Description

一种滤袋滤纸及茶叶滤袋和袋装茶叶  Filter bag filter paper and tea filter bag and bagged tea
技术领域 Technical field
本发明涉及造纸领域， 尤其涉及一种滤袋滤纸及茶叶滤袋和袋装茶叶。  The invention relates to the field of papermaking, in particular to a filter bag filter paper, a tea bag and a bag of tea leaves.
背景技术 Background technique
茶叶滤纸是一种常用滤纸， 用于茶叶过滤， 人们在日常喝茶时， 烦于茶叶上浮和 倒剩茶， 产生了茶袋， 当然也用于国人煎中草药， 特别合适。 如果厚度大点， 我们也用 这种具过滤性能的材料包装干燥剂、 碳等吸附材料。  Tea filter paper is a commonly used filter paper for tea filtration. When people drink tea daily, they are troubled by tea floating and leftover tea, which produces tea bags. Of course, it is also suitable for Chinese people to fry Chinese herbal medicine. If the thickness is large, we also use this filter material to package desiccant, carbon and other adsorbent materials.
茶叶滤纸分为热封型和分热封型， 区别就是是否使用了热封材料。 热封材料一般 做成纤维状， 与纸浆混抄， 成纸后进行热定型， 即在高温下让热封纤维收缩成点状， 然 后在茶袋包装时， 这些点状的热封物质在受热时与另一面的热封纤维相粘， 这样纸就被 封起来， 可以形成茶袋。 当然， 除了包茶叶， 也可以包其它材料， 如碳粒、 碳粉、 干燥 剂等物质。  Tea filter paper is divided into heat seal type and partial heat seal type, the difference is whether the heat seal material is used. The heat sealing material is generally made of a fiber, mixed with the pulp, and heat-set after the paper is formed, that is, the heat-sealed fiber is shrunk into a dot shape at a high temperature, and then when the tea bag is packaged, the point-like heat-sealing substance is heated and The other side of the heat-sealing fiber is so sticky that the paper is sealed and a tea bag can be formed. Of course, in addition to tea, other materials such as carbon particles, carbon powder, and desiccant may be included.
这种热封纤维目前较多使用聚丙烯纤维（PP)、 聚乙烯纤维（PE)、 复合纤维（ES) 等石油产品。 由于使用到石油产品， 在能源紧张的今天， 就显得不够环保， 同时， 石油 产品的环境友好性是很差的， PP 纤维在自然环境中， 几百年都不会降解， 同时石油产 品不能再生， 是一次性资源， 使用一种能热封的非石油环境友好产品是必须的。  Such heat-sealing fibers are currently mostly used in petroleum products such as polypropylene fibers (PP), polyethylene fibers (PE), and composite fibers (ES). Due to the use of petroleum products, energy shortages are not environmentally friendly today. At the same time, the environmental friendliness of petroleum products is very poor. PP fibers do not degrade in the natural environment for hundreds of years, and petroleum products cannot be regenerated. , is a one-time resource, the use of a non-oil environmentally friendly product that is heat-sealed is a must.
发明内容 Summary of the invention
为了解决上述背景技术中的缺陷， 本发明的一个目的是一种滤袋滤纸， 该滤袋滤纸 采用聚乳酸纤维， 是一种宽温度的热封材料， 对热封机的适应能力强， 具有完全自然循 环和能生物分解的特点。 本发明的另外一个目的是提供上述的滤袋滤纸的应用。  In order to solve the above drawbacks in the background art, an object of the present invention is a filter bag filter paper, which is a polylactic acid fiber, which is a wide temperature heat sealing material and has strong adaptability to a heat sealer. Completely natural circulation and biodegradable features. Another object of the present invention is to provide the use of the filter bag filter described above.
为了实现上述的第一个目的， 本发明采用了以下的技术方案- 一种滤袋滤纸， 该滤纸包括主体纸浆纤维和热封纤维混合抄纸制得， 所述热封纤维 采用聚乳酸纤维， 聚乳酸纤维占全部纤维总质量的 10%〜45%。  In order to achieve the above first object, the present invention adopts the following technical solution - a filter bag filter paper comprising a main pulp fiber and a heat-sealing fiber mixed papermaking, and the heat-sealing fiber is made of polylactic acid fiber. Polylactic acid fibers account for 10% to 45% of the total mass of all fibers.
作为优选， 上述的聚乳酸纤维占全部纤维总质量的 15%〜30%。  Preferably, the above polylactic acid fiber accounts for 15% to 30% of the total mass of all the fibers.
作为优选， 上述的滤纸的定量为 16.5〜45g/cm2。 Preferably, the above-mentioned filter paper has a basis weight of 16.5 to 45 g/cm 2 .
本发明所述的聚乳酸纤维（PLA纤维） 的别名，属于芳香族聚酯纤维，但不含芳香环。 其合成原料来自天然的植物 (如玉米等)，是新一代环保型聚酯合成纤维。 玉米纤维埋入 土中一年后强度会消失并降解,如果与其它废弃物一起堆埋，几个月就可以分解，降解产 物为无害的乳酸、 二氧化碳和水，燃烧时不产生有毒物质。 聚乳酸纤维是一种可完全生 物降解的合成纤维,它可从谷物 (如玉米等） 中取得。首先对玉米等原料进行发酵制得乳 酸，然后经缩合、聚合反应制成聚乳酸，再利用耦合剂制成具有良好机械性能的较高分子 量的聚乳酸，最后经过关键的化学改性,将其强度、 保水性提升,并将其纤维化。 由于乳 酸是存在于动物、植物及微生物内的天然物质，很容易自然降解，该纤维完全不使用石油 等化工原料,其废弃物在土壤和海水中的微生物作用下,可分解成二氧化碳和水，完成自 然循环,不会散发毒气,不会对地球环境造成污染。 由于该纤维的初始原料为玉米等谷类， 其再生循环周期短,大约为 1〜2 年,其产生的二氧化碳由于植物光合作用，在大气中的 含量会逐渐减少。 玉米纤维以价廉量多的淀粉作原料，又具有完全自然循环和能生物分 解的特点。 玉米纤维 60°C时开始软化， 175°C时完全熔解， 可以作为一种宽温度的热封 材料， 对热封机的适应能力强。 The polylactic acid fiber (PLA fiber) of the present invention is an alias of an aromatic polyester fiber but does not contain an aromatic ring. Its synthetic raw materials come from natural plants (such as corn) and are a new generation of environmentally friendly polyester synthetic fibers. After the corn fiber is buried in the soil, the strength will disappear and degrade. After being buried with other wastes, it can be decomposed in a few months. The degradation products are harmless lactic acid, carbon dioxide and water, and no toxic substances are produced when burning. Polylactic acid fiber is a kind of complete Degraded synthetic fiber, which can be obtained from grains such as corn. First, the raw materials such as corn are fermented to obtain lactic acid, and then polylactic acid is formed by condensation and polymerization, and then a higher molecular weight polylactic acid having good mechanical properties is prepared by using a coupling agent, and finally subjected to key chemical modification. Strength, water retention, and fiberization. Since lactic acid is a natural substance present in animals, plants and microorganisms, it is easily degraded naturally. The fiber does not use chemical materials such as petroleum at all, and its waste can be decomposed into carbon dioxide and water under the action of microorganisms in soil and seawater. Complete the natural circulation, no poison gas will be emitted, and it will not pollute the global environment. Since the initial raw material of the fiber is a cereal such as corn, the regeneration cycle is short, about 1 to 2 years, and the carbon dioxide produced by the fiber is gradually reduced in the atmosphere due to photosynthesis of the plant. Corn fiber is a raw material with a low price and a large amount of starch, and has the characteristics of complete natural circulation and biodegradation. Corn fiber begins to soften at 60 ° C and completely melts at 175 ° C. It can be used as a wide temperature heat sealing material and has strong adaptability to heat sealing machines.
玉米纤维的加入量一般控制在 10%- 45%， 低于 10%， 纸的热封强度不好， 茶袋封口处 容易开裂， 高于 45%, 成本上升并有成膜的可能。 最佳的加入量应控制在 15%-30%。  The amount of corn fiber added is generally controlled at 10% - 45%, less than 10%. The heat seal strength of the paper is not good, and the tea bag seal is prone to cracking, higher than 45%, and the cost rises and the film formation is possible. The optimum amount to be added should be controlled at 15%-30%.
