Relation of Fiber and Fabric Properties in Durable-Press Cottons

Abstract

A cotton twill fabric was subjected to a durable-press treatment with dihydroxy dimethylol ethylene urea (Permafresh-183) of increasing severity. The mechanical properties of the fabrics and of single fibers withdrawn from the treated fabrics were evaluated and the relationships between fiber and fabric properties were analyzed. Statistically significant correlations between such important fabric properties as abrasion resistance, tear strength, tensile strength, and energy-absorbing capacity, on the one hand, and fiber mechanical properties, on the other, show conclusively that chemical treatments which alter fiber structure and properties are responsible for the modified fabric behavior. At the same time, the importance of fiber geometric arrangements in spun yarn and fabric structures, in terms of fabric properties, are pointed out. Thus, while this work has shown the functional relationships between fiber mechanical properties and fabric characteristics, careful attention must be given to fiber-fiber interactions, particularly in relation to chemical modification treatments.

The Role of Fiber Cohesion in DP Treatments of Cotton

“…conventional pad-dry-cure treatments with Permafresh 183 were carried out at The Gillette Company Research Institute and have been described previously[2]. The wet-fixation treatments were also carried out at The Gillette Company Research Institute by the usual procedure El].…”

Bulk Resilience of Native and Chemically Treated Cottons

“…Many papers in the literature describe techniques for measuring bulk resilience [1,4,6,7,8]. Resilience of a fiber mass, sometimes referred to as &dquo;hand&dquo; or &dquo;handle,&dquo; has been regarded as a property directly related to the elastic recovery of constituent fibers.…”

Wear Life of Easy-Care Cotton Fabrics

“…Literature Cited Introduction Byssinosis, a chronic in8ammatory lung dysfunction, is an important occupational disease. It is prevalent in a significant number of workers that have been exposed to prolonged inhalation or otherwise encounered long-term exposure to dust in cotton textile mills [2,3,19]. The disease is also found in susceptible workers who handle Hax and soft hemp [4,5], and perhaps sisal [ 14,16] and jute [ 1.5, 18].…”

“…However, available evidence indicates that it is diHicult to draw oonclusions on the end-use performance of a fabric based on studies on abrasion alone [7,18]. Likewise, correlation analyses carried out to understand the relationship between the fabric performance with the several other physical properties also have not helped in unambiguously identifying the physical properties that will correlate with the end-use performance of the fabric under all conditions [5,13,19].…”
