[0021] The drawings are only used for illustrative purposes and cannot be understood as limiting the patent; in order to better illustrate the embodiments, some components of the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

[0022] It is understandable for those skilled in the art that some known structures and their descriptions in the drawings may be omitted. The technical solutions of the utility model will be further described below in combination with the drawings and embodiments.

[0023] As shown in the drawings Figs. 1-3 An outdoor windproof fabric includes a strength layer 1, a toughening layer 2 and a waterproof and moisture-permeable film layer 3 arranged in sequence, and the strength layer 1, the toughening layer 2 and the waterproof and moisture-permeable film layer 3 are connected by hot rolling; the hot rolling connection can ensure that the fabric has good connection strength.

[0024] The toughening layer 2 is uniformly distributed with rectangular blocks 21 on one side, and multiple long strip-shaped protrusions 22 are arranged at intervals on the other side of the toughening layer 2, and a hydrophobic channel is formed between the two adjacent long strip-shaped protrusions 22; by setting the hydrophobic channel, the accumulation of water on the surface of the fabric can be avoided.

[0025] The strength layer 1 is provided with a through hole 11, the through hole 11 is integrally arranged with the strength layer 1 and the through hole 11 is arranged at a position corresponding to the rectangular block 21, and the rectangular block penetrates the through hole 11. The through hole 11 is formed by weaving, and the strength of the strength layer 1 can be avoided by punching and other methods. By the rectangular block 21 and the through hole 11, the combination of the strength layer 1 and the toughening layer 2 can be more closely, and the through hole 11 position of the strength layer 1 has greater deformation bearing capacity, which can deform together with the toughening layer 2 under external force, significantly improving the toughness of the fabric, so as to cope with the harsh outdoor environment and reduce the damage of the fabric in outdoor use. The material of the toughening layer 2 is rubber, which has good ductility. The strength layer 1 provides good tear resistance for the fabric, and the toughening layer 2 provides good stretch resistance.

[0026] In some embodiments, a plurality of air vents 23 are further arranged in the hydrophobic channel. The air permeability of the fabric can be improved by the air vents 23, and the occurrence of stuffy feeling during use can be reduced.

[0027] In some embodiments, the waterproof and moisture-permeable film layer 3 has a thickness of 100 microns and a porosity of 85%. The waterproof and moisture-permeable film layer 3 is prepared by heating and melting fine powder of PTFE to form a film, then performing rapid stretching, and then cooling to form a mesh-like micro-porous structure with a thickness of about 100 microns and a porosity of 85%. The pore size is about 1 / 20,000 of the size of a water droplet (with an average diameter of about 200 microns), but 700 times larger than the size of a water vapor molecule (with an average diameter of about 0.4 nm). Therefore, the waterproof and moisture-permeable property is based on the fact that the pore size of the film is smaller than the size of a raindrop but larger than the size of a water vapor molecule, so that water droplets cannot pass through to prevent water from leaking, and water vapor molecules can pass through to allow moisture to permeate.

[0028] In some embodiments, the strength layer 1 is woven from high modulus yarns 12 twisted from polyester fibers and aramid fibers. The high modulus yarns 12 have a fineness of 1500D and a breaking strength of 308.7N.

[0029] In some embodiments, the warp yarns of the strength layer 1 are in floating position, and the weft yarns of the strength layer 1 are in sinking position. The weave cycle of the strength layer 1 is: sink-float-sink-float-sink-float, float-float-float-sink-sink-sink, sink-float-sink-float-sink-float, float-sink-float-sink-float-sink, float-float-float-sink-sink-sink, and float-sink-float-sink-float-sink. Fig. 3 As can be seen, the third and fourth warp yarns and the sixth and first warp yarns are interwoven with weft yarns in plain weave, and the warp and weft yarns are opposite to each other, so that the third and fourth warp yarns and the sixth and first warp yarns are not easy to move close to each other. In addition, under the action of the second and fifth weft yarns, the first, second, and third warp yarns move close to each other, and the fourth, fifth, and sixth warp yarns also move close to each other, so that longitudinal gaps are formed between the third and fourth warp yarns and between the sixth and first warp yarns. Similarly, transverse gaps are formed between the third and fourth weft yarns and between the sixth and first weft yarns, and finally the longitudinal gaps and the transverse gaps are superimposed to form the through hole 11.

[0030] Obviously, the above embodiments of the present application are merely exemplary and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or modifications can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
