  • IntroductionQE7Textile 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.QE7Textile Testing Instruments, Testing Equipment Manufacturer
