Embodiment 1-3

[0023] Embodiment 1-3: a kind of degradable straw fiber, it is characterized in that: described degradable straw fiber is obtained through following processing technology, and this processing technology comprises the following steps:

[0024] Step 1, cutting the straw stalks into several small sections of straw stalks;

[0025] Step 2. Soak the small sections of rice straw in the first soaking solution of 1,4-butanediol with a concentration of 75% to 85% and cook for 100 to 140 minutes at a pressure of 0.8 to 1.0 mp, note this In the steps: the first soaking solution in embodiment 1 is 75%, the pressure is 0.9mp, and the cooking time is 100 minutes; the first soaking solution in embodiment 2 is 85%, the pressure is 0.8mp, and the cooking time is 120 minutes; In example 3, the first soaking solution is 80%, the pressure is 1.0mp, and the cooking time is 140 minutes;

[0026] Step 3, cooling the first soaking solution to 80° C. and filtering to obtain straw fiber. At this tempe...

Abstract

The invention discloses degradable straw fiber. The processing technique of the straw fiber comprises the following steps: soaking a plurality of segments of rice straw in 1,4-butanediol first soaking solution (with the concentration of 75%-85%) for cooking; cooling the first soaking solution to 80 DEG C, and filtering to obtain the straw fiber; drying the straw fiber after being washed in a thermostatic water bath at 80 DEG C; dividing the dried straw fiber into finer fiber bundles with a devillicate machine; soaking the fiber bundles in second soaking solution for treatment; treating the dehydrated fiber bundles with softener; and drying the fiber in a 80 DEG C oven to allow the moisture content of the fiber to be less than 10%, wherein the second soaking solution contains an additive composed of potassium alkyl ether phosphate and polyoxyethylenated castor oil. The degradable straw fiber fully and reasonably uses the rice straw, and the obtained straw fiber has natural adsorption, moisture absorption and heat preservation functions, and is biodegradable.

Description

technical field [0001] The invention relates to a degradable straw fiber, which belongs to the technical field of textile fabrics. Background technique [0002] At present, the annual output of crops in the world is 2 billion tons, and China alone has more than 500 million tons, most of which are rice straw and wheat straw. my country is a large agricultural country and has abundant rice straw resources. Straw, the stalk of rice. Generally refers to the rice stalk after threshing. Rice straw is rich in cellulose, hemicellulose, lignin and so on. [0003] After investigation, it was found that there is a large amount of crop stalks remaining in our country every year. Except a few of these remaining stalks are used as feed, fertilizer, paper, etc., the rest are burned in the wild, which not only wastes a lot of resources, but also damages the natural environment. caused serious pollution. [0004] How to improve the application value of cellulose in rice straw, find more ...
