  • It is effective even at lower concentrations
General Properties :
State Liquid
Density 1.2 g/cc
pH 8 ± 1
Ionicity Anionic
Solubility Soluble in water
Dosage 0.1 - 0.5% (owf)


Application :
Americos Opti-Bright XBL can be applied on the fabric at the final stage of processing or a stage earlier. It can be used in hydrogen peroxide/chlorine bleaching bath at elevated temperature of up to 150°C. The dosage may vary from 0.1% to 0.5% based on weight of material. The processing time can be adjusted between 10 to 30 minutes.
Storage & handling precautions :
  • Avoid storing in direct sunlight, Americos Opti-Bright XBL should be stored at ambient temperature
  • Do not allow freezing
  • If Americos Opti-Bright XBL is stored for long time, it is advisable to mix it well, before use

Americos White R Liquid (Fluorescent brightening agent) Americos White R Liquid is fluorescence brightening agent for polyester fibers. It gives brilliant whitening effect which has good fastness to sublimation, light and wet processing. It can be applied by high temperature exhaust or pad-thermo sol method and suitable for whitening effect on texturised polyester and polyester / cotton. It is available as nonionic fluid dispersion greenish yellow in colour. The dispersion is miscible with water and can be diluted to any desired concentration by adding water to it. It is recommended to adjust the ph of the bath between 4.5-5.5 as whitening effect may be reduce in extremely acidic or alkaline condition.

Method of application
Preparation of dispersion
The required amount of Americos White R Liquid is weighed out and stirred with 20 times of its weight of soft water at room temperature. The required volumes are made up adding more soft water.

High-temperature method
The bath is prepared with 0.1-0.35 % Americos White R Liquid 1.0 g/l suitable dispersing agent pH 4.5-5.5 with acetic acid Material to liquor ratio 1:10

The material is entered at about 50ºC and the temperature is slowly raised to 130ºC within 45-60 minutes. The treatment is continued at this temperature for about 30-45 minutes. The material is then washed in cold water and soaped at 60º-70ºC for 10-15 minutes in 2 g/l. Neutral detergent.

Pad-Thermosol method
Padding
The fabric is padded through a pad-liquor containing 1-5 g/l Americos White R Liquid at room temperature keeping 60-80% expression. The padded fabric is dried at approximately 120°-140ºC fixations. The fixation condition depends on fabric construction. Heavy or densely woven fabric requires higher fixation temperature or longer fixation time than lighter fabric with open weave.

However, following fixation condition may be taken as general recommendation:
For normal polyester & polyester / cotton: 180º-185ºC for 10-15 seconds.
For Texturised polyester : 170º-180ºC
The thermo fixed material may be given rinsing and light soaping treatment with 2g/l neutral detergent at 60º-70ºC. For 10-15 minutes.

Note: The recommendation is based on laboratory experiments and to be considered as guide lines only. For bulk production, it is necessary to carry out small scale trails to conform the local conditions.

The fastness properties were tested on polyester with 5 g/l Americos White R Liquid by pad- Thermosol method. The figures give the information on Change in whiteness
