Abstract:
This research aims to determine an optimal factor setting for non-woven heat coating process in order to control the weight per square meter after coating within
a standard range (190 gsm +/- 5%). Base on the study, there are four main factors influencing the weight, which are roller gap, roller speed, pressure, and ratio between latex and water. A response surface experiment is conducted to determine an optimal setting of the mentioned factors. The result shows that using the roller gap of 0.69 mm, roller speed of 15%, tension of 30%, and ratio between latex and water of 20 : 60, the weight per square meter after coating is 190.21 gsm on average, which is in the standard range.
