body.
