| 摘 要： | 针对红麻脱胶困难且传统脱胶方法污染严重的问题,提出一种新的脱胶方法,即闪爆-超声波联合脱胶。首先对红麻进行闪爆预处理,进而结合红麻超声波脱胶单因子试验和正交试验,以红麻精干麻纤维残胶率为考核指标,探讨了不同超声波频率、氢氧化钠介质浓度以及超声波处理时间对脱胶效果的影响。结果表明,在闪爆预处理后,采用频率为28 kHz的超声波在氢氧化钠浓度为2%的溶液中处理红麻试样60 min,可以使红麻精干麻纤维残胶率降低到9.72%,细度达到139.45 Nm。闪爆-超声波处理可有效去除红麻胶质成分,提高红麻精干麻的分散性,以利于后续纺织加工。

| Abstract: | Kenaf has a high content of gum that is difficult to remove. Traditional chemical degumming process causes serious environmental pollution. To solve the problem, we developed a new method to degum kenaf. We pretreated the kenaf with steam explosion followed by ultrasonic treatment. We chose the single factor tests to select the ultrasonic frequency, sodium hydroxide concentration and processing time. Combined with orthogonal tests, we found that the optimum conditions were as follows: ultrasonic frequency was 28 kHz, sodium hydroxide concentration was 2%, and processing time was 60 min. Under these conditions, the residual gum of kenaf fiber was 9.72% and the fineness was 139.45 Nm. Steam explosion combined with ultrasonic method is effective in degumming of kenaf. |
