Scouring Agent 501
【Brief Introduction】
Scouring Agent 501 is a new environmental friendly and efficient pretreatment agent, which is a major change in the traditional caustic soda process. The product can avoid excessive fiber damage and reduce weight loss (3-5% less than the traditional process). After use, it can significantly increase whiteness, capillary and hydrophilicity, and improve dyeing ability and leveling ability. The product is easy to washing, can reduce the number of washing, and is simple to operate. It provides an effective way to realize economic, environmental protection and short flow pretreatment.
【Nature】
Composition : Complex of high polymer and various surfactants
Appearance : White solid grain
PH: 11.5±1（1% Aqueous solution）

【Application process】
Cotton knitting fabrics , yarn ,Bobbin yarn:
Scouring agent 501 : 2~4g/l
Wetting agent : 1—2g/l
H2O2 (27%) : 4-8g/l
NaOH or Na2CO3 : 0-1g/l (as your demands)
Bath ratio :1:10-15
Temperature：95 - 100℃ Time :50~60min
Process：Scouring Agent 501 into the cylinder for circulation → heating to 50 ~ 60 ℃ → adding H2O2 → circulating heating 130 ℃ for 15 min or 120 ℃ for 25 min or 100 ℃ for 50 ~ 60 min → liquid discharge → hot water washing (60 ℃, once) → liquid discharge → de aerator treatment for 10 ~ 15 min → dyeing
Woven Fabrics :
Scouring agent 501 : 10~20g/l
Liquid Alkali(30%) : 9.5~20g/l
H2O2 (27%) : 12~24g/l
Alkali resistant scouring agent ( resistant to 150g/l alkali): 10~15g/l (as your demands)
Process :
Dip rolling scouring agent 501 preparation solution
1)cold batch (18-24 hours)
2)continuous process :scouring by dip rolling (95-100 ℃) → steaming 100 ± 3 ℃ x 60-90 minutes → hot water washing 3-5 water tanks - cold water washing
