Embodiment 1
[0028] The invention discloses a preparation process of environment-friendly sugarcane husk fiber; the preparation process comprises the following steps:
[0029] (1) First remove the sugarcane skin and cut the transverse section into 50-75mm long pieces, wash them in clean water, then boil them in a water bath for 1-2 hours according to the bath ratio of 1:30, and repeat after replacing the clean water Boiling treatment 1-3 times, drying;
[0030] (2) According to the bath ratio of 1:20, under the condition of stirring at a temperature of 80°C, place the dried sugarcane skin in a mixed solution of hydrochloric acid and formic acid for treatment to extract sugarcane skin fibers; in the mixed solution , by mass percentage, the concentration of hydrochloric acid is 0.8%, the concentration of formic acid is 8%, and the treatment time is 20min;
[0031] (3) Wash the obtained sugarcane husk fiber with water, then place it in an alkaline solution for alkali boiling treatment at a t...

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 ...
