textile formaldehyde tester is used to test formaldehyde content in various fabrics.
textiles formaldehyde tester fine-grained textiles are extracted in a water bath at 40 ° C for a period of time. Formaldehyde extracted from the fabric is absorbed by water and the extract is developed with acetylacetone (yellow). The yellow compound has a visible Selective absorption, so the use of colorimetric analysis method can be measured in the textile formaldehyde formaldehyde content of samples tested.

principle: textile formaldehyde tester of formaldehyde in the air reacts with the phenol reagent to form the oxazine. The oxazine is oxidized in the acid solution by high-iron ions to blue-green compounds. According to the color depth,
