Relationship between Friction and Tactile Properties for Woven and Knitted Fabrics

Abstract

The relationship between friction and the tactile properties of woven and knitted fabrics was investigated. Coefficients of friction for the fabrics were measured using two devices: a previously developed Textile Friction Analyzer and the Kawabata Evaluation System FB4. The tactile properties of the fabrics were evaluated by a panel, which assessed the roughness and the prickle of textile surfaces in two different blind subjective tests. Correlation between fabric friction and subjectively perceived touch properties was found for knitted, but not for woven fabrics. In order to find out if additional parameters could have influenced the obtained relationship, textile properties such as bending, compression, basis weight, hairiness and fabric thickness were investigated. Using principal component analysis, we found that the relevant properties in the relationship between friction and the touch properties of fabrics were bending, thickness and compressibility. On the other hand, the friction results showed a lack of commonality between the friction analyzer and the Kawabata surface tester, although there seemed to be a negative correlation between the two apparatus. This was attributed to the different testing conditions such as applied load, sliding speed, contact area and material surfaces and illustrated the dependence of fabric friction properties on testing variables

A Simple, One‐Step Approach to Durable and Robust Superhydrophobic Textiles

“…Table 2 summarizes the wetting properties of a coated glass and a coated sample of PET #407 fabric before and after an abrasion test performed on a textile friction analyzer (TFA). [28] The normal load used for these experiments corresponds to approximately 150% of the contact pressure that occurs when a person touches and rubs a fabric with the fingers [29] and is comparable to the pressure at the skin-mattress interface for a bedridden person. [28] After 1 450 abrasion cycles the textile sample still shows a low WSA, whereas no WSA is measurable on the glass sample.…”

“…Nevertheless, stringent conclusions regarding the influence of the higher COF of the coated versus the uncoated PET fabric on the tactile properties (haptics) could not be drawn. The tactile properties of a textile fabric are a result of various structural, mechanical, and surface parameters, [29] the friction properties being only one of them, and a detailed haptic analysis would require comprehensive subjective sensory assessments by human test subjects.…”

Tribology of Skin: Review and Analysis of Experimental Results for the Friction Coefficient of Human Skin

“…The friction and surface properties of materials and objects are known to be essential for their tactile properties. It is possible to assess friction and tactile properties in human subject tests, but instrumental tribological measurements are an efficient alternative, providing objective and more reproducible results (no inter-and intra-subject variations) [30][31][32][33]. This is why there are attempts to use mechanical skin models in combination with tribological tests where mechanical contacts between skin and external materials are simulated close to practical conditions [34][35][36][37][38][39][40].…”

Investigation into the Effect of Extended Laundering on the KES-F Mechanical Properties of an Easy Care Treated Cotton Fabric

“…The increased number of raisings caused the suede to have a soft and smooth surface and improved perception of luxuriousness [27]. The hand properties of woven and knitted fabrics were investigated using the KES-F and frictional analyser tests and the KES-F results indicate that there is a good correlation between friction and tactile properties for knitted fabrics but not for woven fabrics [28]. Furthermore the Kawabata system was applied on investigation on the effects of fabric movements in front-loading washers on hand properties.…”
