Abstract
The invention provides a fluorescence processing method for preparing hemp fibers. The method comprises the following steps: putting raw hemps in water to be soaked at normal temperature for three and a half hours; putting proper amount of water in a steamer and putting the soaked raw hemps when the water is heated to 85-100 DEG C, adding degummed liquid medicine when the water temperature is 150 DEG C, continuously cooking the raw hemps for 40 minutes and reducing the water temperature to 90 DEG C after cooking; heating the water to 120-130 DEG C and then reducing the temperature to 90 DEG C after cooking for 15 minutes; heating the water to 100-110 DEG C and reducing the temperature to 90 DEG C after cooking for 10 minutes; putting the raw hemps cooked for the first time after the water in the steamer is heated to 75-85 DEG C, adding the degummed liquid medicine when the water temperature is 130 DEG C, continuously cooking the raw hemps for 40 minutes and reducing the water temperature to 90 DEG C after cooking; and heating the water to 100-110 DEG C, then reducing the temperature to 90 DEG C after cooking for 15 minutes and repeating the steps twice. The method has the beneficial effects that as the cooking process is short, the fibers are integral, can not be damaged, are complete in pectin removal, can be directly woven, without being spun, and have good fluorescent effects; the hemp fibers are slightly damaged; as the integrity of fibers is retained, the properties of the fibers are better than the properties of damaged hemp fibers; and the whole process time is greatly shortened, thus greatly improving the production efficiency.
Description
Technical field
The present invention relates to and relate to flax fibre production technical field, particularly relate to a kind of china-hemp fibers and produce fluorescence processing method.
Background technology
Fiber crops are the fibers obtained from various fibre of flax for textile material, comprise the bast fiber of annual or perennial herb dicotyledon cortex and monocotyledonous leaf fibre.Fiber crops mainly contain ramie, jute, piemarker, Chinese fiber crops, hemp, flax, bluish dogbane and gombo hemp etc.Be particularly suitable for that beriberi, pin are smelly, body odour personage uses flax fibre fabric, the advantage that flax fibre has other fibers to hardly match: there is good moisture absorption and fall apart wet with ventilative function, the features such as heat transfer heat conduction is fast, nice and cool well-pressed, perspire not next to the skin, quality light, powerful large, Vermins-proof mildew-proof, electrostatic are few, fabric not easily pollutes, the excretion of soft generous, rough, the suitable human body skin of tone and secretion.Show after deliberation, in numerous textile fabrics, flax fibre is the natural fabric of most potential function.
The method of current acquisition flax fibre has retted fibre, chemical treatment two kinds of methods, wherein the fibre separation index of retted fibre is minimum, process time is long, chemically treated fibre separation index is maximum, but also larger to the damage of linen fibre, and overall flax fibre can be destroyed in two kinds of procedures, form short fiber, could use after needing to weave to cotton mill, the performance that so not only have impact on flax fibre too increases the program of technique, makes processing cost also significantly increase.
Summary of the invention
The object of this invention is to provide a kind of china-hemp fibers and produce fluorescence processing method, its fiber is complete, can not be destroyed, and pectin is removed completely, without the need to spinning, can directly weave, and the manufacture being applicable to high-grade gunny products uses.
In order to solve the problem existing for background technology, by the following technical solutions, it comprises the following steps the inventive method:
Step one: soak: raw ramie is put into water and carry out soak at room temperature, the time is three and a half hours;
Step 2: once boiling:
1, get out steamer, in steamer, put into appropriate water;
2, etc. put into the raw ramie after immersion when water burns 85 DEG C-100 DEG C in steamer, then add the liquid medicine that comes unstuck when the water temperature of 150 DEG C, and continue boiling 40 minutes, after boiling, water temperature is down to 90 DEG C;
3, then by water secondary temperature elevation to 120 DEG C-130 DEG C, boiling is cooled to 90 DEG C after 15 minutes again;
4 and then water is warming up to 100 DEG C-110 DEG C three times, boiling was cooled to 90 DEG C after 10 minutes;
5, open steamer pot cover and be oxidized 30 minutes, then the raw ramie after boiling is put into cold water soak 1.5-2.5 hour;
Step 3: secondary boiled:
1, again water temperature in steamer is burnt after 75 DEG C-85 DEG C, put into the raw ramie after once boiling, then add when the water temperature of 130 DEG C the liquid medicine that comes unstuck, and continue boiling 40 minutes, after boiling, water temperature is down to 90 DEG C;
2, then by water secondary temperature elevation to 100 DEG C-110 DEG C, boiling is cooled to 90 DEG C after 15 minutes again;
3 and then water is warming up to 100 DEG C-110 DEG C three times, boiling was cooled to 90 DEG C after 10 minutes;
4, open pot cover and be oxidized 30 minutes, namely become flax fibre, then flax fibre is pulled out and put into cold water soak 1.5-2.5 hour;
Step 4: fluorescence:
1, the flax fibre that cold water soak is crossed is dried;
2, prepare container again and add suitable quantity of water, and add fluorescent liquid by during water temp. heating to 75 DEG C-80 DEG C, stir adding fluorescent liquid, solution pH value is no more than 8 simultaneously;
3, the flax fibre after drying is put into solution to soak, take out after soak time is no more than 5 minutes.
The china-hemp fibers that the inventive method is produced, the digestion process time is short, and therefore fiber is complete, can not be destroyed, pectin is removed completely, without the need to spinning, can directly weave, fluorescent effect is good, little to the damage of flax fibre, because it has possessed the globality of fiber, the flax fibre after its Performance Ratio destroys is better, the whole process time shortens greatly, substantially increases production efficiency.
