Definitions

  • the individual gas streams intercepting and directing their respective filaments outwardly from a spinning nozzle toward a collecting surface, collecting the filaments onto a moving surface as a web of intermingled substantially non-shrinkable polyamide filaments and shrinkable polyester filaments, and subsequently shrinking the polyester filaments in the web.
  • This invention relates to a process or method of forming non-woven webs, fabrics, sheets, bands or similar textile products of synthetic polymer filaments, and more particularly to the formation of a non-woven, felt-like textile web composed of polyamide and polyester filaments.
  • animal fibers such as wool are capable of being felted to form a non-woven, felt-like web or fleece because these natural fibers have a unique surface structure.
  • Spun fibers of synthetic thermoplastic polymers such as polyamides and polyesters, do not have this property or tendency of felting. It has therefore been extremely diflicult to develop satisfactory techniques for the formation of non-woven webs or textile fabrics from these synthetic fibers.
  • the web can be formed on cards or garnetts or else with the aid of so-called air-lay machines from a mixture of staple fibers containing a certain proportion of shrinkable fibers.
  • the resulting web is then bonded by means of a needle loom in which barbed needles engage individual fibers and draw them through the web, thereby interlocking groups of fibers and providing a mechanical bond.
  • the non-woven web is subjected to a treatment in which the shrinkable fibers contract.
  • the web formation can also be accomplished by depositing or wet-laying relatively short staple fibers from an aqueous dispersion onto a screen, a procedure which corresponds closely to the manufacture of paper.
  • the resulting wetlaid web can then be further processed to achieve the desired fiber shrinkage or contraction as described above or by similar techniques.
  • this wet process is usually considered to be better adapted to the production of hard surfaced paper-like products rather than soft and relatively voluminous felt-like products.
  • One object of the present invention is to provide a new method of producing a non-Woven web of synthetic polymer filaments which does not require any intermediate steps between the spinning of the filaments and formation of the non-woven web and which nevertheless is highly effective in forming a relatively soft, felt-like textile material.
  • Another object of the invention is to provide a process for the production of a non-woven web of polyamide and polyester filaments wherein the extruded or melt spun continuous filaments can be directed at various angles onto a collecting surface, preferably so as to provide a selective orientation of the shrinkable fibers and a corresponding selective contraction in length and width of the web together with a change in the web thickness.
  • Still another object of the invention is to provide a process for the formation of a synthetic polymer non-woven web which does not require the fibrous material to be mechanically worked, as in the usual carding, needle punching or felting methods and which also does not require special bonding agents or other expensive additives.
  • Yet another object is to provide a textile product in the form of a non-woven web of synthetic polymer filaments produced in accordance with the process of the invention.
  • the resulting non-Woven web then contains nonshrinkable polyamide filaments which are tangled or intermeshed with shrinkable polyester filaments, and the latter can then be shrunk in a conventional manner, preferably without any tension or pressure on the web, in order to yield the desired textile product.
  • FIG. 1 is a cross-sectional view of a jacketed nozzle suitable for extruding and directing both the polyamide and polyester filaments onto a collecting surface in forming the non-woven web;
  • FIG. 2 is a schematic perspective view of a web-forming apparatus including a cylindrical collecting surface on which the filaments can be formed into a non-woven web and nozzles corresponding to that shown in FIG. 1;
  • FIG. 3 is a schematic perspective view of a web-forming apparatus which is identical to FIG. 2 except for the placement of the nozzles;
  • FIG. 4 is a schematic perspective view of another webforming apparatus in which the collecting surface is a continuous screen, belt or band on which the filaments are deposited by suitable nozzles.
  • the individual filaments or fibers are produced by means of the jacketed nozzle 1 in which the molten polymer introduced from the threaded conduit 2 is pressed through a tubular channel 3 which issues into the conical extrusion tip 4 provided with a number of orifices or openings 5 through which the molten polymer is extruded in the form of continuous filaments.
  • the lower end of the tube 3 is surrounded by a jacket 6 which is connected to a lateral feed conduit 7 for the introduction of steam or air.
  • a collar or ring 8 is mounted on the tube 3 just above the conical tip 5 at the outlet end of the nozzle, thereby providing a narrow annular gap space 9 spaced radially outwardly from the tube 3 and directly above the cone 4.
  • the end of the jacket 6 is extended downwardly past the orifices 5 a short distance, but preferably not beyond the tip of the cone, so that the high velocity annular gas stream is directed downwardly to intercept and guide the extruded filaments without contact of these filaments with the jacket wall or with each other during this initial extrusion and gas stream guidance near the outlet end of the nozzle.
  • the proposed construction of the nozzle is thus particularly advantageous in that, on the one hand, the separately extruded filaments are not immediately recombined into a single strand or into an overly matted or coarse bundle and, on the other hand, the filaments can be rapidly spun and directed by the gas stream so as to be deposited in tangled form on a moving collecting surface over an adjustable area.
  • the diameter or denier of the filaments can be varied within wide limits by changing the temperature and velocity of the gas as well as the size of the spinning orifices.
  • Especially desirable results are achieved when the filaments are formed into a non-woven web with an individual filament titer in the web itself of about 0.3 to 15 denier. With the nozzle illustrated in FIG. 1, it is thus preferable to employ orifices or nozzle openings with a diameter of about 0.3 to 0.6 millimeter.
  • the polyamide filaments should consist essentially of nylon, i.e. one of the well known fiber-forming polyamides characterized by recurring carbonamide groups (NHCO) separated by an alkylene chain of at least two carbon atoms and especially polyhexamethylene adipamide or polycaprolactam.
  • the polyester is preferably polyethylene terephthalate or modified forms thereof which are capable of exhibiting a relatively high shrinkage capacity.
  • Continuous filaments of the polyester are obtained if the molten polymer is spun into an air stream maintained at a temperature of about 300 C. to 330 C. and having the prescribed gas velocity. At temperatures above 330 C., continuous filaments can still be produced provided that the velocity or flow speed of the air is not too high. The resulting filaments or fibers exhibit an extremely high shrinkage capacity.
  • any other inert gas may be employed as a means of applying the polyester filaments to the non-woven web, the term inert being used herein to denote the fact that the gas is not capable of causing any substantial shrinkage of the filaments in addition to the fact that the gas should have no tendency to deteriorate or impair the polyester filaments by a chemical reaction.
  • the ratio by weight of polyamide: polyester filaments combined in the non-woven web can be varied from about 90:10 to 20:80, preferably about :20 to 60:40.
  • the separately spun polyamide and polyester filaments are collected or gathered together on any suitable moving surface structure, preferably one which has both longitudinal and reciprocal transverse movement with reference to the points at which the filaments are extruded and directed by their respective gas streams toward this surface.
  • any suitable moving surface structure preferably one which has both longitudinal and reciprocal transverse movement with reference to the points at which the filaments are extruded and directed by their respective gas streams toward this surface.
  • the collecting surface on which the filaments can be laid to form an intermingled web there can be used a rotating and axially reciprocating cylinder or drum as shown in FIGS. 2 and 3.
  • the drum 10 with its axial spindle 11 can be mounted in any conventional manner, e.g.
  • the filaments or fibers can be collected in any desired state of disorder or intermingling during formation of the web.
  • a higher circumferential velocity and/or a slower traverse stroke of the drum leads to a selective orientation of the filaments in the longitudinal direction of the web.
  • a substantially fiat collecting surface in the form of an endless or continuous moving belt, band or screen 14 carried by the end rollers 15 and 16, both of which can be rotatably mounted to move the belt in a longitudinal direction as well as being mounted for axial reciprocation to move the belt transversely in a regular pattern.
  • nozzles for each type of filament, either adjacently or successively, so as to more rapidly form the web over a given area of the collecting surface.
  • two or more drums or endless belts can be arranged together with suitably spaced nozzles to achieve a continuous web formation.
  • the thickness of the web as it is formed can be adjusted to any desired extent, and many variations in the combination of the nozzles and collecting surface will be readily apparent to those skilled in this art.
  • mount the nozzles for reciprocating transverse movement with reference to the longitudinal direction of the web as it is formed on the drum or on an, endless belt.
  • the polyamide and polyester can be initially melted and placed under pressure with any suitable extrusion device, e.g. a continuous screw extruder, as employed in a conventional melt spinning apparatus.
  • a suitable extrusion device e.g. a continuous screw extruder
  • the jacketed nozzles provided with a gas inlet are simply substituted in place of the conventional spinning nozzles.
  • the web can be withdrawn and subjected to a shrinking treatment, preferably without placing any tension or pressure on the web.
  • This shrinkage can be accomplished in any conventional manner as known for polyester filamets and fibers, e.g. by subjecting the web to the action of steam at about 100 C. to 120 C.
  • the amount of shrinkage can also be influenced by the choice of fluid shrinking agents other than steam and/ or the conditions under which shrinkage takes place.
  • the shrinkage temperature should fall substantially below the melting point of the filaments, since excellent results are achieved without selectively melting one of the filaments.
  • the extent to which the length and width of the nonwoven web shrinks during the after-treatrnent with steam or a similar shrinking agent can be further influenced by the angle at which the polyester filaments are sprayed or directed at the collecting surface. For example, if both of the spinning nozzles are arranged such that the gas streams carry the filaments radially onto the cylindrical collecting surface as shown in FIG. 2, then the web will exhibit about equal shrinkage in length and width. On the other hand, if the polyamide filaments are directed radially against the drum surface but the polyester filaments fall tangentially thereon as illustrated in FIG. 3, then the web will exhibit a greater shrinkage in the longitudinal direction. As indicated in FIG.
  • the nozzle from which the polyester emerges can also be arranged at various angles with the flat planar collecting surface of the endless belt, i.e. so that the air stream is directed perpendicularly to the moving surface or at an acute angle with reference to the angle formed by a line corresponding to the gas stream and its projection onto the collecting surface.
  • the arcuate or fiat shape of the collecting surface it will be recognized that a greater lateral or transverse orientation of the polyester filaments can be developed by increasing the reciprocal speed of transverse motion of the gas stream with reference to the longitudinal speed of the collecting surface.
  • the degree of shrinkage in the width and length of the web can be readily adjusted by the angle of the nozzles and also by the speed of longitudinal and transverse motion as the web is formed.
  • Example 1 A nylon melt consisting of polycaprolactam heated in a conventional extruder to a temperature of 285 C. is spun through a nozzle with nine openings as shown in FIG. 1. Each opening in the nozzle cone or tip has a diameter of 0.5 mm. Steam is introduced into the jacket portion of the nozzle so as to flow therethrough at a velocity of 70 meters/second and at a temperature of 330 C. The amount of nylon extruded in the form of continuous filaments is about 150 grams/hour.
  • a polyethylene terephthalate melt heated to a temperature of 290 C. is spun through a second nozzle with four openings, each having a diameter of 0.4 mm., into a stream of air having a velocity of 70 meters/second and a temperature of 340 C.
  • About 68 grams/hour of the polyester are extruded in the form of continuous filaments.
  • the two nozzles are arranged over a cylinder or drum collecting device as shown in FIG. 2 such that the nylon and polyethylene terephthalate filaments are directed approximately radially onto the drum surface.
  • the distance of each nozzle from the surface of the drum is 40 cm.
  • the drum has a diameter of 65 cm. and a width of 50 cm. and is rotated at a circumferential viscosity of about 10 meters/ minute.
  • the drum is transversely reciprocated at the rate of 1.5 strokes per revolution of the drum about its axis.
  • the filaments are deposited in a disordered or tangled state to form an even fleece on the drum surface, and the resulting web contains about 30% polyester filaments and 70% polyamide filaments intermingled with each other.
  • the thickness of the web is 1.20 mm.
  • the web is then subjected to a shrinkage treatment while completely free of tension by the application of steam at about C. for one minute. There occurs a very nearly uniform surface shrinkage in both longitudinal and transverse directions of the Web of 25-30%, and the thickness of the Web increases to 3.06 mm.
  • Ratio of polyester polyamide Thickness of the web 1 Surface shrinkage approximately uniform in both length and width.
  • Example 2 The process is repeated under exactly the same conditions as described in Example 1 except that the polyamide filaments are directed radially against the drum surface while the polyester filaments are directed tangentially onto the surface as shown in FIG. 3.
  • an air velocity in the polyester nozzle of 70 meters/second and a ratio of polyester to polyamide of 30:70 there is obtained a non-woven web which has a thickness of 1.35 mm. before shrinkage and 5.76 mm. after shrinkage.
  • the surface shrinkage of the web amounts to 40-45% in the longitudinal direction (corresponding to the circumference of the drum) and 25-30% in the transverse direction (corresponding to the width of the drum).
  • the process of the invention does not require any expensive intermediate steps in the formation of staple fibers or so-called fibrids nor is it necessary to use special bonding agents, adhesives, needle punching, fabric backings or similar means of ensuring a coherent fleece or web.
  • additional techniques can be adopted in combination with the invention in order to obtain special effects or to use the non-woven web of the invention in the fabrication of various textile products, e.g. as linings or interlinings for clothing, blankets, sleeping bags and the like.
  • a process for the production of a non-woven web of synthetic polymer filaments comprising:
  • extruded polyamide and polyester filaments are directed by their respective streams of steam and an inert gas toward a rotating and axially reciprocating cylindrically-shaped collecting surface.
  • extruded polyamide and polyester filaments are directed by their respective streams of steam and an inert gas toward a substantially fiat collecting surface which has both longitudinal and reciprocal transverse movement relative to the points at which said filaments are extruded and directed toward said surface.
  • a process as claimed in claim 1 wherein the weight ratio of polyamidezpolyester is about :20 to 60:40.
  • polyester filaments are shrunk by treating said web with steam at a temperature of about C. to C. while maintaining the web substantially free of compression and tension.
