example 1
[0181] Experiments were performed with varying amounts of water delivered to each of the 10 fiberizing units. Ten set points or examples according to Table 1 are indicated below. The liquid enters the forming hood either as binder dispersion, as diluent for binder dispersion, or as coolant water, the values of each varying as shown in Table 1 or held constant. Setpoints 1 and 9 are designed to control with reduced or distributed diluent and coolant water at low average values representative of the current state of the art. Other set points hold the various water sources constant or are flat at higher averages, while other set points vary or spread from one unit to the next. Flow is given in liters per minute LPM.

[0193] Significant relationships have been found between the variables represented in Table 2. For example, it has been discovered that Vertical Weight Distribution (VWD), also understood as a product property of Vertical Density Distribution, a measure of recovery and a measure of stiffness are utilized when the tow exits the forming zone and returns to its uncompressed state, the "charge height" When the thickness of the fiber bundle is increased, it is significantly improved.
[0194] R-value insulating batts with R12 and R20 are produced in standard commercial operations. Quality control data was examined from these manufacturing runs to obtain EOL recovery and stiffness / sag values at varying run times. Product data is mined to obtain charge levels, and these charge levels are matched with corresponding product properties for each selected run time. It was found that for R12 and R20 felt recovery and stiffness / sag exhibited a correlation with charge height. Figure 6B...

[0197] Experiments were also performed to determine the effect of the relative amounts of binder flow and coolant water flow. For binder flow set points of 4, 5 and 6 LPM, binder concentration was adjusted for equal delivery of binder chemistry (same solids / same LOI content). The flow of coolant water is varied and the charge level is monitored. For each adhesive flow value (4, 5 or 6 LPM), the minimum and maximum charge heights were approximately equal, roughly a minimum of 250mm and a maximum of 450mm. But at each different binder flow (4, 5 or 6 LPM), different values of coolant flow were used to obtain the same charge height value. As expected, the value of the coolant flow had to be increased to obtain a comparable charge height when the binder flow was flowing downward. Thus, the charge level is related to the total water volume provided to the forming hood.
