Referring to fig. 1 to 3, the present utility model provides a double-sided underwear, comprising an underwear body 1, wherein the underwear body 1 comprises a fluff layer 11, a bacteriostatic skin-friendly layer 12, a thermal layer 13, an elastic layer 14 and a cool ventilation layer 15 which are woven into a whole from top to bottom. When the temperature is low, a consumer (user) can press the thermal insulation layer 13 close to the skin, so that a thermal insulation effect is achieved; when the temperature is higher, the consumer can press the cool breathable layer 15 close to the skin, so that a cool feeling is achieved, namely, one piece of underwear can meet flexible wearing collocation in varied seasons, and fashion and extreme wearing experience are presented. In addition, each functional layer is connected together through weaving mode, avoids using technologies such as coating, compound to influence surface fabric ventilation travelling comfort.

The underwear with two sides is of a weft knitting multilayer structure, and the gram weight of the fabric of the underwear body 1 is 250-400g/m ². Specifically, the nap layer 11 is formed by sanding the skin-friendly superfine fibers of the antibacterial skin-friendly layer 12 to obtain ultra-soft nap, and the nap layer 11 is directly attached to the skin, so that the comfort of the underwear is improved.

The antibacterial skin-friendly layer 12 is woven by cotton/lyocell/polyimide fiber blended yarns. The antibacterial skin-friendly layer 12 comprises 50-95% of cotton fibers, 0-40% of lyocell fibers and 0.1-20% of polyimide fibers in percentage by mass. Wherein, the lyocell adopts 0.6-1.0dtex superfine lyocell fiber with the length of 35-40mm; the fineness of the cotton fiber is 1.11-1.43dtex, and the length is 33-50mm; the fineness of the polyimide fiber is 1.3-1.7dtex, and the length is 35-40mm; the yarn count range (i.e., the yarn fineness range of the cotton/lyocell/polyimide fiber blend yarn) of the bacteriostatic skin-friendly layer 12 is 40-100s. The cotton and polyimide fibers have certain warmth retention property, the superfine lyocell fibers can improve the softness of the handfeel of the fabric and the velvet feeling after velvet, meanwhile, the polyimide is proved to have good biocompatibility, the fabric is safe and friendly to human bodies, the polyimide fibers with specific proportions can endow the fabric with far infrared health care function and antibacterial function, and the low-proportion addition of the polyimide fibers does not influence the comfort of the underwear body 1. The antibacterial skin-friendly layer 12 can effectively reflect heat emitted by a human body, inhibit bacterial growth, reduce itch, peculiar smell and the like caused by bacterial metabolism on skin stimulation.

The thermal insulation layer 13 is woven by acrylic fiber/polyimide fiber blended yarn. The addition ratio of the acrylic fiber to the polyimide fiber in the thermal insulation layer 13 is 100-0:0-100% according to the mass fraction of the fiber. Wherein the fineness of the acrylic fiber is 0.6-1.5dtex, and the length is 35-40mm; the fineness of the polyimide fiber is 1.3-1.7dtex, and the length is 35-40mm; the yarn count range of the thermal layer 13 is 50-120s. On one hand, the thermal insulation layer 13 has good thermal insulation effect, and the thermal insulation performance of the underwear body 1 is further improved; on the other hand, the thermal layer 13 does not directly adhere to the skin, and the comfort of the underwear body 1 is not affected while the thermal upgrade is ensured. When the content of polyimide fiber is 0, the thermal insulation layer 13 is woven by acrylic yarns; when the acrylic fiber content is 0, the thermal insulation layer 13 is woven by polyimide yarns. The heat preservation layer 13 locks the heat of the human body reflected by the antibacterial skin-friendly layer 12 through the air with the flow limiting function inside, thereby enhancing the heat preservation effect.

The elastic layer 14 is woven by high-elastic fiber filaments, and the elastic layer 14 endows the underwear body 1 with certain elasticity, so that the comfort level of the underwear body is further improved. Preferably, the high elastic fiber filaments comprise one of spandex elastic fiber filaments, polybutylene terephthalate fiber filaments (PBT) or T400 fiber filaments, and the fineness of the high elastic fiber filaments is 20-75D.

The cool air-permeable layer 15 is woven by using cross-linked lyocell/polyimide fiber blended yarn. The addition ratio of the cross-linked lyocell fiber to the polyimide fiber in the cool air permeable layer 15 is 70-95 percent and 0-30 percent according to the mass fraction of the fiber. Wherein the fineness of the crosslinked lyocell fiber is 0.6-1.4dtex, and the length is 35-40mm; the fineness of the polyimide fiber is 1.3-1.7dtex, and the length is 35-40mm; the yarn count of the cool air-permeable layer 15 ranges from 40 to 100s. The cool and breathable layer 15 adopts skin-friendly fiber with cool feeling, and can be used as a skin-adhering layer, so that consumers can produce wearing experiences with different body temperature sensitivity when seasons change.

The two-sided wear undergarment also includes an antistatic layer 16 disposed between the elastic layer 14 and the cool breathable layer 15. The antistatic layer 16 is woven by graphene nylon fiber filaments or graphene nylon staple yarns. When the antistatic layer 16 is woven by graphene nylon fiber filaments, the filament titer is 40-100D; when the antistatic layer 16 is woven by graphene nylon staple yarns, the fineness of the fibers is 0.5-3dtex, and the yarn count range is 50-120s. The antistatic layer 16 can effectively relieve the static problem brought by the thermal insulation layer 13.

Therefore, the fineness of the yarns of the thermal insulation layer 13 and the antistatic layer 16 is smaller than that of the antibacterial skin-friendly layer 12 and the cool ventilation layer 15, and the arrangement can improve the wearing comfort; and the bottom exposing phenomenon of the thermal insulation layer 13 and the antistatic layer 16 in the weaving process can be avoided. The arrangement is such that the heat insulating layer 13 and the antistatic layer 16 are brought into contact with the skin as little as possible, and the wearing comfort is maintained while the heat insulating effect is enhanced. In addition, the skin-sticking functional layer endows the double-sided underwear with additional health care functions such as antibiosis, far infrared and the like.

In some embodiments, in order to improve the breathability of the two-sided underwear, the underwear body 1 is provided with ventilation holes penetrating through the fluff layer 11, the antibacterial skin-friendly layer 12, the thermal insulation layer 13, the elastic layer 14, the cool ventilation layer 15 and the antistatic layer 16, and the ventilation holes are uniformly arranged. In actual production, the ventilation holes can be selectively arranged on one layer or a plurality of layers. The pore diameter of the air holes is 5-20 μm.

As shown in fig. 1 and 2, the two-sided wear undergarment further includes a collar 2 provided on the undergarment body 1. The collar 2 is provided with decorations, so that the consumer can expose the collar 2 when wearing the garment to increase the beauty. The ornament on the collar 2 is identical on both sides, so that it is possible to realize two-sided wearing. In some embodiments, the undergarment body 1 is of a low round collar design.

As shown in fig. 2, in some embodiments, a first elastic band 3 is provided under the undergarment body 1, and a second elastic band 4 is provided at the cuff of the undergarment body 1. The presence of the first elastic band 3 and the second elastic band 4 does not affect the wearing comfort of the double-sided undergarment and the overall aesthetic appearance.

The joints of the underwear body 1 and the collar 2, sleeves, the first elastic band 3 and the second elastic band 4 are spliced seamlessly by a flat seaming machine.
