Nippon Synthetic Chemical Industry Co., Ltd. has developed a new form of binder, identified as a Gohsenol p-200, specifically designed for vinylon fibers.The effects of PVA powder as a bonding agent of vinylon paper have been mentioned in practice. The manufacture of vinylon paper on a pilot fourdrinier paper machine by using PVA powder as a bonding agent by the beater addition were studied.Physico-chemical properties of vinylon paper by using PVA powder is better than that of PVA fiber.PVA powder is convenient to handle and paper-making readily in the mill. For the most efficient results, care should be taken to select the preferred PVA powder for the specific need.

The results of a study of the properties of paper treated with PVA powder by the beater addition are presented.Factors affecting the retention and the strength of the sheets are discussed including the rate of dissolution, particle size of the resin in the range of saponification degree 95.7-99.9%. The absorption water of the sheets are needed more than 60% before drying process.Major advantage was found in the use of PVA powder as beater addition for paper strength.
