摘要： 室温下,将再生纤维素与透明质酸(HA)、肝素(Hep)、丝素(SF)、甲壳素(N-ACS)等的复合纤维的纺丝液溶于NaOH溶液中,通过喷丝头(孔径0.1mm)喷入含有40%~43%硫酸铵的10%硫酸溶液中,得到产率为75%~98%的新型白色、柔韧性较好的复合生物纤维。FT-IR结果显示,复合纤维组分间存在物理吸附和氢键相互作用;少量的HA、Hep、SF和N-ACS等纤维的添加可增加复合纤维的韧能,其中纤维素-SF复合纤维在SF含量为10%时纤度为9.9旦,韧度值为1.08g/旦,伸长率为35.0%,机械性能相对最好。SEM图像中可以看出复合纤维表面呈现条纹、鳞状、填充和均匀包覆的结构,复合纤维间存在一定的相容性;复合纤维直径为19~55μm,密度为0.1~0.36旦/μm。

Abstract: Each spinning solution of cellulose was mixed with hyaluronic acid (HA), heparin (Hep), silk fibroin (SF) and chitin (N-ACS) in aqueous NaOH solution respectively at room temperature, They were sprayed into 10% sulfuric acid containing 40%-43% of ammonium sulfate through a spinneret (0.1 mm in hole diameter). Novel white blend biofilaments were obtained in 75%-98% yield. The flexibility of these biology fiber composites was also good. FT-IR spectra indicated that physical adsorption and hydrogen bond interaction existed between the components of composite fibers. A small amount of HA, Hep, SF, and N-ACS in composites would increase the flexibility of composite fibers. The cellulose-silk fibroin fiber has the best mechanical properties when the mass fraction of the silk fibroin was 10%. Its size was 9.9 denier, its tenacity value was 1.08 g/denier and its elongation value was 35%. The stripe, scaly, filling, and the evenly coated structure on the filaments surface were examined by SEM observation. It indicated that certain compatibility existed on the composite fibers. The diameter of composite fibers was 19-55 μm and the density was 0.1-0.36 denier/μm.

Key words: cellulose-hyaluronic acid fiber, cellulose-heparin fiber, cellulose-silk fibroin fiber, cellulose-silk fibroin-chitin fiber, cellulose-chitin fiber, biological composite fiber
