The non-contact color measuring instrument
The Non-Contact Color Measuring Instrument is a high-precision device designed for color measurement, management, and analysis of textile products. Using advanced LED multi-spectral light sources and imaging technology, it enables accurate, non-contact measurement of fabrics, yarns, and finished textile items. The system supports color comparison, clustering analysis, and data sharing in digital or image form, making it ideal for quality control, R&D, and production monitoring in textile industries.
Application
The instrument is widely used in:
(1) Textile printing and dyeing: measuring colors of fleece fabrics, lace, patterns, plush, hats, buttons, and accessories.
(2) Quality control: ensuring color consistency and compliance with standards in manufacturing processes.
(3) R&D: evaluating new textile dyes and color treatments.
(4) Color management: analyzing color clustering, color difference, and tolerances for production optimization.
(5) Textile testing laboratories: providing accurate and reproducible measurements for certification and research.
(6) Apparel and fashion: assessing colorfastness, shade, and uniformity across different textile materials.
(7) Educational institutions: training students in colorimetry, color matching, and textile quality evaluation.
Standards
The instrument is compliant with key international and national standards, including:
(1) ISO 105 A11 – Determination of colorfastness to staining and color change
(2) ASTM D1925 – Standard test method for lightness of paper, textiles, and other materials
(3) ASTM E313 – Standard practice for calculation of yellowness and whiteness indices
(4) CIE 15:2004 – Colorimetry standards for measurement and color spaces
(5) ISO 7724-1/-3 – Color measurement methods for textiles and materials
(6) DIN 6174 – Color difference determination in textile materials
