Definitions
- the invention relates to a profiled, fine-fibrillated filament yarn with a yarn viscosity RV of 40-55 and a strength of 30-45 cN / tex, in particular as a master yarn for texturing, and a method for producing the same.
- Profiled polyhexamethylene adipamide yarns are known (US-A-4801503).
- the known yarn is a smooth filament with a band-shaped fibril cross-section with a single titer of 2.8 dtex, which is suitable as a spandex substitute for the production of stockings due to its high flexural strength.
- the deep bending module is mainly attributed to the special profile.
- the well-known yarn is produced in two stages as a so-called polyamide LOY yarn.
- a polyamide LOY is to be understood as a filament which is wound up at spinning take-off speeds of up to approximately 1800 m / min; Polyamide POY is produced by spinning take-off speeds between 3700 and 5000 m / min.
- a disadvantage of polyamide LOY for the planned use of the present yarn can be seen above all in the low spinning speeds, which do not guarantee economical production.
- Another disadvantage is the poorer processing (thread breaks) of polyamide LOY at high speeds.
- the thread viscosity is measured in a known manner as relative viscosity (RV) in formic acid.
- a stocking section is knitted from any number of spinning reels of a solder.
- the stocking section is in a bath with the
- Alizarin light blue 4GL dye from Sandoz AG Basel stained in a known manner and, after drying, measured colorimetrically for the different remissions (brightnesses) of the sections originating from the different spinning reels. The coefficient of variation of the remissions is calculated in a known manner.
- the object of the invention is to provide a fine profiled original yarn for texturing or post-stretching, which is particularly suitable for warp threads in the weaving mill and does not have the dyeing disadvantages of the known profile threads.
- Another object is to provide a filament yarn that does not have a gloss known as "greasy" in the finished textile fabric and has an improved, very soft feel.
- the object is achieved according to the invention with a profiled thread, by means of a single fibril titer ⁇ 1.5 dtex, a high color uniformity (coefficient of variation) of ⁇ 2 and a width / length ratio B / L of the fibril cross section of 0.5 to 0.7.
- Profile ratio is the ratio of width and Length B / L, measured from the beginning of the leg for trilobal threads.
- filament yarn with a trilobal profile.
- threads with a generally flat profile can also be used.
- Polyhexamethylene adipamide granules with a relative viscosity of 41.5 are melted in a known manner in an extruder and added via a spinneret plate with 52 capillary openings per thread and a cross-sectional area of 0.1 mm 2 per capillary with a capillary length of 1.2 mm and a trilobal capillary cross-section a temperature of the spinneret plate of 276 ° C.
- the throughput through the nozzle plate is set so that the thread has a POY titer of 100 dtex, corresponding to a nominal titer of 78 dtex, which gives a fibril titer of 1.5 dtex.
- the cooled fibril bundle is converged and, at the same time, provided with a spin finish in a known manner, swirled and wound up directly at a spinning speed of 4200 m / min.
- the thread produced has a strength of 33 cN / tex with an elongation at break of 73%. Its relative viscosity is 44; the titer regularity is 0.8 U%.
- the coefficient of variation in dyeability is 1.02.
- Example 2 differs from Example 1 by the use of a spinneret plate with 68 capillary openings per thread, with a nominal titer of 78 dtex, a fibril titer of 1.14 dtex results.
- the resulting strength is 32 cN / tex with an elongation at break of 72%. RV and titer regularity are the same.
- Example 3 differs from Example 1 by the use of a spinneret plate with 34 capillary openings per thread, a POY titer of 56 dtex being set. This corresponds to a nominal titer of 44 dtex.
- the fibril titer is 1.29 dtex.
- the resulting strength is 32.7 cN / tex with an elongation at break of 69%.
- the spun thread has a relative viscosity of 40.9.
- the coefficient of variation in dyeability is 0.9.
- the titer regularity achieved is 0.8 U%.
- Fig.2 the fibril shape Fig. 1 shows the cross section of a capillary, where B is the
- Fig. 2 shows the cross section of a fibril
- the filament yarn according to the invention dtex 100 (78) f 52, has good textile properties in the fabric and also serves as an original yarn for texturing after
- Stretch to a plain yarn It is particularly suitable for use in weaving as warp yarn with its high dyeing requirements.
