Measuring the efficacy of textile samples already treated for arm test

The novel evaluation of the repellency generated by innovative textiles already incor-

porated with nanotechnology use of some repellents against Aedes egypti Linnaeus in lab

conditions carried out at Anastasia Mosquito Control District of St. Johns County 120 EOC

Drive, St. Augustine, Florida, USA, with the following objectives:

a. Perform the best approaches for the evaluation of incorporated nano- and micro-

particles of mosquito repellent in textile

b. Carry out lab tests, according to standard recommended procedure for the evaluation

of the provided protection of 12 different impregnated fabrics

c. Determine mathematically, the measure of protection and duration of protection pro-

vided by single samples

d. Elaboration of the information results from the test results

e. Observe the consideration on efficacy performances of materials used; both textiles

and products

A set of 11 cotton fabric samples of 30 x 40 cm were previously prepared in the Faculty

of Textile Technology, University of Zagreb through Pad-dry laboratory with impregna-

tion baths followed by drying at 120 °C for 2 minutes. The repellents used are basically

of botanical origin: Immortelle Essential, Clove Essential oil, Repel Care® (Turmeric-

Eucalyptus) and IR3535. The use of these four basic repellents and their combination to

further products, Water-glass (Sodium Silicate) and Polyurethane were prepared to be im-

pregnated in fabrics.
