APPLICATION
Fluo-free WF Plus is normally applied by padding process.
Dissolving / diluting
Dilute Fluo-free WF Plus with twice the amount of cold water and add to a bath containing acetic acid.
It is recommended to adjust bath pH with 1-2 ml/l acetic acid 60 % before adding the diluted dispersion into the bath (if necessary, through a strainer or filter).
Application
Padding method
pH of the prepared bath: approx. 4.0-5.0
Pick-up: approx. 40-80%, depending on the fiber
Bath temperature: about 20-25 °C
Drying temperature: 110-130 °C
Separate curing: 5 min at 150 °C on curing machine or
Rapid curing process: 45-60 sec at 110-170°C in stages (stenter)
Required amount
30 – 100 g/l Fluo-free WF Plus

NOTES
Preparation of the goods:
In order to obtain optimum effects, the goods ready-to-be-finished must be free of residual processing chemicals such as wetting agents and dyeing auxiliaries, sizing residues, softening agents and other surface-active compounds.
To avoid impairment of the effects, mechanical treatments such as calandering, schreinering, brushing, etc. are performed after drying, i. e. before curing. Steaming and decatizing processes may be carried out after curing, as an improvement of the effects could result. Raising and emerizing processes should be carried out before the finish.
The crock fastness of disperse dyed and printed fabrics might be impaired. Preliminary trials are therefore recommended.
Further down-stream processing, such as garment washing, laminating, coating etc. of the finished fabric could impair the stain management properties. Preliminary trials are advised to ensure that the fabric performance is not impaired after such treatments.
Spray application (not product specific)
Aerosols are generated through the spraying technique that potentially may be hazardous to health. For this reason spray application can only be safely conducted if sufficient ventilation equipment is installed at the product application site which will prevent spreading of the aerosols into the workplace. An alternative would be to carry out the spraying application in a closed system.
