    • D06B23/06—Guiding means for preventing filaments, yarns or threads from sticking together

Definitions

  • This invention relates to a method for preparing chains or fractions formed from continuous thermoplastic yarns which are substantially completely drafted, and suitable for use on looms for fabric production.
  • the method is characterised by starting from continuous thermoplastic yarns with filaments which are substantially parallel but not completely drafted, these being drafted and simultaneously sized by immersion into a liquid generally containing a cohesion agent for the filaments which constitute the actual yarn.
  • thermoplastic polymers for textile use comprise spinning the polymer in its molten state into filaments, cooling it, combining the filaments to form a yarn and then drafting them.
  • yarns collected from drafting and drafting-twisting machines must be subjected to a sizing operation in order to prevent breakage of the individual filaments due to mechanical stresses during weaving.
  • This operation consists of impregnating the yarns with special sizes according to the following process: the beams on which the previously warped yarns are wound are positioned on beam support creels.
  • the yarns, parallel and properly ordered, are passed through suitable apparatus provided with an impregnation tank and squeezing rollers, then through hot air driers or infrared ovens, or over hot cylinders, and are finally collected again on beams by a winding machine.
  • the method of the present invention enables an incompletely drafted yarn, as would be obtained from the spinning stage of the said known process, to be used as the starting yarn for preparing said sized chains or fractions for weaving, thus dispensing with the normal stage in which the yarn is operated on by a drafting or drafting-twisting machine.
  • the new method combines the two separate drafting and sizing stages into a single stage, with obvious technical and economical advantages.
  • the present invention thus enables the separate drafting and sizing operations of the prior art to be combined into a single simultaneous drafting and sizing operation.
  • the yarns are dried by passage through ovens (F) which can be of various types, and/or over hot cylinders (G) which also exert a thermal stabilising action on the yarn, and are finally collected on beams or the like by means of a winding machine (E).
  • a modification to the present method consists of feeding the yarn from beams, small beams, large reels or any other support prepared in a previous passage by a winding machine, instead of directly from the cops loaded on to a creel.
  • the yarns are warped at a speed of 300 metres/minute and with a tension of 10 grams after checking irresularities with a Lindley apparatus, then collecting them in a single fraction of length 40,000 metres on a beam of height 180 nm.
  • the fraction warped in this manner is placed on an unwinding stand, and the yarns are passed through the blades of a rectilinear comb.
  • the yarns are anchored and dragged with a tension of 10 grows by a system of three rollers, which rotate in unison at a constant peripheral speed of 130 metres/minute.
  • the yarns are then immersed in a tank containing a bath of hot size consisting of a 10%aqueous solution of Adex-Twe acrylic size of the firm Cesalpinia, kept at a constant temperature of 90°C.
  • a system of three drafting and squeezing cylinders which rotate in unison with a constant peripheral speed of 200 metres/minute acts simultaneously on all yarns so that they are drafted to a ratio of 1.538 relative to the feed.
  • the aqueous sizing solution remaining on the yarns is about 80% of the weight of the dry yarn.
  • the yarns are then dried by passing then through hot air ovens and are then fixed thermally by being passed over and in contact with five hot rotating cylinders kept by steam at a temperaure varying from 105°C at the first to 90°C at the last cylinder.
  • the speed of the hot cylinders is kept slightly less than 200 m/minute so as to allow a certain shrinkage in the length of the yarns before fixing.
  • the yarns are wound on beans of height 180 mm in eight fractions of 5000 metres each.
  • the eight sized fractions are combined on a weaving beam of height 1550 mm with a total of 6400 yarns.
  • the beam is loaded on to an LV/51 Nissan water loom and wefted with texturised polyester yarn of count 56 Dtex and 24 filaments, at a speed of 360 beats/minute, with a cloth weave and with a density of 33 wefts/cm.
  • the fabric is then scoured in full width in a continuous scouring and washing machine at a speed of 15 m/minute.
  • the scouring bath consists of water softened by treatment with ion exchange resin, kept at 90°C and containing 10 cc/ litre of 36/38 Be caustic soda, 5 cc/litre of a detergent and 0,5 g/litre of a sequestering agent. This is followed by two wash baths with hot and cold water, and neutralisation with acetic acid.
  • the scoured fabric is then dyed in a jet cord dyeing machine (Messera).
  • the dispersed dye used is Dispers Blue Color Index 056, dissolved in a bath of softened water with a dye concentration of 2 of the weight of the fabric and with the addition of 2% of an evener and 0.2% of a dispersing agent.
  • the pH is adjusted to 4.5 by adding formic acid, and stabilised with monosodium phosphate.
  • Dyeing is carried out with the following temperature cycle: starting from 60°C, the temperature rises to 130°C at a rate of 1°C/minute; 130°C is maintained for 20 minutes; the temperature falls to 80°C at a rate of 1 C/minute; the dyeing bath is then discharged and the fabric washed with hot and cold water.
  • the fabric centrifuged and dried in hot air, is passed through a stenter machine and thermo-fixed at 180°C at a speed of 25 m/minute.
  • a fabric is obtained having a height of 140 cm with a weight of 55 g/m 2 and a chain shortening, from raw to finished, of 5.5/6%.
  • a high uniformity and compactness of the chain yarns is noted, with total absence of lucid yarns.
  • the feed cylinders are rotated with a peripheral speed of 126 m/minute, whereas the drafting-squeezing cylanders rotate at 200 m/minute, with a drafting ratio of 1.587.
  • the sizing bath is constituted this time by an 11% aqueous solution of Kodak 9519 polyester size kept at a temperature of 90°C.
  • the temperature of the fixing cylinders varies between 105°C and 90°C, and their peripheral speed is slightly less than 200 m/minute.
  • the sized fractions are then combined and woven in the sane manner as in the preceding example.
  • Scouring, dyeing and fixing are then carried out as in the preceding example, the only difference being that the scouring bath contains 0.5 g/l of sodium carbonate instead .of caustic soda.
  • a finished fabric of height 140 cn is obtained, with a weight of 53 g/m 2 and a chain shortening, from raw to finished, of 5.5/6%.
  • the feed cylinders are rotated at a peripheral speed of 110 m/minute, whereas the drafting-squeezing cylinders rotate ot 200 m/minute, with a drafting ratio of 1.818.
  • the sizing bath is the same as in example 2, and the fixing cylinder temperature varies from 110°C to 90°C.
  • the sized Practions are then combined and woven in the same manner as in the preceding example.
  • a finished fabric of height 140 cm is obtained, with a weight of 56 g/m 2 and a chain shortenin;, from raw to finished, of 6%.
  • FCY partially orientated lucid polyester yarn
  • the yarns are passed through a perforated warping table and then through the blades of a rectilinear comb.
  • the yarns are then anchored and dragged with a tension of 11 grams by the feed rollers of the simultaneous drafting and sizing system of the preceding examples.
  • the feed cylinders are rotated at a peripheral speed of 117 m/ minute, while the drafting-squeezing cylinders rotate at 200 m/minute with a drafting ratio of 1.709.
  • the sising bath is constituted by a 10% aqueous solution of Wisacril PNS acrylic size of the firm Bozzetto, kept at a temperature of 90°C.
  • the temperature of the fixing cylinders varies between 115°C and 95°C, and their peripheral speed is slightly less than 200 m/minute.
  • the finol average characteristics of the drafted and sized yarn are as follows:
