Abstract
The present invention relates to a method for preparing medical gummed tape cotton paper, which is made of the following raw materials in the weight proportion: 20 and 40% of wood pulp, 20 and 30% of vinylon, 20 and 40% of water-soluble fiber and 10 and 20% of composite artificial fiber. The method comprises the specific process flow of the following steps: step 1. a pulping machine is used for pulping, the pulping concentration is between 2.5 and 3.0%, the pulping ampere is between 50 and 60 Ampere, and the beating time is between 15 and 20 minutes; step 2.0.1% of whitening agent and 1.5 to 2.0% of water and oil resistance agent are added in a stuff chest for about 3 hours; step 3. machine coating with PVA as coating agents is used, and the coating concentration is between 2 and 3%; step 4. baking treatment is carried out. The method has the advantages that multicomponent synthetic fibers and plant fibers are matched together, the porosity factor of products is enhanced, and the flexibility of the quality of paper is changed; because longer synthetic fibers are used, the strength of products is also improved, the means of reinforcement in pulp and coating reinforcement is used for ensuring the binding force between fibers, and therefore, the operation strength of the products is ensured.
Description
Technical field
The present invention relates to the wet nonwoven fabrics field, mainly is a kind of preparation method of medical adhesive tape cotton paper.
Background technology
The medical adhesive tape cotton paper is one of wet nonwoven fabrics series of products, is applied to the intermediate materials of medical and health industry curable product, replaces nondegradable materials such as yarn matter cloth or plastic sheeting.As the intermediate carrier of viscose glue, need have high-air-permeability, high strength, high tenacity, environment-friendly degradable is arranged, do not cause the advantage of secondary pollution.Because adopting chemical fibre is main raw material, the difficulty of manufacturing paper with pulp on general paper machine is bigger.Chemical fibre has that density is low, hydrophobicity and the characteristics of fibrillating not, easily produces problems such as fleeces is poly-, intensity difference.Succeeding in developing of it has very realistic meaning.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, and a kind of preparation method of medical adhesive tape cotton paper is provided.Use the medical adhesive tape cotton paper paper cleaning that this method is prepared, no dust reaches hygienic requirements; The papery softness, good hand touch resembles the sensation of cloth; The air permeability height, pulling force is than little in length and breadth, do not feel sad when satisfying the patient and using, and is ventilative when keeping pasting, and has good extensibility, makes patient's skin comfortable.
The technical solution adopted for the present invention to solve the technical problems.The preparation method of this medical adhesive tape cotton paper, it is made by the following weight proportion raw material, wood pulp 20～40%, polyvinyl 30～20%, water-soluble polyvinyl alcohol fibers 40～20%, terylene 10～20%; 1), adopt the beater making beating concrete technological process:: beating consistency 2.5～3.0%, making beating ampere a 50～60A, beating time 15～20 minutes; 2), in reserve pit, add brightening agent 0.1%, add water-and oil-repellent agent 1.5～2.0%, the swollen time was at 3 hours; 3), be coated with on the employing machine: the smears is PVA, coating concentration 2～3%; 4), do oven dry and handle, temperature and time is principle with the oven-dry paper.
Advantage of the present invention is: 1, handle by side wave formula long mesh paper making machine, the PRODUCTS FIELD after manufacturing paper with pulp compares near 1: 1 to tension intensity.Fiber more even to distributing in length and breadth, structure is more loose, intersects hole squarely (it is microscler that other products becomes) between fiber, the product height that air permeability is manufactured paper with pulp than other former.2, adopt multi-components synthetic fiber and string to join and copy, improved product porosity, changed the pliability of papery, more pliable and tougher than traditional product, simultaneously,, make the intensity of product also be improved owing to adopt long synthetic fiber.3, adopt the means of reinforcement and coating reinforcement in the slurry, reinforcement is by add the wet tensile strength that AKD mainly is the enhancing paper in slurry in the slurry; The coating reinforcement is to be coated with PVA to strengthen the dry tensile strength of paper at the l Water Paper page frame table, has guaranteed interfibrous adhesion, has guaranteed the working strength of product.
The specific embodiment:
Below in conjunction with embodiment the present invention is further described.
Embodiment 1: the preparation method of this medical adhesive tape cotton paper, 1), mainly may further comprise the steps: the following weight proportion raw material, wood pulp 30%, polyvinyl 30%, water-soluble polyvinyl alcohol fibers 20%, terylene 20% adopts the beater making beating: beating consistency 2.5～3.0%, making beating ampere 50～60A, beating time 15～20 minutes.
Water-soluble polyvinyl alcohol fibers (PVA) is a kind of of great value functional differential fibers.The water-solubility PVA fiber not only has desirable water solution temperature, intensity and degree of stretching, good acidproof, alkaline-resisting, dry heat resistance performance are arranged, and water-soluble back is tasteless, nontoxic, the aqueous solution is the water white transparency shape, in the short period of time can natural decomposition, environment is not produced any pollution, is hundred-percent Green Product.
Composite man-made fibre is the chemical fibre that " is glued " monofilament by two kinds of polymer.Because composition, the mechanics mechanical performance difference of two kinds of polymer as the shrinkage factor difference, so produce strong the contraction, form natural permanent curling shape.Composite fibre has the characteristics of " maximizing favourable factors and minimizing unfavourable ones ", and composite man-made fibre adopts the terylene synthetic fiber in the present embodiment, and the conformality of polyster fibre is good, and rigidity is strong, and the eye of making is adorned well-pressed, unfortunately easy dyeing not.
2), in reserve pit, adding Main Ingredients and Appearance is the fluorescent whitening agent 0.1% of talan type, adds water-and oil-repellent agent AKD (alkyl ketene dimer) 1.5～2.0%, the swollen time is about 3 hours.
3), optic vesicle foam situation, in stock tank, add 10～20ml weaving silicon defoamer.
4), be coated with on the employing machine: the smears is PVA (polyvinyl alcohol), coating concentration 2～3%; Owing to coating work is this layers of polyethylene alcohol to be arranged still by the infiltration reason on the therefore surface at paper of carrying out on the l Water Paper page or leaf, also there is certain polyvinyl alcohol page inside, so the page layering is not very directly perceived, (ambiguous says) be we can say and be divided into three layers: top layer-----polyvinyl alcohol, the mixing interlaced plies of sandwich layer-----wood pulp and chemical fibre, bottom-----polyvinyl alcohol.
5), do oven dry and handle, the drying cylinder steam pressure leaves low as far as possible, temperature and time is principle with the oven-dry paper.Be generally (drying 80 ℃ * 15 minutes)
The basic equipment that adopts: beater, storage pulp grinder, fluffer, cutting machine, side wave formula long mesh paper making machine (the stronger special fibre adaptability of manufacturing paper with pulp is arranged, and the product of being manufactured paper with pulp has in length and breadth pulling force than little, fiber dispersion good uniformity, characteristics such as papery outward appearance evenness is good).
