4. Emulsifier of the negative ionic type.
5. Violet Fluorescent colour cast.
6. Nor-ionic-type.
7. Stable chemical properties such as resistance to acid & alkali, etc.
finishing agents.
8. Be mixed by the negative or non-ionic surface active agents, dyeing, pigment, painting and resin
Be not mixed by the positive matter as indicated above.
9. Common uses : Steeping: 2-3% (OWF)Padding: 20-30g/L
10. Temperature and baking time: 160-190°C/3-5min.
11. Stable period of the emulsifier: a half year.
( if the emulsificr bad sedimentation and is separated in the solution, please use mixing method into
uniformily, than to use.)
Process:
Padding process:
1. T/C (65/35) blend fabrics technological processes:
Scaming --- Singeing-- Scouring --Bleaching-- Heat Setting -- Mercerizing -- Dacron fabrics
brightening-- Rebleaching -- Heat stenter - Cotton fabrics brighting - Finishing.
2. T/C (65/35) bleach fabrics pad-dyeing formula: Fluorwhiter DT 25g/L.
