Welscour-RW (Agasint Ultravon RW of ciba)

wetting agent and detergent with very good re-wetting action and extremely low foaming, for discontinuous pretreatment processes on cellulosic and their blends with synthetics.

chemical composition        synergetic preparation of special surfactants

appearance              transparent to slight hazy vis liquid

ionic nature              nonionic

ph                             7.5 

solubility in water      soluble in water

stability to alkali                       30 g/l naoh 100%

dissolving/diluting

it can be added undiluted to the application baths.  feed baths should be stirred after prolonged standing.suggested recipe examples

1.   discontinuous peroxide bleach :

                                0.5 – 3 g/l                              naoh 100%

                                0.5 – 1 ml/l                            welscour-rw

                                0.2 – 1 ml/l                            wetasin-gl                          

  2 – 10 ml/l                           h₂o₂ 50%

an addition of optical brightener is required for full white

liquor ratio                           4:1 – 20:1

temperature                        90 – 98ºc

reaction time                       20 – 60 mins

to ensure trouble free subsequent dyeing, we strongly recommend an

aftertreatment with wetasin-aln for residual peroxide neutralizing.

2.   enzymatic desizing :

0.5 – 1 ml/l                            welscour-rw

                0.5 – 2 ml/l                            enzyme

liquor ratio                           4:1 – 20:1

temperature                        60 – 90ºc

time                                       30 – 60 mins

hot rinsing

3.   acid cracking

                0.5 – 1 ml/l                            welscour-rw

                0.5 – 2 ml/l                            wetasin-ac

liquor ratio                           4:1 – 20:1

temperature                        30 – 50ºc

time                                       20 – 30 mins
