AI Technical Summary
Existing nonwoven fabrics used for pouched products face challenges in maintaining strength and integrity due to degradation from the contents, particularly in biodegradable pouches, which are susceptible to reduced bonding and material integrity when exposed to substances like flavorings and solvents.
A nonwoven fabric comprising a chemically bonded web of staple fibers with a non-fibrous binder, such as polybutylene succinate or polyurethane, having specific Hansen solubility parameters, is used to enhance strength and stability, with a binder content of 30-50 wt% and a fabric density of 140-170 g/mm, ensuring a relative energy difference with the pouch contents exceeds 0.8.
The solution provides enhanced strength and stability to the nonwoven fabric, preventing degradation from pouch contents and maintaining integrity, suitable for biodegradable pouches used in oral products.
