Abstract

The invention discloses a method for manufacturing cotton from straws, belonging to the field of recycling by-products of crops. The method comprises the following steps: preparing various soak solutions from a proper amount of sulfuric acid, hydrochloric acid, sodium hydroxide, calcium hydroxide, sodium bicarbonate, bleaching powder and the like; respectively soaking, washing and airing straws which are cleaned and chopped into little segments until crude fibers of the straws are softened, brightened and bleached; and then, carding and fluffing into cotton by using a cotton fluffer. The cotton can not be used for spinning and weaving cotton cloth, but can be used in the aspects of manufacturing cotton quilted coats, cotton quilts, sofas and absorbent cotton and the like.

Description

Technical field [0001] The present invention relates to a method for making cotton with rice straw that makes fine use of by-product straws after crops are harvested, in particular to fully utilize rice straw. Background technique [0002] Cotton has a wide range of uses. Cotton clothing, cotton wool, quilts, and cotton swabs all require a large amount of cotton. Therefore, cotton has become the largest economic crop in my country's agricultural products. The cultivation of cotton takes up a large area of ​​arable land, pesticides, fertilizers and manpower. [0003] China is a country with a large population. The planting area of ​​rice, the main food crop in my country, is more than 470 million mu. The large amount of straw after the rice harvest has not been fully and rationally used. A large part of it is even burned in the rice fields, which not only wastes resources , And pollute the atmosphere. Summary of the invention [0004] The technical problem to be solved by the...
