During knitting, different knitting designs are performed on different regions of the initially-shaped knitted knee pad body 110 according to a preset program of a knitting machine to obtain the initially-shaped knitted knee pad 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 implanting the heating wire into the first preset part, so that the heating wire is bent at multiple positions to form a preset shape.
Specifically, as shown in fig. 2 and 3, the heating wire 120 may be inserted into the hollow space of the first predetermined portion 111 by using an elongated bald needle. Since the heating wire 120 is a flexible wire, it can be changed into a predetermined shape with a plurality of bends, which is the same as the first predetermined portion 111, after being implanted into the first predetermined portion 111.
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.

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: the original knitted knee pad main body is sewn according to the long cylindrical structure to obtain the corresponding electric heating knee pad.
Specifically, after the heating wire 120, the power cord assembly 130 and the power module 140 are respectively implanted into the knitted knee pad main body 110 in the initial shape by the above-mentioned method steps, the knitted knee pad main body 110 in the initial shape can be stitched according to a long tubular structure to obtain the corresponding electric heating knee pad 100 shown in fig. 4, wherein the electric heating knee pad 100 has a long tubular structure.
In addition, when the initially knitted knee pad body 110 is sewn according to the long tubular structure, a plurality of openings (not shown) may be formed at the sewn portions of the initially knitted knee pad body 100, that is, a plurality of openings are provided corresponding to the rear side of the electric heating knee pad 100, so that it is possible to facilitate wearing the electric heating knee pad 100 without hindering the bending of the legs.
