[0036] like Figure 2~3 Shown: the main body 6 of the breathable bag is sewn from the grass-proof cloth 1, and the grass-proof cloth 1 is woven from the warp yarn 4 and the weft yarn 3 at one time. In this embodiment, the ventilation part 2 is only woven by warp yarns 4, and the grass-proof cloth 1 on both sides of each ventilation part 2 is provided with twisted threads 5, so as to prevent the warp yarns 4 on both sides of the ventilation part 2 from shifting , to ensure the regularity and overall aesthetics of the weaving anti-grass cloth 1, and the twisted yarns 5 and the warp yarns 4 are arranged in parallel. In this embodiment, the twisted wire 5 is a fishing net wire. The tensile strength of the warp yarn 4 and the weft yarn 3 is greater than or equal to 5.5g/D, so as to ensure the overall tensile strength of the grass-proof cloth 1 woven subsequently.
[0037] The edge of the grass-proof cloth 1 is woven with a drawing wire 7 , and when the air-permeable bag body 6 is sewn from the grass-proof cloth 1 , the drawing wire 7 is located at the upper opening of the breathable bag body 6 .
[0038] A method of making the above-mentioned breathable bag, comprising the steps:
[0039] (a) plasticizing and extruding the plastic through an extruder to form a film, and cutting the film into individual flat filaments;
[0040] The raw material is plasticized and extruded through an extruder to form a plastic film, and then the plastic film is cut into single flat filaments. The width of the flat filaments is set as required. Guarantee the overall tensile strength of the subsequently woven grass-proof cloth 1 .
[0041] (b) Weaving the grass-proof cloth 1 with the flat yarns as the weft yarns 3 and the warp yarns 4, and evenly withdrawing the weft yarns 3 or the warp yarns 4 at regular intervals, and adding a twisted wire 5 to the edge of the weft yarns 3 or the warp yarns 4 removed;
[0042] Use the flat yarns as weft yarns 3 and warp yarns 4 to weave the grass-proof cloth 1, place the weft yarns 3 and the warp yarns 4 on the loom to weave, and evenly draw off some of the warp yarns 4 at regular intervals to form the air-permeable part 2. The distance is the distance between adjacent air-permeable parts 2 , and the width of the drawn warp yarn 4 is the width of the air-permeable part 2 . Add a twisted yarn 5 on the edge of the drawn warp 4. The diameter of the twisted yarn 5 is smaller than the width of the warp yarn 4, so that it can play the role of twisting, avoid the warp 4 on the edge of the ventilation part 2 from shifting, and ensure the anti-woven fabric. The regularity and overall aesthetics of the grass cloth 1. In this embodiment, the twisted wire 5 is a fishing net wire. The width of the ventilation part 2 and the distance between adjacent ventilation parts 2 can be adjusted as required.
[0043] (c) Braided wire drawing 7 on one side of the grass-proof cloth 1;
[0044] A drawing wire 7 is woven on one side of the grass-proof cloth 1 , the length of the drawing wire 7 is longer than that of the grass-proof cloth 1 , and the drawing wire 7 is slidably arranged on the grass-proof cloth 1 .
[0045] (d) Cut the grass-proof cloth 1 and sew it into the breathable bag body 6 , and install the handle 8 on the upper side of the breathable bag body 6 .
[0046] The grass-proof cloth 1 is cut according to the size of the air-permeable bag body 6 , and then the cut grass-proof cloth 1 is sewn into the breathable bag body 6 . The drawing wire 7 is always located on the upper side of the air-permeable bag main body 6 during cutting and sewing, so that the air-permeable bag main body 6 can be easily closed by drawing the wire. A handle 8 is installed on the upper side of the air-permeable bag body 6 so as to facilitate the taking of the air-permeable bag body 6 .
[0047] Coloring the main body 1 of the breathable bag according to the different items to be contained can not only facilitate the selection of the breathable bag for the items during use, but also play a certain role in protecting the vegetables or fruits contained. For example, the breathable bag containing potatoes can be painted black to reduce the probability of potatoes sprouting.

Example Embodiment
