The FiberVisionsâ HY-Soft is presently produced at the FiberVisions a/s plant in Denmark. HY-Soft is the trademark of FiberVisions.
Features & Benefits
- Materials Features
- Major Features Are
- Unique softness
- A fiber with good nonwoven processing:
- Broad bonding window
- Low bonding temperature
- Normal carding speed
- The nonwovens strength and elongation properties can be compared with the properties of other FiberVisionsâ fiber types
- The fiber is available in a hydrohilic as well as a hydrophobic version and various botanical finishes
With regard to other fiber properties the FiberVisionsâ HY-Soft fiber behaves in the same way as the other FiberVisionsâ longspinning fibers:
- A controlled surface characteristic ensures optimal bonding conditions
- The uniformity of the fibers ensures stable processing conditions minimizing down-time and downgraded materials
- The FiberVisions concept of adapting the fiber to suit the individual carding line maximize
- In several softness tests (internal FV method) nonwovens made of FiberVisionsâ HY-Soft score significantly higher in "softness" than other nonwovens made of other PPfiber types.

Technical Details & Test Data
- Test Data
Results from FiberVisions a/s pilot carding & calendering line FiberVisions has obtained the following nonwovens data from tests on the carding & calendering line at 100 m/min carding speed (Typical data for a 20 g/m² product):
From the below graph it can be seen that nonwovens made of HY-Soft achieved their highest tenacities at approx. 8-10 °C lower temperatures than normal PP-fibers:
