I also corresponded with Cameron Holt of the Melbourne College of Textiles about his work involving suri fiber. Some of the information found here was from notes taken at an alpaca breeders clinic held in 1996 at Oregon State University at which Dr. Julio Sumar was the featured speaker. The answers to the questions posed were consistent from one expert to the next, unless otherwise noted. Suri fiber is utilized in the worsted spinning process. Little if any suri is spun using the woolen system.
Suri fleece is more similar to mohair than merino.
Suri cloth is always brushed in the finishing process to bring out its natural luster. The fabric makes up into beautiful women's and men's overcoats, which are its primary end use. Suri is scarce. When the fashion trade demands suri in any volume, the orders are hard to fill and the price increases quickly. Recently the price of suri has been very high.
