Clay incorporated wet laid wood pulp based wound dressing for severe hemorrhage

Abstract

Nonwoven mats used for hemostat wound dressing was prepared by miniature wet laid nonwoven technique using wood pulp and kaolin. The wood pulp was dispersed along with kaolin in water medium and was wet laid by altering the process parameters. Optimum concentration of kaolin that can be loaded in the Web was found to be 2 gpl. The PBS swelling of the wood pulp/kaolin mat was 110% higher compared to the wood pulp control sample. The blood coagulation time for wood pulp/kaolin was 100 s whereas for the control sample was 250 s. The developed nonwoven mats have tremendous potential in trauma wound care.
