Description

    TECHNICAL FIELD The present invention relates to a card for spinning wool for uniformly dispersing and mixing two or more kinds of hair fibers in wool spinning, and a method for producing a heterogeneously dispersed mixed spun yarn. As a specific example, a card for wool spinning suitable for producing a woolen yarn having a marbled color pattern or a mottled pattern by dispersing and mixing two or more colored hair fibers in a non-uniform manner. An example is a method for producing a marbled yarn that is non-uniformly dispersed and mixed. In particular, it can be preferably used in spinning yarn spinning.

    In the following description, the “first fiber” is the fiber that is fed into the wool spinning card after finishing the preparation of the raw hair, and the “second fiber” is not completely dispersed in the first fiber. A fiber that is mixed evenly. The fiber constituting the “second fiber” is not limited to one type, and may be a plurality of types. Further, a plurality of “second fibers” may be mixed with each other being non-uniform.

  Wool spinning can be roughly divided into wool spinning and worsted spinning. Recently, there is a tendency that the technical difference between wool spinning and worsted spinning tends to be small. However, all conventional wool spinnings are made by uniformly dispersing and mixing several kinds of raw wool. However, in order to obtain a high-value-added fabric having a special color pattern, a part of “Shino” made of the second fiber dyed in advance in the first fiber carding, pre-spinning process, etc. (Shino) "(also referred to as a sliver) was added to disperse the fibers in a non-uniform manner and mixed to produce a kind of woolen spun yarn that was marbling and colored. This marbled yarn has two or more colored wool fibers, that is, the first fiber and the second fiber are non-uniformly dispersed and mixed to form a marbled pattern or a mottled pattern. The finished fabric had a unique appearance and was fashionable.

  Prior to describing the present invention, in order to facilitate understanding of the present invention, the card process will be briefly described with reference to the drawings, centering on the example of spun spinning conventionally used in the production of marbled yarn. Let me explain. 2 and 3 are side view illustrations showing a card process composed of three piles of spun spinning. The carding process is usually a woolen card in which 2 to 4 piles are connected in series to form a uniform thin film web by unwinding the raw hair 21 and defibrillating, removing and mixing the raw hair. (Roller card) part 22 and a capacitor part 23 for dividing the web into narrow “sino”.

  In general, the connected first card is a breaker card or scripter card 24, the intermediate card is an intermediate card or intercard 25, the final card is a finisher card 26, and the fourth card is the third card. Is called the finisher first card, and the 4th mountain is called the finisher second card. These cards are constituted by a large number of rollers wound with a needle cloth whose needle tip is inclined in either the direction of rotation of the roller or the direction of rotation of the roller, or upright. The needle is bent in the middle part in the shape of "<", or the straight one is used. Further, an intermediate hair supply portion 27 is provided between the cards so as to correct unevenness of the web taken out from the previous mountain and supply hair to the next mountain.

  Normally, the raw hair fed from the automatic raw material feeding device 28 of the hair feeding unit falls on the feed lattice 29 every fixed amount, and further sent to the breast card 31 by the feed roller 30 for preliminary opening. The pre-opened fibers move onto the cylinder 1 of the next breaker card 24, and the fibers are mixed while being opened one by one. Hereinafter, several walker (worker) 2 is arranged on the circumference of each cylinder 1 of each card 24, 25, and 26, and a part of fibers are combed from the needle tip 4 of each cylinder to move to walker 2. And carding action. Further, a stripper 8 having a small diameter is disposed as a roller for taking away the fibers transferred to the walker 2 and transferring them to the cylinder 1. The fibers on the circumference of the cylinder are once transferred to the doffer 32 and spun. A deck roller 33 for finally removing seeds and the like is attached to the doffer 32 of the finisher card 26.

  In order to easily perform the above action, the walker is mounted so that the rotation direction is opposite to that of the cylinder and the tip of the needle is inclined in the same direction as the rotation direction, and the surface speed is considerably reduced than the surface speed of the cylinder. And operate. In addition, the stripper is mounted with the rotation direction in the same direction as the walker, that is, in the direction opposite to the rotation direction of the cylinder, with the tip of the needle inclined in the rotation direction, and the surface speed is set higher than the surface speed of the walker. It is in operation. The rotation direction of the deck roller is opposite to that of the doffer, and the needle tip is tilted in the opposite direction of the rotation direction like the doffer.

  By the way, in the conventional marbling yarn, the above-mentioned spun card is left as it is, and as shown in FIG. 4, a “sino” feed portion 34 is attached to the deck roller 33, and on the first fiber on the periphery of the doffer. The “shino” made of the second fibers dyed in a different color is supplied through the horizontal swing guide 35 and the feed roller 36 and is non-uniformly distributed. The reason why the roller was supplied on the periphery of the deck roller was mainly because the supply device was easy to attach and the operation was simplified.

    In the above-described conventional method of producing a marbled yarn, it is only necessary to supply the “shino” made of the second fiber using the card for spinning wool as it is, and to switch to the production of the marbled yarn which is a special yarn at any time. It was easy to use and was used for a while. However, recently, when marbled wool spun yarn has been reviewed, the conventional method cannot be used to freely adjust the size and length of the marbled pattern because the fiber length of the second fiber is disjoint. As a result, there has been a restriction on the product that the desired marbling pattern cannot be given arbitrarily. Further, the card also has problems such that the second fiber supplied on the deck roller is difficult to ride on the first fiber, and there are many yarn breaks. However, on the other hand, the demand for specially-marbled yarn has not reached the level that requires a dedicated line, so you must basically use the conventional production line for regular yarn, and use regular yarn in a timely manner. There is a situation that it is necessary to switch to the production of marbling yarn or to return to the original state to produce normal yarn. The present invention has been completed as a result of repeating research and trial and error in order to solve the above problems.

    As a result of studying the above problems, for example, the marbling pattern of the fabric is adjusted so that the second fibers are adjusted to the required length and the mixing ratio is adjusted according to the required pattern, and the first fibers are preferably used in the finisher card 26. It was found that it should be mixed into No. 10. Furthermore, the present inventors have reached the present invention by researching specific means and repeating trial and error. In other words, the wool spinning card according to the present invention tilts the needle tips 4 of one or more walker 3 (hereinafter referred to as “feed walker”) of the walker 2 disposed on the cylinder 1 in the rotational direction and feeds the card. The walker 3 includes a lateral guide 6 and a feed roller 7 for supplying “sino” 5 made of the second fiber to the feed walker 3, a supply speed of “shino” 5 and a take-up speed of the feed walker 3. A feed speed controller for the feed roller 7 and / or a rotation controller for the feed walker 3 for adjusting the speed difference is attached, and the speed difference is adjusted to form the second “Shino” 5. It is characterized by having a mechanism for shifting the fibers to the feed walker 3 while cutting the fibers to a required length.

    According to the present invention, it is possible to produce a wool spun yarn in which the length of the second fiber mixed with the first fiber is adjusted to an appropriate length. For example, the size and length of the marbled yarn pattern can be easily adjusted to the required one. Further, the second fiber is not lifted on the feed walker, and the first fiber is suppressed toward the middle of the needle, thereby preventing the occurrence of thread breakage or macro-pattern unevenness. In addition, it is easy to switch between production of normal yarn and marbling yarn.

    The mode of operation of the wool spinning card according to the present invention will be described with reference to the drawings. In the carding process, the first fibers on the cylinder that have been repeatedly carded between the cylinder and each walker are scraped by the feed walker and transferred onto the feed walker. “Shino” made of one of the second fibers is taken up by the feed roller while the width of the web made of the first fiber is swung from side to side by the sideways guide. Further, from the feed roller, the needle tip is transferred to the feed walker inclined in the rotation direction, and is superposed on the first fiber transferred from the cylinder to the feed walker. In the present invention, the stylus tip of the walker, which has been tilted in the direction opposite to the rotation direction in the past, is tilted in the rotation direction as shown in FIG. The second fiber that has been drawn is caught by the needle tip of the feed walker and sunk toward the middle of the needle. Therefore, even if the second fiber is on the first fiber that has been transferred from the cylinder to the feed walker, the second fiber is firmly held by the needle without floating.

  Then, since the needle speeds up with the rotation of the feed walker and moves away from the feed roller, the second fiber is cut at a point having a substantially constant length, which is not balanced with the feed speed of the feed roller. On the other hand, in the conventional method, “Shino” is supplied to the deck roller whose needle tip is inclined in the direction opposite to the rotation direction. It is considered that the first fiber is put on the roller while floating on the roller, and the cutting point is loosened and the cutting fiber length is varied as a result.

  On the other hand, changing the direction of rotation of the deck roller and the direction of the needle point is not feasible due to its action and effect. Since the feed walker has a small diameter and can be easily exchanged, it is recommended to prepare a new one or, if possible, install it with the left and right sides reversed and reverse the direction of the needle tip. Further, the carding action is not lost even in the feed walker, and since 4 to 6 walkers are attached per cylinder, there is no great variation in the card performance.

  Since the adjustment of the fiber length of the second fiber is determined by the difference between the feed speed of the second fiber from the feed roller and the take-up speed of the feed walker, the feed speed of the feed roller and / or the rotation speed of the feed walker (surface By changing the speed). When the supply amount from the feed roller is constant, the fiber length is shortened if the rotation speed of the feed walker is increased, and the fiber length is increased if the rotation speed is decreased, so that it can be easily adjusted to the required length. Further, by configuring the rotation speed of the feed roller to be variable, the mixing ratio of the second fiber can be increased or decreased, or the fiber length can be easily adjusted. These adjustment conditions vary depending on the second fiber supply amount, fiber length, fiber type, and the like, and can be determined by prior trials and experiences. Adjustment of the rotation speed of the feed roller or feed walker can be easily performed by using, for example, an inverter.

  Further, preferably, for the purpose of facilitating the mixing of the second fiber, the stripper corresponding to the feed walker is configured so that the rotation speed can be variably controlled, and in the direction opposite to the rotation direction of the feed walker, that is, the conventional stripper The fiber on the feed walker is transferred to the cylinder by decelerating and rotating in the direction opposite to the rotation direction, and tilting the needle tip in the direction opposite to the rotation direction. At that time, depending on the conditions, the stripper is caused to freely rotate with the feed walker, or the fibers are moved onto the cylinder so as to be sandwiched between the stripper and the feed walker.

  The setting position of the feed walker is appropriately set according to the purpose so that the dispersion and mixing of the first fiber and the second fiber do not proceed excessively and the effect of non-uniform dispersion necessary for producing the required effect does not disappear. Determine. In general, the finisher card walker, in particular, the second to fourth counting from the final walker, is preferred.

    The method for producing a card for wool spinning and a non-uniformly dispersed mixed spun yarn according to the present invention is suitable for producing a marbled yarn in which fibers of two or more colors are non-uniformly dispersed and mixed. By using a nep yarn for all or part of the second fibers, a wool spun yarn having a unique pattern can be obtained, and a very fashionable fabric can be woven or knitted using the wool spun yarn. In addition to the above, the present invention is expected to realize wool spun yarn having new characteristics and texture, or a new fabric using the same, by unevenly dispersing two or more kinds of fibers having different characteristics.
