- HPMC hydroxypropyl methylcellulose
- polyester polyester
- HPMC a cellulose-based binder
- PVP a vinyl-based binder
- HPMC is more stable than PVP when dissolved. Due to its high viscosity, it is not uniformly dispersed during the filter manufacturing process, and the tow adheres to the machine roll and dries, resulting in problems such as the tow breaking.
- PVP has the advantage that it has a lower viscosity compared to HPMC, so problems do not occur in the filter manufacturing process, and the TEC material can be uniformly dispersed in the lyocell tow.
- polyester has a low viscosity like PVP, but it cannot be mixed uniformly with TEC, a functional material related to phenols, so there is a limitation that it must be uniformly dispersed using a surfactant or emulsifier.
- TEC a functional material related to phenols
- a polyester binder solution was prepared by mixing a polyester binder with water, propylene glycol (PG), and ethyl alcohol (EtOH), and a PVP binder solution was prepared by mixing a PVP binder with water, PG, EtOH, and TEC.
- PG propylene glycol
- EtOH ethyl alcohol
- TEC ethyl alcohol
- layer separation occurs when mixing TEC together, making it difficult to prepare a uniform binder solution.
- PVP as an amphoteric binder, it mixes well with TEC, making it easy to prepare a binder solution.
- Cigarettes were manufactured using Lyocell filters to which the above two types of binder solutions were applied, and the phenol smoke components of each cigarette were measured and compared. The results are shown in Table 2 below.
