An Attachment to the Constant Rate of Elongation Tester for Estimating Surface Irregularities of Fabrics

Abstract

Fabric surface irregularities are measured using a novel attachment to a constant rate of elongation tester. The number of peaks and amplitude of the stick-slip traces correspond to the number and height of surface asperities on fabrics, respectively. Fabrics that yield more peaks and lower amplitude pulses are judged smoother than those with fewer peaks and higher amplitudes.

Surface roughness properties of polyester woven fabrics after abrasion

“…Geometrical roughness signals only the upper and the lower limits of thickness variation of fabric (Vassiliadis & Provatidis, 2004). Generally, there are two kinds of irregularities -systematic variation arising from uniform fabric structures, such as cord or ribs, and random variation caused by uneven threads or thread spacing (Ajayi, 1994).…”

Woven Fabrics Surface Quantification

“…For contact measurements the height variation (as thickness meter) or measurement of force needed for tracking the blade on the textile surface is applied (Ajayi, 1992(Ajayi, , 1994Militký  Bajzík, 2001, 2004. Contacts less measurements are usually based on the image analysis of fabric surfaces (Militký  Bleša, 2008).…”

Assessment of the effect of fabric constructional parameters on surface roughness of wool fabrics

“…The geometrical roughness characteristics of the fabrics provide information on their structural characteristics (Militky & Mazal, 2007). In general, there are two kinds of irregularities -a systematic variation arising from uniform fabric structures such as cord or ribs, and random variations caused by uneven threads or thread spacing (Ajayi, 1994).…”

“…A considerable amount of work has been done (Ajayi, 1994;Amirbayat & Alagha, 1996;Kang, Kim, Sul, Youn, & Chung, 2005;Na & Pourdeyhimi, 1995;Stylios & Sotomi, 1993;Vassiliadis & Provatidis, 2004;Xu & Reed, 1995) by many researchers to evaluate fabric surface roughness precisely. A systematic increase in fabric construction (threads per cm) increases frictional resistance but fabric surface becomes smoother.…”

“…The surface profile images showed that F3 and F9 samples had higher amplitude pulses and lower peaks than the samples of F6 and F12, respectively. Fabrics containing more peaks and lower amplitude pulses are judged to be smoother than those with fewer peaks and higher amplitudes (Ajayi, 1994). Therefore, fabrics of F3 and F9 were rougher than the fabrics of F6 and F12.…”
