Definitions

  • the present invention concerns the field of so-called “dust-collecting” textile products, i.e. that are able to hold dust and due to this property are intended for dusting furniture, furnishings and more generally any indoor or outdoor surface. More specifically, the invention refers to a process for obtaining a yarn to be used namely for producing a 5-finger dust-collecting glove. The invention also extends to the yarn thus obtained and to dust-collecting textile products produced with the yarn.
  • This productive option which is the one of interest as far as the present description is concerned, essentially has the advantage of allowing the textile product to be reused over long periods of time, even after numerous washes. Moreover, the fact that no chemical products are used makes the product more environmentally friendly and without contraindications with regard to the tolerability of the product for the user. However, it is difficult to match, with a purely mechanical solution, the dust-collecting capabilities obtained via chemical treatments or the like.
  • the product can advantageously take a substantially mitt-shaped configuration, so as to make cleaning operations more convenient and effective.
  • the actual shape of a five-fingered glove would be particularly advantageous, both to ensure a closer fit on the hand and for a more precise and more controllable dusting action (a single finger being able to be used to reach holes, gaps, cracks or any other motion-hampering areas).
  • this path has not been followed successfully until now.
  • FIG. 1 represents a portion of a composite yarn according to the invention
  • FIG. 2 schematically shows a reel of yarn made in a step of the process according to the invention
  • FIG. 3 illustrates a further, subsequent step of the process according to the invention
  • FIG. 4 shows a perspective view of a dust-collecting five-fingered glove obtained according to the invention.
  • FIG. 5 symbolically represents, in cross section, a portion of knitted fabric obtained according to the invention.
  • a multifilament texturized synthetic yarn available on the market, preferably a non-interlaced parallel assembled polyamide, polyester or polypropylene yarn, even more preferably count 78 dtex with 136 overall micro-filaments.
  • a fabric made with a yarn of this type although being soft and velvety as an effect of the generically voluminous structure of the yarn, would have a reduced capability to trap the dust since the filaments, arranged along the axis of the yarn, would clearly be tangential with respect to the surface to be cleaned.
  • said yarn is used for the formation of pile, extending radially from a sewing core, in turn made through a synthetic yarn, typically a parallel multifilament polyamide, polyester or polypropylene yarn. More specifically, the pile yarn is sewn along the core and concurrently cut so as to obtain a thick succession of radial “whiskers”, each clearly consisting of a bundle of micro-filaments.
  • This step can be carried out by means of known machinery for producing cut and sewn fancy yarns, such as an apparatus with needle spindles (in practice, small adapted circular knitting machines with a sewing needle and a cutting needle), e.g. the model LEGAFIL FT240 produced by the Italian company PAFASYSTEM S.r.l. in Montale (Pistoia).
  • the composite yarn resulting from such an operation thus has a core 1 from which there extends radially, with continuity, a pile 2 of significant length (from about 3 mm to about 10 mm) as well as density along the axis of the core.
  • An optimal effect is obtained by distributing the effect yarn with the linear density of six double whiskers per centimetre. For every centimetre of yarn there will therefore be something like 1632 micro-filaments (136 ⁇ 6 ⁇ 2), projecting with continuity from opposite sides of the core 1 .
  • the composite fancy yarn thus obtained has a double advantageous effect.
  • the composite yarn is used for making a five-fingered glove 3 ( FIG. 4 ) by means of a suitable glove-making machine (as clarified shortly hereafter)
  • a straightforward calculation leads to the approximate number of over 14 million micro-filaments per glove.
  • the filaments that form the pile 2 are arranged so as to be at an angle to a surface S to be dusted, so as to be able to remove and trap the dust as effectively as possible.
  • the invention provides for two further, important productive steps, described hereafter.
  • a first of these steps is related with the steaming treatment, necessary for stabilizing the yarn before weaving or knitting.
  • the steaming treatment necessary for stabilizing the yarn before weaving or knitting.
  • a reel 4 with a quill 5 shall preferably have a D/H ratio of between about 1.5 and 4.5, and even more preferably between 2.5 and 4.5.
  • the reel is characterized by a high surface-volume ratio, thus promoting the penetration of steam into the material, at the same time with a strong mechanical compression effect of the fibre, to prevent the possible contraction of the pile.
  • the reels are protected inside containers, for example open-top boxes covered with sheets of plastic material, to minimise the risk that the yarn might absorb the dust of the surrounding environment already in this step, getting dirty and taking an unpleasant dark colour: obviously, in this type of product a clear colouration is an extremely important feature, since it allows the user to see right away the dirt that has been removed.
  • a further step refers to a step after steaming, and immediately before the entry of the yarn, unwound from the reel, into the weaving or knitting machinery, in particular a glove knitting machine.
  • the yarn is unwound from the reel, the filaments that form the pile 2 are inclined towards the core 1 , due to the radial compression previously undergone in the formation of the same reel, with a consequent reduction in volume of the yarn.
  • the yarn is thus passed through a fixed ring 6 for redirecting the filaments, with the same filaments pointing towards the direction of axial advance.
  • the diameter of the ring 6 is such as to engage with the pile and, thanks to the abutment action thus realized, to cause it to rotate backwards until it is taken back into a position substantially perpendicular to the core 1 of the yarn.
  • the pile 2 thus once again has the maximum opening when the yarn is fed to the machine, and this will ensure that the voluminosity of the yarn can be maintained in the finished product.
  • the firmness with which the pile 2 is fixed to the core 1 ensures the stability of the yarn during the weaving or knitting step. This, as well as avoiding malfunctions and problems with the machine due to the dispersion of fragments of thread, ensures that the dust-collecting product obtained is able to ensure the maximum cleaning effectiveness, even after multiple washes.
  • the objective of obtaining a dust-collecting textile product that, without making use of additives or chemical treatments, has a very strong capability to trap dust, a capability that remains as such use after use, for a long time, is thus achieved.
  • the invention can advantageously be exploited to make a simple dust-collecting cloth, it shall clearly have a particularly advantageous exploitation in making a dust-collecting five-fingered glove.
  • the special qualities of the textile material shall thus be further enhanced by a configuration that makes cleaning easier, quicker, more precise and more effective.
