実験手順

An aqueous treating bath was prepared containing a given concentration of 1,2,3,4-butanetetracarboxylic acid and sodium dihydrogen phosphate in an agent to catalyst gfw ratio of 1:1.15. An all-cotton desized, scoured and bleached 80×80 printcloth weighing 3.2 oz/yd2 was thoroughly wetted by immersion in this treating bath, was passed between the rolls of a wringer, was again immersed in the treating bath, and was again passed through the wringer, the pressure of the wringer rolls being sufficient to give a wet pickup of 90-100% of aqueous mixture on the fabric, based on the original weight of fabric sample. The fabric was then dried in a forced draft oven at 85° C. for 5 minutes, and was heat-cured in a second forced draft oven at 180° C. for 90 seconds. The fabric was subsequently machine laundered and tumble dried. A sample finished with 5% DMDHEU and a 1.8% magnesium chloride hexahydrate-citric acid catalyst in a 20:1 gfw ratio was included as a control. The textile properties after one laundering cycle are given in Table XI
