Reclaimed fibres breaking-down process

The degree of material break-down is descriptive of the spectrum of materials that results from the breaking-down process. It is defined as the proportions of fibres, threads, bits and remains of fabric in a specimen of 3 g or 10 g of the blend of reclaimed fibres, depending on the proportion of unopened pieces (by manual separation), in nnits of mass per cent. 

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... 

Breaking-down equipment should only be used to process waste which, in the end, can be made into reclaimed fibres. 

One effective way to lower the cost of making nonwovens of high mass per unit areas is seen in the elimination of some of the process steps and the combination of others for the production of reclaimed fibres and for web formation. This combination of processes makes use of a special breaking-down machine. It is designed to make a novel mat-like structure based on textile waste, eliminating some of the cost-intensive working steps. 

Yams are the conventional area where reclaimed fibres are used. However, to make the production of reclaimed fibres more economical, it is necessary to make use of up-to-date spinning processes. There is a solution described in which is a modification of the open-end spinning process. A breaking-down unit with an extra breaking-down roller breaks the fibrous particles still contained in the blend of reclaimed fibres. The particular way the extra breaking-down roller is arranged.
