THE EFFECT OF PHYTIC ACID ON FLAME RESISTANCE IN LEATHER PRODUCTION
Project no. 28475 · Status: Kapanmış (Yayın bekleniyor) · 2023
Summary
<p>In the literature, it is stated that the use of leather materials in areas with functional requirements is increasing, but studies on flame retardancy in the leather industry are still limited. It is stated that all the studies in the field of flame retardancy for leather, textile and other materials have been carried out on the substitution of these substances with environmentally friendly substances due to the damages of existing flame retardants to human and environmental health. It was seen that phytic acid obtained from sources such as beans and oil seeds gave positive results in wool with protein structure and there was no study on the use of this substance in the industry for leather with protein structure.</p><p>In the present study, it was aimed to investigate the effect of phosphorus-containing phytic acid and modified phytic acid, a bio-based substance that has recently attracted interest in flame retardant applications, on the flame retardancy and other properties of leather. For this purpose, phytic acid was obtained and it was planned to apply both direct and modified phytic acid to the leather in leather applications. For the modification, the esterification reaction previously performed to increase the strength of phytic acid in wool will be used and the synthesized substance will be characterized. Chrome tanned leathers will be provided for leather applications. In the retanning phase of one of the trials, one of which is the control group, no flame retardant will be used, while in the retanning phase of the other trials; commercial flame retardant, phytic acid and modified phytic acid will be used in different ratios. The flame retardant properties, shrinkage temperatures and physical test results of the finished leathers will be analyzed comparatively.</p><p>As a project output, it is aimed to obtain finished leather using an environmentally friendly flame retardant that has not been tried in the leather industry, to reveal the operability of phytic acid in leather and the properties of the finished leather obtained. </p>
