Rubbing Fastness Improver LH-F2250
Rubbing fastness improver LH-F2250
RSI (rubbing fastness improver)LH-F2250 is one kind of special high polymer of cationic chemical compound, suitable for after dyeing deep color fix of cellulose fiber and its blend, can improve fabric’s dry & wet fastness well.
Properties
• Can improve dry, wet fastness of pure cotton, polyester, T/R, T/C
• No impact to washing fastness, perspiration fastness and hand feel
Basic Character
Appearance: slightly yellowish liquid
Ion state: weakly cationic
pH(1%):4.0 ~ 5.0
Soluble: easy dissolve in warm water
Application
• Cotton fiber and its blended treated by Sulphur, reactive or direct dyes,
fixing after dyeing
• Fixing after printing of T/R & T/C
Method
LH-F2250 20-30g/L, one dip one pad, dry by over 100℃
Remark
• When apply for sulphur dyes, it is better soaping with surfactant first, if necessary, can use ammonia (0.1 ~ 0.2 g/L), to avoid solution PH change to impact the fixing effect.
• When LH-F2250 use with other chemical, better to check the compatible first.
• After take the goods, should ensure the package cover closed.
Package
125kg plastic drum
Storage
Half year in cool place
