Embodiment
[0042] The basic steps of the production process of the special plant fiber nonwoven filter cloth for wet air puncture type drainage reinforcement in this embodiment are as follows:
[0043] The first step, the plant fiber raw material is first cut into short fibers, then opened into single fibers, and then the plant fibers are made into a suspension slurry, which contains plant-derived adhesives (no chemical adhesives are used here, which can avoid polluted environment);
[0044] The second step is to put the plant fiber suspension slurry into the wet-laid equipment to make a plant fiber web, or put the plant fiber suspension slurry and the plant fiber yarn net into the wet-laid equipment at the same time to make a web with yarn Vegetable webs of nets;
[0045] The third step is to puncture the plant fiber net with jet air, so that the fibers in the plant fiber net are entangled with adjacent fibers or yarns, and form a mechanical combination, and finally the plant fiber net...
