Definitions

  • ABSTRACT Object of the invention is a process for preparing a voluminous filament yarn with several loose filament ends sticking out by means of false twist texturization, optionally combined with a drawing process including the use of filaments having-at least partially-a flex abrasion resistance of less than abt. 1500 revolutions, said filament yarns being fed into known false twist texturizing devices and texturized therein, whereby the filaments having flex abrasion resistance values ofless than abt.
  • German Offenlegungsschrift l 660 606 describes a process for preparing such fluffy yarns, which me-- chanically rips and unravels the surface of a drawn filament yarn by rotatingbrushes. But this process is limited to foamed thermoplastic polymers and, obviously, it is applicable to coarse yarns only.
  • British Patent 971 573 claims a similar process, wherein two yarns of different elongation-at break are jointly submitted to a simultaneous stretching and texturizing treatment, and whereby the drawing proportion must be set in such a manner that the breaking filaments are those of the yarn having the lower elongation at break.
  • this process results in a fluffy yarn with several loose filament ends sticking out, it is, however, still ridden by a series of disadvantages. Since the effect looked for can be attained only by elongation, a portion of the filaments up to their breaking point, the yarn tension within the texturizing area cannot be chosen according to the optimal crimping properties. The yarn tension is predetermined already by the requirement of breaking one of the components.
  • an irregular adsorption of dyestuff is the unavoidable consequence of an irregular stretching treatment, so that the woven or knitted fabrics made of these yarns show an uneven coloration.
  • the filament yarns with several loose filament ends prepared as per British Patent 97] 573 show a strong tendency to pilling, such as itis known from spun fiber yarns made of synthetic highpolymers.
  • the object of the present invention to develop an operationally safe process for preparing voluminous filament yarns with several loose filament ends sticking out, whereby the filaments of the yarns display uniform characteristics all over their length and whereby the crimping properties may be freely set depending on the application field of the yarn.
  • the thus prepared fluffy yarns should also be usable for the formation of fabrics excelling in their extremely low tendencyto pilling.
  • the flex abrasion resistance influences the number of the loose filament ends sticking out which are produced in course of the process as per the invention, whereby the filament having the lower flex abrasion resistance does break easier while being exposed to the transversal stress of the texturizing area.
  • the number of the loose filament ends may also be influenced by setting the portion of filaments with a lower flex abrasion resistance used in the total filamentyarn.
  • the tendency to pilling of the woven and knitted fabrics is also decreasing substantially; however, as the term flex abrasion" already implies, it is not normally possible to produce or to use practically useful filament yarns having a flex abrasion resistance of e.g. Zero. But is is possible to use filaments having a flex abrasion resistance of eg as little at 5 revol. in cases, where especially strict requirements are set up concerning the lack of tendency to pilling of certain or knitted fabrics.
  • Threads of linear polymers which may partially be treated in a permanently cross-linked fashion can as well have a reduced flex abrasion resistance. Therefore, same are also well suitable for being processed according to the invention, within the said ranges of flex abrasion resistancevalues.
  • all of the filaments of the filament yarn may have the lower flex abrasion resistance of less than 1,500 revol. looked for, so that they may yield filament ends or only a portion of the filaments does possess these properties, while the rest shows a high flex abrasion resistance so that it does not break while being exposed to the transversal stress in the texturization area.
  • the filaments have to be interlaced slightly tighter for attaining a sufficient strength of the yarn, whilst in the latter case the continuous filaments guarantee anyway a sufficient strength of the yarn.
  • Filament yarns composed in the proportion of 7:3 to 3:7 of filaments having a lower flex abrasion resistance (less than 1,500 revol.) blended with filaments having a flex abrasion resistance of 1,500 and higher (e.g. 3,000 revol.), formed woven and knitted fabrics which excelled in a particularly attractive appearance and remarkable wear. It is also possible to choose freely depending on the specific application field the titer and the profile of the filaments, as well as the number of the filaments, which means the total titer of the filament yarn.
  • the titer will remain within the range of from 1 to 15 dtex per filament and below 300 dtex for the yarn, as it is usual for textile application purposes, but it may as well be set at a higher level for special purposes such as decorative fabrics.
  • the upper limit is, at most, given by the texturization process. ln case that different filaments are worked up into one yarn, their titers and cross sections may differ as well, of course.
  • the filaments are also made of different raw materials, their various characteristic may well be utilized for further effects, such as different shrinkage or bicomponeat-threads may result in additional bulk effects, different adsorption of dyestuffs may lead to mixture yarn or coloured twist yarn effects or the use of flame-proof or flame-retarding yarn components may produce filament yarns of ameliorated flame resistance.
  • a preferred embodiment of the invention are voluminous filament yarns of component blends. which show different individual titers and the loose filament ends of which are formed by the yarn component having the lowest individual titer.
  • both of the two kinds of filaments may be spun by means of one same spinning nozzle, or of two adjacent spinning nozzles, such as described by British Patent 1208 801. But it is also possible to ply the various types of filaments while passing the stretching area. A better blending may, in any case, be encouraged by interlacing or applying an electrostatic charge.
  • the usually preferred devices are false twist spindles, since the turning around on the spindle favors even better the formation of filament ends than the torsion stress alone occuring during the frictional texturization.
  • the number of the loose filament ends is also influenced, for instance, by the texturization parameters temperature, yarn tension upstream and downstream the spindle, coating product, number of spindle revolutions, travel speed of the yarn as well as by the shape and surface characteristics of the spindle. 1
  • a preferred embodiment of the invention for producing filament yarns consisting of polyester filaments is the simultaneously executed drawing and texturizing process of undrawn spinning materials (threads), whereby especially the use of undrawn, pre-orientated polyester filaments according to the U.S. Patent application Ser. No. 338,312 may give optimal texturization results.
  • the drawing proportion that is the proportion of the initial speed to the final speed of the yarns in the false twist texturization apparatus has to be chosen so as to draw all the filaments completely.
  • efforts have to be made by the choice of different pre-orientations to adapt, as far as possible, the drawing proportions of all filaments to each other. This is the only possibility that guarantees the all-over uniform drawing of all the filaments over 5. their total length, and thus to guarantee an even adsorptionof dyestuff.
  • the process according to the invention does not insist in imparting to the fed-in spinning yarns a flex abrasion resistance of less than e.g. 1,500 revol. already be fore the combined drawing and texturization, in case that undrawn or partially drawn filament yarns are utilized.
  • the reduction according tothe invention of the flex abrasion resistance of at least one titer of the filaments cannot be dispensed with at the moment of the yarn reaching the twister of the used false twist device.
  • the broken fil ament ends are partially still sticking out far of the filament yarn, so that they have to be interlaced at least temporarily before being submitted to further treatment.
  • a preferred method for ameliorating the filament bonding is to interlace the threads immediately after their having left the false twist texturization.
  • Theinterlacing by gas-blasting replaces generally more and more the twist process when preparing synthetic threads, since this gas-blasting may take place at high turnover speeds and continuously following other processing stages.
  • U.S. Pat. No. 2985 995 e.g. describes interlacing devices.
  • the open structure of the voluminous filament yarns may well be entirely preserved, if interlacing of the filament ends may be produced by application of a size which can be washed out again after weaving or knitting.
  • the voluminous filament yarns with loose filament ends sticking out according to the process of the invention show their superiority in course of their further treatment especially by the high degree of levelness of all their textile technological properties-all over the length of the yarn.
  • These yarns display a distinctly higher volume compared to the usual texturized filamentyarns having also a considerably higher covering power. Therefore, it is possible to produce the same individual impression of a specific material already at a noticeably reduced weight per square meter.
  • the most remarkable quality of the fabrics formed by the filament yarns of the invention is their extremely low tendency to pilling.
  • the flex abrasion resistance was determined, as said before, by means of a flex abrasion device, whereby the filaments to be examined are loaded with 0,45 g/dtex, the diameter of the wire being 0,02 mm up to 6,7 dtex 0,04 mm up to 13 dtex and 0,05 mm for even higer ti ters, flexing takes place at an angle of 1 10 at a speed of 126 revol/min.
  • EXAMPLE 1 a 67 f40 was prepared similar to example 1 of German Auslegeschrift l 720 647, whereby the 2,4 g of zinc acetate were replaced by 3,1 g of manganese acetate and whereby the quantity of the trimethoxysilanethanephosphonic acid-diethylester was increased from 48 g to 72 g.
  • the two polymer materials were spun in one spinning nozzle according to U.S. Pat. No. 2 398 729 at a temperature of 290C and the spinning threads'fed in and taken up at a speed of 1400 m/min.
  • the relative viscosity of the spinning threads amounted to 1,80 to 1,56.
  • the elongation at break of the filaments amounted to 310 percent for the coarse titers and 375 percent for the finetiter filaments at room temperature, the double refractions of the filaments amounted to 9,3 or 6,6- 10*.
  • the blended yarn obtained was submitted to a simultane ous draw-texturization in a false twist texturizing apparatus with false twist spindle having a'sapphire center pin.
  • the feed-in speed was 57 m/min the output speed was 166 m/min corresponding to a stretchproportion of 122,90.
  • the yarn was first directed in the texturization device over a contact heater 1 m long, having a surfacial temperature of 190C, the distance between the contact heater and the spindle was 15 cm.
  • a false twist was imparted to the filament yarn of 2,700 revol/m.
  • the filament yarn was interlaced in a gas jet after having left the texturizing device, and then rolled up.
  • the obtained voluminous filament yarn showed an average of two loose filament ends per cm of yarn length. This fact allows to estimate an average staple length of abt. 40 cm, considering the 40 individual filaments of the yarn component 67 f 40.
  • the broken filament ends showed a flex abrasion resistance of 350 revol., whilst the filaments of the other yarn component (67 f 12) showed a flex abrasion resistance of 3,630 revol (in each case is given the average out of 25 measurings).
  • EXAMPLE 2 A filament yarn of the total titer of dtex 135 f52 according to example 1 had been worked up to a fabric with linen weave in warp and weft, the weight per sq.m was 106 g. The fabric was finished as usual, i.e. washed, dried, dyed minutes at C) and set (156) and then submitted in this condition to a pilling test by the Random Tumble Pillinger Tester.
  • FIG. 1, line A represents the values measured.
  • comparative test C under the chosen test conditions shows a strong tendency to pilling, which climbs fast to value 7 (heavily pilled, shape of the pill mostly ripe) during the test and then remains on this level.
  • value 7 herein.
  • a fabric made of low-pilling polyethyleneterephthalate-fiber yarn shows after having passed an initial maximum stable values of the test grade 1,
  • Double-sided circular knit goods having a weight p/sq.m of abt. 173 g/sq.m each have also been produced of the filament yarns of example 1 as well as ofthe fiber yarn specified above, and submitted to corresponding pilling tests.
  • the pilling curves obtained for these knit goods were exactly of the same direction as the line of FIG. 1.
  • the fabrics produced of the voluminous filament yarns according to the invention showed remarkable differences concerning covering power, volume and purity of the appearance compared to those made of fiber yarns, at the same weight per square meter. All the criterions could be much better evaluated via the to the invention.
  • EXAMPLE 3 The undrawn blended filament yarn according to example l was submitted to a so-.called sequence texturization process.
  • the drawing of the yarn occurs between two feed-in devices at speeds of 48 and 166 m/min. over a pin heated to 90C..
  • the yarn, immediately after the drawingprocess still entirely free of loose or broken ends, was then directly fed into a continuously working false twist apparatus, the same embodiment as specified in expl. l.
  • the yarn was charged with a false twist of 2,700 r/m and after having left the texturization device the yarn is treated with a sizing product of acrylic acid ethylester, acrylic acid amide and acrylic acid sodium salt for amelioration of the filament bonding.
  • the size coating amounted to abt. 10wt/.
  • the obtained voluminous filament yarn having several loose filament ends sticking outshowed abt. 2 filament ends per cm of yarn length.
  • EXAMPLE 4 According to a further operational variation of the invention the filament yarn had been produced in such a way, that the two blended yarn components were spun separately, plyed in a draw'twister and then texturized.
  • the spun material was polyethyleneterephthalate, as described in example 1, at a temperature of 290C.
  • the yarn component for producing dtex 67f 12 was rolled up at a melt output of 35,5 g/min at a speed of 2 400 m/min., whilst the yarn component for dtex 67 f 40 was rolled up at a melt output of 32,5 g/min at a speed of 2,200 m/min.
