Description
Technical field
The present invention relates to preparation method and the application thereof of functionalization tow for a kind of filter stick, belong to tobacco filtering material Application Areas.
Background technology
Filter tip is as the bridge between smoker and main flume, part harmful components in can not only filtering flue gas, and on cigarette, be hinged with filter tip, total particulate matter in can effectively catching cigarette mainstream flue gas, reduce tar content, reducing the harm of flue gas to health and environment, is means the most directly and the most intuitively in Tar technology.At present, countries in the world are more and more paid attention to the exploitation of filter stick for cigarettes material and plug configuration, use functional form filter stick to be the trend of tobacco business reducing tar and reducing harm from now on.Domestic each tobacco enterprise generally adopts the common filter tip of acetate fiber or propionic acid fiber, and there is selective height, function fiber tow filter rods application study that absorption property is good is less.
Along with growing to even greater heights and the generally enhancing of consumer to smoking and health problem concern of world's Anti-smoking activity, market is more and more higher to the requirement of cigarette, the pressure that tobacco faces is increasing, and some countries have required to mark or reduce harmful substance listed in Hoffmann list especially in recent years.How making tar and the harmful components burst size thereof of cigarette reduce, keep again cigarette odor-absorbing to make consumer obtain physiology simultaneously and meet, is the ultimate challenge that Cigarette design faces, and common filter tip still can not meet the requirement of this respect at present.
Electrostatic spinning is to utilize the stretching of high-pressure electrostatic to make polymer solution or burning melt liquid formation injection thread and spray and formation polymer nanofiber process from spinneret orifice.Electrostatic spinning technique principle is referring to accompanying drawing 1, the spinning solution thread flowing out from shower nozzle pore, accelerated motion division and form thread bunch under electrostatic force are condensed or are cured as microfilament after solvent evaporation or melt cooling, with the form of nonwoven fabric, are deposited on receiving system.Spinning solution is connected with the positive pole of high-voltage D.C. generator, and receiving system is negative pole ground connection.
By changing the composition of electrostatic spinning nano fiber, can obtain the fiber of different physicochemical properties.This can realize by add various ingredients in spinning solution, and every kind of component of adding can make product have a kind of specific ideal performance; Also can pass through from the spinning of plurality of raw materials liquid, thereby make to deposit formation dressing containing the fiber of heterogeneity simultaneously, the dressing of formation has also just comprised the fiber of different materials.Electrostatic spinning nano fiber has special structure and performance, as the fibre weight of: formation is light, good penetrability, specific area is large, porosity is high, the connectedness of internal voids is good, easily combine with nano level chemical substance or functional materials etc., and its filter efficiency is improved greatly than conventional filtration material.
