Abstract
The invention relates to a base paper preparation technology for textile paper yarn, which is characterized in that: the water-soluble PVA synthetic fiber is soaked in water; the bacterial cellulose membrane is soaked in NaOH solution; and then the wood pulp fiber is untwined and cut off by Valley pulping machine; after that, the wood pulp fiber is mixed with the pre-processed water-soluble PVA synthetic fiber; and the seminal plasma is implemented in a PFI pulping machine; finally, the mixer is added with bacterial fiber, PEO, CMC and PAE evenly, and then is passed through a flow system, thereby the paper making is in the conventional way. The base paper is made by adopting non-plant fiber, namely bacterial fiber to be mixed with water-soluble PVA synthetic fiber and wood pulp plant fiber pro rata. Various fibers can be implemented with different pulping treatments by adopting the method of pulping so as to improve the making performance of fiber and to enhance the bonding force among the fibers; and the physical strength of the base paper can be improved greatly through the synergistic effect of the chemical additives during the process of making.
Description
Technical field
The invention belongs to the crossing domain of textile industry and paper industry, be specifically related to a kind of preparation technology of base paper of paper yarn for textile.
Background technology
The paper yarn body paper is a fiber product made of paper, be that string with safety and environmental protection and good toughness is a main raw material, production and processing is the paper paper slip through specified conditions, and paper slip is through dyeing, and processing technology such as sth. made by twisting, form the paper yarn that thickness does not wait, successfully be used to produce textiles.
At present, the product of domestic market paper yarn is mainly used in the colored technology weave paper of the summer hat, fashionable dress bag, disposable slippers, tatami, healthy seat etc. of the various styles of braiding, and spinning paper carries products such as paper pigtail, sudd bag, colorful rope.Be used to produce the product of weavings such as wet towel, high-grade T-shirt because of big, the with high content of technology domestic correlative study report of not seeing of production difficulty.
The instructions for use of paper yarn body paper has determined its quality requirement, the not only quantitatively low (16g/m of body paper
2About), and because the back of manufacturing paper with pulp is cutting into serial in a narrow margin obbbin, is being rolled in the process of paper yarn, and paper slip such as is stretched, reverses at the effect of composite force, this just requires body paper should have even tissue, dry strength height, characteristics that percentage elongation is big; Paper yarn also will be stood the effect of waterpower simultaneously, and anti-washing by rubbing with the hands promptly also will have higher wet strength; When guaranteeing into paper dry strength and wet strength, require to have preferable water imbibition and flexibility again.
Summary of the invention
The object of the present invention is to provide a kind of not only preparation technology simple, and when satisfying the paper strength performance, can give the preparation technology of the base paper of paper yarn for textile of the better environmental-protecting performance of paper again.
For achieving the above object, the technical solution used in the present invention is: at first the water-solubility PVA synthetic fiber with 3-4mm are incubated 15min~20min under 50 ℃~60 ℃ water temperature; Then bacterial cellulose wet-coating is soaked in 80 ℃ the NaOH solution of 0.1mol/L and is incubated 2h, the water flushing is discongested at the standing paste sample to neutral back and is discongested 8000 in the device and change~12000 and change; Be that 2% wood pulp fibre is discongested cut-out with the Valley beater again with mass concentration, 35 ° of SR~45 ° SR of control beating degree, weight in wet base 16g~20g, then with its with through pretreated water-solubility PVA synthetic fiber with 97~98: 3~2 mass ratio mixes, in the PFI fiberizer, carry out refining, the making beating gap is 0.3mm~0.5mm, and refining pulp quality concentration is 8%~10%, and the pulping beating degree is 60 ° of SR~70 ° SR; The bacterial fibers that adds synthetic fiber and wood pulp fibre mixture quality 0.05%~0.07% at last, the PEO that adds total mixture quality 0.05%~0.09%, 0.1%~0.5% CMC, 1.6%~2.0% PAE, mix, the mass concentration of regulating slurry is 0.4%~0.8%, through approach system, under 70 ℃~80 ℃ baking temperature, adopt usual manner to manufacture paper with pulp into paper.
It is that bacterial fibers, water-solubility PVA fiber mix in proportion with the wood pulp string and manufacture paper with pulp that the present invention adopts non-plant fibre.The poor-performing because non-plant fibre is manufactured paper with pulp, the quantitatively lower again (16g/m of body paper
2About), so paper strength is undesirable; And at first adopting methods of beating that various fibers have been carried out different making beating, the present invention handles the performance of manufacturing paper with pulp that improves fiber, adhesion between fortifying fibre; And the cooperative effect by auxiliary agent in the process of manufacturing paper with pulp, the physical strength of body paper is improved greatly.Its dried strong tensile index of product that obtains by preparation technology of the present invention is 71.10Nm/g, and wet strong tensile index is 30.03N.m.g
-1, tear index is 8.01mN.m
2.g-1, folding strength is 460 times, and percentage elongation is 2.46%.
