Definitions

  • This invention relates to an apparatus wherein a fluid is ejected to a running multifilament yarn so that filaments constituting the running yarn are intermingled with each other by means of the energy of the fluid jet and so that the coherency of the yarn is increased. More specifically, this invention relates to an improvement of a yarn treating apparatus comprising a shell body which has a yarn treating chamber formed therein; an entrance of the chamber formed at its front end; an exit of the chamber formed at its rear end; and a jet nozzle, for ejecting a fluid jet, opening into a peripheral wall of the chamber.
  • a yarn treating apparatus of this type with a chamber which is circular in cross section is well known and in practical use for manufacture of an interlaced yarn.
  • This type of interlacing apparatus will be referred to as a "circular chamber type" apparatus.
  • a fluid jet ejected from the jet nozzle impinges on the opposite circular surface of the chamber and the fluid flows in separate directions to the right and to the left.
  • the separated fluids are apt not to equal each other in amount, whereupon unbalance of fluid flow occurs in the chamber and this causes a rotation to be imparted to a yarn passing through the chamber. Once the unbalance occurs it is difficult to return to a stable condition.
  • the continuous rotation of the yarn continuously imparts a false twisting thereto and reduces the interlacing action to the yarn.
  • the rotation of the yarn during the interlacing operation is required to be maintained as minimal as. possible, and the yarn is required to be subjected to a stable periodical and sufficient opening operation.
  • an interlacing apparatus having a chamber of which a cross sectional configuration is a semicircle has been proposed. This type of interlacing apparatus will be referred to as a "semicircular chamber type" apparatus.
  • the problem of the rotation of the yarn in the chamber during the interlacing operation is substantially eliminated, since the fluid jet ejected from the nozzle impinges upon a bottom flat surface of the chamber and the flat surface has a function of self revision to diminish the unbalanced flow of the fluid when it occurs.
  • the inventor of the present invention has conducted trials to produce an interlaced yarn by using the semicurcular chamber type apparatus and has found that an interlaced yarn thus obtained has substantially no false twisted portions therein and uniform interlacing density.
  • the interlacing pitch of the yarn is often undesirably large for the production of some kinds of woven fabrics such as a salt- and pepper-like fabric, a sprinkly coloured fabric, Melange fabric or Grandrelle fabric, which are manufactured by, for example, a water jet loom or an air jet loom.
  • the inventor of the present invention has also found that the consumption of compressed fluid of the semicircular chamber type apparatus must be comparatively large in order to obtain an interlaced yarn having a certain extent of coherency factor (CF-value).
  • An object of the present invention is to provide an interlacing apparatus which enables the easy production of an interlaced yarn having substantially no false twisted portions therein and having a comparatively small interlacing pitch which is suitable for a fabric such as a salt- and pepper-like fabric or a sprinkly coloured fabric.
  • Another object of the present invention is to provide an interlacing apparatus which enables the production of an interlaced yarn with a comparatively small amount of consumption of compressed fluid.
  • a further object of the present invention is to provide an interlacing apparatus which is simple in construction and easy to manufacture and assemble and which can be maintained easily.
  • the further portions of the second wall may each appear as an arc having the same radius as the semicircle and continuing the circumference of the semicircle, a tangent to the semicircle or part of a curve which would lie between the arc and the tangent.
  • the apparatus having a chamber formed in one of such cross-sectional configurations is preferable for preventing a unidirectional and continuous rotation of a yarn and for imparting a periodic, stable and sufficient opening operation to a yarn during interlacing treatment, and further for imparting interlacing having a comparatively small interlacing pitch to a yarn passing through the chamber.
  • the apparatus having a chamber formed in one of such cross-sectional configurations is also preferable for imparting interlacing to a yarn with a comparatively small consumption of compressed air.
  • the cross-sectional shape and dimension of the chamber may be selected in accordance with the yarn treating conditions such as a yarn delivery speed, tension in the yarn, the total denier of the yarn, the number of the filaments, the filament denier or the material of the filament.
  • the cross-sectional configuration of the chamber consists of an arc which is more than a semicircle and a chord which subtends the arc, the arc representing the second wall and the chord representing the first wall.
  • stability of the yarn motion within the chamber is enhanced.
  • the width of the first wall is greater than half the diameter, more preferably larger than the diameter, of the outlet of the fluid jet nozzle, and that the distance between the line passing through both ends of the semicircular portion and the first wall in a direction perpendicular to the first wall is greater than one twentieth, more preferably greater than one tenth, of the diameter of the semicircular portion, for obtaining much more enhanced stability of the yarn motion within the chamber.
  • a yarn string-up slit for introducing a continuous yarn to the chamber upon the commencement of the yarn treatment and for discharging the continuous yarn from the chamber upon the stoppage of the yarn treatment is formed on the body member, so that the yarn can be handled easily upon the commencement and stoppage of the yarn treatment.
  • the string-up slit should be formed on the semicircle portion of the second wall along the axis of the chamber, preferably at the intersection of the second wall and imaginary standard plane.
  • the stability of the yarn movement during the yarn treatment may be decreased or the running yarn may be expelled to the outside of the body member through the string-up slit while the yarn is being treated.
  • the diameter of the outlet of the fluid jet nozzle is larger than the width of the string-up slit in order to reduce the risk of yarn being expelled from the string-up slit.
  • the body member may include a first wall piece on which the first wall is formed, and a second wall piece on which the second wall is formed and which includes an entrance circular wall portion and an exit circular wall portion, the first and second wall pieces being detachably assembled to form the chamber.
  • the first wall is made of ceramic which is durable against abrasion
  • the second wall is made of metal, such as brass, steel or stainless steel, which is easy to manufacture precisely, so that abrasion of the first wall because of the yarn contact and fluid contact is small and so that the fluid jet nozzle can be formed precisely on the second wall.
  • the body member includes: one wall piece on which the first wall and a part of the second wall are provided; and another wall piece on which the remaining part of the second wall is formed, the two wall pieces being detachably assembled to form the chamberr, leaving between them a small gap to form the string-up slit for introducing and discharging yarn.
  • the chamber is formed from one body member made of ceramic, so that there is no meeting line on the wall of the chamber formed by the interface between two different body elements, a meeting line which occurs when the body member consists of two or more body elements and which sometimes causes catching of a filament or filaments of the yarn passing through the chamber.

  • the nozzle 9 for introducing the fluid jet is formed in the body member 2 and has an opening 10 at the external surface of the member 2. Referring to Fig. 2, a guide 11a is located upstream of the entrance 4 of the chamber 3 and a guide 11b is located downstream of the exit 5 of the chamber 3.
  • the yarn Y which has been subjected to the interlacing operation follows either one of fluid flows FR or FL flowing along the flat surface of the first wall 6 and is moved to either the right or left portion on the flat surface of the first wall 6.
  • the yarn Y is moved to the side of the first wall 6, it is raised along the wall of the segment portion 7R or 7L constituting the second wall 7.
