Currently, there is a tendency for significant increase in production and expansion of areas application nonwoven materials (NM), which are used almost all human life. Such properties NMs as hydrophilicity or hydrophobicity, air permeability, good barrier strength indicators at relative low cost allow them to be effectively medical purposes. Nonwovens use (NMMN) considered. The most important stage the final processing devices made NM radiation sterilization. influence absorbed dose type ionizing on NMMN various designs: obtained by spunlace technology, spunbond-meltblown-spunbond laminated material has been studied. As result conducted research, it was recommended: sterilize with an electron beam, control consumer from check quality products after sterilization assessing change index elongation, additionally assess – water resistance, absorption. In materials, polymers used, have correspondingly different resistance Some example, based polypropylene, degrade when exposed radiation, level technical characteristics significantly reduced. It also possible autooxidative reactions initiated occur polymers, can continue long time irradiation articles. To these sterilized devices, necessary understanding effect wide range sterilizing doses devices.
