چکیده

The research for objectifying the handle of textile fabrics is a very important factor in the textile and garment manufacturing and retailing industries. Handle is influenced by mechanical properties of textile fabrics and the surface roughness. The KES-F system is standard objectified method among different measurement methods. But the measurement of surface roughness applied the KES-F which is contact method disturbs an accurate measurement for analysis of tactile perception. Hence we measure the surface roughness of textile fabrics without deformation by a non-contact method applied the laser displacement sensor with a resolution of 1 μm and a accuracy of 0.01% and high precisely controlled linear motor for translated at constant speed. Since the textile fabrics are woven and knitted with various colored yarn and its surface treated with chemical treatment to make luster, we analyze the effect of color and luster in order to reduce the optical errors. And the results of surface roughness of various textile fabrics compared with the surface characteristic values (MIU, MMD) measured by KES-F system. The data is controlled on computer and executed FFT by using MATLAB for obtain roughness, the mean values and mean deviation from thirty plain and twill woven fabrics for men’s suit in winter. We will present the comparison between the surface roughnesses of textile fabrics measured by a non-contact method with the subjective adjective tactile expression to understand the tactile perception.

Can you see what you feel? Color and folding properties affect visual-tactile material discrimination of fabrics.

Humans can often estimate tactile properties of objects from vision alone. For example, during online shopping, we can often infer material properties of clothing from images and judge how the material would feel against our skin. What visual information is important for tactile perception? Previous studies in material perception have focused on measuring surface appearance, such as gloss and r...

Predicting Tactile Fabric Comfort from Mechanical and Handfeel Properties Using Regression Analysis

In this paper we explore complex relationships between mechanical and sensory properties of fabrics, and the perceived tactile comfort. Mechanical properties, measured objectively by Kawabata Evaluation System for Fabrics (KES-FB), and handfeel properties, measured subjectively by sensory expert panel, are related to the tactile comfort of fabrics using statistical regression approaches. A univ...

Kinetic Friction of Sport Fabrics on Snow

After falls, skiers or snowboarders often slide on the slope and may collide with obstacles. Thus, the skier’s friction on snow is an important factor to reduce incidence and severity of impact injuries. The purpose of this study was to measure snow friction of different fabrics of ski garments with respect to roughness, speed, and contact pressure. Three types of fabrics were investigated: a c...

Surface Modification of Polyester Fabrics with Vinyltriethoxysilane

Surface modification of polyester fabrics was studied aiming at improving the water repellency property. Vinyltriethoxysilane (VTES) was employed as surface modifying agent. Prior to application, VTES was prepared in aqueous emulsion using cetyltrimethylammoniun bromide (CTAB) as an emulsifying agent. The application of VTES emulsion was carried out using a padder and followed by curing at 150C...

Estimation of Roughness Parameters of A Surface Using Different Image Enhancement Techniques (TECHNICAL NOTE)

Surface roughness measurement is widely used to estimate the quality of the product during manufacturing processes. It has a great importance in manufacturing fields such as ceramic tiles, glass, and iron. Many are using surface profile-meter with a contact stylus to measure the surface roughness of work piece. In the stylus method, a stylus is moved along the surface and the vertical movement ...
