Objective Evaluation of Garment Seams Using 3D Laser Scanning Technology

Abstract

This paper reports on the development of an objective method for evaluating the degree of puckering in garment seams. With this method, a garment is put on a dummy and a seam is scanned by a 3D laser scanning system. The geometric surface of the scanned seam is then processed with a 2D digital filter to obtain a pucker profile by removing the "high frequency" components due to the fabric surface texture and the "low frequency" components due to three-dimensional garment surface contours. From the pucker profile, we can derive a physical parameter, log (σ2), which is linearly related to the subjective pucker grade. From the objectively measured log (σ2), we can objectively evaluate the pucker grade of the garment seam.

The use of laser in garment manufacturing: an overview

“…Seam pucker negatively affects the garment appearance Padhye 2014b, 2015a;Nayak et al , 2013Fan and Liu 2000). There are several methods to measure seam pucker, but the conventional rating system developed by American Association of Textile Chemists and Colourists (AATCC) is mainly used.…”

“…Here, we need to find the nonnegative eigenvalues λ and eigenvectors v , satisfying the equation v C v= λ (5) Noting that all the eigenvalues lie in the span of the transformed data in the high dimensional space, the equivalent relation can be written as…”

Thermal shrinkage of fabrics used for out layer of firefighter protective clothing under flash fire

“…The technology of digital image has been widely applied in studying textile appearance in the past decades []. By using a charge coupled device camera or a scanner to obtain the fabric images, the surface roughness or the fuzzing and pilling of the fabrics could be examined .…”

“…This method, however, can only be applicable to fabrics with plain color, and to those printed fabrics with several different colors the shadows due to the fabric surface fluctuation could be concealed by the surface texture . Therefore, three‐dimensional scanners were utilized by researchers to obtain the fabric appearance in a three‐dimensional form .…”
