摘要： The preparation in textile form of a cellulose N,Ndimethylorthoformamoylphosphorochloridite ester possessing flame and wrinkle resistance is described. The preparation is accomplished by preswelling the cellulose for 1 to 60 minutes in N,N-dimethylformamide, followed by reaction of the cellulose with 1-30% concentrations of phosphorus trichloride-N,Ndimethylformamide adduct in excess N,N-dimethylformamide as solvent, with or without an inert diluent, at 20-60* C for 1 to 180 minutes. After the reaction has been carried out to the desired extent of completion the modified cellulose is washed with an inert solvent. The modified cellulose contains nitrogen, phosphorus, and chlorine in a ratio of 1:1:1. If desired, the product can be freed of chlorine by subsequent washing in ice water, or may be used directly as an intermediate for further modification.

摘要： THE PREPARATION OF CELLULOSIC YARNS AND FABRICS HAVING 0.6-11% OF THE CELLULOSIC HYDROXYL GROUPS REPLACED BY CHLORINE ATOMS, AND A FURTHER 0.3-9% OF THE HYDROXYL GROUPS REPLACED BY CARBOXYALKYLTHIO OR CARBOXYARYLTHIO GROUPS, IN ADDITION TO APPRECIABLE CELLULOSE CROSSLINKING, LEADS TO TEXTILES OF INCREASED WRINKLE RECOVERY IN THE WET STATE, INCREASED AFFINITY FOR MOISTURE AND METAL IONS, ENHANCED AFFINITY FOR BASIC DYES, AND INCREASED RESISTANCE TO CELLULOSE SOLVENTS. THE CELLULOSIC TEXTILE IS FIRST CONVERTED TO CHLORODEXYCELLOSE IN TEXTILE FROM BY REACTION WITH THIONYL CHLORIDE IN DIMETHYLFORMAMIDE AT 20-30* C., AND IS SUPSEQUENTLY REACTED WITH MERCAPTO-SUBSTITUTED CARBOXYLIC ACIDS AT TEMPERATURES OF 50-110*C., IN THE PRESENCE OF SUFFICENT ALKALI METAL HYDROXIDE TO CONVERT BOTH THE MERCAPTO- AND CARBOXYLIC ACID GROUPS TO THEIR ANIOMIC FORMS, IN A SOLVENT CONSISTING OF MIXTURES OF STRAIGHT CHAIN ALIPHATIC ALCOHOLS WITH WATER, TO REPLACE SOME OF THE CHLORINE ATOMS BY CARBOXYALKYLTHIO- OR CARBOXYARYLTHIO-GROUPS.

摘要： THE PREPARATION OF CELLULOSIC YARNS AND FABRICS HAVING 0.67%-11% OF THE CELLULOSIC HYDROXYL GROUPS REPLACED BY CHLORINE ATOMS, AND A FURTHER 0.33%-7% OF THE HYDROXYL GROUPS REPLACED BY (AMINOALKYL) AMINO GROUPS, IN ADDITION TO APPRECIABLE CELLULOSE CROSSLINKING, LEADS TO TEXTILES OF INCREASED WRINKLE RESISTANCE IN THE WET STATE, ENHANCED AFFINITY FOR ACID DYES, AND INCREASED RESISTANCE TO CELLULOSE SOLVENTS. THE CELLULOSIC TEXTILE IS FIRST CONVERTED TO CHLORODEOXYCELLULOSE IN TEXTILE FORM, BY REACTION WITH THIONYL CHLORIDE IN DIMETHYLFORMAMIDE AT 20*-30* C., AND IS SUBSEQUENTLY TREATED WITH AN ALIPHATIC POLYAMINE DISSOLVED IN A STRAIGHT-CHAIN ALCOHOL OF 3-6 CARBON ATOMS AT 90*-130*C., TO REPLACE SOME OF THE CHLORINE ATOMS BY (AMINOALKYL)AMINO GROUPS.
