Description
Technical field
The invention belongs to China grass degumming field, be specifically related to a kind of intelligent china grass degumming process.
Background technology
Boehmeria (Boehmerianivea) is Urticaceae perennial root, for herbaceos perennial, original China.China's Boehmeria yield accounts for the 90% of whole world Boehmeria yield, and containing the fiber accounting for Boehmeria weight 70% in Boehmeria, its fiber length, intensity are big, are the important source material in textile industry.In various Plant fiber, Ramie Fiber Quality is best.Ramee is unique in flaxen fiber to exist with ultimate fibre state, and ramee length is long, good springiness, and ultimate fibre length is up to 600MM, and tough and tensile, is rich in gloss, bright, it is not easy to fade.Pure spin or blending becomes various thickness cloth, not only attractive in appearance but also durable.The tension stress intensity of ramee is higher 8-9 times than Cotton Gossypii, it is possible to does aeroplane fabric, the raw material of parachute and manufactures the various ropes such as canvas, the rope of aviation, grenade bracing wire, linen thread.Ramee is when soaking, and intensity increases especially, absorbs and disperses moisture fast, and have corrosion resistant, not easily mouldy characteristic, is the good material manufacturing waterproof cloth, fishnet etc..Ramee heat radiation is also fast, it is not easy to conducts electricity, therefore, it can do the liner of tire, the foreskin of electric wire, the transmission band etc. of machine.Boehmeria chopped fiber can be the raw material of fine paper, gunpowder, artificial silk etc., again can weavening carpet, gunnysack etc..
The physical property of ramee, pliability are to turn the performance such as bent different with other fiber, general content of cellulose is 65-75%, half fiber content 14-16%, pectin 4-5%, water-soluble substances 4-8%, adipocere paper 0.5-1.0%, ash 2-5%, due to the special character of Boehmeria, determine its processing technique and other fiber distinct.
The keen-witted and capable Taro Aso's processing technique of traditional banding has reached 17 procedures, and technological process is long, and production capacity is undesirable, and the mode of production is semi-hand, the semi-mechanization mode of production, and product appropriation of labour power per ton is up to more than hundred people.Originally straight fiber is broken up in flax stamping device, is then subjected to the acutely thin pin of fibre separating machine and steel bar machine.Making to exist in the fiber of combing many Fried Glutinous Rice Balls with Sesame and undercoat, thus the row yielding of degumming and combing only has 56% and 46% respectively, inefficiency, labor productivity is relatively low, causes bigger labour force and consumes, and the processing cost of ramie stripes per ton is more than cotton fine twice.
Domestic more enterprise still adopts traditional chemical steaming or bioanalysis production technology, there is many deficiencies, China fiber crops industrial market seriously delayed, also result in the decline year by year of domestic plantation fiber crops yield, Hunan is Boehmeria main product ground, the cultivated area of peak period breaks through 2,000,000 mu, but taper to now 20-30 ten thousand mu, it is down to current 5-6 unit/kg by original higher price 8-10 unit/kg, raw material economics is caused to be worth on the low side, and the production technology fallen behind also is the major reason that constraints on fiber fiber crops production capacity does not increase, therefore research and development degummed ramie short route, automatization, serialization, zero-emission, high efficiency production and processing technology is urgent problem in current fiber crops industrial chain.
Summary of the invention
