It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, an embodiment of the present invention provides a manufacturing process of an electric heating knitted fabric, including the following steps:
step S110: and knitting an initial knitted fabric main body by using a knitting machine, wherein the initial knitted fabric main body is in a plane sheet shape with a preset structure, and a first preset part, a second preset part and a third preset part on the initial knitted fabric main body are all in a double-layer structure.
Specifically, as shown in fig. 2, the original-shaped knitted fabric main body 110 is a planar sheet with a predetermined structure, which may be a sock structure, a knee pad structure or other knitted fabric structures, and the sock structure is specifically taken as an example in the drawing. The original knitted fabric main body 110 is formed by weaving high-elasticity covering yarns and imitation mink velvet, can be woven by a common 7-needle, 9-needle or 12-needle knitting machine, and comprises the following specific material components: 22.5% of viscose, 52.5% of chinlon, 10% of terylene and 15% of spandex. The material has good elasticity, is comfortable and soft, and is suitable for knitting by a knitting machine. During knitting, different knitting designs are performed on different regions of the original knitted fabric main body 110 according to a preset program of a knitting machine, so as to obtain the original knitted fabric main body 110. The preset program includes performing jacquard cylinder knitting design on the first preset portion 111, the second preset portion 112, and the third preset portion 113, so that the first preset portion 111, the second preset portion 112, and the third preset portion 113 all form a double-layer structure, specifically, as shown in fig. 3, an upper-layer hollow space and a lower-layer hollow space are formed.
Step S120: and bending a plurality of positions of the heating wire to form a preset shape, and implanting the heating wire into the first preset position.
Specifically, as shown in fig. 2 and 3, the heating wire 120 may be bent at a plurality of positions to form a predetermined shape, and then inserted into the hollow space of the first predetermined portion 111 by using an elongated bald needle.
The heating wire 120 includes a heating wire body and a protective layer covering the heating wire body, wherein the heating wire body is a metal heating wire or a synthetic fiber heating wire or a pure carbon fiber heating wire or a synthetic carbon fiber heating wire. The protective layer is a silica gel layer or a TPU layer. Because the metal heating wire is not resistant to folding, and the diameter of the pure carbon fiber heating wire is too thick, foreign body sensation is easy to occur, the synthetic carbon fiber heating wire is preferably adopted as the heating wire main body. Meanwhile, the smell and skin allergy of the TPU layer can not reach the relevant environmental protection standard, so the silica gel layer is preferably adopted as the protective layer.

Because the heating wire 120 adopts the synthetic carbon fiber heating wire as the heating material, and the synthetic carbon fiber material can not adopt the soldering tin technology to weld, need adopt the riveting technology to carry out the conduction and connect, therefore adopt copper to detain terminal 11 and realize the electric connection between heating wire 120 and the power line, simultaneously, the outside parcel of copper detain terminal 11 has pyrocondensation pipe 12, can protect and insulate the terminal. And fix two copper button terminals 11 respectively in two different bilayer structures, make it can not contact, can effectively reduce the short circuit risk, improve its security.
In addition, because the original knitted fabric main body 110 is elastic, the heating wire 120 is a soft wire material, but has no elasticity, and a plurality of positions of the heating wire 120 are bent to form two layers of wavy shapes, the requirement of size elastic change of left and right transverse pulling can be met, and meanwhile, the vertical pulling and the vertical pulling can be compatible with the elasticity through the change of the distance between the two layers of wavy shapes. Also, the heating area and the amount of heat generated per unit area can be controlled by controlling the degree of bending of the heating wire 120 and the interval between the two layers of undulations. The heating temperature of the heating wire 120 can be controlled between 37-70 degrees centigrade by adjusting the voltage or current.
Step S140: and sewing the initial knitted fabric main body according to the preset structure to obtain the corresponding electric heating knitted fabric.
Specifically, after the heating wire 120, the power wire assembly 130 and the power module 140 are respectively implanted into the original-shaped knitted fabric main body 110 through the above-mentioned method steps, the original-shaped knitted fabric main body 110 can be stitched according to the predetermined structure to obtain the corresponding electric heating knitted fabric, in this embodiment, taking the sock structure as an example, the corresponding electric heating sock 100 as shown in fig. 4 can be obtained by stitching the original-shaped knitted fabric main body 110 according to the sock structure.
In the manufacturing process of the electric heating knitted fabric provided by the embodiment, when the electric heating knitted fabric is manufactured, an initial knitted fabric main body is knitted by a knitting machine, the initial knitted fabric main body is a planar sheet with a preset structure, and a first preset part, a second preset part and a third preset part on the initial knitted fabric main body are all of a double-layer structure.
