SALPHOR-HT White R Liquid (Fluorescent brightening agent)

SALPHOR-HT 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 color. 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 applicationPreparation of dispersionthe required amount of SALPHOR-HT -White R Liquid is weighed out and stirred with 20 times of it’s weight of soft water at room temperature. The required volumes are made up adding more soft water.

High-temperature methodThe bath is prepared with 0.1-0.35 % SALPHOR-HT  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 methodPaddingThe fabric is padded through a pad-liquor containing 1-5 g/l SALPHOR-HT -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.
