The present invention relates to a yarn having neps formed intermittently in the longitudinal direction of the multifilament yarn. The object of the present invention is to easily obtain a net yarn having a novel design effect formed from a part of the yarn. Conventionally, net yarns such as net yarns and loop yarns made of multifilament yarns are obtained by various methods and are available in large numbers, but in general, they are made using core yarns and wrapped yarns, and are made by twisting machines such as design twisting machines and Italian twisting machines. The wrapped yarn is fed around the core yarn at a speed faster than the core yarn, or is fed intermittently to form a nep, twisted and taken out, and further twisted with a presser yarn to remove the nep. A method is used to obtain net yarn by fixing it. However, since the net yarn obtained by this method is composed of a core yarn, a wrapped yarn, and a presser yarn, it becomes a coarse and hard yarn with a thick fineness. This method requires several types of yarn, a complicated mechanism for intermittent yarn feeding, and a large amount of actual twisting, resulting in low productivity and high costs. In addition, fuzz is generated in the multifilament yarn using a scraper, or after fuzz is generated during drawing and false twisting of undrawn multifilament yarn, the fuzz is entangled in a lump with a fluid jet device or the like. A method of manufacturing net yarn by conjugating it with is also known. However, such a method has the disadvantage that the yarn strength is reduced because the single yarns that become fluff are cut, and furthermore, the neps merely exhibit a lump-like shape, so that only a nep yarn with poor design effect can be obtained. The present invention solves these drawbacks of the prior art,
Another object of the present invention is to provide a net yarn having loop-shaped or snarl-shaped neps formed only from multifilament yarns, which is unprecedented. That is, the present invention provides loop-like nep and snarl-like formations in the longitudinal direction of one multifilament yarn, which are formed by a substantially bundle of all single yarns or a plurality of single yarn groups constituting the yarn. The yarn is characterized in that it has at least one kind of neps intermittently, and each nep is fixed by a knot-shaped part in which the struts at the base end of the neps are entangled to form a strong knot. Next, the nap yarn of the present invention will be explained in detail using illustrated examples. In the yarn of the present invention, all the single yarns or groups of single yarns constituting the yarn 1 are not cut in the longitudinal direction of one multifilament yarn 1, as shown in FIGS. 1 and 2. The nep 2a is bundled and protrudes in a loop shape, and as shown in FIGS. The proximal end side of the nep 2b is twisted into a snarl shape, and the nep 2b appears intermittently at a random frequency. In addition, each nep 2a, 2b... has a strong knot such as a knot shape or a knot-like twisted portion formed by substantially all the single threads of the yarn 1 being bundled or intertwined with each other at the base end of each nep 2a, 2b... It is fixed to the thread 1 by a knot-shaped part 4 which has a shape, and the thread 1
The tension applied to the nep 2 is absorbed by the nodule 4, and
a and 2b cannot be solved. Further, the yarn 1 may have only either the nep 2a or the nep 2b, and furthermore, the yarn may be divided into a plurality of single yarn groups from the knotted part as shown in FIG. Neps 2 have various shapes such as nets with thread groups protruding in a loop shape.
It may exist mixed with a and 2b. In addition, the multifilament yarn is subjected to so-called Taslan processing, which disturbs all the single yarns that make up the yarn.
The processed yarn obtained by opening and intertwining also has loop-shaped parts, but these loops are formed by each single yarn forming a loop by itself, and there is a knot-shaped part at the base end of the loop. Since there is no part, the Neps effect is not strong enough. Therefore, such a yarn is a net yarn of the present invention, that is, a single multifilament yarn, in which all the single yarns or a plurality of single yarn groups constituting the yarn are formed into a substantially bundle shape, such as a loop or a snarl. The thread has intermittently protruding neps, and each nep is a strong knot-like knot-like part formed by substantially all the single threads of the thread being bundled or intertwined with each other at the base end of the thread. This is completely different from net yarn fixed in strips. The net yarn of the present invention as described above has a loop-like or snarl-like shape formed by substantially bundling all the single yarns or a plurality of single yarn groups constituting the yarn in the longitudinal direction of one multifilament yarn. Because it has intermittent neps, when it is processed into a knitted fabric, loop-shaped or snarl-like neps stand out on the surface of the fabric, giving it a much greater surface design effect than simple lumpy neps. Excellent. Moreover, each nep is fixed by a knot-like part in which the threads at the base end of the nep are entangled to form a strong knot, so the tension applied during winding and knitting is absorbed by the knot-like part.
The knot-like part can prevent the neps from unraveling during processing. In addition, since the neps are formed without cutting a single multifilament yarn, the strength of the yarn does not decrease, and since the neps are formed from only one multifilament yarn, they can be used as core yarns. It has a thick fineness and does not become coarse and hard like conventional net yarn that is wound. Next, a method for manufacturing nap yarn will be explained in detail with reference to an example shown in FIGS. 5 and 6. One of the multifilament yarns 1 is fed into the fluid nozzle 7 via the feed roller 5 at a supply speed higher than the take-out speed by the delivery roller 6, and the yarn is introduced from the yarn inlet 8 into the fluid processing section 9 in the fluid nozzle 7. 1, a swirling flow of fluid injected from a fluid inlet 10 connected to a high-pressure fluid supply source to a fluid processing section 9 causes the single yarns of the yarn 1 to be rotated at high speed in a substantially converged state. The yarn 1, which has been given a torque by high-speed rotation, is moved through the fluid processing section 9 toward the outlet 11 at the tip while swirling along the swirling flow of the fluid, and the fluid is removed together with the fluid ejected from the outlet 11. Pull out nozzle 7. Fluid nozzle 7
The thread 1 pulled out is taken out by the delivery roller 6 at a take-out speed lower than the feed speed by the feed roller 5 in a direction different from the fluid ejection direction (in FIG. 5, the direction is approximately 90 degrees different). As shown in Fig. 1, there is a strong knot or knot-like twisted portion formed by substantially all the single threads of the thread 1 being bundled or entangled with each other at the base end in the longitudinal direction of the thread 1. A nep 2 such as a loop-shaped nep 2a having a knot-like nodular part 4 or a snarl-shaped nep 2b
are formed intermittently with a random appearance frequency, and then the yarn 1 is wound under a slight tension by the winding drum 12 having a surface speed intermediate between that of the feed roller 5 and the delivery roller 6 to prevent insufficient binding. In addition to unraveling the nep 2 having the knotted part 4, the yarn has intermittent neps 2a and 2b having the tightly bound knotted part 4, and the shape between the adjacent neps 2 is kept approximately the same as that of the supplied yarn. It is the one that obtains netpuyaan. When the thread 1, which has been rotated by the swirling flow of the fluid in the fluid nozzle 7, is taken out in a direction different from the direction in which the fluid is ejected, the base ends of the thread 1 are entangled in the longitudinal direction, forming a knot-like knot. Although it is not clear why the loop-shaped or snarl-shaped neps 2a and 2b that became the shaped part 4 are formed, it is due to the sudden speed difference when the fluid is drawn out from the fluid nozzle 7 into the atmosphere together with the fluid. Torque due to the swirling motion applied by the fluid processing section 9 is developed and the threads 1 are approximately converged to form loop-shaped or snarl-shaped neps 2a, 2.
b is formed intermittently, and then the ejected fluid acts on the side surface of the yarn 1 which is taken out in a direction different from the direction in which the fluid is ejected, causing each single yarn and nep 2a, 2b to turn in a complicated manner, resulting in the nep 2a, It is presumed that a knot-like part 4 is formed at the base of the thread 2b, such as a knot formed by substantially all the single threads of the yarn 1 or a knot-like twisted part formed by substantially all the single threads being bundled or intertwined with each other. . When producing the net yarn of the present invention, any of thermoplastic synthetic fibers such as polyester and nylon, recycled fibers such as rayon and acetate, and semi-synthetic fibers can be used as the multifilament yarn to be supplied. Further, it may be either a raw yarn such as a drawn yarn or a processed yarn such as a crimped yarn. Further, as for the cross-sectional shape, an irregular (non-circular) cross-sectional shape is preferable than a circular shape in that the nodule-like portions are more tightly formed. In addition, the fluid nozzle used when manufacturing the net yarn of the present invention is a multifilament yarn introduced from the yarn inlet into the fluid treatment section, and is rotated while maintaining a substantially focused state by the swirling flow of fluid injected from the fluid inlet. It is necessary to have both a swirling effect that imparts a swirling effect, and a jetting effect that imparts a complex swirl to each single yarn of the yarn that is taken out from the blow-off port through the fluid treatment section in a direction different from the jetting direction of the fluid, Moreover, it is necessary to balance the turning force and jetting force. For example, if the jetting force is too strong, the loop-shaped or snarl-shaped neps that have been formed are likely to break down, while if the jetting force is too weak, the knots formed at the base of the neps will become insufficiently bound. occurs, so
The balance between turning force and jetting force is extremely important. Therefore, it is necessary to appropriately select the angle of the fluid inlet (β in FIG. 6) and the fluid pressure. A further important point is to use a fluid nozzle with a larger diameter on the yarn outlet side than on the yarn inlet side. In order to form a nep in the yarn, the yarn entrance diameter and yarn exit diameter of the fluid nozzle,
In other words, it is desirable that the ratio to the outlet diameter is 1:3 or more and the thread exit diameter is 3 mm or more, which is larger than a normal fluid nozzle.If this ratio is less than 1:3 or the thread exit diameter is less than 3 mm, the thread This is not preferable because it tends to become smaller and the design effect becomes poor. In addition, in order to form a loop-shaped or snarl-shaped nep with a knotted portion at the base end, it is necessary to take out the multifilament thread in a direction different from the fluid jetting direction. Since the shape and appearance frequency of the nep change depending on the angle (α in FIG. 5) with respect to the take-out direction, various types of nep yarns can be manufactured by changing the angle α. For example, when the fluid nozzle shown in FIG. 6 is used, as the angle α becomes smaller, the neps tend to become larger and the number of neps tends to decrease. moreover,
Although gas, vapor, liquid, etc. can be used as the fluid to be injected into the fluid processing section from the fluid inlet of the fluid nozzle, compressed air is also effective. In addition, the multifilament yarn is fed to the fluid nozzle at a supply speed higher than the take-out speed, but as the overfeed rate between the feed roller and the delivery roller increases, the size of the neps increases, the number of neps increases, and the overfeed further increases. As the overfeed rate is increased, the number of neps does not change, but only the size of the neps tends to increase, and various types of neps yarns can be produced by changing the overfeed rate. As mentioned above, by simply taking out the multifilament threads that are drawn out together with the fluid ejected from the outlet of the fluid nozzle in a direction different from the direction in which the fluid is ejected, the proximal ends of the threads become entangled in the longitudinal direction, forming a knot-shaped part. Because it is possible to obtain a net yarn having intermittent loop-shaped or snarl-shaped nets, the nets do not come undone during processing, and when processed into woven or knitted fabrics, the neps do not stand out on the surface of the fabric. Net yarn with excellent surface design effects can be easily manufactured using only fluid nozzle processing, and it is also possible to change the ratio of the supply speed to the fluid nozzle and the take-out speed, or to change the direction of the fluid jet and the take-out direction of the multifilament yarn. By changing the angle formed by the nets, it is possible to easily produce net yarns with different sizes and frequencies of appearance of the nets. Furthermore, since only one supply thread is required, the space required for the creel stand is smaller than in the case where two or more supply threads are used, and there is an advantage that production efficiency is improved. The present invention will be specifically explained below using examples. Examples 1 to 5 The fluid nozzle shown in FIG. 6 is provided between the feed roller and the delivery roller as shown in FIG. Nep yarn was manufactured by changing the angle α formed by the air pressure and the air pressure. Table 1 shows the manufacturing conditions and the properties of the net yarn obtained. The obtained net yarn has loop-shaped or snarl-shaped neps intermittently in the longitudinal direction of the yarn, each of which has a protruding length of 2 to 9 times the yarn diameter, and each nep has a nodular part at the base end. It has a novel design effect in which the angle α is firmly fixed, and as the angle α becomes smaller, the nep tends to become larger and the number thereof tends to decrease.
