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
The present invention relates to a kind of byproduct stalk after the crops results be carried out meticulous utilization, particularly a kind of method of making cotton of straw that the straw of paddy rice is made full use of.
Background technology
Cotton of many uses, cotton dress, cotton-wool, cotton-wadded quilt, cotton swab all need a large amount of cottons, thereby cotton becomes industrial crops maximum in the agricultural products in China, the plantation of cotton accounted for large-area arable land, agricultural chemicals, fertilizer and manpower.
China is a populous nation, the cultivated area of China staple food crop paddy rice is more than 4.7 hundred million mu, and a large amount of straw after the rice harves all also are not used adequately reasonably, even to have be to burn in the rice field greatly, this has not only wasted resource, and atmosphere is polluted.
Summary of the invention
The technical problem to be solved in the present invention is that the byproduct straw after the rice harves is processed into cotton.
The technology used in the present invention measure is:
1, straw is cleaned, dried, it is long to be cut into 6-8cm, immerses " No. 1 soak " and soaks 2 days, stirs every now and then and stirs, and pulls out to drain;
2, immerse again in " No. 2 soaks ", move in the enamel pan and boiled 2 hours, pull out and drain, colourless with the clear water cyclic washing, feel is sliding to washing lotion, dry;
3, immerse in " No. 3 soaks " 6 hours after 2 days, stir every now and then and stir, pull out and drain, with the clear water washing to neutral;
4, adding " No. 4 soaks " is bleached, and just floats and stirs half an hour, pulls out to drain, and, dries to neutral with the clear water washing;
5, with hot-water soak 4 hours (or boil 1 hour with clear water), dry, multiplexing " No. 4 soaks " floated 15 minutes, and the clear water washing is dried to neutral;
6, immersed " No. 5 soaks " softening 2 days, stir frequently, pull out and drain, to neutral, dry, immersed in the 0.5% hot soap lye 2 days with the clear water washing, treat the fiber light after, pull out and drain, sun dehydration promptly gets cotton with cotton fluffer comb bullet.
" No. 1 soak " is formulated by 1 part of sodium carbonate, 30 parts of saturated lime clear aqueous solutions, 69 parts of clear water.
" No. 2 soaks " is formulated by 1 part of NaOH, 20 parts of saturated limewaters, 3 parts of concentrated ammonia liquors and 76 parts of clear water.
" No. 3 soaks " is formulated by 1.2 parts of sulfuric acid, 0.05 part of hydrochloric acid, 99.75 parts of clear water.
" No. 4 soaks " is by 1 part of bleaching powder, 1 part of refined salt, 2 parts of sodium bicarbonates, 0.5 part of sulfuric acid, 95.5 parts of bleaching liquid that clear water is formulated.
" No. 5 soaks " is formulated by 2.2 parts of turkey red oils, 0.3 part of sulfuric acid, 97.5 parts of clear water.
Beneficial effect of the present invention: the cotton with straw is made though can not be used to spin cotton and weave cloth, can be widely used in and make cotton dress, cotton-wadded quilt, mattress, sofa, absorbent cotton etc.The agricultural byproducts straw that this invention not only will often go out of use is made cotton, so also can save the arable land of many plant cottons.
The specific embodiment
Get an amount of straw, clean, dry, it is long to be cut into about 7cm, immerses by in the formulated soak of 1.2 parts of sulfuric acid, 0.05 part of hydrochloric acid, 99.75 parts of clear water, soaks 2 days, and stirring is stirred every now and then, pulls out to drain;
Immerse again by in 1 part of NaOH, 20 parts of saturated limewaters, 3 parts of concentrated ammonia liquors and the 76 portions of formulated soaks of clear water, move in the enamel pan and boiled 2 hours, pull out and drain, colourless with the clear water cyclic washing, feel is sliding to washing lotion, dry; Immerse after 2 days by in 1.2 parts of sulfuric acid, 0.05 part of hydrochloric acid, the 99.75 portions of formulated soaks of clear water 6 hours, stir every now and then and stir, pull out and drain, with the clear water washing to neutral; Adding is just floated and is stirred half an hour by bleaching in the formulated bleaching liquid of 1 part of bleaching powder, 1 part of refined salt, 2 parts of sodium bicarbonates, 0.5 part of sulfuric acid, 95.5 parts of clear water, pulls out to drain, and, dries to neutral with the clear water washing; With hot-water soak 4 hours (or boil 1 hour with clear water), dry, multiplexing by bleaching 15 minutes in the formulated bleaching liquid of 1 part of bleaching powder, 1 part of refined salt, 2 parts of sodium bicarbonates, 0.5 part of sulfuric acid, 95.5 parts of clear water, the clear water washing is dried to neutral; Immersion is stirred frequently by 2.2 parts of turkey red oils, 0.3 part of sulfuric acid, 97.5 parts of formulated soak softenings of clear water 2 days, pull out to drain, with the clear water washing to neutral, dry, immersed in the 0.5% hot soap lye 2 days, treat the fiber light after, pull out and drain, sun dehydration promptly gets cotton with cotton fluffer comb bullet.
