Definitions
- the present invention relates to a method for drawing a pre-oriented multifilament yarn (POY yarn) with the features of the preamble of claim 1.
- POY yarn pre-oriented multifilament yarns
- a main draw zone the main draw zone having a delivery godet and a take-off godet.
- the multifilament yarn is looped around both the delivery godet and the take-off godet, so that there are two clamping points between which the multifilament yarn is drawn.
- a heated pin is also arranged in the known main stretching zone, which is also wrapped in the yarn.
- the multifilament yarn to be drawn is drawn at a first speed fed to the main stretching zone and withdrawn from there at a second speed from the main stretching zone, the second speed in the known device being up to about 60% higher than the first speed, so that a corresponding tensile stress is exerted on the multifilament yarn.
- a further increase in the take-off speed is not possible in the known device, since otherwise breaks in individual filaments occur, which lead to permanent damage to the drawn multifilament yarn.
- EP-A 0 119 044 A method with the features of the preamble of claim 1 is known from EP-A 0 119 044.
- a pre-oriented multifilament yarn (POY yarn) is used as the starting material, which is drawn exclusively in a main stretching zone consisting of a delivery godet wrapped in the yarn and a take-off godet wrapped in the yarn.
- EP-A 0 119 044 expressly points out that in the known method the draw ratio varies between 1: 1.45 and 1: 1.6, the known drawing of the pre-oriented multifilament yarn (POY yarn) being carried out exclusively in the cold in order to trigger a high shrinkage in the thermal treatment carried out after stretching.
- the present invention has for its object to provide a method for drawing a multifilament yarn in which no filament breaks occur even at higher take-off speeds (second speed).
- the multifilament yarn to be drawn is fed at a first speed to the main stretching zone via a delivery godet wrapped in the yarn and drawn off from the main stretching zone at a second speed via a take-off godet wrapped around the yarn.
- the second speed is greater than the first speed.
- the take-off godet is heated to a temperature between 160 ° C.
- the first and second speeds being matched to one another in such a way that the second speed is 70% to 180% greater than the first speed. This ensures that the pre-oriented multifilament yarn (POY yarn) to be drawn is thus drawn with a draw ratio of 1: 1.7 to 1: 2.8 in the process according to the invention.
- the POY yarns in particular polyester POY yarns
- this is attributed to the fact that the known heated stretching pin in the main stretching zone or the known cold stretching are deliberately dispensed with here.
- the multifilament yarns drawn in this way also surprisingly have relatively low shrinkage values, in particular boil-off shrinkage values (water 98 ° C.) of less than 1% and hot air shrinkage values at 160 ° C. less than 1.5%.
- the multifilament yarns drawn by the process according to the invention have a tensile strength which is between 20% and 80% higher than the tensile strengths with identical starting materials can be achieved by using the conventional method described above.
- a first, particularly suitable embodiment of the method according to the invention provides that here the first and second speeds are coordinated with one another in such a way that the second speed is 100% to 160% greater than the first speed.
- degrees of stretching are used which vary between 1: 2 and 1: 2.6.
- the multifilament yarns stretched in this way which are preferably polyester multifilament yarns, are distinguished by even lower shrinkage values, in particular by boiling shrinkage values (water 98 ° C.) of less than 0.8% and heat shrinkage values (160 ° C.) of less than 1.2%. , out.
- the tensile strengths of the multifilament yarns drawn in this way are also higher by approximately 60% to 80% compared to conventionally drawn multifilament yarns.
- Another embodiment of the process according to the invention provides that the delivery godet is also heated to a temperature between 60 ° C. and 160 ° C., preferably to a temperature between 80 ° C. and 140 ° C.
- a further embodiment of the method according to the invention provides that the multifilament yarn to be drawn is heated to a temperature between 80 ° C. and 180 ° C. in the main drawing zone, ie between the delivery godet and the take-off godet. This will heat up the stretched Multifilament yarns carried out in the main stretching zone in such a way that a hot plate, an IR radiator and / or a laser are used for this purpose.
- this residence time varies in particular between 0.01 s and 1 s.
- the delivery godet and the take-off godet are looped around with the multifilament yarn to be drawn, as already described above. It has been shown here that particularly high strengths and particularly low shrinkage values result when the delivery godet and / or the take-off godet is wrapped 5 to 40 times, preferably 10 to 20 times, with the multifilament yarn to be drawn. These wrapping values relate to godets whose diameters vary between approximately 40 mm and 250 mm, preferably 80 mm and 120 mm.
- Another, particularly suitable embodiment of the method according to the invention provides that, seen in the direction of transport of the multifilament yarn to be drawn, a pre-drawing zone is arranged in front of the main drawing zone.
- the multifilament yarn (POY yarn) to be drawn is first partially in the pre-drawing zone stretched and then finally stretched in the main stretching zone.
- the multifilament yarn in the pre-stretching zone between 0.5% and 10%, preferably between 1% and 4%.
- the multifilament yarn is thus stretched in the pre-stretching zone between 0.5% and 10%, preferably between 1% and 4%.
- pre-stretching or stretching speeds it should be noted that the aforementioned high strengths and low shrinkage values can be achieved particularly economically and reproducibly if one selects take-off speeds that are preferably between 600 m / min and 1,200 m / min.
- a relaxation zone is arranged behind the main drawing zone, in which the drawn multifilament yarn is heated to a temperature between 80 ° C and 240 ° C, preferably to a temperature between 140 ° C and 200 ° C, is heated. It has been shown here that such a relaxation zone further reduces the aforementioned shrinkage values of the drawn multifilament yarn by about 20% to about 40%, in particular when the drawn multifilament yarn is introduced into the relaxation zone with lead, which is preferably between 0.5% and 10% and in particular between 1% and 3%.
- the residence time of the multifilament yarn in the relaxation zone then varies depending on the respective transport speed of the yarn through the relaxation zone and is preferably 0.01 s to 1 s.
- the selection of the multifilament yarn (POY yarn) to be drawn by the method according to the invention is based on the later use of this drawn yarn. If, for example, the drawn yarn is later processed into a sewing thread, it is advisable to select such a POY multifilament thread whose single-filament titer as the starting material varies between 1 dtex and 12 dtex, preferably between 1.5 dtex and 4 dtex.
- the total titer of the POY yarn to be drawn in each case also depends on the later use of the drawn yarn. For use of the drawn yarn to produce a sewing thread, this total titer of the yarn to be drawn varies between 40 dtex and 2,000 dtex, preferably between 80 dtex and 1,200 dtex.
- a POY yarn is used for this which has a number of filaments between 16 and 300, preferably between 24 and 96.
- a particularly suitable embodiment of the method according to the invention provides that the pre-oriented multifilament yarn to be drawn is a polyester POY yarn, as has already been mentioned several times above.
- a polyester POY yarn is used as the starting material, the intrinsic viscosity of which is between 0.5 dl / g and 0.75 dl / g, preferably between 0.55 dl / g and 0.63 dl / g.
- high-strength multifilament yarns can be made from a textile standard multifilament yarn without it being necessary, as in the current state of the art, for example to increase the molecular weights of the polymer or to vary the monomers.
- the method according to the invention can in particular also be used to produce preliminary products for the production of sewing threads.
- the multifilament yarn stretched according to the invention is processed as core material in a core yarn, in which case this core yarn itself or two to four core yarns form a sewing yarn, as is described in detail in DE-A-4 215 212.
- a particularly suitable development of the method according to the invention described above, which is used in particular for the production of sewing threads, provides that after the stretching, the stretched multifilament thread with at least one second multifilament thread with formation of a thread provided with loops and loops in a turbulent fluid stream, in particular one Gas flow, swirled.
- a swirled core-sheath yarn thus arises, the multifilament yarn drawn by the method according to the invention being arranged in the core (core), while the sheath (effect material) is formed by the at least one second multifilament yarn.
- Such a sewing thread which preferably consists of polyester multifilaments, then has strengths as the finished product, which are preferably between 40 cN / tex and 60 cN / tex, the residual shrinkage of the finished thread preferably being less than 2% (thermal shrinkage 160 ° C.) or less than 1.2% (boiling water shrinkage 98 ° C).
- a swirled sewing thread has an excellent sewing behavior, which is expressed by the fact that it is extremely difficult Sewing operations, such as multidirectional sewing at up to 7,000 stitches per minute or buttonhole sewing, do not tear or cause other disruptions when sewing.
- such a sewing thread can also be excellently dyed in terms of color and color uniformity, which is attributed to the fact that this sewing thread has a specially stretched multifilament thread as the core material, but otherwise corresponds in its molecular structure to a standard textile fiber.
- the drawn multifilament yarn is led with a lead of between 1% and 7% and the second multifilament yarn forming the effect material with an advance of between 15% and 45% of the intermingling.
- the stretched multifilament yarn is also wetted with water or an aqueous dispersion before intermingling, this causes the core material to be mixed particularly intensively with the effect material, so that this also results in an increase in thread closure.
- such for the second multifilament yarn Material is selected whose titer is 15% to 40% and whose number of filaments is 30% to 250%, in each case based on the titer or the number of filaments of the multifilament yarn forming the core (first yarn component) of the core-sheath yarn.
- a pre-oriented multifilament yarn (POY yarn) is also used as the second multifilament yarn.
- This pre-oriented multifilament yarn which, like the stretched multifilament yarn used as the core, consists of polyester, can either be drawn according to the conventional method described at the beginning of the prior art, or preferably also drawn as described in detail above in the various embodiments of the method according to the invention is.
- the variants described at the beginning of the process according to the invention which relate to the temperature range of the delivery godet, to the heating of the multifilament yarn in the main stretching zone, to the times during heating, to the wrapping of the delivery godet and / or the take-off godet, to the arrangement of a pre-stretching zone, to the Leading in the pre-drawing zone, the drawing speed, the arrangement of a relaxation zone, the leading in the relaxation zone and the selection of the intrinsic viscosity of the yarn used can also be used identically for the drawing of the second multifilament yarn (fancy yarn), so that in order to avoid repetition, reference is made to the design variants described in detail above.
- the multifilament yarn forming the core of the core-sheath yarn and the multifilament yarn forming the sheath of the core-sheath yarn are drawn identically, so that the intermingled core-sheath yarn produced therefrom is characterized in particular by this that it stains identically both from the hue and from the depth of color.
- a further, particularly suitable embodiment of the method according to the invention provides that one to four multifilament yarns forming the core of the intermingled core-sheath yarn and drawn according to the stretching methods described at the beginning with one to four, the sheath component of the intermingled core-sheath yarn forming multifilament yarn or forming yarn swirled.
- the intermingled core-sheath yarn after the intermingling with a twist of between 10 turns per meter and 1,000 turns per meter, preferably between 100 Turns per meter and 600 turns per meter.
- a further embodiment variant of the method according to the invention provides that the intermingled core-sheath yarn is subjected to a tension treatment so that the self-intersecting loops or loops formed during intermingling are reduced to such an extent that they become their diameter can be reduced by about 20% to about 95% of their original diameter.
- the volume of the intermingled yarn is reduced accordingly, so that such a Yarn has a reduced number of protruding loops and loops, so that these loops and loops get caught in the processing and in particular when such a yarn is used as a sewing thread.
- the intermingled core-jacket yarn is fed to the tension treatment at a rate which is between 0.1% and 5%, preferably between 0.1% and 2.5%, less than the rate, with which the interlaced yarn is withdrawn from the tension treatment.
- the reduction in the diameter of the loops or loops of the entangled yarn described above can be achieved by subjecting the entangled core-jacket yarn to thermal treatment at a temperature between 100 ° C. and 250 ° C., in particular between 180 ° C. and 240 ° C, subject.
- This thermal treatment is preferably carried out in a hot air stream, the times of the thermal treatment varying in particular between 0.01 s and 10 s, preferably between 0.05 s and 1 s.
- Such thermal treatment also serves to reduce the shrinkage values (cooking shrinkage - water, hot air shrinkage) of the intermingled core-sheath yarn.
- another embodiment of the method according to the invention provides that the intermingled yarn of the thermal Treatment at a rate higher than the rate at which the core-sheath yarn is removed from the thermal treatment.
- the core-sheath yarn is preferably fed to the thermal treatment at a speed which is 0.5% to 10%, in particular 1% to 3%, higher than the withdrawal speed of the core-sheath yarn from the thermal treatment.
- the core-sheath yarn can shrink freely during the thermal treatment, which in turn is expressed extremely positively in the residual shrinkage of the correspondingly treated core-sheath yarn.
- the method according to the invention is preferably used for polyester multifilaments, polyester being understood as meaning polyethylene terephthalate in the context of the present application.
- POY yarn partially oriented yarn or pre-oriented yarn used in the present text encompasses all pre-oriented polymeric multifilament yarns which have undergone a certain amount of pre-orientation in the course of their manufacturing process, but this size of the molecular pre-orientation does not correspond to the molecular orientation corresponds, which has a fully drawn multifilament yarn.
