Lanasol on Cotton, Wool and Fleece Fabrics (English)
Abstract [en]

A new type of natural, antimicrobial, biocompatible agent is presented. Lanasol--a brominated cyclic compound that can be extracted from red sea algae and occurs naturally was applied onto the three most commonly available fabrics: cotton, wool and fleece. Samples of the fabrics were tested for a series of properties such Antibacterial effectiveness, durability to laundering and flammability.


The treated fabric surface and the Lanasol percentage present at the surface of the fabric were evaluated by performing SEM, IR and Density Archimedes. The antimicrobial activity of the coated fibres against fungi Fussarium, was assessed using qualitative Agar diffusion test.


The Lanasol treated samples displayed very good antimicrobial properties compared to the untreated control samples.  It was observes that antibacterial effectives increased significantly with higher Lanasols solutions of 10% compared to 2,5%. Antibacterial properties remained effective after 10 washes but decreased visibly after 20 washes.  Anti-flammability properties were strongest in unwashed samples with considerable ignition time differences to the untreated control samples.


The results obtained from the current study demonstrate that Lanasol, which has previously not been tested for textile durability, has significant potential as a new antibacterial agent. This concept opens the door to further research into the increasing the antimicrobials properties as well as enhancing the success of commercial application of Lanasol for textile treatment.
