Applications of Kuralon K-II^®
The most successful applications of KURALON K-II water soluble fibers concern:

• The spinning of fine wool yarns (from Nm 1/80 to Nm1/150) using coarser wool fibers than those normally needed to get fine count yarns;
• The weaving of “Natural Stretching” fabrics without using elastomeric filament yarns;
• The weaving of single end yarns of noble fibers otherwise difficult to be processed;
• The knitting of warm, light and soft fabrics for fashion using less wool and noble fibers thus saving expensive raw materials;
• The knitting of “devoré” fabrics; 
• The weaving of natural and artificial fabrics to achieve better wearability and breathability.

Kuralon K-II® technical assistence 
is available on demand based on the customer products and production process.
