Embodiment 1

[0033] a) Pretreatment process: adding water and sulfuric acid with a weight concentration of 80% to the okra stalks, soaking at room temperature for 1 hour, and then washing with water to neutrality, the weight ratio of the okra stalks to water and sulfuric acid is 1:10:0.015;

[0034] b) Biological extraction process: add biological enzyme BTM to the okra stalks processed in the pretreatment process, its activity index is greater than 3000BSU / g, penetrant JFC, urea, water, react for 4 hours under the condition of 50 ℃, and then use The water machine can be washed for 5 minutes. The weight ratio of okra straw to biological enzymes, penetrants, urea, and water is 1:0.1:0.01:0.01:10;

[0035] c) Alkaline extraction process: Add caustic soda, penetrant, sodium silicate, urea, water to the okra stalk extracted by the biological process, react at 85°C for 2 hours, add hydrogen peroxide with a weight concentration of 30%, and react for 1 hour , wash with a water machine for 5 minut...

Embodiment 2

[0042] a) Pretreatment process: add water and 90% sulfuric acid by weight concentration to okra stalks, soak at room temperature for 1.5 hours, then wash with water until neutral, the weight ratio of okra stalks to water and 90% sulfuric acid by weight concentration is 1: 15:0.02;

[0043] b) Biological extraction process: add penetrant JFC, urea, water, biological enzyme BTM and Bacillus subtilis CGMCC1.942 to the okra straw treated in the pretreatment process, BTM biological enzyme and Bacillus subtilis CGMCC1. The volume ratio of the 942 expanded culture solution is 1:0.5, the activity index of biological enzyme BTM and Bacillus subtilis CGMCC1.942 is greater than 3000BSU / g, react at 55°C for 4.5 hours, and then use a water pump to beat Just wash for 5 minutes, the weight ratio of okra stalks to biological enzyme BTM and Bacillus subtilis, penetrant, urea, and water is 1:0.12:0.02:0.02:15;

Abstract

The invention discloses a method for preparing natural fiber by okra straws, comprises the following processes of: a) pretreatment process; b) biological extraction process; c) alkali extraction process; d) acid cleaning process; e) suppleness process; f) drying process; g) softening process; h) extending and carding. Compared with the prior art, the invention uses the okra straws which are resourceful and low in cost as the raw material to prepare spinnable long fiber with biodegradability, environmental friendliness and good skin friendliness through the degumming technology combined with the development of biology and chemical degumming with short processing time.

Description

technical field [0001] The invention belongs to a method for preparing natural fibers by using plant stalks, in particular to a method for preparing natural fibers by using yellow and red okra stalks as raw materials. Background technique [0002] Okra, also known as okra, okra, coffee ambrette, etc., belongs to the annual herb of Malvaceae. It is native to tropical regions such as Africa, the Middle East, India, Sri Lanka and Southeast Asia, and is now introduced all over the world. People's attention to okra is based on its nutritional value, and the tender fruit, leaves, buds and flowers of okra are all edible. Its dry seeds can also extract oil and protein, and can also be used as a coffee substitute or additive. Its flowers, seeds and roots can be used as medicine. It has curative effect on malignant sore tumors. Okra is rich in nutrition, and the young fruit contains a lot of sticky juice and has a special fragrance. Its juice is mixed with pectin, bovine lactan a...
