Description
Technical field
The present invention relates to field of textiles, a kind of Boehmeria is for spinning the chemical degumming technique of thick special yarn.
Background technology
Boehmeria is the national treasure of China, is our precious legacy, owing to ramee has strength height, antibiotic property
By force, absorb and to distribute moisture fast, the advantage such as perspire the most next to the skin.Before more than 6000 years, our people begins to
Ramee is utilized to make clothing.Over nearly more than 100 years, Cotton Gossypii achieves machinery along with the process of western industrial
Metaplasia is produced, and Boehmeria but can only rely on manual production.I crosses and falls behind situation in the 60-70 age to change this,
Organize research of technique, used other textile production process and the equipment such as Corchorus olitorius L., Pilus Caprae seu Ovis, silk spinning, piece together
Achieve Boehmeria semi-hand, semimechanized production.Owing to this technique and equipment are not according to Boehmeria self
Processing feature and design, the most not only technological process is sung, and degumming combing has reached 32 procedures, produce
Efficiency is low, and a people can only produce about 7 kilograms ramie stripes, and poor product quality, particularly flax stamping device for one day,
Originally the most straight fiber is become a pile tangled skein of jute, then through opener, the strong combing of steel wire producing machine card wire,
Long fibre is combed into chopped fiber, also been produced substantial amounts of cast tow and fiber crops knot, and therefore, the row yielding of degumming only has 60%,
Production cost is high, and the production cost of ramie stripes per ton is more than a times of Cotton Gossypii processing cost, the production of this backwardness
Technique is so far over more than 40 year, and the biggest change, the Boehmeria production making China is plummeted, now also
There is the danger cleaned out completely.Boehmeria is the distinctive kind of China, is referred to as China's grass, is mainly distributed on
Hubei, Hunan, Jiangxi, Sichuan etc. save, and total output accounts for the 90% of the world.We are only utilized by reinforcement,
The distinctive fabric of these China just can be made to become more valuable thing.
Owing to flaxen fiber containing a large amount of colloids, it is necessary to through degumming, the glue of wherein most is removed, Cai Nengzuo
Using for textile material, the scouring processes of flaxen fiber is the process of exquisite cellulose in fact, mainly has both sides
Requirement, on the one hand sloughs the colloid in raw ramie so that it is meet the prescription of Textile Engineering, on the other hand requirement
Reduce the damage to flaxen fiber as far as possible, the chemical method that many employings of Degumming Procedures in current industry are common, this
Although method processing cost is relatively low, but the damage to flaxen fiber is relatively big, although the product of production substantially meets row
Industry standard, but ramie product high-quality, high quality standards cannot be produced, and bacterial degumming method, although
The product that quality is higher can be produced, but owing to the process-cycle is long, relatively costly, it is not suitable for producing in enormous quantities
Use.
Summary of the invention
Goal of the invention: the invention aims to solve the deficiencies in the prior art, it is provided that a kind of Boehmeria is used for spinning
