Preparation process of environment-friendly sugarcane peel fibers

Abstract

The invention discloses a preparation process of environment-friendly sugarcane peel fibers. The preparation process comprises the following steps of: (1), firstly, removing sugarcane peels and transversely cutting the sugarcane peels into small sections with the length of 50mm-75mm; putting the sugarcane peels into clean water and washing; then putting the sugarcane peels into a water batch at the bath ratio of 1 to 30, and boiling for 1-2 hours; replacing the clean water and repeatedly boiling for 1-3 times, and drying; (2) putting the dried sugarcane peels into a mixed solution of hydrochloric acid and formic acid under a stirring condition that the temperature is 80-90 DEG C at the bath ratio of 1 to (20-35), and extracting the sugarcane peel fibers; (3) washing the obtained sugarcane peel fibers with water, and putting the sugarcane peel fibers into an alkaline solution under a stirring condition that the temperature is 75-80 DEG C at the bath ratio of 1 to (20-35) and carrying out alkali boiling treatment; and (4) putting the sugarcane peel fibers subjected to the alkali boiling treatment into a weak acid solution and carrying out neutralizing treatment, and washing with the water and drying to obtain 50%-70% of sugarcane peel single fibers, with the residue of bundle fibers. The sugarcane fibers prepared by the invention have strong moisture absorption and air permeability, good rigidness and softness and strength elongation property, and are environmentally friendly and biodegradable.

Description

technical field [0001] The invention relates to a preparation process of fiber, in particular to a preparation process of environment-friendly sugarcane husk fiber. Background technique [0002] With the continuous advancement of the pace of the times, the shortage of global energy sources, the development of synthetic fibers with petroleum as the main raw material has also been restricted to a certain extent; the total production of cotton still cannot meet the production needs of the textile industry, and textiles such as wool and hemp Raw materials also need to be imported in large quantities; in this case, it is of practical significance to explore and develop a new cellulose fiber. [0003] Our country has a long history of planting sugarcane and utilizing sugarcane to make sugar, and the yield of sugarcane is relatively high. Sugarcane husk can be taken directly for use, which is rich in resources. In recent years, countries around the world are accelerating the pace ...

AI Technical Summary

Problems solved by technology

Studies have shown that sugarcane husk fiber has better performance than bagasse fiber-reinforced composite materials; sugarcane husk, which accounts for about 20% of the entire sugarcane mass, has not been studied much and has not been well utilized so far.
