In addition, it should be noted that the overall shape of the functional underwear may be, but is not limited to, a body-shaping garment, a brassiere, underwear, and the like.

Specifically, the electric wire 3 includes a core wire 31, a rubber cover 32, and an insulating layer 33; wherein the outer diameter of the core wire 31 is less than or equal to 10 μm, preferably 5-8 μm; the thickness of the rubber sleeve 32 is 0.05-0.3 mm, preferably 0.1-0.2 mm; the outer diameter of the whole wire 3 is 0.3-0.75 mm, preferably 0.3-0.5 mm; the wire 3 with the wire diameter can be well fused with the decorative lines on the outer layer, has no abrupt feeling, is beautiful and elegant, and has strong bending resistance.

Further, in order to improve the bending resistance, the electric wire 3 comprises at least 12 strands of core wires, the outer layer of each strand of core wire 31 is wrapped with an insulating layer, and the outer layer of the whole electric wire is also wrapped with a rubber sleeve 32; preferably, the electric wire comprises 16-20 strands of core wires, so that the electric conductivity of the electric wire is not greatly influenced under the condition that some core wires are broken, and the scrub resistance and the bending resistance are improved.

After the electric wire 3 is fused with the decorative lines, the electric wire 3 and the outer layer 2 can be fixed by adopting an embroidery process; specifically, the electric wire 3 can be sewn on the surface of the outer layer 2 by adopting a fish silk thread; more specifically, the electric wire 3 is fixed around the surface of the outer layer 2 by a fishwire. After the fixing, the electric wire does not shake in the cleaning process, so that the friction and damage of the cleaning process to the electric wire are reduced.

In addition, in order to prevent the electric wire from being damaged by pulling, rubbing and washing and other operations in the daily use process, the outer layer 2 material in the invention can be high-elasticity nylon gauze, the elasticity is high, a certain degree of tension can be eliminated in the pulling process, and the acting force on the electric wire is reduced.

It should be noted that, in the existing functional body-shaping clothes and bras, the adopted conductive wire is generally a copper wire, the wire diameter of the wire core is about 300 μm, and the overall outer diameter of the wire is about 1 mm; for pleasing to the eye and abluent convenience, generally with the electric wire setting between the intermediate layer of decorative layer and inlayer, this just makes when dressing the foreign matter sense heavier, consequently often needs to promote the thickness of inlayer for the underwear is whole heavy, and the comfort is relatively poor. In addition, the existing electric wire is not fixed in the interlayer, is easy to shake and shift during cleaning, has larger friction on the electric wire and the inner and outer layers, and ensures that the underwear is easy to wear and has short service life. According to the invention, the electric wire is fixed on the decorative outer layer and is fused with the decorative pattern of the outer layer, so that the functional underwear is attractive and elegant in appearance, the service life of the underwear is prolonged, and the feeling of wearing foreign bodies is reduced.

In addition, in order to provide the electric wire in the outer layer, it is necessary to select a material of the electric wire. Specifically, in one aspect, in the present invention, the core wire 31 is made of the following raw materials in percentage by weight: 1.5-3% of Fe, 0.5-5% of Ni, 0.5-2% of Ti, 0.05-1% of Cr and the balance of Al. The raw materials are melted, extruded and drawn to form the core wire with the wire diameter less than or equal to 10 mu m, so that the bending resistance of the core wire can be greatly improved, and the bending resistance times of the core wire can reach more than 10 ten thousand times. In addition, the core wire has strong flexibility and can be arranged on the decorative outer layer by combining with an embroidery process.

On the other hand, in the invention, the rubber sleeve is mainly prepared from the following raw materials in parts by weight:

40-60 parts of chlorinated polyethylene, 10-30 parts of ethylene propylene rubber, 10-30 parts of polyamide, 3-10 parts of a silane coupling agent, 50-80 parts of talc, 40-80 parts of calcium carbonate, 1-10 parts of dioctyl phthalate, 5-15 parts of magnesium oxide, 1-5 parts of an antioxidant and 1-10 parts of a crosslinking agent. The rubber sleeve has strong tearing resistance and excellent mechanical property; and has high flexibility.

Specifically, in the formula of the rubber sleeve, the mass fraction of chlorine in the chlorinated polyethylene is 32-38 wt%, the tensile strength is not less than 9MPa, and the elongation at break is not less than 700%; preferably, the mass fraction of chlorine in the chlorinated polyethylene is 35-37 wt%. The addition weight part of the chlorinated polyethylene is 40-60 parts, preferably 50-60 parts.

When the amount of the crosslinking agent is more than 10 parts, the elongation is greatly reduced. TAIC and silane coupling agent are mixed for use, so that reasonable crosslinking degree of chlorinated polyethylene, ethylene propylene rubber and polyamide can be fully ensured, and a rubber sleeve product with reasonable tensile strength, elongation at break, elasticity and wear resistance can be obtained.

Specifically, in the formula of the rubber sleeve, talc, calcium carbonate, dioctyl phthalate, an antioxidant and magnesium oxide are added in order to coordinate the performance of each aspect of the rubber sleeve.

Furthermore, for the sake of beauty, the formula of the rubber sleeve can also contain 1-5 parts of pigment.
