Date of data collection (single date, range, approximate date) Data collected between 2022-10-01 - 2023-1-01 5. Geographic location of data collection (where was data collected?): Wearable Technology Lab 322 McNeal Hall 1985 Buford Ave Saint Paul, MN 55108 6. Information about funding sources that supported the collection of the data: N/A 7. Overview of the data (abstract): Supplemental record of fabric thickness, weight, and tensile data used for compression modeling. Fabric thickness and fabric weight were averaged across 5 samples for 3 synthetic textiles in various material assemblies to use for compression modeling applications. Each row in these files represents datapoint for either a single layer (textile only), two layer (textile + silicone backed elastic) or three layer (textile + elastic + textile) sample. Samples used for material testing were cut to tensile testing specifications (200 mm by 50 mm strips) and, for two- and three-layer samples, assembled into the appropriate sample type. Fabric weight and thickness (following ASTM D1777-96, 2019) were found before testing for tensile strength (following ISO 13934-1:2013). Testing was conducted across four days with an average temperature of 21.81 C (+/- 0.58 C) and a humidity of 24.13% (+/- 2.03%). -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

File List A. Filename: fabricProperties.csv Short description: Results from testing the fabric weight and thickness for all 9 material assembly combinations. B. Filename: tensileData.csv Short description: Averaged tensile data for each textile and material assembly used for compression modeling. C. Filename: TensileSampleMerging.R Short description: R Code used for combining the five samples tensile data for each material assembly used in modeling. -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: 5 samples created for each type: single-layer of textiles, two-layer textile and silicone-backed elastic, and three-layer elastic-textile-elastic assembly. Samples were cut and created as 200mm by 50mm samples, first used for fabric weight and thickness testing, then used for breaking strength testing using a tensile testing machine. Fabric Weight: 1 measurement per sample, 5 samples per material assembly type. Fabric Thickness: 3 measurements per sample, 5 samples per material assembly type Breaking Strength (Tensile Testing): ISO 13934-1:2013 used for 5 samples per material assembly type 2. Methods for processing the data: Fabric Weight: Averaged across (5) samples Fabric Thickness: (3) measurements averaged within a sample, then across (5) samples per sample type Breaking Strength (Tensile Testing): First, data from the group of (5) samples were trimmed based on the highest minimum strain and the lowest maximum strain to ensure there is data present from all five samples at each strain measurement. After trimming, averaged force values were found for each strain grouping, at .25 mm increments. These averaged force values were converted to stress, and then used for the piecewise model-fitting 3. Instrument- or software-specific information needed to interpret the data: N/A 4. Standards and calibration information, if appropriate: Fabric Thickness: ASTM D1777-96(2019) Breaking Strength (Tensile Testing): ISO 13934-1:2013 5. Environmental/experimental conditions: Testing was done across four days, with an average temperature (eight datapoints) of 21.81 C (+ or - 0.58 C) and humidity of 24.13% (+ or - 2.03%). 6. Describe any quality-assurance procedures performed on the data: Samples were not cut from the selvage of the textile, and were cut using different course and wale yarn combinations to ensure proper manufacturing variability to reach a more accurate result. 7. People involved with sample collection, processing, analysis and/or submission: Lead researcher and advisor (authors listed). Lab manager and labmates had small involvement with initial tensile testing setup. ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: [fabricProperties.csv] ----------------------------------------- 1.
