Description

一种聚乳酸纤维滤棒卷烟结构及其制备方法 技术领域
本发明涉及烟支制备技术领域,尤其是,本发明涉及一种聚乳酸纤维滤棒卷烟结构及其制备方法。
背景技术
聚乳酸(poly lactic acid,PLA)是由可再生植物资源中的淀粉发酵制取乳酸,而后经化学合成制备成高分子材料,具有良好的循环再生性和生物降解性,具有以下特点:1、以可再生的植物资源(玉米、小麦、甜菜、大米、土豆、山芋等)以及有机废弃物(玉米芯或其它农作物的根、茎、叶、皮等)为原料,摆脱了对木材和石油资源的依赖,符合可持续发展的要求;2、能够完全生物降解,在自然环境中经过一定时间会自然分解为水和二氧化碳,不造成环境污染,产生的二氧化碳通过植物光合作用得到重新利用,成为一个永恒的、封闭的碳循环系统,是名副其实的“绿色材料”;3、与涤纶、锦纶、腈纶三大合成纤维相比,生产聚乳酸纤维的能源消耗较低,是一种相对低资源环境负荷的高分子材料;4、具有良好的加工性能,可采用一般热塑性树脂的熔融纺丝方法生产丝束。
目前,聚乳酸纤维已经被开发出用于烟用丝束等领域,但是由于聚乳酸分子结构及聚合状态、丝束形态差异,过滤作用差异较大,对卷烟主流烟气中致香物质的过滤差异更大,同样吸阻、类似单旦总旦的聚乳酸丝束与醋纤丝束虽然对卷烟烟气的指标较为接近,但在实际的抽吸过程中会发现,感官质量还是很大的差异。
其中聚乳酸纤维丝束相比于醋纤丝束具有选择性过滤的特性,聚乳酸除了对烟丝香味具有较低过滤性可以增加抽吸口感,聚乳酸纤维丝束对于烟气中的木质气这一影响抽吸口感的气体的高过滤性,但是对于烟气中的挥发性羰基物、HCN、单元酚类物质以及一些其它气相物质过滤效果稍弱,烟气中此类气相物质会增加卷烟刺激性,会降低抽吸口感。
由于烟气成分的物理化学性质极其复杂,过滤过程中能发生作用的时间极短,要实现理想的选择性去降低是很困难的;所以导致聚乳酸纤维丝束滤棒难以确保烟支抽吸时的各物质即有鲜明风格特色,又保证符合国家标准的质量要求。
因此为了解决上述问题,设计一种合理高效的聚乳酸纤维滤棒卷烟结构对我们来说是很有必要的。
发明内容
本发明的目的在于提供一种聚乳酸纤维滤棒卷烟结构,其设置简单,通过聚乳酸纤维丝束和活性炭的配合,有效降低抽吸温度,确保烟气中抽吸香气,且可以有效利用活性炭弥补聚乳酸纤维丝束的选择性过滤特点,对挥发性羰基物进行有效吸附,既可以确保抽吸口感具有鲜明风格特色,又可以确保吸入烟气满足国家标准质量要求。

现在将参照附图来详细描述本发明的各种示例性实施例。应注意到:除非另外具体说明,否则在这些实施例中阐述的模块和步骤的相对布置和步骤不限制本发明的范围。
同时,应当明白,为了便于描述,附图中的流程并不仅仅是单独进行,而是多个步骤相互交叉进行。
在本发明的描述中,需要说明的是,术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,或者是本发明产品使用时惯常摆放的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。此外,术语“第一”、“第二”等仅用于区分描述,而不能理解为指示或暗示相对重要性。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的,决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法及系统可能不作详细讨论,但在适当情况下,技术、方法及系统应当被视为本说明书的一部分。
实施例一:如图1所示,一种聚乳酸纤维滤棒卷烟结构,包括滤棒段1和发烟段2,所述滤棒段1包括聚乳酸纤维丝束11和用于包覆所述聚乳酸纤维丝束11的成形纸12,所述成形纸12侧面设置有活性炭层13;所述发烟段2中的烟丝比例不低于60%;
使得在所述发烟段2中烟丝比例不低于60%的烟支燃烧产生烟气时,所述聚乳酸纤维丝束11有效对烟气进行降温并具有对烟气中的木质气的高过滤性,但所述聚乳酸纤维丝束11对烟气中挥发性羰基物具有低过滤性,而所述活性炭层13有效的对挥发性羰基物进行吸附,增加抽吸口感及安全性。
在本发明中,卷烟结构采用的是聚乳酸纤维滤棒对发烟段2中的烟气进行过滤,也就是主要利用的是聚乳酸纤维丝束的过滤性。
在本发明设计时,考虑采用聚乳酸纤维丝束进行烟气过滤,是希望利用聚乳酸纤维丝束对高温烟气的有效降温的能力,以及聚乳酸纤维丝束相比于醋纤丝束更好的方便烟气中的香气物质通过的特性,可以对烟气进行有效降温并且保证烟气香气,提高抽吸口感。
由于烟气成分的物理化学性质极其复杂,滤嘴的过滤过程中能发生作用的时间极短,要实现理想的选择性去降低是很困难的;但是烟气中的成分物质主要包括气相物质与粒相物质,其中烟气的香气主要是依附于焦油等粒相物质,聚乳酸纤维丝束具有较低的过滤性,可以保证烟气中的致香成分较高。
另外就是过滤气相物质,气相物质又包括木质气、挥发性羰基物、HCN、单元酚类物质以及一些其它气相物质;这些气体都会影响抽吸口感,聚乳酸纤维丝束选择过滤性中,对木质气具有较高的过滤性,但是对于挥发性羰基物、HCN、单元酚类物质以及一些其它气相物质具有较低的过滤性。
气相物质的去除主要有三种方式来完成,吸附(如加入活性炭的滤嘴)、吸收和化学反应。常温下的永久性气体,如CO、N2都不能被活性炭吸附去除;其他一些气体都会被不同程度地吸附,其中刚好挥发性羰基物、HCN、单元酚类物质等可借助活性炭高度选择地去除。
于是对聚乳酸纤维丝束和活性炭进行各种配方比重下进行配合,对烟气进行过滤实验,多次实验之后发现,既有效降低烟气温度,还能保证烟气香气饱满,还能利用聚乳酸纤维丝束对木质气进行过滤,以及利用活性炭去与聚乳酸纤维丝束配合,对聚乳酸纤维丝束过滤较差的挥发性羰基物、HCN、单元酚类物质等进行有效吸附。
那么,本发明中,利用侧面涂覆有活性炭层的成形纸12包覆聚乳酸纤维丝束11形成的滤棒段1,可以有效对发烟段2中的烟气进行优化过滤,既可以确保抽吸口感具有鲜明风格特色,又可以确保吸入烟气满足国家标准质量要求。
需要注意的是,发烟段2中的物质包括烟丝和梗丝,烟丝含量越高,烟支烟气越优,原因是烟丝燃烧产生烟气中的致香物质越饱满;反之梗丝含量越高,烟支烟气越劣,原因是梗丝燃烧产生的烟气中的木质气多,且香气较少。
那么为了使得本发明的卷烟结构,有效确保抽吸口感具有鲜明风格特色,需要确保发烟段2中的烟丝比例不低于60%,烟气中具有足够的香气通过滤棒段1,且其中的木质气可以有效被滤棒段1过滤。
需要注意的是,在卷烟制备过程中,需要获取发烟段2中的烟丝比例以及发烟段总质量;根据烟丝比例,设置预定长度的聚乳酸纤维丝束;以及根据烟丝比例,在成形纸侧面涂覆预定厚度和浓度的活性炭层;一般来说,发烟段2的烟丝比例需要考虑之外,还要考虑发烟段总质量,并且提前保存数据库,在某一个烟丝比例以及某一个发烟段总质量,建立理论需要的聚乳酸纤维丝束长度以及活性炭层浓度厚度,生产制备时,烟丝比例以及发烟段总质量,再进行查表(数据库)即可进行生产。
本发明一种聚乳酸纤维滤棒卷烟结构,其设置简单,通过聚乳酸纤维丝束和活性炭的配合,有效降低抽吸温度,确保烟气中抽吸香气,且可以有效利用活性炭弥补聚乳酸纤维丝束的选择性过滤特点,对挥发性羰基物进行有效吸附,既可以确保抽吸口感具有鲜明风格特色,又可以确保吸入烟气满足国家标准质量要求。
实施例二,如图1、2所示,仅为本发明的其中一个实施例,在实施例一的基础上,本发明一种聚乳酸纤维滤棒卷烟结构中,所述聚乳酸纤维丝束11和成形纸12的数量均至少为一个;可以设置多层结构的聚乳酸纤维丝束11和成形纸12,使得过滤效果更优。
在本发明的一个实施例中,所述成形纸12包括内层成形纸121和设置于所述内层成形纸外侧的外层成形纸122,所述内层成形纸内侧以及所述内层成形纸与外层成形纸之间均设置有聚乳酸纤维丝束11。
当然,内层成形纸121的内外两侧都设置有活性炭层13,外层成形纸122最好只有内侧设置有活性炭层13。
在本发明的一个实施例中,所述发烟段2外侧设置有卷烟纸,所述滤棒段1和发烟段2通过接装纸进行连接;在具有接装纸设置于成形纸12的外侧的情况下,外层成形纸122外侧也可以设置活性炭层13。
在这里,活性炭层13最好是涂布的方式涂覆于成形纸12的侧面。
另外,为了更好的对聚乳酸纤维丝束11低过滤性的物质进行吸附,还可以在所述聚乳酸纤维丝束11中设置活性炭悬浮液111,进一步对部分物质进行吸附。
还有,所述发烟段2中设置有加香爆珠;进一步增加发烟段2烟气中的香气,且这些香气被聚乳酸纤维丝束11过滤量少,使得其利用率更高。
最后,所述聚乳酸纤维丝束11为皮芯型丝束结构,所述聚乳酸纤维丝束11制备原料中的左旋乳酸单体含量不低于90%,确保聚乳酸纤维的结晶度,丝束尺寸热稳定性高;还可以在聚乳酸原料中添加三乙酸甘油酯,在三乙酸甘油酯的作用下,丝束溶胀且粘结,得到粘结良好的皮芯型结构聚乳酸丝束。
实施例三,如图3所示,本发明还提供上述所有实施例中的一种聚乳酸纤维滤棒卷烟结构的制备方法,包括以下步骤:
S1:制备发烟段,使得发烟段中的烟丝比例不低于60%;
S2:制备聚乳酸纤维丝束,且聚乳酸纤维丝束制备原料中的左旋乳酸单体含量不低于90%;
S3:制备成形纸,成形纸裁切之后,在成形纸侧面涂覆活性炭层;
S4:制备滤棒段,使用侧面涂覆有活性炭层的成形纸包覆聚乳酸纤维丝束;
S5:卷烟接装,对滤棒段和发烟段进行接装。
需要注意的是,在执行步骤S1时,获取发烟段中的烟丝比例以及发烟段总质量;
在执行步骤S2时,根据烟丝比例以及发烟段总质量,设置预定长度的聚乳酸纤维丝束;
在执行步骤S3时,根据烟丝比例以及发烟段总质量,在成形纸侧面涂覆预定厚度和浓度的活性炭层。
本发明一种聚乳酸纤维滤棒卷烟结构及其制备方法,其设置简单,通过聚乳酸纤维丝束和活性炭的配合,有效降低抽吸温度,确保烟气中抽吸香气,且可以有效利用活性炭弥补聚乳酸纤维丝束的选择性过滤特点,对挥发性羰基物进行有效吸附,既可以确保抽吸口感具有鲜明风格特色,又可以确保吸入烟气满足国家标准质量要求。
本发明不局限于上述具体的实施方式,本发明可以有各种更改和变化。凡是依据本发明的技术实质对以上实施方式所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围。
