Abstract

Understanding the performance and behavior of garment leathers provides valuable inputs for the design and production of leather garments. The drape is one of the important properties associated with garment fitness quality and appeal. This study aims to show how the independent variables flexural rigidity and thickness affect the dependent variable drapability. Nowadays, studies on the drape of garment leathers are scarce. In this work, the drape coefficient (DC) was measured for sheep garment leather, which influences the garment drapability, such as flexural rigidity in the range of 9.2 to 22 and thickness in the range of 0.64 to 0.96. The average DC was calculated in the range of 47.35 to 69.9% for the selected sheep leathers from four samples. The drapability of the garment leather was determined using the DC. Flexural rigidity and thickness have been shown to have a considerable influence on the DC, while they do bear a significant relationship to the DC. The results of this study can be used as an elementary tool for leather selection of appropriate materials for garments.

Highlights

Leathers for garments can be manufactured from almost all types of raw stock [1].the widely used raw material is sheepskins for their histological characteristics [2]
The garment leather drape should become between the accepted ranges 30–80, where drape coefficient (DC) below 30 is very limp leather and better to use for very small goods
The DC largely depends upon the flexural rigidity and thickness of the leather

Summary

Introduction

Leathers for garments can be manufactured from almost all types of raw stock [1].the widely used raw material is sheepskins for their histological characteristics [2]. The drape is the most significant garment feature, since it contributes to wear comfort [6] This feature refers to the leather’s capacity to fall in a similar manner to textile and conform to the body’s shape when worn [7]. It is an inherent and essential quality for any leather to be called garment leather [8]. Leather drapability is a morphological property that occurs when leather is hung down for gravity reasons It is one of the essential indicators when measuring close-fitting clothing [6]. A circular sample with a specific area is placed on a sample clamping plate, with their centers overlapping, causing the drape sample to droop along with the circular plate due to gravity [13]
