Description
本发明属于烟草测试技术领域，具体涉及一种根据色牢度测定烟用接装纸粘唇力的方法。
卷烟滤嘴主要是由醋酸纤维、成型纸、接装纸三层组成。其中接装纸，又名水松纸，用于包裹在过滤嘴外面并将滤嘴粘接到烟条末端。接装纸是通过对接装原纸进行印刷涂布及其他方式加工后得到的一种装潢纸，常为软木色或不透明的白色，具有改善外观的作用。接装纸同吸烟者嘴唇直接接触，在天气干燥时，消费者吸食卷烟的时候，由于可能会有少量唾液将接装纸蘸湿，在吸烟过程中又慢慢干燥，在嘴唇残留的唾液蛋白质会对接装纸有粘合作用，导致滤嘴上的接装纸粘连在嘴唇皮肤上，甚至粘扯嘴唇出现撕破、出血的现象，吸食完后不能将滤嘴顺利吐出，严重影响卷烟消费体验感。良好的接装纸应该是在抽吸过程中不粘唇。
目前，国内外卷烟滤嘴接装纸的研究热点多集中于其热解特性、低引燃性、有害元素含量、卷烟纸改性及改性后一氧化碳的释放能力、毒理性及安全性评价等方面。而其粘唇力的筛选或者判定没有相关的研究，涉及粘唇方面均是对接装纸的配方和工艺进行改进，并没有具体的筛选方法或者是判定方法。例如发明专利“一种不粘嘴防止唇舌干燥的香味保健水松纸及其制备方法”中描述了水松纸的工艺配方，但在效果检测上只是检测了原纸的纵向抗张强度和透气度，没有提及是否有粘唇力的判定。实用新型专利“一种防粘唇防污染的过滤嘴”在水松纸外涂上一层保护膜和“一种多功能水松纸”目的是防粘唇、赋香、阻燃等，在水松纸外层复合水果香防水层和防护膜层，但并未提及防粘唇的判定结果。行业内也没有相应的标准进行规范，各大企业仅凭专业人员的评吸判断，具有很大的主观性和不确定性，为了能判定不同工艺、不同类型接装纸是否对嘴唇有粘粘性/力，亟需建立相应客观的筛选检测方法。
接装纸的粘唇程度，现有技术的评价方法为：在人工抽吸过程中，通过抽吸者的主观感觉给出粘唇程度进行定性打分，然后给出接装纸的粘唇性能是否合 格。这种评价方法的缺点是完全凭人工主观感觉，重现性较差；并且不能严格定量结果。
本发明首次将色牢度的测量方法用于接装纸粘唇力的评价，建立了色牢度的测量结果与烟用接装纸粘唇力之间的一致性的定量关系，使接装纸的粘唇程度进行了定量化。与人工评吸相比，重现性大大增强。

2、本发明的人工唾液的成分接近人体分泌的唾液的成分，使用本发明的人工唾液测定的沾色牢度级的与烟用接装纸粘唇力之间的定量关系的一致性较好。
3、本发明首次定义：当沾色牢度级数SSR≥4时，确定烟用接装纸粘唇力等级结果为0级，为不粘唇；当沾色牢度级数3≤SSR＜4时，确定烟用接装纸粘唇力等级结果为1级，为轻度粘唇；当沾色牢度级2≤SSR＜3时，确定烟用接装纸粘唇力等级结果为2级，表现为中度粘唇；当沾色牢度级数1≤SSR＜2时，确定烟用接装纸粘唇力等级结果为3级，表现为重度粘唇；当沾色牢度级数SSR＜1时，确定烟用接装纸粘唇力等级结果为4级，表现为严重粘唇。该定义为本领域的技术人员提供了烟用接装纸粘唇力定量化的思路。
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合具体实施例，进一步阐述本发明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。下列实施例中未注明具体条件的实验方法，通常按照常规条件。除非另外说明，所述百分比和份数按重量计算。
本发明公开了一种烟用接装纸粘唇力的测定方法，包括如下步骤：在人工唾液浸润条件下，使得烟用接装纸与试样玻璃纤维纸紧密贴合在一起，在负重条件下一段时间后，测试试样玻璃纤维纸与空白玻璃纤维纸的色差值，得到试样玻璃纤维纸的沾色牢度级别，然后建立沾色牢度级别与烟用接装纸粘唇力之间的定量关系，即可判断烟用接装纸粘唇力的大小。具体步骤为：①将两张试样玻璃纤维纸浸泡在预先配置好的人工唾液中10s取出，擦拭去掉多余的液体；②将一张浸润后的试样玻璃纤维纸光滑面向上放在玻璃片或聚丙烯腈树脂片上，将烟用接装纸样品置于其上，然后将另一张浸润后的试样玻璃纤维纸光滑面向下盖在烟用接装纸样品上，再将第二块玻璃片或聚丙烯腈树脂片放在第二张玻璃纤维纸上，最后用塑料膜将其整体包裹起来；将砝码置于其上放置10min；③将步骤② 的两张试样玻璃纤维纸取出，将与接装纸印刷面接触的试样玻璃纤维纸面向上避光放置，然后自然晾干；④测量步骤③的试样玻璃纤维纸与空白玻璃纤维纸颜色得到明度值(L
*)和色品指数(a
*、b
*)，计算两者之间的色差值ΔE
CIELAB和灰度差ΔE
GS，然后计算烟用接装纸样品的沾色牢度级数SSR；⑤根据步骤④沾色牢度级数SSR定义烟用接装纸粘唇力等级。所述人工唾液的的组成表1所示。
玻璃纤维纸的规格为60mm×90mm，且应满足以下条件：定量为70g/m2，按照GB/T 461.1测得的毛细吸液高度为200mm/10min，不含荧光增白剂和湿强剂，不含纤维素纤维；所述烟用接装纸样品的规格为50mm×30mm；所述砝码质量为1kg。色差值ΔE
CIELAB和灰度差ΔE
GS，以及烟用接装纸样品的沾色牢度级数SSR的计算方法如下：
其中ΔL*＝L
S*-L
R*；Δa*＝a
S*-a
R*，Δb*＝b
S*-b
R*，L
S*、a
S*和b
S*分别为空白玻璃纤维纸的明度值(L*)和色品指数(a*、b*)，L
R*、a
R*和b
R*分别为试样玻璃纤维纸的明度值(L*)和色品指数(a*、b*)；当ΔE
GS≥4.26时，SSR＝6.1-1.45ln(ΔE
GS)，当ΔE
GS≤4.26时，SSR＝5-0.23ΔE
GS。根据上述计算结果，沾色牢度级数SSR与烟用接装纸粘唇力等级定义如下：当沾色牢度级数SSR≥4时，确定烟用接装纸粘唇力等级结果为0级，为不粘唇；当沾色牢度级数3≤SSR＜4时，确定烟用接装纸粘唇力等级结果为1级，为轻度粘唇；当沾色牢度级2≤SSR＜3时，确定烟用接装纸粘唇力等级结果为2级，表现为中度粘唇；当沾色牢度级数1≤SSR＜2时，确定烟用接装纸粘唇力等级结果为3级，表现为重度粘唇；当沾色牢度级数SSR＜1时，确定烟用接装纸粘唇力等级结果为4级，表现为严重粘唇。测定方法各步骤均在40±2℃下进行。
实施例1
本实施例对20个不同样品采用上述方法进行测定，并和和现有人工评吸方法进行检测，检测结果如表2所示。其中人工评吸采用多组编码暗评，即评吸人员提前不知道样品的接触角情况下，将同一样品分成多组随机编码，让评吸人员评吸，根据粘唇情况给出五个等级：0级、1级、2级、3级、4级；其中0级为不粘唇，粘唇等级的分别为1级为轻度粘唇、2级为中度粘唇、3级为重度粘唇和4级为严重度粘唇。
表2沾色牢度级数SSR及与人工评吸结果对比
实施例2
本实施例对20个不同样品采用上述方法进行测定，并和和现有人工评吸方法进行检测，检测结果如表3所示。
表3沾色牢度级数SSR及与人工评吸结果对比
由表2和表3可知，本发明的检测方法与人工评吸检测结果基本一致。本发明方法能客观、准确对烟用接装纸是否有粘唇力进行定量，易于推广应用，为烟支粘唇力的标准制定提供依据。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的 技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
