The problem of human being protecting against UV radiation is becoming more and more
significant from year to year and requires urgent solutions. Just UVB causes 50-90% of skin cancer and
especially affects children, adolescents and older people. Textile screens are the simplest and most
effective means to protect against the negative effects of UV radiation (UVR). Usually, white cotton and
linen fabrics are used for summer clothes. However, these materials have a low ultraviolet protective factor
(UPF ~ 5). Known developments that relate to the modification of textile materials to protect against UV
radiation, suggest the use of dense woven structures; modification with some metals oxides; the use of
UV absorbers that are derivats of harmful chemicals (for example, o-hydroxybenzophenones). But these
methods do not always provide the sufficiently level of UV protection. In our paper, the effectiveness of
vat dyes using to create textile screens for UV protection was investigated. In this study was
investigated cotton fabrics dyed with some vat dyes: turquoise, blue, yellow. UVR transmittance studies
were performed on optical spectrometer Solar SL40-2 (PSI-Line software). A high pressure discharge
lamp DRT-125 was used. As studies have shown, the most effective is a cotton textile screen, dyed with vat
blue.
Investigation of the influence of the structure of textile materials for hospital bed linen with various raw compositions on the ability to provide thermophysiological comfort during operation inhospitals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
