Textile performance, mechanics mechanical behavior

Traditional snrface treatments (Hatch, 1993) are often limited because laundering, or even normal use of the treated garment, may cause removal of the active agents. The use of chemically bound reagents on the fiber may also have a negative influence if restrictions at the binding site alter the mechanical behavior of the fiber. Modification at air-fabric and fluid-fabric interfaces is of particular relevance to textile chemistry because many performance characteristics are critically dependent on the behavior of this region. 

Researchers have examined the creep and creep recovery of textile fibers extensively (13-21). For example, Hunt and Darlington (16, 17) studied the effects of temperature, humidity, and previous thermal history on the creep properties of Nylon 6,6. They were able to explain the shift in creep curves with changes in temperature and humidity. Lead-erman (19) studied the time dependence of creep at different temperatures and humidities. Shifts in creep curves due to changes in temperature and humidity were explained with simple equations and convenient shift factors. Morton and Hearle (21) also examined the dependence of fiber creep on temperature and humidity. Meredith (20) studied many mechanical properties, including creep of several generic fiber types. Phenomenological theory of linear viscoelasticity of semicrystalline polymers has been tested with creep measurements performed on textile fibers (18). From these works one can readily appreciate that creep behavior is affected by many factors on both practical and theoretical levels.
