Abstract

In this study, the mechanical properties and preferences of natural and artificial leathers were analyzed. The leathers were classified based on mechanical properties affecting their preferences. The mechanical properties of the leathers were measured via the KES-FB system, and an expert survey was conducted to evaluate leather preference. Leathers possess different mechanical properties depending on the manufacturing process and structural characteristics. Furthermore, differences were observed in the mechanical properties of natural and artificial leather. The mechanical properties of the leathers were related to the preferences for hand and bags. Accordingly, the leather was classified into three clusters. The leathers that were preferred for hand were not preferred for bags, and those preferred for bags were not preferred for hand. Therefore, different development strategies are needed, depending on the type of leather. Natural leather for bags should be light and have good compression elasticity along with its existing mechanical properties, whereas artificial leather should be light and have improved tensile resilience.

Highlights

Advances have been made to artificial leather to make it significantly more similar to natural leather than ever before in terms of both physical properties and functionality.[1]
Higher WT was observed in artificial leathers that used tricot base fabric (P1–P5) and were light
The use of knitted fabrics of artificial leather facilitates the movement of fibers, yarns, and coating during tensile, thereby resulting in increased tensile energy

Summary

Introduction

Advances have been made to artificial leather to make it significantly more similar to natural leather than ever before in terms of both physical properties and functionality.[1] The mixed use of natural leather and artificial leather is increasing given the advantages and disadvantages of natural leather and artificial leather in terms of price and durability. In the case of sofas and car seats, the areas that touch and don’t touch the skin are composed of natural and artificial leathers, respectively. In the case of bags, trimming and straps are made of leather artificial leather is used in the body. The term “hand” refers to the sensory performance of a fabric sensed by touch and visual sense, Affiliation of the author Eui Kyung Roh was updated after the paper was first published. In a narrow sense, it refers to a feeling that is felt when a fabric is touched with a hand. In order to improve tactile comfort, mechanical properties and hand evaluation of various fiber textiles and finishes were examined.[3,4,5,6] The hand of a fashion product, Jeonbuk National University, Jeonju-si, Korea
