Further Insights into the Fatigue of Hair Fibres through Statistical Analysis and Relevance to Hair Care Applications
Abstract
The study of fatigue is a well-established discipline within the field of material science.Understanding the fatigue of materialswhen subjected to repeated load cycles providesinsightful knowledge about fractureandfailuremechanisms.Such information hasbecomeessentialinthedevelopmentand manufacture of products ranging from aeroplanes to car tyres. The fatigue behaviour of fibres is well studied,encompassing bothtextileandtechnicalfibres.Themeritoffatiguetestinghasbeen recognised within the cosmetics industry and in recentyears there has been an increasingusageof cyclic fatigue testing within the hair care sector.Duringdailygroomingpractisesand routines,hairfibresontheheadareexposedtorepeated stresses which contribute to fibre fatigue. Although the applied stresses are much lower than what is requiredtobreakthehairinasingleapplication,overtime,thisleadstoanaccumulationof stress and eventual failure of the fibre.To study this, a repeated stress or strain can be applied to singlehairfibres until they break. Use of Dia-Stron CYC802 modulesin conjunction with anautomated platform allows for high-throughput cyclic fatigue testing of hair fibres. The aim of many cyclic fatigue studies is to make comparisons between different types of damage or to assess the performance of treatments. The number of cycles to break foreach test groupcan be fitted usingeither a Kaplan Meier Estimatora 2-parameter Weibull distribution.InordertoascertainaconfidencefortheestimatedWeibullparameters,itisimperativetocalculate theconfidence intervals[1, 2].ThiscanbeachievedbyapplyingaBootstrapmethodtogenerate confidenceboundsfortheexperimentaldata[3].Also,basedonthedistributionobtainedforthe Weibullparameters,statisticalcomparisonsbetweengroupscanbeconductedusing parametricor non-parametric methodssuch as Kolmogorov Smirnov tests[4]. These statistical analysis techniques,will be illustrated with examples relevant to the hair care applications.References[1]F.Islam,S.
