| 摘要:本研究将甲醇蛋白与棉纤维素分别进行物理共混和化学交联共混,基于四丁基氢氧化铵(TBAH)/二甲基亚砜(DMSO)/水溶剂体系,再通过湿法纺丝制备甲醇蛋白改性纤维素纤维(SCP-RCF)。通过傅里叶变换红外光谱仪(FT-IR)、X射线衍射仪(XRD)、单纤维强力仪及凯氏定氮仪等对SCP-RCF进行了结构表征与性能测试。结果表明,物理共混制得的SCP-RCF力学性能较差且水洗后蛋白保有率较低;固定甲醇蛋白添加量为10%,对其进行化学交联实验,发现加入1,4-丁二醇二缩水甘油醚(BDDE)后可显著提高其综合性能;当BDDE添加量为5%时,制得SCP-RCF断裂强度由 1.5 cN/dtex提升至1.78 cN/dtex,断裂伸长率由6.4%提升至12.5%,且水洗后蛋白质保有率从24.9%提高至65.1%。 |
| Abstract:This study prepared methanol-protein modified cellulose fibers (SCP-RCF) by wet spinning after subjecting methanol protein and cotton cellulose to physical blending dissolution and chemical crosslinking blending dissolution in TBAH/DMSO/H2O solvent system, respectively. Structural characterization and performance testing of SCP-RCF were conducted using Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), single-fiber strength tester, and Kjeldahl nitrogen analyzer. The result showed that physical blended SCP-RCF exhibited poor mechanical properties and low protein retention after washing. At a fixed methanol protein addition amount of 10%, chemical crosslinking experiments revealed that adding 1,4-butanediol diglycidyl ether (BDDE) significantly enhanced overall performance. At a BDDE addition amount of 5%, the breaking strength of prepared SCP-RCF increased from 1.5 cN/dtex to 1.78 cN/dtex, the elongation at break rose from 6.4% to 12.5%, and the protein retention rate after washing improved from 24.9% to 65.1%. |
