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.

Abstract

The invention discloses a mulberry bark degumming method. The method comprises the following steps: removing surface layer spots and scabs from new sheared ramulus mori, peeling mulberry bark, and removing mulberry bark surface green peel; immersing the above obtained processed mulberry bark in water, striking, and washing by using clear water; carrying out steam explosion on the above obtained processed mulberry bark to obtain mulberry bark fibers, and washing the mulberry bark fibers by using clear water; carrying out microbial degumming on the washed mulberry bark fibers, washing fermented mulberry bark fibers by using clear water, and dehydrating; immersing the dehydrated mulberry bark fibers in an oil emulsion, taking out the immersed mulberry bark fibers, stacking, and oiling; and loosing the oiled mulberry bark fibers, drying the flattened mulberry bark fibers in an oven to obtain a finished degummed mulberry bark fiber product. The method adopts steam explosion physical effect to loosen gums and also adopts a biological technology to digest residual partial gums in order to realize cleaning and efficient degumming purposes and solve the technical problems of traditional mulberry bark degumming methods.

Description

technical field [0001] The invention belongs to the technical field of fiber production, and in particular relates to a method for degumming mulberry bark. Background technique [0002] Mulberry belongs to the genus Moraceae. my country is the earliest country in the world to plant mulberry and raise silkworms, and the collected and preserved mulberry germplasm belongs to 15 mulberry species and 3 varieties. It is the country with the most mulberry species in the world. Among them, the cultivated species include Lusang, white mulberry, Guangdong mulberry, Ruisui mulberry; wild mulberry species include long spike mulberry, long fruit mulberry, black mulberry, Hua mulberry, fine-toothed mulberry, Mengsang, mountain mulberry, Chuan mulberry, Tanggui mulberry , Dian mulberry, and chicken mulberry; variants include ghost mulberry (a variant of Meng mulberry), big leaf mulberry (a variant of white mulberry), and weeping mulberry (a variant of white mulberry). Mulberry is cultivat...
