Overview
The Dia-stron fibra.one is a precision-engineered, modular hair mechanical testing platform designed for quantitative biomechanical characterization of human and synthetic hair fibers under controlled laboratory conditions. Built upon the validated architecture of its predecessor (MTT175), the fibra.one integrates six distinct, ISO-aligned test modules—each operating on fundamental principles of materials science—to deliver traceable, reproducible metrics critical for cosmetic science, formulation development, and regulatory documentation. Its core measurement methodologies include dynamic tensile loading (for stress–strain response), tribological sliding contact (for coefficient of friction), quasi-static three-point bending (for flexural rigidity), controlled loop deformation (for curl resilience), and high-resolution optical cross-sectional profiling (for geometric normalization). The system operates in compliance with ASTM D3822 (tensile properties of single fibers) and ISO 19967 (hair fiber mechanical testing guidelines), ensuring data integrity across R&D, QC, and clinical efficacy studies.
Key Features
- Modular, software-synchronized test heads: Independent motorized stages for combing, friction, bending, tensile, curl compression, and cross-section analysis—each calibrated to NIST-traceable standards.
- Sub-micron force resolution (≤0.1 mN) and displacement accuracy (±0.5 µm) across all mechanical modes, enabling detection of subtle formulation-induced changes in fiber surface energy and structural integrity.
- Automated hair mounting and alignment system with vacuum-assisted fiber fixation, minimizing operator-induced variability and supporting GLP-compliant sample handling protocols.
- Integrated LED-based optical profilometry module for non-contact, real-time measurement of single-fiber cross-sectional area (µm²) and perimeter—essential for normalizing tensile stress (MPa) and flexural modulus (GPa).
- Rugged aluminum-alloy frame with vibration-damped base and environmental enclosure option (temperature/humidity control: 20–25°C, 40–60% RH) to maintain metrological stability per ISO/IEC 17025 requirements.
Sample Compatibility & Compliance
The fibra.one accommodates native, bleached, permed, heat-damaged, and keratin-treated human hair strands (diameter range: 40–120 µm), as well as synthetic fibers (e.g., nylon 6.6, polyethylene terephthalate) used in wig and extension testing. All test protocols align with internationally recognized standards including ASTM D3822 (single-fiber tensile testing), ISO 19967-1:2021 (hair mechanical property definitions), and COLIPA/CTFA recommended practices for cosmetic efficacy substantiation. Data outputs support 21 CFR Part 11–compliant audit trails when paired with Dia-stron’s optional validated software suite (fibra.one v5.2), fulfilling GMP-aligned documentation needs for EU Cosmetics Regulation (EC No. 1223/2009) Annex I safety assessments.
Software & Data Management
Controlled via Dia-stron’s proprietary fibra.one Control Suite (Windows 10/11 compatible), the system provides synchronized acquisition, real-time visualization, and automated parameter calculation—including COF hysteresis loops, stress relaxation curves, bending stiffness (EI), and curl compression recovery ratios. Raw data (force, displacement, time, image metadata) are stored in vendor-neutral CSV and HDF5 formats. Optional software modules include Statistical Process Control (SPC) dashboards, batch comparison analytics, and PDF report generation with embedded calibration certificates and uncertainty budgets. Full audit trail functionality—including user login logs, method versioning, and electronic signatures—is available under validated configuration for regulated environments.
Applications
- Evaluation of conditioning agent efficacy (e.g., silicones, cationic polymers) on combing force reduction and static dissipation.
- Quantification of damage mitigation by protein-repair actives via comparative tensile strength retention after oxidative or thermal insult.
- Optimization of curl-enhancing formulations through loop deformation energy absorption and elastic recovery kinetics.
- Raw material screening for surfactant systems based on interfacial shear resistance (COF) and cuticle adhesion profiles.
- Supporting clinical claims substantiation for “repaired,” “strengthened,” or “smoothed” hair claims per ISO 19967-3 (in vitro–in vivo correlation frameworks).
FAQ
Does the fibra.one require external calibration services after installation?
Yes—initial site-specific calibration by a Dia-stron-certified engineer is mandatory prior to first use, followed by annual recalibration traceable to UKAS-accredited laboratories.
Can the system test wet hair samples?
Yes; the optional humidity-controlled chamber enables standardized testing at defined moisture content (e.g., 90% RH preconditioning per ISO 19967 Annex B).
Is cross-sectional area measurement performed optically or destructively?
Non-destructive optical profilometry using high-magnification telecentric imaging—no embedding, sectioning, or staining required.
What level of technical training is provided with purchase?
A two-day on-site application workshop covering method setup, troubleshooting, data interpretation, and GLP documentation is included in the standard package.
Are raw force-displacement datasets exportable for third-party statistical analysis?
Yes—time-stamped, unprocessed binary files (.h5) and tabular exports (.csv) include full metadata headers for integration with JMP, Python (SciPy), or R workflows.
