Description

Technical Field

[0001] The invention relates to the field of underwear fabrics, in particular to a seamless underwear with variable stripes having moisture absorption and perspiration discharge functions. Background Art

[0002] Research shows that the most important functions of sports bras are their comfort and sweat control. When people sweat during exercise, their body temperature rises, and there will be hot air in the microclimate between the human body and the underwear. If the outside air is relatively cold, the hot air and the cold air outside will form convection, and naturally, due to the temperature difference, water will condense on the underwear. At the same time, the human body will produce a lot of sweat during exercise. If the sweat cannot be discharged to the outside of the clothes in time, the evaporation of the sweat will take away the body's heat, and the body will feel damp and cold. Therefore, in outdoor activities, especially in some extreme environments, extreme sports or high-altitude areas, the functional requirements for outdoor underwear are very high. In addition to requiring it to have a warming function, it must also have the function of absorbing sweat and dissipating moisture quickly in a timely manner. Therefore, the concept of differentiated moisture conduction has emerged in the outdoor products market. Differential moisture conduction fabric is a fabric with different moisture conduction capabilities on the front and bottom surfaces, so that the liquid water (sweat) can be more easily transferred from the side with weak moisture conduction capability to the side with strong moisture conduction capability during actual use, thereby achieving the effect of moisture absorption and sweat discharge and moisture absorption and quick drying.

[0003] Patent application CN108030155A, "A moisture-absorbing and quick-drying firefighter underwear", discloses a moisture-absorbing and quick-drying firefighter underwear, which is seamless underwear and adopts one-piece molding technology, and the sleeves are treated with raglan sleeves. The front chest, abdomen, armpits and back of the underwear are made of wicking strip fabric, which is interwoven with Kanglun fiber and nylon. Breathable flame-retardant fabric is used for other parts of the underwear. The beneficial effects are: the firefighter underwear of the present invention has good moisture absorption effect, rapid volatilization, good flame retardant, antibacterial and deodorizing effects, good skin-friendliness, and can effectively control the stickiness caused by sweating during exercise, making it more comfortable and healthy for firefighters to wear; the underwear of the present invention is seamless underwear, and a variety of tissue structures can be woven on the same plane. The continuous weft knitting weaving process makes the garment pieces have strong elasticity and enhances wearing comfort.

[0004] Patent application CN201620481134.4, "A one-way moisture-conducting functional seamless underwear", discloses that the skin-contacting layer of the underwear is a composite of ribbed tissue and tucked loop tissue to form a honeycomb mesh concave-convex structure with concave one-way moisture-conducting channels and protrusions, and the outer side of the underwear is a plain surface. The underwear has the functional characteristics of one-way moisture conduction, moisture absorption and quick drying, light weight, environmental protection, and comfortable fit. It can quickly absorb sweat and quickly siphon sweat to the outside, and the sweat will not seep back, ensuring that the human body is always in a dry state.

[0005] The patent application (application number: 20181108955.9) "A fabric and clothing with differential moisture conduction function" discloses the different water conduction capabilities of the bottom and surface of the fabric, achieving differentiated water conduction. The surface in contact with human skin has weaker water conduction and is not easy to be wetted, so it diffuses as little as possible to maintain a dry feeling when worn. The surface has stronger water conduction and is easily wetted, diffuses quickly, and evaporates quickly, so that the fabric can keep the skin fresh and clear, and improve comfort.

[0006] The above-mentioned patents related to the technology of seamless woven one-way moisture conduction all indicate that this function helps to improve the wearing comfort of the user, but due to the limitation of the tissue structure, the one-way moisture conduction effect can only be achieved in specific areas and plain weave structures. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a seamless underwear with variable stripes having the function of moisture absorption and perspiration discharge.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A variable stripe seamless underwear with moisture absorption and perspiration discharge function comprises a fabric body, wherein the fabric body comprises a skin-contacting layer, an intermediate layer and a clothing layer, wherein the fabric body comprises Y1 yarn and Y2 yarn woven in an interlaced manner to form a plurality of coils, wherein the coils comprise coil columns and settling arcs, wherein the coil columns formed by weaving the Y1 yarn and the Y2 yarn constitute the clothing layer of the fabric body, wherein the settling arcs of the coils formed by weaving the Y1 yarn and the Y2 yarn constitute the skin-contacting layer of the fabric body, wherein the Y3 yarn participates in weaving and is distributed in the intermediate layer of the fabric body, wherein the moisture conduction capacity of the Y2 yarn is greater than that of the Y1 yarn, wherein two regions A and B with different moisture transfer characteristics are arranged in the fabric body, wherein the regions A and B are located in the region between the clothing layer and the skin-contacting layer.

[0010] The ratio of the proportion of the circle column area of ​​the Y1 yarn to the proportion of the circle column area of ​​the Y2 yarn in the unit area of ​​the clothing layer is greater than or equal to 2:1, and the ratio of the proportion of the settlement arc area of ​​the Y1 yarn to the proportion of the settlement arc area of ​​the Y2 yarn in the unit area of ​​the skin-contacting layer is less than or equal to 1:1.

[0012] The area of ​​the region A and the area of ​​the region B are different.

[0013] The ratio of the capillary water conductivity of the clothing layer to the capillary water conductivity of the skin-contacting layer (S1*LPY2 +S2*LP Y1 ) / (S3*LP Y1 +S4*LP Y2 )>=2, L is the length of a coil on the corresponding use surface, LP Y1 The capillary water conductivity of Y1 yarn, LP Y2 is the capillary water conductivity of Y2 yarn.

[0014] The capillary water conductivity LP of the Y1 yarn Y1 <=30, capillary water conductivity LP of Y2 yarn Y2 >=50.

[0015] The loops knitted by the Y1 yarn and the Y2 yarn all span 2n adjacent horizontal rows, where n=1, 2, 3, ..., preferably n=1.

[0016] The clothing layer is provided with a vertical stripe and / or a diagonal stripe structure.

[0017] The yarn Y3 is woven into loops together with the yarn Y1 and the yarn Y2 and distributed in the middle layer of the fabric body. The yarn Y3 is an elastic composite yarn and is woven in a loose manner to transfer liquid water from the skin-contacting layer to the clothing layer.

[0018] The present invention adopts two yarns with different moisture conduction capabilities to design a seamless underwear with a changing striped appearance, and forms two areas with different moisture transfer characteristics on the outer surface and bottom surface of the fabric. By adjusting the water conduction capabilities and size ratios of the two areas, the difference in moisture transfer of the entire fabric is achieved, thereby forming a unidirectional moisture conduction functional fabric.

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] As attached Figure 1-4As shown, a variable stripe seamless underwear with moisture absorption and perspiration discharge function includes a fabric body, the fabric body includes a skin-contacting layer 3, an intermediate layer 2 and a clothing layer 1, the fabric body includes Y1 yarn and Y2 yarn woven in an interlaced manner to form a plurality of coils, the coils include coil columns and sedimentation arcs, the coil columns formed by weaving the Y1 yarn and the Y2 yarn constitute the clothing layer of the fabric body, the sedimentation arcs of the coils formed by weaving the Y1 yarn and the Y2 yarn constitute the skin-contacting layer of the fabric body, the Y3 yarn participates in weaving and is distributed in the intermediate layer of the fabric body, the moisture conductivity of the Y2 yarn is greater than that of the Y1 yarn, two regions A and B with different moisture transfer characteristics are provided in the fabric body, the region A and the region B are located between the clothing layer and the skin-contacting layer, the areas of the region A and the region B are different, and in the fabric body, the region A and the region B extend alternately.

[0025] The ratio of the proportion of the coil column area of ​​the Y1 yarn to the proportion of the coil column area of ​​the Y2 yarn in the unit area of ​​the clothing layer is greater than or equal to 2:1, and the ratio of the proportion of the sedimentation arc area of ​​the Y1 yarn to the proportion of the sedimentation arc area of ​​the Y2 yarn in the unit area of ​​the skin-contacting layer is less than or equal to 1:1, thereby ensuring that the sizes of area A and area B are different, forming regional structures with different moisture transfer characteristics.

[0026] The ratio S1:S2 of the coil unit area of ​​the Y2 yarn and the Y1 yarn of the clothing layer of the fabric body is the ratio of the coil column area of ​​the Y2 yarn and the Y1 yarn, and the ratio S3:S4 of the coil unit area of ​​the Y1 yarn and the Y2 yarn of the skin-contacting layer of the fabric body is the ratio of the sinker arc area of ​​the coil woven by the Y1 yarn and the Y2 yarn. The coil unit area S of the fabric body is C*L*d, where C is the number of coils occupied by the corresponding yarn in the unit area; L is the length of a coil on its use surface, and d is the corresponding yarn diameter.

[0027] The ratio of the capillary water conductivity of the clothing layer to the capillary water conductivity of the skin-contacting layer (S1*LP Y2 +S2*LP Y1 ) / (S3*LP Y1 +S4*LP Y2 )>=2. By limiting this ratio, the water transferability is ensured and the water conductivity of the fabric is improved.

[0028] The capillary water conductivity LP of the Y1 yarn Y1 <=30, capillary water conductivity LP of Y2 yarn Y2 >=50.

[0029] The loops knitted by the Y1 yarn and the Y2 yarn all span 2n adjacent horizontal rows, where n=1, 2, 3, ..., preferably n=1.

[0030] The clothing layer is provided with a vertical stripe and / or a diagonal stripe structure, and the appearance of a variable twill pattern is formed by the arrangement of the vertical stripes and the diagonal stripes.

[0031] The yarn Y3 is woven into loops with the yarn Y1 and the yarn Y2 respectively and distributed in the middle layer of the fabric body. The yarn Y3 is an elastic composite yarn and is woven in a loose manner, so that liquid water can be more easily transferred from the bottom surface of the fabric to the outer layer of the clothing.

[0032] according to Figure 2 Structural design can calculate the water conductivity ratio of the two sides per unit area of ​​the fabric as follows:

[0033]

[0034] S=C*L*d (2)

[0035] d=D / 9000 / p (3)

[0036] in:

[0037] S is the area occupied by the yarn per unit area;

[0038] C is the number of coils occupied by the yarn per unit area;

[0039] L is the length of a coil per unit area on the fabric surface;

[0040] d is the yarn diameter;

[0041] D is the yarn thickness (denier);

[0042] p is the yarn density.

[0043] Citing Wang Hui's "Analysis and Research on Loop Model of Weft Knitted Fabrics", Figure 3 The formula mentioned in the coil model is:

[0044] l=3.606d,w=4d.

[0045] in:

[0046] l is the length of a coil column;

[0047] w is the length of a coil settlement arc;

[0048] d is the yarn diameter.

[0049] For the garment layer of the fabric body, i.e. the front side, the length of one coil of yarn is the length of its coil column. One coil has two coil columns, i.e. L1 = 2l Y2 ,L2=2l Y1; For the fabric skin layer, i.e. the reverse side, the length of the yarn is the length of the coil sinking arc it occupies, i.e. L3 = w Y1 ,L4=w Y2 .

[0050] The calculation formula of yarn water conductivity is as follows:

[0051] LP Y =n Y *r Y cosθ Y

[0052] Where: r Y is the capillary radius of the yarn; θ is the contact angle between the yarn surface and the liquid; n Y is the total amount of yarn capillaries, from which the corresponding water conductivity can be obtained.

[0053] The following is an example to illustrate.

[0054] The fabric is woven on a seamless underwear loom. The fabric is made of three types of yarns. The yarn Y1 is PES 75D / 36FSD DTY elastic yarn, the yarn Y2 is PA6 50D / 48F / 2SD DTY, and the yarn Y3 is PES 30D / 24F SD DTY single-package PU 20D. Figure 2 This is a loop structure model diagram of the cross section of seamless underwear in the present invention. The fabric is woven by interweaving yarn Y1 and yarn Y2. The loop columns of Y1 and Y2 constitute the clothing layer of the fabric, the sinking arcs of Y1 and Y2 constitute the skin-contacting layer of the fabric, and yarn Y3 participates in the weaving and is distributed in the middle layer of the fabric. The loop model is arranged in the form of twill or vertical stripes in the longitudinal direction of the fabric to form a changing twill pattern appearance.

[0055] The yarn is tightly wound on a slide for microscope detection to form a plane composed of the yarn, and then water is dropped on the plane using a contact angle measuring instrument to measure the contact angle θ.

[0056] In this example, the contact angle of yarn Y1 (model PES 75D / 36F) is 62°, the contact angle of yarn Y2 (model PA650D / 48F / 2) is 55°, and the density of polyester is 1360000 g / m 3 ,Nylon density is 1150000g / m 3 .

[0057] The equivalent radius of the yarn Y1 specification 75D / 36F polyester monofilament is

[0058]

[0059] Capillary equivalent radius r Y1=0.227R Y1 =1.67(μm)

[0060] The total capillary volume of round 75D / 36F polyester single yarn can be easily calculated

[0061]

[0062] That is, the water conductivity of yarn Y1 is LY1 = n Y1 *r Y1 cosθ Y1 =24.22

[0063] Similarly, the equivalent radius of the yarn Y2 specification 50D / 48F / 2 nylon monofilament is

[0064]

[0065] Capillary equivalent radius r Y2 =0.227R Y2 =2.67(μm)

[0066] The total capillary volume of 50D / 48F / 2 nylon single yarn can be easily calculated

[0067]

[0068] That is, the water conductivity of yarn Y1 is LY2 = n Y2 *r Y2 cosθ Y2 =125.23

[0069] The number of coils occupied by the yarn per unit area of ​​the fabric is C1=3, C2=1, C3=3, C4=1; the coil length occupied by the yarn is L1=2l Y2 =2*3.606d Y2 ,L2=2l Y1 =2*3.606d Y1 ,L3=w Y1 =4d Y2 ,L4=w Y2 =4d Y2 . So we can get:

[0070] S1=C1*L1*d Y2 =6*3.606*(100 / 9000 / 1150000) 2 =2.09*10 -14 m 2 ;

[0071] S2=C2*L2*d Y1 =2*3*3.606*(75 / 9000 / 1360000)2 =0.44*10 -14 m 2 ;

[0072] S3=C3*L3*d Y1 =3*4*(75 / 9000 / 1360000) 2 =0.73*10 -14 m 2 ;,

[0073] S4=C3*L3*d Y2 =4*(100 / 9000 / 1150000) 2 =0.39*10 -14 m 2 .

[0074] The ratio of water conductivity of the two sides per unit area of ​​the fabric is:

[0075]

[0076] Attached Figure 4 The seamless underwear body designed for the present invention was tested according to the standard AATCC 195 for the liquid moisture management performance of textiles. The one way transport capability (OWTC) of the fabric measured this time was 163.
