Abstract:

Research has been conducted in the Institute of Chemical Fibres with the aim of preparing synthetic fibres which can inhibit the growth of house dust mites thus limiting or eliminating a cause of allergy. The physical-mechanical properties of anti-mite polypropylene fibres and needle-punched nonwovens containing such fibres are presented. The anti-mite activity was tested according to the French standard NF G 39-011. A nonwoven containing modified polypropylene staple fibres was used to prepare bedding inserts, which were then tested with regard to their anti-allergic usefulness. It was found that the material causes a very distinct reduction in mite guanine concentration, and the bedding insert largely contributes to a much more comfortable feeling for the patients. The anti-mite nonwoven in the form of bedding inserts was approved by the Office of Registration for Medicinal Products, Medical Devices and Biocidal Products, as well as by the Ministry of Health.
