Cautions:
1.If suspension liquid is foundprecipitated and separated, just shake it before use, which does not affect theuse effect.
2.Please note that use this product within its yellow spot, i.e. paddyeing ≤5g/l,dip dyeing ≤0.8%(o.w.f). If use this product beyond its yellow spot, it will be easy to becomeyellow.
