Eco-friendly filter for smoking article having disintegrability

A smoking article comprising:

• a smoking material portion;
• and
• a smoking article filter disposed downstream of the smoking material portion,
• wherein the smoking article filter includes lyocell tow including lyocell fibers and a filter portion wrapper configured to surround a filter portion,
• after three months (twelve weeks) under industrial composting conditions including a temperature of 58° C.±2° C. and a humidity of 50%±2% according to EN 13432, the smoking article filter has a disintegrability of 80% or more, and
• the disintegrability is defined by Mathematical Equation 2 below,
