JP7505953B2 - Wearable Best Clothing - Google Patents

Description

The present invention relates to a wearable vest, and more specifically to a vest equipped with a motion sensor, in which the position of the motion sensor is unlikely to shift even when the wearer moves.

Wearable clothing equipped with sensors such as motion sensors has been proposed in the past (for example, Patent Document 1).
However, in order to prevent the sensor from shifting, conventional sensors have a very tight structure relative to the size of the body, which makes them uncomfortable to wear, impairs the wearer's movements, and makes them difficult to put on and take off. On the other hand, if you try to improve the tight structure, the sensor will shift out of position during movement, which causes the sensor's detection function to not be fully utilized.

JP 2019-85671 A

The present invention has been made in consideration of the above background, and aims to provide a vest equipped with a motion sensor, in which the position of the motion sensor is unlikely to shift even when the wearer moves.

According to the present invention, there is provided "a wearable vest equipped with a motion sensor, comprising an outside air side fabric and a skin side fabric, with a sensor disposed between the outside air side fabric and the skin side fabric, the skin side fabric being made of power net, the skin side fabric having a pocket on the outside air side fabric side, with a motion sensor disposed in the pocket, the motion sensor disposed in the pocket being fixed within the pocket by a hook-and-loop fastener, the skin side fabric having a belt with a buckle, and comprising in the waist and sides of the vest a fabric containing ultrafine fibers with a single fiber diameter of 50 to 3000 nm ."

The present invention provides a vest equipped with a motion sensor, which is less likely to shift in position even when the wearer moves.

1 is a diagram showing an example of a vest of the present invention. In the front view of the vest, a buckled belt on a backrest is shown, but the buckled belt is usually not visible from the outside. In the back view of the vest, a backrest is shown, but the backrest is usually not visible from the outside. FIG. 2 is a diagram showing an example of a back panel (skin side fabric) having a pocket and a belt that constitutes the vest of the present invention.

The vest of the present invention will be described in detail below.
The vest wear of the present invention is a vest-type garment (sometimes called a "vest") that can be used as a wearable item, and has an outside air side fabric and a skin side fabric, and is provided with a motion sensor between the outside air side fabric and the skin side fabric. In this case, it is preferable that the outside air side fabric is a main body fabric, and the skin side fabric is a backrest.

Here, the fabric for the outside air side is preferably a fabric with a basis weight of 50 to 250 g/ ^m2 . If the basis weight is more than 250 g/ ^m2 , the weight of the vest may become heavy and the comfort of wearing may decrease. Conversely, if the basis weight is less than 50 g/ ^m2 , the strength of the fabric may decrease.

In addition, in the vertical or horizontal direction of the outdoor air side fabric, JIS L1096-2010
8.16.1 The elongation measured by method B is preferably 1% or more (more preferably 10 to 200%). If the elongation is less than 1%, flexibility may decrease.

The fibers constituting the exterior-side fabric are not particularly limited, and may be polyester fibers, polyurethane fibers, polyetherester fibers, acrylic fibers, nylon fibers, rayon fibers, acetate fibers, or natural fibers such as cotton, wool, or silk, or composites of these. Elastic fibers such as crimped fibers (such as polyester false-twist crimped yarn), elastic fibers (such as polyurethane fibers, polyetherester fibers), and composite fibers in which two components are bonded together in a side-by-side or eccentric core-sheath type (such as composite fibers of polytrimethylene terephthalate and polyethylene terephthalate) may also be used. In addition, these elastic fibers may be arranged in the core and other fibers in the sheath to form core-sheath composite yarns (air-mixed yarns, covering yarns, twisted yarns, composite spun yarns, etc.) that are included in the fabric.

The fibers constituting the exterior air side fabric may also contain one or more of the following: ultraviolet absorbers, micropore-forming agents (organic metal sulfonates), color inhibitors, heat stabilizers, flame retardants (antimony trioxide), fluorescent whitening agents, color pigments, antistatic agents (metal sulfonates), hydrophilizing agents, moisture absorbents (polyoxyalkylene glycol), antibacterial agents, and other inorganic particles.

The structure of the fabric on the outside air side is not particularly limited, and may be any of knitted fabrics, woven fabrics, and nonwoven fabrics. Suitable examples include woven fabrics with weave structures such as plain weave, twill weave, and satin, knitted fabrics with knit structures such as jersey, smooth, milling, piqué, cross-knit, denby, and half, and nonwoven fabrics, but are not limited to these. The number of layers may be a single layer, or two or more layers. Among these, knitted fabrics are preferred in terms of obtaining excellent flexibility. Knitted fabrics with warp knitting or weft knitting (circular knitting) structures are particularly preferred.

On the other hand, power net is preferred as the skin side fabric in order to improve the shape retention of the vest. In particular, power net made of nylon fibers and polyurethane fibers with a total fineness of 300 to 800 dtex and 5 to 40 filaments is preferred. Power net with a warp knit structure is also preferred.

It is preferable that such skin-side fabric has a pocket on the surface of the fabric facing the outside air, and that the pocket is equipped with a motion sensor (sometimes called a "sensor"). In this case, examples of the motion sensor include, but are not limited to, inertial sensors such as acceleration sensors, gyro sensors, and geomagnetic sensors, optical sensors, mechanical sensors, magnetic sensors, and image sensors. Among these, inertial sensors are preferable. For example, a sensor that can detect acceleration in three axial directions, angular velocity around three axes, and orientation in three axial directions, as described in JP 2019-88469 A, is preferable.

It is also preferable that the sensor disposed in the pocket is fixed in the pocket by a hook-and-loop fastener. Here, as the hook-and-loop fastener, for example, a hook-and-loop fastener composed of fabric a containing filament yarn A with a single fiber diameter of 1000 nm or less (preferably 100 to 800 nm) and raised fabric b as described in JP 2009-285144 A is used, and it is preferable that one of fabric a and raised fabric b is attached to the inside of the pocket and the other is attached to the sensor. Not only does this prevent the sensor from shifting, but it also requires no force to attach and detach, making the attachment and detachment operation very easy, which is preferable. It is also preferable if the skin side fabric has a belt with a buckle, as this makes it even less likely that the sensor will shift from the attached position.

The vest of the present invention may be equipped with a single sensor, but may also be equipped with multiple sensors (preferably 2 to 5). In this case, the sensors may be placed on the back and abdomen.

In the vest of the present invention, in order to improve the adhesion between the vest and the body, a fabric containing ultrafine fibers having a stretchability in at least one of the horizontal and vertical directions within a range of 10 to 250% and a single fiber diameter of 50 to 3000 nm (preferably 100 to 800 nm), as described in JP 2019-85671 A, may be used as the anti-slip fabric. For example, such an anti-slip fabric may be used in the waist and sides. In addition, in the vest of the present invention, a belt may be attached to the outside air side fabric (main fabric).

The vest of the present invention has the above-mentioned configuration, and is equipped with a motion sensor, and the vest is provided in which the attachment position of the motion sensor is unlikely to shift even when the wearer moves. The vest is suitable for use as a wearable vest in sports such as golf and tennis, and in choreography such as dancing.

The present invention will be explained in more detail below with reference to examples, but is not limited to these.

[Example 1]
First, a vest body fabric was obtained using a composite yarn in which a polyurethane fiber was covered with a polyester fiber containing an ultraviolet absorbing agent. The vest body fabric had a front opening and a zipper.

On the other hand, a backrest (skin side fabric) made of nylon power net was obtained as shown in Figure 2. A pocket was attached to the fabric side facing the outside air of the backrest, and a motion sensor was placed in the pocket. The sensor was fixed inside the pocket with a hook-and-loop fastener (Fasteno (registered trademark) manufactured by Teijin Frontier Co., Ltd.).

Next, the backrest was attached to the main fabric to obtain a vest, which was then used as a golf vest wear.
The vest is a wearable vest equipped with a motion sensor, and the position of the motion sensor is unlikely to shift even when the wearer moves.

[Example 2]
According to the description of JP 2019-85671 A, the following anti-slip fabric was obtained.
(Method of manufacturing anti-slip fabric)
A honeycomb bare knit fabric was knitted on a 28G double circular knitting machine using polyester false twist crimp textured yarn 33 dtex/36 fil, polyurethane elastic yarn 44 dtex/1 fil, and the following islands-in-the-sea type composite fiber 56 dtex/10 fil.

The islands-in-sea composite fiber was produced as follows. Using polyethylene terephthalate (melt viscosity at 280°C: 1200 poise) as the island component and polyethylene terephthalate (melt viscosity at 280°C: 1750 poise) copolymerized with 6 mol% 5-sodium sulfoisophthalic acid and 6 wt% polyethylene glycol with a number average molecular weight of 4000 as the sea component (melt viscosity at 280°C: 1750 poise) (dissolution rate ratio (sea/island) = 230), an islands-in-sea composite undrawn fiber with a sea:island ratio of 30:70 and number of islands = 836 was melt spun at a spinning temperature of 280°C and a spinning speed of 1500 m/min and wound up once. The resulting undrawn yarn was roller-drawn at a drawing temperature of 80°C and a draw ratio of 2.5 times, then heat-set at 150°C and wound up. The resulting islands-in-the-sea composite drawn yarn had a fineness of 56 dtex/10 fil, and when the fiber cross section was observed using a transmission electron microscope (TEM), the islands were found to be round and had a diameter of 700 nm.

The knitted fabric was then subjected to the usual dyeing and weight reduction process to turn the islands-in-the-sea composite fibers into ultrafine fibers with a single fiber diameter of 700 nm. The weight reduction process involved 30% alkaline weight reduction at 70°C using a 2.5% NaOH aqueous solution. The fabric was then subjected to a water absorption process in the final set step. For the water absorption process, a hydrophilizing agent (polyethylene terephthalate-polyethylene glycol copolymer) was applied to the knitted fabric in an amount of 0.30% by weight relative to the weight of the knitted fabric.

The knitted fabric thus obtained had a basis weight of 177 g/ ^m2 , density of 82 courses/2.54 cm, 52 wales/2.54 cm, elasticity: vertical 52.9%, horizontal 42.5%, elongation recovery: vertical 91.7%, horizontal 92.7%, friction coefficient: 2.18. Next, in the vest wear obtained in Example 1, the anti-slip fabric was sewn so as to go around the waist and to cover a part of the power net in the sides, with the high friction resistance surface of the anti-slip fabric facing the skin. A belt was also attached to the waist to obtain the vest shown in Figure 1, which was used as a golf vest wear.
This vest wear is one in which the sensor attachment position is unlikely to shift due to the wearer's movements, and the measurements taken by the sensor are very stable.

[Comparative Example 1]
Except for the fact that no skin-facing fabric was used and that a pocket was attached to the main fabric and a motion sensor was placed inside, this vest was the same as in Example 1. This vest was easy to put on and take off and was as comfortable to wear as Example 1, but the sensor attachment position was easily displaced by the wearer's movements and the sensor measurement was insufficient.

The present invention provides a vest equipped with a motion sensor, in which the position of the motion sensor does not easily shift even when the wearer moves, and has great industrial value.
