Abstract
The invention discloses a ramie degumming boiling-out liquid, which comprises the following components in percentage by weight: 2.5%-2.6% of NaOH, 0.25%-0.3% of BT boiling-out auxiliaries, 0.09%-0.1% of sodium tripolyphosphate, 0.09%-0.1% of Na2SO3, and the balance being water according to the amount of the boiling-out liquid. When the boiling-out liquid is used for degumming ramie, cleaned ramie is added into a boiling-out pot and boiled out together with the boiling-out liquid for 3.5-4h under the pneumatic pressure of 2-2.3kg/cm<2>. The usage amount of the prepared boiling-out liquid is reduced, the selection and usage amount of the boiling-out auxiliaries are proper, and gum substances in the raw ramie can be effectively removed.
Description
Technical field
The invention belongs to the degumming technical field of flax fibre, be specifically related to a kind of China grass degumming kiering liquid.
Background technology
Ramie (Boehmeria), also known as wild flax, family fiber crops, piemarker, hemp, belongs to Rosales, Urticaceae, Section of Genus Boehmeria.In various string, the fiber quality of ramie is best, and ramee is tough and tensile, can be used for textile cloth, and the cloth of weaving out is not only attractive in appearance but also durable; Ramee tension stress intensity is very high, may be used for making parachute, linen thread, canvas etc.; After ramee soaks, intensity can increase, and has corrosion resistant, not easily mouldy characteristic, therefore may be used for making waterproof cloth, fishnet etc.
Not only containing fiber in ramie, also containing colloidal substances such as hemicellulose, pectin, lignin, together with these colloidal substances are staggered in fiber, make raw ramie can not as the raw material for spin etc., must first through degumming technology, its colloidal substance is removed, obtains the raw material of the ramie filament spinning needed for modern industrialization ramie spinning.
In prior art, coming unstuck of ramie adopts chemical method entirely to come unstuck usually.Utilize cellulose and gum components in ramie raw ramie to the difference of the stability of alkali, inorganic acid and oxidant effect to remove the glue impurity component in raw ramie, retain cellulose components, based on this principle, adopt alkaline-heating method, alkali lye mainly adopts NaOH, the consumption of NaOH and the kind of boiling-off additive and the removal of consumption to Resins of Original Hemp material have much relations, thus affect the quality of fiber.In prior art, the use amount of NaOH is comparatively large, boiling-off additive choose and use amount improper, cause the kiering time long, the fiber quality after coming unstuck is bad, and even colloidal substance is removed and totally do not waited deficiency.
Summary of the invention
The present invention is directed to above-mentioned weak point and a kind of China grass degumming kiering liquid of providing, in this kiering liquid, alkali consumption reduces, and boiling-off additive selection and application amount is appropriate, effectively can remove the colloidal substance in raw ramie.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of China grass degumming kiering liquid, the composed of the following components and percentage composition of each component is: NaOH, BT boiling-off additive, sodium phosphate trimer, Na
2sO
3, NaOH, BT boiling-off additive, sodium phosphate trimer, Na
2sO
3addition is respectively 2.5%-2.6%, 0.25%-0.3%, 0.09%-0.1%, 0.09%-0.1% of kiering liquid, and all the other are water.
Further, when described kiering liquid comes unstuck to ramie, the fiber crops material also thoroughly washed by pre-sour operation is put into bucking kier kiering together with kiering liquid, and the kiering time is 3.5-4h, and air pressure is 2-2.3kg/cm
2.
A kind of China grass degumming kiering liquid provided by the invention, has following beneficial effect:
(1) alkali lye that uses of the present invention and boiling-off additive and other additives according to a certain ratio relation be mixed with kiering liquid and come unstuck, shorten the kiering time, decrease alkali charge, kiering time shorten 1h, alkali charge decreases 4%.
(2) the kiering liquid caustic soda consumption that prepared by the present invention reduces, and boiling-off additive selection and application amount is appropriate, effectively can remove the colloidal substance in raw ramie.
Detailed description of the invention
Embodiment
The kiering liquid using the present invention to prepare comes unstuck to ramie, comprises the following steps:
(1) ramie raw ramie is placed in softener and carries out mechanical treatment, through soft bundle and removal of impurities, make the deliquescing of ramie raw ramie be bar web-like, become softening, this process can remove unnecessary foreign material, is convenient to fill cage, shorten the dress cage time, the dress fiber crops amount of every cage can also be increased simultaneously;
(2) steep in advance: softening binding is loaded numb cage, every cage mounted 550kg, employing concentration is that the pre-acid waste liquid of 0.8g/L soaks softening, and bath raio is that 1:10 soaks by the weight ratio of softening and pre-acid waste liquid, and soaking temperature is 25-40 DEG C, soak time is 10h, this process adopts used pre-acid waste liquid to soak softening, under the relatively mild condition of acidity, can remove part colloidal substance, again pre-acid waste liquid is recycled, saved cost;
(3) acid in advance: soak with the sulfuric acid that concentration is 2-2.5g/L the fiber crops material steeped in advance; bath raio is that 1:10 soaks by the weight ratio of softening and sulfuric acid, and soaking temperature is 25-40 DEG C, and soak time is 10-12h; this process can remove portion colloidal substance, thus also can shorten the kiering time below;
(4) clean: rinse the fiber crops material after pre-acid with clear water, remove glue impurity, until the water after rinsing is neutral, then drain the moisture on fiber crops material;
(5) one boil: by NaOH, BT boiling-off additive, sodium phosphate trimer, Na
2sO
3add bucking kier with water, mixing, is mixed with kiering liquid 5500kg, NaOH, BT boiling-off additive, sodium phosphate trimer, Na
