5. Adhesive Characteristics
We conducted a preliminary test using the purchased spray adhesive.
The samples were sprayed and agitated, then left to set for several days.
Bond Strength refers to the relative combined tensile strength of the interlaced fibers and the adhesive holding the fibers together.
"Fluffiness" refers to the relative density of the product, after the adhesive was applied, the fluff was agitated in an attempt to glue the fibers together more evenly.
Roughness refers to how the products feel on the surface, as stated above the adhesive was likely applied to heavily and unevenly, this resulted in clumps and mats of adhesive and fluff surrounded by relatively untouched sections of fluff.

6. Burning Characteristics
Flame Spread refers to the speed that an initial flame engulfed the rest of the product. The denim spread the flame significantly faster than the synthetic mix.
Rate of Smoke Development refers to the amount of smoke that was produced while the product was actively burning as well as after it was only smoldering.
Flame Strength refers to the material’s tendency to keep burning.
While the specimens with adhesive on them did show a lower rate of flame spread, it is more likely that the compressed nature of the specimens had more of an effect than the actual adhesive. The adhesive did make the specimens extremely hard to extinguish.

7. Prototype 1 Process: “Fluff” shredded denim
Treat with borate solution (flame retardant)
Air dry overnight, re-fluff
Thin layer into form
Layer of tacky adhesive
Another layer of denim
DBC

8. Prototype 1 Results What we Learned:
“Fluffing” is a required step in the process
Team looking into how to do this more quickly and consistently
It is feasible and our prototype form works great LJ

9. Some Interesting Data... Prototype Weight: 4.6 oz
Resulting Density: ~ 1 lb/ft^3 (compared to Bonded Logic 1.4 lb/ft^3)
This difference could very well be due to measurement/calculation error
Have Enough Material to Make ~ 150, 12” x 12” x 3.5” prototypes
Note: Our shredder contact can get us a 600 lb bale if we get to the point where we want to make full-size batts for testing LJ

10. Reducing Sag
Initial idea of adding synthetic fibers to product in order to reduce sag
Adding synthetics will significantly increase smoke development
Hydrophobic Spray/Coating
Proposed Option - Testing Early Next Semester
Wire Inserts
Proposed Option
Spring Inserts
