The influence of mechanical effects on coated textile hydrophobic properties

In this study, the influence of cycle fatigue and abrasion on hydrophobicity of coated textile was investigated. For this purpose, six coated materials were chosen that are used for protective clothing. The studies carried out show that the abrasion of the surface of the same nature allows project behaviour of product during exploitation. Micro-cracks, which damage the protective layer material, can occur in flex place after bending or tensile stress. Cycle fabric fatigue that imitates bending, flexing and stretching was performed using equipment IPK500, 9000, 12000 and 15000 cycle mode. Fabric surface abrasion was measured using equipment YGH-1, 2000, 3000, 7000, 8000, 9000 and 15000 abrasion rotations were chosen to do the test. The method of drop contact angle measuring is used to evaluate hydrophobicity. The studies show that ultimately influences on the surface roughness had abrasion of the same surfaces. According to the obtained research results the material with PU coating is the most resistant against abrasion. The material coated with PVC is also resistant against abrasion and after maximum abrasion remained hydrophobic.
