Abstract
The invention discloses an ananas hemp chemical degumming process. The process is characterized in that: the process comprises the following steps of ananas hemp piecing out and caging, pre-pickling, boiling, washing, pickling, denaturation, acid washing, washing, lignin removal, washing, greasing and drying procedures. The boiling comprises the following steps: adding the fibril into a 30 percent mixed liquor which is prepared from liquid alkali, trisodium phosphate and water glass and has a weight 15 to 17 folds of that of the fibril, keeping the pressure of 0.1 to 0.15 MPa for 4 to 4.5 hours, and taking out the fibril and washing the fibril by water. The mixed liquor used for boiling the fibril comprises 10 to 12 g/L of the liquid alkali, 0.4 to 0.6 g/L of the trisodium phosphate and 2 to 2.5 g/L of the water glass. The liquid alkali boiling eliminates non-cellulose substances in the ananas hemp, and makes the ananas hemp have a high capillary penetration action. The fiber molecules have relatively uniform lengths; the fiber fineness is high and reaches 550 yarns; and therefore the ananas hemp is suitable for spinning.
Description
Technical field
The present invention relates to a kind of fibrillation degumming tech of textile technology Application Areas, specifically be meant a kind of chemical degumming technique for pineapple leaf fiber.
Background technology
Arghan is the fiber that extracts from pineapple leaf, belongs to the vein fiber.Relevant studies show that, after this fiber is handled through deep processing, its strength ratio cotton height, outward appearance is pure white, soft and smooth property, feel such as silk are like flax, can with natural fabric or synthetic fiber blending, fabric is printed and dyed easily, absorbing sweat is ventilative, well-pressed wrinkle resistant, the various middle and high shelves western-style clothes of suitable for making, shirt, skirt robe, necktie and various draperies etc.In addition, arghan also has good antibacterial bacteriostatic characteristic.
At present, external utilization to arghan still is in the research and development stage.In Philippine, the method that arghan is come unstuck is: fiber is placed in 0.05% wetting agent flooded 1 hour, boiled 2 hours in 5% NaOH and 0.05% sodium bisulfate then, clean with 3% acetum at last.The yarn that spins with this fiber is hard, is not suitable for textile mills' requirement, needs to adopt better softening process.
Domestic Guangxi thin,tough silk fiber crops research institute has also found out technical recipe technology such as a whole set of pineapple leaves is selected leaf, striking, come unstuck, fiber is scouringed and bleaching, and make pineapple leaves degummed ramie 160kg, test weaving goes out more than 100 meter of 100 spies/2 (50:50) pineapple fibre, cassava (silkworm) silk blending lining, but this cloth is harder, and degumming technology does not also meet the requirement that textile product is produced.China Textile University is from the nineties, also carried out arghan performance, structure, come unstuck, comparatively systematic research and exploration such as spinning, the fiber of handling is soft not enough but it comes unstuck, can only with other fiber blend, the pure yarn that can only spin 10 public that spins, also have very big gap with the requirement of public of the hemp product 20-40 of existing market demand, can not be applied to produce.
So, up to now, also do not adapt to the arghan degumming tech technology of producing both at home and abroad.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide hardness, raising fibre fineness and the pliability that can reduce arghan, thereby make it be applicable to the chemical degumming technique for pineapple leaf fiber that weaving is produced.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of chemical degumming technique for pineapple leaf fiber is characterized in that adopting the following step:
(1) fibrillation is divided the dress cage;
(2) pre-pickling: fibrillation is put into the H that concentration is 2.5～3.5g/L
2SO
4In the solution, bath raio is 1:15～17, soaks 40～50min at normal temperatures, takes out raw ramie;
(3) kiering: the concentration that fibrillation is put into 15～17 times of its weight is the mixed solution that 30% liquid caustic soda, tertiary sodium phosphate and waterglass mixed preparing form, and the 0.1～0.15MPa that keep-ups pressure, takes out the raw ramie flushing with clean water at 4～4.5 hours dwell times;
(4) pickling: fibrillation is put into the H that concentration is 2.5-3.5g/L
2SO
4In the solution, bath raio is 1:15～17, and normal temperature soaks 20min down, takes out raw ramie;
(5) sex change: the concentration that fibrillation is put into 15～17 times of its weight is 30% liquid caustic soda and the formulated mixed solution of soda ash, and soak at room temperature 10min takes out raw ramie;
(6) pickling: fibrillation is put into the H of 65～70g/L
2SO
4In the solution, rinsing to fiber yellow takes off, and turns white, and black patch can not be arranged, and takes out the raw ramie flushing with clean water;
(7) delignification: what fibrillation was put into 15～17 times of its weight is 30% hydrogen peroxide and 30% the formulated mixed solution of liquid caustic soda by concentration, and the 0.1～0.15MPa that keep-ups pressure, takes out the raw ramie flushing with clean water at 1 hour dwell time;
(8) oil supply: fibrillation soaks 30min in containing 80～100 ℃ of hot water of oil emulsion;
(9) fibrillation dewaters, trembles fiber crops, oven dry, get final product refined silk.
The content of liquid caustic soda is 10～12g/L in the used mixed solution of the described kiering operation of technology of the present invention, and the content of tertiary sodium phosphate is 0.4～0.6g/L, and the content of waterglass is 2～2.5g/L.
The content of the used liquid caustic soda of the described sex change operation of technology of the present invention is 50～55g/L, and the content of soda ash is 60～65g/L.
The content of the used hydrogen peroxide of the described delignification operation of technology of the present invention is 8～10g/L, and the content of liquid caustic soda is 3.5～4.5g/L.
The described oil emulsion content of technology of the present invention is 0.9～1.2% of fibrillation weight.
Beneficial effect of the present invention is: adopt the alkali lye kiering, can be molten except that the non-cellulose material in the arghan, and make arghan have the capillary percolation effect of height, fiber molecule length is consistent, and the fibre fineness height can reach 550, is beneficial to spinning.
