Definitions

  • the present invention relates to a method for cleaning a nonwoven web for forming synthetic filaments in which the synthetic filaments are extruded, they are stretched, cooled, and projected onto a moving plastic canvas (SPUNBONDED processes and MELTBLOWN).
  • ramps of dies are used placed above a forming fabric.
  • Various polymers polymers (polyester, polyamide, polyolefins, etc.) are hot extruded.
  • the filaments are, using a violent current of air, stretched, cooled and projected onto the circular forming fabric which advances at constant speed.
  • a suction under the fabric eliminates the air and presses the veil against the fabric.
  • a special plastic forming cloth having a melting temperature t1 at least 80 ° C higher than the melting temperature of the filaments t2 constituting the web, which makes it possible to clean the cloth by passing through '' a hot fluid (steam or hot air) at high speed whose temperature is between t2 and t1 and preferably chosen close to
  • the invention also relates to fabrics allowing the application of the method.
  • a closed plastic cloth 1 is provided, mounted around rollers 2. Above the upper horizontal part of the cloth 1, there is a ramp 3 of proud extrusions surrounded by an air jet generator 4. The ramps 3 oriented vertically and over the entire width of the fabric 2 are used for the extrusion of synthetic filaments 5 which are projected by the air from the ramps 3 onto the fabric 1 in continuous movement to form a veil 6.
  • the veil 6 is plated on the fabric 1 by the suction of the air made by a device 7 arranged below the fabric 1.
  • a hot fluid steam or air
  • t1 being the melting point of the fabric and t2 that of the filaments.
  • t2 the material of the fabric 1 so that t1 is at least 80 ° C higher than the temperature t2.
  • the fabric 1 can be cleaned by melting the drops of material stuck in the fabric 1 without the latter being damaged.
  • the fabrics 1 are made up of warp and weft monofilaments in the form of a single or multilayer fabric. They are thermally stabilized according to the conditions of use.
  • the characteristics of the fabrics 1 are chosen (air permeability, weave, surface condition, etc.) as a function of the characteristics of the nonwoven veil to be formed.
  • Their weight can be between 500 to 1500 gr / m2 and their permeability between 4000 to 25000 m3 / m2 / h under differential pressure of 100 Pascals.
  • These fabrics can be circular or with junctions. These can consist of loops at each end of the canvas. In this case, one can advantageously foresee at each end two series of loops of different lengths as described in French patent n ° 7227942.
