The claims defining the invention are as follows:
1. A method for the manufacture of a tufted product, in particular a tufted carpet
top layer where splittable fibres are used which split during tufting at/or in the
region of the insertion site.
2. The method as per Claim 1, where splittable fibres with a proportion of
between 10 and 100 % by weight are used.
3. The method as per Claim 1 or 2, where a mixture of splittable and non-
splittable fibres is used.
4. The method as per any one of Claims 1 to 3 where splittable fibres are selected
from at least two mutually incompatible polymer components.
5. The method as per Claim 4, where at least one polymer component has a lower
weight proportion than the other polymer component(s).
6. The method as per Claim 4 or 5, where at least one polymer component has a
weight proportion of equal to or lower than 20 % by weight, preferably of equal
to or lower than 10% by weight, more preferred of equal to or lower than 5 %
by weight and particularly preferred of equal to or higher than 3 % by weight
relative to the total weight of the fibres.
7. The method as per any one of Claims 4 to 6 where a polymer component with a
lower melting point is selected as the polymer component with a lower weight
proportion.
8. The method as per any one of Claims 4 to 7 where at least one polymer
component, preferably a polymer component with a lower weight proportion
than the other polymer component(s) is used as adhesive or binder component,
wherein the melting point of this polymer component is at least 10°C,
preferably at least 20°C below the melting point of the other polymer
component(s).
9, The method as per any one of Claims 2 to 8 where the non-splittable fibres are
selected from mono-, bi-, multipolymer component fibres and/or from mixtures
of such fibres.
10. The method as per any one of the preceding Claims where the fibres are
selected from thermoplastic polymers, in particular from polyesters, preferably
polyethylene terephthalate (PET), from polyolefins, preferably polyethylene
(PE) and/or polypropylene (PP), from polylactates and/or from polyamides
(PA), preferably polyamide 6.6 (PA6.6), and/or from the copolymers derived
there from.
11. The method as per any one of the preceding Claims where the splittable fibres
are selected from combinations of polyethylene terephthalate (PET) and
polypropylene (PP), of polyethylene terephthalate (PET) and polyamide (PA),
and/or of polypropylene (PP) and polyethylene (PE).
12. The method as per any one of the preceding Claims where the fibres selected
are those that have a titre in the range of between 5 and 20 dtex, preferably of
between 5 and 12 diex.
13. The method as per any one of the preceding Claims where the fibres selected
are those that have round and/or non-round cross sectional shapes.
14. The method as per any one of the preceding Claims where the fibres selected
are embodied as solid or hollow fibres,
15. The method as per any one of the preceding Claims where the fibres are
employed in the form of a fleece or a nonwoven fabric, in particular as a spun
fleece or a spun nonwoven fabric.
16. The method as per any one of the preceding Claims where the tufted product, in
particular the tufted carpet top layer, is subjected to a thermal treatment
following the tufting.
17. A tufted product, in particular a tufted carpet top layer manufactured in
accordance with a method as per any one of the preceding Claims.
18. A use of a tufted product, in particular a tufted carpet top layer, as per Claim 17
in automobile interiors and/or in residential, public or commercial areas, in
particular in offices, hotels, airports and/or hospitals.
19. A method for the manufacture of a tufted product, substantially as hereinbefore
described with reference to the accompanying figures.
20. A tufted product, substantially as hereinbefore described with reference to the
accompanying figures.
