into automatic control of dyeing machinery.

1 27 Mercerization and Dyeing of
Kenaf/Cotton Blend Fabrics
By Gita N. Ramaswamy and Jinhua Wang, Kansas State University;
and Bambang Soeharto, Mississippi State University
Research supports a hypothesis that kenaf/cotton fabrics can be
finished conventionally like 100% cotton fabrics.

32 Levelness of Dyeing and Unwinding Performance
of 100% Polyester Two-Ply Yarn Packages
By Yiqi Yang and David C. Allegood, Institute of Textile Technology
Two-ply polyester packages were dyed with liquor flow rate and
package construction variations to determine the effects on
levelness and unwinding performance.
