Cut resistant composite yarn
The invention relates to a cut resistant composite yarn comprising: a) at least one yarn containing filaments and/or staple fibers, said filaments and/or staple fibers containing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most (25) microns; and b) at least one continuous elastic filament. The invention further relates to a fabric and articles comprising the yarn, in particular a glove.
1. A cut resistant composite yarn comprising:
(a) at least one continuous elastic filament; and
(b) at least one first yarn wrapped around the at least one continuous elastic filament, wherein
the at least one first yarn comprises polymeric filaments and/or staple polymeric fibers and a hard component, wherein
the hard component of the at least one first yarn consists of a plurality of hard fibers selected from the group consisting of glass fibers, mineral fibers and metal fibers having an average diameter of at most 25 microns; and wherein
the cut resistant composite yarn has a titer of between 100 and 1000 dtex.
2. The yarn of claim 1 further comprising at least one yarn containing filaments and/or staple fibers of polyester and/or nylon.
3. The yarn of claim 1 further comprising at least one yarn containing melt spun filaments and/or staple fibers of polyethylene.
4. The yarn of claim 1 further comprising at least one yarn containing gel spun filaments and/or staple fibers of ultrahigh molecular weight polyethylene.
5. The yarn of claim 1 wherein the first yarn has a titer of between 100 and 400 dtex.
6. The yarn of claim 1 wherein the elastic filament has in the relaxed state a linear density between 8 and 220 dtex.
7. The yarn of claim 1 wherein the elastic filament is manufactured from a long chain synthetic polymer comprising segmented polyurethane.
8. The yarn of claim 1 having a titer of between 200 and 500 dtex.
9. A lightweight, cut resistant fabric comprising the yarn of claim 1 .
10. The fabric of claim 9 , said fabric having a cut resistance as measured by ASTM F 1790-97 above 500 g and an areal density of at most 400 g/m 2 .
11. The fabric of claim 9 wherein said fabric is manufactured on an at least 15 gauge knitting machine.
12. The fabric of claim 11 where the knitting machine was at least 18 gauge.
13. A glove comprising the fabric of claim 9 .
14. The glove of claim 13 , the surface of which being at least partially coated with a polyurethane based elastomer.
15. The yarn of claim 1 further comprising at least one yarn comprising filaments and/or staple fibers formed of a thermoplastic material in the absence of hard fibers.
