Description

Technical Field

[0001] The present invention relates to a wearable heat storage component and a pair of pants containing the heat storage component. Background Technology

[0002] Keeping areas of the body warm, such as the back, abdomen, knees, and neck, is crucial for health. For example, a cold abdomen can affect the spleen and stomach, while cold air can cause pain in the knees. Women are particularly prone to feeling cold in their lower abdomen and waist during menstruation. Therefore, various types of clothing specifically designed to keep these areas warm have emerged on the market.

[0003] Japanese Patent Application Publication No. 2002-658A discloses a type of menstrual underwear in which at least a portion of the inner side of the underwear body, in contact with the lower abdomen and / or waist, has a lower thermal conductivity than the underwear body itself. This is intended to improve insulation and alleviate coldness in the lower abdomen and waist. However, while a low thermal conductivity can reduce heat loss, the effect is not significant.

[0004] Chinese patent CN203492802U discloses a multifunctional waist-cinching underwear. The underwear body extends upwards from the waist to form a waistband, and the abdomen of the underwear body has a pocket for holding a heating pad to relieve menstrual pain. While the heating effect of the heating pad does relieve pain, the pocket increases the processing steps of the underwear, the installation and removal of the heating pad is inconvenient, and it also increases the weight of the underwear, affecting wearing comfort. Summary of the Invention

[0005] The purpose of this invention is to provide a wearable heat storage component that is simple to manufacture, has good warmth retention, and can be used anywhere without restriction, as well as trousers equipped with the heat storage component.

[0006] The technical solution of this invention:

[0007] (1) The wearable heat storage component of the present invention includes a heat storage body and a tightening device for bringing the heat storage body into close contact with the human body. The heat storage body includes at least one layer of heat storage fabric, and the overall air content of the heat storage fabric is 4 cm³. 3 / 100cm 2 The above indicates that the air content reduction of a single-layer heat-storing fabric at 1.0 kPa is 1.6 cm. 3 / 100cm 2 the following.

[0008] (2) After the wearable heat storage component of (1) above forms a pressure-free and seamless enclosure on the human body, the pressure of the heat storage body on the human body increases by 0.2 to 0.4 kPa for every 2 cm that the tightening device shrinks.

[0009] (3) The wearable heat storage component of (1) above contains one or more of the following yarns in the heat storage fabric: moisture-absorbing and heat-generating fibers, bulky yarn, or light-absorbing and heat-generating yarn.

[0010] (4) The wearable heat storage component of (1) or (2) above, the heat storage fabric is one of the following structures: brushed fabric, napped fabric or fish scale fabric.

[0011] (5) The wearable heat storage component described in (1) or (2) above has a heat storage fabric area of ​​80–200 cm². 2 .

[0012] (6) The wearable heat storage component of (1) or (2) above, wherein the air permeability of the heat storage fabric is 75cm. 3 / cm 2 / s or less.

[0013] (7) The wearable heat storage component of (2) above, wherein the pressure difference between any two points of the heat storage body is less than 0.2 kPa.

[0015] (9) The heat storage body of the pants described in (8) is fixedly connected to the pants fabric by quilting, hot pressing, glue strips or adhesives.

[0016] This invention utilizes a heat-retaining fabric with high initial air content and minimal change in air content under pressure to obtain a heat-retaining component with good warmth retention. The heat-retaining component can be used alone on body parts requiring warmth or pressure, and when applied to the lower abdomen, it can also be directly fixed inside trousers.

[0024] This invention provides a wearable heat storage component that can be applied to any part of the human body. The heat storage component includes a heat storage body and a tightening device to ensure the heat storage body fits snugly against the human body. Specifically, it can be as follows: Figure 1 As shown, the tightening device is a single unit. At both ends along its length, it features adjustable fastening methods such as Velcro, multi-row fasteners, and zippers. A heat-retaining fabric, serving as the heat-retaining body, is attached to the middle of the device, with the fabric positioned on the body side during use. Alternatively, it can be... Figure 2 As shown, two straps are directly connected to opposite sides of the heat-storing fabric, which serves as the heat-storing body. The ends of the straps are secured with Velcro, multi-row fasteners, zippers, or other methods to adjust the tightening length; or as... Figure 3 As shown, the heat-storing fabric is first laid flat in a storage bag to form a heat-storing body. Then, two straps are connected to opposite sides of the heat-storing body. At both ends of the straps, Velcro, multi-row connecting buckles, zippers, and other fixing methods that can adjust the tightening length are provided.

[0025] For the above Figure 3 The materials used for the storage bags described herein are not specifically limited. From the perspective of being lightweight, comfortable, and not protruding after use, the materials can be ordinary lightweight fabrics used for close-fitting clothing, such as cotton, polyester, spandex, etc.

[0026] The function of the heat storage body is to increase the air content of the application area, reduce air circulation, and reduce heat loss while accumulating heat, thereby achieving a localized warming effect and relieving pain in painful areas. To achieve this effect, the heat storage body of the present invention includes at least one layer of heat storage fabric, and the overall air content of the heat storage fabric is 4cm³. 3 / 100cm 2 The above applies. If the air content of the overall heat-retaining fabric is less than 4 cm³... 3 / 100cm 2 If the air content of the heat-storing fabric is too high, the effect of using the heat-storing component will be unsatisfactory, and the localized warmth retention effect cannot be achieved. Although the higher the air content of the heat-storing fabric, the better the warmth retention effect of the heat-storing body, if the total air content of the heat-storing fabric in the heat-storing body is too high, the body parts using the heat-storing component will feel stuffy, sweat easily, and the comfort will be reduced. Considering both warmth retention and human comfort, the present invention preferably uses an air content of 7-21 cm³ for the overall heat-storing fabric in the heat-storing body. 3 / 100cm 2 .

[0027] In practical applications, either a single layer of heat-retaining fabric or multiple layers can be used. However, considering human comfort, when using multiple layers of heat-retaining fabric, it is preferable that their total air content be around 21cm³. 3 / 100cm 2 the following.

[0028] In addition to the heat-storing body, the heat-storing component of this invention also includes a tightening device that keeps the heat-storing body in close contact with the human body. The tightening device serves two main purposes: first, it ensures the heat-storing component stays wrapped around the corresponding part of the body without falling off; second, it applies pressure to the area where the heat-storing component is applied. This pressure effect is primarily directed at areas of pain. Pain is transmitted through nerves, which include tactile fibers and pain fibers. Applying pressure to the painful area increases the sensitivity of the tactile fibers and reduces the input of the pain fibers, thus alleviating the pain. Within the range acceptable to the human body, the greater the tightening of the tightening device, the greater the pressure on the painful area, and the more effectively the pain is relieved. However, when the tightening reaches a certain value, the air content of the heat-storing fabric in the heat-storing body will decrease significantly due to external pressure, reducing or eliminating the heat-insulating effect.

[0029] To maintain the heat-storing effect of the heat-storing body under pressure, the single-layer heat-storing fabric of this invention exhibits a gas content reduction of 1.6 cm³ under 1.0 kPa pressure. 3 / 100cm 2 The following can maintain the static air layer content between the heat storage fabrics after being compressed.

[0030] It should be noted that the reason for choosing the change in air content of the fabric under a pressure of 1.0 kPa as the test for whether the heat-storing fabric can maintain its heat-keeping effect is that the inventors of this invention have found that this pressure is a better value in which the human body does not feel a tightness and can clearly feel a reduction in pain.

[0031] Given that individual perception varies, when designing the heat storage component, by selecting a suitable heat storage body fabric, it is preferable to form a pressure-free and seamless enclosure on the human body. For every 2cm contraction of the tightening device, the pressure exerted by the heat storage body on the human body increases by 0.2–0.4 kPa. Adjusting the tightness of the tightening device allows for better control of pressure changes on the human body, preventing insufficient pain relief due to small pressure changes and excessive tightness or discomfort.

[0032] Meanwhile, through the reasonable setting of the tightening device, the overall force on the heat storage body can be uniform when tightening, and the pressure difference between any two points is small, below 0.2 kPa, so that the heat storage body will not detach from the human body and cause a decrease in heat retention.

[0033] By adjusting the tightening device, the pressure can be adjusted within the range of 0.2 to 1.0 kPa, allowing different people to experience the effects of warmth and pain relief when using it.

[0034] To meet the requirement of gas content between 4 and 21 cm³ 3 / 100cm 2 To further improve the heat retention effect of the heat-storing fabric, the heat-storing fabric preferably contains one or more of the following: moisture-absorbing and heat-generating fibers, bulky yarn, conductive yarn, and light-absorbing and heat-generating yarn. The moisture-absorbing and heat-generating fibers mainly refer to fibers with high standard moisture regain, such as viscose fiber, acrylic fiber, and modal fiber; the conductive fibers mainly refer to carbon fiber and graphene fiber, which can generate heat by adding an external power source (such as a power bank or button battery); the light-absorbing and heat-generating fibers mainly refer to fabrics with added graphene particles, rare metal particles, etc., that have the function of absorbing light and generating heat.

[0035] The present invention does not specifically limit the specific composition of the aforementioned preferred fibers, which may include cellulose fibers, polyester fibers, cotton fibers, nylon fibers, etc. In order to effectively improve the heat preservation effect of the heat storage fabric after adding functional yarns such as moisture-absorbing and heat-generating fibers, bulky yarns, conductive yarns, or light-absorbing and heat-generating yarns, the content of the aforementioned functional yarns in the heat storage fabric is preferably above 20 wt%.

[0036] The air content of the heat-retaining fabric is mainly achieved through the fabric's weave, such as brushed, napped, fish-scale, cotton-wool, terry, plain, and rib knit. Among these weaves, brushed, napped, and fish-scale weaves have a napping effect, allowing more still air layers to form between the heat-retaining fabric and the human body during use, resulting in better warmth retention and thus becoming preferred.

[0037] Since heat is lost through air circulation, reducing the ventilation of the heat-storing fabric can, to some extent, maintain the heat-storing body's insulation effect. Preferably, the ventilation of the heat-storing fabric is 75 cm². 3 / cm 2 / s or less.

[0038] This invention does not impose particular limitations on the size and shape of the heat-storing body, as long as it can cover the area requiring a warming effect. If the area of ​​the heat-storing body is too small, the warming effect tends to decrease; if the area of ​​the heat-storing body is too large, it will cause a stuffy feeling and reduce comfort. Therefore, the area of ​​the heat-storing fabric is preferably 80–200 cm². 2Of course, different sizes and shapes can be selected depending on the affected area. For example, when the affected area is the knee or elbow joint, the heat storage body is preferably circular or elliptical in shape, and its size is preferably 50–150 cm. 2 When the target area is the abdomen, the heat storage body is preferably elliptical or rectangular in shape, and its size is preferably 80–200 cm. 2 When the target area is the waist, the heat storage body is preferably elliptical or rectangular in shape, and its size is preferably 100-200 cm. 2 When the target area is the lower leg, the heat storage body is preferably elliptical or rectangular in shape, and its size is preferably 80–200 cm. 2 .

[0039] When used for keeping the abdomen warm and relieving pain during menstruation, the heat-retaining unit is generally placed at the Qihai acupoint, which is 5cm below the navel. In this case, the heat-retaining unit can be used alone, or it can be fixed to the pants, with the heat-retaining unit located on the inside of the front panel of the pants. The tightening device can be directly fixed to the heat-retaining unit, or... Figure 4 The design is shown at the side seam of the trousers, horizontally positioned at the abdominal area. The trousers can be long pants, shorts, underwear, etc.

[0040] The heat storage body is preferably fixedly connected to the trouser fabric by quilting, hot pressing, adhesive strips or adhesives.

[0041] This invention uses heat-retaining fabric directly as a thermal insulation material, which can be used on various parts of the human body, is lightweight, durable, and has good thermal insulation properties. It can also maintain a good thermal insulation effect after being subjected to a certain amount of pressure.

[0042] The present invention will be further described below with reference to embodiments and comparative examples.

[0043] The testing methods for each parameter involved in this invention are as follows:

[0044] (1) Gas content

[0045] ① When the heat-retaining fabric can be removed from the heat-retaining body or trousers without damaging it, a 3×3cm sample of the fabric should be cut. Referring to the compression rate and compression elasticity tests in standard JIS L 1096:2010, the cut fabric should be tested using a compression elasticity testing machine under a pressure of 7gf / cm². 2 At that time, the fabric thickness d1 (cm) was adjusted to a pressure of 800 gf / cm. 2 The fabric thickness at this time was d2 (cm), and the fabric thickness values ​​read by the compression elasticity testing machine were accurate to three decimal places. The air content of the fabric was (d1-d2)×100 (cm). 3 / 100cm 2 Three samples were taken for testing, and the final result was the average value. When there is only one layer of heat storage fabric in the heat storage body, the single layer of heat storage fabric can be tested directly; when there are multiple layers of heat storage fabric in the heat storage body, they are tested as a whole.

[0046] ② When the heat-storing fabric cannot be removed from the heat-storing component or pants without damage, calculate the air content of the part containing the heat-storing fabric and the part without the heat-storing fabric according to the test method (1)①. The difference between the two is the air content of the heat-storing fabric. Take 3 pieces of heat-storing fabric for testing, and take the average value of the final result.

[0047] (2) The reduction in air content of the heat storage fabric at a pressure of 1.0 kPa

[0048] ① When the heat-storing fabric can be removed from the heat-storing body or pants without damaging it, test the fabric thickness d1 (cm) according to the process of test method (1)①. Based on 1.0 kPa = 1000 N / m 2 =102kg / m 2 =20.4g / 2cm 2 =10.2g / cm 2 Adjust the equipment pressure to 10.2 gf / cm 2 The fabric thickness d3 (cm) was measured at this time. The reduction in air content of the heat-storing fabric under a pressure of 1.0 kPa is (d1-d3)×100 (cm). 3 / 100cm 2 Three samples were tested separately, and the final result was the average value. When there is only one layer of heat storage fabric in the heat storage body, the result is the reduction value of air content of the single layer of heat storage fabric; when there are multiple layers of heat storage fabric in the heat storage body, it is tested as a whole, and the result is divided by the number of layers of heat storage fabric to obtain the reduction value of air content of the single layer of heat storage fabric.

[0049] ② When the heat-storing fabric cannot be removed from the heat-storing component or pants without damage, test the reduction in air content of the part containing the heat-storing fabric and the part without the heat-storing fabric at a pressure of 1.0 kPa according to the test method (2)①. The difference between the two is the reduction in air content of the heat-storing fabric at a pressure of 1.0 kPa. Take 3 pieces of heat-storing fabric for testing, and take the average value of the final result. When there is only one layer of heat-storing fabric in the heat-storing body, the result is the reduction in air content of the single layer of heat-storing fabric; when there are multiple layers of heat-storing fabric in the heat-storing body, divide the result by the number of layers of heat-storing fabric to obtain the reduction in air content of the single layer of heat-storing fabric.

[0050] (3) The increase in pressure on the human body from the heat storage body when the tightening device contracts by 2cm

[0051] After the heat-retaining fabric forms a pressure-free, seamless enclosure on the human body, the pressure is tested using a clothing pressure device (PRESSURECONVERTER, model AMI3037-5S). The testing method is as follows: First, turn on the device and preheat for 30 minutes; then, zero the device by calibrating the required channel reading on the machine body and adjusting it to 0 using the machine's dedicated screwdriver; next, prepare a small airbag; then, select the Qihai acupoint on the abdomen, which is 5cm below the navel, and fix the small airbag at this point, testing the initial pressure P1. Tighten the heat-retaining fabric by 2cm and fix it, recording the pressure P2 at this point. The pressure increment P = P2 - P1. Repeat the test twice and take the average value.

[0052] (4) Ventilation

[0053] The breathability test was conducted according to the A method in the reference standard JIS L1096:2010. The principle of the test is to measure the amount of air passing through the gaps in the fabric structure and evaluate the difficulty of air circulation. It indirectly reflects the warmth retention of the fabric. If the breathability is too small, it will cause stuffiness due to poor breathability; if the breathability is too large, the warmth retention will decrease. (5) Evaluation of warmth retention effect, pain suppression effect and stuffiness

[0054] Ten people with pain in the same area were selected. They were asked to wear heat-retaining parts or pants and evaluate their warmth retention, pain suppression, and stuffiness. The rating scale ranged from 1 to 5. The final result was the average score of the ten people. An average score of 3 or above was considered satisfactory.

[0055] In the evaluation of warmth retention, 1 point is given for no warmth retention, 3 points for good warmth retention, 5 points for excellent warmth retention, 2 points for warmth retention between 1 and 3 points, and 4 points for warmth retention between 3 and 5 points.

[0056] In the evaluation of pain suppression effect, no pain suppression effect is rated as 1 point, good pain suppression effect is rated as 3 points, excellent pain suppression effect is rated as 5 points, pain suppression effect between 1 and 3 points is rated as 2 points, and pain suppression effect between 3 and 5 points is rated as 4 points.

[0057] In the evaluation of stuffiness, feeling extremely stuffy is rated as 1 point, and feeling no stuffiness is rated as 5 points. In between, the stuffiness is rated as 2 points, 3 points, and 4 points from strong to weak.

[0058] The present invention will be further described in detail below based on specific embodiments.

[0059] Example 1

[0060] The fabric was woven from 80-count acrylic / viscose blended yarn, 84T-72F cationic dyeable polyester, and 20D spandex, with a fish-scale weave. Its air content was measured to be 17 cm³. 3 / 100cm 2 The fabric's air content reduction at 1.0 kPa was measured using a compression elasticity testing machine and found to be 0.54 cm³. 3 / 100cm 2 Ventilation volume is 40cm 3 / cm 2 / s. Cut out an 8×10cm piece with an area of ​​80cm². 2 Rectangular fabrics are used as heat-retaining fabrics, such as Figure 2 As shown, fastening devices of the Velcro type are fixed to both ends of the heat-retaining fabric to form a wearable heat-retaining component. The wearable heat-retaining component was tested, and the specific evaluation results are shown in Table 1.

[0061] Examples 2-3

[0062] The air content of the fabric was changed by altering its thickness, and the rest was the same as in Example 1. The evaluation results are shown in Table 1.

[0063] Example 4

[0064] The air permeability of the fabric was changed by altering its density, and the rest was the same as in Example 1. The evaluation results are shown in Table 1.

[0065] Examples 5-7

[0066] Maintaining an aspect ratio of 5:4, the area of ​​the heat-retaining fabric was changed, and the rest was the same as in Example 1. The evaluation results are shown in Table 1.

[0067] Example 8

[0068] Change the tightening device to a zipper type, such as Figure 2 As shown, the rest is the same as in Example 1, and the evaluation results are shown in Table 1.

[0069] Example 9

[0070] Change the type of tightening device to a drawstring type, such as Figure 4 As shown, the rest is the same as in Example 1, and the evaluation results are shown in Table 1.

[0071] Examples 10-11

[0072] The fabric structure was changed, but the rest was the same as in Example 1. The evaluation results are shown in Table 2.

[0073] Example 12

[0074] The polyester was replaced with graphene polyester yarn, a yarn with light-absorbing and heat-generating effects, while the rest remained the same as in Example 1. The evaluation results are shown in Table 2.

[0075] Example 13

[0076] The ordinary acrylic fiber was replaced with bulky acrylic yarn, and the rest was the same as in Example 1. The evaluation results are shown in Table 2.

[0077] Example 14

[0078] like Figure 5 As shown, the heat-retaining fabric was sewn onto the inside of the front panel of the underwear by stitching, and the tightening device (Velcro) was fixed to the side seams on both sides of the underwear. The rest was the same as in Example 1. The evaluation results are shown in Table 2.

[0079] Comparative Example 1

[0080] Adjust the air content of the fabric to 2cm by changing the fabric thickness. 3 / 100cm 2 The rest is the same as in Example 1, and the evaluation results are shown in Table 2.

[0081] Because the fabric has too low air content, when used as a heat-storing fabric in heat-storing components, it results in poor heat retention and no pain-suppressing effect.

[0082] Comparative Example 2

[0083] Adjust the fabric's air content to 25cm by changing its thickness. 3 / 100cm 2 The rest is the same as in Example 1, and the evaluation results are shown in Table 2.

[0084] Because the fabric has a high air content, when used as a heat-retaining fabric in heat-retaining components, it causes a noticeable stuffy feeling on the human body.

[0085] Comparative Example 3

[0086] The yarn composition was changed to 37% viscose, 27% acrylic, 27% cotton, and 9% spandex, and the weave was changed to plain weave. The air content reduction of the heat-retaining fabric under 1.0 kPa pressure was 1.8 cm. 3 / 100cm 2 The rest is the same as in Example 1, and the evaluation results are shown in Table 2.

[0087] Because the fabric loses a significant amount of air content after being stressed, the heat-retaining components have poor warmth retention after being tightened, and there is no pain-suppressing effect.

[0088]
