Abstract

The invention relates to liquid removing equipment and a liquid removing method. The liquid removing equipment comprises a liquid absorption roller which is used for contacting with an optical film material and absorbing the liquid on the surface of the optical film material. The liquid absorption roller comprises a core body and a water absorption material. The core body comprises a solid body portion and a hollow portion, the solid body portion comprises a plurality of through holes, and the water absorption material wraps the core body and covers the through holes.

Description

technical field [0001] The present invention relates to a liquid removal device and a liquid removal method, and in particular to a liquid removal device and a liquid removal method for an optical film material. Background technique [0002] In the preparation process of optical film, it is often necessary to soak it in various process baths for dyeing and crosslinking preparation process, surface treatment preparation process or water washing process, and then wind up after drying. However, before the drying of the optical film, the liquid remaining on the surface of the optical film cannot be effectively removed. After drying, these liquids are prone to water stains and / or dirt defects, which will affect the optical properties of the optical film. nature. Contents of the invention [0003] The object of the present invention is to provide a liquid removal device and a liquid removal method to solve the defect in the prior art that liquid remains on the surface of the op...
