Abstract
In this work, softeners obtained from various companies were applied to the polyamide6.6/polyurethane fabrics which are used in sportswear industry using impregnation and exhaustion methods; water vapor permeability were determined for humidity control, air permeability and capillarity tests of these fabrics were studied. In addition, the wool hydrolysate obtained from the waste wool was also applied to these fabrics by using exhaustion method and the fabric properties were compared. In order to investigate the washing resistance of the process, experiments were performed with 1% and 3% potassium aluminum sulfate KAl(SO₄)2 and aluminum sulfate Al2(SO4) under the same conditions. The chemical and morphological surface properties of the fabrics were examined by using X-ray photoelectron spectroscopy (XPS). It was observed that the capillarity, water vapor and air permeability, and handle values of fabrics treated with wool hydrolysate were better and more resistant to consecutive washings than the fabrics treated with commercial recipes. Furthermore, this process did not have a side effect on the color difference and whiteness values of the fabrics treated with wool hydrolysate. Thus, an example of sustainable, economical and environmental study was done.

IntroductionSports activities have become a hobby and lifestyle for many people, since the importance of healthy life is known and the quality of life has increased
The aim of this study is to obtain the hydrolysate from wool fibers, which were left in the carpet industry but waiting in the warehouse as waste with the decrease in production, and the hydrolysate obtained was used instead of commercial finishing bath of the polyamide6.6/polyurethane fabrics which are used in sportswear industry in Turkey
The capillarity of the fabrics was evaluated with the capillarity test method according to DIN 53924, water vapor permeability was measured according to ASTM E96-B and air permeability of the fabrics was measured by the Textest FX 3300 model Air Permeability Tester according to ASTM D737–04
Summary
Sports activities have become a hobby and lifestyle for many people, since the importance of healthy life is known and the quality of life has increased. Sports activities have become a necessity for today’s people who want to get away from excessive work and overwhelming business of urban life. For this reason, the interest in sportswear has increased. With the development of Humidity Sensors technical textiles, it is possible to have comfort during the highly intense sports activity and under different climate conditions. The measurement of how humid is a textile material is of great importance as well For such measurement of humidity traditional testing methods and recently developed sensors with different techniques – such as inkjet printing, carbon nanotubes, coating technology, stamp transfer, electrospinning and dip coating-can be used [3, 4]. Humidity control is widely carried out in many sectors dominating the daily life, such as agriculture, chemistry, food, health, pharmacy and automation
