Liu Liyan of polytechnical university et al. utilizes the method that enzyme and chemical reagent combination degumming prepare Herba Typhae fiber；Henan Engineering College
Zhou Rong et al. the spinning pre-treating method that have studied bracteal leaf of corn fiber etc., additionally, the research to bamboo fibre is the most
And technical maturity has realized industrialization.
China's Garlic yield is the highest at present, and annual production reaches 4,000,000 tons, and in Bulbus Allii production process, a large amount of garlic sprouts leaves are taken as
Waste disposal falls.Garlic sprouts leaf is the leaf during Garlic Growth, the high cellulose in more than 35cm, garlic sprouts leaf of garlic sprouts plant
Content original text, and containing nutritional labelings such as protein, carotene, thiamine, riboflavin, acidic polysaccharoses.Peppery in garlic sprouts leaf
Element has gas of being amusing, the effect of removing food stagnancy food, also has good sterilization, bacteriostasis, can effective flu-prevention, enteritis etc. because of
The disease that environmental pollution causes.Therefore, the fiber made with garlic sprouts leaf has health care, and the most only document reports garlic sprouts
Leaf fibre produce the research with key property, i.e. use cellulase dipping garlic sprouts leaf fibre, but fiber usually time be long,
The attachment of fiber is more, and the Length Regularity of fiber is poor, and the intensity of fiber is the highest.
Summary of the invention
In order to solve above technical problem, the purpose of the present invention makes offer one intensity and elongation at break is high and fibre length is long
Garlic sprouts leaf fibre, the preparation technology of this fiber is to use compound enzyme, microwave and Cement Composite Treated by Plasma garlic sprouts leaf fibre, by three
The synergism of person, and the intensity of fiber, elongation at break and length can be improved through the specific technique that processes, and can
To shorten fiber usually time, reduce garlic sprouts leaf fibre surface attachments and improve spinnability.
For realizing the purpose of foregoing invention, the technical scheme that the present invention takes is as follows:
A kind of garlic sprouts leaf fibre, comprises the steps:
(1) pretreatment:
Pluck garlic sprouts leaf, dry through over cleaning, carry out machinery and beat remove impurity, then carry out pretreatment with Compound-acid, process time 10-30min,
Temperature 50-70 DEG C, bath raio 1:20；
(2) low-temperature plasma processes:
Pretreated garlic sprouts leaf fibre is washed 2-3 time, dries, be placed in the reative cell of plasma generator, close reative cell,
Evacuation, accesses oxygen, opens radio-frequency power supply after steady air current, and power is 300-400W, processes time 3-5min, puts
Gas, opens vacuum chamber, takes out garlic sprouts leaf fibre；
(3) microwave exposure and compound enzyme alternate treatment:
Garlic sprouts leaf fibre after being processed by low-temperature plasma is put into and is carried out microwave exposure, microwave for the first time in normal pressure microwave quick-reaction system
Power bracket is 500-800W, and the time is the 20-40 second, and temperature 60-70 DEG C then takes out, and is immersed in the first compound enzyme and processes
In liquid, the first described compound enzyme treatment fluid mainly comprise for: acid pectase, neutral cellulase, hemicellulase,
Laccase and protease, then carry out second time microwave exposure, and range of microwave power is 500-800W, and the time is the 10-20 second, temperature
Spend 60-70 DEG C, then take out, be immersed in the second compound enzyme treatment fluid, the second described compound enzyme treatment fluid mainly comprise for
Acidic cellulase and xylanase.The parameter that wherein secondary compound enzyme processes is bath raio 1:20, time 10-30min, temperature
Spend 40-44 DEG C；
(4) wash, soap, be dehydrated, shake up, oil supply, drying.
Described Compound-acid is any two kinds or combination of the above, joining of Compound-acid in citric acid, oxalic acid, malic acid, tartaric acid
Fang Wei: citric acid 2-4g/L, oxalic acid 1-2g/L, malic acid 1-2g/L, tartaric acid 1-2g/L.
Preferably, the formula of Compound-acid is: citric acid 4g/L, oxalic acid 2g/L, malic acid 1g/L, tartaric acid 1g/L.
Mainly comprising as acid pectase 1.25-2.25g/L, neutral cellulase of described the first compound enzyme treatment fluid
0.25-1.25g/L, hemicellulase 0.1-0.2g/L, laccase 0.1-0.2g/L, proteinase-10 .1-0.2g/L,
