Definitions

  • abrasive web with a woven backing made of synthetic fibers.
  • abrasive web is understood to mean bound abrasives according to "Ullmanns Encyclopedia of Technical Chemistry, Vol. 20, pp. 449 ff".
  • polyester abrasives of this type are characterized, among other things, by low water absorption and are therefore particularly suitable for wet grinding. They also have high strength, both tear and tear resistance, which enables a long service life.
  • a critical point of such abrasives can be the adhesion between the backing material and the binder.
  • DE-OS 25 31 602 it is therefore recommended not to manufacture the carrier material from filament yarn, but from fiber yarn, despite the greater strength.
  • the object of the present invention is to provide an abrasive with a woven backing material made of synthetic filament yarns, which is not inferior to a backing material made from fiber yarns with regard to the adhesion between the binder and the backing material. This task also includes its manufacture.
  • the carrier material made of filament yarn consists of fully or partially split multicomponent fibers of the matrix segment type.
  • multi-component fibers of the matrix segment type are to be understood as fibers which are composed of at least two different components which are essentially incompatible with one another, for example polyester and polyamide.
  • the matrix is the component in which the segments are more or less embedded. It can happen that the matrix completely envelops the segments or that the segments are only partially surrounded by the matrix. Both the matrix and the segments are arranged continuously with a substantially constant cross section over the entire length of the fiber.
  • Multi-component fibers of the matrix segment type which have at least three peripheral segments are preferably used in the context of the invention, at least some of the peripheral segments not being encased by the matrix, that is to say making up part of the edge of the cross section.
  • Cross sections according to FIGS. 1 to 4 have peripheral segments with rounded surface parts, whereas cross sections, as shown in FIG. 6, have, in addition to a rounded part at the edge of the cross section, also substantially straight parts of the surface.
  • Cross sections according to FIG. 6 are also referred to as an orange profile.
  • the cross section shown in Figure 6 is also called the six-member.
  • Cross sections according to Figures 1 to 4 are also referred to as so-called gear profiles, with Figures 2 to 4 being so-called six-gear profiles.
  • FIG. 3 also has an additional central segment, in FIG. 4 there are three further segments completely encased by the matrix.
  • FIG. 7 An asymmetrical and uneven arrangement of segments and the matrix is shown in FIG. 7.
  • the matrix consists of polyamide and the peripheral segments of polyester.
  • FIG. 8 shows cross sections of split filaments. The individual segments are completely separate.
  • Figure 9 are cross section of filaments shown that are only partially split.
  • the fully or partially split filament yarn is woven, finished and further processed into abrasives using known methods.
  • FIG. 10 shows a schematic cross section through the abrasive: a) is the abrasive grain, b) the binder and c) the woven backing material.
  • a preferred embodiment of the invention is the elastically bound abrasive. It is preferably used in the form of endless flexible abrasive belts. But it can also be used in the form of rolls, sheets and strips. It will be explained in more detail by the following examples:
  • the abrasive produced in this way showed, after grinding samples in the next higher grain area, a much better adhesion between the carrier material and the binder when visually assessed than a comparison abrasive made of textured polyethylene terephthalate (diols) of the same titer (400 dtex).
  • the grain, including the coating, was broken out less frequently.
  • the abrasive according to the invention even withstood a comparison in this regard with an abrasive made from polyester fiber yarn.
  • Example 1 was repeated with the exception that the total titer was now 200 dtex. The results were practically the same.
