Embodiment 1

[0038] Choose annual moso bamboo. Use a perforator or other methods to perforate, or use a machine to cut the cylindrical bamboo into two halves, so that the bamboo becomes a hollow cylinder or a semi-cylindrical tube, soak the flattened bamboo in the softening liquid, and the bamboo and the softening liquid The weight ratio is 100:8, and the softening solution is mixed with 100 parts by weight of water, 15 parts of milk mother soap, 8 parts of mineral oil and 5 parts of emulsifier OP;

[0039] Then put the bamboo soaked in the softening solution into a microwave vacuum tank, evacuate until the vacuum degree is -0.02MPa, and then perform microwave softening treatment, the microwave frequency is 300MHz, and the microwave treatment time is 1min;

[0040] After the softened bamboo is rinsed with water, it is combed, and then the bamboo is made into a fiber bundle by a fiber separator; then steamed,

[0041] The cooking method is to place the fiber-opened bamboo filaments in the ...

Embodiment 2

[0045] Choose biennial green bamboo.

[0046] Use a perforator or other methods to perforate, or use a machine to cut the cylindrical bamboo into two halves, so that the bamboo becomes a hollow cylinder or a semi-cylindrical tube, soak the flattened bamboo in a softening solution, and the bamboo and the softened The weight ratio of the liquid is 100:2, and the softening liquid is mixed with 100 parts by weight of water, 20 parts of milk soap, 10 parts of mineral oil and 8 parts of Pingping plus O emulsifier;

[0047] Then put the bamboo soaked in the softening solution into a microwave vacuum tank, evacuate until the vacuum degree is -0.001MPa, and then perform microwave softening treatment, the microwave frequency is 950MHz, and the microwave treatment time is 3min;

[0048] After the softened bamboo is rinsed with water, it is combed, and then the bamboo is made into a fiber bundle by a fiber separator; then steamed,

[0049] The cooking method is to place the fiber-opened ...

Embodiment 3

[0053] Choose three-year-old green bamboo. Use a puncher or other methods to perforate, or use a machine to cut the cylindrical bamboo into two halves, so that the bamboo becomes a hollow conical or semi-conical shape, soak the flattened bamboo in the softening solution, and the bamboo and the softened The weight ratio of the liquid is 100:5, and the softening liquid is mixed with 100 parts by weight of water, 18 parts of milk soap, 9 parts of mineral oil and 6 parts of emulsifier OP;

[0054] Then put the bamboo soaked in the softening solution into a microwave vacuum tank, evacuate until the vacuum degree is -0.01MPa, and then perform microwave softening treatment, the microwave frequency is 600MHz, and the microwave treatment time is 2min;

[0055] After the softened bamboo is rinsed with water, it is combed, and then the bamboo is made into a fiber bundle by a fiber separator; then steamed,

[0056] The cooking method is to place the fiber-opened bamboo filaments in the c...

Abstract

The invention relates to a manufacturing method of bamboo fiber and particularly relates to a method for directly producing raw bamboo fiber from raw bamboos. The method sequentially comprises the following steps of: selecting materials, flattening, softening, opening, performing steam boiling, acid cleaning, dipping flame-retardant treatment and bamboo vinegar treatment and drying, wherein the softening adopts microwave softening, the bamboo material after flattening is soaked in softening liquor, then the bamboo material dipped with the softening liquor is sent into a microwave vacuum tank, and microwave softening treatment is further performed; the dipping flame-retardant treatment adopts vacuum pressurization flame-retardant treatment, during the treatment process, bamboo filament-like fiber obtained after opening is firstly arranged into a vacuum pressurization tank, vacuum-pumping operation is performed to enable the vacuum degree to be minus 0.015MPa-minus 0.025MPa, and then a flame retardant is added into the tank to increase the pressure in the tank to be 0.1MPa-0.8MPa; and the bamboo vinegar treatment comprises primary bamboo vinegar treatment and secondary bamboo vinegar treatment. The manufacturing method disclosed by the invention has the advantages of simplicity and convenience in production and short treatment time, and the produced bamboo fiber has a flame-retardant effect.

Description

technical field [0001] The invention relates to a method for manufacturing bamboo fiber, in particular to a raw bamboo fiber directly produced from raw bamboo. Background technique [0002] Bamboo fiber currently on the market has the following two classes: one is the regenerated fiber produced from bamboo pulp, commonly referred to as bamboo pulp fiber; the other is the fiber directly extracted from bamboo through a special process, called raw bamboo fiber. Because bamboo fiber has more superior properties in terms of hygroscopicity, air permeability, and spinnability, the study of spinnable bamboo fiber has obvious economic benefits and good social benefits. [0003] In recent years, my country has had many invention patents in the bamboo raw fiber manufacturing method, CN11078520C announced a kind of raw bamboo strips, rolling strips, the manufacture method of forming bamboo fiber bundle products, CN1261290C announced a kind of raw bamboo bamboo slices using pure physical...
