Topic:   Spandex Technology - the Science of Stretch and Recovery
Date: Friday, February 20, 2004
Location:   Holiday Inn Northshore
5300 W. Touhy
Skokie, IL

Abstract:     Most spandex polymers may be generally classified as polyether-polyurethane-polyurea block copolymers. They are composed of crystalline hard segments dispersed in a matrix of amorphous soft segments. The dynamic interplay between the soft and hard segments determines the stretch and recovery properties of the polymer. The many compositional variables and their effect on polymer properties as well as the spinning process and its effect on fiber properties will be briefly reviewed. Macro- and microscopic properties of spandex fiber will also be discussed.

The JOB CLUB provides a continuing opportunity for unemployed members of the Section to meet one another, share their experiences and develop a network that may help in identifying employment opportunities. Bring plenty of resumes and business cards to distribute to your colleagues. A presentation of some of the primary resources that are useful for conducting a job search will be made.
