Textile formaldehyde content tester
The Textile Formaldehyde Content Tester is a precision instrument designed to determine formaldehyde levels in textiles, including fabrics, garments, and finished textile products. Using chemical extraction and colorimetric methods (e.g., Nessler reagent reaction), it accurately quantifies free and hydrolyzed formaldehyde content. The tester ensures compliance with national and international textile safety standards and supports high-throughput testing, data storage, and automated wavelength calibration for reliable and repeatable results.
Application Scenarios
(1) Textile manufacturing and processing: testing raw fabrics, dyed and finished fabrics, and functional textiles for formaldehyde content
(2) Garment production lines: ensuring finished apparel, uniforms, bedding, and home textiles meet formaldehyde safety standards
(3) Textile laboratories: R&D of safe, low-formaldehyde fabrics, functional fabrics, and smart textiles
(4) Inspection and testing agencies: verifying compliance of cotton, polyester, wool, silk, blended fabrics, and technical textiles
(5) Educational institutions: teaching textile chemistry, fabric safety, and quality control procedures
(6) Comparative evaluation: assessing fabrics and garments from different suppliers or production batches for formaldehyde levels
(7) QC in specialized textiles: testing waterproof/breathable laminates, coated fabrics, and flame-retardant materials
