3D Nonwovens

Developments for textured nonwovens

When you are looking for a possibility to increase the performance, the recognition and the uniqueness of your products, the use of a structured nonwoven is an excellent choice.  Structured products decrease the contact area to the skin, provide an additional volume of the product and influence the liquid management in a positive way because of a change in the porosity. Advantages, which are especially interesting in the hygiene market – for example as topsheet, backsheet or functional layer in diapers or femcare products.

Present structuring processes, like hydro entanglement, are slow and expensive. The new technology developed by REICOFIL in cooperation with ALBANY International (patent pending) structures your product fast and efficient. This process can basically be used on all existing REICOFIL lines, upgrades are possible.

The new process:
Using structured spin belts

In the REICOFIL process the filaments are collected and pre-bonded on a woven spin belt. The new technology provides a structure inside or on the spin belt, which leads to local changes of the air permeability in the belt. This influences the lay down and transferees the structure into the product. The laydown of the filaments is preferred in the area with the higher air permeability. This causes different fabric weights and thereby different thicknesses in the nonwoven.  

Function of the spin belt

The structured spin belt has mainly two functions: to create the desired pattern in the nonwoven and to ensure the process stability by the right construction of the spin belt (type of spin belt, way of weaving, air permeability of the ground belt vs. air permeability of the structured belt, etc.).


To reach these functions a variation in the structure of the spin belt (e.g. different web density, thicker warp thread which lead to a local increase of the spin belt surface) is possible. Another possibility is the adding of additional material on the spin belt. This method is very flexible and a wide range of different patterns can be applied on the spin belt. A third technology to create a structure in the nonwoven is the partial suction under the spin belt. This method can create for example lines in MD direction.  

Version 1

  • regulation of the air permeability of the spin belt by local blockages in the spin belt
  • generates e.g. line, dot or symbol pattern
  • the surface of the belt is still even
  • bonding e.g. with calender or hot air
  • this product shows a local variation in the fabric weight and this causes a different thickness and leads to a 3D nonwoven

Version 2

  • Create an elevation on top of the spin belt
  • generates e.g. line, dot or symbol pattern
  • Bonding preferably with hot air on the structured spin belt, e.g. at a “Full High Loft” product (crimped fibers PP/PE) or PP/PE in a core/sheath cross section
  • This product reaches a highly distinctive 3D surface structure
