Description:
The invention provides a preparation method of non-heat-sealed tea bag filer paper made of pure wood pulp. The method comprises the steps that pulp obtained by mixing non-chlorine-bleached wood pulp fibers with water is fluffed; an adsorbent, a PAE wet strength agent, a reinforcing agent and other substances are added for processing, and the non-heat-sealed tea bag filer paper is obtained. According to the method, addition of filament pulp such as hemp pulp and the like with high cost is not needed, and the cost is lower; compared with a traditional preparation method, the uniform, flat and soft non-heat-sealed tea bag filer paper with high dry strength and wet strength can be obtained without a follow-up surface sizing or coating process, and the production cost and equipment investment can be reduced. 本发明提供了种简单经济的制备非热封型茶叶滤纸的方法,所述方法通过先将无氯漂木浆纤维和水混合得到的浆料进行疏解;然后添加吸附剂、PAE湿强剂以及增强剂等进行处理,得到非热封型茶叶滤纸。根据本发明的方法无需添加价格昂贵的麻浆等长纤维浆料,成本较低;与传统制备方法相比,无需后续表胶或涂布工艺,即可得到均匀、平整、柔软,干、湿强度高的非热封型茶叶滤纸产品,可降低生产成本及设备投资。
