It is a splittable short cut staple fiber, featuring Kuraray’s original cross-section shape.
The fiber splits into fine and flat 11 fibers by just dividing.
WRAMP displays various performances depending on how it is used. It can make papers add soft touch, or increase density by contracting the paper mesh.
Specialty papers made from this fiber are used in cosmetics, such as base material for face mask, featuring its soft touch. Its potential use is further expanding and it is now under consideration to use this fiber for filters, featuring its capability of increasing paper density.
- Soft touch
- By processing the paper made of WRAMP by water-jet (*1), flat fibers softly intertwine with each other, creating a unique sheet with peach-soft touch.
- High density
- In the production process of paper, flat and fine WRAMP fibers are piled up each other. This makes it possible to create tightly-spaced high density papers. The density of paper can be controlled by mixing WRAMP and ordinary circular cross-sectional fibers.
※1 A processing method of spraying high pressure water streams through numerous small nozzle holes to enable sheet fibers to intertwine with each other. Expressions of sheets can be changed in a variety of ways by arranging the water stream.
