        formaldehyde particularly strong anti-corrosion ability, the use of leather should be involved in the process of formaldehyde in resin finishing. In fabric production, in order to achieve wrinkle, shrinkproof effect, or keep printing, dyeing durability, or improve the feel, all need to add formaldehyde in auxiliary. Especially for textile leather textile, leather fade easily, color additives can improve the use of formaldehyde in leather. However, high concentrations of formaldehyde has a great harm to the human body.
    Huake experiment Co. Ltd. according to the test system for the detection of textile American Standard GB and AATCC112-2003 development of the content of formaldehyde release,. The system has accurate detection, simple operation, dedicated to the export enterprise quality assurance escort.
A, test principle of
in a closed container with a certain amount of water, will have been weighing textile samples by some method to make the suspension in the water. Then the closed container is placed in the constant temperature oven, the specified temperature and time to maintain fabric, formaldehyde release is absorbed by the water become to be checked, for color reaction with the chromogenic reagent solution treatment, according to the color liquid in a spectrophotometer values calculated from the formaldehyde content. The formaldehyde content in
the standards applied to contain formaldehyde in leather, especially through chemical reagents containing formaldehyde treated leather. The test also provides a method for accelerated storage quantity, and the use of an analytical method to determine the amount of formaldehyde release in the accelerated storage condition.
three, product characteristics,
1     the operation is simple, use convenient, affordable  .
2,     operating cycle is shortened, for the enterprise to save a lot of extra time.
3,     detection with no limit on the number of proper maintenance, unlimited detection, long service life.
4,       leading technology: the use of sealed container method, this method is more accurate than the water extraction method, and more by the international market recognition.
5,     data comparison: do compared and verified with the third party testing institutions detection data, the effective control of harmful substances exceed the standard risk.
four, the reference standard of  
AATCC  112-2003  Determination of formaldehyde in textiles to release
GB/T  sealed container method; 6529-2008  " " leather; standard atmosphere for conditioning and testing
GB/T  6682-2008  "analysis laboratory water standard specification and test method"
five, applicable customer types: printing and dyeing factory, weaving factory, garment factory, leather factory enterprise user.
six, after sale service:
1, spectrophotometer and other major equipment warranty for 1 years free maintenance, repair.
2, the company provides the establishment of standard curve, maintenance and other services, to ensure the accuracy of the test data. Professional and technical engineers sent
3, the company face to face technical staff training (until the church).
