Definitions

  • the present invention relates to an apparatus and method for the finishing of yarns.
  • the present invention relates to an apparatus and method for performing operations of finishing such as, in particular, the dyeing of yarns.
  • the present invention is particularly useful when adding to the yarns various types of chemical substances suitable to give multifunctional properties such as waterproofing, mechanical strength, and flame resistance.
  • the processes for dyeing yarns include bobbin dyeing or hank dyeing.
  • a dipping technique is used that involves the use of reactive dye and the insertion of the bobbins inside special tanks containing water under pressure and at a predetermined temperature.
  • the bobbin dyeing can define an uneven colouring depending on the various portions of yarn wound on the bobbin.
  • dipping technique needs to use a substantial amount of water at high temperature and under pressure. Consequently, dipping dyeing is particularly costly both in terms of energy and of water consumption.
  • hank dyeing systems are provided both for the dipping systems similar to those mentioned above, and for spray dyeing systems in which the colour is sprayed onto the hanks suitably supported on special frames.
  • the dyeing of the hank may cause an uneven colouring derived from the positioning of the yarns with respect to the colourant delivery nozzles.
  • a further drawback related to both technologies (either dipping or spraying dyeing) described above is the impossibility to use the dyeing systems in order to add various types of chemical substances to the yarn. Such operations are mostly made with specific equipment and on dedicated finishing lines.
  • the technical task underlying the present invention is to devise an apparatus and method for the finishing of yarns, which are able to solve the above drawbacks.
  • the object of the present invention is to provide an apparatus and method for the finishing of yarns which is able to achieve homogeneous dyeing of the yarns.
  • a further object of the present invention is to provide an apparatus and method to perform on yarns both dyeing and additivation operations with chemical substances suitable to give the yarn specific multifunctional features.
  • Yet another object of the present invention is to provide an apparatus and method for the finishing of yarns which is structurally simple, effective in terms of production speed, and cost-efficient, while also being able to reduce as much as possible the possible environmental impact both in terms of energy consumption and consumption of the raw materials used (i.e. water).
  • the numeral 1 generally refers to an apparatus for the finishing of yarns.
  • the present invention is particularly useful in finishing operations of yarns, such as the dyeing and the additivation of chemical substances suitable to give the yarns specific multifunctional features.
  • the multifunctional features include waterproofing, flame resistance, and mechanical strength.
  • the apparatus 1 comprises a feed station 2 for at least one yarn "Y" to be treated.
  • the feeding station 2 comprises at least a support frame 3 for a plurality of spools 4 on which the respective yarns "Y" are wound.
  • the bobbins 4 are advantageously supported on the frame 3 rotatably, to facilitate the unwinding of each individual yarn "Y" from the spool 4.
  • the unwinding action of each yarn "Y” implies the rotation of the spool 4 around a respective longitudinal axis.
  • the frame 3 is preferably like a picture frame, and can support any number of spools 4.
  • a frame 3 suitable to support four spools 4 (and consequently four yarns) is illustrated purely by way of example and without limitation. It should, however, be specified that the shape of the frame and the number of support frames for the spools can be different according to the number of yarns "Y" to be treated.
  • the yarns "Y” are then placed in traction and unwound along a line of advance 5 and in a direction indicated by "D".
  • the yarns "Y" in the line of advance 5 are fed parallel to each other and along a respective substantially horizontal axis.
  • a collecting station 6 of the yarn "Y” Downstream of said line of advance 5, a collecting station 6 of the yarn "Y" is located.
  • a collecting station 6 includes a winding roller 7 rotatable about a horizontal axis and perpendicular to the direction of advance "D" of the yarns.
  • the yarns "Y” treated along the line 5 into individual hanks "M” are collected.
  • the rotation of the roller 7 that winds the yarns "Y” therefore determines the traction action of the same yarns "Y" that are unwound by the respective spools 4.
  • the feeding station 2 also comprises at least one tensioning device 8 associated to the yarn "Y” to tighten the yarn along the line of advance 5 to a predetermined tensioning value as a function of the features and dimensions of the yarn "Y".
  • the feeding station 2 comprises a plurality of tensioning devices mounted on the frame 3 and each of which is aligned with a pool 4 of a respective yarn "Y".
  • each tensioning device 8 comprises at least one restraining roller 9 around which the thread dipping is partially wound upstream of the line of advance 5.
  • the restraining roller 9 is rotatably engaged on a supporting element 10, which is engaged on the frame 3 and has a further diverter roller 11 disposed upstream of the restraining roller 9 with respect to the direction of advance of the yarn "Y".
  • the restraining roller 9 has a brake system (not shown or described in detail because it is of a known type) in order to implement resistance to the advance of the thread "Y" towards the collecting station 6. This resistance is determined according to the predetermined tensioning value to be obtained.
  • the tensioning device 8 further comprises detecting means 10a and adjustment means (also not described and illustrated in detail since of known type) adapted to control the resistance action of the roller 9.
  • detecting means 10a and adjustment means also not described and illustrated in detail since of known type
  • These means are constituted by a sensor for detecting the yarn tension and by appropriate interface members that allow manually setting and displaying a predetermined tensioning value.
  • the tensioning device 8 provides the automatic adjustment of the tension of the yarn "Y” by the restraining action of the roller 9 in an automatic and controlled way. This adjustment action of the tensioning value (set manually) is carried out taking advantage of the features of the yarn "Y" during the continuous feeding along the line 5.
  • Each single yarn is controlled during the step of advance and maintained at the optimum tensioning in order to perform the finishing operations and, at the same time, to avoid any damage to the yarn itself.
  • this specific control on each yarn allows the use of yarns "Y" of any type (material) and count, also those having a very high fineness.
  • the apparatus 1 further comprises distribution means 12, for distributing a finishing additive that is arranged along the line of advance 5.
  • the distribution means 12 deliver on each yarn "Y” fed along the line of advance 5 a respective additive that can be a dye to impart a specific colour to the yarn treated "Y".
  • the distribution means 12 may be adapted to distributing on the yarns "Y” an additive capable of imparting final specific features of the yarn.
  • the distribution means 12 comprise at least one delivery device 13, for delivering the finishing additive, equipped with a chamber 14 (only visible in the partial cutaway view of Figure 3 ) for the passing of the yarn "Y".
  • the chamber 14 of the dispensing device 13 defines an inlet opening 15 and an outlet opening 16 of the thread Y" for passing through the chamber 14 itself.
  • the distribution means 12 comprise a plurality of dispensing devices 13, arranged in series along the line of advance 5 of the yarn. In this circumstance, note that each yarn "Y" is fed in sequence inside the chamber 14 of each dispensing device 13.
  • dispensing devices 13 are illustrated that are arranged one after another along the line of advance 5.
  • the dispensing devices 13 may be arranged to feed the same additive or substances different between each other.
  • the number of dispensing devices 13 and the type of additive fed by each device 13 may be different according to the various production requirements of the yarn "Y".
  • the first dispensing device 13 is shown in a partial cutaway view to better show the chamber 14 disposed within each device 13.
  • each chamber 14 there is a spray nozzle 17 adapted to distribute a jet of additive on the yarn "Y" while it is being continuously fed.
  • the dispensing device 13 comprises a plurality of spray nozzles 17 mounted on a support member 18 that is movable inside the chamber 14 to direct the jet of additive towards the yarn "Y" intermittently.
  • the support member 18 comprises a rotary drum that is rotatable about a rotation axis "X" transverse to the direction of advance "D" of the yarn "Y".
  • the nozzles 17 are arranged on a peripheral area of the drum 18 to be facing the yarn "Y” and for direct the spray of additive to the yarn "Y" itself periodically.
  • the distribution means 12 further comprise a comb 19 disposed between the feeding station 2 and the first dispensing device 13.
  • the comb 19 is mounted facing the inlet opening 15 of the first dispensing device 13 to guide the yarns "Y” maintaining them horizontal and close to each another along the feed line 5.
  • the comb 19 maintains the yarns "Y” suitably spaced apart along the line of advance 5, to allow the correct distribution of the additive on the yarns themselves within the individual chambers 14.
  • the presence of the comb 19 is also required to ensure the smooth passage of the yarns "Y" through the openings 15, 16 and each single device 13.
  • An object of the present invention is also a method for the finishing of yarns "Y" usable with the apparatus 1 described hereinabove.
  • the method comprises the steps of: feeding at least a yarn "Y" to be treated along the line of advance 5 and distribute one or more finishing additives on the yarn along said line of advance 5.
  • the step of feeding the yarn comprises the substep of stretching the yarn along the line of advance 5 to a predetermined tensioning value depending on the features and dimensions of the yarn itself.
  • the step of stretching the yarn is implemented by the resistance imparted by the restraining roller 9 around which the yarn is partially wound. Therefore, the roller 9 brakes the advance of the yarn towards the collecting station 6 depending on the predetermined tensioning value that is set and adjusted according to the structure, the features and dimensions of the yarn.
  • the step of distributing the finishing additive on the yarn "Y" is implemented by passing the yarn in a sequential manner in a plurality of dispensing devices 13 for the additive.
  • the additive is sprayed on the yarn "Y" intermittently.
  • the yarn "Y” exiting the last dispensing device 13 is collected by a roller 7 to form respective hanks "M".
  • the formation of each hank "M” is preferably implemented by further guide elements (not illustrated since of known type) provided on the roller 7 to allow the correct positioning of the respective yarns "Y" on the roller 7.
  • the step is implemented to fix the additive previously distributed on the yarn "Y” collected in hanks "M” by means of a vaporization step at a predetermined pressure and temperature.
  • This step is implemented by transferring the hanks "M” inside a respective steaming to allow for the fixing step.
  • the apparatus 1 and method thereof that is able to achieve a homogeneous dyeing on the years "Y".
  • the present invention allows for treating any type of yarn regardless of its structure and size. This advantage is thanks to the presence of each tensioning device 8 active on a respective yarn. This device 8, in addition to maintaining each yarn in the optimum tensioning condition for feeding and finishing, also preserves the yarn from any tearing and damage.
  • the apparatus 1 is very versatile and usable not only in dyeing operations but also in any finishing operation which includes the distribution of chemical additives on the yarn.
  • the present invention is particularly advantageous when the aim is to obtain multicoloured dyeing on the yarn "Y” with a "random” and repeatable effect on the individual yarns.
  • the apparatus 1 can advantageously be used to give the yarn "Y" specific multifunctional features.
