Description

Technical Field

[0001] The utility model discloses a windproof composite fabric and belongs to the field of composite fabrics. Background Art

[0002] Composite fabric is a kind of fabric made of multiple layers of materials bonded together. It is generally used in textile fields such as clothing, so that the fabric can meet more functional requirements.

[0003] In order to provide a certain degree of breathability, existing fabrics often reserve pores in the fabrics through weaving or other processing methods to provide a breathable effect. However, when these pores are facing the wind, wind with greater kinetic energy will pass through the pores and directly act on the human body, causing discomfort.

[0004] In view of the above problems, a new improvement plan is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a windproof composite fabric in order to solve the above-mentioned problem.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a windproof composite fabric, including a breathable layer and a skin-contacting layer, the breathable layer and the skin-contacting layer are sewn together, a plurality of breathable holes are arranged in the breathable layer, a windproof film is compounded on the breathable layer, a plurality of weak wind cavities are formed in the windproof film, and the weak wind cavities are connected to the breathable holes and the external environment.

[0007] Preferably, the weak wind cavity includes a main channel, a first branch and a second branch, one end of the first branch and the second branch are connected to the main channel, the other end of the first branch is connected to the air hole, and the other end of the second branch has a corner and is connected to the first branch.

[0008] Preferably, the corner is in an arc shape.

[0009] Preferably, the main channel opening has a certain angle with the thickness direction of the windproof membrane.

[0010] Preferably, a plurality of protrusions are formed on a side of the skin-contacting layer away from the breathable layer, and the cross-section of the protrusions is arc-shaped.

[0011] Preferably, the skin-contacting layer is made of pure cotton material.

[0012] Preferably, the breathable layer is made of bamboo fiber material.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up a weak wind cavity, the oncoming wind is diverted in the weak wind cavity and collides and cancels each other out, thereby greatly reducing the kinetic energy of the wind and playing a certain windproof role.

[0015] 2. The weak wind cavity is connected to the air holes and the external environment, which can not only protect against wind but also provide ventilation effect, killing two birds with one stone. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] like Figure 1 As shown, a windproof composite fabric comprises a breathable layer 1 and a skin-contacting layer 2, wherein the breathable layer 1 and the skin-contacting layer 2 are sewn together, a plurality of breathable holes 3 are arranged in the breathable layer 1, the skin-contacting layer 2 is used for contacting with human skin, the breathable holes 3 on the breathable layer 1 are used for providing a breathable effect, so that the heat on the surface of human skin can be dissipated as soon as possible, a windproof membrane 4 is compounded on the breathable layer 1, the windproof membrane 4 can be made of thin film materials such as TPU and PTFE, a plurality of weak wind cavities 5 are formed in the windproof membrane 4, the weak wind cavities 5 are connected with the breathable holes 3 and the external environment, by setting the weak wind cavities 5, the kinetic energy of the oncoming wind is reduced in the weak wind cavities 5, so as to play a certain windproof role, and the weak wind cavities 5 are connected with the breathable holes 3 and the external environment, so as to play a windproof role while taking into account the breathable effect, thus killing two birds with one stone.

[0020] The weak wind cavity 5 includes a main channel 6, a first branch 7 and a second branch 8. One end of the first branch 7 and the second branch 8 are both connected to the main channel 6, the other end of the first branch 7 is connected to the air vent 3, and the other end of the second branch 8 has a corner and is connected to the first branch 7. When the wind blows head-on, the wind enters the weak wind cavity 5 through the main channel 6, and is divided into two winds in the main channel 6 that advance along the first branch 7 and the second branch 8 respectively. The wind in the second branch 8 will turn after encountering the corner and meet the wind in the first branch 7, thereby forming a collision, offsetting kinetic energy, and achieving the effect of reducing wind force. The first branch 7 is connected to the air vent 3, so the wind entering the air vent 3 is reduced and there will be no excessive kinetic energy. At the same time, the connected structure is maintained, which can provide a certain ventilation effect while preventing wind. Referring to Figure 1 As shown, the corner is in an arc shape, so the wind moving along the second branch 8 to the corner will be smoother during the turning process.

[0021] The opening direction of the main channel 6 has a certain angle with the thickness direction of the windproof membrane 4. This design can ensure that the opening of the main channel 6 will not face the blowing direction of the wind, thereby partially blocking the wind when it enters the main channel 6.

[0022] The skin-contacting layer 2 of this product is formed with a plurality of protrusions 9 on the side away from the breathable layer 1, and the cross-section of the protrusion 9 is arc-shaped. By providing the arc-shaped protrusions 9, the skin-contacting layer 2 can be made more comfortable when in contact with the skin. The skin-contacting layer 2 is made of pure cotton material, which is deeply loved by people for its many advantages such as moisture absorption, breathability, environmental protection and skin-friendliness.

[0023] Finally, the breathable layer 1 is made of bamboo fiber material, which has good moisture absorption and perspiration and breathability, which is beneficial to ensure the breathability of this product.

[0024] 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.
