Definitions

  • the present invention relates to a lace fabric, typically a raschel fabric, which includes a number of wales of warp barns knitted in the form of loops and a method of manufacturing such lace fabric. More specifically, the invention relates to a lace fabric having wale-wise elasticity and a method of manufacturing the same.
  • a lace fabric is formed by knitting of yarns.
  • a lace fabric of a type which is provided with positively increased wale-wise elasticity and expansibility by introduction of an elastic yarn such as a single rubber yarn or filament into some or all of wales forming the lace fabric, in addition to the slight elasticity inherent in lace fabrics in general per se.
  • Fig. 3 shows a raschel warp-knitting machine which is one example of lace knitting machines for use in knitting such lace fabric as above.
  • Fig. 4 shows an exemplary lace fabric knitted by this machine and taken up about a fabric take-up roll of the machine.
  • This raschel warp-knitting machine 20 includes a knitting head 24 for knitting the lace fabric 10, a take-up roll 25 for taking up the fabric 10 having been knitted by the knitting head 24, a ground-yarn beam 21 for threading ground yarns 11 such as a warp yarn 2, a weft yarn 5 and the like to the knitting head 24, an elastic-yarn beam 22 for threading an elastic yarn 4 to the knitting head 24 to be interlaced with the warp yarn 2, a pattern yarn beam 23 for threading a pattern-forming yarn 6a to the knitting head 24 to be introduced between the ground yarns 11 for forming an ornamental pattern in the knitted fabric 10 and other components.
  • the knitting head 24 though not shown, includes a plurality of guide gars for guiding the ground yarns 11, elastic yarns 4, pattern-forming yarns 6a and the like, a plurality of knitting needles for chain-stitching the warp yarns 2, and a needle bar for vertically guiding the plurality of knitting needles.
  • the lace fabric 10 is formed by this knitting head 24 and then taken up about the take-up roll 25.
  • One vertical reciprocating movement of the knitting bars forms one course 7 of loops 3 of wales 1. Details of these operations will not be provided herein.
  • Fig. 4 shows an example of the lace fabric 10 taken up about the take-up roll 25.
  • One simultaneous reciprocating movement of the plural needles chain-stitches loops 3 of a plurality of wales 1 at a time, with the weft yarn 5 being inserted between a loop portion 3a and a sinker portion 3b of some of the loops 3 so as to interlace the adjacent wales 1.
  • These together form a ground portion 12.
  • this ground portion 12 formed of the ground yarns 11 there are formed through holes or meshes 14.
  • the mesh 14 will be formed differently, depending on a course pitch by which the weft yarn 5 is inserted.
  • the fabric may be expanded to the maximum length assumed by this fabric during the knitting operation.
  • a primary object of the present invention is to solve the above-described problem of the prior art by providing an improved lace fabric and a manufacturing method thereof which makes it readily possible to increase the amount of elastic contraction without such inconvenience.
  • a plurality of elastic yarns are knitted with each one of at least some of the plurality of wales, with each elastic yarn being knitted under a threading tension which ranges between about 1.0 and 2.5 times as strong as a threading tension of the ground yarns.
  • a plurality of elastic yarns are knitted with the single wale. Then, the elastic yarns may be engaged on the plurality of respective guide bars without significantly increasing the threading tension to be applied by each guide bar to each elastic yarn.
  • the threading tension of each guide bar may be not much different from that of the guide bar of a conventional machine.
  • a plurality of thin elastic yarns may be used in place of a single thick elastic yarn. So that, the threading tension of each thin elastic yarn may be maintained within a range of about 1.0 to 2.5 times as strong as the threading tension of the ground yarns. Accordingly, each elastic-yarn threading guide bar is not subjected to excessive load, and there occurs no disadvantageous effect on the durability of the machine.
  • the elastic contraction amount available from the lace fabric may be readily increased without deteriorating the durability of the knitting machine.
  • the plurality of elastic yarns are knitted with each one of all of the wales. With this, it becomes possible to further increase the total elasticity available from the lace fabric.
  • At least two elastic yarns are knitted with each wale in such a manner that these elastic yarns cross each other within the wale.
  • the elastic yarn has a greater frictional surface resistance than the ground yarns and other yarns to be inserted into the fabric. Then, if the two elastic yarns are knitted with the wale in the mutually crossing manner as described above, the frictional resistance between the crossing elastic yarns may be advantageously utilized for preventing these elastic yarns, when released from the threading tension, from resiliently retreating into the fabric from a length-wise cut edge of the lace fabric. Still preferably, at least some of the mutually crossing portions of the elastic yarns are heat-fused to each other by heat applied in the course of a fishing step of the lace fabric. This may restrict above-described resilient retreating dislocation of the elastic yarns more effectively.
  • a plurality of elastic yarns are knitted with each one of at least some of the plurality of wales; and some of the elastic yarns are knitted across a plurality of wales at at least some of the courses of the fabric.
  • the lace fabric having the above construction advantageously obtains course-wise elasticity, i.e. the elasticity inter-wale direction, in addition to the wale-wise elasticity.
  • a method of manufacturing a lace fabric comprising a plurality of wales including a plurality of loops of warp yarns, with a weft yarn being inserted between a loop portion and a sinker portion of some of the loops so as to interconnect the loops of adjacent wales, the method comprising the step of:
  • a plurality of elastic yarns may be threaded by the plurality of respective guide bars without considerably changing the threading tension to be applied to each elastic yarn. Therefore, a lace fabric having stronger elasticity may be manufactured on the machine, without applying excessive load to guide bars of the machine. Moreover, it is not necessary to employ all elastic yarn having a significant thickness to achieve such strong elasticity.
  • the present invention has provided an improved lace fabric and a manufacturing method there for which may solve the problem of the prior art.
  • Fig. 1 shows a lace fabric relating to the first embodiment.
  • This lace fabric 10 does not differ from the conventional lace fabric with respect to a ground portion 12, an ornamental pattern portion 13 and a mesh 14. That is, warp yarns 2 form loops 3 and these loops 3 form a plurality of wales 1. Further, a weft yarn 5 is inserted between a loop portion 3a and a sinker portion 3b of some of the loops 3 so as to interconnect the adjacent wales 1. These warp yarns 2 and the weft yarns 5 knitted together form a ground portion 12.
  • the ground portion 12 also defines a through hole or mesh 14. The shape of this mesh 14 will differ, depending on e.g. variation in the course pitch by which the weft yarn 5 is inserted.
  • an inserting yarn 6 such as a pattern-forming yarn 6a is inserted together with the weft yarn 5, so that an ornamental pattern portion 13 is formed by the inserted pattern-forming yarn 6a.
  • the elastic yarns 4 which comprise rubber yarns or filaments, are knitted along the wale 1 among the loop portion 3a, the sinker portion 3b, the weft yarn 5 and the inserting yarn 6.
  • Each of the elastic yarns 4 is knitted under an expanded condition with a threading tension which is set to be about 1.0 to 2.5 times as strong as a threading tension of the ground yarn, i.e. the warp yarn 2 or the weft yarn 5.
  • the warp yarn 2, the weft yarn 5 and the pattern-forming yarn 6a are knitted together with the elastic yarns 4 while these elastic yarns 4 are maintained under the expanded condition.
  • the elasticity of the elastic yarns 4 provides elasticity to the lace fabric 10.
  • the elastic yarns 4 include a first elastic yarn 4a and a second elastic yarn 4b.
  • the first elastic yarn 4a is inserted between the loop portion 3a and the sinker portion 3b of each and every loop 3 of the wale.
  • the second elastic yarn 4b is inserted between the loop portion 3a and the sinker portion 3b of some of the loops 3 intermittently.
  • the knitted fabric includes three types of loops 3; namely, one type in which the first and second elastic yarns 4a, 4b are inserted along one same direction, another type in which these yarns 4a, 4b are inserted in the mutually crossing directions, and the other type in which only the first elastic yarn 4a is inserted.
  • the elastic yarns 4 should be knitted with varying the pattern of insertion between the first elastic yarn 4a and the second elastic yarn 4b relative to each other. Therefore, these elastic yarns 4a, 4b are threaded by different guide bars. In this way, although the number of elastic yarns to be knitted is increased, the threading tension to be applied to each of the two elastic yarns may be maintained small so as to avoid applying excessive load to each guide bar.
  • Fig. 2 shows a lace fabric according to a second preferred embodiment of the present invention.
  • This lace fabric 10 does not differ from that of the first embodiment with respect to the ground portion 12, the ornamental pattern portion 13 and the mesh 14.
  • the warp yarns 2 form loops 3 and these loops 3 form a plurality of wales 1.
  • a weft yarn 5 is inserted between a loop portion 3a and a sinker portion 3b of some of the loops 3 so as to interconnect the adjacent wales 1.
  • These interconnected warp yarns 2 and the weft yarns 5 together form the ground portion 12.
  • the ground portion 12 also defines the through hole or mesh 14.
  • the shape of this mesh 14 will differ, depending on e.g.
  • an inserting yarn 6 such as a pattern-forming yarn 6a is inserted together with the weft yarn 5, so that an ornamental pattern portion 13 is formed by the inserted pattern-forming yarn 6a.
  • elastic yarns 4 which comprise rubber yarns or filaments, are inserted under an expanded condition along the wale 1 among the loop portion 3a, the sinker portion 3b, the weft yarn 5 and the inserting yarn 6.
  • the warp yarn 2, the weft yarn 5 and the pattern-forming yarn 6a are knitted together with the elastic yarns 4 while these elastic yarn 4 are maintained under the expanded condition.
  • the elasticity of the elastic yarns 4 provides elasticity to the lace fabric 10.
  • the elastic yarns 4 include a first elastic yarn 4a and a second elastic yarn 4b.
  • the first elastic yarn 4a is inserted between the loop portion 3a and the sinker portion 3b of each and every loop 3 of the wale.
  • the second elastic yarn 4b in this embodiment, is inserted from one loop of one wale 1 to an adjacent loop of an adjacent wale 1 in one course 7 and then reversely from the loop of this adjacent wale to another loop of the original wale in a subsequent course 7.
  • This running pattern of the second elastic yarn 4b is repeated with a skipping interval of two courses therebetween. And, in these two skipped courses 7, the second elastic yarn 4b is not inserted into the loops 3.
  • the first elastic yarn 4a is knitted and inserted between the loop portion 3a and the sinker portion 3b of each and every loop 3; and the second elastic yarn 4b is inserted in the same manner as above with the two-course skipping interval therebetween.
  • the first and second elastic yarns 4a, 4b at least the first elastic yarn 4a is inserted and knitted into the loops 3 along the longitudinal direction of the wale 1.
  • the second elastic yarn 4b too is inserted under the longitudinally expanded condition.
  • the lace fabric 10 of this embodiment has the wale-wise elasticity, i.e. the elasticity in the longitudinal direction of the wales 1 like the fabric of the first embodiment.
  • the fabric of this second embodiment also has the course-wise elasticity, i.e. in the width direction of the lace fabric 10.
  • the first and second elastic yarns 4a, 4b are to be knitted in patterns differing from each other as described above.
  • these elastic yarns 4a, 4b are threaded independently by different guide bars.
  • this second elastic yarn 4b is threaded by two guide bars.
  • the construction of this embodiment requires an even greater number of guide bars, the construction has the same advantage as that provided by the construction of the first embodiment; namely, that the threading tension applied to each of the two kinds of elastic yarns 4a, 4b does not result in application of excessive load to the guide bar.
