| 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%. |
