Corresponding measurement-based patternmaking method for leggings using three-dimensional body scanning technology

Abstract

Based on 3D body scanning, this study developed the corresponding measurement-based patternmaking (CMP) method for leggings that could systematically provide an excellent fit and control tightness for different body parts. The CMP method for leggings was qualitatively validated by comparing the fit suitability of the produced leggings prototypes through a wear test. The results suggest that the CMP method is an option to design leggings with outstanding suitability in terms of appearance satisfaction, size satisfaction, compression satisfaction, usefulness in movement, ease of movement, ease in donning and doffing for different body parts. In particular, the graduated application percentage (GAP) provided an advantage in usefulness in movement, while the fixed application percentage (FAP) showed an advantage in ease in donning and doffing. As such, this study suggests selecting the CMP method of the application percentage (AP) depending on the purpose of use. This study demonstrated that the proposed method ensured validity in directly implementing a leggings pattern with 3D body scanning and body measurement alone.

Corresponding measurement-based patternmaking method for customized gloves to support smart wearables

“…If future developers want to produce gloves with a higher fit level, they should use stretch materials with greater elongation than the materials used in this study to find ways to reduce patterns that reflect the material’s elongation. As reported in studies on elastic materials in tight-fitting clothing, 16,35,36 the rate of pattern reduction or material elongation application between the weft and warp direction should be operated differently in gloves. Few in-depth studies have been conducted on the application rate of pattern reduction or material elongation on gloves production.…”

“…The framework of the entire process for customized gloves was the same as the CMP method for customized leggings: Step 1, 3D human body figure acquisition and editing by 3D body scanning; Step 2, 3D grid creation with horizontal and longitudinal baselines; Step 3, body surface length measurement divided by the 3D grid; Step 4, transition of a body surface length measurement to a 2D block pattern; and Step 5, 2D block pattern reduction to obtain the final leggings pattern. 16 Due to the structural specificity of the hand, which differs from the lower body, the patternmaking process of the customized glove prototype differed from the method used for leggings.…”

“…The study reviewed the process of devising the CMP method for customized gloves according to the rules of the CMP method for customized leggings, 16 which was the first attempt to directly implement an apparel pattern using only 3D human body scanning and human shape measurement. The CMP method for customized gloves involved the following steps: Step 1, 3D human figure acquisition and editing by hand scanning; Step 2, 3D grid creation with horizontal, longitudinal, and bias baselines; Step 3, divide the hand surface length measurement by the 3D grid; and Step 4, transition of a hand surface length measurement to a 2D block pattern.…”

“…Kim and Choi 16 devised a corresponding measurement-based patternmaking (CMP) method for leggings through which a pattern can be created that corresponds directly to human body parts without determining the body shape type, with a 3D human body figure obtained by human scanning. The possibility of producing leggings with a good fit for women with average body dimensions using this method has been verified.…”

“…After making the pattern for a customized glove prototype and producing it according to a design protocol, this study conducted a wear test. In the process of manufacturing customized glove prototypes that consider functionality and usability, gloves were required to have a protocol adjusted from the rules of the preceding method, the CMP method for customized leggings, 16 due to the structural specificity of the hand. Accordingly, this study proposed a guideline for customized gloves’ patternmaking to help future developers.…”
