An optimization study on the sol-gel process to obtain multifunctional denim fabrics

This study introduces the results of an optimization study on sol-gel application conditions applied to obtain multifunctional (water repellent/flame retardant) denim fabrics using the Design Expert software and a step-by-step approach. The study started by obtaining the proper drying/condensation parameters and water-repellent additive amount, followed by determining the proper co-precursor and flame-retardant additive amount, and finally covering the mechanical tests of the samples to determine if the results would be applicable for industrial purposes. The results indicate that it is possible to approach the optimum process conditions applicable to industrial-scale working conditions to produce denim fabrics with high levels of water repellency and flame retardant performance.
