RUCO®-CLEANER BAR

Reducing agent for after clearing of PES/Elastane mixtures in a cooling disperse dye bath or in an acidic fresh bath

  • Hygroscopic and sensitive to moisture
  • Should be protected with concentrated acids and oxidation agents
  • Low foaming

Field of application: Universally applicable

Chemical Basis: Preparation of special reducing materials

Ionic Character: Uncharged

Form: Powder


RUCO®-CLEANER BRC

Low foaming cleaning agent with strong migration improvement and dye binding properties for PES, PES/Elastane and PES blends dyed with HT method

  • Binds unfixed dyestuff and keeps it in the washing bath
  • Free of phthalic acid esters
  • Free of APEO and APEO derivatives
  • Should not be mixed directly with the chemicals in the polymeric structure

Field of application: Universally applicable

Chemical Basis: Preparation of special polymers and fatty alcohol ethoxylates

Ionic Character: Anionic/non-ionic

Form: Liquid


RUCORIT® RGX

Reducing agent for reduction clearing of disperse dyeings and prints; reduction agent for reductive bleaching; dyeing with sulphur dyestuffs; stripping of disperse dyeings (100 % PES); stripping of reactive dyeings; cleaning of dyeing machines

  • Stable, decomposes only under prescribed conditions of application: from 70 °C or when adding alkalis
  • Almost odourless in application
  • Provides a perfect level ground for re-dyeing in the stripping of the reactive dyed fabric
  • At elevated temperatures higher reductive potential than that of sodium dithionite (hydrosulphite)
