Description
Technical Field
The invention belongs to the technical field of analysis and detection, and particularly relates to a method for detecting lip adhesion of cigarette tipping paper.
Background
The cigarette filter tip mainly comprises three layers of acetate fiber, forming paper and tipping paper. Among these are tipping paper, also known as tipping paper, which is used to wrap around the outside of the filter and to adhere the filter to the end of the tobacco rod. The tipping paper is a decorative paper obtained by printing and coating tipping base paper and processing the tipping base paper in other modes, is usually cork color or opaque white color, and has the effect of improving the appearance. Connect dress paper with smoker's lip direct contact, it only uses coating or printing ink to print on the dress paper to connect generally, when weather is dry, when the consumer smokes the cigarette, because probably there is a small amount of saliva will connect dress paper to dip in wet, slowly dry again at the smoking in-process, there is the adhesive action to dress paper in the remaining saliva protein meeting of lip, lead to connecing on the filter tip dress paper adhesion on the lip skin, it tears the phenomenon that appears tearing, hemorrhage even to glue the lip, can not spit the filter tip smoothly after having smoked, seriously influence cigarette consumption and experience and feel.
At present, the hot research of cigarette filter tipping paper at home and abroad mostly focuses on the aspects of pyrolysis characteristics, low ignition performance, harmful element content, release capacity of carbon monoxide after modification of cigarette paper and modification, toxicological property, safety evaluation and the like. The screening or judgment of the lip adhesion force has no related research, the formulation and the process of the tipping paper are improved in the aspect of lip adhesion, and a specific screening method or a judgment method is not provided. For example, the invention patent 'a fragrant health care tipping paper which does not stick to mouth and prevents lips and tongue from drying and a preparation method thereof' describes a technical formula of the tipping paper, but only detects the longitudinal tensile strength and air permeability of the base paper in the aspect of effect detection, and does not mention the judgment of whether lip sticking force exists. The utility model discloses an "anti-pollution filter tip of antiseized lip" scribbles one deck protection film and "a multi-functional tipping paper" purpose on the tipping paper is antiseized lip, endows fragrance, fire-retardant etc. at the outer compound fruit fragrance waterproof layer of tipping paper and protective film layer, but does not mention the judged result of antiseized lip. The industry also has no corresponding standard for specification, and each large enterprise only depends on the evaluation and judgment of professionals, so that the method has great subjectivity and uncertainty, and a corresponding objective screening and detecting method is urgently needed to be established in order to judge whether tipping paper with different processes and different types has viscosity/force on lips.
