The keywords focus on the integration of particles into fibrous structures and the manufacturing processes required to stabilize them. Solving the loss or uneven distribution of active particles within a matrix ensures consistent product performance and material integrity.

The keywords highlight 'fast-wetting' and 'deterrent agent' integration in fibrous structures. This indicates the primary technical bottleneck is the insufficient speed of fluid uptake or wetting in multi-element fiber matrices.

The inclusion of surfactants in natural polymer matrices typically addresses the high surface tension and poor melt-flow or spinning characteristics of natural polymers. Solving this prevents fiber breakage and non-uniformity during high-speed manufacturing.
