In manufacturing a synthetic fiber, such as nylon paper, the following differences in papermaking properties are observed between paper of cellulosic fibers and synthetic fibers.(1) Because of the hydrophobic nature of nylon fiber, it is difficult to disperse it properly in water.(2) Nylon fiber has no fibril structure.(3) Nylon fibers do not bond on drying or with pressure alone, unlike hydrated and fibrillated cellulose.It is possible that synthetic fiber papers, in general, may have the application to the non-woven fibric and the usual type of paper for printing.This experiment was carried out to manufacturing the latter type of synthetic fiber paper. To overcome the lack of printability of nylon synthetic fiber paper, Mitsumata cellulosic fiber was blended into nylon stock with the ratio of 1 : 1.In this paper a summary of the results of examination concerned with commercial production of the nylon blended Mitsumata paper is presented.The following results were obtained in consequence of the experiments : 1. Polyacrylate was found to be effective to yield better fiber dispersion and better sheet formation in the fourdrinier machine process.2. Bonding agent was added to the water leaves of nylon blended Mitsumata by dipping them in the emulsion or methanol solution of bonding agents.3. Two types of nylon derivatives were used as the bonding agent of nylon blended Mitsumata sheet.N-methoxymethyl nylon 6 proved most effective to improve the wearing quality, strength properties and resistibility to chemicals of sheets.4. The sheet properties were remarkably improved in folding endurance, wearing quality and resistibility to chemicals.5. Amount of ink transfer from form to the nylon blended Mitsumata paper, in general, was less than to the Mitsumata paper.6. The nylon blended Mitsumata paper had a weaker tendency to cause the troubles of strike through and show through of the print.
