Embodiment 1
[0024] Present embodiment provides a kind of processing technique of bamboo fiber for seedling raising base cloth, and its technological process is as follows:
[0025](1) Mechanical pretreatment: the bamboo is repeatedly rolled by rollers for 120 times to obtain a rough material, and then washed with water to initially remove part of the hemicellulose and lignin attached to the surface of the fiber;
[0026] (2) Pre-soaking treatment: Soak the crude material obtained in step (1) in a peracetic acid pre-soaking treatment solution, wherein the concentration of peracetic acid is 4%, the temperature is 65° C., the pH value is 6, and the time is 65 minutes; After completing the pre-soaking process, rinse with water again to obtain bamboo fiber;
[0027] (3) Scouring: the bamboo fiber obtained in step (2) is further scoured, rinsed with 80°C hot water after scalding, and then washed with 20°C cold water; wherein, the bath ratio of scoured is 1: 9. The scouring temperature is 60°C,...
Embodiment 2
[0033] Present embodiment provides a kind of processing technique of bamboo fiber for seedling raising base cloth, and its technological process is as follows:
[0034] (1) Mechanical pretreatment: the bamboo is repeatedly rolled by rollers for 150 times to obtain a rough material, and then washed with water to initially remove part of the hemicellulose and lignin attached to the fiber surface;
[0035] (2) Pre-soaking treatment: Soak the crude material obtained in step (1) in a peracetic acid pre-soaking solution, wherein the concentration of peracetic acid is 4%, the temperature is 70° C., the pH value is 7, and the time is 80 minutes; After completing the pre-soaking process, rinse with water again to obtain bamboo fiber;
[0036] (3) Scouring: the bamboo fiber obtained in step (2) is further scoured, rinsed with 90°C hot water after scalding, and then washed with 30°C cold water; wherein, the bath ratio of scoured is 1: 12. The scouring temperature is 70°C, the scouring t...
Embodiment 3
[0043] Present embodiment provides a kind of processing technique of bamboo fiber for seedling raising base cloth, and its technological process is as follows:
[0044] (1) Mechanical pretreatment: The bamboo is repeatedly rolled by rollers for 180 times to obtain a rough material, and then washed with water to initially remove part of the hemicellulose and lignin attached to the surface of the fiber;
[0045] (2) Pre-soaking treatment: Soak the crude material obtained in step (1) in a peracetic acid pre-soaking solution, wherein the concentration of peracetic acid is 5%, the temperature is 75° C., the pH value is 8, and the time is 90 minutes; After completing the pre-soaking process, rinse with water again to obtain bamboo fiber;
[0046] (3) Scouring: the bamboo fiber obtained in step (2) is further scoured, rinsed with 80-100°C hot water after the scoured, and then washed with 35°C cold water; wherein, the bath ratio of scoured is 1:14, the scouring temperature is 80°C, t...
