Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile detection, in particular to an integrated detection device for formaldehyde and pH value of textiles. BACKGROUND

[0002] Formaldehyde is a common crosslinking agent for cellulose fiber resin finishing, and is widely used in pure spinning or blended products (including some silk products), thereby giving textiles the functions of shrinkage resistance, wrinkle resistance, non-ironing and easy stain removal. However, in the process of wearing or using, part of the un-crosslinked or hydrolyzed free formaldehyde in textiles with excessive formaldehyde content will be released, causing harm to human health. At present, there are mandatory provisions for the formaldehyde content on textiles in China, and the method standard for detecting the formaldehyde content of textiles is GB / T 2912.1-2009 "Determination of formaldehyde in textiles Part 1: Free and hydrolyzed formaldehyde (water extraction method)", which adopts the analysis method of ultraviolet-visible light absorption spectrophotometer (UV-VIS).

[0003] The pH value of textiles refers to the residual acid-base content in the fabric, which is generally required to be in the neutral range. It is also necessary to detect the pH value, and the harm of excessive pH value is not less than that of formaldehyde. If the surface of human skin is weakly acidic due to textiles, it will help to prevent the invasion of bacteria, and if the acid-base degree of clothing exceeds the standard, it will reduce the immunity of human skin. An intuitive manifestation is that part of the skin-sensitive group will cause skin redness or itching and cause physical discomfort if they wear clothes with excessive pH value. At present, there are mandatory provisions for the pH value of textiles in China, and the method standard for detecting the pH value of textiles is GB / T 7573-2009 "Determination of pH value of water extract of textiles", which uses a pH meter to determine the pH value in textiles.
