Abstract


A promising solution for the development of insecticidal and repellent fibers is the introduction of a crazing mechanism in the process of orientation extraction into polyester fibers of insecticidal and repellent substances to protect keratincontaining products from biological damage and the prevention of vector-borne diseases. The reason for this is the extremely slow release of the liquids introduced into them from crazes (insecticides from the pyrethroids class (permethrin, cypermethrin, β-cypermethrin), lavender essential oil), which stretches for many months and even years. The process of craze formation occurs more intensively in liquid media containing surfactants. The degree of insecticidal and repellent resistance of experimental PETF fibers was evaluated during operation as part of textile products.

It has been established that samples of modified fibers retain a high deterrent ability with respect to Xenopsylla cheopis (coefficient of the frightening-off action > 75.9 %) for 14 days of storage in the open air and have repellent activity.
