Embodiment 1
[0021] Mix 1 kg of ramie raw hemp with 4 kg of acetone, and reflux and scorch at 60°C for 5 hours to obtain de-lignified hemp fibers. Immerse this treated fiber in 10 kilograms of organic degumming liquid, rise to 60 ℃ from room temperature with half an hour, handle 2 hours, take out washing, oiling, drying to obtain 650 grams of 1650 ramie fibers for textile use. Each kilogram of organic degumming liquid contains 250 grams of hydrogen peroxide, 10 grams of sodium polyacrylate, 50 grams of urea, 40 grams of carboxymethyl cellulose, and the rest is water.
Embodiment 2
[0023] Mix 1 kg of raw flax with 2 kg of methyl ethyl ketone, and scour at 120°C for 2 hours to obtain de-lignified hemp fiber. Immerse this treated fiber in 20 kg of organic degumming solution, rise from room temperature to 100°C with half an hour, process for 1 hour, take out washing, oiling, drying to obtain 720 grams of 1100 flax fibers for textile use. Each kilogram of organic degumming solution contains 100 grams of hydrogen peroxide, 100 grams of citric acid, 80 grams of urea, 10 grams of carboxymethyl cellulose, and the rest is water. Jute or kenaf.
Embodiment 3
[0025] Mix 1 kg of jute raw hemp with 3 kg of butyl acetate, and scour at 120°C for 3 hours to obtain de-lignified hemp fiber. Immerse this treated fiber in 15 kg of organic degumming solution, rise to 50 ℃ from room temperature with half an hour, handle 4 hours, take out washing, oiling, drying to obtain 790 grams of jute fiber for weaving with 750 branches. Each kilogram of organic degumming solution contains 200 grams of hydrogen peroxide, 40 grams of disodium edetate, 10 grams of urea, 70 grams of carboxymethyl cellulose, and the rest is water.
