Definitions
- the present invention relates to yarns, fibers or filaments, having improved abrasion resistance, and in particular usable for the production of felts for paper machines. It relates more particularly to yarns, fibers or filaments based on polyamide or polyester.
- the properties which must be present in spun articles are different according to their use. Among these, there may be mentioned for example the mechanical resistance, the transparency, the gloss, the whiteness, the dyeability, the shrinkage, the water retention capacity, the fire resistance, the stability and the heat longevity ...
- a property which may be required, in particular for applications in industrial fields or in so-called technical wire fields, is abrasion resistance.
- felts which are composite structures comprising a stack of layers of woven fabrics (obtained from continuous monofilaments) and layers of nonwovens (obtained from cut fibers), the layers being assembled in general by needling.
- the increase in abrasion resistance generally makes it possible to increase the life of articles made from yarns, fibers or filaments.
- felts for paper machines which are made from synthetic fibers
- this property has become critical for many reasons: replacement of chemical bleaching agents by solid particles, for example calcium carbonate, increase in the speed of production or operating temperatures of paper machines that stress felts more critically.
- This is also the case, for example, for carpets and rugs, cords and belts, nets, fabrics used in the field of screen printing or filtration.
- a possible alternative, described in patents US 5,234,644 and US 5,783,501, consists in producing yarns or fibers of conventional molecular weights and then increasing, a posteriori (on the fiber in the case of US5234644 or on the felt in the case of US5783501), the viscosity of the polymers.
- This solution has limitations, however. Thus this adds an additional step in the process and requires the use of chemical solutions containing catalysts.
- Another known solution consists in spinning polymers of high molecular mass but which one seeks to reduce the melted viscosity. This can be obtained through the use of polymers comprising star macromolecular chains.
- the polymers comprising such star macromolecular chains are for example described in the documents FR 2,743,077, FR 2,779,730, US 5,959,069, EP 0.632,703, EP 0.682,057 and EP 0.832,149. These compounds are known to have improved fluidity compared to linear polyamides of the same molecular weight. However, the yarns, fibers or filaments obtained from these polymers do not have good abrasion resistance properties.
- Another solution for improving the abrasion resistance of articles made from fibers consists in using articles having a three-dimensional crimp, as described in patent CA 2076726.
