Embodiment 1

[0052] Beat flax into hemp and put it in the pickling pool, add 10 kg of water per kg of flax (bath ratio 1:10), add sulfuric acid to make the concentration of sulfuric acid 1g / L. Raise the temperature of the solution to 40°C, keep it warm for 40 minutes, take it out and wash the flax fiber with clean water, so that the pH value of the flax fiber reaches about 7; put the washed flax fiber into the oxidation solution, the bath ratio is 1:10, and oxidize Hydrogen peroxide in liquid (by pure H 2 o 2 Calculation) content is 3g / L, sodium silicate content is 3g / L, potassium carbonate content is 2g / L, urea content is 3g / L, JFC content is 2g / L. Raise the temperature of the oxidizing solution from room temperature to 70°C at a constant speed, and control the heating time at 30 minutes. After reaching the temperature, let the oxidizing solution keep warm for 2 hours; beat the oxidized flax fiber twice with a wooden mallet; The flax fiber is cleaned to remove the medicines and impuriti...

Embodiment 2

[0057] Beat flax into hemp and put it in the pickling pool, add 10 kg of water per kg of flax (bath ratio 1:10), add sulfuric acid to make the concentration of sulfuric acid 2g / L. Raise the temperature of the solution to 50°C, keep it warm for 45 minutes, take it out and wash the flax fiber with clean water, so that the pH value of the flax fiber reaches about 7; put the washed flax fiber into the oxidation solution, the bath ratio is 1:10, Hydrogen peroxide in liquid (by pure H 2 o 2Calculation) content is 4g / L, sodium silicate content is 4g / L, sodium carbonate content is 3g / L, urea content is 4g / L, JFC content is 2g / L. Raise the temperature of the oxidizing solution from normal temperature to 80°C at a constant speed, and control the heating time at 32 minutes. After the temperature reaches, let the oxidizing solution keep warm for 2.2 hours; beat the oxidized flax fiber with a wooden mallet twice; The flax fiber is cleaned to wash away the medicines and impurities remaini...

Embodiment 3

[0062] Beat flax into hemp and put it in the pickling pool, add 10 kg of water per kg of flax (bath ratio 1:10), add sulfuric acid to make the concentration of sulfuric acid 1.5g / L. Raise the temperature of the solution to 42°C, keep it warm for 50 minutes, take it out and wash the flax fiber with clean water, so that the pH value of the flax fiber reaches about 7; put the washed flax fiber into the oxidation solution, the bath ratio is 1:10, and oxidize Hydrogen peroxide in liquid (by pure H 2 o 2 Calculation) content is 5g / L, sodium carbonate content is 4g / L, sodium silicate content is 5g / L, urea content is 5g / L, JFC content is 2g / L. Raise the temperature of the oxidizing solution from room temperature to 90°C at a constant speed, and control the heating time at 34 minutes. After reaching the temperature, let the oxidizing solution keep warm for 2.4 hours; beat the oxidized flax fibers with a wooden mallet for 5 times; The flax fiber is cleaned to wash away the medicines a...

Abstract

The invention relates to a flax fiber. The flax fiber has a strength of 3.0-8.0 cN / dtex and a fineness of 1500-3500 males; preferably has a strength of 4.0-7.0 cN / dtex and a fineness of 1500-3000 males; more Preferably, the strength is 4.5 to 6.5 cN / dtex, and the fineness is 1800 to 2800 males; the most preferred is the strength of 5.0 to 6.0 cN / dtex, and the fineness is 2300 to 2700 males. The invention also relates to the preparation method of the flax fiber, which includes the steps of pickling, washing, oxidizing, beating, oiling, de-oiling water, softening hemp, oiling and humidifying, stacking bins and mechanically opening. The flax fiber provided by the invention has high strength and fineness, and the preparation method has short process and little pollution.

Description

technical field [0001] The invention belongs to the textile field, in particular, the invention relates to a flax fiber and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to fashion styles such as moisture absorption, breathability, health care, crispness, and green environmental protection of clothing fabrics, which prompts people to strengthen the reuse and development of natural fiber resources. Flax fiber is an excellent textile raw material. Its fabric has unique styles such as good moisture absorption and heat dissipation, good air permeability, natural texture, soft luster, crisp and generous, which makes it highly preferred by consumers. [0003] At present, the domestic flax spinning factory mainly adopts the wet spinning method, that is, flax is first beaten into flax (the fineness is coarse, about 200-300 public branches) to produce roving through carding, needle combin...
