Description

Technical Field

[0001] The utility model discloses a breathable and sweat-absorbent non-woven fabric, belonging to the field of non-woven fabrics. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber and polyester fiber. It is made through a needle-punching process and can be made into different thickness, feel, hardness, etc.

[0003] When the existing non-woven fabric is used, the gaps between the non-woven fabric fibers are compressed due to external squeezing, and the external air cannot pass through the gaps between the non-woven fabric fibers, thereby seriously reducing the air permeability of the non-woven fabric.

[0004] A breathable and sweat-absorbent nonwoven fabric is now proposed to solve the problem that the air permeability of the nonwoven fabric is seriously reduced when it is squeezed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a breathable and sweat-absorbent nonwoven fabric.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a breathable and sweat-absorbent non-woven fabric, including a main body, which includes: a breathable layer, a support layer and a skin-contacting layer along the thickness direction, the breathable layer is hot-pressed into a waveform on the side away from the skin-contacting layer, and an air duct that runs through the main body is formed at the trough of the waveform of the breathable layer, and air strips are continuously interspersed in the air duct, and the diameter of the air strips is smaller than the diameter of the air duct.

[0007] The utility model is further configured as follows: a moisture conducting strip is arranged in the main body, both ends of the moisture conducting strip are respectively extended out of the side of the breathable layer away from the skin-contacting layer, and the middle section of the moisture conducting strip is extended out of the side of the skin-contacting layer away from the breathable layer.

[0008] The utility model is further configured as follows: a deformation part is fixedly provided in the skin-contacting layer, one end of the deformation part extends into the skin-contacting layer and is fixedly connected to the skin-contacting layer, and the other end of the deformation part extends out of the skin-contacting layer and abuts against the side of the moisture-conducting strip close to the skin-contacting layer.

[0009] The utility model is further configured as follows: both ends of the moisture conducting strip extending out of the breathable layer are fixedly provided with moisture discharging parts with a diameter larger than that of the moisture conducting strip.

[0010] The utility model is further configured as follows: the air-permeable strip is made of bamboo fiber material.

[0011] The utility model is further configured as follows: the moisture conducting strip is made of moisture absorbing and perspiration wicking fabric.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: when the product is in use, external air can flow along the corrugated surface to converge at the trough. When squeezed in the length direction, the length of the main body is reduced, and the internal gap is compressed and reduced. At this time, the main body is deformed and thickened in the thickness direction, resulting in an increase in the inclination angle of the crests and troughs on the corrugated surface of the breathable layer. External air acts on the corrugated surface, flows along the corrugated surface and converges at the trough, and blows toward the breathable strip at a high speed and high flow rate, and guides the flow along the breathable strip toward the skin-contacting layer, thereby maintaining the breathable effect of the non-woven fabric on the wearer's skin.

[0015] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] like Figure 1 As shown, a breathable and sweat-absorbent non-woven fabric of the present embodiment includes a main body, and the main body includes along the thickness direction: a breathable layer 1, a supporting layer 2 and a skin-contacting layer 3, the side of the breathable layer 1 away from the skin-contacting layer 3 is hot-pressed into a waveform, and an air duct 4 penetrating the main body is formed at the trough of the waveform of the breathable layer 1, and air strips 5 are continuously interspersed in the air duct 4, and the diameter of the air strips 5 is smaller than the diameter of the air duct 4.

[0017] When the product is in use, the wearer can wear the skin-contacting layer 3 with the side away from the breathable layer 1 close to the wearer's skin, so that the external air flow acts on the corrugated surface of the breathable layer 1, flows along the corrugated surface, and flows from the crest to the trough, so that the external air flows into the air duct 4 at a high speed and in large quantities, and directly flows to the wearer's skin surface through the air duct 4, thereby achieving a breathable effect. When the main body is squeezed in the length direction, the main body is deformed and shortened in the length direction, and deformed and thickened in the thickness direction, so that the height difference between the crest and the trough of the corrugated surface of the breathable layer 1 increases, thereby accelerating the flow rate of the air gathered at the corrugated trough of the breathable layer 1, so that the external air is filled into the breathable strip 5 and flows to the skin surface along the breathable strip 5, so that when the main body is squeezed, it still maintains a good breathable effect, solving the problem that the breathability of the non-woven fabric is seriously reduced when it is squeezed.

[0018] like Figure 1 As shown, a moisture conducting strip 6 is provided in the main body, and both ends of the moisture conducting strip 6 extend out of the side of the breathable layer 1 away from the skin-contacting layer 3, and the middle section of the moisture conducting strip 6 extends out of the side of the skin-contacting layer 3 away from the breathable layer 1.

[0019] When the product is in use, the middle section of the moisture-conducting strip 6 contacts the wearer's skin, thereby reducing the contact area between the main body and the skin, reducing the friction between the main body and the skin, and achieving a comfortable and soft wearing effect. The skin surface is only in contact with the moisture-conducting strip 6, so that the skin sweat directly contacts the moisture-conducting strip 6, thereby ensuring that the sweat is quickly absorbed and flows along the moisture-conducting strip 6 to the outside of the breathable layer 1 and away from the main body, achieving a perspiration effect.

[0020] like Figure 1 As shown, a deformation part 7 is fixedly provided in the skin-contacting layer 3, one end of the deformation part 7 extends into the skin-contacting layer 3 and is fixedly connected to the skin-contacting layer 3, and the other end of the deformation part 7 extends out of the skin-contacting layer 3 and abuts against the side of the moisture-conducting strip 6 close to the skin-contacting layer 3.

[0021] When the product is in use, one end of the deformation portion 7 extending out of the skin-contacting layer 3 always keeps in contact with the middle section of the moisture-conducting strip 6, prompting the wearer's skin to keep in contact with the middle section of the moisture-conducting strip 6 extending away from the skin-contacting layer 3, and when the main body is stretched, the main body is deformed and narrowed along the thickness direction, and the length of the moisture-conducting deformation portion 7 extending out of the skin-contacting layer 3 increases, thereby driving the middle section of the moisture-conducting strip 6 to deform and extend out of the skin-contacting layer 3 to increase, while further reducing the contact area between the moisture-conducting strip 6 and the skin, thereby increasing the comfort of wearing the product.

[0022] like Figure 1 As shown, both ends of the moisture conducting strip 6 extending out of the breathable layer 1 are fixedly provided with moisture dissipation portions 8 having a diameter larger than that of the moisture conducting strip 6 .

[0023] When the product is in use, the middle section of the moisture-conducting strip 6 touches the skin surface and quickly absorbs sweat, which is then transferred to the moisture-discharging section 8 through the moisture-conducting strip 6. Since the moisture-discharging section 8 is placed in the external air, the external air can carry the sweat in the moisture-discharging section 8 away from the main body when flowing through the moisture-discharging section 8. When the moisture-conducting strip 6 is subjected to a tensile force, the moisture-discharging section 8 abuts against the surface of the breathable layer 1 to prevent the moisture-conducting strip 6 from being pulled away from the main body, which would lead to the problem of reduced sweat absorption and moisture-discharging effect of the product.

[0024] like Figure 1 As shown, the air-permeable strip 5 is made of bamboo fiber material.

[0025] When the product is in use, due to the highly hollow interior of the bamboo fiber material, air flows into the air permeable strip 5 and can flow out of the air permeable strip 5 smoothly, thus achieving a good ventilation effect.

[0026] like Figure 1 As shown, the moisture-conducting strip 6 is made of moisture-absorbing and perspiration-wicking fabric.

[0027] When the product is in use, the moisture wicking fabric has a high specific surface area, and there are numerous pores or grooves on the surface. Its cross-section is generally a special shape. The capillary effect is used to enable the fiber to quickly absorb moisture and sweat from the skin surface. Through diffusion and transfer to the outer layer, the moisture conducting strip 6 can quickly absorb sweat from the skin surface and transfer it to the moisture discharge part 8 for moisture discharge from the main body, thereby ensuring the dryness of the wearer's skin.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
