以下將以圖式揭露本發明的複數個實施方式，為明 確地說明起見，許多實務上的細節將在以下敘述中一併說明。然而，應瞭解到，這些實務上的細節不應用以限制本發明。也就是說，在本發明部分實施方式中，這些實務上的細節是非必要的。此外，為簡化圖式起見，一些習知慣用的結構與元件在圖式中將以簡單示意的方式繪示之。 A plurality of embodiments of the present invention will be disclosed in the following drawings for clarity. For the sake of clarity, many practical details will be explained in the following description. However, it will be understood that these practical details should not limit the invention. That is to say, in some embodiments of the present invention, these practical details are not necessary.

本揭露內容提供一種電熱織物，其可提供均勻分布的熱，並可透過孔洞結構及彎折部的配置來提升熱分布的均勻性。 The present disclosure provides an electric heating fabric that can provide evenly distributed heat, and can improve the uniformity of heat distribution through the configuration of the hole structure and the bending portion.
第1圖繪示根據本揭露一實施方式的電熱織物100的正視示意圖。電熱織物100包括本體區110以及多個發熱區130(例如，兩個以上的發熱區130)，且各發熱區130連接於本體區110的一側並具有孔洞結構H。相鄰的發熱區130間具有間隔D，且間隔D在發熱區130連接於本體區110處具有彎折部150。當對電熱織物100通電時，其可藉由電熱效應來產生熱，而電阻較高的區域可產生較多的熱(亦即可達到較高的溫度)。由於在本揭露的電熱織物100中，發熱區130的平均電阻高於本體區110的平均電阻，因此發熱區130的溫度會高於本體區110的溫度，從而適用於保暖。在一些實施方式中，電熱織物100可具有0.01Ω/□至1Ω/□的表面電阻，使其達到良好的保暖效果。
Figure 1 illustrates a schematic front view of an electrothermal fabric 100 according to an embodiment of the present disclosure. The electric heating fabric 100 includes a body area 110 and a plurality of heating areas 130 (for example, more than two heating areas 130), and each heating area 130 is connected to one side of the body area 110 and has a hole structure H. There is a gap D between adjacent heating areas 130 , and the gap D has a
在一些實施方式中，電熱織物100可包括聚酯布料以及導電金屬。在一些實施方式中，導電金屬可配置於聚酯布料的表面，以於聚酯布料的表面形成金屬薄膜。在 一些實施方式中，可透過含浸或網版印刷的方式將例如是銅、銀或鎳等金屬或合金配置在聚酯布料上，從而製作成電熱織物100。在一些實施方式中，電熱織物100的厚度可介於30μm至70μm間，且其中金屬薄膜的厚度可介於3μm至10μm間，從而提供輕量化及穿戴舒適性。 In some embodiments, the electrothermal fabric 100 may include polyester fabric and conductive metal. In some embodiments, conductive metal can be disposed on the surface of the polyester cloth to form a metal film on the surface of the polyester cloth. exist In some embodiments, metals or alloys such as copper, silver, or nickel can be disposed on polyester fabric by impregnation or screen printing to produce the electrothermal fabric 100 . In some embodiments, the thickness of the electrothermal fabric 100 may range from 30 μm to 70 μm, and the thickness of the metal film may range from 3 μm to 10 μm, thereby providing lightweight and wearing comfort.
各發熱區130連接於本體區110的一側，且相鄰的發熱區130間具有間隔D。在一些實施方式中，間隔D可以固定的寬度配置於相鄰的發熱區130間。間隔D在發熱區130連接於本體區110處具有彎折部150，當熱由發熱區130往本體區110移動時，彎折部150可避免熱累積在發熱區130與本體區110的連接處，從而使得電熱織物100可提供均勻分布的熱。在一些實施方式中，可透過雷射雕刻或化學蝕刻的方式形成彎折部150。
Each heating area 130 is connected to one side of the body area 110, and there is a distance D between adjacent heating areas 130. In some embodiments, the gap D can be configured with a fixed width between adjacent heating areas 130 . The gap D has a
各發熱區130具有孔洞結構H。在一些實施方式中，孔洞結構H可以等間距交錯或陣列地排列於發熱區130中。在一些實施方式中，孔洞結構H可佔發熱區130的整體表面積的15%至85%，以使發熱區130達到一定的平均電阻，並使發熱區130具有足夠硬挺的結構。詳細而言，當孔洞結構H佔發熱區130的整體表面積的15%以下時，可能導致發熱區130的平均電阻太低；而當孔洞結構H佔發熱區130的整體表面積的85%以上時，則可能導致發熱區130的硬挺性不足，不利於電熱織物100後續應用的配置與固定。在一些實施方式中，可透過雷射雕刻或化學蝕刻的方式形成孔洞結構H。 Each heating area 130 has a hole structure H. In some embodiments, the hole structures H may be arranged in the heating area 130 in a staggered or array manner at equal intervals. In some embodiments, the hole structure H may account for 15% to 85% of the entire surface area of the heating area 130 so that the heating area 130 reaches a certain average resistance and has a sufficiently stiff structure. Specifically, when the hole structure H accounts for less than 15% of the entire surface area of the heating area 130, the average resistance of the heating area 130 may be too low; and when the hole structure H accounts for more than 85% of the entire surface area of the heating area 130, the average resistance of the heating area 130 may be too low. This may result in insufficient stiffness of the heating area 130, which is not conducive to the configuration and fixation of the electrothermal fabric 100 for subsequent applications. In some embodiments, the hole structure H can be formed by laser engraving or chemical etching.
在一些實施方式中，發熱區130及本體區110皆可具有孔洞結構H，且發熱區130的孔洞密度(分布密度)大於本體區110的孔洞密度，以使發熱區130的平均電阻高於本體區110的平均電阻。在一些實施方式中，發熱區130中相鄰的孔洞結構H的中心點間的距離可介於2mm至12mm間，以使得孔洞結構H可以合適的密度分布於發熱區130中。在另一些實施方式中，本體區110可不具有孔洞結構H，從而提高發熱區130與本體區110兩者間的平均電阻的差值。 In some embodiments, both the heating area 130 and the body area 110 may have a hole structure H, and the hole density (distribution density) of the heating area 130 is greater than the hole density of the body area 110, so that the average resistance of the heating area 130 is higher than that of the body. Average resistance of zone 110. In some embodiments, the distance between the center points of adjacent hole structures H in the heating area 130 can be between 2 mm and 12 mm, so that the hole structures H can be distributed in the heating area 130 with a suitable density. In other embodiments, the body region 110 may not have the hole structure H, thereby increasing the difference in average resistance between the heating region 130 and the body region 110 .
在一些實施方式中，發熱區130可具有緩衝區域132，且緩衝區域132可位於發熱區130中相鄰於本體區110的位置。更詳細而言，彎折部150可位於緩衝區域132中，並受緩衝區域132夾置。在一些實施方式中，緩衝區域132的孔洞密度可小於發熱區130的其他部分的孔洞密度，使得緩衝區域132的平均電阻可低於發熱區130的其他部分的平均電阻。如此一來，緩衝區域132可避免熱累積在發熱區130與本體區110的連接處。在一些實施方式中，緩衝區域132的寬度可由本體區110朝向發熱區130的方向漸縮，使得熱可更均勻地分布於電熱織物100中。
In some embodiments, the heating area 130 may have a
在一些實施方式中，電熱織物100更可包括分別連接各發熱區130的多個延伸區170，其可提升電熱織物100的結構強度，有利於電熱織物100後續應用的配置與固定。在一些實施方式中，相鄰的延伸區170間可具有間隔D'，且間隔D'可以固定的寬度配置於相鄰的延伸區170 間。在一些實施方式中，各延伸區170間的間隔D'與各發熱區130間的間隔D可彼此連通。在一些實施方式中，延伸區170亦可具有孔洞結構H，且延伸區170的孔洞密度小於發熱區130的孔洞密度，使得延伸區170可具有良好的結構強度。在另一些實施方式中，延伸區170可不具有孔洞結構H，以進一步提升延伸區170的結構強度。 In some embodiments, the electric heating fabric 100 may further include a plurality of extension areas 170 respectively connected to each heating area 130, which can improve the structural strength of the electric heating fabric 100 and facilitate the configuration and fixation of the electric heating fabric 100 for subsequent applications. In some embodiments, there may be a gap D' between adjacent extension regions 170, and the gap D' may be configured with a fixed width at the adjacent extension regions 170. between. In some embodiments, the spacing D' between the extension regions 170 and the spacing D between the heating regions 130 may be connected to each other. In some embodiments, the extension area 170 may also have a hole structure H, and the hole density of the extension area 170 is smaller than the hole density of the heating area 130 , so that the extension area 170 may have good structural strength. In other embodiments, the extension area 170 may not have the hole structure H to further enhance the structural strength of the extension area 170 .
在一些實施方式中，電熱織物100的相對兩表面可配置披覆膠皮，且披覆膠皮可透過膠膜貼附於電熱織物100的表面。披覆膠皮配置以保護電熱織物100，以避免電熱織物100直接暴露於外界環境中，從而延長電熱織物100的使用壽命並提高電熱織物100的水洗牢度。在一些實施方式中，披覆膠皮可例如是聚醯亞胺的絕緣耐高溫材料，且膠膜可例如是聚對苯二甲酸乙二酯或聚氨酯等絕緣耐高溫材料。在一些實施方式中，膠膜可經熱壓滲透以將披覆膠皮固定於電熱織物100。 In some embodiments, two opposite surfaces of the electric heating fabric 100 can be covered with rubber, and the covering rubber can be attached to the surface of the electric heating fabric 100 through the rubber film. The rubber covering is configured to protect the electric heating fabric 100 to prevent the electric heating fabric 100 from being directly exposed to the external environment, thereby extending the service life of the electric heating fabric 100 and improving the wash fastness of the electric heating fabric 100 . In some embodiments, the covering rubber may be an insulating and high-temperature-resistant material such as polyimide, and the rubber film may be an insulating and high-temperature-resistant material such as polyethylene terephthalate or polyurethane. In some embodiments, the adhesive film can be penetrated by heat pressure to fix the covering rubber to the electric heating fabric 100 .

The electric heating fabric 200 in Figure 2 is formed by two electric heating fabrics 100 in Figure 1 connected in parallel laterally. In more detail, the two electric heating fabrics 100 in Figure 1 are connected to each other through one of their respective extension areas 170 to form the electric heating fabric 200 in Figure 2 , and the interconnected extension areas 170 further form the electric heating fabric in Figure 2 Body area 210 of 200.

在以下敘述中，將列舉本揭露多個實施例的電熱織物來驗證本揭露的功效。詳細而言，實施例1至實施例5的電熱織物依序包括如第4圖至第8圖所示的結構。具體而言，各實施例的電熱織物中有關於彎折部、孔洞結構以及緩衝區域的配置如表一所示。在本實驗例中，分別對實施例1至實施例5的電熱織物進行整體平均溫度以及其發熱區的平均溫度的測量，並計算兩者間的差值(以下簡稱為溫度差值)，以驗證本揭露的功效。各實施例所測得的溫度差值如表一所示。 In the following description, electric heating fabrics according to multiple embodiments of the present disclosure will be listed to verify the efficacy of the present disclosure. In detail, the electrothermal fabrics of Examples 1 to 5 include structures as shown in Figures 4 to 8 in order. Specifically, the configuration of the bending portion, hole structure and buffer area in the electrothermal fabric of each embodiment is as shown in Table 1. In this experimental example, the overall average temperature and the average temperature of the heating area of the electric heating fabrics from Examples 1 to 5 were measured, and the difference between the two (hereinafter referred to as the temperature difference) was calculated, so as to Verify the effectiveness of this disclosure. The temperature differences measured in each embodiment are shown in Table 1.
由實施例1至3可以看出，平弧型的彎折部相較於半圓型的彎折部可使電熱織物具有較小的溫度差值，而蘑菇型的彎折部相較於平弧型的彎折部又可使電熱織物具有更小的溫度差值，顯示蘑菇型的彎折部可使電熱織物具有較佳的熱均勻性。由實施例1及4可以看出，菱形的孔洞結構相較於長方形的孔洞結構可使電熱織物具有較小的溫度差值，顯示菱形的孔洞結構可使電熱織物具有較佳的熱均勻性。由實施例1及5可以看出，當緩衝區域不具有任何孔洞結構時，電熱織物可具有較佳的熱均勻性。 It can be seen from Examples 1 to 3 that the flat arc-shaped bending part can make the electric heating fabric have a smaller temperature difference compared with the semi-circular bending part, and the mushroom-shaped bending part can make the electric heating fabric have a smaller temperature difference than the flat arc-shaped bending part. The mushroom-shaped bending part can make the electric heating fabric have a smaller temperature difference, which shows that the mushroom-shaped bending part can make the electric heating fabric have better thermal uniformity. It can be seen from Examples 1 and 4 that the rhombus hole structure can make the electric heating fabric have a smaller temperature difference than the rectangular hole structure, indicating that the rhombus hole structure can make the electric heating fabric have better thermal uniformity. It can be seen from Examples 1 and 5 that when the buffer area does not have any hole structure, the electric heating fabric can have better thermal uniformity.
根據本揭露上述實施方式，電熱織物包括本體區以及多個發熱區，其中發熱區具有孔洞結構，且相鄰的發熱區間具有間隔，又間隔在發熱區連接於本體區處具有彎折部。透過孔洞結構及彎折部的配置(例如，位置及形狀等)，電熱織物可提供均勻分布的熱。此外，透過緩衝區域的配置，電熱織物的熱均勻性更可進一步提升。另外，透過披覆膠皮的配置，電熱織物可提供良好的保溫性能，並可具有長的使用壽命。因此，本揭露的電熱織物可提供均勻分布的熱，從而提供穿戴者舒適的使用體驗。 According to the above embodiments of the present disclosure, the electric heating fabric includes a body region and a plurality of heating regions, wherein the heating region has a hole structure, and adjacent heating regions have intervals, and the intervals have bending portions where the heating regions are connected to the body region. Through the hole structure and the configuration of the bending parts (for example, position and shape, etc.), the electric heating fabric can provide evenly distributed heat. In addition, through the configuration of the buffer area, the thermal uniformity of the electric heating fabric can be further improved. In addition, through the configuration of covering with rubber, the electric heating fabric can provide good thermal insulation performance and have a long service life. Therefore, the electrothermal fabric of the present disclosure can provide evenly distributed heat, thereby providing a comfortable user experience for the wearer.
