DETAILED DESCRIPTION OF THE INVENTION

The further description is given below with embodiments and attached figures.
The present invention is a thermal sock, which adopts fabrics made of modal elastic core-spun yarn and high elastic spandex covered yarn of level 4070 or above, both of which adopt 1:1 ratio composite interweaving, and use 12-14 needle horizontal knitting method. Because of the long fiber length of the modal material, the modal fiber has better yarn strength and uniformity, and has less hairiness and a smooth surface. Compared with ordinary viscose fiber, modal fiber has better fineness and can spin finer yarn. The Modal fiber has a higher density than ordinary viscose fiber, has a smaller volume expansion rate when exposed to water than viscose fiber, and is less affected by humidity than viscose fiber. On the other hand, spandex fiber (Spandex polyurethane fiber) is composed of flexible segments and rigid segments, and has excellent extensibility and elastic recovery properties. The sock fabric of the present invention is made of the above-mentioned materials, so that the elasticity of the sock fabric of the present invention has strong extensibility in both the horizontal and vertical directions, and the wrapping feeling and wearing comfort of the sock are further improved, and the sock fabric is not easy to pilling and has good elasticity.
FIG. 1 and FIG. 2 show a thermal sock, including a foot part 1 and a boot part 2 integrally woven from fabric, both the foot part 1 and the boot part 2 have two layers, a heater 3 is arranged in the foot part 1, the heater 3 is located in the interlayer of the two layers of material and coiled, and the power cord 31 of the heater 3 extends out of one side of the boot part 2 along the interlayer. The heater 3 is arranged in the foot part 1, the heater 3 is electrified to generate heat to achieve the warmth retention effect, and the sock is a two-layer structure, the heater is put in the interlayer to prevent the heater from directly contacting the skin, and it is convenient for arranging the power cord 31, meanwhile the foot part 1 and boot part 2 of two-layer structure can increase the thickness and reduce the loss of heat, the warmth retention effect is further enhanced, the warmth retention effect and comfort are better than traditional socks, and the mobility is not influenced.
The upper end of the boot part 2 is provided with an opening 21 for the power cord 31 to extend out, the opening 21 extends into the interlayer to form a storage bag 20 for storing the power cord 31. The end of the power cord 31 is a USB Type-C connector. The boot part 2 is provided with a storage bag 20 for storing the power cord 31, when the foot does not feel cold or the sole feels overheated, the power cord 31 can be disconnected from the power supply and put in the storage bag 20 for free movement, preventing the power cord 31 from being exposed to the outside.
The boot part 2 is provided with a flap 22 to flip over the opening 21, the root of the flap 22 is arranged on one side of the opening 21, the opposite side of the opening 21 is provided with a button 23 for fastening the flap 22.
The root of the flap 22 is connected to the opening edge of the boot part 2, the button 23 is fixed to the storage bag 20. The flap 22 is provided with a perforation 6 for fastening the button 23. The flap 22 is arranged at the opening of boot part 2, after the power cord 31 is stored in the storage bag 20, the flap 22 is fastened to the button 23 to cover the opening 21 of the storage bag 20, so as to prevent the power cord 31 from dropping out of the storage bag 20.
The heater 3 is located in the toe of the foot part 1, the heater 3 surrounds the human toes. As the toes are located in the tail end of sole, the cold feeling is mainly from the toes. Therefore, the wave type heater 3 is coiled two turns round the toes, so that the heating region is only in the tiptoe, the whole sole will not feel cold, and it is unnecessary to arrange the heater at the sole, the number of heaters is reduced, the potential safety hazard is reduced, the operational safety is enhanced, and the material consumption and cost are reduced.
The foot part 1 is provided with an elastically extensible first stretching part 4. The boot part 2 is provided with a second stretching part 5 and a third stretching part 7 which are elastically extensible. The tensile first stretching part 4, second stretching part 5 and third stretching part 7 are arranged in the foot part 1 and boot part 2 respectively, convenient for different people to wear, fit for different sole sizes, the universality is very high.
The first stretching part 4 is located in the middle of sole, the second stretching part 5 is located in the joint of boot part 2 and foot part 1, the third stretching part 7 is located in the welt of boot part 2. The first stretching part 4 is located in the middle part of sole, two of them are arranged in parallel, so that the foot part 1 can be stretched uniformly during wearing, preventing the foot part 1 from being folded after the sock has been worn for several times, so as to avoid the foot part 1 failing to be restored from excessive stretching, influencing the wear comfort; the second stretching part 5 and the third stretching part 7 are arranged at both ends of boot part 2 respectively, so that the length of boot part 2 can be adjusted during wearing; wherein the second stretching part 5 is located in the joint of boot part 2 and foot part 1, the heel part can be worn correctly by stretching, preventing the heel from offsetting, guaranteeing the comfort. The third stretching part 7 is located at the opening at the upper end of boot part 2, for adjusting the height after wearing. Secondly, the first stretching part 4, the second stretching part 5 and the third stretching part 7 not only can extend the length of the sock, but also can extend the width of the sock. Therefore, the socks can fit different foot sizes, the universality is high, and the application area is large.
The foot part 1 and boot part 2 are made of purified cotton and formed integrally. The foot part 1 and boot part 2 are woven by the flat knitting machine into an integrated planar piece, and then the flaky foot part 1 and boot part 2 are knitted into a tubular sock. In this patent, the foot part 1 and boot part 2 are knitted from well elastic cellucotton to obtain better elasticity, so that the cellucotton has a certain elongation after it is knitted by the flat knitting machine. Therefore, the length of foot part 1 and boot part 2 can be stretched 1.25 times, the width of foot part 1 and boot part 2 can be stretched 1.2 times, the comfort is enhanced.
The first stretching part 4 includes at least two stretching bands in parallel, there are at least two turns of the heater 3 in parallel, and the heater 3 is arranged in wavy line. The heater 3 is arranged in wavy line, so that the heat generated by the heater 3 can be emitted better, the heating is fast, the effect is good. Secondly, to easily find the location of heater, the foot part 1 is provided with a fringe pattern corresponding to the region of heater 3, the pattern of wavy lines can enhance the esthetics of socks, fitting different groups.
To sum up, in the use of the present invention, the sock is fitted over the foot, the sole is fully wrapped in the foot part 1 by adjusting the first stretching part 4, and the boot part 2 is adjusted to an appropriate height by stretching the second stretching part 5 and the third stretching part 7. When the sole does not feel cold, the power cord 31 is put in the storage bag 20 to avoid the power cord 31 influencing the mobility. When the sole feels cold, the power cord 31 is taken out of the storage bag 20 and powered on, the heater 3 is electrified to generate heat, so as to warm up the sole.
