Definitions
- the present invention relates to PTT staple fibers [wherein PTT is equal to poly (trimethylene terephthalate)] and a process their manufacture by a two-stage spinning and stretching process.
- Staple fibers made of polyethylene terephthalate and melt spinning lines too their manufacture is known (Fourné, synthetic fibers, Hanser Verlag [1995] pages 460 - 462). Because of the different These processes are not so easy to crystallize transferable to PTT.
- EP 0 547 553 A1 describes the production of monofilaments 20 m / min spinning speed and a production speed of 100 m / min.
- EP 0 754 790 A2 describes the production of textile filaments u. a. made of PTT by means of heating surfaces heated to high temperatures as stretching aids. Concrete embodiments are missing.
- WO 99/11845 A1 describes fibers made from PTT, with birefringence of at least 0.030 is obtained.
- the specified characteristics show low elongation at break of ⁇ 90%, suitable for further processing not allow a sufficiently high draw ratio to staple fibers and are unsuitable.
- WO 99-27168 A1 discloses a high-speed spin-stretching process for the production of PTT filaments that are wound on yarn packages. Leave high throughputs and cable storage for the production of staple fibers do not derive from it.
- CA 86: 122865 for JP 52-08123 A describes the use of one per se desired high draw of 300% in the production of PTT fibers.
- the spinning speed of 360 m / min practiced for this is however so low that the economy of the process in Question is asked.
- CA 86: 122856 to JP52-05320 A describes the spinning of PTT, whereby the stretching ratio practiced to uneconomically low Spinning speeds indicates.
- the object of the present invention is to produce PTT staple fibers To provide, these and those made from them Textiles and home textiles, especially carpets, compared to conventional fibers a high degree of aesthetics and quality of use as well as environmentally friendly coloring properties.
- the Manufacturing these PTT staple fibers should be done in a two step process melt spinning and drawing, which is a higher Has economy than the previously mentioned methods for Continuous filaments.
- this object is achieved by means of PTT staple fibers and a method for producing PTT staple fibers with an intrinsic viscosity of at least 0.70 dl / g according to the Disclosure of claims.
- PTT here is a polyester with at least 90 mol% Understand trimethylene terephthalate units. Suitable as comonomers isophthalic acid, 2,6-naphthalenedicarboxylic acid, ethylene glycol, Diethylene glycol, 1,4-butanediol, 1,4-cyclohexanedimethanol. Prefers is poly (trimethylene terephthalate) homopolymer and is particularly preferred those with a low proportion of during the manufacturing process formed ether groups derived from 1,3-propanediol.
- the intrinsic The viscosity of the PTT staple fibers is in the range from 0.7 to 1.3 dl / g and particularly preferably 0.75 to 1.15 dl / g.
- the starting point is PTT melt, which either directly Polycondensation reactor is removed from the PTT production or is obtained by melting PTT granules.
- the polymer melt can contain common additives such as dyes, matting agents, Stabilizers, antistatic agents, lubricants, branching agents, in quantities contain a total of 0 to 5.0 wt .-% or the additives be added to the melt on its way to the spinnerets. Additives that contain structural characteristics (e.g. Noticeably influence the elongation at break of the filament.
- Three SMXL mixers from Sulzer / Switzerland were installed in the product line, the shear rate in the mixers being 28 sec -1 at a polymer throughput of 2500 g / min.
- the line diameter was chosen so that the shear rate in the free line was 7.9 sec -1 .
- the average residence time in the product line was about 3 minutes.
- the PTT melt was spun in a BN 100 spinning system from Lurgi Zimmer AG with a ring nozzle and radial cooling shaft.
- the hole density of the spinneret plate was 6.3 holes / cm 2 .
- the spinning beam temperature was 256 ° C., the total pressure loss of the melt until it emerged from the spinneret was 140 bar. Heat exchangers were not installed.
- the residence time in the nozzle pack was approximately 0.5 min.
- the melt filaments emerging from the nozzle plate were cooled in an amount of 1400 Nm 3 / h and at a temperature of 8 ° C. by means of cooling air guided radially inwards from the outside.
- the solidified spun threads were placed at a distance of 850 mm from the underside of the nozzle plate on a ring oiler and a water-oil mixture was applied so that the amount of water on the spun threads was about 25% by weight and a very stable thread run resulted ,
- the spinning take-off speed was 900 m / min. After the stripping, the spinning threads were deposited in spinning cans in the form of spinning cables by means of a reel mill.
- the separate stretching of the spinning cable was carried out in a fiber section in two stages.
- the spinning cables were then heat-set at slight relaxation, cooled, crimped, dried and closed Cut staple fibers.
- the production speed in the Fiber section, according to the speed of the roller mill on Outflow from the last stretching zone was 100 m / min.
- the intrinsic viscosities were determined on a solution of 0.5 g PTT in 100 ml of a mixture of phenol and 1,2-dichlorobenzene (3: 2 parts by weight) measured at 25 ° C.
- Melting point and glass point were determined by means of DSC at a heating rate of 10 ° C / min after the sample has been melted briefly and was immediately deterred.
- the titer and force-elongation properties of the fibers were compared with the Device set, Vibrotex and Vibrodyn, from Lenzing / Austria determined.
- the clamping length was 20 mm, depending on the preload weight of titer 100 mg / dtex and the test speed 20 mm / min.
- the LASE values (load at specific elongation) could be entered by entering the Reference stretches can be taken directly from the evaluation device.
- the Secant module was created by applying a secant to the elongation value (Elongation at break minus 45%), however at least 5%, and the Slope of this straight line in (cN / tex) with respect to 1% elongation change evaluated.
- the hot air shrink was in the heating cabinet at one Temperature treatment of 180 ° C over a dwell time of 20 min without Bias of the fiber determined.
- the crimp sheets were counted visually.
- the crimp values were determined according to the method and with the Vibrotex device from Lenzing / AT.
