PERIQUEST SDL d.c. can be used in a wide variety of applications which need high soil suspension capacity and detergency, 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 SDL d.c. contains sequestering and complexing substances and has superior calcium and iron binding and dispersing properties while having only a total phosphorous content below 1.0 %.
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 SDL d.c. avoids water glass deposits during cold pad-batch process. Despite its complexing components, PERIQUEST SDL d.c. does not affect dyeing processes using metal containing dyes.
PERIQUEST SDL d.c. has a capacity of binding calcium at pH 10 of 200 mg calcium per g PERIQUEST SDL d.c., determined by boiling method.
The capacity of binding iron at pH 10 is 660 mg iron (III) per g PERIQUEST SDL d.c.
