Title
Device for backward needling of non-wovens. The problem the inventor(s)
wanted to solve Elaboration of a device for backward needling of
non-wovens. Description.
The essence of the invention is a device with two
needling beams situated opposite to one another. The beam needling pull out
fibers from the neighboring pile layers and draw them in opposite directions.
Such method of fiber movement causes their mutual entanglement, much stronger
than in non-wovens needling traditionally with an influence on their tensile
strength. Presentation.
POSTER Description of the invention and the schematic
diagram.. Fields of application
Double-faced needle non-wovens can be applied as
filling of duvets, sleeping, bags, ski jackets and as filtering materials
used in filtration of gases. Advantages
The product manufactured on this device has
many advantages, namely: high fluffiness, very good heat-insulating
properties and strong bonding of fibers within the inside layer. Documentation available:
