Thermo-mechanical properties and b) stress-strain curves of PLA and modified PLA

Hamid Ebrahimi recently graduated with a Ph.D. in Fiber and Polymer Science from North Carolina State University where he studied polylactic acid (PLA) structure-process-property relationships with other biodegradable polymers. His research was conducted through the Nonwovens Institute (NWI). The NWI serves as a bridge between industry and academia, where students can get the best of …

The European Commission’s Single-Use Plastics Directive (SUPD) has been hotly debated since its initial publication in July 2019. While the aim of the legislation is a noble one – minimizing plastic waste in the environment – getting a firm grasp on what is, and what is not, a plastic has proven to be more challenging …

Incorporation of fiber grade CaCO3 into PP nonwovens

Calcium carbonate, which is ubiquitous in nature, can be found everywhere in daily life. It is used widely as a coating agent for paper or cardboards and for paints; as an additive in food pharma and cosmetics; as a soil fertilizer in agriculture; for water remineralization; for flue gas desulfurization; and many other applications. In …

Polarized light microscopy of liquid crystal

The Soft Functional Materials Lab @ VCU is motivated to apply fundamental science to solving challenging and practical problems. The lab focuses on the processing and characterization of soft functional materials with applications in biomedical and environmental engineering. Lab members work at the interface of polymer science, nanotechnology and biotechnology, to design, process, and apply …

Evolon® New Generation is a bicomponent technology made from super-microfilaments

A biocomponent fiber, or bico, is a fiber that combines two separate polymers into a single filament. The term conjugate fiber is also used as a synonym.    The process of making a bicomponent fiber is relatively straightforward. There are a number of patents that describe this practice. Commonly, the fiber is constructed of two …
