无醛固色剂HP的研制与应用

Preparation and application of formaldehyde-free fixing agent HP

开发了阳离子高聚物的无甲醛固色剂HP，探讨了二烯丙基胺用量、pH、催化剂及其用量、反应温度、反应时间、金属离子捕捉剂对终产物粘度的影响，确定了较优合成工艺：”（二烯丙基胺）=10％（对N，N-二甲基二烯丙基氯化铵质量），同时加入金属离子捕捉剂c，调节pH=6，慢速滴加（1．5h滴完）过硫酸铵和焦亚硫酸钠的氧化还原催化剂·过硫酸铵用量为0．8％（对反应物总质量），焦亚硫酸钠用量为0．5％（对反应物总质量）]，80℃反应3～4h，经过固色整理，发现其固色效果良好．另外，测试无甲醛固色剂HP对多种活性染料的固色效果，结果表明其性能较好．

Formaldehyde-free fixing agent HP based on cationic high polymer was prepared. The effects of di-2-propenylamine dosage, pH, catalyst and dosage, temperature of reaction, time, metallic ion capture agent on the viscosity of end product were investigated. The optimum synthesis process conditions were determined： w（di-2-propenylamine）=10%（on the weight of N,N-dimethyl-di-2-propenyl aminium chloride）, metallic ion cap- ture agent was introduced, and pH was 6, 0.8%（on the weight of total reactant） of ammonium persulfate and 0.5%（on the weight of total reactant） of sodium metabisulfite redox catalyst was slowly dropwised within 1.5 h, and reacted at 80℃ for 3-4 h. HP was applied in fixing finish and had good fixation effect. The fixing effects on sev- eral reactive dyes were also tested, and the experiment showed that it was a fixing agent with good performance.
