Abstract
The present invention relates to a new technology for producing hemp fiber, which belongs to the technical field of hemp raw material processing. After the raw stems of hemp planted by farmers mature, the raw stems are harvested, aired, collected into factories, bound according to different diameters and stacked. The processing technology comprises the steps that the raw stems of hemp are put into a concrete basin which is heated to 32 to 35 DEG C by a boiler and a pipeline, and the temperature is kept for 70 to 75 hours; a large amount of pectic bacteria is propagated in the basin to realize biological degumming; then, the raw stems of hemp are processed by mechanical hemp extraction to obtain finished products; after being processed by carding and health preservation, the finished products are packed and warehoused. Through the technology, industrialized large-scale production can be realized, the quality of fiber is high, and high-grade yarn and cloth can be spun.
Description
The invention belongs to bast-fibre raw material machining technology.
Hemp is commonly called as hemp and little numb seed.Traditional method is still continued to use in present hemp production, be the waste of flax bundling of peasant with harvesting, put into natural bubble inner cold water and macerate system, macerate the employing of good back and manually take off fiber crops, fiber crops are criticized and have colloid and bast, must handle by secondary chemistry or biological degumming, just can become the hemp textile raw material.Because traditional natural system of macerating and manually take off fiber crops, productivity ratio is low, and is of poor quality, be difficult to batch production production, secondary degumming is handled and has been destroyed fiber quality again, increases cost simultaneously, can not spin high-quality hempen fibre, thereby limited the development of China's hemp plant husbandry and flax spinning industry.
The objective of the invention is to invent a kind of new technology for producing hemp fiber, make traditional handwork method become batch production production, dispersion processing becomes concentrates processing, and produces high-quality hemp.
The leading portion work of process implementing of the present invention is, gathers in, dries after the hemp original stem maturation of peasant planting, and concentric acquisition is to factory, divide the footpath tie up with piling in order to handling.Its machining process is:
1, biological degumming, putting in the same concrete basin through the hemp original stem at the same level of sorting, in the pond, be warmed to 32-35 ℃ by boiler and pipeline, kept 70-75 hour, a large amount of breeding pectin bacterium are come unstuck hemp original stem in the pond, fiber crops are criticized and separate with waste of flax, just can take out and dry, stacking, to be processed.
2, machinery stripping fiber crops adopt the hemp decorticator to carry out scutching, remove impurity such as waste of flax, hards and bast.
3, substandard products are picked out in finished product combing, select qualified products, and combing is neat.
4, finished product health adopts the health of current moisture regain method to make fiber reinforcement intensity.
5, packaging and warehousing.
For satisfying this technological requirement, need plant out diameter 5-7mm, the former stem of the standard of plant height 1500-1800mm.
The present invention compared with prior art, the good effect that is had is:
1, the present invention can large-scale industrialized production replace the small peasant economy mode of production traditional, that disperse, that fall behind.
2, the hemp produced of the present invention can direct spinning, and what solved produced in conventional processes macerates, takes off the shortcoming that fiber crops and secondary chemical-biological come unstuck and could spin after handling.
3, the hemp produced of the present invention, quality is good, and cost is low, can spin high-quality hemp textile.
