Abstract
Textile materials may exhibit an appreciable amount of creep. The creep behavior of a fabric is characterized by uniaxial creep and recovery tests. The well-known Schapery nonlinear constitutive relation is modified to make it suitable for characterizing the creep behavior of fabrics. This modified constitutive equation demonstrates that total creep recovery strain can be divided into four parts, i.e., instantaneous elastic, instantaneous plastic, viscoelastic, and viscoplastic. Theoretical discussions present the procedures and methods of determining constitutive parameters. Creep characteristics of nonwoven and woven fabrics are tested and constitutive parameters are determined.
