In the study, it was aimed at investigation of the fibre loss performance effects of the 3-thread fleecy raised fabric. With this aim, various samples were obtained by changing the Fleecy-Yarn fibre content, the Face-yarn type, the number of Fleecy-Yarn floating, the Fleecy-Yarn pile length, and finishing process called as main parameters. After the raising process, the raising fastness (in-house term) of these fabrics were evaluated. After tests, the data were statistically analysed by variance analysis (ANOVA) to determine the effect of the main parameters on the fibre loss performance of these raised fabrics. The results showed that Fleecy-Yarn fibre content and finishing process were statistically significant. Consequently, it was determined these parameters could be considered to reach better raising fastness.

Within the scope of the study, pre-softening, raising and final softening processes were applied to 2 fleece fabrics under different conditions. The raising fastness, air permeability and bursting strength tests were performed on the samples obtained after the processes, and the effect of the process conditions on the researched performance values was examined. This paper is also detailed by statistical analysis. When the results were examined, it was seen that the best result in terms of raising fastness was the fabric with 50% waste + 50% PES back yarn. As a process, it was determined that the best result was obtained after a single passage with micro silicon pre-softening and raising at a speed of 15m / min, and then a low concentration softening process with a polyvinyl acetate-based binder and softener mixture.
