Definitions

  • the present invention relates to a process for forming a nonwoven web of synthetic filaments in which the synthetic filaments are extruded, stretched, cooled, and projected onto a moving plastic canvas (SPUNBONDED and MELTBLOWN processes).
  • 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 formation canvas which advances at constant speed.
  • a suction under the fabric eliminates the air and presses the veil against the fabric.
  • plastic forming fabrics which by their flexibility allow an easy installation and are easily guided, but it is not possible to clean them and their lifespan is therefore relatively short.
  • 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 a hot fluid (steam or hot air) at high speed, the temperature of which is between t2 and t Orchestrae and preferably chosen to be 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 extrusion dies 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 coming 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 temperature of the fabric
  • t2 that of the filaments.
  • t1 is at least 80 ° C higher than the temperature t2.
  • the fabrics 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 of warp and weft monofilaments in the form of single or multi-layer fabric. They are thermally stabilized according to the conditions of use.
  • 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, two series of loops of different lengths can advantageously be provided at each end as described in French patent no. 72 27 942.
