Roughness and frictional properties of cotton and polyester woven fabrics
The roughness and frictional properties of cotton and polyester fabrics and relationship between these properties have been investigated and compared. Two sets of test samples comprising nine cotton and twelve polyester fabrics have been woven by systematically changing parameters such as weave type, weft setting and linear density of weft yarn. The fabric roughness measurements are conducted by using a new surface roughness tester for textile applications and the fabric friction measurements are performed with a friction attachment adaptable to a tensile tester. All the results are statistically evaluated in relation to the structural parameters of the test fabrics by using multivariate variance analyses. The relationship between roughness and frictional properties is examined by correlation analyses. For all the test fabrics, it can be noted that an increase in weft setting causes decrease in fabric roughness values for every weave type and this tendency is in accordance with the fabric friction results. When the relationships between the frictional and roughness values are examined, statistically significant and high correlations are determined for both of the cotton and polyester fabrics.
A Study on Frictional Characteristics of Woven Fabrics
Autex Research Journal, 2005
We have examined the fabric-to-metal surface and fabric-to-fabric frictional characteristics (in both warp and weft directions) of a series of fabrics containing 100% polyester, 100% viscose, and P/C & P/V blends with different blend proportions. It has been observed that the normal load and the frictional force follow a logarithmic relationship for all the fabrics. The nature of fabric friction is characterised by different parameters such as the F/N ratio, and the values of n, k and k/n. Fabric-to-metal friction is found to be less sensitive to fabric morphology and rubbing direction, whereas fabric-to-fabric friction is highly sensitive to these factors. Fabric friction has been affected by many factors such as the type of fibre, type of blend, blend proportion, yarn structure, fabric structure, crimp and crimp height, compressibility, etc. In P/C and P/V blended fabrics, the frictional force increases as the cellulose fibre component increases.

Frictional characteristics of woven fabrics can determine smoothness and softness values of the fabric. Moreover different environmental conditions can leads to change the properties of the weaves. In this paper, we studied the effect of temperature and relative humidity variations on the frictional properties of cotton and polyester fabrics. Plain woven fabrics were produced with polyester warp yarn and two different weft yarns (cotton and polyester). Each fabric was examined in various temperatures and relative humilities; then the frictional forces measurement was carried out on the fabrics in warp over warp direction. The results show that there is a statistically significant difference between the frictional parameters. This difference relates to the type of fiber material (weft yarns), temperature, and relative humidity. In addition, the data reveal that cotton fabrics have more static and kinetic forces than polyester fabrics in all environmental conditions. Moreover, polyest...
Frictional characteristics of woven suiting and shirting fabrics
Indian Journal of Fibre & …, 2007
Frictional characteristics of woven shirting and suiting fabrics with different blends and constructional parameters have been studied. Fabric-to-metal surface and fabric-to-fabric frictional characteristics in both warp-warp and weft-weft directions have also been studied. It is observed that the normal load and the frictional force follow the logarithmic relationship for all the fabrics. The nature of fabric friction has been characterized by different parameters, like ratio of frictional force to normal load, friction index, friction parameter and their ratio. Fabric-to-metal friction is found to be less sensitive to fabric morphology and rubbing direction, whereas the fabric-to-fabric friction is highly sensitive to these factors. Fabric-to-fabric friction has been affected by lot of factors, like type of fibre, type of blend, yarn structure, fabric structure, crimp, compressibility, etc. For all the fabrics, the kinetic friction is always lower than the static friction at different levels of normal load and the F/N ratio reduces consistently with the increase in normal pressure.
REVIEW ON MEASUREMENT AND ANALYSIS OF FRICTION ON TEXTILES
Surface texture of organisms attracts more and more interests of researchers. On one hand, the surface texture of various organisms is crucial for their adaptation to the natural environment. On the other hand, numerous excellent tribological properties of the nature inspire people to design mechanical structures and surface textures that could increase or reduce friction to be used in industries. It is the surface property of the fibre when two solid surfaces slide against each other. When we talk about fiber friction then it is very necessary because it is the force that holds together the fibre in a spun yarn and the interlacing threads in a fabric. It is the surface property of the fibers when two solid surfaces slide against each other. For example if we rub silk fabric with itself or any other type of material static charge and heat energy is produced due to fiber friction. Frictional properties of fabrics are determined by yarn friction and fabric structure. The effects of fabric structure on fabric friction have been evaluated by varying weaves, type of knits, and orientation of fibres in nonwovens. The frictional resistances within a yarn (inter-fibre friction) and between yarns (inter-yarn friction) influence fabric friction, fabric bending rigidity, fabric strength, creasing, abrasion resistance, tear resistance, and fabric hand and comfort-even though the quantitative measurement of the magnitude of effects of friction on other properties is likely to be difficult. Friction theories adopted for textiles explain that the friction is affected by their surface properties and their bulk properties. The term " skin friction " refers to the friction between in vivo human skin and an arbitrary contact material. Skin friction involves the interaction of the skin and the contact material, and consequently it depends on the properties of the skin, the contact material and its properties, the parameters of the contact between the materials and the environment surrounding the materials. Skin friction research is actually on the interface between tribology, materials science, dermatology, Product development and rehabilitation medicine.
Effect of Abrasion Resistance on the Woven Fabric and its Weaves
International Journal of Sciences: Basic and Applied Research, 2020
From yarns to fibers to fabric, a finished garment goes through various challenges to meet our requirements. One of the major factors that affect a woven fabric is ‘Abrasion Resistance’. Abrasion is basically the mechanical deterioration of fabric components by rubbing them against another surface. It ultimately results in the loss of the fabrics’ performance and its appearance. This paper shall deal with the various aspects of a woven fabric with respect to abrasion resistance, its tests and various experiments and the effect it has on the weave of the fabric.

Investigation of frictional impact on polyester yarn during knitting
Industria Textila, 2021
The usage of polyester (PET) in fabrication is increasing day by day due to its properties, ease of physical and chemical modification. The aim of this work is to understand the effect of temperature on Polyester (PET) during knitting. For checking the rise of temperature Infrared (IR) camera is used. Microscopic images are used for studying the effect of temperature on fibre/yarn structure. Morphological analysis is also done by X-ray diffraction (XRD) which shows disturbance of polymeric chains, causing change in crystal size due to elevated temperature. The beads formation and filament breakage are clearly seen in images. Due to this knitting fault, shade variation after dyeing occurred. It is concluded that structural morphology of polyester yarn changes due to friction of yarn with knitting machine parts. Fabric appearance and fabric quality also disturbed which leads to rejections and high losses.

Friction and wear characteristics of general engineering materials have been studied extensively in the past few decades. However, just a few papers reported on tribological features of silk fabrics. In this particular work, Thai silk fabric abrasive wear behaviour characteristics were investigated. The influences of silk fabric wear factors or cause variables such as the applied load, speed, and grain size of abrasive media were evaluated.
Fibres and Textiles in Eastern Europe
Fancy yarns with colour and/or structure effects are often used in clothing fabrics. These yarns give decorativeness and improve the appearance of a garment. However, fancy yarns can change the end-use properties of a fabric. Therefore, the influence of the use of fancy yarns of different structure in clothing fabrics on such end-use properties of these fabrics as abrasion resistance and mass is analysed in this article. The influence of fancy yarn structure, raw material and fabric weave on the above-mentioned properties of fabrics with fancy yarns was established during the investigation, in which the influence of the abovementioned parameters of yarns and fabric on the abrasion resistance and mass of fabrics with fancy yarns was estimated.
