Definitions

  • the invention refers to a yarn spool, to a yarn twisting process and a yarn twisting machine contributing to the function to which it is designed, with advantages and characteristics that are disclosed in detail thereafter.
  • the object of this invention falls on a yarn spool, concretely yarn of natural, synthetic or artificial textile fibers, in which twisting the said yarn wound on the spool is such that, when unwinding at "de filé” in a direction, the yarn twist is constant and is essentially zero tpm (twists per meter), while when unwinding in the opposite direction, the said twist is variable along the full spool and is equivalent to 2/(ID* ⁇ ) wherein ID is the spool wining/unwinding instant diameter in meters.
  • the object of the invention is the yarn twisting process that allows to generate a spool with the characteristics described.
  • Last are also object of the invention, the yarn twisting machines that allows to generate a spool having the characteristics described.
  • the field of application of this invention is within the sector of the textile industry of any type of yarns, namely delicate yarns such as glass fiber yarns.
  • twisting machines are known that, on an untwisted yarn or fibers strand (thereafter, untwisted or with zero twist yarn) apply given turns or twists per each meter of yarn or textile fiber (thereafter yarn with twist) and pick up the yarn with twist on a spool.
  • the said yarn pickup spool can be cylindrical-shaped, conical-shaped, double conical-shaped or others on a holder that can be a tube of cardboard or a reel-format spool container or a bottle or others.
  • a holder can be a tube of cardboard or a reel-format spool container or a bottle or others.
  • the format of the final spool is not limitative and depends on the further process with which the spool with twisted yarn will be used).
  • the twist applied on a yarn or fiber strand is defined as the turns of yarn on its own axis that are applied to it at 1m of the said yarn.
  • the twist unit in the metric system is turns/meter or tpm (twists per meter), although in the Anglo-Saxon system turns/inch is used or TPI in others.
  • the twist value is a characteristic that contributes with value to the yarn by providing breaking strength properties, a given stretching, S/Z twist direction, etc., that are generally expected to achieve a concrete aim in a further fabric, construction of a rope or others.
  • a 2-ply cabled yarn with a structure of 100tpm first twist in the S direction and 80 tpm second twist in Z direction that the same 2-ply cabled yarn with a first 100rpm twist in S direction and 80 tpm second twist also in S direction.
  • a same twisted yarn in a degree of twist or another also changes its mechanical properties, therefore, depending on the aim to which the said yarn will be designed and the properties that are required, a given degree of twist and an also given S/Z twist direction will be applied to it.
  • the said structure of the yarn with twist can be a strand of synthetic or artificial continuous fibers that are grouped in parallel (zero twist degree) forming an untwisted yarn and that is rolled on spools on a tube holder mostly of cardboard or plastic.
  • Some products such as for example some textile fabrics, require to be manufactured from twisted yarns in a given twist degree.
  • twisted yarn spools are generally placed on static structures, called creels, that support the spools with yarn by the inside of the tube and facilitate/guide the scutching of the yarns of the spools that are static on the creel towards the loom.
  • the said type of scutching is carried out with the spool static and drawing the yarn in the direction of the spool axis and is called "de filé" in which it is already known that this type of scutching makes that the structure of the twisted yarn varies, although such variation does not mean a substantial change on the yarn structure with respect to when it is twisted on the spool compared with when it is scutched and it is perfectly accepted in a great percentage of textile processes and products.
  • the scutching effect modifies the yarn structure as for twists, because in the scutching at "de filé” certain twists are obtained in a given direction, the yarns being fed to the following process not in conditions of zero twist yarn.
  • the textile sectors that use this type of spools and scutching generally also accept this effect without any problem.
  • the scutching speeds are lower and limit the productivity of the process because the inertias generated by the spools rotation movement and the yarns tensions are very high when the spools are full of yarn.
  • the spool of yarn of natural, synthetic or artificial textile fibers, the process of yarn twisting and the yarn twisting machine that the invention proposes are configurated as an utmost solution to the above-described problems, the characterizing details making it possible and that distinguish them are conveniently appearing in the final claims attached to this specification.
  • the format of the spool that can be cylindrical-, conical-, double conical-shaped, with plates (reel), etc., is not affected by the characterization of the spool provided that it meets the requirement of twist value described.
  • the yarn twisting process essentially comprises the following steps.
  • twisting machines that allow to generate a spool as that described before applying the also described twisting process.
  • FIG. 1A shows both schematic elevation views of two examples of spool object of the invention being scutched in opposite directions.
  • a spool can be seen where the scutched yarn at "de filé” presents an essentially 0 twist (ß) while in the figure 1-B the scutched yarn at "de filé” of the same spool presents a (ß') twist different from a 0.
  • a primary spool or delivery spool (2) with a multifilament yarn (H), for example, of polyamide of titer 110 Tex and without twist, is processed in a twisting machine (100) on a container that will be the holder of the spool (1) of this invention.
  • H multifilament yarn
  • the pickup spool (1) is acquiring a larger diameter, the twist that the rolled yarn shall have will be different and will be within the alfa75 and the alfa200 values.
  • the twisting machine (100), whichever the technology used, shall know, during the full twisting process, the instant diameter (ID) of the pickup spool (1) of twisted yarn as the said instant diameter (ID) is changing along the winding process.
  • FIG 2 a schematic representation of a first example of the machine (100) can be seen, concretely a ring machine with a delivery spool (2) of yarn at "roulé”.
  • the yarn (H) exiting from the delivery spool (2) of yarn having no twist (yarn twist value prior to the twisting means ( ⁇ ) 0), that means that scutching does not add twist.
  • FIG. 1 Another example of the machine (100) can be seen, concretely a ring machine with a delivery spool (2) of yarn that scutches at "de filé".
  • the machine comprises a delivery spool (2) of yarn (H) at 0 twist, twisting means that apply to the yarn (H) a yarn twist ( ⁇ ), a pickup spool (1) of yarn (H) with a value of twist of the rolled and already twisted yarn ( ⁇ ), means to know the instant diameter (ID2) of the delivery spool (2), means to know the instant diameter (ID) of the pickup spool (1) and means to modify the twist ( ⁇ )applied to the yarn in the twisting means.
  • twisting means that apply to the yarn (H) a yarn twist ( ⁇ )
  • ID2 instant diameter
  • ID instant diameter
  • the yarn exiting from the yarn delivery spool (1) has a twist ( ⁇ ) consequently to the enwinding
  • the yarn twist value prior to the twisting means ( ⁇ ) depends on the type of the scutching direction (S or Z).
  • twisting means apply a twist ( ⁇ ) in the S direction
  • rpm of the spool (1) ⁇ (tpm)* linear speed (m/min)
  • ID winding/unwinding instant diameter
  • twisting means apply a twist ( ⁇ ) in the S direction
  • the machine comprises a delivery spool (2) of yarn (H) at 0 twist, twisting means that apply to the yarn (H) a twist to the yarn ( ⁇ ), a pickup spool (1) of yarn (H) with a value of the rolled yarn ( ⁇ ), means to know the instant diameter (ID2) of the delivery spool (2), means to know the instant diameter (ID) of the pickup spool (1) and means to modify the twist ( ⁇ ) applied to the yarn in the twisting means.
