Uses

The use of FiberVisions® HY-Care B in nonwoven fabrics has a proven product performance regarding:

• Good nonwoven tenacities and liquid repellency characteristics
• Good cardability and a broad bonding window
• High carding speeds possible after optimization of the fiber to suit the machinery configuration
• The nonwoven fabrics have a superior softness and texture when compared to spunbonded materials The use of carded, thermal-bonded coverstock fabrics in leg cuffs and textile backsheet application ensures materials with high fabric uniformity without weak spots
• Fibers and nonwoven fabrics which can be laminated to film due to the broad bonding window

The consistent high quality and uniformity of the fibers ensure a good web uniformity, which enhances the hydrophobic properties of the nonwovens. Carded, thermal-bonded nonwoven fabrics do not have weak spots in the fabric which reduce the hydrophobicity, in contrast to spunbonded fabrics.

Technical Details & Test Data

Test Data

Rising Water Column

The following nonwoven repellency values (Internal FiberVisions test method) are obtained from coverstock fabrics from HY-Care B fibers in 2.2 dtex: Normally, a 1.7 dtex fiber would result in a higher rising water column test result.

Availability

FiberVisions® HY-Care B fibers are available in 1.7 and 2.2 dtex. The fine fibers will increase the hydrophobicity of the nonwoven fabrics due to an decrease in pore size and the higher uniformity of the fabric.
