本论文采用离子液体对未脱胶桑蚕丝进行脱胶,以单因素变量法对离子液体应用于桑蚕丝脱胶的工艺条件进行了研究。考察了离子液体的量、pH值、脱胶温度、浴比、脱胶时间等因素对脱胶性能的影响。研究表明当溶液pH=2、脱胶温度为98℃、时间为1h、浴比为1:50时,桑蚕丝的脱胶率约为23%,白度71左右;当溶液中加入体积含量2.0%的离子液体后,pH=2、脱胶温度为98℃、时间为1h、浴比为1:50时,脱胶率约为23%,白度达到80以上This paper described a method to degum the unscoured mulberry silk applying ionic liquid and researched the process condition applying ionic liquid in silk degumming using single-factor variable method, and also investigated the factors such as ionic liquid volume, pH value, degumming temperature, bath ratio, and degumming time that influenced the degumming performance. The study indicated that when the pH value of the solution was 2, degumming temperature was 98 ℃, the time was 1 hour, bath ratio was 1:50, the degumming rate of mulberry silk was about 23%, and the whiteness was about 71. When the solution added with ionic liquid of 2% of the solution volume, the pH value of the solution was 2, degumming temperature was 98 ℃, the time was 1 hour and bath ratio was 1:50, the degumming rate of mulberry silk came out to be about 23%, and the whiteness was greater than 80. 以上研究表明桑蚕丝在酸性条件下应用离子液体可提高脱胶性能,尤其是白度。以脱胶后的桑蚕丝进行染色研究表明,离子液体脱胶后的桑蚕丝上染率达到85%,色深值大于21。The study showed that the degumming performances, especially whiteness of mulberry silk, could be improved when applying ionic liquid in acid condition. The research of degummed mulberry silk after dyeing showed that the dye-uptake of ionic liquid degummed mulberry silk reached to 85%, and the dyeing depth was greater than 21. 注:1, 脱胶 degumming 2,色深:dyeing depth 3, 纯手工翻译,有帮助,请采纳.
