ABSTRACT:
The invention relates to a high molecular absorbent sheet manufacturing process and the related equipment for employing such manufacturing process. The process includes a step of sending a paper pulp and a high molecular absorbent compound to a trough for mixing by wired cylinders and spreading over a conveyer system, a step of drying the mixture carried on the conveyer system, and a step of squeezing the dried mixture into a roll of high molecular absorbent sheet through two matched hot impression cylinders. A sheet of thermoplastic mesh fabric may be respectively covered on the mixture on two opposite sides before the process of drying.
