The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer and a discontinuous fibrous material in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. The elastomeric (meth)acrylate random copolymer may be contained within a thermoplastic pouch, and the hot melt mixture may include a relatively high level of tackifying resin. The elastomeric (meth)acrylate random copolymer may contain branching agents and photosensitive crosslinking agents. The hot melt processable pressure sensitive adhesives can be used to prepare transfer tapes.

Method for producing a fibroin powder from silk products or filaments without sericin and dyes having the following phases: a) introduction of products or filaments into a very tightly-woven sealed bag with high filtering capacity to allow the treatment liquid but not the silk fibrils to exit; b) introduction of the bag into a tank with fresh and hot water with a mixer, in which soda is added to the water for a time of some hours; c) a rinsing phase of which the last is made with acetic acid in such a way as to make the fiber acceptable to the cutis as originally; d) phase of centrifugation and drying tumbler; e) tumbling phase, first opening the bags to throw away the material dried in the tumblers by pulverizing the fiber with a homogenous fragmentation in such a way as to keep the fibrils whole.

The disclosed invention is a method for using collagen extracted from animal bones, hides, and flesh waste as a protein-based glue (Bone Glue) to create asphalt with a modified asphalt binder. The method comprises of mixing Bone Glue with water, adding it to an asphalt binder, evaporating the water, adding the modified binder to aggregate and mixing at an elevated temperature. The modified asphalt binder consists of a predetermined amount of Bone Glue and asphalt binder.
