Embodiment 1
[0027] 1. Scrub the newly cut mulberry branches with a clean steel ball to remove surface dandruff and scars, reduce impurities brought into the subsequent process, and peel off the mulberry bark.
[0028] 2. Use a scraper to scrape off the green skin on the surface of the mulberry bark. It is better if the mulberry bark is white or fiber appears, so as to avoid damage or loss of fiber.
[0029] 3. Take 100g of mulberry bark, put it into a 1L container, add 50g of water, and beat the mulberry bark with a wooden hammer at a frequency of 120 times / min for 15 minutes, then rinse the mulberry bark with clean water.
[0030] 4. The concentration of the mulberry bark in the previous step in 100ml is 5% NaHCO 3 Soak in the solution for 30 minutes, drain to make the moisture content of the mulberry bark 300%, pour it into a steam explosion tank, heat and pressurize, keep at a pressure of 1.6MPa for 10 minutes, quickly open the pressure relief valve, and steam explosion occurs. The mu...
Embodiment 2
[0035] 1. Scrub the newly cut mulberry branches with a clean steel ball to remove surface dandruff and scars, reduce impurities brought into the subsequent process, and peel off the mulberry bark.
[0036] 2. Use a scraper to scrape off the green skin on the surface of the mulberry bark. It is better if the mulberry bark is white or fiber appears, so as to avoid damage or loss of fiber.
[0037] 3. Take 100g of mulberry bark, put it into a 1L container, add 50g of water, and beat the mulberry bark with a wooden hammer at a frequency of 30 times / min for 30 minutes, then rinse the mulberry bark with clean water.
[0038] 4. Put the step mulberry in 100ml concentration of 2% NaHCO 3 Soak in the solution for 30 minutes, drain to make the moisture content of the mulberry bark 80%, pour it into a steam explosion tank, heat and pressurize it, keep it at a pressure of 1.2 MPa for 10 minutes, quickly open the pressure relief valve, and steam explosion occurs. The mulberry fiber bundle...
Embodiment 3
[0043] 1. Scrub the newly cut mulberry branches with a clean steel ball to remove surface dandruff and scars, reduce impurities brought into the subsequent process, and peel off the mulberry bark.
[0044] 2. Use a scraper to scrape off the green skin on the surface of the mulberry bark. It is better if the mulberry bark is white or fiber appears, so as to avoid damage or loss of fiber.
[0045] 3. Take 100g of mulberry bark, put it into a 1L container, add 50g of water, and beat the mulberry bark with a wooden hammer at a frequency of 240 times / min for 10 minutes, then rinse the mulberry bark with clean water.
[0046] 4. Put the mulberry bark of the previous step at a concentration of 6% NaHCO in 100ml 3 Soak in the solution for 30 minutes, drain to make the moisture content of the mulberry bark 50%, pour it into a steam explosion tank, heat and pressurize it, keep it at a pressure of 2 MPa for 5 minutes, open the pressure relief valve quickly, and steam explosion occurs.
