COMPOSITE DRESSINGS, MANUFACTURING METHODS AND APPLICATIONS THEREOF
20210252182 · 2021-08-19 ·

The present disclosure provides a composite dressing comprising a combination of porous matrix and fabric substrate wherein at least one of said porous matrix and fabric substrate is composed biomaterial(s) and wherein the fabric substrate is at least partially embedded in the porous matrix. Further, the disclosure provides a method for preparation of said composite dressing, wherein said method enables production of the composite dressing having cohesive bonding between porous matrix and fabric support without use of any adhesive, stitching or chemical crosslinking agent between the two layers. The composite dressing exhibits high peel strength in both dry and wet conditions and has applications such as hemostatic dressings for deep cavity wounds, puncture wounds, post-partum hemorrhage and internal hemostatic agents.

EARTH PLANT COMPOSTABLE BIODEGRADABLE SUBSTRATE AND METHOD OF PRODUCING THE SAME
20210238390 · 2021-08-05 ·

An earth plant-based compostable biodegradable composition for the formation of a bioplastic and method of producing said resin, the composition comprising: about 17.5 to 45% ethanol-based green polyethylene by weight, about 20 to 25% calcium carbonate by weight, about 2 to 12% hemp hurd or soy protein by weight, about 32 to 45% starch by weight, and about 0.5 to 1% biodegradation additive by weight to enable biodegradation and composting of the bioplastic; wherein the composition is produced by first mill grinding the ethanol-based green polyethylene, calcium carbonate, hemp hurd or soy protein, starch and the biodegradation additive into fine powders, then mechanically mixing the fine powders one by one into a final mixture for about 5-25 minutes at a time, dry and without heat, and then heating the final mixture to about 220 to 430 degrees Fahrenheit.
