FLUORESCENT BRIGHTNER FOR POLYSTER FIBERS AND THEIR BLENDS
Nature |
Strylbenzene derivative, nonionic. |
|
Storage |
When stored correctly, in sealed containers, Ultrashine RFR Liquid has a shelf life of up to 24 months. The dispersion should always be well stirred before removal from the containers. |
Properties |
Yellowish dispersion. The White effects produced are more or less reddish/bluish in tone, depending on the amount applied. Miscible with cold water in all proportions. Solutions of the product, and fabric that been padded and dried but not fixed, must be protected from light. Stable in reductive bleaching liquors and in those, which contain hydrogen peroxide or sodium hypochlorite. Because of its high yield, Ultrashine RFR Liquid is extremely economical. Even small amounts produce brilliant white effects of a high standard. In the exhaust process, at the boil, it is necessary to use a carrier. The product is less suitable for brightening CA, CT and PA. |

Guideline recipes |
|
HT Process |
0.1 – 0.5% Ultrashine RFR Liquid Liquor ratio, 5:1 to 20:1 |
Carrier Process |
0.1-0.5% Ultrashine RFR Liquid Liquor ratio, 10:1 to 20:1 |
Thermosol process, Two-stage drying and fixation |
0.5-5 g/1 Ultrashine RFR Liquid The fixation conditions depend on the fabric construction. Tightly woven and relatively heavy qualities require longer fixation times or higher fixation temperatures than lightweight, open materials. The padded and dried fabric should be protected from prolonged exposure to light, because the unfixed fluorescent brightener is sensitive to light. |
Single-stage Drying |
In this procedure, the equipment used has a considerable influence on the fixation time and temperature; for this reason, conditions based on experience are more reliable than general recommendations. In cases of doubt, it is advisable to carry out preliminary trials. The amount of Ultrashine RFR Liquid used is the same as in the two-stage drying and fixation process. |
Curing Process |
Ultrashine RFR Liquid can also be fixed under the conditions provided by resin finishing and other finishing treatments. |
Fixation Process for the |
The fluorescent brightening of print grounds is frequently carried out in conjunction with the thermosol process. |
Knit goods produced from texturized PES are also brightened by the HT process (eg. Data concerning the thermosol and HT processes).Under the fixation conditions Employed in textile printing. White effects produced with Ultrashine RFR Liquid Behave as follows:
