Problems solved by technology

[0004] To sum up, the current production process of lotus fiber mainly has problems such as uneven fiber quality, large differences in properties, high production labor intensity, and high labor costs.
Direct manual extraction or manual extraction after biological fermentation and alkali boiling pretreatment can separate the lotus stalk epidermis very well, but the production efficiency is low
The lotus fiber is produced by alkali boiling and degumming. The obtained lotus fiber is rough and has poor performance, and the way of manually peeling off the skin is still not conducive to improving production efficiency.

Embodiment 1

[0052] Weigh 20g of dried lotus stalks and organize them into 5cm long segments. Prepare 1L of sodium hydroxide solution with a concentration of 20g / L, add 3g of sodium silicate and 2g of sodium tripolyphosphate. In an oil bath at 90°C for 4h. After the reaction was completed, the sample was taken out, washed 3 times with distilled water, and then soaked in distilled water for 3 h. Take out the sample, wash away the tissue between the lotus stalk fiber and the epidermis through mechanical extrusion, rinse with a 2mm sieve to remove impurities such as sediment, repeat this operation until the filtrate is neutral, and the sediment in the filtrate basically disappears. ℃ drying 24h. Weigh the sample, add 12g of sodium chlorite and 6mL of glacial acetic acid per gram of sample, add distilled water, seal the container, and place it in an oil bath at 70°C for 3 hours. Wash the sample with distilled water until neutral, crush the epidermal tissue by mechanical extrusion, rinse wit...

Embodiment 2

[0056] Weigh 20g of dried lotus stalks and organize them into 5cm long segments. Prepare 1L of sodium hydroxide solution with a concentration of 20g / L, add 3g of sodium silicate and 2g of sodium tripolyphosphate. Set the ultrasonic power to 140W, and ultrasonicate at 70°C for 30min. After the reaction was completed, the sample was taken out, washed 3 times with distilled water, and then soaked in distilled water for 3 h. Take out the sample, wash away the tissue between the lotus stem fiber and the epidermis through mechanical extrusion, rinse with a 2mm sieve to remove impurities such as sediment, repeat this operation until the filtrate is neutral, and the sediment in the filtrate basically disappears. ℃ drying 24h. Weigh the sample, add 12g of sodium chlorite and 6mL of glacial acetic acid per gram of the sample, add distilled water, seal the container, set the ultrasonic power to 140W, and heat in a water bath at 60°C for 20 minutes. Wash the sample with distilled water...

Abstract

The invention provides a technique for preparing lotus fiber by a joint process and belongs to the field of fiber extraction and processing. The technique mainly comprises material sorting, chemical treatment, mechanical separation, and fiber post-finishing. The chemical treatment mainly includes: degumming and removing impurities with a strong alkali, and dissolving lignin and skin with chlorite solution to obtain lotus fiber 3-6 Mum in diameter, with impurity removal rate reaching 85% and above. The technique employs chemical treatment and mechanical processing in conjunction with ultrasonic technology to effectively destroy the skin of lotus stems, and the production efficiency is improved. The technique has high efficiency, simple process and good operational simplicity, is low in production cost and short in production cycle, is a novel, efficient, scientific and operable lotus fiber preparation process and has a promising application prospect.

Description

technical field [0001] The invention belongs to the field of novel natural fiber materials, in particular to the extraction and preparation process of natural fibers, in particular to the preparation process of lotus fiber. Background technique [0002] As people pay more and more attention to health and environmental protection, the demand for green, safe and environment-friendly textile fabrics is increasing year by year. Natural plant fibers have the characteristics of health and safety, renewable resources, and easy degradation, so they are recognized as green and environmentally friendly materials. Natural plant fiber materials have good hydrophilicity, no pilling, antistatic, comfortable and breathable, and are popular clothing fabrics. At present, the production of natural plant fibers such as cotton, hemp, and bamboo has been very mature. Lotus, also known as lotus, lotus, etc., is widely planted in Asia such as China, Myanmar, and Thailand. At present, it is mainl...
