The demand for hygienic nonwovens has increased, especially since 2020. As expected, the market for nonwovens showed an increase during the COVID-19 outbreak, especially in the medical and hygienic nonwovens sector. The aim of this study is to analyse the influence of the permeability properties of hygienic nonwovens that have been mechanically, chemically, and thermally bonded. Hygienic nonwovens are lightweight (from 20 to 120 g/m), produced by carding (roller carding), and are bonded using three different bonding processes (mechanical, thermal, and chemical). Hygienic nonwovens are intended for protective clothing in hospitals. For the experimental part, the seven different nonwovens used for hygienic purposes were produced using the dry laying process. The samples were produced in Tosama, a factory for sanitary supplies. The research results show that the nonwoven bonding processes have a significant influence on the structural, mechanical, and permeability properties.
对卫生非织造布的需求有所增加，尤其是自2020年以来。正如预期的那样，在新冠疫情爆发期间，非织造布市场呈现增长态势，特别是在医用和卫生非织造布领域。本研究的目的是分析经机械、化学和热粘合的卫生非织造布透气性能的影响。卫生非织造布重量轻（20至120克/平方米），通过梳理（罗拉梳理）生产，并使用三种不同的粘合工艺（机械、热和化学）进行粘合。卫生非织造布用于医院的防护服。在实验部分，使用干法成网工艺生产了七种用于卫生目的的不同非织造布。样品在卫生用品工厂托萨马生产。研究结果表明，非织造布的粘合工艺对其结构、机械和透气性能有重大影响。
