Investigation of 3D Woven Fabric Topography Using Laser-Scanning

Abstract

Among the different features of fabrics, surface properties play an important role, especially in the case of fabrics used near human skin. The effect of fabric on human skin in direct contact influences the sensorial comfort of clothing usage. The appropriate designing of woven fabrics from the point of view of their stiffness and surface properties can create new possibilities for their application. Particularly 3-dimensional woven fabrics of small-scale evenly distributed three-dimensionality can be applied in therapeutic clothing ensuring micro-massage. At the moment there is a lack of methods enabling the assessment of 3D woven fabrics with a textured surface from the point of view of the geometric structure of the surface. The paper presents preliminary investigations of the surface topography of 3D woven fabrics by means of a laser-scanner for precise 3D measurements.

Parameterization of Seersucker Woven Fabrics Using Laser Techniques

“…The values of the W z parameter for both kinds of strips are different. This was also stated in a preliminary investigation [15]. It is worth emphasizing that the maximum value of the W z parameter occurred in regions where the height of puckering was the highest; therefore, we can determine this value as the maximum puckering effect in a given measurement range.…”

“…This paper presents a proposal for the parameterization of a seersucker woven fabric. The scanning method is very similar to that proposed by Matusiak and Fracczak in their preliminary investigations [15], with the difference that in this paper, the geometric analysis was conducted using a point cloud rather than the previously processed scanned surface. As a result, two steps were eliminated: creation of a surface geometry, and projection of the lines onto the surface in order to measure the individual values of the parameter Wz.…”

“…To evaluate the parametric geometry of the seersucker fabric, the W z parameter proposed by Matusiak and Frącczak [15] was used. It was determined on the basis of the difference between the highest peak and the deepest valley in a given measurement range and is expressed by means of the following relationship:…”

“…Additionally, the authors defined some important parameters characterizing the surface of textile materials, such as woven, knitted, and nonwoven fabrics. [15] used laser scanning to determine the surface characteristics of seersucker woven fabrics. They analyzed seersucker fabrics with the seersucker effect in both warp and weft directions.…”

“…The authors stated that in the case of the seersucker woven fabrics, the surface measurement should contain at least one full repeat of the seersucker effect in the warp direction and one full repeat of weave in the weft direction [15]. They elaborated a preliminary proposal of a measurement method for assessment of the surface geometry of seersucker woven fabrics using laser scanning [15][16][17]. In this method, a laser scanner was used to generate the scanned point cloud representing the fabric surface and to transform the point cloud into the fabric surface simulation.…”
