  • IntroductionuFJTextile Testing Instruments, Testing Equipment Manufacturer
    In China, the national mandatory standard quot;national textile products basic safety technical specificationsquot; GB18401-2003, with effect from 1 January 2006 to enforcement, clearly defined the safety requirements of formaldehyde and other harmful substances in textile products. January 1, 2010 from the implementation of a number of national standards for clothing and textiles: quot;woven student servicequot; GB / T23328-2009, quot;male suit, coatquot; GB / T2664-2009, quot;female suit, coatquot; GB / T2665- 2009, quot;trousersquot; GB / T2666-2009, quot;tiequot; GB / T23314-2009, etc., also clearly put forward the restrictions of the formaldehyde content.uFJTextile Testing Instruments, Testing Equipment Manufacturer

    ApplicationuFJTextile Testing Instruments, Testing Equipment Manufacturer
    Textile formaldehyde content tester is used to determinate the formaldehyde content in the various textiles, clothing fabrics, often using water extraction method to prepare formaldehyde solution, and then after the color reaction with the Nessler reagent, the software can be tested out the formaldehyde content in textiles.uFJTextile Testing Instruments, Testing Equipment Manufacturer
