20250171939 · 2025-05-29 ·

Disclosed is a method of producing a rigid package material from textile waste. The method comprises mechanically shredding the textile waste into fibres, the textile waste comprising synthetic textile; blending the fibres with a binder; arranging the blended fibres into a nonwoven web; needle punching the nonwoven web to form a nonwoven felt; and pressing the nonwoven felt thermomechanically to obtain the rigid package material.

FILTRATION MEMBER FOR ANTIVIRAL AIR FILTER

A filtration member for an antiviral air filter, having an upstream fiber layer for which the contact angle with respect to water is 60 or less, and a downstream fiber layer for which the contact angle with respect to water is 90 or greater, wherein the filtration member has an antiviral agent and a dispersant either on the upstream fiber layer or on the upstream-fiber-layer-side surface of the downstream fiber layer, and the solid fraction mass ratio of the antiviral agent and the dispersant ((mass of solid fraction of antiviral agent)/(mass of solid fraction of dispersant)) is 0.20-5.0.

The present invention provides a filtration member for an antiviral air filter in which the dust collection performance of the filter is ensured, and the amount of antiviral agent adhering to the filter is reduced and a high virus inactivation rate is achieved irrespective of changes in the environment around the filter.
