Method for manufacturing transfer paper

Abstract

A method of making transfer paper in which surfactant is applied either after the step of refining and before the paper sheet formed or on the surface of the paper sheet. The surfactant includes aqueous wax emulsion or fluorochemical. The present disclosure accomplishes papermaking by paper machine, with no need of coater.

What is claimed is: 
     
         1 . A method for manufacturing transfer paper, comprising steps of pulp preparation, dissolution, refining, filtering, blend, dilution, pump, forming paper sheet, press, pre-drying, surface sizing, and after-drying, wherein surfactant is added after refining and before the paper sheet is formed. 
     
     
         2 . The method according to  claim 1 , wherein the surfactant comprises aqueous wax emulsion or fluorochemical. 
     
     
         3 . The method according to  claim 2 , wherein the aqueous wax emulsion comprises paraffin wax emulsion. 
     
     
         4 . The method according to  claim 2 , wherein the aqueous wax emulsion comprises water-based polyethylene wax. 
     
     
         5 . The method according to  claim 2 , wherein the fluorochemical comprises C3 or C6 or C8 organic fluorine oil repellent 
     
     
         6 . The method according to  claim 2 , wherein the fluorochemical comprises fluorine silicide. 
     
     
         7 . The method according to  claim 1 , wherein the surfactant is applied in an amount of 1-30 kilogram per ton of paper. 
     
     
         8 . A method for manufacturing transfer paper, comprising steps of pulp preparation, dissolution, refining, filtering, blend, dilution, pump, forming paper sheet, press, pre-drying, surface sizing, and after-drying, wherein surfactant is applied at the step of surface sizing. 
     
     
         9 . The method according to  claim 8 , wherein the surfactant comprises aqueous wax emulsion or fluorochemical. 
     
     
         10 . The method according to  claim 9 , wherein the aqueous wax emulsion comprises paraffin wax emulsion 
     
     
         11 . The method according to  claim 9 , wherein the aqueous wax emulsion comprises water-based polyethylene wax. 
     
     
         12 . The method according to  claim 9 , wherein the fluorochemical comprises C3 or C6 or C8 organic fluorine oil repellent 
     
     
         13 . The method according to  claim 9 , wherein the fluorochemical comprises fluorine silicide. 
     
     
         14 . The method according to  claim 8 , wherein the surfactant is applied in an amount of 1-30 kilogram per ton of paper. 
     
     
         15 . The method according to  claim 8 , wherein the surfactant is applied individually to the surface of paper sheet. 
     
     
         16 . The method according to  claim 8 , wherein the surfactant is applied with a mixture of sizing agents to the surface of paper sheet. 
     
     
         17 . The method according to  claim 16 , wherein the weight ratio of surfactant to sizing agents is from 1:5 to 1:10. 
     
     
         18 . The method according to  claim 8 , wherein the surfactant is applied in a paper machine.
