Process for treating non-kerations material with a polythiol resin and an aminoplast and the product obtained

摘要

The present invention relates to a process for improving the mechanical properties of cellulosic fibres. The effects are achieved by impregnating the fibres, especially those treated with an aminoplast, with a resin containing at least two mercaptan groups linked through poly(oxyalkylene) chains to a radical of a polyhydric alcohol.
