Abstract
The invented bamboo fibre fluffy pulp uses bleached bamboo pulp as main raw material and compounded with proper commodity wood pulp board or cotton pulp board. The making method consists of preparation of bleached bamboo pulp, mixing basic pulp, modified treatment for paper pulp and fluffy pulp making etc. four procedures. The chemical aids LS-1 is used as unwinding modifier of the basic pulp, its active component is quaternary ammonium salt the structural formula of which is R(CH3)3N]+.Cl-(R is linear alkyl> C12). The properties of fluff and saturated absorption of said product approximated or surpassed the whole wood fibre or imported fluffy pulp and is fully suitable to make toilet paper, napkin etc. wet absorption products.
Description
The invention belongs to the paper industry field, be specifically related to a kind of Time of Fluff Slurry and manufacture method thereof that is mainly bamboo fiber.
Time of Fluff Slurry is a kind of pulp goods that has specific characteristics and can require, and its major requirement is: the napping that dissociates easily, and dust will lack when the processing napping simultaneously; Pure white, soft, flexible, the good hygroscopicity, aseptic of processing back product.It is mainly used in the moisture absorption products such as operation pad that manufacturing such as sanltary towel, baby and urgent patient use with urine towel and hospital.State's external mature technology is with full wood fiber raw material production Time of Fluff Slurry, the domestic producer that does not still have the production Time of Fluff Slurry.Reported in literature about the non-wood-fiber Time of Fluff Slurry is few.According to ABCP Congr.Anual.16th/congr.Latino-Am.Cellulose Papel(sao paulo) 3rd.vol.1: 161～166(Nov.21～26,1983) to go up and introduce, Brazil once manufactured experimently Time of Fluff Slurry with sisal hemp; Again according to sobve Deriv.Cana Agucar(Rev.ICIDCA) 21, No.3: 58～62(sept-Dec.1987) go up introduction, and Spain once produced Time of Fluff Slurry on a trial basis with bagasse chemical pulp adapted softwood pulp.But their manufacturing technology details is not revealed.By retrieval, it is more to produce the patent documentation of common paper pulp with bamboo fiber; And make the patent documentation of Time of Fluff Slurry with bamboo fiber, be not reported.
The objective of the invention is to: based on the bleaching bamboo pulp of bamboo wood manufacturing, an amount of commercial wood pulp of adapted or cotton pulp are made a kind of novel Time of Fluff Slurry that is mainly bamboo fiber.
Technical conceive of the present invention is, take the proper technology measure, reduce the heteroproteose cell in the bamboo fibre and the content of fiber fines as far as possible, in pulping process, should keep single fiber intensity and raising average fiber length in the paper pulp as far as possible, reduce the bond strength of pulpboard again as far as possible, thereby overcome the defective of bamboo fiber, satisfy Time of Fluff Slurry the specification requirement of basic slurry and the quality requirement of product.
Bamboo material fibre fluff pulp of the present invention, raw materials used proportioning (percentage by weight) is: bleaching bamboo pulp 70～80, commercial wood pulp plate or cotton starch plate 20～30.
Describe bamboo material fibre fluff pulp manufacture method of the present invention below in detail.
Bamboo material fibre fluff pulp of the present invention, its manufacture method divide the modification processing of allotment, paper pulp of the preparation of bleaching bamboo pulp, basic slurry and Time of Fluff Slurry four technical process of manufacturing paper with pulp to finish.
One, the preparation of bleaching bamboo pulp:
With length is clean old, the tender bamboo chip of 25 ± 5mm, by 1: the 1(weight) accent is mixed even, adopt traditional kraft cooking, remove the black liquor that contains impurity such as lignin sodium salt, dehydration penta candy, pectin and silicon in the bamboo pulp, making hardness is 10～12(permanganate number) thick slurry; Adopting C-E-H(then is chlorination-alkali treatment-hypochlorite) tri-stage bleaching technology, remove lignin and pigment, the purifying bamboo pulp fiber makes the bamboo pulp whiteness reach 78% at least, and the contents of residual chlorine in the bamboo pulp is reduced to below the 0.007g/L; Adopt the sieve bend of 40 meshes that most of heteroproteose cell and fiber fines in the bamboo pulp are screened out at last, to improve the average length of fiber, the dust when reducing the processing napping.To send into the pond of sizing mixing to be deployed for Zhi Bei bleaching bamboo pulp like this.
Two, the allotment of basic slurry:
Commercial wood pulp plate or cotton starch plate are pressed the raw materials used proportioning 20～30%(of product heavily) consumption, be that 3～4%(is heavy earlier by the abundant size degradation of waterpower disintegrator) paper pulp of concentration, sieve bend with 40 meshes is concentrated into 4～5%(heavily again) concentration, heavy with the raw materials used proportioning 70～80%(of product in the pond of sizing mixing at last) the bleaching bamboo pulp of consumption mixes, and is deployed into basic slurry.
Three, the modification of paper pulp is handled:
Because paper pulp in the process of dehydrating, can produce a kind of very big gravitation between the cellulosic adjacent hydroxyl, makes the hydroxyl on the cellulose key progressively close, forms hydrogen bond at last, and has strengthened the adhesion between the fiber; In addition, because the content of heteroproteose cell and fiber fines is higher than wood fiber raw material far away in the bamboo fiber raw material, though remove through screening in pulping process, remaining quantity is still higher, and pulpboard is hardened.Like this, certainly will cause back processing to be difficult for the disassociation napping.Therefore, must carry out modification to basic slurry handles.In basic slurry, add a kind of chemical assistant (abbreviation debonding agent) with Xie Jian effect, can between fiber, form very thin one deck separation layer, destroy formation and the softening heteroproteose cell and the fiber fines of hydrogen bond, adhesion between the fiber is reduced significantly, reduce the pulpboard bond strength thereby reach chemical modification, help the purpose of back handling ease disassociation napping.
Chemical assistant with Xie Jian effect is more, and cationic surfactant generally commonly used is prepared.But at the product of the present invention that is mainly bamboo fiber, satisfy the performance requirement of Time of Fluff Slurry comprehensively, must carry out strict screening debonding agent.Through repetition test, the present invention filters out the commercially available chemical assistant of commodity LS-1 by name, as basic slurry separate key modifier, its active component is that structural formula is [R(CH

12Straight chained alkyl) quaternary ammonium salt.Result of use shows that it not only separates key and bating effect is good, and does not influence the water imbibition of Time of Fluff Slurry, has also further improved the whiteness of Time of Fluff Slurry.
Modification processing method is: use 45～65 kilograms of commercially available chemical assistant LS-1 with basic slurry per ton, it is heavy to be diluted with water to 4～6%(earlier), 80 ± 5 ℃ of emulsifications, add to then in the condiment pond that basic slurry is housed, mix with basic slurry, slaking is at least 1 hour under natural temperature.
Four, Time of Fluff Slurry is manufactured paper with pulp:
The short fourdrinier wire multi-cylinder of employing board machine is manufactured paper with pulp to the slurry of handling through modification, and the speed of a motor vehicle is controlled at 10～12m/min, becomes paper moisture content to be controlled at 7 ± 2%(and weighs).
Adopt the inventive method, based on bleaching bamboo pulp, product-bamboo material fibre fluff pulp of the present invention that an amount of commercial wood pulp of adapted or cotton pulp are made, its technical indicator reaches the heavy 505-85 target level of product quality of river Q/, wherein quantitative 700 ± 50g/m fully
