Abstract:

Two mill runs N-9 and N-10 trials and the associated laboratory research work are described under the general program for making an improved type of Navy H-60 filter paper. The N-9 trial is concerned essentially with the optimum physical and chemical conditions for causticizing the viscose furnish, a great part of this laboratory study being concerned with the type and degree of washing that may produce a satisfactory product. It is demonstrated that a hydropulper, a piece of equipment commonly found in paper mills to defiber paper stock, will materially aid in the causticization procedure. Operating conditions such as temperature, caustic concentration, and degree of agitation are extremely important when causticizing stock in this equipment. The N-10 trial is concerned essentially with a study of the effect of blending causticized rope fibers with causticized rayon. Upon substituting 50 of the rayon with the causticized rope, there resulted a paper with markedly improved handling properties and with only a small decrease in efficiency. Author
