Abstract

In the study, it was investigated the effect of the three types of friction behaviour on the fibre loss tendency of the raised 3-thread fleece fabric, known as futter fabric. Face of 3-thread fabric contacted with the skin is raised for having well touch feeling and thermal comfort. The fabric is napped with the effects of the raising process. By raising, some fibres hold to the fabric at least one side, while others could be standing freely on the surface though fibre ends leave the fabric construction. During the usage of the raised fabric, the fibres standing freely on the surface could be caused some disadvantages for customers. There are not any standards that could measure the fibre loss degree from surface of raised fleece fabrics. In this experiment, three different test devices having different friction character were used and it was investigated the fibre loss degree on the rubbed surface as qualitative and quantitative approaches by using subjective evaluation and SEM analyses. In the study, the 3-thread fleece fabric, which is called 30-70-14, contain combed ring yarn (Ne 30) for the front face, %50/50 cotton/PES blended open-end yarn (Ne 14) for the back face and filament PES (70 denier) as connection, was used as specimen. The fleece fabric was dyed to black colour by using both the reactive and the disperse dyestuffs. In the study, during the test, the woven, single jersey and rib knit fabrics were chosen as adjacent fabrics in terms of friction on the raised face of the fabric. The tests were repeated at two conditions by using dry and humid adjacent fabrics because of the changeability of the friction coefficient between dry and humid surfaces. The fibre loss tests were made by martindale devices having different friction character. In these devices, beside differences of the type of friction, the test period was also accepted as test parameters. According to tests, it was seen the friction character was crucial effect on the fibre loss and the most fibre loss on the raised fabric was found at Martindale test device having sinusoidal movement. Moreover, the fibre loss at the raised fabric increased with using of humid adjacent fabrics, associated with the escalating of friction coefficient and friction time by using subjective and SEM analyses. Thus, it could be said, it must consider these three parameters while developing fibre loss performance test for raised fabric.
