以二羟甲基丙酸(DMPA)和N-甲基二乙醇胺(MDEA)为扩链剂,通过封闭异氰酸酯端基(-NC0),合成了反应型水性聚氨酯固色剂.优化的合成工艺为:R值(-NCO与-OH物质的量之比值)为2.2,聚醚多元醇为PEG1000和PPG1000,比例为1:1,MDEA用量为预聚体质量的7.5%,DMPA用量为预聚体质量的3.40%,中和度为90%,端封-NCO预留量为30%;优化的固色工艺为:二浸二轧(整理剂80 g/L,轧余率75%)→预烘(47℃×3 min)→焙烘(150℃×3 min).试验结果表明,反应型水性聚氨酯固色剂应用于活性染料染色棉织物,可显著提高织物的色牢度.
以二羥甲基丙痠(DMPA)和N-甲基二乙醇胺(MDEA)為擴鏈劑,通過封閉異氰痠酯耑基(-NC0),閤成瞭反應型水性聚氨酯固色劑.優化的閤成工藝為:R值(-NCO與-OH物質的量之比值)為2.2,聚醚多元醇為PEG1000和PPG1000,比例為1:1,MDEA用量為預聚體質量的7.5%,DMPA用量為預聚體質量的3.40%,中和度為90%,耑封-NCO預留量為30%;優化的固色工藝為:二浸二軋(整理劑80 g/L,軋餘率75%)→預烘(47℃×3 min)→焙烘(150℃×3 min).試驗結果錶明,反應型水性聚氨酯固色劑應用于活性染料染色棉織物,可顯著提高織物的色牢度.

Taking 2,2-dimethylol propionic acid (DMPA) and N-methyldiethanolamine (MDEA) as chain extenders, reactive wa-ter-borne polyurethane fixing agent was synthesized by terminating isocyanate (-NCO) group. Optimum synthesis process was R value 2.2, PEG1000 to PPG1000 = 1 : 1, MDEA 7.5%, DMPA 3.4%, neutralization degree 90%, end terminated -NCO group 30%. Optimum fixing process was double-dip-double-nip with fixing agent 80 g/L and pick-up 75%, drying at 47 ℃ for 3 minutes,and curing at 150 ℃ for 3 minutes. Finished cotton reactive dyeings had obvious improvement in color fastness.
