The reaction of cellulose with milk casein and epichlorohydrin was studied in order to prepare a viscose fiber grafted with milk casein. 15% of milk casein in an aqueous solution of 1% sodium hydroxide was reacted with 1_??_3% of epichlorohydrin to the weight of casein and then the product was added to viscose, which contained 15_??_20% of casein to the weight of cellulose.
The spinning was carried out by the usual viscose spinning method and a new type of chemical fiber conbining cellulose with milk casein was prepared.
This method of fiber-making is not that of merely spinning the mixture of cellulose and milk casein. Thus the properties of fiber obtained extensively varies in its properties depending on the amount of grafting agent (epichlorohydrin) used as well as on the relative amounts of the two polymers.
In addition to the usual properties of viscose fiber, this fiber grafted with milk casein has such good properties as the the affinity to dyestuff for wool, fastness to light, burning resistance, heatretaining property and resistance against wool-attacking insects, moulds and mildews.
