Spinning
Kanecaron can be basically spun in the same manner as other synthetic fibers.
However, for better quality, the following technical points are advised:
- Atmospheric conditions
Temperature range: 20-25 degrees centigrade
Humidity range: 50-60% relative humidity (R.H.)
- Opening / Carding
As with other synthetic fibers, excessive action is not needed here.
- Drawing - Winding
Since Kanecaron elongation is high (the same as regular acrylic fiber, approximately 30%), too much tension may affect yarn quality. It is recommended that appropriate conditions and spinning systems be selected, considering the properties that Kanecaron has as outline above.
- Equipments
Use of plated wire and a plated ring are suitable to avoid corrosion.

Dyeing
Kanecaron can be dyed with cationic dyestuffs in a manner similar to that used for regular acrylic yarn. However, for better quality, the following precautions are advised:
- Kanecaron tends to absorb a dyestuff rapidly, starting at around 85 degrees centigrade. It is recommended to raise the temperature gradually after reaching 85 degrees centigrade.
- The temperature should not exceed a maximum of 98 degrees at any time. Kanecaron starts excessively shrinking and begins to stiffen at 100 degrees centigrade. The Protex series, which consists of high heat resistance types, can be dyed at 103 degrees centigrade.
- When using a retarder, reduce the amount normally used for regular acrylic fiber / yarn / fabric.
- The following are recommendable recipes for various shades:

*auxiliaries
In case of light shades, use either a PAN or AN type retardar.
For dark shades, use a carrier for dyeing, followed by reduction cleaning.
If using ED dyestuffs, neither retardar nor carrier are needed.
