Fiber and Biopolymer Research Institute to Hold Demonstration of Indigo Dyeing System

The prototype was made possible by a grant from the Walmart Foundation.

WHAT: Demonstration of a prototype system developed by the Texas Tech University Fiber and Biopolymer Institute.

WHEN: 8 a.m. Tuesday (Nov. 14)

WHERE: Fiber and Biopolymer Research Institute facility, 1001 East Loop 289

EVENT: Representatives from the Texas Tech University Fiber and Biopolymer Research Institute (FBRI), the City of Lubbock, the Lubbock Economic Development Alliance, the U.S. textile manufacturing industry and Walmart Foundation will be on hand for a demonstration of a breakthrough prototype system for applying indigo dye to cotton yarns using a foam medium.

The prototype was made possible by grants totaling $747,564 from the Walmart Foundation and an additional $41,700 from the VF Corporation. Making use of foam dyeing of cotton yarns feasible in denim manufacturing would save tremendous amounts of water and energy while eliminating the harmful chemicals used with current technology.

The demonstration will show the operation of the foam dyeing system that takes spun yarn packages directly into the system and puts out indigo-dyed yarns onto a beam.
