Example Embodiment
[0030] Example 1
[0031] The preparation method of ramie fiber for high-count textile fabric of this embodiment includes the following steps:
[0032] 1) Pre-soaking: According to the ratio of bath ratio of 1:3.0, ramie raw hemp is immersed in a prepreg solution with a sodium hydroxide concentration of 20.0g / L for 20 minutes, and then taken out and dried until the water content is 50%. , Get prepreg;
[0033] 2) Steam explosion: Place the prepreg obtained in step 1) in a steam explosion device for steam explosion, the steam temperature is 200°C, the explosion pressure is 3.2MPa, the insulation and pressure retention is 4.0min, and the pressure is released to obtain steam explosion material;
[0034] 3) Scouring: According to the liquor ratio of 1:10, the steam explosion material discharged from the steam explosion device in step 2) is directly loaded (interval time ≤ 2min) into the scouring device containing degumming liquid for scouring. Heat preservation and scouring at 95°C for 3...
