Definitions

  • the present invention relates to a two-component loop sewing thread for modern industrial sewing machines with high strength and low shrinkage and a method for its production.
  • a similar loop sewing thread is known for example from EP-A 57 580.
  • several, differently shrinking yarns are fanned by air-jet texturing with different lead and thus a loop yarn is produced.
  • the shrinkage is triggered in a subsequent fixing process, the loops of the filaments are then tightened into bud-like projections.
  • the yarns are provided with a twist of about 100 to 300 T / m between loop formation and fixation.
  • a disadvantage of these known methods is that the final strength of the finished loop yarn is lower than would be expected from the strength of the rovings.
  • the final strength of these known sewing threads is only between 25 and 40 cN / tex, whereby final strength here means the quotient of the maximum tensile force and the final titer at the moment of tearing.
  • the filaments of these known yarns can also shrink to different degrees depending on the degree of integration. These differences can be seen in a different coloration along a filament and are particularly pronounced from filament to filament if yarns with different shrinking capacities have been used.
  • Single-component loop sewing threads are already known, the final strength of which is between 40 and 50 cN / tex.
  • these yarns have poor sewing properties due to their low number of loops.
  • they are provided with around 600 to 800 T / m and their elongation at break is relatively high at over 18%.
  • the present invention relates to a two-component loop sewing thread which does not have the disadvantages of the prior art described above.

  • the final strength is understood to be the quotient of maximum tensile force and final titer at the moment of tearing; the maximum tensile strength stretch is the elongation that the yarn experiences under the effect of the maximum tensile force.
  • the total titer of the two-component loop sewing thread according to the invention is generally 200 to 900 dtex. Underneath and overlying titers can also be produced if they are of interest in the individual application, but they are not the rule.
  • the two-component loop sewing thread according to the invention is composed of stand-up filaments and effect filaments.
  • the upright filaments are in the Oriented to a much greater extent in the direction of the fiber axis than the effect filaments, which are interwoven and intertwined with the upright filaments, but additionally form loops protruding from the fiber structure due to their greater length and thus have a significant influence on the textile and usage properties of the yarn according to the invention.
  • the total titers of upright filaments and effect filaments of the loop sewing thread according to the invention are in a ratio of 95: 5 to 70:30, preferably 90:10 to 80:20.
  • Stand-up filaments and effect filaments differ in terms of their individual titer. This is 8 to 1.2, preferably 5 to 1.5 dtex for the standing filaments, and 4.5 to 1, preferably 3 to 1.4 dtex for the effect filaments. Within these titer limits, the single titer of the standing filaments is 1.2 to 6 times, in particular 1.5 to 3.5 times, the single titer of the effect filaments.
  • the two-component loop sewing threads according to the invention can be produced from the above-mentioned synthetic spinnable polymers and polycondensation products such as polyamide, polyacrylonitrile, polypropylene and polyester.

B. phthalic acid or isophthalic acid, 1,4-, 1,5- or 2,6-naphthalenedicarboxylic acid, hydroxycarboxylic acids such as. B. para- (2-hydroxyethyl) benzoic acid and aliphatic diols with 2 to 6, preferably 2 to 4 carbon atoms such as.
  • B. ethylene glycol, 1,3-propanediol or 1,4-butanediol can be obtained by cocondensation.
  • This polyester Raw materials can also by condensing in smaller proportions of aliphatic dicarboxylic acids such as. B. glutaric acid, adipic acid or sebacic acid or of polyglycols such as. B. diethylene glycol (2,2-dihydroxydiethyl ether), triethylene glycol (1, 2-di (2-hydroxy-ethoxy) ethane) or modified by smaller proportions of higher molecular weight polyethylene glycols.
  • a further modification possibility which in particular influences the dyeing behavior of the two-component loop sewing threads according to the invention, is the modification by building blocks containing sulfo groups such as e.g. B. by the incorporation of sulfoisophthalic acid.
  • the upper limit of the final strength of the loop sewing threads according to the invention depends on the selected degree of condensation of the polymer material used, in particular the polyester material.
  • the degree of condensation of the polyester is expressed in its viscosity.
  • a high degree of condensation, i.e. H. a high viscosity leads to particularly high final strengths of the yarns according to the invention.
  • DCE dichloroacetic acid
  • a preferred polyester material for producing the loop yarns according to the invention is polyethylene terephthalate.
  • the two-component loop sewing thread according to the invention consisting of stand and effect filaments, is produced by air-jet texturing of two roving strands fed with different lead, these roving strands having different total and individual titer, but both consisting of high-strength, low-shrinkage and low-stretch filaments.
  • High-strength, low-shrinkage and low-elongation filaments are understood to mean those which have a maximum tensile strength, based on the final titer, of at least 65 cN / tex, generally 65 to 90 cN / tex, preferably 70 to 84 cN / tex, a maximum tensile strength Elongation of at least 8%, usually 8 to 15%, preferably 8.5 to 12%, and a thermal shrinkage at 180 ° C. of at most 9%, usually 5 to 9%, preferably 6 to 8% .
  • the filament material is fed to the blow nozzle at a higher speed than is drawn from it.
  • the two strands of yarn to be mixed which then deliver the stand or the effect filaments in the finished yarn, are fed to the texturing nozzle with different lead.
  • the roving strand, from which the upright filaments of the yarn according to the invention emerge, is fed to the blowing nozzle with a lead of 3 to 10%, the roving strand, from which the effect filaments of the yarn according to the invention emerge, with a lead of 10 to 60%.
  • the total titers of the roving strands forming the upright filaments and the effect filaments are selected so that they have a ratio of 95: 5 to 70:30, preferably 90: 10 to 80:20, and that their mixture after the interlacing is 200 to 900 dtex.
  • the total titer T S of the intermingled yarn is not simply composed of the titers of the roving, but that the leading of the two roving must be taken into account here.
  • the total titer T S results from the following formula where T St and V St are the titer and lead of the roving and T E and V E are the titer and the lead of the effect roving.
  • the individual titer of the filament of the roving is 8 to 1.2, preferably 5 to 1.5 dtex, the individual titer of the filament of the effect roving is 4.5 to 1, preferably 3 to 1.4 dtex.
  • the individual titer of the rovings is selected so that the individual titer of the upright filaments is 1.2 to 6 times, preferably 1.5 to 3.5 times, the individual titer of the effect filaments.
  • the high-strength and low-shrinkage yarns can be used, the z. B. from DE-AS 12 88 734 or EP-A 173 200 are known and their production is described there.
  • the rovings required for the process according to the invention are preferably produced in an integrated process step which precedes the air swirling, in which they are obtained by stretching a partially oriented spun fabric and an immediately subsequent, essentially shrink-free heat treatment.
  • substantially shrink-free means that the yarns are preferably kept at a constant length during the heat treatment, but that a shrinkage of up to 4%, better not over 2%, can be admitted.
  • two partially-oriented yarns with different total and single filament titers are drawn on separate drawing units, which are subjected to essentially shrink-free heat treatment and are then immediately fed to the air nozzle texturing.
  • the partially oriented yarns are drawn at a temperature of 70 to 100 ° C., preferably via heated godets, at a drawing tension in the range from 10 to 25 cN / tex, preferably from 12 to 17 cN / tex (in each case based on the drawn titer).
  • the essentially shrink-free heat treatment of the yarns immediately after stretching takes place at a yarn tension between 2 and 20 cN / tex, preferably at 4 to 17 cN / tex, and a temperature in the range from 180 to 250 ° C., preferably from 225 to 235 ° C.
  • this heat treatment can be carried out in any known manner; it is particularly expedient to carry out the heat treatment directly on a heated extraction godet.
  • the drawing conditions of the two partially oriented yarns are preferably kept as identical as possible. However, differences in the drawing conditions of up to ⁇ 10% can be tolerated.
  • the loop yarn withdrawn from the air texturing nozzle can still be subjected to a fixing process.
  • This fixation can also be carried out in any manner known per se, it is expedient to subject the yarn of constant length to hot air treatment at temperatures of 200 to 320 ° C., preferably 240 to 300 ° C.
  • the loops of the individual filaments remain fully intact and, thanks to the entrained air, result in good sewing properties even at high sewing speeds. This advantage is evident in the high values for the so-called sewing length to break, which are determined by the method known from DE-A-34 31 832.
  • the uniformly stretched filaments lead to uniform coloring and thus to a calm image of the seam.
  • the strength of the yarns produced in this way is significantly higher than that of sewing threads with differently shrinking filaments.
  • the use of similar rovings also simplifies the manufacturing process.
  • shrinking rovings for example, much more loops must first be produced than the finished sewing thread should have, since the shrinking process leads to a reduction in the number of loops.
  • the two-component loop sewing thread according to the invention does not have to be twisted during its manufacture. It is therefore untwisted and can also be used untwisted as a sewing thread. Usually, however, is subsequently in the course of further processing, eg. B. for optical reasons, a relatively weak rotation of about 100 to 300 T / m applied.
  • a device for the production of the two-component loop sewing thread according to the invention can be constructed, for example, from the following elements: a bobbin creel for the bobbins of the main and effect roving, two drafting units working in parallel with heatable inlet and outlet godets, a blowing nozzle with separate infeed units for the exact setting of the advance of the roving strands, a take-off unit for the defined take-off of the blown yarn, if desired a conventional hot air fixing device and a take-up reel.
  • a bobbin with stand roving with a titer of 380 dtex f40 (single filament titer: 9.5 dtex) and a bobbin with effect roving with a titer of 83 dtex f24 (single filament titer: 3.5 dtex) are placed on the creel. Both rovings consist of polyethylene terephthalate with an intrinsic viscosity of 0.68 dl / g, measured in DCE at 25 ° C.
  • the two rovings are fed to the drawing units assigned to them and drawn there at a temperature of the inlet godet of 90 ° C. in a ratio of 1: 2.
  • the draw tension was 15 cN / tex for the main roving and 14 cN / tex for the effect roving.
  • the drawn yarns were passed in 10 turns around the outlet godets of the drafting systems, which were heated to 230 ° C.
  • the yarn running speed for the two drafting units was adjusted separately so that the running speed into the blowing nozzle was 315 m / min for the main roving and 420 m / min for the effect roving.
  • the blown yarn was drawn off behind the blow nozzle at 300 m / min. This results in an advance of 5% (tradition 1.05) for the main yarn and 40% (tradition 1.40) for the fancy yarn.
  • the loop yarn was fixed by passing it through a 160 cm long hot air oven heated to 240 ° C.
  • the raw yarn thus obtained was wound up. It has a titer of 243 dtex / f64, a final strength of 50.7 cN / tex, a maximum tensile strength elongation of 9.8% and a heat shrinkage at 180 ° C of 3.1%.
  • its average sewing length is greater than 4,000 stitches when sewing forward and greater than 2,000 stitches when sewing backward.
