Properties of textiles from PP fibres modified with multifunctional additives

Abstract

Goal of the research is preparation of multifunctional concentrates offering properties of: flammability reduction (FR), enhancement of UV resistance (UV) and antimicrobial finish (AMB). Basic characteristics of the prepared multifunctional concentrates used for treatment of polypropylene fibres are presented and their effectiveness against flame, UV radiation and microbes were tested. Obtained results of change of selected performance characteristics of the textiles in relation to their construction and possibilities of practical application are compared in discussion. The achieved results revealed positive effect of the developed concentrate (28/1676 type) containing FR component on reduction of time of spontaneous flame burning of the knitted fabrics by 20 seconds in comparison with the standard. Besides, reduction of strength of the modified knitted fabric by the influence of UV radiation only by 5 % in comparison with 95 % after exposition on a standard knitted fabric was achieved. Tests for antibacterial activity confirmed high degree of bacterial reduction (> 90 %) on knitted fabrics from the modified PP fibre. This way high efficiency of the multifunctional concentrate (FR and UV and AMB) 28/1676 type was confirmed.
