As shown in fig. 1, the manufacturing method of the electrocardio-coat comprises the following steps:
s10: weaving the garment body 10 and the fabric electrodes 20 on a loom;
in this step, as shown in fig. 4, the garment body 10 and the fabric electrode 20 are woven by a seamless integrated loom, the garment body 10 can be woven from top to bottom or from bottom to top, when weaving the garment body 10 and the fabric electrode 20, the routing parameters of the garment body 10, the position of the fabric electrode 20 and the routing parameters are preset on the seamless integrated loom, wherein the routing parameters of the garment body 10 and the routing parameters of the fabric electrode 20 can be set correspondingly according to actual needs. Of course, the garment body 10 and the fabric electrodes 20 may be woven by other weaving machines. The garment body 10 is a tubular body formed by annularly weaving a plurality of groups of non-conductive yarns 101 through an integrated weaving machine, and can be designed into a vest, a long-sleeve, a short-sleeve or a female underwear as required. As shown in fig. 4, the garment body 10 is of a vest structure. Each set of non-conductive yarns is made up of a plurality of non-conductive yarns 101. Specifically, the non-conductive yarn 101 is made of one or more materials selected from spandex, nylon, polyester and cotton, the garment body 10 in the embodiment is made of 49wt% of nylon, 48wt% of polyester and 3wt% of spandex, the garment body 10 made of the non-conductive yarn has elasticity, and when a user wears the garment, the garment body 10 can be tightly attached to the skin of the user, so that the wearing comfort of the user is improved.
The fabric electrode 20 is a block structure, the fabric electrode 20 is woven by a plurality of groups of conductive yarns 201, each group of conductive yarns 201 is made of a plurality of conductive yarns 201, each conductive yarn 201 can be made by various methods, for example, the conductive yarns 201 can be made by plating conductive materials on the surface of fibers, wherein the fibers can be made of polyamide fibers of pre-oriented yarns, draw textured yarns or fully drawn yarns. The conductive material can be selected from one or more of silver, copper, nickel and gold in combination, so that the conductive material has conductive performance.
In the embodiment, the conductive yarn is prepared by selecting the pre-oriented yarn nylon as the fiber and selecting the silver as the conductive material, and the preparation process of the conductive yarn comprises degreasing, coarsening, sensitizing, activating, depositing and elasticizing. The method comprises the following specific steps:
(1) Oil removal: degreasing the pre-oriented yarn chinlon by using sodium hydroxide, an emulsifier alkylphenol polyoxyethylene ether, clothes washing and the like;
(2) Coarsening: soaking the deoiled pre-oriented yarn chinlon in a mixed solution of sodium hydroxide and deionized water for more than 30min, and then cleaning;
(3) Sensitization: dissolving stannous chloride in a hydrochloric acid solution, adding the coarsened pre-oriented silk chinlon, stirring and washing with water;
(4) And (3) activation: adding silver nitrate solution into ammonia water, then adding sensitized pre-oriented silk polyamide, stirring and cleaning;

(6) Elasticizing: and (3) performing texturing treatment on the deposited pre-oriented yarn and nylon to ensure that the elastic-to-draw ratio is below 1.5, thus obtaining the conductive yarn.
In some embodiments, the conductive yarn 201 may be made by plating silver on a surface of an elastic nylon, wherein the elastic nylon is selected as the fiber to make the conductive yarn 201 elastic. When a human body wears the electrocardio-suit, the fabric electrodes can be stretched together with the suit body 10, so that foreign body sensation is reduced, and the wearing comfort is improved. In addition, in order to ensure the conductive performance of the conductive yarns 201, the resistance of each group of conductive yarns 201 is controlled to be less than 15 ohm/cm by controlling the area of each group of conductive yarns 201, thereby improving the reliability of the fabric electrode 20.
S20: when the fabric electrode 20 is woven to a preset position, the fabric electrode 20 is interwoven with the garment body 10;
in this step, as shown in fig. 6, when the fabric electrode 20 is woven to a predetermined position, the fabric electrode 20 is interwoven with the garment body 10 into a single body. The fabric electrode 20 forms an electrocardiosignal acquisition part 21 on one side of the clothes body 10 close to the skin, the fabric electrode 20 forms a connecting part 22 on one side of the clothes body 10 far away from the skin, the electrocardiosignal acquisition part 21 and the connecting part 22 jointly form the fabric electrode 20, and the electrocardiosignal acquisition part 21 is used for acquiring electrocardiosignals of a human body; the connecting portion 22 is used for connecting with the garment body 10. In this embodiment, the fabric electrode 20 is woven by a plurality of sets of conductive yarns 201, and the electrocardiographic signal acquisition portion 21 and the connection portion 22 are integrally formed by the conductive yarns 201.
The method of interweaving the fabric electrode 20 with the garment body 10 is as follows: the fabric electrode 20 and the clothes body 10 are interwoven together by a weft knitting process by adopting a plurality of groups of conductive yarns 201 as bottom yarns and a plurality of groups of non-conductive yarns 101 as surface yarns.
Specifically, as shown in fig. 7 and 8, when the fabric electrode 20 is interlaced with the garment body 10, the garment body 10 is woven from a plurality of sets of non-conductive yarns 101, and at the same time, the conductive yarns 201 are interlaced with the non-conductive yarns 101. In this embodiment, in the same row, on the side closer to the skin, the conductive yarn 201 is interwoven with the non-conductive yarn 101 in synchronization with every other at least one row of stitches, and on the side further from the skin, the conductive yarn 201 is interwoven with the non-conductive yarn 101 in synchronization. The conductive yarn 201 is interwoven with the non-conductive yarn 101 which is separated by at least one transverse line of coils at the side close to the skin, so that the conductive yarn 201 between the transverse line of coils of two adjacent non-conductive yarns 101 which are interwoven with the conductive yarn 201 in the same transverse line forms a non-interwoven part which is in an arc shape in a natural state, and the non-interwoven part is not interwoven with the non-conductive yarns 101 and is in a fluffy state, namely the non-interwoven part protrudes out of the surface of the clothes body 10 close to the side close to the skin. Specifically, the number of the transverse coils which are synchronously interwoven by the conductive yarn 201 and the non-conductive yarn 101 at intervals can be set according to actual needs, and only the sufficient contact between the conductive yarn 201 and the skin is required to be ensured, so that the electrocardiosignal acquisition part 21 has good electrocardiosignal acquisition capacity and the wearing comfort is ensured. On the side far from the skin, the part where the conductive yarn and the non-conductive yarn 101 are synchronously interwoven forms an interweaving part which is in a reverse V-shaped structure. Because the conductive yarn 201 is synchronously interwoven with the non-conductive yarn 101, the conductive yarn 201 on the side far away from the skin is in the same plane with the clothes body 10.
When one fabric electrode 20 is woven at a preset position, a plurality of non-woven parts in the area of one fabric electrode 20 form the electrocardiosignal acquisition part 21, and a plurality of woven parts in the area of one fabric electrode 20 form the connection part 22. The electrocardiosignal acquisition part 21 protrudes out of the surface of the garment body 10 close to the skin, so that the contact area of the electrocardiosignal acquisition part 21 and the skin of a human body is greatly increased, and the electrocardiosignal acquisition capacity of the fabric electrode 20 can be improved. The connecting part 22 and the surface of the side of the coat body 10 far away from the skin are positioned on the same plane, so that the aesthetic property of the electrocardio-coat is improved. In some embodiments, the connecting portion 22 may be configured to be a circle, an oval, a polygon, or a pattern, etc. as needed, and only the routing method between the conductive yarn 201 and the non-conductive yarn 101 needs to be changed, so as to meet the personalized requirements of the user.
In some embodiments, the color of conductive yarn 201 may or may not be the same as the color of non-conductive yarn 101. Preferably, the color of the conductive yarn 201 is different from the color of the non-conductive yarn 101, so that the connecting part 22 forms a contour on the surface of the garment body 10 on the side away from the skin, and the contour can be set to be a circle, a polygon or a pattern required by a user according to needs, thereby further improving the aesthetic property of the garment and meeting the personalized needs of the user.
In some embodiments, at the fabric electrode 20 in a predetermined position, a channel is formedControlling the number ratio of the conductive yarns 201 to the non-conductive yarns 101 to be greater than or equal to 1 2 . Experiments show that the area of each fabric electrode 20 is more than 1cm 2 And when the fabric electrode 20 is interwoven with the garment body 10, the number ratio of the conductive yarns 201 to the non-conductive yarns 101 is greater than or equal to 1. For example, an electrocardiographic vest comprises 8 rectangular fabric electrodes 20, the rectangular fabric electrodes 20 having an area of 2cm 2 . The area of the fabric electrode 20 can be set according to the size of the electrocardio-coat or different objects of users.
S30: weaving a conductive mesh belt 30, and connecting one end of the conductive mesh belt 30 with the fabric electrode 20;
in this step, as shown in fig. 4, a conductive mesh tape 30 is first woven, one end of the conductive mesh tape 30 is electrically connected to the fabric electrode 20, and the other end thereof is a free end. The conductive braid 30 is used for transmitting the electrocardiosignals collected by the fabric electrode 20 to an external electrocardio control device. The number of the conductive mesh belts 30 is the same as the preset number of the fabric electrodes 20, and if the number of the conductive mesh belts is ten, each fabric electrode 20 transmits the acquired electrocardiosignals to the external electrocardio control device through different conductive mesh belts 30. In another embodiment, the number of the conductive mesh tapes 30 can be larger than the preset number of the fabric electrodes 20, that is, a plurality of conductive mesh tapes 30 can form a group of conductive mesh tapes, and each fabric electrode 20 is connected with the external ecg control device through a different group of conductive mesh tapes 30. In this embodiment, the conductive mesh belt 30 is an elastic conductive mesh belt, and is disposed on the surface of the clothes body 10 on the side close to the skin, and when the user wears the clothes, the conductive mesh belt 30 can be stretched along with the clothes body 10, so as to reduce the foreign body sensation and improve the wearing comfort.
Specifically, the conductive mesh belt 30 is formed by interweaving a plurality of groups of conductive yarns 201 and a plurality of groups of spandex, wherein each group of conductive yarns 201 is made of a plurality of conductive yarns 201, the conductive yarns 201 can be formed by adding a metal coating on the outer surface of fibers, the fibers can be made of nylon of pre-oriented yarns, draw textured yarns or fully drawn yarns, and the metal coating can be made of copper, silver, gold, nickel and other metals. The obtained conductive yarn 201 is further interlaced with spandex to be subjected to texturing treatment, so that the texturing draw ratio is below 1.5.
In some embodiments, the ratio of the number of conductive yarns 201 to the number of spandex in the conductive braid 30 is 80 to 92: 20-8, the resistance of each group of conductive yarns 201 is less than 15 ohm/cm, the width of the prepared conductive mesh belt 30 is 2-10 mm, the length of each conductive mesh belt 30 is 5-100 cm, and the resistance of the conductive mesh belt 30 is less than 50 ohm/m, so that when the conductive mesh belt 30 is connected with the fabric electrode 20, the low impedance of the conductive mesh belt 30 can be ensured, and the connection between the fabric electrode 20 and external electrocardio control equipment is stable and reliable. Specifically, as shown in fig. 4, the routing manner of the conductive mesh belt 30 on the surface of the garment body 10 close to the skin can be set according to actual needs, and only the length of the conductive mesh belt is 5-100 cm. The conductive mesh tape 30 is preferably arranged on the surface of the garment body 10 close to the skin in a simple and beautiful manner.
In some embodiments, one end of the conductive mesh tape 30 can be fixed and electrically connected to the cardiac signal acquisition portion 21 of the fabric electrode 20 by means of bonding, sewing or hot pressing.

Preferably, the hot pressing temperature is 170 ℃ and the hot pressing time is 30 seconds. By hot-pressing the conductive braid 30 and the fabric electrode 20, the operation is simple and convenient, and the reliability of the connection between the conductive braid 30 and the fabric electrode 20 can be ensured.
S40: the skin side of the conductive mesh tape 30 is covered with the elastic protector 50 and the other end of the conductive mesh tape 30 extends out of the elastic protector.
In this step, as shown in fig. 4, the side of the conductive mesh belt 30 close to the skin is covered with the elastic protection member 50, so that the conductive mesh belt 30 is fixed between the elastic protection member 50 and the garment body 10, and the other end of the conductive mesh belt 30 extends out of the elastic protection member 50, so as to facilitate the connection between the conductive mesh belt 30 and the external ecg control device. The elastic protector 50 is used to ensure that the conductive mesh belt 30 is stably installed and isolated from the skin of the human body, thereby ensuring the safety and reliability of the conductive mesh belt 30. The conductive mesh belt 30 is fixed by the elastic protection piece 50, so that the routing of the conductive mesh belt 30 is simple, and the conductive mesh belt 30 cannot shift when a user wears the electrocardio-garment, thereby ensuring that the electrocardiosignal acquisition of the fabric electrode 20 is not influenced. Meanwhile, the elastic protection member 50 may be made of an elastic polyamide fabric or other elastic material, so that when a user wears the garment, the elastic protection member 50 is stretched together with the garment body 10, thereby reducing a foreign body sensation and further improving wearing comfort.
In some embodiments, the elastic protection member 50 is connected to the conductive tape 30 by hot melt adhesive, and then connected to the surface of the garment body 10 on the side close to the skin body by means of pressure and heat. Specifically, the conductive mesh belt 30 is firstly bonded to the elastic protection member 50 coated with the hot melt adhesive, and then the elastic protection member 50 bonded with the conductive mesh belt 30 is pressed on the surface of the clothes body 10 close to the skin side in a pressurizing and heating manner, and meanwhile, the end of the connecting end of the conductive mesh belt 30 and the fabric electrode 20 is pressed on the fabric electrode 20 in a hot pressing manner, so that the elastic protection member 50 is respectively connected with the conductive mesh belt 30 and the surface of the clothes body 10 close to the skin side, and the connection is convenient, fast, stable and reliable.
