Production method of insect-proof net for cultivation of navel oranges in Huanglongbing epidemic area

The invention relates to the technical field of cultivation of navel oranges in a Huanglongbing prevailing area, in particular to a production method of an insect-proof net for cultivation of navel oranges in the Huanglongbing prevailing area, which comprises the following steps: S1, preparing polyethylene fibers: the polyethylene fibers are ultra-high molecular weight polyethylene filaments, the fineness specification is 20-30D, the breaking strength is 3.0-4.0 N/tex, the tensile modulus is 91-140N/tex, and the elongation at break is 3.5-3.7%; s2, warping is carried out; s3, knitting: warp knitting parameters are as follows: the filament fiber parameter specification is 100d/1f, and the warp knitting mesh size is 0.2-2 square millimeters; and S4, setting: setting by using a hot air type tentering setting machine at the setting temperature of 130-150 DEG C for 60-90 seconds. The invention has the advantages that the ultra-high molecular weight polyethylene fiber has the characteristic of high strength, so tha
