説明

In the design of effective shrink-proof modification of cellulosics, the factors to be considered include cost, efficiency, durability of shirink-proofing, and effect of the treatment on other fabric properties. A number of the finishings of rayon were performed with the use of crude phosphoryl amides prepared from the reaction of phosphoryl chloride with a saturated solution of ammonia in methanol (method A), from the reaction of ammonia with a solution of phosphoryl chloride (or chloro-phosphazene) in a solvent such as chlorinated alkanes or arenes, and ethers (method B).<BR>The most eminent characteristics in the use of the phosphoryl amides prepared by method A were the more efficient durable shrink-proofing and fastness against chlorine damage than the case of method B. The increase in the amounts of methoxy-substituted products at high reaction temperatures in metod A caused the decreases in efficiency of shrink-proofing and whiteness of the treated rayon.<BR>Presence of water in methanol afforded hydroxy-substituted products and ammonium phosphate derivatives . However, the crude phosphoryl amides prepared in the presence of a small amount of water gave more desirable shrink-proofing, probably due to the catalytic effect of ammonium phosphate formed for the shrink-proofing .The optimum amount of water in the methanol for shrink-proofing was about 10%. Sodium borohydride treatment before the shrink-proofing increased the whiteness of fabrics.
