Internally-bonded and externally-sprayed multi-layer three-dimensional woven bag
A technology of three-dimensional weaving and woven bags, applied in the field of woven bags, can solve the problem that the finished woven bags cannot have both anti-static, anti-oxidative strength and wear resistance, the finished woven bags cannot show a three-dimensional effect, and the coating cannot be significantly improved. Coating shrinkage problems and other problems, to achieve the effect of improving coating shrinkage problems, excellent weather resistance, and reducing edge cutting too wide

Embodiment 1
[0031] refer to Figure 1-3 As shown, a kind of multi-layer three-dimensional woven bag with internal adhesion and external spraying in this embodiment comprises a woven bag base layer woven from polypropylene plastic, and a styrene-methyl methacrylate film bonded to the inner layer of the woven bag base layer Layer, the ethylene-vinyl acetate copolymer film layer bonded in the styrene-methyl methacrylate film layer, the outer layer of the woven bag base layer is sprayed in turn to form an antistatic layer and a wear-resistant protective layer;
[0032]The preparation method of the inner-adhesive and outer-drenched multi-layer three-dimensional woven bag comprises the following steps:
[0033] S1. Preparation of plastic flat yarn: Extrude polypropylene granules into plastic strips through an extruder, and the plastic strips are cooled and sectioned, heated and stretched to prepare plastic flat yarns for use;
[0034] S2. Preparation of double-layer film layer: heat, melt and ...
