6631 is a completely new multi-elements material and has new linear chemical structure. It is macro luster and smoothing agent. In alkali condition, it has better resistance to high temperature than common silicone softener. In high temperature, it has better stability than common silicone softener on resistance to anionic.
6631 is used for cotton knitted fabric, cotton woven fabric, printing fabric, denim fabric, polyester  and other blended fabric and impart fabric excellent smoothing hand and improve its luster as like silk. 

Advantage:
High stability (can work well on high alkali(pH 9-10) and good anti shear and high temperature)
Is compatible with anionic
Improve fabric luster and smoothing fell and high resilience.
Super low yellowing, so can be used for white/light color fabric
Is widely used for padding, exhaustion and over flow spray machine.

Appearance:
           Appearance:  transparent  liquid
           Ionicity:  nonionic/weak cationic
           pH Value:  5.0-6.0(1% aqueous solution)
           Solubility:  easily diluted at any ratio. 

Usage:
           Firstly dilute it 1:2~3, then adjust its pH value to 5-6.
           Dosage: 
                 Padding: after dilution at 1:2~3 by water, 40g/L-80g/L.
                 Exhaustion: after dilution at 1:2~3 by water, 4-8% o.w.f.
