Open full text 0 citations

Abstract

In the previous paper1), we had seen that some physical properties of spun rayon fabric had been improved in which monomeric acrylic acid was polymerized in situ and then treated with Al-acetate solution to make them insoluble.The present paper discusses the optimum condition to insolubilise polyacrylic acid by Al-acetate and Ca-acetate, first with polymer coated fabric, and then confirmed by polymerizing in situ fabric.The following results were obtained:1. For insolubilisation of polyacrylic acid on the fabric, the following conditions are sufficient; treating temp. 30°C, time 1hr, conc. 0.1mol/1 by Ca (CH3COO)2, and 0.05mol/l by Al (CH3COO)3.2. The conditions of insolubilisation of polyacrylic acid on coated fabric and polymerized in situ fabric are similar in both cases.
