摘要
采用反相乳液聚合法，以N-乙烯基吡咯烷酮为提高增稠剂耐电解质能力的功能单体，N，N-亚甲基双丙烯酰胺为交联剂，丙烯酸为主要原料，合成了一种耐电解质增稠剂；考察了pH值、交联剂用量、溶剂种类及用量、乳化剂和耐电解质单体用量对增稠剂性能的影响；优化了合成工艺，并应用于活性染料印花。结果表明，该耐电解质增稠剂3％原糊黏度可达到11549mPa·s，抱水性为0．3era／15min，PVI值为0．26；应用于印花，织物得色量（正面K／S值）大于12，色泽不匀度小于0．104％，渗透率大于67％，脱糊率大于73％，干摩擦牢度为4-5级，湿摩擦牢度为3-4级。
（National Engineering Laboratory for Modern Silk, College of Textile and Clothing Engineering, Soochow University, Suzhou 215021, China） Abstract： Electrolyte-resistant thickener is prepared with inverse emulsion polymerization, using N-vinyl pyrrolidone as function- al monomer to improve the ability of electrolyte-resistance, using N, N＇-methylene bisacrylamide as crosslinker,acrylic acid as main monomer. The influence of pH, dosage of crosslinker, type and amount of solvent, dosage of emulsifier and electrolyte- resistant monomer on the main properties of thickener are discussed. 3-he synthesis process of electrolyte-resistant thickener is optimized. The thickener is used in reactive dye printing. The results show that the viscosity of the original paste containing 3 % self-made electrolyte-resistant thickener is 11 549 mPa ~ s, water retention is 0.3 cm/15 min, PVI value is 0.26. The color strength{ K/S） of the printed fabric is above 12, the degree of uneven dyeing is below 0. 104%, the penetration rate is above 6？%, the removal rate of paste is above 73%, the color fastness to dry rubbing is 4 -5 grade and wet rubbing is 3 -4 grade.
