Embodiment 1

[0033] Choose annual bamboo. Use a punching machine or other methods to perforate, or use a machine to cut the cylindrical bamboo into two halves to make the bamboo into a hollow cylindrical or semi-cylindrical shape,

[0034] The flattened bamboo is impregnated with flame retardant treatment,

[0035] Impregnation flame retardant treatment adopts vacuum pressure flame retardant treatment: during the treatment process, the bamboo material is first put into a vacuum pressure tank and evacuated to make the vacuum degree -0.015MPa, and then the flame retardant is added into the tank and the inner pressure of the tank is increased to 0.1MPa, the flame retardant used is composed of the following components in parts by weight: 20 parts of ammonium oligophosphate, 10 parts of ammonium phosphate, 6 parts of ammonium pyrophosphate, 5 parts of ammonium sulfate, 5 parts of boric acid, and 10 parts of water; Next, soften the bamboo,

[0036] Immerse the bamboo material after the impregn...

Embodiment 2

[0043] Choose two-year-old green bamboo.

[0044] Perforate with a punching machine or other methods, or cut the cylindrical bamboo into two halves with a machine to make the bamboo into a hollow cylindrical or semi-cylindrical shape, and impregnate the flattened bamboo with flame retardant treatment.

[0045]Impregnation flame retardant treatment adopts vacuum pressure flame retardant treatment: in the treatment process, the bamboo filamentous fibers obtained after fiber opening are first put into a vacuum pressure tank and evacuated to make the vacuum degree -0.025Mpa, and then the flame retardant is added to the tank The internal pressure of the tank is increased to 0.8Mpa, and the flame retardant used is composed of the following components in parts by weight: 50 parts of ammonium oligophosphate, 25 parts of ammonium phosphate, 12 parts of ammonium pyrophosphate, 20 parts of ammonium sulfate, 10 parts of boric acid, 25 parts of water; then soften the bamboo,

Embodiment 3

[0053] Choose three-year-old green bamboo. Use a punching machine or other methods to perforate, or use a machine to cut the cylindrical bamboo into two halves to make the bamboo into a hollow conical or semi-conical shape, and impregnate the flattened bamboo for flame retardant treatment.

[0054] Impregnation flame retardant treatment adopts vacuum pressure flame retardant treatment: in the treatment process, the bamboo filamentous fibers obtained after fiber opening are first put into a vacuum pressure tank and vacuumed to make the vacuum degree -0.02Mpa, and then the flame retardant is added to the tank The pressure inside the tank is increased to 0.6Mpa, and the flame retardant used is composed of the following components in parts by weight: 30 parts of ammonium oligophosphate, 15 parts of ammonium phosphate, 8 parts of ammonium pyrophosphate, 15 parts of ammonium sulfate, 8 parts of boric acid, 15 parts of water; then soften the bamboo,

Abstract

The invention relates to a preparation method of bamboos, in particular to a preparation method for directly producing natural bamboo fibers for towels with bamboos. The preparation method sequentially comprises the following steps of: sorting, flattening, impregnating flame retardant treatment, softening, splitting, cooking, acid washing, bleaching and curing, wherein in the step of impregnating flame retardance treatment, vacuum pressure flame retardant treatment is adopted, in the treatment process, firstly the flattened bamboos are filled into a vacuum pressure tank, the vacuum pressure tank is vacuumized so that the vacuum degree is -0.015 to -0.025Mpa, then a flame retardant is added to the tank and the pressure in the tank is increased to 0.1-0.8Mpa; in the step of softening, microwave softening is adopted, the bamboos subjected to impregnating flame retardant treatment are soaked in softening solution and then are sent into a microwave vacuum tank and then microwave softening treatment is carried out; and in the step of cooking, the bamboo filament shaped fibers are put in cooking solution and repeated pressure increase and reduction operations are carried out in a pressure tank body. The preparation method has the advantages that the preparation method is simple and convenient in production and short in treatment time; and the produced bamboo fibers have flame retardant effect.

Description

technical field [0001] The invention relates to a method for preparing bamboo, in particular to a method for directly producing bamboo fibrils for towels by using original bamboo. Background technique [0002] There are two types of bamboo fibers currently on the market: one is the regenerated fiber produced from bamboo pulp, usually called bamboo pulp fiber; the other is the fiber directly extracted from bamboo through a special process, called bamboo fibril. Because bamboo fiber has more superior properties in hygroscopicity, air permeability, spinnability, etc., the study of spinnable bamboo fiber has obvious economic and social benefits. [0003] In recent years, there have been many invention patents in my country on the manufacturing method of raw bamboo fibers. CN11078520C announced a method of slitting, rolling, and forming bamboo fiber bundles from raw bamboo. CN1261290C announced a method of using pure bamboo In the physical method, the bamboo fibers are made into ...
