Optimisation of Process Parameters in Flocked Fabric Production to Eliminate the Non-Recovery Problem of Bent Fibres in Flock

Abstract

This study was focused on the elimination of defects due to the non-recovery of bent fibres in flock. For this reason, it was aimed to shorten the recovery time of bent fibres in flock as much as possible by optimising selected process parameters in flocked fabric production. For this aim; the diameter of flock fibre, the flock type, paste type, foam density, presetting, dyeing machine type, finishing treatment type, amount of treatment (finishing chemical), use of the brake mechanism during packing the fabric, and tension during winding were changed in two levels and their effects were investigated statistically. As a result of pareto analysis and statistical evaluations, among the many parameters that may affect this problem, the type of finishing process and presetting were found to have a critical effect. According to the experimental results, it was concluded that the recovery time of bent fibres in flocked fabrics could be significantly shortened if the flocked fabrics are not preset and silicone softener is applied during finishing treatments.
