  ADVANTAGE OF THE INVENTION According to this invention, it is clothing provided with a motion sensor, Comprising: Three-dimensional attitude | position information can be detected accurately and the clothing excellent in wearing comfort is obtained.

  Hereinafter, embodiments of the present invention will be described in detail. First, the present invention is a garment including a motion sensor, and includes a fabric having a stretchability of 20 to 250% in at least one of a horizontal direction and a vertical direction.

  Here, the fabric preferably includes crimped fibers having a torque of 30 T / m or less. The crimped fiber having a torque of 30 T / m or less (hereinafter sometimes simply referred to as “crimped fiber”) includes two or more types of false twisted crimped yarns that differ from each other in terms of production conditions or fineness (preferably The composite yarn is preferably composed of only two or more false twisted crimped yarns that differ from each other in production conditions or fineness.

  Torque is reduced by setting the false twist in the first heater zone to the false twist crimped yarn, so-called one heater false twist crimped yarn, and further introducing the yarn into the second heater zone and subjecting it to relaxation heat treatment. In addition, there is a so-called second heater false twist crimped yarn. Further, depending on the direction of twisting, there are a false twist crimped yarn having a torque in the S direction and a false twist crimped yarn having a torque in the Z direction. In the present invention, these false twist crimped yarns can be used. In particular, it is preferable to form a composite yarn with a false twist crimped yarn having a torque in the S direction and a false twist crimped yarn having a torque in the Z direction because a low torque composite yarn can be obtained.

Such a composite yarn can be produced, for example, by the following method. That is, a one-heater false-twist crimped yarn is obtained by twisting the yarn with a twisting device via a first roller and a heat treatment heater having a set temperature of 90 to 220 ° C. (more preferably 100 to 190 ° C.). It may be obtained, or a second heater false twisted crimped yarn may be obtained by introducing it into the second heater zone and subjecting it to a relaxation heat treatment if necessary. The draw ratio during false twisting is preferably in the range of 0.8 to 1.5, and the false twist number is the formula of false twist number (T / m) = (32500 / (Dtex) ^1/2 ) × α. α = 0.5 to 1.5 is preferable, and usually 0.8 to 1.2. However, Dtex is the total fineness of the yarn. As the twisting device to be used, a disk-type or belt-type friction type twisting device is suitable because it is easy to thread and there is little yarn breakage, but a pin-type twisting device may also be used. Further, depending on the direction of twisting, the torque of the false twist crimped yarn can be selected from the S direction or the Z direction. Next, the composite yarn is obtained by combining two or more types of false twist crimped yarn.

  It is preferable that the composite yarn is entangled by interlace processing. The number of entanglements (interlaces) is preferably in the range of 30 to 90 / m in order not to impair the soft texture and stretchability. If the number is greater than 90 / m, the soft texture and stretchability may be impaired. On the other hand, when the number is less than 30 / m, the converging property of the composite yarn becomes insufficient, and the knitting property may be impaired. In addition, the entanglement process (interlace process) may be performed using a normal interlace nozzle.

  The torque of the composite yarn thus obtained is preferably 30 T / m or less (preferably 18 T / m or less, more preferably 10 T / m or less, particularly preferably non-torque (0 T / m)). The torque is preferably as small as possible, and most preferably non-torque (0 T / m). In order to achieve non-torque in this way, when the false twisted crimped yarn having the torque in the S direction and the false twisted crimped yarn in the Z direction are combined, they have the same torque except that the direction of the torque is different. Two types of false twist crimped yarn may be used.

  In the composite yarn (crimped fiber), the crimp rate is preferably 2% or more (more preferably 10 to 20%). If the crimp ratio is less than 2%, there is a possibility that sufficient soft texture and stretchability cannot be obtained.

  The composite yarn (crimped fibers) preferably has a single fiber fineness of 2.3 dtex or less (preferably 0.00002 to 2.0 dtex, particularly preferably 0.1 to 2.0 dtex). The smaller the fiber yarn fineness, the better, and the single yarn fiber diameter called nanofiber may be 1000 nm or less. When the single fiber fineness is larger than 2.3 dtex, the water absorption is lowered, and there is a possibility that the rate of change in air permeability when wet is lowered. The total fineness of the composite yarn is preferably in the range of 33 to 220 dtex. Furthermore, the number of filaments of the composite yarn is preferably in the range of 50 to 300 (more preferably 100 to 300).

  In addition, the single yarn cross-sectional shape of the composite yarn (crimped fiber) may be a normal round cross-section, or may be an irregular cross-sectional shape other than the round cross-section. Examples of such irregular cross-sectional shapes include triangles, squares, crosses, flats, flats with constrictions, H-types, and W-types. At that time, the cross-sectional flatness expressed by the ratio B / C1 of the flat cross-sectional shape with the length B in the longitudinal centerline direction to the maximum width C1 in the direction perpendicular to the longitudinal centerline direction is 2 It is preferable in terms of the softness of the fabric to be in the range of ˜6 (more preferably 3.1 to 5.0). In addition, the water absorption of the fabric is such that the ratio C1 / C2 of the maximum value C1 of the width to the minimum value C2 is in the range of 1.05 to 4.00 (more preferably 1.1 to 1.5). From the viewpoint of sex.

  The fibers constituting the crimped fibers are not particularly limited, and polyester fibers, acrylic fibers, nylon fibers, rayon fibers, acetate fibers, and natural fibers such as cotton, wool, silk, and composites thereof are used. Is possible. Polyester fibers are particularly preferable.

  As such polyester, terephthalic acid is the main acid component, and alkylene glycol having 2 to 6 carbon atoms, that is, at least one selected from the group consisting of ethylene glycol, trimethylene glycol, tetramethylene glycol, pentamethylene glycol and hexamethylene glycol. Polyesters with seeds as the main glycol component are preferred. Of these, polyester (polyethylene terephthalate) containing ethylene glycol as the main glycol component or polyester (polytrimethylene terephthalate) containing trimethylene glycol as the main glycol component is particularly preferable.

  Such a polyester may have a small amount (usually 30 mol% or less) of a copolymer component as required. In this case, examples of the bifunctional carboxylic acid other than terephthalic acid used include isophthalic acid, naphthalene dicarboxylic acid, diphenyldicarboxylic acid, diphenoxyethanedicarboxylic acid, β-hydroxyethoxybenzoic acid, p-oxybenzoic acid, 5 -Aromatic, aliphatic, and alicyclic bifunctional carboxylic acids such as sodium sulfoisophthalic acid, adipic acid, sebacic acid, and 1,4-cyclohexanedicarboxylic acid. Examples of the diol compound other than the glycol include aliphatic, alicyclic and aromatic diol compounds such as cyclohexane-1,4-dimethanol, neopentyl glycol, bisphenol A and bisphenol S, and polyoxyalkylene glycol. Can give.

  The polyester may be synthesized by any method. For example, in the case of polyethylene terephthalate, terephthalic acid and ethylene glycol are directly esterified, or a lower alkyl ester of terephthalic acid such as dimethyl terephthalate is transesterified with ethylene glycol, or terephthalic acid and ethylene oxide are used. And the first stage reaction to produce a glycol ester of terephthalic acid and / or its low polymer, and the first stage reaction product is heated under reduced pressure until the desired degree of polymerization is reached. It may be produced by a second stage reaction for condensation reaction. The polyester is a material-recycled or chemical-recycled polyester, or a catalyst containing a specific phosphorus compound and a titanium compound as described in JP-A-2004-270097 and JP-A-2004-212268. Polyester obtained by using may be used. Further, it may be a biodegradable polyester such as polylactic acid or stereocomplex polylactic acid.

  When the ultraviolet absorbent is contained in the polyester in an amount of 0.1% by weight or more (preferably 0.1 to 5.0% by weight) relative to the weight of the polyester, it is preferable because ultraviolet shielding is added to the fabric. Examples of such UV absorbers include benzoxazine-based organic UV absorbers, benzophenone-based organic UV absorbers, benzotriazole-based organic UV absorbers, and salicylic acid-based organic UV absorbers. Of these, benzoxazine-based organic ultraviolet absorbers are particularly preferred because they do not decompose at the spinning stage.

  Suitable examples of such benzoxazine-based organic ultraviolet absorbers are those disclosed in JP-A-62-1744. That is, 2-methyl-3,1-benzoxazin-4-one, 2-butyl-3,1-benzoxazin-4-one, 2-phenyl-3,1-benzoxazin-4-one, 2,2 '-Ethylenebis (3,1-benzoxazin-4-one), 2,2'-tetramethylenebis (3,1-benzoxazin-4-one), 2,2'-p-phenylenebis (3 1-benzoxazin-4-one), 1,3,5-tri (3,1-benzoxazin-4-one-2-yl) benzene, 1,3,5-tri (3,1-benzoxazine- 4-on-2-yl) naphthalene and the like.

  Further, when the matting agent (titanium dioxide) is contained in the polyester in an amount of 0.2% by weight or more (preferably 0.3 to 2.0% by weight) relative to the weight of the polyester, it is preferable because the cloth has anti-permeability. .

  In addition, the polyester may contain fine pore forming agents (organic sulfonic acid metal salts), anti-coloring agents, heat stabilizers, flame retardants (antimony trioxide), fluorescent whitening agents, coloring pigments, antistatic agents, if necessary. One or more of an agent (metal sulfonate), a hygroscopic agent (polyoxyalkylene glycol), an antibacterial agent, and other inorganic particles may be included.

  In the garment of the present invention, the garment preferably includes a fabric, and the fabric preferably includes the crimped fiber. It is important that the stretch property of at least one of the horizontal direction and the vertical direction of the fabric is 2 to 250% (preferably 60 to 100%, more preferably 80 to 100%). If the stretchability is less than 20% in both the horizontal and vertical directions, the change in the adhesion between the motion sensor and the body will increase when the body is moved, and displacement of the motion sensor will occur, resulting in 3D posture information. There is a possibility that the detection accuracy is lowered.

  In that case, the structure of the fabric is not particularly limited, and may be a knitted fabric, a woven fabric, or a nonwoven fabric. For example, woven fabrics having a woven structure such as plain weave, twill weave, satin, knitted fabrics having a knitted structure such as tengu, smooth, milling, kanoko, knitting yarn, denby, half, and non-woven fabric are preferably exemplified. It is not limited to. The number of layers may be a single layer or a multilayer of two or more layers. Of these, a knitted fabric is preferable. In particular, a knitted fabric having a weft knitted (round knitted) structure is preferable.

Moreover, it is preferable that the knitted fabric is subjected to water absorption processing. By subjecting the fabric to water absorption, the sweat-absorbing property of the garment containing the fabric is improved, and excellent wearing comfort is obtained. Moreover, it is preferable that the fabric weight of the said knitted fabric exists in the range of 70-250 g / m < ² >. If the basis weight is less than 70 g / m ² , the water absorption may be lowered. On the other hand, if the basis weight is larger than 250 g / m ² , the weight of the garment becomes heavy and the wearing comfort may be reduced.

  Moreover, it is preferable that the textile fabric containing the ultra fine fiber whose fiber diameter is 50-3000 nm is laminated | stacked on the single side | surface of the said knitted fabric. When such a woven fabric is laminated, the adhesion between the woven fabric and the skin is improved, the motion sensor is securely fixed, and excellent three-dimensional posture information detection accuracy is obtained. In addition, the said ultrafine fiber can be manufactured by the method as described in patent 4473867, for example. As commercial products, “Nanofront” (registered trademark) manufactured by Teijin Limited is exemplified.

The garment of the present invention is obtained by knitting and weaving the crimped fiber by a conventional method to obtain a fabric, sewing the garment using the fabric, and then attaching a motion sensor.
In that case, the attachment method of a motion sensor is not specifically limited, For example, although a surface fastener, a snap, an adhesive, sewing, a magnet, a pocket etc. are illustrated, it is not limited to these. Of these, hook-and-loop fasteners are preferred.

In addition, various functions for imparting functions such as dyeing, raising, ultraviolet shielding or antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, negative ion generators, water repellents, and the like to the fabrics. Processing may be additionally applied.

  Examples of the motion sensor include an inertial sensor such as an acceleration sensor, a gyro sensor, and a geomagnetic sensor, an optical sensor, a mechanical sensor, a magnetic sensor, and an image sensor, but are not particularly limited. Of these, an inertial sensor is preferable.

  Further, the data obtained by the sensor may be analyzed and used for behavior analysis such as sports engineering, rehabilitation engineering, robot engineering, and worker management. In addition, such data may be used as a judgment criterion in the medical field when judgment is necessary in sports competitions, etc., or watching.

  Also, a composite product may be developed by combining data obtained by the sensor and other electronic terminals. Complex services include services that can make announcements in secondary media such as light and sound in response to data obtained from sensors, and other vital data (heart rate, blood pressure, breathing, body temperature, skin And services to be used by investigating the correlation with drying.

  Here, the IT service may be implemented using data obtained by the sensor. Examples of the IT service include a service for buying and selling the data and providing an application developed using the data. Further, the service may be used for a service for monitoring at a sports facility, a hospital, a nursing facility, a field work, or the like, and may be used for support that can provide the service from a remote place.

Since the garment of the present invention includes the fabric, the change in the adhesion between the sensor and the body is small even when the body is moved, and the motion sensor can be reliably adhered to the body and the three-dimensional posture information can be detected with high accuracy. In addition, the clothes are excellent in wearing comfort. In particular, when a crimped fiber having a torque of 30 T / m or less is included, the cloth surface is flat, and as a result, it is possible to detect three-dimensional posture information with higher accuracy and excellent wear comfort. It becomes.
Such clothing includes sports clothing, men's clothing, women's clothing, outerwear, innerwear, nightclothes, vests, stomachbands, hats, gloves, socks and the like.

EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited at all by these. In addition, each physical property in an Example is measured with the following method.
(1) Torque A sample (crimped yarn) of about 70 cm is stretched horizontally, an initial load of 0.18 mN × display tex (2 mg / de) is hung at the center, and both ends are aligned. The yarn begins to rotate due to the residual torque, but keeps the initial load until the initial load stops to obtain a twisted yarn. The twisted yarn having a length of 25 cm is measured with a tester under a load of 17.64 mN × display tex (0.2 g / de). The obtained twist number (T / 25 cm) is quadrupled to obtain the torque (T / m).

The skein is suspended from a hanging nail of the scale plate, an initial load of 6 g is applied to the lower part thereof, and a length L0 of the skein when a load of 300 g is further applied is measured. Immediately thereafter, the load is removed from the skein, the scale plate is removed from the hanging nail, and the skein is immersed in boiling water for 30 minutes to develop crimps. The skein after the boiling water treatment is taken out from the boiling water, the moisture contained in the skein is absorbed and removed by a filter paper, and air-dried at room temperature for 24 hours. This air-dried skein is hung on a hanging nail of the scale plate, a load of 300 g is applied to the lower part, and the length L1a of the skein is measured after 1 minute. The length L2a is measured. The crimp rate (CP) of the test filament yarn is calculated by the following formula.
CP (%) = ((L1a−L2a) / L0) × 100
(4) Stretchability and stretch recovery properties Two test pieces having a width of 5 cm and a length of 20 cm are collected from the fabric in either the horizontal direction or the vertical direction to obtain test pieces. Using a constant speed extension type tensile tester with a self-recording device, an initial load of 196.1 mN (20 gf) is applied to the test piece, and a constant load of 14.7 N (1.5 kgf) at a gripping interval of 10 cm and a tensile speed of 30 cm / min. Stretching up to 1%, calculate the stretch rate, that is, stretchability (%) by rounding off to one decimal place.

Subsequently, it is left for 1 minute and then returned to its original position at the same speed. After standing for 3 minutes, the residual elongation (up to 0.01 cm) is measured with a scale. From the drawn load-elongation curve, the elongation recovery rate, that is, the stretch recovery property (%) is calculated by rounding off one decimal place.
E (%) = ((L−L1) / L) × 100
Here, E: Elongation recovery rate, L = constant elongation (mm), and L1 = residual elongation (mm).

The above operation is repeated three times for the same test piece, and the operation is performed for each of the two test pieces under each condition. About stretch property and stretch recovery property, the average value of the measured value of a total of 6 points | pieces is calculated.
(5) Texture Based on the sensory evaluation of three testers, the texture is evaluated in four levels: “especially soft”, “soft”, “normal”, and “hard”.
(6) Ultraviolet shielding rate The ultraviolet shielding rate in the wavelength range of 280 to 400 nm is calculated with a spectrophotometer MPC-3100 manufactured by Shimadzu Corporation.
(7) Visible light shielding rate As a substitute characteristic of permeation resistance, a visible light shielding rate in a wavelength range of 400 to 700 nm is calculated with a spectrophotometer MPC-3100 manufactured by Shimadzu Corporation.
(8) Content of matting agent Calculated by the following formula.
Matting agent content (%) = Massing agent mass (gr) to be added / Polymer mass before adding matting agent (gr) × 100
(9) Accuracy of 3D posture information during exercise After wearing a garment equipped with an inertial sensor of Xsens motion capture system MVN-awinda as a motion sensor and performing calibration in a stationary state The operation of jumping on the spot and landing in the same posture is repeated 10 times, and the coordinate value (x axis, y axis, Z axis) of each sensor at the time of landing and the coordinate value (x of each sensor immediately after calibration) The average value of the difference between the axis, the y axis, and the Z axis was calculated. When the average value was within 5 cm, “accuracy was very good”, when the average value was within 10 cm, “accuracy was good”, and when the average value was 10 cm or more, “accuracy was bad”.
