FINISH 181-PSY

This is material based on compounds of organophosphorus ester, it is used for durable flame retardant treatment for polyester fabrics. Fabrics after treatment can reach flame retardant B1 grade according to Standard GB17591-2006.

Characteristics and advantage:
◎ Impart 100% Polyester fabrics with excellent fire retardancy.
◎ It is a durable flame retardant, many times washing resistant for finished fabric;
◎ There is no influence on strength, hand feeling, no color shade changes and bleeding.

Basic property:
Appearance : light yellowing transparent liquid
pH value: : 2.5-3.5(1% aqueous solution)
Solubility: : diluted with water by any ratio
Solid Content: : 92% +/- 1 %

Application field:
Car internal decoration, finishing fabrics for train, ship, plane, tent etc.

Recommended dosage:
Finish 181-PSY: 100-200g/l
10-20% NaOH: Adjust PH value to 5.0
One dip one padding, (liquid rate 65-70%) → drying（100-120°C/ 1-2min）→Cure(180-190°C/ 1-2min）→ 40°C washing → cold water washing → drying

Action:
● Above formula and process can be adjusted according to practical situations;
● Baking temperature and time decide the fastness of flame retardant agent, low temperature will influence the durability and effect of FR;
● There would be some little influence to some colors, pre-testing is needed before
producing;
● The washing process can be omitted according to practical situations.
