Definitions

  • the present invention is concerned with a method suitable for treating knitted or woven broad materials especially jersey cloth, taffeta, carpet or like materials, which easily develop creases or fixed wrinkles and accordingly, dye-patches in dyeing operations-without causing any undesirable effect of treatment including the aforesaid dye-patches.
  • the invention also relates to an apparatus suitable for putting the aforesaid method into practice.
  • an important object of the present invention to provide a method for treating, with a liquid, knitted or woven materials, especially broad knitted fabrics and other broad fabrics such as tafieta and carpet, which method is free of the aforesaid disadvantages and shortcomings and minimizes the effect of the current of the treating liquid on the material being treated and also minimizes the tension applied to the material as the latter is transferred from one place to another in the treating apparatus, thereby improving the quality and the feel of the treated material, and also to provide an apparatus suitable for putting the method of the present invention into practice.
  • Another object of the present invention is to provide a method for treating, With a liquid, knitted or woven broad materials, and an apparatus therefor, which are both relatively simplified and which permit the treating operation to be performed for a relatively short period of time and which are suitable for such treating operations, with a liquid, as are performed at a high temperature and a high pressure.
  • the present invention contemplates the carrying-out of a treatment, with liquid, of broad fabrics by the use of a treating apparatus which comprises: a vessel having a concave cross sectional configuration and having a transverse length perpendicular to said vertical section and suitable for receiving the breadth of a broad material to be treated; and inner assembly located inside said vessel and having a convex cross sectional configuration substantially corresponding to the concave configuration of the vessel and including therein one or more groups of fluid channels and also including motordriven pumps for these channels.
  • One of the channels in each group being intended for supplying fresh liquid into the vessel, one another being intended for successively draining a part of the liquid from said up-going path and the remainder being assigned for injecting the drained liquid into the down-going path, all of which operations being effected by said pump, said vessel and said inner assembly forming a down-going path and an up-going path which are joined together to form a continuous single passageway for both the material under treatment and the treating liquid to pass therethrough; and feeding means provided above said vessel for feeding the material being treated from the up-going path into the down-going path.
  • the broad material is subjected to a circulatory treatment with a liquid which is also circulated through the apparatus, said treatment being effected by feeding the transversely spread materialwhile being longitudinally foldedinto the downgoing path from thereabove after drawing it up from said up-going path, and thus, the material is treated with the liquid while it passes through the apparatus in the form of being spread transversely.
  • the material under treatment became rope-like in some portions thereof during the passage of the material through the apparatus, resulting in a decrease in the breadth of the material-though the extent and number of these portions varied with the individual instanceswithout the initial transversely spread state of the material being retained.
  • jersey fabrics for example, especially those made of acrylic synthetic fibers among all synthetic fibers
  • the materials being treated will lose their initial firmness and become soft during their circulation through the treating apparatus, and will turn into masses. These masses not only hamper the sound operation but also constitute a cause for the development of creases or fixed wrinkles in the treated materials.
  • the present invention has been worked out to obtain the desired effect of treatment, with a liquid, of woven or knitted broad materials-which has been impossible with the prior artby circulating such a broad material through a treating apparatus while retaining the fully spread state of the material throughout the treating operation.
  • the vessel incorporated in the apparatus of the present invention which is intended for the treatment of broad fabrics with a liquid is of an upwardly concave cross sectional configuration and is of a certain transverse lengthextending in the direction perpendicular to the aforesaid cross section-sufficient for receiving the breadth of the material to be treated.
  • This transverse length of the vessel is necessary in the treatment of a broad fabric, since in the treatment the fabric is received in the form of being spread transversely relative to its length.
  • the term certain transverse length is, therefore, used in this specification in the aforesaid sense.
  • the inner assembly which is received inside the vessel is of a downwardly convex vertical sectional configuration corresponding to, but smaller than the concave vertical sectional configuration of the vessel.
  • This inner assembly also is of a certain transverse length-in the direction perpendicular to the cross section of this assembly.
  • the concave vessel and the convex inner assembly are arranged so that there are formed, between the concave inner surface of the vessel and the convex outer surface of the inner assembly, a down-going path and an up-going path with extends continuously from said down-going path, both of which paths jointly forming a generally U-shape continuous passageway for the smooth passage therethrough of the material to be treated and of the treating liquid, as will be clearly understood by referring to the accompanying drawings.
  • the aforesaid concave and convex cross sectional configurations of the vessel and the inner assembly are not limited to any particular configurations, provided that these two members jointly can form an appropriate passageway for both the material to be treated and the liquid.
  • the inner assembly is provided, inside thereof, with a plurality of sets of channels, one of the channels in each set communicating with the up-going path and another one communicating with the down-going path, of the material being treated and the treating liquid.
  • a feeding means is provided above the vessel for drawing up the material being treated from the up-going path which is one of the paths constituting the aforesaid U- shape continuous single passageway.
  • the feeding means is usually comprised of a reel or reels which are driven from an appropriate driving source.
  • the feeding means may be replaced by any desired device provided that it is capable of performing the operation of drawing up and feeding the material which is to be treated.
  • the type or the number of the reels or the like which are used there is no limitation on the type or the number of the reels or the like which are used.
  • a suppressing roller may also be provided in order to prevent the slipping of the material running on the reels.
  • the material to be treated is transferred by the feeding means in such a way that, the material is introduced, in a longitudinally folded state, into the treating liquid contained in the down-going path which constitutes one of the U-shape passageway.
  • the material which has been introduced into this down-going path tends to stay relatively stationary on the surface of the liquid by virtue of its own buoyancy and also of the buoyancy afforded by the air contained in the material per se.
  • the portions of the materialwhich are fed successively into this downgoing path in the same fashion following the preceding portions which have been already introduced into the down-going path in the form of longitudinally folded state will pile upon said preceding folded portions of the material that have been already introduced into said path.
  • the weight of the portions of the material that have piled up on the previously introduced portions will cause the latter portions to be pushed downwardly into the treating liquid contained in the path.
  • the treating apparatus of the present invention during the aforesaid operation, arrangement is provided so as to continuously drain from the upgoing path, a part of the treatment liquid contained in this path and to supply the same into the down-going path to circulate the treatment liquid through the apparatus.
  • This arrangement comprises one or more groups of channels formed within the inner assembly, the channels in each group leading from the up-going path to the downgoing path, and one or more pumping means for these channels.
  • the present invention is concerned basically with an entire process of liquid-treatment of a broad fabric, such as taffeta carpet, which is performed While retaining the breadth of the fabric in its transversely fully spread condition continuously for the entire course of treatment.

  • Numerals 4 and 5 represent reels which are provided above the vessel 1.
  • Numerals 6, 7 and 8 represent guide rods, respectively.
  • Numeral 9 represents a means for longitudinally folding the knitted or woven broad material to be treated and is provided below the reel 4 and above the down-going path.
  • This means 9 is caused to unake reciprocating movement in the directions indicated by the arrow B, by virtue of the reciprocating circular movement of the shaft 10 to which said means 9 is secured.
  • the material A is longitudinally folded as it is brought into contact with this means 9 after being fed from the reel 4.
  • the following description will be directed to the manner in which the material A to be treated is transferred from one place to another within the treating apparatus.
  • a knitted or woven broad material A is applied-in the form of being transversely spread (without being transversely folded as it is so with an ordinary winch)-to the treating apparatus as shown in FIG. 1, and that the vessel is filled with a treating liquid up to the level LL
  • the material A is longitudinally folded successively by the folding means 9, and the folded material is allowed to drop by its own weight into the vessel, retaining the form of being longitudinally folded.
  • the distance between the folding means and the treating liquid is controlled as desired depending on the factors such as the type of the fabric to be treated.
  • the mode of folding effected by the folding means 0 may be varied by adjusting the magnitude of the reciprocal pivotal movement of the shaft 10.
  • the material A is driven to ascend through the up-going path while passing along the wall surface, on the right side of the inner assembly, approaching, by virtue of its own buoyancy, closer to the surface of the treating liquid contained in this path.
  • this material travels closer to the surface of the liquid, it turns into a state in which the material can be easily drawn upwardly.
  • the material reaches the surface of. the liquid, a portion of the material emerges from the surface of the liquid. This portion of thelmaterial is then drawn up by the reel 5 and fed to the rec 4.
  • the width (II-L of the down-going path in this section thereof desirably is about 2 times or less, preferably 1.5 times or less, that of the width of the longitudinal folds of the material.
  • the up-going path which is located on the side at which the material is drawn up from the treating liquid, the material does not tend to become entangled, and what is more, it is desirable that the longitudinally folded material is unfolded in this particular section of the passageway 3 because the unfolding of the material in the upgoing path contributes to the prevention of the development of creases and fixed wrinkles. For this reason, it is desirable that the up-going path have a width (L -L which is greater than that (LL of the down-going path located on the side at which the material is introduced into the apparatus. It is desirable to set the down-going path to up-going path width proportions (L -L :LL at 1:1.5-1 :2 or greater than this range.
  • the shape of the upper surface of the inner assembly 2 may have a horizontal upper surface, but, desirably, the surface is inclined downwardly as it extends from the upper end of the up-going path from which the material is drawn up toward the upper end of the down-going path into which the material to be treated is introduced.
  • the treating liquid which is carried by the portion of the drawn-up material and which drops in the form of drips onto the upper surface of the inner assembly is allowed to flow into the down-going path located on the side at which the: material is introduced into the apparatus and, at the same time, the edge of the inner assembly located adjacent to the tilted upper surface thereof and facing the down-going path performs the longitudinal folding of the material as the latter is introduced into this path after contacting the edge of the inner assembly.
  • This falling of the drops of treating liquid facilitates the smooth slithering of the material along the upper surface of the inner assembly.
  • the treating apparatus equipped with an inner assembly of this type is suited especially for the treatment of such a material as pile-carpet which carries with it a large amount of treating liquid as the material is drawn up from the treating liquid and which, as a matter of course, gives out a large amount of drops of liquid falling onto the upper surface of the inner assembly.
  • the portions of the material which are about to pile are spontaneously folded longitudinally immediately before falling onto the liquid surface.
  • FIG. 3 shows an example of the folding means, in which an ordinary J-shaped box 17 is used.
  • FIG. 4 shows a modified example in which this J-sh-aped box 17 has a foremost end portion curved more intensivel inwardly so as to impart greater pressure to one side of the dropping material and to produce folds.
  • FIG. 5 shows an instance in which a similar folding effect is obtained without the provision of any particular folding means, or more specifically, in this instance, the reel 4 is positioned farther toward the right hand, away from the position of the reel 4 seen in FIG. 1 so that the reel 4 is disposed just above the mid portion of the inner assembly 2.
  • FIG. 6 shows a modified example of the reel 4.
  • the reel 4 is oval-instead of being circularin its cross sectional shape.
  • this reel 4 By the use of this reel 4, the material which is fed from this reel is folded longitudinally when the material contacts the reel 4 which is rotated.
  • the feeding of the material is effected by two reels 4 and 5. It should be understood, however, that there is no limitation on the number of the feed reels to be employed.
  • the feeding of the material effected by the reels may be facilitated by the provision of a plurality of guide rods 6, 7 and 8 as shown in FIG. 1. It is, however, desirable to provide means for adjusting the lateral position of the travelling material-relative to the length of the reel 5which may be displaced sideways relative to the direction of the travel.
  • Numeral 15 in FIG. 2 shows an example of this position-adjusting means.
  • This means 15 is operative in such a way that it moves the reel 5 lengthwise by virtue of, for example, an oil or hydraulic pressure afforded by said means to thereby adjust the lateral position of the material so that the latter is maintained in its correct position. It is needless to say that the correction of the lateral position of the material may be effected by tilting the reel 5 in either of the opposite lengthwise directions as required.
  • the channels 12, 12a represent the suction channels of the pumps 14, 14a. These suction channels 12, 12a, are provided in the inner assembly on the side leading to the up-going path 31), and preferably, these channels are provided in the bottom portion of said upgoing path 3b. Channels 13, 13a, are intended for injecting, by the driving force afforded by the pumps 14, 14a, the treating liquid-which has been sucked into the suction channels by these pumpsinto the downgoing path 3a. These liquid-injection channels 13, 13a, are provided in the inner assembly on the side leading to the down-going path, and preferably, these channels are provided in the upper portion of this path.

For example, there may be provided two liquid injection channels 13 and 13 for a single liquid suction channel.
  • Pumps 14, 14a, 14b are adapted to continuously drain a part of the treating liquid from the up-going path 3b and to positively inject the same into the down-going path 3a to elevate the level of the liquid surface L-L higher than the liquid surface L -L This difference in the levels of the liquid surfaces in these two paths will force the entire liquid contained in the passageway 3 to form a current flowing from the down-going path into which the material to be treated is introduced toward the up-going path from which the material is drawn up.
  • the material is imparted a travelling drive and, what is more, the portion of the liquid which contacts the material is successively replaced by another portion of the liquid.
  • the provision of a plurality of liquid injection channels 13, 13a, 13b contributes to making the currents of the treating liquid injected through the plurality of injection channels into the down-going path constant and uniform for the entire transverse length of the vessel, without the injection being confined locally with respect to the transverse length of the down-going path.
  • This fashion of liquid injection contributes greatly to the improvement of the effect of the treatment.
  • the present invention eliminates the occurrence of un-even dyeing, and as a result, the development of undesirable dye-patches in the treated material is obviated.
  • the arrangement that the down-going path located on the side at which the material is introduced into the vessel is narrow in width and that the up-going path located on the side at which the material is drawn up is greater in width than that of the former insures the diffusion of the current of the treating liquid entering into the up-going path.
  • This diffusion of the liquid current contributes to the longitudinal unfolding, in the up-going path, of the folded material.
  • the pumps which are used in the present invention must produce a force only to an extent sufiicient for accomplishing the operation consisting of continuously draining a part of the treating liquid from the up-going path located on the side at which the material is drawn up and injecting the same into the down-going path located on the side at which the material is introduced into the vessel.
  • the pumps are not required to produce a particularly great pressure.
  • the pumps need not be centrifugal pumps.
  • this perforated plate 16 also plays the role of preventing the derangement, in the up-going path of the liquid current caused by the suction of the pumps. Furthermore, this perforated plate 16 facilitates the smooth entry of the treating liquid into the suction inlets of the pumps.

  • the materials being treated are subjected to very little amount of tension either longitudinally or vertically thereof. Therefore, there is hardly formed any crease or fixed wrinkle in the treated material, resulting in that the treated materials do not lose their feel or other desirable properties.
