Problems solved by technology

[0003] Fibrous okra refers to the okra that missed the best picking time, has increased fiber, and has aged okra. This kind of okra has lost its commercial value and can only be discarded or used as feed. The best harvest time for okra is flowering 7-8 days after thanking, the time is very short. Once missed, it is easy to fibrate and is no longer popular in the market. Usually, for okra planted in large areas, the best harvest time cannot be unified. Most of them have been fibrous, and throwing them away will bring great losses to farmers. Therefore, it is very important for farmers to develop the added value of fibrous okra, and it can also make full use of the country's biomass resources.

Embodiment 1

[0029] Prepare okra colored viscose fiber 1, following steps:

[0030] Step 1. Preparation: Take 200 kg of okra 17 days after flowering and put it in boiling water for 20 minutes, take it out and dry it at 70°C, grind it into 30-mesh okra powder, add it to the same mass fraction as the okra powder with a mass fraction of 60 % ethanol aqueous solution, after soaking for 30min, dry at 50°C, add 1 times the mass fraction of okra powder to 5% CuSO4 aqueous solution, soak at 40-50°C for 20-30min, then dry at 50°C Dry, wash with water to remove residual copper sulfate, filter, and dry at 50°C again to obtain 38.1kg of secondary okra powder;

[0031] Step 2, preparing nanofibers: put the secondary okra powder obtained in step 1 into a ball mill and add a mass fraction of 1.2% dihydrolipoic acid aqueous solution to grind for 25 hours. The quality of the dihydrolipoic acid aqueous solution is six times that of the okra powder. 12 hours to obtain nanofiber powder with a particle size o...

Embodiment 2

[0043] Prepare okra colored viscose fiber 2, following steps:

[0044] Step 1. Preparation: Take 200 kg of okra 20 days after flowering and put it in boiling water for 30 minutes, take it out and dry it at 50°C, grind it into 50-mesh okra powder, add it to the same mass fraction as the okra powder with a mass fraction of 60 % ethanol aqueous solution, after soaking for 30min, dry at 60°C, add 5% CuSO4 aqueous solution whose mass fraction is 2 times that of okra powder, soak at 40°C for 30min, then dry at 50°C, wash with water to remove Copper sulfate residue, filter, and dry again at 50°C to obtain 39.4kg of secondary okra powder;

[0045] Step 2, preparing nanofibers: put the secondary okra powder obtained in step 1 into a ball mill and add a mass fraction of 1% dihydrolipoic acid aqueous solution to grind for 20 hours. The quality of the dihydrolipoic acid aqueous solution is four times that of the okra powder. 12 hours to obtain nanofiber powder with a particle size of 20-...

Embodiment 3

[0057] Prepare okra colored viscose fiber 3, following steps:

[0058] Step 1. Preparation: Take 200 kg of okra 15 days after flowering and put it in boiling water for 10 minutes, take it out and dry it at 80°C, grind it into 50-mesh okra powder, add it to the same mass fraction as the okra powder with a mass fraction of 60 % ethanol aqueous solution, after soaking for 30min, dry at 60°C, add 1 times the mass fraction of okra powder to 5% CuSO4 aqueous solution, soak at 40°C for 30min, then dry at 50°C, and wash to remove Copper sulfate remains overnight, filtered, and dried at 50°C again to obtain 36.1kg of secondary okra powder;

[0059] Step 2, preparing nanofibers: put the secondary okra powder obtained in step 1 into a ball mill and add a mass fraction of 2% dihydrolipoic acid aqueous solution to grind for 30 hours. The quality of the dihydrolipoic acid aqueous solution is four times that of the okra powder. 12 hours to obtain nanofiber powder with a particle size of 20-...

Abstract

The invention discloses a preparation method of an okra colored viscose fiber and an obtained leisure wear and belongs to the technical field of textiles. The preparation method comprises the steps that fibrotic okra is picked for material preparation, nano fiber preparation, alkalization, yellowing, dissolution, filtration, deaeration and spinning are performed, and the viscose fiber and the leisure wear are manufactured through a post-treatment process. The okra is used as the raw material to manufacture the viscose fiber leisure wear, a novel raw material is provided for preparation of the viscose fiber, the diversity of the viscose fiber is enriched, the shortage of viscose fiber resources is decreased, waste is turned into wealth, the added value of the fibrotic okra is played, farmers' losses are redeemed, and conditions are created for income increase. The viscose fiber has its color and does not need later dyeing, and skin injury caused by chemical reagent residues in the dyeing process is avoided.

Description

technical field [0001] The invention belongs to the technical field of textiles, and more specifically relates to a preparation method of okra colored viscose fiber and home clothes obtained therefrom. Background technique [0002] With the improvement of people's living standards and the impact of the world's energy crisis, people gradually realize the advantages of natural environmental protection materials, especially the demand for natural environmental protection materials for clothing is increasing, and the fabric can be naturally degraded after being discarded. Viscose fibers account for a considerable proportion. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber is most in line with the physiological requirements of human skin, and it has the characteristics of smooth and cool, breathable, antistatic, and brilliant dyeing. At present, the main raw materials that p...
