Dispersing agent for dyeings with vat, disperse and naphthol dyes
PERIGEN ASP is applied as dispersing agent for dyeings of cotton with vat and naphthol dyes as well as for the dyeing of polyester, polyamide and their blends with disperse dyes.
PERIGEN ASP is used as dispersing agent for stripping of cationic fixing agents.
PERIGEN ASP can be applied for afterclearing deep shades on fibre blends of acrylic with wool and cellulosics.
PERIGEN ASP is a highly effective dispersing agent for vat, disperse and naphthol dyes. It shows no wetting or washing properties and does not retard vat and disperse dyes.
PERIGEN ASP improves the stability of dye baths of vat dyes avoiding precipitations of dyes. It is applied as dispersing agent for dyeings of polyester at high temperature. It keeps its dispersing properties even at temperatures above 120 °C and avoids aggregation of dyestuff remaining in the dye bath during cooling down.
Also in jig or pad dyeings agglomerations of dyestuffs are avoided. After steaming PERIGEN ASP relieves removing dyes not having been fixed.
Due to its anionic character PERIGEN ASP shows affinity to cationic dyes and therefore, it is well suitable for post washing of acrylic/wool and acrylic/cellulose blends.
At acid pH value PERIGEN ASP shows certain fibre affinity to wool and polyamide.
