Embodiment 1

[0082] Origin of flax into hemp raw materials: Xinjiang

[0083] The processing method is as follows:

[0084] Put flax into hemp in a steaming ball, a cooking pot or a cooking tank, immerse in the cooking liquid, heat to boiling state, cook for 0.5 hour, and remove impurities by beating flax into hemp.

[0085] Put the boiled flax raw material directly into the steam flash explosion device, heat it so that the water vapor pressure in the steam flash explosion device is 1.0MPa, and keep this pressure for 1 minute; then open the valve and release the pressure quickly;

[0086] Collect the flax fibers ejected from the steam flash explosion equipment, and then make cakes. The flax obtained from the cakes is beaten into hemp and hemp cages are placed in the degumming tank, and FeSO with a mass percentage concentration of 0.05% is pumped into it. 4 Solution, until the flax is covered with flax, at room temperature, the FeSO 4 Circulate the solution internally and externally for 1...

Embodiment 2

[0095] Origin of flax into hemp raw materials: Xinjiang

[0096] The processing method is as follows:

[0097] Put flax into hemp in a steaming ball, a cooking pot or a cooking tank, immerse in the cooking liquid, heat to boiling state, cook for 0.5 hour, and remove impurities by beating flax into hemp.

[0098] Put the boiled flax raw material directly into the steam flash explosion device, heat it so that the water vapor pressure in the steam flash explosion device is 1.5 MPa, and keep this pressure for 5 minutes; then open the valve and release the pressure quickly;

[0099] Collect the flax fibers sprayed from the steam flash explosion equipment, and then make cakes, and put the flax obtained from the cakes into hemp and hemp cages in the degumming tank, and pump FeCl with a mass percentage concentration of 0.1% 2 solution until the flax is submerged, and at room temperature, the FeCl 2 Circulate the solution internally and externally for 30 minutes to empty the FeCl 2 ...

Embodiment 3

[0108] Origin of flax into hemp raw materials: Xinjiang

[0109] Processing method: In addition to FeSO 4 The mass percent concentration of the solution is 1%, the continuous cooking time of the alkaline degumming solution is 2 hours, urea peroxide is used instead of hydrogen peroxide, and the mass percent concentration of the urea peroxide solution is 1.5%;

[0110] All the other are the same as in Example 1.

[0111] Product inspection test results:

[0112] The prepared fine flax fiber has a residual glue rate of 4.12%, an average fiber length of more than 35mm, a fiber strength of 3.3cN / dtex and a fiber fineness of 4.1dtex.

[0113] It should be pointed out that the above-mentioned surfactants can also be, such as: sodium dodecylsulfonate, sodium lauryl sulfate, sodium dodecylbenzenesulfonate, sodium dioctyl sulfosuccinate, lauryl Alcohol sulfate MA24F, sodium secondary alkyl sulfonate SAS60, pull open powder, rapid penetrant T, penetrant JFC, Pingpingjia O, alkylphenol...

Abstract

The invention discloses a refining processing method for linen fiber. The refining processing method comprises the following steps: performing boiling impurity elimination on linen fiber, performing steam explosion activation treatment, performing caking and caging, performing orientated catalytic oxidation, performing chemical degumming, and performing after-treatment. After steam explosion activation treatment, a ferrite solution and an activating agent are adopted to perform orientated catalytic oxidation treatment on lignin, pectin and hemicellulose, and moreover a series of technical methods such as steam explosion degumming treatment and orientated catalytic oxidation are organically combined, so that the refining processing method for the linen fiber, which is disclosed by the invention, has the characteristics that a good degumming effect can be achieved; an obtained linen fiber finished product is good in indexes such as fineness, length and strength, excellent in quality, good in spinnability and the like; and moreover, the refining processing method is small in chemical consumption, small in environment protection burden and simple in process control in processing, and is small in public engineering consumption such as water, electricity and gas, high in efficiency, applicable to industrial production, and good in market popularization prospect.

Description

technical field [0001] The invention relates to a processing method of hemp fiber, in particular to a refined processing method of flax fiber. Background technique [0002] Flax is an annual herb plant, known as the "Queen of Fibers". It is a high-quality natural plant fiber. The history of being used by humans for textiles can be traced back to ancient Egypt. Its single fiber length is 17-25mm, and the single fiber fineness is 12~17μm. Linen fabric has excellent properties such as moisture absorption and quick drying, good air permeability, antibacterial and deodorant, antistatic, ecological and environmental protection, warm in winter and cool in summer. With the continuous improvement of people's living standards, the requirements for the comfort and quality of fabrics will also become higher and higher, so linen textiles will have very broad development and application prospects. [0003] Because flax contains 12-15% hemicellulose, 1.4-5.7% pectin, and 2.5-5% lignin, i...
