KDK curly yarn

Knit De-knit (KDK) is a form of texturizing wherein a crimped yarn is made by knitting the yarn into a fabric, and then heat-setting the fabric.  
The yarn is then unraveled from the fabric and used in this permanently crinkled form.

-the KDK yarn is more filled and completed,  better resilience ability,   higher retraction which means turf with better density
