Abstract

本发明涉及一种特别适用于制造香烟过滤嘴的过滤材料，其特征在于，将熔融的增塑的乙酸纤维素以喷熔法涂敷于预制的滤纸带上。

Description

一种用于制造香烟过滤嘴的过滤材料及其制备方法
技术领域
本发明涉及权利要求1中前序部分所叙述的香烟过滤嘴，以及涉及权利要求17中前序部分所叙述的方法。
背景技术
从基本概念看，纤维素过滤材料越来越多地用于香烟过滤嘴。对于淡味和超淡味香烟(Leicht-und Ultra-Leicht-Cigeretten)的设计，多采用纸作过滤嘴，这是由于纸具有非常好的滞留特性。但与通常使用的乙酸纤维素过滤嘴相比，其主要缺点是纸过滤嘴会引起味道的变化。所以纸过滤材料不适宜用于单过滤嘴。而仅能与其他过滤材料一起用于制成所谓的双过滤嘴、复式过滤嘴或多重过滤嘴。但是，多重过滤嘴的制造特别复杂，而且成本很高。
US-A-3900037中公开了一种过滤材料，其中在由棉网材料(“薄棉纸”)制成的载体层上涂敷乙酸纤维素涂层。将所制成的过滤材料插入过滤管中，并截成正常香烟过滤嘴的长度。因此这种过滤材料看起来好像乙酸纤维素位于缠结的纤维网似的载体层上，像类似着色层那样的大体上均匀的稠密的层。
发明内容
本发明的目的是提供一种过滤材料以及制造用于香烟过滤嘴的过滤材料的方法，它兼有乙酸纤维素及纸的优点。
具体实施方式
权利要求1和17的各自的特征部分可用于达到此目的。
根据本发明，将乙酸纤维素以熔喷法涂敷于纸带上。由此就兼备有纤维素的优良滞留特性及乙酸纤维素的选择滞留特性。意外地发现，用这种材料制造的单过滤嘴在滞留特性和味觉特性方面与具有相同总滞留率的通常的多重过滤嘴相当。这种新过滤材料的制备可采用熔喷法及使用光滑纸带或预皱化过的纸带来实现，纸带以多层，优选以单层平放，其重量范围为8～50g/m2，优选为15～30g/m2，喷出的熔融乙酸纤维素的乙酸化的程度为1～3，优选为1.2～2.8，更优选为1.5～2.5，最优选为1.7～2.6。这种乙酸纤维素最好是一种用三醋精增塑处理过的乙酸纤维素，三醋精软化乙酸纤维素的表面，使纤维在交叉处或接触处相互粘接。一个优选方案中，乙酸纤维素包含达20％的增塑剂。另一个优选方案中，乙酸纤维素是以0.1～2旦的纤维纤度涂敷到滤纸上。
根据本发明的一个实施方案所提供的过滤材料中，滤纸含有高表面积的材料，如活性炭、海泡石等。根据本发明的另一个实施方案所提供的过滤材料中，滤纸含有高表面积的材料，该材料含有调节香味及口味的添加剂。优选，该添加剂是维生素。
根据纸对乙酸纤维素的用量比例情况，使用一种粘接剂是有利的。这种粘接剂可以是一种熔融粘接材料或例如一种改性的可挤出的和可熔的淀粉浆。从经济角度看，后者是值得推荐的。但在所有情况下都必需注意，粘接剂的加工温度不能影响其后涂敷的纤维素纤维的性能。一个优选方案中，乙酸纤维素是以0.1～2旦的纤维纤度涂敷到纸上。
