For Print-Bonding Non-Wovens |
| 配方组成： |
A typical composition suitable for print-bonding nonwoven fabrics
where a very high level of flame retardancy is essential, is as follows
Ammonium hydroxide/0.9
Ammonium hydroxide/0.3
"Cellosize" QP 4400 (4% solution)/17.3
Ammonium sulfamate (60% solution)/37.0
"Rhoplex" TR-520/44.5 |
| 配制方法： |
Additions should be made in the indicated order. The ammonium sulfamate solution in particular should be added carefully in small increments. At this high level of salt, "Cellosize" QP-4400 has been found to be the preferred thickener. Final pH of the composition is 8.5 and the initial viscosity is 3310 cps.
