Embodiment 1

[0064] Apocynum bast raw material origin: Xinjiang

[0065] The processing method is as follows:

[0066] Apocynum bast is placed in a closed tank, immersed in ethylenediamine with a mass percentage concentration of 40%, and continuously stirred at room temperature for 12 hours, so that the bast of apocynum is fully infiltrated and activated, and then the ethylenediamine in the tank is The diamine is vented, and the activated apocynum bast is taken out.

[0067] Then make a cake, place the degumming tank together with the gained apocynum bast and the hemp cage of the cake, and pump into the FeSO that the mass percent concentration is 0.05% 4 Solution, until submerged in the bast of apocynum, at room temperature, using a high-pressure pump to make FeSO 4 Circulate the solution internally and externally for 15 minutes to empty the FeSO 4 After the solution, pump in a hydrogen peroxide solution with a mass percentage concentration of 0.5%, and circulate it at 30°C for 1 hour. ...

Embodiment 2

[0073] Apocynum bast raw material origin: Xinjiang

[0074] The processing method is as follows:

[0075] Apocynum bast is placed in a closed tank, immersed in dimethylformamide with a mass percentage concentration of 60%, and continuously stirred at room temperature for 20 hours, so that the bast of apocynum is fully infiltrated and activated, and then the tank is The dimethylformamide was vented, and the infiltrated and activated apocynum bast was taken out.

[0076] Then make a cake, the gained apocynum bast and the hemp cage of the cake are placed in the degumming tank together, and the FeCl concentration of 0.1% is pumped into it. 2 solution, until the bast of apocynum was submerged, at room temperature, the FeCl was made by using a high-pressure pump 2 Circulate the solution internally and externally for 30 minutes to empty the FeCl 2 After the solution, pump in a peracetic acid solution with a mass percent concentration of 2.5%, and circulate it at 50°C for 1 hour. A...

Embodiment 3

[0082] Apocynum bast raw material origin: Xinjiang

[0083] Processing method: In addition to FeSO 4 The mass percentage concentration of the solution is 1%, the continuous cooking time of the alkaline degumming solution is 2 hours, the urea peroxide solution is used instead of hydrogen peroxide, and the dimethylacetamide with a mass percentage concentration of 50% is used instead of 40% acetamide. Diamine, the mass percentage concentration of urea peroxide solution solution is outside 1.5%;

[0084] All the other are the same as in Example 1.

[0085] Product inspection test results:

[0086] The obtained apocynum fiber has a residual glue rate of 4.62%, an average fiber length of more than 35mm, a fiber strength of 6.1cN / dtex and a fiber fineness of 3.9dtex.

[0087] It should be noted that the organic amine solvent used in the present invention can also be a mixture of two or three of ethylenediamine, dimethylformamide or dimethylacetamide.

Abstract

The invention discloses a refined processing method of apocynum venetum fiber. The refined processing method comprises steps as follows: wetting activation of apocynum venetum bast, beating into cakes and caging, directional catalytic oxidation, chemical degumming and postprocessing, wherein after the apocynum venetum bast is subjected to wetting activation with organic amine solvents, lignin, pectin and hemicellulose are subjected to the directional catalytic oxidation with a ferrite solution and an activator. A series of technological means including wetting activation processing, the directional catalytic oxidation and the like are organically combined, so that the refined processing method of the apocynum venetum fiber has the characteristics that the degumming effect is good, and a finished apocynum venetum fiber product is good in fineness, length, strength and other indexes, excellent in quality, good in spinnability and the like; besides, the consumption of chemicals during processing is low, the environmental protection pressure is low, and the technology is simple to control; the consumption of utilities such as water, electricity, gas and the like is low, the efficiency is high, and the refined processing method is applicable to industrial production.

Description

technical field [0001] The invention relates to a processing method of hemp fiber, in particular to a refined processing method of apocynum fiber. Background technique [0002] Apocynum, also known as wild hemp, Zeqima, red willow, oleander hemp, etc., is a perennial herbaceous plant belonging to the family Apocynaceae, widely distributed in northern China, concentrated in the Tarim River and Xinjiang Along the Kongque River, it is named for its most abundant growth in the Luobu Plain in Xinjiang. Apocynum fiber has many excellent characteristics, soft to the touch and good luster, has the luster of silk, the lightness of hemp, the softness of cotton, the ductility of velvet, and has pharmacological effects. "King of wild fibers", so it is recognized as an ideal textile fiber. [0003] Apocynum fiber is a kind of bast fiber, which is located in the bast tissue on the stem of apocynum plant, in the form of fiber bundles, and individual fibers exist alone. Apocynum monofila...
