Problems solved by technology

This method reduces the application of strong alkali to a certain extent. The blasting will tear the physical tissue of the hemp skin and physically tear the tight structure of the hemp skin, which is also convenient for the invasion of microorganisms and water. For physical blasting, the fibers are easily torn, resulting in thick an

Embodiment 1

[0042] Embodiment 1: Apocynum bark degumming.

[0043] Alkali leaching: take the apocynum bark and prepare a potassium hydroxide soaking solution with a weight ratio of 2 to 4%. Soak in potassium hydroxide soaking solution for 40 to 90 minutes.

[0044] Alkali cooking: Treat for 40-90 minutes at a temperature of 103-108°C and a pressure of 0.15-0.3 MPa.

[0045] Fermentation: add water according to the weight of 8 to 10 times the weight of the apocynum husk, and then insert the degummed strains to ferment for 2 to 4 days.

[0046] The degumming strain is any one or a combination of several of Bacillus subtilis, Bacillus cereus and yeast.

[0047] Rinsing and dehydration: The fermented hemp fiber is crushed on a flax machine or rinsed with water on a flax machine to obtain fiber.

Embodiment 2

[0048] Embodiment 2: Degumming strain enrichment acclimatization.

[0049] Masterbatch preparation: crush the apocynum husk to remove fibers to obtain fiber-free apocynum husk powder.

[0050] Basic medium preparation: add 15 to 30 parts by weight of apocynum bark powder to 100 parts by weight of potassium hydroxide soaking solution with a concentration of 2 to 4% by weight, and cook at 0.15 to 0.25 MPa and 103 to 105°C for 20 to 60 Minutes, add water by 2 to 4 times the weight to obtain the basic acclimatization medium.

[0051] Preferably, the above-mentioned basal medium is prepared through the following process: every 2-4 parts by weight of potassium hydroxide is dissolved in 25-35 parts by weight of water, and 15-30 parts by weight of defibrated apocynum husk powder is added, under a pressure of 0.15-0.25 MPa 1. Cook at 103-105° C. for 30-60 minutes, and then add water so that the total amount of water reaches 100 parts by weight.

[0052] Any one or a combination of se...

Embodiment 3

[0055] Embodiment 3: Degumming strain enrichment acclimatization.

[0056] The difference from Example 2 is that the original species of the biological bacteria is taken from the Apocynum plantation field that has been planted for more than 3 years, and at least once in two or more different locations, and the obtained Apocynum plantation field soil mix.

[0057] Add 1 to 30 parts by weight of the soil obtained from the planting place of Apocynum apocynum in 100 parts by weight of the basal medium, preferably 5 to 10 parts by weight, and put it on a water bath shaking table at 35 to 39° C., 150 to 300r / min (220r / min) to carry out the bacteria Species enrichment and acclimatization culture for 2 to 5 days, and the liquid phase is taken after precipitation to obtain a once-enriched and acclimatized strain solution.

[0058] Repeat the secondary enrichment and domestication process for 3 to 5 times to obtain the target strain liquid as the degummed strain.

[0059] The original...

Abstract

The invention relates to an apocynum venetum peel degumming method. The method is mainly realized through the following technical processes of performing alkali soaking: soaking apocynum venetum peel in a potassium hydroxide soaking solution for 40-90 minutes; performing alkali boiling: performing boiling at the temperature of 103-108 DEG C under the pressure of 0.15-0.3 MPa for 40-90 minutes; and performing fermentation: inoculating a degumming strain and performing fermentation for 2-4 days. Apocynum venetum is beaten by a beating machine or rolled by a softening machine, washed with water and dehydrated to obtain fibers. Compared with the prior art, the method has the advantages that the alkali consumption is low, the energy consumption is low, high-concentration organic polluted wastewater is changed into special apocynum venetum organic biological trace element potash fertilizer which can be used for irrigating the apocynum venetum field, no wastewater is generated basically, organic matter, beneficial soil microbial florae, trace elements, potash fertilizer and the like are added for the apocynum venetum field, and the degumming wastewater difficult to treat is changed into sustainably used organic biological fertilizer which can be cyclically utilized for a long term.

Description

technical field [0001] The invention relates to a method for degumming apocynum bark, in particular to a method for degumming apocynum bark. Background technique [0002] Apocynum is a herbaceous perennial plant, and the leaves of Apocynum have the effects of clearing heat, calming liver, diuresis and detumescence. Indications for hypertension, dizziness, headache, palpitation, insomnia, edema and oliguria. [0003] Not only that, as a bast fiber plant, apocynum fiber has high fiber content and high fiber strength, so it has great utilization value. [0004] Apocynum fiber has the luster of silk, the crispness of hemp, the ductility of velvet, and the softness of cotton. It has the advantages of antibacterial, deodorizing, and mildew-proof. It can be purely spun or blended with cotton and other fibers to be spun into high-quality shirts, underwear and home accessories. [0005] But the utilization of apocynum fiber at first must remove non-cellulose components in the bast...
