Definitions

  • the invention relates to the use of textured yarns made from polyester filaments in the manufacture of coated abrasives.
  • Coated abrasive is the common term used in the abrasive industry for the numerous products that consist of a flexible pad coated with abrasive grain. It corresponds to the term “coated abrasives” used in the English-speaking world.
  • DE-PS-3 218 441 mentions various types of filament yarns which can be used for the production of a base fabric which serves as a base.
  • the yarns can consist of filaments that have a profiled, e.g. B. have a triangular cross-section, there is also talk of fibers that have lateral extensions as spacers, without explaining how these lateral extensions should be designed. There is also talk of crimped polyester filament yarns without specifying process conditions for how to perform the crimp.
  • Example 1 speaks generally of a hot air process, without further details being given.
  • filament textured yarns have disadvantages for the production of underlays because numerous loops solidified with impregnating compound protrude from the surface, so that, as usual, abrasives produced lose the binder grain layer after a few minutes of grinding time.
  • the yarns are blasdüsentexturiert and thermally stabilized and have loops and arcs, of which at least a part freely outstanding loops and coils are .
  • the yarns used preferably have between 10 and 80 freely protruding loops and bows per running cm of yarn.
  • the loops and bows can be partially opened to form freely protruding fiber ends.
  • the hot air shrinkage of the yarns is preferably at most 6%, in particular at most 2%.
  • the boiling shrinkage of the filament yarns is preferably at most 0.5 to 4%.
  • yarns are used which have been subjected to false twist texturing with a low number of turns before texturing the blow nozzle and which have been blown cold and fixed hot after the false twist texturing.
  • Such yarns expediently have a total titer of 100 to 1200 dtex and have been subjected to false twist texturing at 1200 to 1800 revolutions / minute and have been subjected to fixation in the temperature range from 180 to 225 ° C. during the false twist texturing.
  • Such yarns can advantageously be used to build up the fabric serving as a base untwisted or with a protective twist of 80 to 400 turns / meter.
  • yarns are used which are characterized in that the yarns textured with the blowing nozzle are fed in before being stabilized by means of one or more rollers which are rotatably mounted one behind the other in the course of the thread at least one turn, so that the thread bundle fed to the rolls covers the thread bundle running off the rolls at least in its edge region and thereby clamps the loops and arches of the running thread bundle projecting over the thread run, with freely protruding fiber ends being formed.
  • the rollers rotatably mounted one behind the other can have rough surfaces.
  • Woven underlays are very suitable for the abrasives in the context of the invention. It is also advantageous if the base is a pile fabric, in particular a sewn pile fabric.
  • the yarns used according to the invention can contain filament mixtures of different titers or different cross sections.
  • Blasdüsentexturiere yarns of polyester filaments as they come within the scope of the invention for use are prepared by means of a texturing operating according to the Lucasstra h lpal texturing.
  • blower-textured yarns are e.g. B. in the magazine chemical fibers / textile industry, October 1975, pages 929 ff.
  • Blow-jet-textured yarns made of polyester filaments are preferably used in the context of the invention, which have been textured by the process described in DE-OS-27 49 867.
  • the disclosure in this published specification is expressly referred to here.
  • this method which is used to produce a crimped yarn from multifilament continuous fibers, in which the yarn is passed between a first and a second driven delivery unit through a texturing nozzle working according to the air jet principle, the peripheral speed V 2 of the second delivery unit being less than the peripheral speed V, the first supplier and where the yarn is wound up after texturing and heat treatment, the yarn is subjected to a heat-free warping which does not lead to elastic or plastic deformations immediately after leaving the texturing zone in a stabilizing zone and the yarn immediately afterwards Stabilizing zone of a fixing zone with a shrink and heat treatment up to 245 ° C at a peripheral speed of the output supply of the fixing zone of V 4 ⁇ V, fed and the yarn with a predetermined thread tension and a winding speed V
  • the yarns textured according to the process described in DE-OS-27 49 867 have loops and arches which partially protrude beyond the thread periphery. As such, if they are appropriately stabilized, such yarns can be used in accordance with the invention.
  • these blower-textured threads are preferably guided at least in one turn by way of one or more rotatable rollers mounted one behind the other in the thread path.
  • the supplied bundle of threads must be the one from the. Cover the bundle of rolls running off at least in its edge area and clamp the loops and arches of the running bundle of thread protruding above the core of the thread onto the roll; part of the loops and arches that are clamped open, i. H. torn.
  • the yarns treated in this way are then subjected to thermal stabilization.
  • a corresponding thermal stabilization can also be used for yarns textured with blower nozzles which have not been treated in accordance with DE-OS-27 49 867.
  • the polyester filament yarns are subjected to false twist texturing with a low number of turns before the blowing nozzle texturing.
  • low number of turns means a number of turns that is below the number of turns, as is usually used in false twist texturing.
  • the most appropriate number of turns depends on the total titer of the yarn to be treated. For total titers from 100 to 1200 dtex, tours from 1200 to 1800 are preferred.
  • a temperature of 180 to 225 ° C. is preferably maintained in the fixing zone during false twist texturing.
  • the false twist textured yarns are then blown cold and then fixed in a manner as already mentioned above.
  • Underlay in the sense of the invention are fabrics such as nonwovens, woven fabrics, knitted fabrics and the like. to understand, which can be coated with conventional abrasive grains using appropriate adhesive and, if necessary, other conventional additives.
  • the documents can be as sheets, strips, mats and the like. be opened. But you can also from a specially made sheet, e.g. B. a disc or the like. consist.
  • yarns When using the yarns in fabrics for the backing in the manufacture of abrasives, yarns can be the same or different titer in warp and weft. In principle, the fabrics can be constructed in the usual weaves.
  • the weight of the fabric can e.g. B. 150 to 500 g / m 2 .
  • the underlay consists of a single textile fabric, e.g. B. a tissue.
  • a single textile fabric e.g. B. a tissue.
  • two or more types of fabrics e.g. B. connect fleece and fabric with each other.
  • the yarns are used in documents in the form of a pile fabric.
  • pile fabric is to be understood in general a textile fabric, in which the yarns have elevations due to their processing, as it is for B. is the case with tufted material.
  • These poles can be closed or open.
  • Suitable presentations of polar articles which can be used as a base in the production of abrasives and in which the yarns can be used according to the invention, are mentioned for example in the German utility model, roll number 82 37 962 on page 4. The disclosure in this German utility model is expressly referred to here.
  • Sewn knitted documents or documents with a corresponding weft entry are very suitable.
  • Malimo, Malipol and Maliwatt goods are expressly mentioned here.
  • the documents are characterized by a smooth surface, which is particularly noticeable in the finished abrasives in the form of flat surfaces, so that the abrasives have a long service life during use and do not have the disadvantages described above.
  • the use according to the invention on the one hand achieves the advantages which are otherwise generally achieved with fiber yarns, i.e. H. achieved with staple fiber yarns, on the other hand, a number of advantages that are only obtained with filament yarns are also achieved.
  • the base Due to the special structure of the yarns, the base is very absorbent for the binder, so that the binder can also penetrate into the interior of the base, thus ensuring that grain adheres well to the base.
  • the documents have the required mechanical properties, in particular strength, tear resistance, low reference elongation, especially for fabrics.
  • the abrasives which are accessible through the use of yarns according to the invention, can be used for both wet and dry grinding.
