Product information
Product name: OPTICALBRIGHTENER ER Liquid(PS-1. ER330)

Color Index No: C.I.199

Synonyms: FBA 199; OBA 199,Fluorescent Brightener PS-1(ER330); Optical Brightener Agent PS-1(ER330)

Molecular Structure:
Molecular Formula: C24H16N2

Molecular Weight: 332.3972

CAS No: 13001-39-3

C.I. No.: C.I.199

Appearance: yellowish pulpy liquid

E-value: 330

Features:
Thisproduct is mainly used for whitening and brightening of blending fabrics suchas polyester and polyester cotton, polyester silk, polyester yarn, polyesterramie, polyester wool as well as whitening of chemical fiber and plastic. Thisproduct applies to pad dyeing and HTHP dip dyeing, especially low temperatureadsorption and high temperature setting process.
Applications
1. Pad-dyeing hot melt method:

Use quantity: 1.5-3g/L

Process flow: two dip dyeing and two paddyeing (mangle expression 70) pre-drying (100) curing and setting (180 190, 40-30s).

2. HTHP dip dyeing method:

Use quantity: 0.2 0.5% (o.w.f)

Dyeing temperature: 120 130

Dyeing time: 30 - 60 minutes

PH value: 4.5 - 5.5 (adjusted withacetic acid)

Low temperature adsorption and hightemperature color development dyeing method:

Use quantity: 0.5 1.0% (o.w.f)

Dyeing temperature: 50 60

Dyeing time: 30 minutes

PH value: 4.5 - 5.5 (adjusted withacetic acid)

Process flow: add BC-100 whitening agentand additive (anhydrous sodium sulphate 1-2% relative weight of dyed cloth,acetone is adjusted in PH) and fabric to dye bath at room temperature temperature rises to 50, deying for 30min washing dehydration and pre-drying (100) setting and baking (180-190, 40-30s).

Package & Storage:
25kg/50kg plastic drums. It can be packedin other forms according to user's requirements.

Shelf life: not more than 12 months inthe room temperature.

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.
