Greeson was recognized for his contribution toward the major revision of AATCC Test Method 97 (Extractable Content of Textiles) for the 2014 AATCC Technical Manual. Greeson attended North Carolina State University (NCSU) and graduated with a Bachelor of Science in textile chemistry. His current position at Cotton Incorporated is Manager, Textile Chemistry Research, in the Textile Chemistry Research department. His primary responsibilities include research and development in the field of fabric finishing, including areas such as wrinkle resistance, moisture management, repellency, flame retardancy, and abrasion resistance.

SERICIN AND FIBROIN SPECIFIC STAIN USED TO CHARACTERIZE SILK FILAMENTS

Filament silk or bombyx mori silk is extruded from two seperate glands in the region of the spinerette on the silkworm’s head as it spins its cocoon. These two filaments are composed of beta pleated sheets of fibroin protein which are joined together by a sericin outer sheath which is simultaneously extruded from two other glands in the region of the silkworm’s spinerette.

The sericin outer sheath and fibroin inner region can be seen in the following low and high magnification scanning electron micrographs:

To further differentiate the sericin/fibroin interface Vartest has developed a stain which colors the sericin outer sheath purple and the fibroin filaments pink as seen in the following light micrograph:

The sericin surrounding the bave has been stained purple, the two fibroin brins pink.

 

The two fibroin filaments in combination with the sericin outer sheath is known as a bave, while the individual fibroin filaments are known as brins.

Vartest combines multiple testing and analytical techniques to fully characterize fibers both as manufatured and in end use.
