Definitions
- the present application relates to materials for thermal and sound insulation constituted by moiré a web of chlorovinyl textiles.
- chlorovinyl textiles or chlorofibres
- They are obtained by dry or wet spinning of solutions in a solvent or solvent mixture or extrusion of molten breakage of polymer, copolymer or mixture of polymers based on vinyl chloride optionally superchlorinated.
- chlorofibers in the form of yarns of fibers, filaments, fibers have been used for many textile applications in furnishing clothing, technical applications, where their numerous: characteristics of insensitivity to water, chemicals, exposure to bad weather, cold, fire resistance, decay, rodents, are appreciated.
- Materials for chlorofibers insulation are known, such as those made from drawn, mechanically crimped fibers, used as upholstery in clothing and furniture.
- a standard presentation textile is used which has undergone, after spinning, a drawing operation to give it solidity, then a mechanical crimping operation allowing it to be worked on downstream processing machines.
- the materials for insulation must have a certain number of characteristics, thus in the French application published under the number FR-A-2 173 324, a construction material based on ribbons obtained from sheets of material is described. plastic, this material has coefficients of heat conductivity of the order of 0.04 kcal / mh degree in the form of a plate 65 mm thick and 75 kg / m 3 density, it is also indicated, without specification, however, that this material has a certain degree of soundproofing.
- the present application relates to a material for chlorofiber insulation produced in a simple, economical manner and allowing thermal and sound insulation.
- the present invention relates more particularly to a material for thermal and sound insulation in chlorovinyl filaments or fibers, characterized in that it is in the form of at least one ply made of non-stretched chlorovinyl crimped fabric.
- This material has a thermal conductivity measured at 25 ° and 65% relative humidity of less than 0.04 kilocalorie per meter, per square meter, per hour and per degree C and an alpha sabine absorption coefficient in a reverberation room for frequencies between 400 and 3200 hertz, greater than 0.45 for an average thickness of 4 cm and greater than 0.65 for an average thickness of 8 cm, the density of the sheet being between 15 and 50 kg / m 3.
- the present invention also relates to a process for obtaining a web based on chlorovinyl textile used for the manufacture of a material for thermal or sound insulation which consists in passing through a texturing nozzle supplied with a fluid hot a cable of unstretched chlorovinyl filaments and optionally cutting the crimped filaments obtained into fibers, passing them through a carding device and fixing the sheet in a manner known per se.
- chlorovinyl textile is meant in the present application continuous filaments or fibers based on atactic polyvinyl chloride.
- the pneumatic texturing treatment is generally carried out with steam, preferably according to methods and with devices such as those which are the subject of French documents FR-A-1 289 491 and its additions and the French document FR-A-2 052 161 by the plaintiff.
- the chlorovinyl textiles are treated in the form of continuous filament cables, the nozzles of the devices which are the subject of above-referenced patents being of round or rectangular section. Depending on the width of the nozzle, if it is a rectangular section nozzle, the crimped ply obtained can be used as it is, or enlarged.
- the thermal and sound insulation properties of these sheets are superior to those of glass wool sheets usually used for such applications, thus under equal conditions the glass wool sheets have a thermal conductivity of 1 '' of 0.041 K cal m / m 2 h ° C to 24 ° C, while the chlorofibers of the applicant has a thermal conductivity between 0.030 and 0.038, preferably between 0.033 and 0.036, for a respective density of 16 kg / m 3 for glass wool and 20 to 40 kg / m 3 for chlorofibres.
- the plies which are particularly suitable are those whose apline sabine coefficient is greater than 0.75, which corresponds to plies of average thickness 8 cm and density 40 kg / m 3 .
- the plies thus obtained used as such or linked by binder, needling, resin, high frequency, partial melting, are used for thermal and / or phonic insulation in building applications, in bodywork, in clothing, etc. , alone or in combination with other flexible materials such as aluminized plastic files for example.
- a cable is textured in unstretched pure polyvinyl chloride filaments of 6,600 dtex / 900 strands, after treatment the cable's title is 10 100 dtex: texturing condition: vapor pressure 3.6 kg / cm 2 , cable feed speed: 200 m / min.
- This cable is transformed by cutting into fibers 60 mm long which are then carded.
- Two types of plies are produced, one of density 20 kg / m 3 , the other of 40 kg / m 3 , the thermal conductivity measured according to standard ASTM D 2326-70 is respectively 0.0367 Kcal m / m 2 h ° C at 24 ° C and 0.033 Kcal m / m 2 h ° C, while a sheet of glass wool of common density 16 kg / m 3 has a conductivity of 0.041.
- the alpha Sabine coefficient is determined in a reverberation room according to the prescriptions of the ISO & 354 recommendation and the NF S 31 003 standard.
- the measurements were carried out on 12 m 2 of tablecloth directly placed on the floor of the room, in the center, so as to provide a rectangle of 4 x 3 m.
- a pink sound filtered by a third octave band was used for both transmission and reception.
- the measurements were taken at four points in the reverberation room, chosen so that the microphones are at least 1.5 m from any reflecting part and 1.6 m from the ground.
- the reverberation times, average T o before introduction and average T after introduction of the material into the room, given in the tables, are the arithmetic means of 4 N measurements made for each band of one third of an octave (N is the number of measurements at each point).
- the Sabine alpha sound absorption coefficients given in the tables were calculated from mean T o and mean T.
