Influence of electron radiation on the physical and mechanical properties of a nonwoven fabric made using Spunlace technology

Abstract

The effect of electron radiation on the physical and mechanical properties of Sontara nonwoven fabric produced using spunlace technology has been studied. The initial raw material for the manufacture of materials using this technology, as a rule, are viscose, polyester, polypropylene and cellulose fibers. Such nonwovens are highly breathable and are therefore used in disposable surgical gowns and suits. Since radiation can be used to sterilize disposable surgical gowns, it is important to assess the resistance to ionizing radiation. It was found that the Sontara brand material is resistant to the effects of ionizing radiation - the physical and mechanical characteristics of the material (breaking load and relative elongation) in the longitudinal and transverse directions of the web do not significantly change when irradiated with absorbed doses up to 60 kGy. It should also be noted that a cloth with a basis weight of 68 g/m2 has a significant smell of strength after radiation sterilization.

Plasma modification physical and mechanical properties of nonwoven materials of medical masks

“…Nonwoven materials are raw materials for the production of disposable medical products: clothes, underwear, masks [1,2]. In the context of the coronavirus pandemic and the impossibility of quickly producing a large number of medical masks, the task of developing sterilization technologies for medical masks and respirators is relevant.…”
