摘要
高支高密锦纶织物弱酸性染料印花时容易产生麻点,分析了产生麻点的原因;探讨了不同糊料和助剂对锦纶印花麻点轻重程度的影响,研究了表面活性剂对织物K/S值和最大吸收波长的影响,用分光光度法表征了助剂和染料的相互作用.结果表明:在色浆中加入阴离子A(双烷基双苯磺酸盐)0.1%、阳离子M(双烷基双季铵盐)0.075%和1815(聚合烷基季铵盐)0.05%的混合物,由于染料与阳离子、阴离子和非离子表面活性剂形成了稳定的相互作用,能基本去除麻点.
＂Spot＂constantly occurred during printing of high-count and high-density polyamide fabric by weak acid dye.In this paper,reasons for producing spot were analyzed.The influences of pastes and assistant on spot were investigated,and the effects of surfactants on K/S and λmax were discussed.The interactions between the dyes and surfactants were characterized by spectrophotometric method.The results indicated that the spot could nearly be removed by the addition of mixture of 0.1% Anionic A（dialkyl bi-benzene sulfonate）,0.075% Cat-ionic M（dialkyl bi-quaternary ammonium salt） and 0.05% 1815（poly-alkyl quaternary ammonium salt）.That was due to the stable interaction among dyes,cationic,anionic and nonionic surfactants.
