Preparation method of high-bonding intensity weaving pipe enhanced hollow fiber composite film

The invention discloses a preparation method of a high-bonding intensity weaving pipe enhanced hollow fiber composite film. The preparation method comprises the following steps of (1) rinsing treatment: dragging a weaving pipe to a rinsing groove to be cleaned, and performing hot air drying treatment; (2) soaking treatment: dragging the weaving pipe in the step (1) into an ultra-low concentration polymer solution A to be soaked, and then, performing hot air drying; (3) spinning forming: pouring the soaked weaving pipe in the step (2) into a spinning head; coating a polymer casting film liquid B; putting the weaving pipe into a coagulating bath; performing curing forming to obtain a weaving pipe enhanced film; (4) post treatment: rinsing the weaving pipe enhanced film in pure water for 12 to 24 h; finally, putting the weaving pipe enhanced film in protection liquid for 8 to 12h; drying the film in the air. The method has the advantages that through the rinsing on the weaving pipe and the soaking treatment by the ultra-low polymer solution, the weaving pipe is subjected to roughening treatment, meanwhile, the used polymers are homogeneous materials, the bonding intensity between the coating layer and the weaving pipe can be obviously improved; the reverse flushing resistance is higher; the operation process is simple; the industrialization can be easily realized.
