LINER PAPER WITH HIGH AIR PERMEABILITY, HIGH WET STRENGTH, ANTI-MILDEW AND ANTIBACTERIAL PROPERTIES FOR LIQUID CRYSTAL GLASS

In this paper, we report a method for the preparation of liner paper applied on liquid crystal glass. It was obtained by wet forming of hardwood fiber and a laboratory-made hydrophilic dispersible polyester staple fiber in a certain proportion. The laboratory-made hydrophilic dispersible polyester staple fiber was obtained by co-deposition of gallic acid and ethylenediamine on PET fiber. Some additives were used in the papermaking process, including wet strength agent polyamide epichlorohydrin (PAE), anti-mildew and antibacterial agent polyhexamethylene biguanide (PHMB), and pH adjuster boric acid (H3BO3). Results showed that the liner paper has high air permeability (~35.99 μm.(Pa∙s)-1), good wet strength (~0.720 kN.m-1) and excellent anti-mildew and antibacterial properties. Interestingly, the pore size of the modified PET fiber paper increased between 23% and 29% within the same pore size range compared with PET fiber paper. This provides a theoretical basis for the relationship between paper pore size and air permeability.
