Research has shown that the most important functions of athletic undergarments are their comfort and sweat control capabilities. When people sweat during exercise, the body temperature of a human body rises, hot air exists in a microclimate environment between the human body and underwear, if the outside air is cold, the hot air and the outside cold air form convection, and the underwear is naturally condensed into water due to temperature difference; meanwhile, a large amount of sweat can be generated by the human body during movement, if the sweat cannot be discharged outside the clothes in time, the heat of the human body can be taken away by the evaporation of the sweat, and the human body can feel wet and cold. Therefore, in outdoor activities, especially in some extreme environments, extreme sports or high altitude areas, the functional requirements on outdoor underwear are very high, and besides the requirement of the outdoor underwear for warm keeping, the outdoor underwear further needs to have the functions of timely and quickly absorbing sweat and quickly dissipating moisture, so that the concept of differential moisture conduction appears in the market of outdoor products. The fabric with the different moisture-conducting capacities is characterized in that the front surface and the bottom surface of the fabric have different moisture-conducting capacities, so that liquid water (sweat) can be more conveniently transferred from one side with the weak moisture-conducting capacity of the fabric to one side with the strong moisture-conducting capacity in the actual use process of the fabric, and the effects of moisture absorption, sweat releasing and moisture absorption and quick drying are achieved.

Other parts of the underwear are made of breathable flame-retardant fabric. The beneficial effects are that: the firefighter underwear has the advantages of good moisture absorption effect, quick volatilization, good flame retardant, antibacterial and deodorizing effects and good skin affinity, and can effectively control the adhesive feeling caused by sweating during sports, so that the firefighter can wear more comfortably and healthily; the underwear is seamless underwear, various tissue structures can be woven on the same plane, and the continuous weft knitting weaving process enables the garment pieces to have stronger elasticity and enhances the wearing comfort.
Patent application CN201620481134.4, "a one-way moisture-guiding functional seamless underwear" discloses that the skin-contacting surface of the underwear adopts rib texture and tuck texture to compound, forming a honeycomb mesh concave-convex structure, having a sunken one-way moisture-guiding channel and a protrusion, the outer side of the underwear is a plain texture surface. The underwear has the functional characteristics of one-way moisture conduction, moisture absorption and quick drying, light weight, environmental protection, fit and comfort and the like, can quickly absorb sweat, quickly siphons the sweat to the outer side, and can ensure that the human body is always in a dry and comfortable state because the sweat cannot seep back.
The patent application (application number: 20181108955.9) "a fabric and dress with differential moisture-conducting function", disclose that the water-transporting capacity of the fabric bottom surface and the surface are different, realize the differential water-conducting, the water-conducting of the surface contacting with human skin is weaker, difficult to wet, as little as possible diffusion, keep the dry and comfortable feeling when wearing, the water-conducting of the surface is stronger, easy to be wetted, the diffusion is fast, volatilize fast, thus make the fabric keep the skin fresh and cool and clear, have improved the travelling comfort.

wherein: r isYIs a yarn capillary single-gauge radius; theta is a contact angle between the surface of the yarn and liquid; n isYThe amount of capillary tubes is the total amount of the yarn, so that the corresponding water conductivity can be obtained.
The following is an example.
The fabric is woven by a seamless underwear weaving machine and comprises three kinds of yarns, wherein the specification of yarn Y1 is PES 75D/36F SD DTY elastic yarn, the specification of yarn Y2 is PA 650D/48F/2 SD DTY, the specification of yarn Y3 is PES 30D/24F SD DTY single-package PU 20D, the attached figure 2 is a looping structure model diagram of the cross section of the seamless underwear in the invention example, the fabric is woven by yarn Y1 and yarn Y2 in an interweaving mode, loop columns of Y1 and Y2 form a clothing surface of the fabric, sinker arcs of Y1 and Y2 form a skin-facing surface of the fabric, and yarn Y3 participates in weaving and is distributed in the middle layer of the fabric. The coil models are arranged in the longitudinal direction of the fabric in a diagonal or vertical bar mode to form the appearance of a variable diagonal pattern.
A plane constituted by the yarn was formed by closely winding the yarn on a carrier sheet for microscopic examination, and then water was dropped on the plane by a contact angle measuring instrument, and the contact angle θ thereof was measured.
In this example, yarn Y1 (model number PES 75D/36F) has a contact angle of 62 degrees, yarn Y2 (model number PA 650D/48F/2) has a contact angle of 55 degrees, and the polyester density is 1360000g/m3The density of the nylon is 1150000g/m3。
The equivalent radius of the yarn Y1 specification 75D/36F polyester monofilament is
Equivalent radius r of capillaryY1＝0.227RY1＝1.67(μm)
The total amount of capillaries of the round 75D/36F terylene single yarn can be conveniently calculated
I.e. the water conductivity LY1 ═ n of the yarn Y1Y1*rY1cosθY1＝24.22
Similarly, yarn Y2 with 50D/48F/2 nylon monofilament equivalent radius
Equivalent radius r of capillaryY2＝0.227RY2＝2.67(μm)
Can conveniently calculate the total capillary amount of 50D/48F/2 nylon single yarn
I.e. the water conductivity LY2 ═ n of the yarn Y1Y2*rY2cosθY2＝125.23
Number of loops C occupied by yarn in unit area of fabric1＝3，C2＝1,C3＝3,C 41 is ═ 1; the yarn occupies the loop length L1＝2lY2＝2*3.606dY2,L2＝2lY1＝2*3.606dY1,L3＝wY1＝4dY2,L4＝wY2＝4dY2。
Thus, it is possible to obtain:
S1＝C1*L1*dY2＝6*3.606*(100/9000/1150000)2＝2.09*10-14m2；
S2＝C2*L2*dY1＝2*3*3.606*(75/9000/1360000)2＝0.44*10-14m2；

S4＝C3*L3*dY2＝4*(100/9000/1150000)2＝0.39*10-14m2。
the specific value of the water conductivity of the two sides in the unit area of the fabric is as follows:
figure 4 is a test of the liquid moisture management properties of a standard AATCC 195 textile for a seamless undergarment bodice designed according to an example of the present invention. The measured one-way transport capacity owtc (one way transport capacity) of the fabric is 163.
