Abstract
The invention discloses a high-strength viscose fiber and a production method thereof, which are characterized in that the viscose fiber is formed by mixing bacterial cellulose and viscose spinning solution, wherein the content of the bacterial cellulose in the viscose fiber is 1 to 10 percent. The production method comprises the following steps: the flake bacterial cellulose is pre-processed, and then the flake bacterial cellulose after the preprocessing is smashed with a ball milling method to obtain a micro nano-grade bacterial cellulose powder; the bacterial cellulose powder is added into the viscose spinning solution to be uniformly scattered and defoamed to obtain a spinning solution; and the spinning solution is made into a high-strength viscose fiber. The content of the bacterial cellulose in the viscose fiber is 1 to 10 percent. The viscose fiber which is prepared with the production method has high strength, small shrinkage and good elasticity, can be blended and interwoven with cotton, wool and other synthesized fibers to be used for the fields such as top-grade costume fabric and industrial textiles, and the like.
Description
Technical field
The present invention relates to the production technical field of viscose, relate in particular to a kind of polynosic fibre, with and production method.
Background technology
Viscose is an artificial fibre of realizing suitability for industrialized production the earliest, and as far back as 19 end of the centurys, three Britain scientist Cross, Bevan and Beadle have just invented the method that makes cellulose xanthate, and have applied for the patent of cellulose viscose manufacturing technique.Over more than 100 year, viscose is because its comfortable wearability receives consumer's favor for a long time always, and its output also is maximum in the cellulose fibre always, compares with synthetic fiber, and the advantage of viscose is mainly reflected in three aspects:
1 raw material sources are extensive, belong to renewable resource.Viscose is to be the artificial fibre of main material production with the native cellulose, and cotton linter, timber, bamboo, reed etc. all can be extracted cellulosic material.With respect to being the synthetic fiber of raw material with the oil, the resource of viscose can be described as inexhaustible.Along with the shortage of petroleum resources and constantly riseing of price, the advantage of viscose further manifests.
2 product wearability are good.The chemical constitution of viscose is identical with native cellulose fibre, has moisture absorption, ventilative, softness, easy dyeing, series of advantages such as antistatic, and it is worn as snug as a bug in a rug.And the spinnability of viscose glue is also very excellent, can be with cotton, hair and other synthetic fiber blending, interweave, be used for every field such as clothes, decoration, health care and industry articles for use.
3 viscoses ability natural degradation, itself is nontoxic, and discarded object is very easily handled, and does not pollute the environment.And synthetic fiber can discharge poisonous material in degraded, decomposable process, and reclaim difficulty, are prone to cause " secondary pollution ".
Though viscose has above-mentioned series of advantages, its shortcoming is also obvious: the brute force of viscose is lower, and is especially wet powerful relatively poor, has only more than 1/2nd of dry strength, can not wash by rubbing with the hands strongly during washing, takes the life-span weak point; The washing shrinkage of viscose is high, and the outward appearance of washing back fabric is undesirable; The poor flexibility of viscose, yielding when wearing, it is grand that local arch can take place for the elbow of generation wrinkle, particularly clothes and knee position, influences the attractive in appearance of fabric.Therefore, how to utilize the production equipment and the technology of common viscose fiber, realize the industrialization production of polynosic fibre, have important social and economic benefit, help promoting the industrial upgrading of China's chemical fibre industry.
Summary of the invention
One of task of the present invention is to provide a kind of polynosic fibre.
Two of task of the present invention is to provide a kind of production method of polynosic fibre.
For realizing foregoing invention task one, its technical solution is:
A kind of polynosic fibre is mixed with rayon spinning solution and is processed viscose by bacteria cellulose, and wherein, the content of bacteria cellulose in viscose is 1%～10%.
For realizing foregoing invention task two, its technical solution is:
A kind of production method of polynosic fibre comprises step:
A carries out preliminary treatment to the sheet bacteria cellulose, adopts ball-milling method to pulverize the bacterial cellulose powder that obtains micro/nano level then;
B adds above-mentioned bacterial cellulose powder to the also deaeration that is uniformly dispersed in the viscose spinning solution, obtains spinning solution;
C processes polynosic fibre with above-mentioned spinning solution;
Wherein, the content of bacteria cellulose in viscose is 1%～10%.
Among the above-mentioned steps a, the sheet bacteria cellulose added to carry out the activation processing certain hour in the ethylenediamine solution, wash, filter the final vacuum oven dry through washing, ethanol again, get into the ball-milling method pulverising step again; Among the above-mentioned steps c, spinning solution is squeezed in the coagulating bath through spinning head, carries out washing stretching then and handle, oven dry at last obtains above-mentioned polynosic fibre.
Comprise step among the above-mentioned steps a:
A1 is with sheet bacteria cellulose 80～100 ℃ of oven dry 1～2h in vacuum drying oven;
It is in 5%～10% the ethylenediamine solution that sheet bacteria cellulose after a2 handles step a1 adds concentration to, room temperature mechanical stir process 1.5～2h;
Sheet bacteria cellulose after a3 handles step a2 use distilled water wash earlier, uses alcohol immersion again 2～5 times, and each 10～60min filters afterwards in vacuum drying oven 80～100 ℃ and dries to constant weight.
Comprise step among the above-mentioned steps b:
B1 little by little adds bacterial cellulose powder in the viscose spinning solution under the ultrasonic wave effect, obtains the mixed solution of the two;
The mixed solution that b2 obtains step b1 is handled 30～60min under the ultrasonic wave effect, obtain finely dispersed mixed solution;
The mixed solution that b3 obtains step b2, vacuum deaerator 20～24h or discontinuous degassing 24～36h obtain above-mentioned spinning solution.
Useful technique effect of the present invention is:
1 the present invention can utilize the production equipment and the technology of common viscose fiber, has realized the suitability for industrialized production of polynosic fibre.
2 the present invention utilize bacteria cellulose degree of crystallinity high and powerful high; And the characteristic of any variation do not take place in aqueous slkali; Bacteria cellulose is processed the powder of micro/nano level; Add to again in the viscose spinning solution, thereby acquisition can be produced the spinning solution of polynosic fibre, adopt the production technology and the equipment of common viscose fiber can produce polynosic fibre.This method is simple, and operating procedure is controlled, also can adjust the content of bacteria cellulose according to the intensity of final fiber.
3 the present invention adopt ethylenediamine solution that the sheet bacteria cellulose is carried out preliminary treatment; A large amount of hydrogen bonds in the bacteria cellulose are come out; Can form stronger hydrogen bond action power with the cellulose macromolecule in the rayon spinning solution, thereby improve the intensity of viscose.
4 the present invention adopt the ultrasonic dispersing bacterial cellulose powder; Make that the distribution of bacterial cellulose powder is more even in the spinning solution; And can fully contact with the cellulose macromolecule in the viscose solution, form more hydrogen bond action power, help to improve the intensity of viscose more.
The viscose intensity that 5 the present invention produce is higher; And have excellent hygroscopicity and snugness of fit, washing shrinkage is little, good springiness; Can or interweave with cotton, hair and other synthetic fiber blending, be particularly suitable for fields such as high-grade fabric and fabrics for industrial use.
