Abstract

The invention discloses a non-destructive method for testing the content of formaldehyde in a textile. The method comprises the following steps: filling an absorption solution into equipment provided by the invention and fixing a textile to be detected on the equipment; then making the state of the absorption solution to be in a steam-liquid drop-steam ceaseless cycle from top to bottom by a condensing device and other outer equipment (such as a heating device) provided by the invention; eluting and absorbing released formaldehyde on the textile and determining an absorbance value by a spectrophotometer and through an acetylacetone developing process; and calculating the content of formaldehyde in the textile according to a standard formaldehyde working curve.

Description

technical field [0001] The invention relates to a textile detection technology, in particular to a method for testing the non-destructive formaldehyde content of textiles. Background technique [0002] Formaldehyde, commonly known as formaldehyde, is a colorless gas with a pungent and pungent smell, which can irritate the eyes and nose of the human body; and formaldehyde is highly toxic. It ranks second in the list of toxic chemicals controlled in my country. , has been determined by the World Health Organization as carcinogenic and teratogenic substances, is a recognized source of allergies, and is a potential strong mutagen. [0003] Formaldehyde is a cytoplasmic poison, which can directly act on amino, sulfhydryl and carboxyl groups to generate methine derivatives, thereby destroying body proteins and enzymes, causing irreversible coagulation and necrosis of tissue cells; after inhalation of high concentrations of formaldehyde, there may be Severe irritation of the respir...
