Definitions

  • the invention relates to a process for the production of thin compression crimped cables made of LOY, POY or FOY filaments and their further processing into hygiene articles such as diapers, sanitary napkins, insoles, also panty liners, incontinence pads u. like.
  • the Stauchk syndromesel compiler is mainly used in the production of staple fibers. To do this, first make as thick as possible cable by, for example, deducting several bundles of fibers from cans, combined to form a cable and together supplies a stuffer box, as for example in the EP 0 139 832 B1 is disclosed.
  • the total thickness of the cables is up to 4,000,000 dtex.
  • stuffer box crimping devices are required, such as. B. in the EP 0 139 832 B1 and DE 34 40 975 A1 described.
  • Absorbent hygiene articles usually contain so-called "acquisition layer", which consists of fibrous nonwoven material, such as. As a carded nonwoven fabric.
  • acquisition layer which consists of fibrous nonwoven material, such as.
  • fibrous nonwoven material such as.
  • carded nonwoven fabric As a carded nonwoven fabric.
  • this absorbent fiber layer is formed from a thin continuous filament tow.
  • the object of the invention is therefore to provide a method that works economically and simply, with which it is possible to selectively adjust the total titer of the crimped cable to the respective needs during further processing, which can be adjusted to the cable thicknesses, the immediate be required in a directly downstream processing process to which a further processing process can be connected on-line and leads to cables that are particularly suitable for the production of textile hygiene articles.
  • the upsetting crimping is performed at a speed of 300 to 500 m / min.
  • melt-spun polyester filaments are particularly advantageous in the context of the invention.
  • multi-component filaments in particular bicomponent filaments.
  • two or more types of filaments are used which have different properties.
  • Another object is the use of the above-described cable for the production of textile hygiene articles, in particular in an on-line method.
  • the implementation of the method according to the invention can be carried out, for example, in the following manner.
  • the LOY, POY or FOY filament yarns used as starting material can be prepared by methods known per se. References to such processes can be found, for example, in the article by H. Treptow in Man-made Fibers / Textile Industry, June 1985, pages 411 and 412.
  • LOY yarns are low oriented yarns
  • POY yarns are partially oriented yarns
  • FOY is fully oriented yarn.
  • these filament yarns are wound up individually on spools.
  • the titer of these filament yarns is suitably within a range of 30 to 300 dtex.
  • the titer of the individual filaments is preferably 1 to 16 dtex, in particular 3 to 10 dtex.
  • the number of coils used depends on the titer the compression crimped cable to be produced is to have. By simple calculation, it is possible to determine the required number of coils depending on the denier of the filament yarn. When calculating, take into account that the yarns may still be stretched.
  • the filament yarns are then stapled and then provided with a preparation.
  • This preparation supports the cable termination (cohesion of the filaments inside the cable) and must be selected according to the intended use of the cable. For example, use in the hygienic field requires special preparations approved for it.
  • the protective twist or the swirling of the filament yarns, which serve the cohesion of the yarns, should be as low as possible. It is only a flawless process to ensure the coils presented in the gate. After the fold, a homogeneous cable is to be created from the individual filament yarns. Too high a rotation or turbulence of the individual filament yarns would be a hindrance.
  • the plied and provided with a preparation filament yarns are then fed to a two drafting stretching device, wherein the first drafting system with temperatures between 30 ° C and 70 ° C and the second drafting system with godet temperatures between 100 ° C and 190 ° C is driven ,
  • drawing takes place here adapted to the desired yarn properties, the draw ratio decreasing with increasing preorientation of the yarns.
  • FOY yarns it is not absolutely necessary to stretch, so that only a comparison of the stress state is carried out within the stretching device by means of a slight tensioning delay (preferably between 1% and 2%).
  • the heating in the stretching device serves at the same time as a precursor to the main heating taking place subsequently in the heating device. Due to this main heating with approx. 100 ° C low pressure steam, the filaments are soft and flexible for the subsequent crimping process.
  • the cable After leaving the heater, the cable is fed to a Stauchk syndromeselmaschine and there compressive crimping. It is expedient to perform the upsetting crimping at a speed of 300 to 800 m / min. It is advantageous to perform the upsetting crimping in such a way that about 3 to 5 sheets per cm filament arise.
  • polyester filament yarns in particular yarns based on polyethylene terephthalate, polybutylene terephthalate, polytetramethylene terephthalate and the like. ä.
  • multicomponent in particular bicomponent filaments.
  • the multicomponent yarns, especially the bicomponent yarns may be core-sheath type or side-by-side bicomponent fibers.
  • the filament yarns used consist of filaments of different properties.
  • so-called hybrid filament yarns i. Yarns, for example polyester yarns, in which filaments of polyesters with different melting points are present.
  • the crimped cable After leaving the crimping machine, the crimped cable can be placed on a conveyor belt and stored in boxes or bales and stored and then shipped.
  • the crimped cables are directly forwarded, in particular on-line, to a further processing process.
  • the cables are advantageously processed into sanitary articles with a textile structure, such as diapers, sanitary napkins, insoles, incontinence pads, etc.
  • FIG. 1 serves to illustrate the invention.
  • FIG. 1 the process of the invention is shown schematically.
  • a creel 1 On a creel 1, a series of coils are mounted on which filament yarns are wound. The filament yarns are withdrawn from the bobbins on the creel, gefacht and provided in the device 2 with a preparation.
  • the device 2 may be a bath through which the plied yarns are drawn, but it is also possible to use a spray box or corresponding rolls or preparation godets.
  • the filament yarn cable provided with a preparation is then fed to a stretching apparatus which consists of two drafting units 3 and 4.
  • the yarns are drawn, the drawing, which is carried out in particular for LOY and POY yarns, being adjusted to the desired properties, such as strength and elongation.
  • the drawing device can also take place a homogenization of the tension by a small tensioning distortion.
  • the cable is passed through a heater in which the filaments are heated to the temperature necessary for crimping. This heating can be done for example by steam but also by dry heat.
  • the cable is fed to a Stauchk syndromeselmaschine in which the cable is compressed, it is expedient to apply 3 to 5 sheets per cm.
  • the experiment with FOY was performed in comparison to POY with adjusted settings.
  • the fundamental difference lies in a lower number of spools of 210, a non-performed drawing and a lower temperature of 112 ° C in the second rolls.
  • the process speed was 170 m / min. set.
  • the total cable thickness was 3.5 ktex.
  • the titers required for the further processing can be obtained in a simple manner by means of the method according to the invention.
  • the process is very flexible and is particularly suitable for companies that want to perform upsetting crimping and further processing in one operation.
  • the method makes it possible to easily produce cables with different titers and to supply the total titers required for the respective further processing process.
