Definitions

  • Patent literature relating to nonwoven textiles formed by combinations of fibres and continuous filaments describes various mechanical, chemical and thermal methods of combining fibres and filaments and consolidating the fibrous matting. These include:
  • the subject of the invention is a nonwoven textile and a method of producing it as defined in the following claims.
  • a carding machine schematically indicated 1, supplies a fibrous web 4 to a folding device 2.
  • a supply device 3, carrying reels 5 of filaments B, is associated with the folding device 2.
  • the filaments B are fed continuously onto the fibrous web 4 as it advances in the direction indicated by the arrow F so that a mat 6 of fibres and filaments is formed during the folding and is then subjected to known consolidating steps, not shown.
  • the devices which supply the filaments may be arranged as shown in Figure 2A, Figure 2B or Figure 2C, that is:
  • the final product produced by such a method of mixing can fully satisfy various users' requirements in the sense that simply by varying the percentages of the basic components - the fibres and the filaments - used in the mixing of the starting textiles, the product can be transformed from a weak, deformable material into a strong material with low deformability or, if a variation in the nature of the polymers used is also adopted, into a material with controlled degradability.
  • the fibres A may be selected from:
  • the components both of type A1 and of type A2 may be of a single denier or may be mixtures of fibres of various deniers.
  • the filaments B may be:
  • the components A and B may be mixed so as to be oriented in one or both production directions (longitudinally and transversely) or in a disordered manner which takes no account of the production direction, but the distribution of the components A and B per unit area must in any case be uniform.
  • the percentages of the components A and B in the mixture of the product must be at least 15% of the final mass per unit area for the type A components and at least 1% for the type B components, that is, from 15% A + 85% B to 99% A + 1% B.
  • the mixture of the components A and B may be consolidated by mechanical or thermal means. After the nonwoven fabric with continuous filaments has been produced, the product may undergo further mechanical, chemical or thermal treatments, according to the user's requirements, or may undergo a further operative step if it is to be used as a component part of a composite or special material.
