Abstract:
In order to shorten the degumming cycle of flax fiber, reduce its production cost and improve its spinnability, the degumming process of oil-flax fiber was optimized, and the radio frequency heat treatment was applied to the degumming process. Surface morphology, whiteness, linear density and tensile properties of oil-flax fibers were characterized using field emission scanning electron microscopy, whiteness tester and electronic single fiber strength tester. The results show that the optimum biological degumming process are as followed. The treatment temperature is 45 ℃, the pH value is 4.5, the bath ratio is 1:15, the treatment time is 25 h and the enzyme dosage is 3 mL. Radio frequency(RF) treatment significantly improves the dispensability and morphology of oil-flax fiber. In addition, the fineness and linear density of the oil-flax fiber are significantly reduced with prologation of the RF treatment time. The overlong processing time reduces the crystallinity and affects the tensile properties of the fiber, so the best RF treatment time is10~30 min.
Key words: oil-flax fiber, radio frequency treatment, biological degumming, residual ratio, mechanical property
