The specific embodiment
1, cotton stalk raw material preliminary working
With cotton stalk end to end section cut, intermediate host is partly put into the natural law still that comes unstuck, the two ends waste material is made cheese fuel through pulverizer, extruder.
2, cotton stalk biologically degumming bast fibers technique
(1) cotton stalk bast fiber comes unstuck naturally
Naturally come unstuck and exactly cotton stalk bast is bundled into wisp, being immersed in the sealing that pond water is housed comes unstuck in the still; bath raio 1:30; keep 16～22 ℃ of water temperatures under normal pressure, come unstuck through 18～22 days microbiological anaerobics fermentation; utilize the synergy of various microorganisms in the water, produce the enzymes such as pectase, the macromolecular compounds such as pectic substance in the cotton stalk are resolved into micromolecular compound; then cotton stalk is taken out, can strip out cotton stalk skin with cotton stalk peeling machine or manual method.
(2) the cotton stalk skin after naturally coming unstuck is peeled come.Cotton stalk xylem lease making is pulverized and is used for papermaking or viscose manufacturing; Cotton stalk skin dries, and beats with machinery and is separated into loose shape crude fibre, and this part is removed approximately 45% colloid etc. of cotton stalk bast, row yielding is about 53%, and the mud of the middle precipitation of coming unstuck can be used as farm manure and uses, and the pond water in the still that comes unstuck is reusable, the rear crude fibre color and luster that tentatively comes unstuck is dark yellow, and feel is hardened.
(3) compound biological enzyme of cotton stalk bast fiber comes unstuck
The compound biological enzyme process of coming unstuck of cotton stalk bast fiber of the present invention is, in still is come unstuck in sealing, put into through naturally coming unstuck and the cotton stalk bast of supersonic oscillations, the technological parameters such as solution temperature retention time that design adds concentration with certain 301L compound biological enzyme, pH value, comes unstuck, take full advantage of the biologically active of 301L compound biological enzyme, the colloidal complex of degraded bast fiber outer wrapping, thus make fiber separation, and the part lignin remove.Compound biological enzyme of the present invention comes unstuck process institute water for through softening pure water, prepares in the degumming water solution 301L compound bio enzyme concentration 4g/L, pH value 9, temperature retention time 10h under 50 ℃ of conditions of solution temperature.Employed solution can be after filling into the 301L compound biological enzyme Reusability, need not discharge waste water.
3, FD-ZT02 cooking additive+alkali is united and is removed lignin technology in the cotton stalk bast fiber
(1) with cotton stalk bast crude fibre behind the biological enzyme degumming through pickling, a boiling-off, washing, two boiling-offs, water washing, dehydration, oven dry, beat finely, wherein pickle bath is than being 1:28-32, pH=5; The boiling house solution of a boiling-off consists of FD-ZT02 auxiliary agent 3 g/ L, NaOH 13 g/ L, and bath raio is 1: 8-12; 100 ℃ of normal pressures, insulation 100-140 min; Secondary boiling-off boiling house solution consists of FD-ZT02 auxiliary agent 1 g/ L, NaOH 5 g/ L, bath raio 1: 8-12; 100 ℃ of normal pressures, temperature retention time 50-70min.
Because one boils FD-ZT02 assistant concentration, the NaOH concentration of boiling with two certain gradient is arranged, carry out two in available one the lean solution after boiling and boil.
(2) experiment of the cotton stalk bast fiber of the removal studied of the present invention lignin is to carry out in common textile dyeing and finishing cooking pot, and institute's water be through softening pure water, and kiering liquid can the repetitive cycling application.Crude fibre is removed after the lignin, the jaundice that becomes of the color and luster of fiber, but fiber is but very loose, and lignin removing rate reaches 72.1%, lignin average content 5.1% in the cotton stalk bast fiber behind the taking-up lignin.
The after bleaching of coming unstuck of 4 fibers reaches to oil processing
Cotton stalk bast fiber through bleaching, oil supply, naturally dry, beat fine shredding, crush cutting obtains cotton stalk bast textile technology fiber, the consisting of of bleaching liquid: H
