摘要

High density barrier fabrics for applications as filtration and multi-use OR textiles, structurally possess continuous pore channels between the yarns (meso-pores), which provide potential openings for contaminated particles and liquids. The size of these pores can be reduced by high density weaving, but an increased fabric density will lead to a stiffening of the fabric, reducing its physiological properties and wearing comfort. A partial and targeted reduction of the size of the meso-pores by means of a particle finishing, including the simultaneous formation of a porous structure within the pores, can increase the barrier effect of the fabric without negatively affecting its physiological characteristics. An additional functionalization of the particle shell with polyacrylic acid (PAA), and a matching activation of the fabric surface with atmospheric pressure plasma ensure a fixed connection of the particles and their binding to the fiber surface. The resulting porous structure leads to the creation of a new microstructure ensuring the retention of physiological parameters, such as the resistance to water vapor permeability.
