PERIQUEST APL can be used for a wide variety of applications where high soil suspension capacity and detergency are important, for example in washing and scouring of cotton articles, in dyeing cotton with reactive dyes and in soaping of reactive, vat and sulfur dyestuffs.
Additionally, the removability of cotton accompanying substances is improved.
PERIQUEST APL contains sequestering and complexing substances and has superior calcium and iron binding and dispersing properties having only a total phosphorous content below 0.5 %.
The product is an excellent dispersing agent, it increases the detergency and the capacity of baths to keep removed soil in dispersion. This is of particular significance for short bath ratio systems. The dispersing effect serves to displace and keep in solution fibre accompanying substances, preparations and unfixed dyestuffs.
PERIQUEST APL is able to avoid water glass deposits during cold pad-batch process. Despite its complexing components, PERIQUEST APL does not affect dyeing processes using metal containing dyes.
PERIQUEST APL has a capacity of binding calcium at pH 10 of 50 mg calcium per g PERIQUEST APL, determined by boiling method.
The capacity of binding iron at pH 10 is 330 mg iron (III) per g PERIQUEST APL.
