In many fields, it is today important to determine in detail the surface quality of materials. Well beyond only roughness, it is necessary to characterize texture and the properties related to friction. In order to meet this need, a patented method named Modalsens is under development within the LPMT (Laboratoire de Physique et de Mécanique Textiles -UMR CNRS 7189). This method is based on the analysis of the vibratory behavior of a fine blade in dynamic contact with surface being tested. The modes of vibration of the blade provide information where roughness, texture, friction, adhesion, and compressibility are mixed. In order to characterize surface quality in detail, it is necessary to divide these various characteristics and to connect them to specificities of measured materials. This work consists of an experimental approach on the basis of varied fibrous materials (paper, non-woven materials, textiles) selected according to their surface conditions (textures) and their transverse properties (compressibility). Modalsens is then compared with reference apparatus Kawabata Evaluation System (KES) used for textiles metrology. A modeling of the dynamic contact has been developed to study the divergences between the methods of measurement to identify new parameters for a better characterization of surfaces and to identify the mechanical behaviors of fibrous asperity in shearing and transverse compression. Thus, both transverse and shearing properties, roughness, and friction will be measured and compared based on Modalsens results. with a sensor. The spectrum and fields of investigation in this area are very broad; textiles can vary greatly according to their structure, the materials which constitute them and the types of treatments (physicochemical or thermo-mechanical) that they have undergone during their manufacturing process. In practice, it is very difficult, even impossible, to know the exact conditions of each stage of manufacture of a textile. It is thus even more difficult to know the influence of these stages on the surface quality of materials. It is therefore necessary to have a global vision of the problem; here we will examine a fibrous surface as a global structure on which friction is governed by mechanical behaviors of asperities and surface pollutants. This study aims to address the following questions: How can friction on a textile on a compressible fibrous material be characterized? Which types of interactions occur during such friction? In order to place this study on a sound basis, we will review the fundamental aspects of the characterization of the coefficient of friction. We will then look at examples of studies intended to characterize friction on textiles. These two reviews will make it possible to define essential mechanical and physical parameters that have a role during friction on fibrous materials. Moreover, as the interactions of friction are often at the origin of vibratory phenomena, we will illustrate this through the description of a fundamental phenomenon: the stick-slip.Foll...

“…Studies investigating dry fabric frictions can be found in the textile scientific community, [33][34][35][36][37][38][39][40][41][42] and are among the most relevant over the past few years. However, the yarns are different from those used in composite reinforcements, in terms of mechanical properties and geometry.…”

“…The larger the difference between the static and dynamic friction, the more regular the stick-slip will be (see Figure 2). This relative difference in static and dynamic friction has been encountered as a good indicator for subjectively ranking the tactile sensation of fibres (Ro Èder, 1953) and fabrics (Ajayi, 1992a, Ajayi et al, 1995. Increasing the speed of sliding will abruptly terminate the stick-slip at a certain characteristic velocity (Derjaguin et al, 1957).…”

“…Increasing the speed of sliding will abruptly terminate the stick-slip at a certain characteristic velocity (Derjaguin et al, 1957). Stick-slip motion has now been successfully used by several researchers (Ajayi, 1992b;Ajayi et al, 1995;Hosseini Ravandi et al, 1994) in relating the frictional characteristics of fabric to the topographic structure of its surface. Ajayi (1992b) showed that there was a positive relationship between the yarn crown height and the peak to peak values of the slip traces, and that the number of peaks correlated well with the yarn density or number of cords.…”

A novel technique to measure stick‐slip in fabric

Stick‐slip is characterised by an intermittent movement when two materials are sliding across each other at very low speeds. This paper describes a new method of measuring stick‐slip on knitted and woven fabrics when sliding over non‐fibrous materials. The technique uses emitter‐receiver pairs arranged at regular intervals along the full length of the fabric panel, which each visualise the irregular movement of sticking and sliding. It is found that an extensible knitted fabric exhibits either shear or micro‐slip during the stick phase, before the actual gross slip movement.
