DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] Combination Figure 1 The present embodiment is described in detail. The present embodiment involves a double-layer structured warm knitted underwear, comprising a body 1 and sleeves 2; the fabrics used for the body 1 and the sleeves 2 are double-layer knitted fabrics, including an inner layer and an outer layer.

[0023] The inner layer is woven from an antibacterial moisture-conducting core-spun yarn, and the antibacterial moisture-conducting core-spun yarn includes a first core yarn 11 and a first coating fiber layer 12, wherein the first core yarn 11 includes hollow antibacterial nylon filaments, and the first coating fiber layer 12 is metallocene polypropylene fiber. The hollow antibacterial nylon filaments not only have an antibacterial effect, but also have a warming effect due to the hollow structure. The metallocene polypropylene fiber used can improve the comfort of the fabric when in contact with human skin, and the metallocene polypropylene fiber has a wicking effect, and the sweat discharge rate is nearly 8 times higher than that of polyester fiber, which can keep the user's body dry. The use of metallocene polypropylene fiber takes into account the fact that the human body will sweat in winter due to exercise or heat.

[0024] The surface layer is woven from an antibacterial core-wrapped composite yarn, which includes a second core yarn 21, a second coating fiber layer 22, a third coating fiber layer 23 and a wrapping silk layer 24 arranged in sequence; the second core yarn 21 is an antibacterial polyester filament, the second coating fiber layer 22 is an Antaibei fiber, the third coating fiber layer 23 is a Nuanyi velvet fiber, and the first wrapping silk layer 24 is a graphene-modified nylon filament. Antaibei is a modified viscose fiber with antibacterial function developed by Sateri, which is mainly used in towels, quilts, medical industries, etc.; Nuanyi velvet is a modified polyester developed by Huamao Biotechnology. The fiber has the characteristics of moisture absorption and perspiration, heat storage and temperature increase, and improvement of microcirculation. It has good antibacterial and skin care effects, can quickly remove moisture from the skin, and quickly evaporate and release. Graphene-modified nylon filament adopts a unique graphene modification technology to reduce the loss of far infrared rays, maximize the temperature increase, and has the effect of heat storage and warmth preservation.

[0025] Furthermore, the fineness of the antibacterial polyester filament is 44.4dtex / 24F, and the fineness of the graphene-modified nylon filament is 77.8dtex / 36F.

[0026] Embodiment 2

[0027] Combination Figure 4 and Figure 5, this embodiment is described in detail. The double-layer structure thermal knitted underwear involved in this embodiment is different from the first embodiment in that: a wrapping yarn layer 13 is arranged between the first core yarn 11 and the first covering fiber layer 12; the wrapping yarn layer 13 includes Viloft / polyester blended yarn and Outlast acrylic air conditioning fiber yarn wrapped around the outside of the first core yarn 11. Viloft fiber is a high-quality wood cellulose fiber. The fine grooves on the fiber surface give it good wicking performance, and a large number of micro airbags constructed by the flat cross-section can play a role in heat preservation and cold protection. Viloft fiber can form a unique moisture-conducting channel in the yarn body blended with circular cross-section polyester fiber, which plays a role in moisture regulation. Outlast acrylic air conditioning fiber is a new type of "intelligent fiber". It implants microcapsule thermosensitive phase change material in acrylic fiber. This material has the function of absorbing, storing and releasing heat in the form of latent heat energy. It can achieve heat absorption and heat release through the mutual conversion between solid and liquid during temperature changes, and play a buffering role in the change of external temperature, so that the temperature is kept within a comfortable range.

[0028] Furthermore, the Viloft / polyester blended yarn and the Outlast acrylic air-conditioning fiber yarn are spirally wound in opposite directions.

[0029] Another difference from the first embodiment is that a fourth coating fiber layer 25 is provided between the third coating fiber layer 23 and the first wrapping silk layer 24, and the fiber used in the fourth coating fiber layer 25 is EKS fiber. EKS fiber is a material for self-heating fabrics, which not only far exceeds the moisture absorption performance of natural fibers, but also has the function of moisture absorption and heat generation.

[0030] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
