摘要
从银杏叶提取内生菌进行培养,分离内生菌所分泌的红色素,将红色素用于经端氨基超支化合物季胺盐HBP-QAC接枝改性的真丝织物进行染色工艺研究。以染色织物的K/S值和相关的色牢度为考核指标,进行银杏叶内生菌分泌的红色素对HBP-QAC改性真丝织物染色工艺条件的单因素优化实验,得到的较佳染色工艺条件为：温度70℃,pH为3,元明粉用量为15g/L,时间为60min。在该较优条件下所染织物的皂洗牢度达到5级,摩擦色牢度达4-5级,耐日晒色牢度3级。HBP-QAC改性后的真丝织物的表面正电荷增加,使得织物与染料之间的离子键作用力增强,故而使其染色真丝织物的K/S值和染色牢度提高。
This study extracts endophyte from ginkgo leaf for cultivation, separates red pigment secreted by endophyte and uses red pigment for real silk fabrics subject to graft modification with amino-terminated hyperbranched polymer quaternary ammonium salt HBP- QAC for the study on dyeing process. Optimal conditions for dyeing process are obtained through single-factor optimal experiment on dyeing process conditions of real silk fabrics modified with HBP-QAC with red pigment secreted by ginkgo biloba endogenous by using K/S value of dyed fabric and relevant color fastness as assessment indicators： temperature 70℃, pH 3, dosage of anhydrous sodium sulphate 15g/L and time 60min. Fabrics dyed under such optimal conditions have washing fastness at grade 5, rubbing fastness at grade 4-5 and color fastness to sunlight at grade 3. Positive surface charge of real silk fabrics after modification with HBP-QAC increases, thus reinforcing the acting force of ionic bond between fabric and dye and improving K/S value and color fastness of dyed silk fabrics.
