Definitions

  • the present invention relates to the field of the production of nonwoven webs or bands, of continuous filaments obtained by spinning polymers in the molten state, and relates to a process for manufacturing a nonwoven web constituted continuous filaments linked together, as well as a sheet thus obtained.
  • These current bonding methods consist in treating by jets of fluids, in particular by high-pressure water jet, the nonwovens obtained by techniques such as the wet process or the dry process (by mechanical or pneumatic carding of fibers of 20 up to 80 mm in length).
  • the wet process uses short, flat fibers, rarely exceeding 20 mm in length.
  • the dry route uses generally crimped fibers, which greatly facilitates the production of unitary sails, the length of which can be up to 80 mm.
  • Nonwoven webs most often use mixtures of synthetic fibers, with the possible addition of artificial or natural fibers.
  • Natural or artificial fibers often of cellulose origin, allow, by their presence, a better yield of binding by jets of water under pressure because of their sensitivity to this element.
  • the great mobility of the cut fibers allows a rearrangement of the structure by sliding all or part of the fibers in the direction of the lines of force exerted perpendicular to the plane of the sheet.
  • the object of the present invention is in particular to overcome these drawbacks.
  • It relates, in fact, to a process for manufacturing a nonwoven web made up of continuous filaments bonded together, characterized in that it consists in producing a nonwoven web from biconstituated filaments having a crimping, then subjecting said ply to jets of fluid under high pressure, the mechanical action of which causes entanglement and interlacing of the crimped filaments constituting said ply.
  • the manufacturing process consists, first of all, in producing a nonwoven web from biconstituated filaments having a crimp, then in subjecting said web to jets of fluid under high pressure, of which the 'mechanical action causes entanglement and interlacing of the crimped filaments constituting said sheet.
  • the maximum deformation of a filamentary element composed of a crimped filament is significantly greater than that of a filamentary element composed of a straight, flat or right ( Figure 1), for elements with identical distances between their ends.
  • the force required for the displacement or deformation of such a crimped filament is less than that required for a straight filament, for a similar result.
  • the biconstituted and crimped filaments, constituting the nonwoven web have a bimetal structure comprising two elementary filament components consisting of two different polymers.
  • nonwoven web composed of curly continuous filaments, with a bimetal structure can in particular be carried out according to the method described in French deposit n ° 83 08770, leading to spontaneous, intense and stable crimping due to the behavior asymmetric filaments during air cooling or during drawing.
  • Biconstituated filaments comprising two filamentary components side by side, are advantageously composed of two different polymers, in the form in particular of a combination, on the one hand, of a polyamide chosen from the group formed by polyamide 66, the polyamide 6 and polyamide 11 and, on the other hand, a polyester chosen from the group formed by polyethylene terephthalate, polybutylene terephthalate and copolyester.
  • polyester-polypropylene, polyamide-polypropylene couples, couples of two different types of polyamides or different polyester couples, such as polyethylene terephthalate and polybutylene terephthalate, are also very suitable for obtaining bimetallic structures leading to a spontaneous crimp.
  • the proportions of the two polymers, constituting the bimetallic strip can vary in notable proportions from 95/5 to 5/95.
  • the relative proportions of one and the other of the constituents also influence the quality and intensity of the crimp.
  • the adjustment of this proportion of the one and the other constituent is one of the means of regulating the crimping of the filaments.
  • filaments can be obtained by various known spinning / extrusion methods and present, in addition to a circular section, various sections such as, for example, trilobed, quadrangular sections, or else in the form of crescents or quarters.
  • the latter can, if necessary, be increased by additional chemical treatments, such as those described in the aforementioned deposit or physical treatments such as heat treatment causing differential shrinkage on each of the polymers.
  • the method can advantageously consist, in the case of elementary filamentary components made of incompatible polymers, in subjecting, via the jets of fluid, the filaments of the nonwoven woven to a mechanical action, the intensity of which is such that said filaments are dissociated into their elementary filament components, the latter then being interlaced and entangled under the effect of said jets of fluid.
  • the complete separation or dissociation of said filament is effective under the action of jets of water under high pressure and thus allows d '' obtain, for example, from a biconstituted filament of 2 dtex, two 1 dtex filaments separated.
  • This lowering of the titer of the filaments also contributes to obtaining a better reaction of the fibrous network to the mechanical action of the water jets improving the entanglement.
  • the titer of the biconstituent filaments used is less than 4 dtex, said filaments having a crimp frequency of 3 to 30 crimps per centimeter, preferably 8 to 20 crimps per centimeter and a crimp rate of 50 to 400%.
  • crimp designates in this specification the waviness in space of a wire or a filament and can be defined numerically by the values of the crimp frequency, designating the number of crimps per unit length of wire or of filament, and the crimp rate indicating, in percentage, the difference between the straightened length and the crimped length of the wire or filament compared to the straightened length of the latter or of the latter.
  • the nonwoven web produced by means of biconstituted and crimped filaments has a weight of 10 to 400 g / m2, preferably from 20 to 200 g / m2.
  • the fluid jets consist of water jets applied under a pressure of 50 to 300 x 105 Pa, preferably from 100 x 105 to 250 x 105 Pa, said jets being advantageously applied to the two sides of the nonwoven web.
  • the nozzles for generating the jets of fluid may advantageously have a diameter of ejection orifices comprised between 100 ⁇ m and 250 ⁇ m, said nozzles being grouped on bars, arranged in one or more rows, with a spacing between orifices of ejection preferably between 0.2 and 1.2 mm.
  • the fabrics supporting the nonwoven, during the binding treatment are made of metallic or synthetic filaments and their type of structure and the tightening of the mesh conditions the appearance of the nonwoven after the treatment, as well as the dimensions and the nozzle spacing.
  • the fabrics supporting the nonwoven web during the application of the fluid jets consist of tight metallic fabrics of 80 to 120 mesh.
  • the working speed possibilities depend on the titer of the filaments, their Young's modulus, their sensitivity to water, the weight / m2 of the nonwoven, of course the energy available per unit area, and finally the desired binding effect. They can be located between 10 and 100 m / min or even more for very light sheets.
  • a subject of the invention is also a nonwoven web, obtained by the method described above, and composed either of biconstitued continuous filaments comprising a crimp, said web having a linked structure resulting from entanglement and an intense intertwining of said filaments, that is to say of continuous curled tangled and interlaced filaments, consisting of two different materials and obtained by dissociation of biconstitued continuous filaments with bimetal structure.
  • the plies thus treated have, on the one hand, the properties of nonwovens of continuous filaments, such as very high levels of resistance to tearing, tearing and puncturing, but also, on the other hand, the flexibility , the drape, opacity and the so-called "lintfree” property, that is to say having no free fibers or fibrils, which represents a considerable advantage in medical and surgical applications such as dressings, operating field, medical gowns or the like, and provides high resistance to rubbing and household washing. These properties can be further improved by conventional finishing treatments in the textile industry.
  • textile finishing treatments such as dyeing, printing by transfer methods, pigmentary or fixed-washed printing, scraping or emery-treating treatments or the like may advantageously be carried out according to the applications. .
  • the applications of tablecloths thus obtained can also extend to other textile applications such as furniture (drapes, wall coverings, clothing in the traditional flannelized or felted aspects, seat or bedding coverings, blankets, etc ...), coating supports (shoes, leather goods, luggage, automotive interior trim, etc %) or synthetic suede or coated leathers obtained by impregnating flexible binders or for example polyurethanes coagulated.
  • furniture drapes, wall coverings, clothing in the traditional flannelized or felted aspects, seat or bedding coverings, blankets, etc
  • coating supports shoes, leather goods, luggage, automotive interior trim, etc
  • synthetic suede or coated leathers obtained by impregnating flexible binders or for example polyurethanes coagulated.
  • the 110 g / m2 sheet thus obtained consisting of bicomponent filaments and whose spontaneous crimp, revealed on receipt on the receiving apron, is 16 crimps / cm, is then transported at a speed of 12 m / minute to a water jet binding device equipped with a 100 mesh metallic transport fabric with an opening of 25%.
  • the tying device makes it possible to successively treat the nonwoven on one face, then the other, using two sets of four rows (bars) of jets spaced apart from each other by 0.6 mm.
  • the nozzle orifices have a diameter of 100 ⁇ and the pressures of the water jets of each of the rows are successively 160 - 220 - 140 - 140 x 105 Pa on the first set and on one face, the same for the second set located on the other side of the tablecloth.
  • the tablecloth after wringing, is dried on a through air drum, at a temperature of 160 ° C.
  • the tablecloth obtained has a very soft touch and is very flexible.
  • the breaking load as well as the energy of rupture of the sheet, measured according to standard AFNOR GO7OO1, the resistance to tear initiated, measured according to standard AFNOR GO7055 and the resistance to bursting, according to standard AFNOR GO7112 are with a very high level; flexural rigidity is achieved in accordance with ISO / TC.94 / SC 1139 F 3/70.
  • the deformation under load is also very limited, which perfectly demonstrates the very good level of bonding.
  • a nonwoven web made up of continuous and crimped filaments with a bimetal structure of polyamide 6.6 / polyethylene terephthalate (50/50) of 1.5 dtex bonded by jets of water under pressure according to the method described above, and, on the other hand, a nonwoven web (B) made up of monolame filaments, continuous and uncrimped, of 1.5 dtex, and polyester polyethylene terephthalate compounds.
