As the parameters of the dry fabric were determined, the kenaf yarns were self-woven into plain 1/1 (Fig. 1) using “Floor Loom”.
The Vf in form of composites was calculated according to the equation (1) [7]: Vf = n.m ÷ ρ.h (1) Where n is the fabric ply number in the composite, m is the areal density of the fabric, ρ is the density of the fiber (1.2g/cm3 [8]) and h is the measured thickness of the composite.

Three different panels were produce with different thickness (measured using a caliper); 276tex thickness panel 1.39mm, 413.4tex thickness panel 1.62mm and 759tex thickness panel 2.50mm.

Other characteristics are listed in Table.1.
When the pulse width is between 1ms and 1.5ms, the motor is in a forward mode; when the pulse width is between 1.5ms and 2ms, the motor is in a reverse mode; and when the pulse width is 1.5ms, the motor stops.

In Fig.1, Ii (i = 1,2, ..., n) is the neural network input layer neuron.
Input layer neuron Ii (i = 1,2, ..., n) is correspondence with the customer feature subset.
Fig.1 Neural Network Model The output layer only has an output neuron.
When the feature set of the same demand class is set for training, the ideal output is “1”.
