摘要： Cellulose acetate fibers can be modified to have physical imperfections and then incorporated into cigarette filter plugs as filtering materials. Cellulose acetate fiber modification can be achieved by etching with a gas phase etchant or a liquid phase etchant comprising hydrogen peroxide. Modification of cellulose acetate fibers may be performed at various stages during the manufacture of cigarette filter plugs. Furthermore, cigarette filter plugs containing modified cellulose acetate fibers can also have spaced apart slits along the length of the cigarette filter plugs.
摘要翻译：醋酸纤维素纤维可以被修改为具有物理缺陷，然后作为过滤材料并入香烟过滤嘴塞中。乙酸纤维素纤维改性可以通过用气相蚀刻剂或包含过氧化氢的液相蚀刻剂进行蚀刻来实现。醋酸纤维素纤维的改性可以在卷烟过滤嘴制造过程中的各个阶段进行。此外，包含改性醋酸纤维素纤维的香烟过滤嘴也可以沿着香烟过滤嘴的长度具有间隔开的狭缝。

摘要： Provided are a method and apparatus for making a cigarette filter assembly 10 for potentially reducing particle breakthrough. The method includes forming a lofty porous network of charge retaining polymer fibers 14 by mechanical, chemical or thermal bonding of the fibers, wrapping the lofty porous network in a cylindrical or tubular shape with optional mediating filter fibers 32 in a filter paper to form a filter plug while maintaining the lofty structure. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop. The apparatus handles the lofty media with minimal crushing, for example, by spacing apart delivery rolls equipped with protrusions to punch, push, and/or pull the lofty media ahead for high speed operation.
