Children’s cloth face mask sizing and digital fit analysis: method development
Mona Maher,Jenny Leigh Du Puis,Katarina Goodge,Margaret Frey,Heeju Terry Park,Fatma Baytar 한국의류학회 2024 Fashion and Textiles Vol.11 No.1
There is a necessity to use digital data and tools when developing children’s products. The present study was designed to provide digital methods to guide product development and problem-solving when using 3D body scans and face mask simulations for 6-year-olds. First, key facial measurements were evaluated to better understand the variables that might affect face mask sizing for children for the selected age group. Then the findings were used to optimize the size and fit of a cloth face mask design. Next, the fit of the digital, optimized face mask design was tested on 44 head scans from Size North America by using subjective and objective fit assessment techniques. Study findings suggested that width and length-related measurements are critical for children’s face masks. Body mass index (BMI) and ethnicity were also found to be the main factors for identifying size ranges in the selected age group. As BMIs increase, face mask sizes should increase. Additionally, the results indicated a need to use a larger database of children of all ethnicities to design an inclusive facemask that would provide a comfortable and protective fit for different facial proportions. Although the results cannot be generalized due to the case study approach of the present research and its focus on methods development, they can provide manufacturers, designers, and researchers with guidelines on how to develop proper sizing and use digital data to conduct functional fit analysis for facemasks.

Cloth face mask fit and function for children part two: Material Selection
Katarina Goodge,Jenny Leigh Du Puis,Mona Maher,Margaret W. Frey,Fatma Baytar,Heeju Park 한국의류학회 2022 Fashion and Textiles Vol.9 No.1
The second component of this three-paper series studying cloth face masks for children ages 4 to 6 years old concentrates on optimizing aerosol capture and air permeability through fabric selection. Material choices were evaluated in two modes: Flat Filter (FF) and Head Form (HF). FF isolates material factors while HF simulates the performance of the constructed masks on a 3D printed child head form. In FF mode, higher fltration efciency correlated to lower air permeability in both reusable commercial and experimental face masks regardless of fber contents, fabric structures, and number of layers. Our prototype face mask developed in design exploration successfully captured 37±12% of 0.3 μm, 87±3% of 0.5 μm, and 87±2% of 1.0 μm particles while maintaining good air permeability, moisture capture, and aerosolized salt capture in HF mode. Sealing masks to minimize outward leakage reduced particle capture up to 64%. Particle leakage data captured at the eye level of the head form illuminated the synergy between mask design, material choice, and ft.

Cloth face mask fit and function for children part one: design exploration
Jenny Leigh Du Puis,Lauren Forstenhausler,Katarina Goodge,Mona Maher,Margaret Frey,Fatma Baytar,Huiju Park 한국의류학회 2022 Fashion and Textiles Vol.9 No.1
Commercially available children’s cloth masks range widely in material type and fabric structures, methods of construction, layering, and shape, and there is a lack of sizing systems, anthropometric data or guidelines specifcally targeting the ft assessment and design of cloth face masks for children 4-6 years old. To better identify and understand the cloth face mask ft and functional needs of children ages 4-6 years old, the researchers embarked on interdisciplinary in-depth study to investigate commercial market oferings of children’s face masks, identify consumer perspectives, and explore mask design improvements through design research. By triangulating results from survey feedback, commercial market content analysis, and wear trial observations, the researchers were able to identify important design criteria that can be used in the improvement of children’s cloth face mask design: size, comfort, dexterity, movement, and thermal comfort. These criteria were used to iteratively develop new mask prototypes involving a 3D printed head form, traditional sewing and hand patternmaking skills, and the creation of multiple mask versions to explore the design criteria listed above. The designs were interpreted through Bye’s (2010) Problem-Based Design Research (PBDR) framework, which identifes common design research practices in the feld on a spectrum and situates PBDR as a process centered on a problem as impetus for design through which artifacts are developed.
