Abstract
The present invention discloses a solvent method cellulose base fiber and method for making same. The solvent method cellulose base fiber in accordance with the present invention is prepared by adopting cotton pulp as the main raw material, adopting N-methyl morpholines oxidate as the solvent and adopting an activating enzyme as the sensitizing compound. The cellulose base fiber is detected by adopting Germanic TITK Lyocell fabric standard and the results indicate that the mechanical performances and performance property thereof entirely accord with the related regulations, the hand feeling is soft, at the same time, a great deal forest product is not required and the resource can be saved, then this is a green product and has very remarkable social and economic benefits.
Description
Technical field
The present invention relates to a kind of cellulose fiber by solvent method and preparation method thereof.
Background technology
Cellulose fiber by solvent method is called as the green fiber of 21 century, is the upgraded product of traditional viscose.The English name of cellulose fibre is Lyocell, and Chinese is a Lyocell.This fiber is main material with the wood pulps, is that solvent prepares with NMMO that compare with traditional cellulose fibre, technological process is short, and energy consumption is low, and environmental pollution is little.But,, therefore, not only need to consume a large amount of timber because the Lyocell fiber is main material with the wood pulps, and the fiber wood pulps quality that is obtained is harder, has a large amount of nodes of shearing, solvent is difficult to infiltration, and insoluble matter and particulate are more in the slurries, influence strainability and spinning properties.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of cellulose fiber by solvent method and preparation method thereof, to overcome the above-mentioned defective that prior art exists.
Cellulose fiber by solvent method of the present invention is main material, is solvent, is the activator preparation with activating enzymes that with the N-methylmorpholine oxide its parts by weight comprise with the cotton pulp dregs of rice:
1 part of the cotton pulp dregs of rice
5～7 parts of N-methylmorpholine oxides
1/210～1/230 part of activating enzymes
The said cotton pulp dregs of rice be a kind of be the product of feedstock production with the cotton linter, the preparation method of these cotton pulp dregs of rice is a kind of prior art, on the general book of teaching narration is arranged all, its weight solid content is 87～90%, though itself and wood pulps are a kind of string pulp,, the difference of essence is arranged again, its difference is, the length difference of fiber, the sugar content difference, quality is variant.
Its physical and chemical parameter can be referring to FJ517-82
The general structure of said N-methylmorpholine oxide is:
Said activating enzymes are a kind of protease, and the trade mark of producing as German BIOPRACT company is the Cellupract AL70 of IPL5B06610.
The preparation method of above-mentioned cellulose fiber by solvent method comprises the steps:
The cotton pulp dregs of rice are activated in water under the effect of activating enzymes, after squeezing in the N-methylmorpholine oxide swelling up to dissolving, swelling temperature is 50～80 ℃, swelling time is 0.25～2 hour, is 4～10 ℃ at coagulation bath temperature then, and the coagulating bath weight concentration is 15～25%, air gap is under the condition of 5～25mm, adopt dry-wet spinning, adopt conventional method to carry out post processing at last, promptly obtain the said fiber of the present invention.
Said coagulating bath is the aqueous solution of the aqueous solution or N-methylmorpholine oxide, the aqueous solution of preferred N-methylmorpholine oxide, and its weight concentration is 15～25%;
The weight consumption of water is 17～22 times of the cotton pulp dregs of rice;
Its parts by weight are:
1 part of the cotton pulp dregs of rice
5～7 parts of N-methylmorpholine oxides
1/210～1/230 part of activating enzymes.
Adopt the cellulose fiber by solvent method of method preparation of the present invention, adopt the Lyocell standard fibre of the TITK of Germany to detect, the result shows, its mechanical property and take performance complies with relevant regulations fully, and soft, simultaneously no longer need to consume a large amount of timber, can economize on resources, be a kind of green product really, has very significant social and economic benefit.
