Abstract
The invention discloses a kind of method of from cannabis plants, extracting fiber. this method is removed the part colloid with the biological degumming method earlier, make hemp epidermis and fiber separation, press spinning process length requirement cut staple again, remove epidermis, impurity with the method for machinery then, remove colloid with chemical method again, make fiber separation, thereby extract fiber finer, whiteness is good, brute force is high, be fit to the high-quality hemp of multiple spinning equipment.
Description
The present invention relates to a kind of extracting method of hemp.
Existing hemp extracting method has two kinds basically: a kind of is by soaking fermentation, and promptly the method for biological degumming is extracted hemp; Another kind is to be the chemical degumming law extraction fiber at center with the caustic soda boiling-off.The fiber that preceding a kind of method obtains is thicker, the multiple spinning equipment spinning of incompatibility; A kind of method in back, hemp is after soda boiling, and not diffluent numb epidermis and fiber separation are clipped in the middle of the fiber, wash not easy-clear with water, make troubles for follow-up spinning.
Task of the present invention provides a kind of spinning equipment spinning that can make fiber adapt to multiple spinning process length, as cotton, middle length, the spinning of wool type spinning equipment; And can reduce and contain numb epidermis in the fiber, the hemp extracting method of impurity level.
Task of the present invention is finished as follows: remove the part colloid with the biological degumming method earlier; Make hemp epidermis and fiber separation, after drying or drying, press the desired spinning process length of spinning equipment cut staple again, the shearing length of fiber is longer 10～20 millimeters than spinning process length, remove numb epidermis, impurity with the machinery that removes fiber impurity then, remove colloid with chemical degumming law again, make fiber separation, the last oil of stain again, oven dry have just obtained being fit to the hemp of multiple spinning equipment spinning.
Task of the present invention also can be finished as follows: earlier the numb skin that peels on the big waste of flax stem is cut off by the spinning process length of spinning equipment requirement, shearing length is longer 10～20 millimeters than spinning process length, remove the part colloid with the biological degumming method again, make hemp epidermis and fiber separation, after drying or drying, remove numb epidermis, impurity with the machinery that removes fiber impurity again, remove colloid with chemical degumming law again, make fiber separation, stain is oily more at last, and dehydration, oven dry have just obtained being fit to the hemp of multiple spinning equipment spinning.
Below the present invention is described in further detail:
1. the water of the numb skin that peels on the big waste of flax stem being put into 25 ℃～45 ℃ soaked 48～60 hours, handled 10～30 minutes under 70 ℃～90 ℃ temperature again, then it was dried or dried.2. use the softening mechanical degummed ramie softening, numb epidermis and fibre bundle are separated from each other, and remove part fiber crops epidermis, impurity, softening machinery adopts many form effects to roller pressure stone roller better; 3. soft good fiber crops are cut off by the technology length requirement that is suitable for spinning equipment, shearing length is longer 10～20 millimeters than technology length.Spin on cotton spinning apparatus, shearing length is 35～58 millimeters; Spin on medium long equipment, shearing length is 60～95 millimeters; Spin on wool spinning equipment, shearing length is 100～130 millimeters.4. remove most of numb epidermis and the impurity that contains in the fiber with removing fiber impurity machinery, removal of impurities machinery can adopt multiple-roll formula or porcupine hired roughneck formula or kirschner beater formula removal of impurities machinery, and wherein multiple-roll formula removal of impurities mechanic effect is preferable; 5. containing NaOH 15～20 grams per liters; Tertiary sodium phosphate or sodium phosphate trimer or the relative fibre weight of tetrasodium pyrophosphate 4～5%() sodium soap 3%, ten eight carbon hydroxyl unsaturated fat acid sodium-salt sulfuric ester 3%, boiled 60～120 minutes in the solution of bath raio 1: 10～15; 6. the residual waste liquid of water flush away, impurity, numb epidermis; 7. normal temperature was bleached 5～10 minutes in the solution of clorox 2～3 grams per liters (chlorinty) bath raio 1: 10～15; 8. at sulfur acid 3～4 grams per liters, the normal temperature bleaching is 5～10 minutes in the solution of bath raio 1: 10～15; 9. normal-temperature water flush away residual acid; 10. at oil emulsion 4 grams per liters, to soak 60～120 minutes in the solution that 1: 10 temperature of bath raio is 60 ℃～80 ℃, the fiber oil content is controlled at 1～2.5%; 12. dehydration, 13. oven dry.
Earlier press spinning process length requirement cut staple, carry out above-mentioned same biological degumming again, machinery also can be finished task of the present invention except that processing such as epidermis, chemical Degummings.
The present invention removes biological degumming, machinery numb epidermis, impurity and chemical Degumming three and organically combines, and has solved the hemp quality and the relatively poor problem of adaptability that merely obtain with biological degumming or chemical Degumming for a long time.Can extract fiber finer with this method, whiteness is good, intensity is high, the high-quality hemp of suitable multiple spinning equipment.
Embodiment 1:
The water that numb skin is put into 35 ± 3 ℃ soaked 50 hours, putting into 90 ℃ water again handled 15 minutes, oven dry then, to behind the roller buffing machine pressure stone roller it is cut into 45 millimeters with many, remove numb epidermis with multiple-roll removal of impurities machinery again, impurity, put into then and contain NaOH 16 grams per liters, tertiary sodium phosphate 4%, sodium soap 3%, ten eight carbon hydroxyl unsaturated fat acid sodium-salt sulfuric ester 3%; boiled 90 minutes in 1: 10 the solution of bath raio; washing is then put into after the dehydration and is contained clorox 2 grams per liters, and bleaching is 6 minutes in 1: 10 the solution of bath raio; at sulfur acid 3 grams per liters; pickling is 6 minutes in 1: 10 the solution of bath raio, and washing is put into oil emulsion 4 grams per liters; bath raio 1: 10 after the dehydration again; soaked 90 minutes in the solution that temperature is 70 ± 5 ℃, dehydration at last, oven dry.
Embodiment 2:
Earlier numb skin is cut off 45 millimeters long, and then carry out biological degumming, machinery is allowanced for bark, chemical Degumming, stain wet goods are handled.Treatment process condition is identical with embodiment 1.
