Description
The present invention relates to staple fibre yarn, comprise the fabric of staple fibre yarn and comprise the goods of this fabric.
WO 97/25464 discloses the staple fibre yarn that contains the right-aramid staple fiber that has 3 to 6dtex line density in each case.WO 97/25464 has instructed and can improve the goods of being made by this yarn by the line density that improves the staple fibre that forms yarn, the anti-cutting of gloves for example, wherein anti-cutting is meant the necessary power of these goods of cutting, and wherein incision length is measured as 25 millimeters.In addition, WO 97/25464 has instructed the staple fibre yarn with the staple line density that is higher than about 6dtex to produce the fabric that has fabulous anti-cutting really; But they are unacceptable aesthetic, and suitable snugness of fit is not provided yet.At last, WO 97/25464 has instructed to have less than the about staple fibre yarn of the staple line density of 3dtex and has produced the fabric that has good snugness of fit really; But along with the density of this staple fibre more and more descends below 3dtex, their anti-cutting constantly reduces.Therefore, WO 97/25464 has instructed the raising that can only realize anti-cutting under the situation of aesthetic acceptability of loss and snugness of fit, and can only obtain the raising of snugness of fit and the improvement of aesthetic acceptability under the situation of the anti-cutting of loss.
Therefore, the purpose of this invention is to provide to help making and have high anti-cutting and have the staple fibre yarn of the fabric of high snugness of fit simultaneously.
Realize purpose of the present invention by the staple fibre yarn that comprises short fibre mixture, this short fibre mixture contains staple fibre A and staple fibre B, if necessary, contain other staple fibre, its middle short fiber A and staple fibre B are made of the polymer that is selected from following group: aromatic polyamides, polyolefin, polybenzoxazole and polybenzothiozole, staple fibre A has line density T (A) and staple fibre B has line density T (B), and line density ratio T (B): T (A) is in the scope of 1.5:1 to 8.8:1.
Contain the fabric of staple fibre yarn of the present invention and comprise the goods of this fabric, for example gloves are compared with the fabric of being made in the same manner by a kind of staple fibre yarn that only contains the staple fibre with higher line density T (B), show identical at least, even higher anti-cutting.
This is surprising, because according to the instruction expection that provides among the WO 97/25464, the staple fibre that replaces having higher line density with the staple fibre with low line density can cause anti-cutting loss.Therefore, surprisingly, above-mentioned replacement does not cause that anti-cutting reduces.More surprisingly, because above-mentioned replacement can actually improve anti-cutting.
In addition, consider that the instruction that provides among the WO 97/25464 is (according to this instruction, use comprises the fabric that yarn that line density is lower than the staple fibre of about 3dtex makes and has low anti-cutting), surprisingly, staple fibre yarn height of the present invention comprises the anti-cutting embodiment (for example being classified as the embodiment of anti-cutting grade 3) that records according to DIN EN 388, and its staple line density T (A) and staple line density T (B) are starkly lower than 3dtex, so that the fabric of being made by this class yarn not only shows high anti-cutting, is feature with high snugness of fit and attractive outward appearance also.
Staple fibre yarn of the present invention contains staple fibre A and B, and its middle short fiber A and staple fibre B are made of the polymer that is selected from following group: aromatic polyamides, polyolefin, polybenzoxazole and polybenzothiozole.

Table 4 shows, by the cutting force of the gloves of making from the staple fibre yarn of embodiment 4b of the present invention recently from embodiment 4V
1Only the cutting force than the gloves of the mass area ratio low 3% of the gloves of embodiments of the invention 4b is high by 15% by the mass area ratio made of contrast staple fibre yarn.This is surprising, because aforementioned staple fibre yarn of the present invention comprises the staple fibre that 70 weight % have low line density, it should cause the cutting force of obvious reduction according to the instruction that provides among the WO 97/25464.In addition, table 4 shows, by the cutting force of the gloves of making from the staple fibre yarn of the present invention of embodiment 4a than make by the contrast staple fibre yarn from embodiment 4V
1The cutting force of gloves high by 12%, even in this staple fibre yarn of the present invention, existing 50 weight % staple fibres have low line density.Simultaneously, from the mass area ratio of the gloves of the present invention of embodiment 4a only recently from embodiment 4V
1The mass area ratio of contrast gloves high by 2%.
