Embodiment 1

[0014] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:

[0015] (1) Pretreatment: Mix rice straw and water at a mass ratio of 1:20, and treat for 2 hours at a temperature of 70°C;

[0016] (2) Mechanical rolling: mechanically rolling the pretreated rice straw twice, and washing with water after rolling;

[0017] (3) Alkali treatment: put the washed rice straw into a sodium hydroxide solution with a mass concentration of 10g / L, and treat it at a temperature of 80°C for 2 hours to obtain rice straw fibers, which are then taken out and washed with water ;

[0018] (4) Hydrogen peroxide treatment: put the alkali-treated rice straw fiber into 2g / L hydrogen peroxide solution, treat it at 50°C for 10 minutes, then take out the rice straw fiber and wash it with water;

[0019] (5) Softening treatment: weigh rice straw fiber and cellulose softener with a mass concentrati...

Embodiment 2

[0023] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:

[0024] (1) Pretreatment: Mix rice straw and water at a mass ratio of 1:30, and treat for 1 hour at a temperature of 80°C;

[0025] (2) Mechanical rolling: the pretreated rice straw is mechanically rolled 3 times, and washed with water after rolling;

[0026] (3) Alkali treatment: put the washed rice straw into a sodium hydroxide solution with a mass concentration of 20g / L, and treat it for 2 hours at a temperature of 100°C to obtain rice straw fibers, which are then taken out and washed with water ;

[0027] (4) Hydrogen peroxide treatment: Put the alkali-treated rice straw fiber into 6g / L hydrogen peroxide solution, treat it at 60°C for 5 minutes, then take out the rice straw fiber and wash it with water;

[0028] (5) Softening treatment: weigh rice straw fiber and cellulose softener with a mass concentra...

Embodiment 3

[0032] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:

[0033] (1) Pretreatment: Mix rice straw and water at a mass ratio of 1:40, and treat for 1 hour at a temperature of 90°C;

[0034] (2) Mechanical rolling: the pretreated rice straw is mechanically rolled 3 times, and washed with water after rolling;

[0035] (3) Alkali treatment: put the washed rice straw into a sodium hydroxide solution with a mass concentration of 30g / L, and treat it for 3 hours at a temperature of 90°C to obtain rice straw fibers, which are then taken out and washed with water ;

[0036] (4) Hydrogen peroxide treatment: Put the alkali-treated rice straw fiber into 6g / L hydrogen peroxide solution, treat it at 60°C for 15 minutes, then take out the rice straw fiber and wash it with water;

[0037] (5) Softening treatment: weigh rice straw fiber and cellulose softener with a mass concentra...

Abstract

The invention relates to a method for preparing a natural cellulose fiber by taking rice straws as the raw material, which comprises the following steps: pretreatment, mechanical rolling, alkali treatment, hydrogen peroxide treatment, softening treatment, humidifying, stewing, and carding. As the rice straws are used as the raw material for preparing the natural cellulose fiber, the problem of rare application of rice straws as the textile raw material in the textile industry is solved; furthermore, since the rice resources in China are rich and can be recycled, not only the problem of environmental pollution caused by improper utilization of rice straws in China can be reduced, but also the energy is saved, and the resource utilization ratio is higher.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing natural cellulose fibers from rice straws. Background technique [0002] my country is a large agricultural country with a large amount of rice resources, and the distribution of domestic rice is relatively wide. The annual output of straw in my country reaches 700 million. Rice belongs to the grass family, of which rice straw accounts for about 27.5%. However, the utilization rate of abundant rice straw resources in my country is very low. Rice straw is a natural renewable polymer resource, which can be utilized as a resource to develop environmentally friendly green products. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing natural cellulose fibers using rice straw as a raw material, so as to solve the problem that rice straw is rarely used as a textile raw ...
