Researchers at the University of California, Davis have developed a novel and high throughput production process of making nano/submicro-sized fibers.
Researchers at the University of California, Davis have developed an environmentally friendly manufacturing method for nano, micro and sub-micro fiber. The process uses a hybrid cellulose acetate butyrate (CAB) system, with CAB as a matrix material. By extruding in-situ micro or submicrofibrillar CAB and polymers (polyolefin, polyesters, and proteins) into regular size fibers, CAB serves as a sacrificial matrix and other polymers as micro/nano-fibrills in the matrix in coarse fiber form. After removal of CAB with acetone extraction, micro, as well as, submicro fibers can be produced.
