Abstract
The invention discloses a hollow fiber film production method which comprises the following steps of: selecting a basic structure line, namely taking the hollow fiber film as the basic structure line, taking the basic structure line as a warp yarn or a weft yarn, and taking a polyester thread or a cotton thread as the warp yarn or the weft yarn for weaving. When the polyester thread or the cotton thread is woven on the basic structure line, the hollow fiber yarn is uniform in distribution, and the phenomena that the hollow fiber film has multiple separating dead angles, the film yarn is non-uniform in distribution and the glue water cannot enter the fiber film thus forming a hole and causing waste are avoided. Because the polyester thread or the cotton thread is woven on the basic structure line, the hollow film yarn is uniform in distribution in the weaving process, and the condition that the film yarns are stacked in a concentrated mode is greatly avoided. Therefore, the hollow fiber film manufacturing by the method has the advantages that the water distribution is uniform; the hollow fiber film is convenient to package, the packaging quality is high, and the glue water hole is avoided; and moreover, the film yarn distribution is full and the like.
