Dyeings of polyester with disperse dyes, dyeings of polyester-cotton with disperse respectively vat dyes, dyeings of polyamide with acid dyes.
Sewing threads and embroidery yarns, if the lubrication takes place by exhaustion in process water with high electrolyte content (conductivity above > 400 μS/cm).
PERISTAL SPA is an organic buffer which controls the pH value in the range of 4 – 6 when dyeing polyester with disperse dyes or polyamide with acid dyes.
The product has an excellent dispersing power for disperse dyes which are kept in finest distribution and the levelness of dyeings, therefore, is supported by PERISTAL SPA.
PERISTAL SPA does not loose its effect at high temperature and it effectively avoids an aggregation of remaining dyestuff particles when cooling down. A retarding of disperse dyes does not occur.
Furthermore PERISTAL SPA can be used to improve the stick-slip behaviour of sewing threads and embroidery yarns.
PERISTAL SPA is free of detergents and it does not cause any foam.
