Assessment of Crease Recovery Values of Textile Fabrics by Different Instruments

Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">A comparative evaluation of the crease recovery angles of textile fabrics measured using three different crease recovery testers, viz. Monsanto, Metrimpex and Shirley, has been made to assess the recovery characteristics of textile fabrics in the true sense. The effect of different factors like load, loading/relaxation period, sample size crease length and spacer (particularly used in the Monsanto method) on the crease recovery values has also been studied. It has been observed that the evaluation of commercial samples cannot be made by the Monsanto method, as the measured angles in this case do not represent the true values. However, both the Metrimpex and Shirley testers do furnish equivalent values according to the basic physical principle of property measurement, Metrimpex tester could be used preferably, provided certain precautions are taken, as it enables measurements for more than one specimen at a time, as against the Shirley tester which can handle only one specimen. It is recommended that the standard method of determination of crease recovery values of textile fabrics should involve the formation of crease/wrinkle as per the basic physical principle without any spacer to measure the recovery values in the true sense.</span>
