Abstract

Purpose

The purpose of this study is to introduce a novel approach for seam pucker analysis based on wave shape parameters.

Design/methodology/approach

In this method the uneven wavy curve along the puckered seam line was put into a deconvolution process and broken into several simple Gaussian curves using residual mathematical analysis method. First puckered samples with five different grades were produced and scanned by laser triangulated technology. After implementation of deconvolution method, the key geometrical parameters of the decomposed waves such as number of waves and their shape parameters like wave's area, amplitude and wave length were extracted. In addition, an objective method was developed and five indexes were introduced.

Findings

Analysis showed that there is a high linear relation with high correlation between all pucker indexes and subjective pucker evaluation.

Originality/value

The goal of this research was to analyse the five grades of seam puckered samples and extract the basic structural parameters to solidify the characteristic of each puckered grade, in order to exclude the influence of human perception.
