Definitions

  • the invention relates to the technical sector of knitting on rectilinear loom, for making clothes, of the pullover type and others.
  • the garment and more generally the mesh knitted can be subjected to additional treatments, to give it a specific visual appearance.
  • the mesh can be scraped to obtain a fabric with a velvety appearance.
  • the problem that we propose to solve the invention is to produce an article which is waterproof, anti-stain, while facilitating the circulation of air.
  • the fluorinated resin of TEFLON type is applied to the scarf by subjecting the knitted mesh in a bath of 50 g / l of oleophobol-S and 20 g / l of alcohol isopropyl, the pH adjustment of the bath being brought to 5 with 0.5 g acetic acid.
  • the take-up rate is set at around 80%.
  • Another problem which the invention proposes to solve is to submit the article obtained according to the process of the invention to one or more operations capable of giving it the appearance of a velvety fabric.
  • the fibers of the mesh to an elongation and de-stemming operation, then to a velvety and shaving operation.
  • Figures 1, 2, 3 and 4 are views of a purely character schematic of the treatment method according to the invention.
  • the treatment method according to the invention intervenes after knitting the mesh on a rectilinear loom.
  • the knitted mesh (M) is washed, in particular on an OVER-FLOW type machine. This washing is carried out in the middle alkaline with dispersing detergents to remove mesh, oils and other impurities resulting, for example, from the working of needles and needle beds.
  • the mesh is then rinsed and subjected to a treatment of the type ERONIAL, consisting of an electrolyte bath to facilitate attachment of the fluorinated resin on the knitted mesh, as will be indicated below from the description.
  • This eronal treatment makes it possible to obtain charges negative on the surface of the knitted mesh, thereby attracting positive charges presented by the fluorinated resin.
  • the knitted mesh thus washed, rinsed and treated, is then subjected to a wringing operation, using a wringer of all known and appropriate type.
  • the knitted mesh thus set is then subjected to a drying operation using a relaxing mat (T) ( Figure 3).
  • T a relaxing mat
  • This drying takes place at a temperature of around 145 ° C and at a speed about 10 m / min. Then just apply the fluoride resin in the conditions indicated below.
  • This resin is applied to the scarf, subjecting the knitted mesh in a bath of 50g / l of oleophobol-s and 20g / l of alcohol isopropyl.
  • the pH of the resin bath is adjusted to 5 with 0.5 g of acid acetic.
  • the take-up rate is set at around 80% by means of example, of two pressure rollers (P) (figure 4).
  • the take-up rate is the ratio of difference between the wet mass and the dry mass, on the wet mass. In other words, for an 80% take-up rate, 800 g of bath are taken resin for 1kg of fabric.
  • the fibers of the mesh thus treated can be subjected to an elongation and riddling operation, then a velvety and shaving operation.
  • the whole knitted and treated mesh according to the characteristics of the invention can be subjected to any of the characteristic steps, such as defined in patent application WO 9418368 of which the applicant for the present also holds.
