AI Technical Summary

Technical Problem

Existing respiratory protective devices have issues with comfort and fit during wear, especially when the face moves, they tend to slip or shift, leading to leakage and discomfort. Furthermore, traditional designs may be heavy and not flexible enough.

Method used

The use of pleated expandable filter media, which forms a stretchable pleated structure by introducing elastic fibers or filaments between nonwoven porous meshes, enhances the fit and comfort of the media, and is combined with adsorbent materials to improve filtration efficiency.

Benefits of technology

It improves the fit and comfort of the breathing device, reduces breathing resistance, extends service life, and maintains high-efficiency filtration performance.
