Reclaimed fibres quality parameters

As can be seen in Table 9.3, both the aerodynamic and mechanical processes of web formation raise different questions with regard to the quality of reclaimed fibres. When producing the fibres, quality parameters can be set to some degree. 

It is most important to have reclaimed fibres available which are of the right quality with regard to the purpose and which are cheaper than primary fibres. Quality is expected, throughout the whole production period, to constantly remain within the parameters defined. Such parameters can, and should, be documented. 

After-treatment should focus on the further enhancement of the quality parameters reached in the breaking-down process, so that the reclaimed fibres become more competitive. The steps to be taken include... 

At the point of the producer of reclaimed fibres handing the materials over to the user, it is helpful to have a syslan of quality assessment available that allows the documentation of the technological parameters of the material. It will oeate the base on which contracts can be negotiated and questions of warranty clarified between the producer and the user. Such a system should help to define the parameters below within a short time and at low-cost ... 

Geotextiles may be looked upon as an ideal field for the application of reclaimed fibres. To make them, it is important to use well-selected textile waste and to exactly tune the process parameters when breaking it up. In this way the quality requirements below can be met ...
