已有中国发明专利(公开号：CN105155329A)公开了和纸胶带原纸及其生产方法；该产品原料上选用长纤维木浆、短纤维化学机械木浆、湿强剂、涂布胶乳、黄栢萃取液，通过打浆处理、加入助剂、过冷处理、抄造处理、涂布处理、成纸这些步骤获得和纸胶带原纸。该专利中所选用的化学机械木浆简称化机浆，化机浆的性质和用途：化学机械法制浆的化学预处理比化学法制浆的蒸煮过程温和得多，对原料的脱木素作用较小，对纤维素的破坏也少，仅分子量较低的半纤维素溶出较多,因此，所制得的化机浆一般含有较高的木素和纤维素组分。这种纸浆的物理强度介于化学浆与机械浆之间，能使成纸具有十分良好的挺度，其漂白性、水化和滤水性能比较接近于机械浆，滤水性能好。经过适当漂白的化机浆则多用于生产纸板、新闻纸、中低档印刷纸或配用于涂布加工原纸等。There is a Chinese invention patent (publication number: CN105155329A) disclosing washi tape base paper and its production method; the raw materials of this product are long fiber wood pulp, short fiber chemical mechanical wood pulp, wet strength agent, coating latex, cork extract Liquid, through the steps of beating treatment, adding additives, supercooling treatment, papermaking treatment, coating treatment, and paper forming, the washi tape base paper is obtained. The chemi-mechanical wood pulp used in this patent is referred to as chemi-mechanical pulp. The properties and uses of chemi-mechanical pulp: the chemical pretreatment of chemi-mechanical pulping is much milder than the cooking process of chemical pulping. The effect is small, and the damage to cellulose is also small. Only the hemicellulose with lower molecular weight is more dissolved. Therefore, the prepared chemical-mechanical pulp generally contains higher lignin and cellulose components. The physical strength of this kind of pulp is between chemical pulp and mechanical pulp, which can make the paper have very good stiffness, and its bleaching property, hydration and water drainage performance are relatively close to mechanical pulp, and the water drainage performance is good. Properly bleached chemical-mechanical pulp is mostly used in the production of cardboard, newsprint, medium and low-grade printing paper or as base paper for coating processing.

漂白阔叶木化学机械浆中有大量的纤维束存在，浆料疏解2小时后还有少量成束的纤维，必须要打浆到30°SR以上才没有纤维束，才能抄造匀度好的纸张。There are a large number of fiber bundles in bleached hardwood chemical mechanical pulp, and there are still a small amount of bundled fibers after the pulp is decomposed for 2 hours. It must be beaten to 30°SR or above to have no fiber bundles, so that paper with good formation can be produced.

黄栢萃取液即黄柏提取物(phellodendronbarkextract)提取于芸香科植物黄皮树或黄檗的干燥树皮。前者习称“川黄柏”，后者习称“关黄柏”。剥取树皮后，除去粗皮，晒干。黄柏别称黄檗、元柏、檗木、檗皮Chemicalbook，主要成分为小檗碱。用作苦味剂。具有抗微生物及原虫，降压，抗肾上腺素样作用，松弛血管平滑肌，兴奋子宫、膀胱、支气管、胃肠道，利胆及兴奋大脑皮层的作用。经过对比试验黄栢萃取液对提升和纸胶带抗老化性能没有明显的提升，在生产高性能和纸胶带原纸时可以不用添加。Phellodendron barkextract is extracted from the dry bark of the Rutaceae plant Phellodendron bark or Phellodendron barkextract. The former is commonly called "Sichuan Phellodendron", and the latter is commonly called "Guan Phellodendron". After peeling off the bark, remove the rough bark and dry it in the sun. Cortex Phellodendron is also known as Cortex Phellodendron, Yuanbai, Berberis Wood, Berberis Bark, and its main component is berberine. Used as a bittering agent. It has anti-microbial and protozoa, antihypertensive, anti-adrenaline-like effects, relaxes vascular smooth muscle, excites the uterus, bladder, bronchus, gastrointestinal tract, choleretic and excites the cerebral cortex. After comparative tests, Phellodendron Phellodendron extract did not significantly improve the anti-aging performance of washi tape, so it does not need to be added when producing high-performance washi tape base paper.

上述工艺不足之处有：1)和纸胶带原纸必须有很好的匀度，因为定量低，涂布或施胶前的定量一般控制在26-30g/m²，中国发明专利(公开号：CN105155329A)公开了和纸胶带原纸及其生产方法中该产品纤维原料上选用针叶木浆和短纤维化学机械木浆，而为了达到很好的外观匀度，就必须对阔叶木化学机械浆打浆到30°SR以上才没有纤维束，才能抄造匀度好的纸张。这种原料配比抄成的原纸紧度指标高，透气度指标低，不利于后道工序涂布液的吸收，这种纸手感会偏硬；如果含有阔叶木化机浆的混合浆只打到15-20°SR，抄造出的纸张中会有较多的纤维束引起的白点，总体纤维分布也不均匀，影响纸的外观质量；2)化学机械木浆本身硬度高，浆中含有较多木素，使成纸具有十分良好的挺度，含有25％阔叶木化机浆的纸张，会使最终产品手感偏硬。木片中纤维之间含有大量的木素把木片中的纤维粘合在一起，采用化机浆的生产方式，木片先经过化学预处理，化学预处理较温和，木素溶出量很少，再使用盘磨的机械力来把纤维强制分离开，这样处理后浆里纤维之间还有较大量的木素存在，成品浆中还有很多纤维没有单独疏解开，有较大部分是几根纤维粘合在一起，同时很多纤维在木片经过盘磨的机械摩擦过程中受到较大损伤，使成浆中的纤维和纤维束大小、长短极不规则，其中含有很多细小纤维，同时有较大部分纤维或纤维束颗粒尺寸远大于单根纤维尺寸，用这种浆抄的纸张空隙偏大，纸透气度偏低，紧度偏高，不利于纸张的耐水、耐溶剂性能，容易渗水、渗溶剂；3)从表1中可看到漂白阔叶木化机浆亮度只有76.1％，比其他漂白化学浆亮度低约10％，这样抄造出的纸张亮度会低一些，影响白纸的外观质量，如果做彩色的和纸，因原纸亮度低，染成的纸张颜色会不够艳丽，影响纸的外观质量；4)化学机械木浆还有一明显缺点：漂白化机浆中还残留有较多木素，抄成纸后极易发生返黄现象，抗老化性能差，纤维同时变脆，易折断，强度下降明显；5)该技术只经过一道涂布，同时上胶量少，纸表面的封闭性不够，不利于纸张的耐水、耐溶剂性能；6)纸没有经过超级软压光，纸表面光泽性和封闭性也相对较差，纸的手感也会相对偏硬。The disadvantages of the above process are: 1) The base paper of the washi tape must have a good evenness, because the basis weight is low, and the basis weight before coating or sizing is generally controlled at 26-30g/m² , the Chinese invention patent (publication number: CN105155329A) discloses Japanese paper tape base paper and production method thereof, selects coniferous wood pulp and short fiber chemical mechanical wood pulp on the fiber raw material of this product, and in order to reach good appearance uniformity, just must beat hardwood chemical mechanical pulp to Above 30°SR, there will be no fiber bundles, and paper with good evenness can be produced. The base paper made of this kind of raw material ratio has high tightness index and low air permeability index, which is not conducive to the absorption of coating liquid in the subsequent process. This kind of paper will feel hard; if the mixed pulp containing hardwood chemical pulp is only To 15-20°SR, there will be more white spots caused by fiber bundles in the paper produced, and the overall fiber distribution is not uniform, which will affect the appearance quality of the paper; 2) The chemical mechanical wood pulp itself has high hardness, and the pulp contains More lignin makes the paper have very good stiffness, and the paper containing 25% hardwood chemical pulp will make the final product feel harder. There is a large amount of lignin between the fibers in the wood chips to bind the fibers in the wood chips together. The production method of chemical mechanical pulp is adopted. The wood chips are chemically pretreated first. The chemical pretreatment is relatively mild, and the amount of lignin dissolved is very small, and then used The mechanical force of the disc mill is used to forcibly separate the fibers. In this way, there is still a large amount of lignin between the fibers in the pulp after treatment. There are still many fibers in the finished pulp that have not been loosened separately. Together, at the same time, many fibers are greatly damaged during the mechanical friction process of the wood chips through the disc grinding, so that the size and length of the fibers and fiber bundles in the pulp are extremely irregular, which contains many fine fibers and a large part of them Or the particle size of the fiber bundle is much larger than the size of a single fiber. The paper made with this kind of pulp has a large void, low air permeability and high tightness, which is not conducive to the water resistance and solvent resistance of the paper, and is easy to seep water and solvent; 3) It can be seen from Table 1 that the brightness of bleached hardwood chemical pulp is only 76.1%, which is about 10% lower than that of other bleached chemical pulps. In this way, the brightness of the paper produced will be lower, which will affect the appearance quality of white paper. For colored washi paper, due to the low brightness of the base paper, the color of the dyed paper will not be bright enough, which will affect the appearance quality of the paper; 4) There is another obvious disadvantage of chemical mechanical wood pulp: there is still a lot of lignin in the bleached mechanical pulp, which is difficult to copy. After the paper is finished, yellowing phenomenon is very easy to occur, the anti-aging performance is poor, the fiber becomes brittle at the same time, easy to break, and the strength drops significantly; It is not conducive to the water resistance and solvent resistance of the paper; 6) The paper has not been super soft calendered, the gloss and sealing of the paper surface are relatively poor, and the hand feeling of the paper will be relatively hard.
