Embodiment 1
[0018] Harvested raw flax stems were processed with a roller compactor to break the epidermis, rinsed with water, and soaked in water for 9 hours at a water bath ratio of 1:20 (w / v). Put the pretreated raw flax stems in water, soak for 20 minutes, and drench for 1 minute to remove excess water. The measured water consumption is 33.4%. Insulate at 30°C for degumming. After 96 hours, the degumming was completed. Rinse with water repeatedly to remove the degumming solution, and heat and dry at 80°C to obtain flax fibers.
[0019] The control experiment carried out at the same time did not adopt the short-time dipping process, and the degumming completion time was 96 hours.
Embodiment 2
[0021] Harvested raw flax stems were washed with water and soaked in water for 10 hours at a water bath ratio of 1:20 (w / v). The pretreated raw flax stems were placed in 4 g / L alkaline pectinase enzyme preparation solution added with 0.2% ammonium oxalate, soaked for 10 minutes, and drenched for 30 seconds, and the consumption of enzyme solution was measured to be 26.7%. Insulated at 45°C for degumming. After 48 hours, the degumming was completed. Rinse repeatedly with water to remove the enzyme solution, heat and dry at 80°C to obtain flax fibers.
[0022] The control experiment carried out at the same time did not adopt the short-time dipping process, and the degumming completion time was 40 hours.
Embodiment 3
[0024] Harvested raw flax stems were washed with water and soaked in water for 10 hours at a water bath ratio of 1:20 (w / v). The pretreated flax raw stems were placed in water added with 2g / L urea, soaked for 30 minutes, and drenched for 30 seconds. The consumption of urea aqueous solution was measured to be 28.4%. Insulate at 35°C for degumming. After 100 hours, the degumming was completed. Rinse repeatedly with water to remove the degumming solution, and heat and dry at 100°C to obtain flax fibers.
[0025] The control experiment carried out at the same time did not adopt the short-time dipping process, and the degumming completion time was 96 hours.
