남녀 겨울철 패딩 재킷의 착용성 향상을 위한 설문조사 및 재킷 안감의 퀼팅 패턴 디자인 제안

Abstract

This study investigated the wearing patterns, discomfort, and improvement demands of Korean adult wearers of winter padded jackets and proposed improved inner quilting pattern designs to enhance mobility. A structured ques- tionnaire was administered to 480 respondents (240 males and 240 females) residing in the Seoul and Gyeonggi regions, all of whom had worn padded jackets during the winter of 2022–2023. The survey consisted of 84 items covering jacket usage, dissatisfaction (27 items), discomfort by activity and body region (15 items), and improvement requirements (14 items). The results revealed that while thermal insulation was generally satisfactory (mean score −0.2), discomfort during movement was frequently reported, especially when using the restroom (47.3%), sitting (35.2%), and driving (29.6%). Body areas with high discomfort included the shoulder (22.1% of males), neck (17.1% of females), and armpits (15.4% of males, 12.9% of females). Improvement priorities were highest for waterproofing (mean 4.1, Z-score 1.50), stain resistance (mean 4.0, Z-score 1.42), and mobility (mean 3.9, Relative Importance Index (RII) 4.76), particularly among females (RII 5.01). Correlation analysis showed that larger male body size was negatively associated with the demand for thermal insulation (ρ = −0.228, P < 0.01), while females with higher BMI demanded increased elasticity (ρ = 0.235, P < 0.01). On the based of these findings, a revised inner quilting pattern was designed by applying curved seam lines and segmented panels to the upper body area to reduce movement restriction. These results suggest that ergonomic modifications to the inner quilting layer can improve mobility and wearer satisfaction without altering the outer fabric or insulation material.
