Description
Technical field
The present invention relates to the textile raw material processing technique field, is a kind of preparation method of broussonetia fibre for weaving specifically.
Background technology
Light leaf paper mulberry is the broad-leaved assortment, and adaptability is extremely strong, and cultivation easily.Happiness light, drought-resistant, salt tolerant alkali, well developed root system, germinating ability are strong, at barren soil well-growns such as hills, river shoals.Except that high and cold region growings such as China Qinghai, Tibet are bad, the most of regional well-grown in the whole nation.The maximum characteristics of light leaf paper mulberry are exactly that growth cycle is extremely short, plant then, just can fell utilization then, plant in 1 year, can sprout regeneration after results, and its root are for many years cut down.And be convenient to results, processing, transportation, storage, and the production efficiency height, relative cost is lower.
Broussonetia white bast portion fiber belongs to bast fiber, and its chemical composition characteristics are: the content of cellulose height, white sheath fibers cellulose content reaches 55.46%, is potential novel high-quality textile raw material.Existing research about light leaf paper mulberry at present both at home and abroad mainly concentrates on plantation, pulping and paper-making is processed, and light leaf paper mulberry is still belonged to blank as the developmental research of a kind of textile fabric and goods.
Exploitation light leaf paper mulberry fiber both can enrich the kind of natural fabric, alleviated environmental burden, can also bring extra income to the peasant, and therefore, exploitation light leaf paper mulberry fiber can make co-benefit in many ways, and light leaf paper mulberry fiber has vast potential for future development.
Also do not have at present ripe light leaf paper mulberry fiber preparation technique open, adopt which kind of technology to produce broussonetia fibre for weaving, this is the technical problem that needs to be resolved hurrily at present.
Summary of the invention
The objective of the invention is that research field at present light leaf paper mulberry only limits to plant, the present situation of pulping and paper-making, exploitation has the more light leaf paper mulberry fiber of the weaving purposes of high added value, but a kind of preparation method of simple and effective suitability for industrialized production is provided.
The objective of the invention is to be achieved through the following technical solutions: a kind of preparation method of broussonetia fibre for weaving is characterized in that: the reparation technology flow process is: light leaf paper mulberry → preimpregnation enzyme → washing → alkali lye kiering → washing → alkali lye kiering again → washing → beat fibre → pickling → wash → dewater → shake up → oil supply → dewater → shake up → drying → colour prime white light leaf paper mulberry fiber;
Main technologic parameters is as follows:
(1) preimpregnation enzyme: through the preimpregnation pectase liquid, the light leaf paper mulberry fiber of producing is soft, loose, cohesive force is strong with light leaf paper mulberry, and spinning performance is good.Enzyme dosage is that the light leaf paper mulberry raw material of 2-5% is heavy, and temperature is 50-55 ℃, soaks 2-4 hour enzyme time, bath raio 1: 8-15;
(2) washing:, with 60 ℃ of-70 ℃ of water flushings, dissolved matter on the fiber and residual enzyme liquid are removed again earlier with normal-temperature water flushing light leaf paper mulberry fiber 3-5 minute, wash to the pH value be 6.5-7.5;
(3) alkali lye kiering: the alkali lye kiering is that light leaf paper mulberry fiber is produced topmost technical process in the engineering, and the various colloid compositions in the light leaf paper mulberry are mostly removed in this operation; Process conditions are: NaOH 5.0-10.5g/L, and auxiliary agent sodium phosphate trimer consumption is the 2%-3% of total solution weight, 100 ℃ boil and boil, and 1-2 hour, bath raio 1: 18-25;
(4) beat fibre: though light leaf paper mulberry colloid after soda boiling is easy to remove, but still have major part to be bonded on the fiber, the hydro-peening effect that utilizes wooden stick or mechanical mallet to hit with waterpower can make fiber looser, pure white the removings such as colloid that destroyed but still stick to by alkali lye on the fiber.
(5) pickling: the pickling residual alkali lye on the light leaf paper mulberry fiber that can neutralize, improve the whiteness of fiber.The acid cleaning process parameter is: H
2SO
41.0-1.5g/L, bath raio: 1: 18-25, normal temperature, the pickling time is 2-3 minute.
(6) oil supply: amido organosilicon softener consumption 4-6ml/L, bath raio 1: 10-20,40-50 ℃, 50-70 minute.
Increase bleaching process before the pickling in above-mentioned reparation technology flow process, after bleaching process is handled, can make light leaf paper mulberry fiber loose, soft, pure white, improve the surface state of fiber, improve its absorption property and wettability, and further reduce the residual gum content of fiber, spinned at last, weave, the white light leaf paper mulberry fiber of clothes processing usefulness.
In above-mentioned reparation technology flow process bleaching process, adopt the technological parameter of hypochlorite bleaching liquor to be: effective chlorine density 0.5-1.5g/L, normal temperature, processing time 1-3 minute, the pH value of bleaching liquor was 6.5-7.5.
The present invention compared with prior art has many advantages and good effect:
1, method of the present invention can become light leaf paper mulberry the more textile fiber of high added value, can enrich the kind of natural fabric, alleviates environmental burden, can also bring extra income to the peasant, therefore, exploitation light leaf paper mulberry fiber can make co-benefit in many ways, and light leaf paper mulberry fiber has vast potential for future development.
2, different because of each composition in cellulose, hemicellulose, lignin, the colloid to the stability of chemicals effects such as water, inorganic acid, alkali and oxidant.For example, hemicellulose, lignin, pectin substance, the ash composition that grades is easily dissolved by the high temperature alkaline solution effect, and cellulose then shows advantages of higher stability to the effect of alkali lye.Therefore, the method that the fiber that the present invention adopts biology, chemical process and mechanical treatment to combine is produced, but this is a kind of simple effectively method of suitability for industrialized production, and technology is reasonable, and cost is low, helps applying.
