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.
Comparison of Physical Properties of Fabrics Woven from Open-End and Ring Spun Yarns
It is well established that open-end yarns are different from ring yarns; in particular OE yarns are weaker and more bulky in spite of the higher twist levels used. The introduction of these yarns into woven fabric affects the structure and the characteristics of the fabrics. The fabric structure traps non-load bearing fibers and thus gives increases in fabric strength and decreases in fabric extensibility. Crimp levels are altered which affect the initial modulus and the breaking extension of the fabric. This and the different yarn characteristics lead to considerable difference in tear strength. In the cases, of both ring and OE fabrics, the looser the structure, the worse the pilling performance and the better the tear performance. Compromises have to be made according to end-use. The changes in structure alter the topography of the fabric which affects the wear behavior. The changes in structure also affect the crease resistance and flexural rigidity characteristics of the fabrics. Thus the differences in the yarn structure play a distinct part in determining the final nature of the fabric.
Appraisal of Woven Fabric Performance
This work evaluates the performance of 100% cotton woven fabrics. We have ex amined abrasion resistance, diverse mechanical properties (compression and flexion), and certain aesthetic properties (handle, i.e., stiffness, smoothness, and softness). Changes in the properties of a fabric as a consequence of wear are illustrated; wear is a laboratory action involving some method of abrasion such as an Accelerotor on either dry or damp fabrics. In addition, we consider some aspects of the physical and mechanical properties of woven fabrics in which changes in weight, thickness, stiffness, air permeability, and compression are used as criteria to assess damage caused by frictional abrasion. The results show that weight loss may be small as a result of short periods of accelerated wear, and changes in other physical properties may be large, particularly compression, flexion, and air permeability. The differences between worn and unworn fabrics can be detected subjectively by touch. Changes occur in fabric properties as a result of incremental wear. Weight per square meter, coercive couple, and flexural rigidity show consistent decreases with increasing abrasion time at a fairly uniform rate. Thickness, air permeability, lateral air permeability, and compression show inconsistent increases with increasing abrasion time at non-uniform rates.
