Investigation of the Fabric Construction of the Effect on Pilling and Abrasion in Yarn Dyed Cotton Fabrics
For this study, yarn dyed cotton woven fabrics were produced in three different yarn counts and three different patterns, then pre-treatment processes were applied to these fabrics. The physical properties and pilling and mass losses with abrasion performance properties of these fabrics were determined experimentaly according to relevant standarts. The obtained results were evaluated and fabric construction of the effect on pilling and abrasion was analyzed.
The effect of wet abrasive wear on the tensile properties of cotton and polyester-cotton fabrics
The tensile properties of cotton and polyester-cotton woven fabrics have been analyzed in terms of the breaking load, breaking extension, breaking elongation, and elongation at 1 kg (1% full-scale-deflexion (FSD)) using the Instron Tensile Tester, Model 1026. Changes in tensile properties of the woves fabrics as a consequence of wear using the Accelerotor Abrasion Tester in wet conditions are illustrated. The tensile properties before and after abrasion and the effect of abrasion damage on the tensile properties were determined. The Spearman rank correlation coefficient was used to determine the interrelationship between the tensile properties and percentage loss in weight. Relationships between the tensile properties, mass, thickness, density, and specific volume of these fabrics before abrasion are also reported. A significant positive correlation (at 5% and 1% levels) was obtained between breaking load, breaking extension, and breaking elongation, and between breaking extension and breaking elongation in both wet and damp abrasion. Determination of a simple paired t-test showed that there was no significant difference between the unabraded and abraded fabrics (wet and damp), or between wet and damp abraded fabrics at the 95% confidence interval with respect to tensile properties.
Studies in Wear Life of Normal- and Special-Finished Woven Cotton Fabrics
A statistically designed service wear trial of normal- and special-finished shirts for school boys was undertaken under controlled conditions of wearing and laundering, with the object of providing a basis for predictions of service wear performance from results of laboratory tests. The tear and abrasion performance were separated and the former is reported in this paper. The concept of "consistent significance" of a physical property has been introduced as a necessary basis for its choice as a predictor of tear performance in service, on the grounds that predictions made on the initial levels of physical properties, unless confirmed on the basis of their changing levels during progressive use in service, could be misleading. In the present study, the tensile strength is found to be consistently significant and, hence, the dominant functional fabric property actually involved in explaining tear performance in service.
