DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing special curled yarn, and more specifically, to a method of manufacturing a special curled yarn, in particular, a method of manufacturing a thermoplastic synthetic filament yarn in a fixed manner.
The present invention relates to a method for producing special curled yarn using a temporary twisting process in which the yarn is tied and run more than once. Conventionally, as one of high-speed temporary twisting means, a temporary twisting method has been proposed in Japanese Patent Publication No. 50-29061, etc., in which yarn is wound around a pin to perform temporary twisting. This processing method does not require a drive unit to insert temporary twists, and the number of insert twists does not depend on speed.
This is an extremely advantageous processing method for high-speed processing. However, there is a limit to the number of twists inserted in the direction opposite to the original twist direction of the yarn, and the resulting curled yarn is more There were problems such as lack of bulk and low residual torque. Therefore, when it is necessary to insert the number of twists in the opposite direction to the original twist direction, a method is used in which the original twist direction of the yarn is inserted in the opposite direction in the spinning process or in a yarn machine, etc. to obtain curled yarn in the opposite direction. Ta. However, the process of changing the original twist direction of the yarn and adjusting the original twist direction and the insertion twist direction during temporary twist processing can easily lead to decreased work efficiency and mistakes, which can lead to high manufacturing costs or a huge hindrance to new product development. I'm getting old. The present invention aims to solve the above problems and consists of the following configuration. That is, in the twisting type temporary twisting process in which the synthetic fiber filament yarn is tied to a fixing pin one or more times and run, the single fiber denier is set to 2.0 denier or less, and the additional twist is inserted in the opposite direction to the original twist direction of the yarn. It is something. The present invention will be explained in more detail with reference to the drawings. FIG. 1 is an example of an embodiment of the present invention. Reference numeral 1 denotes a synthetic fiber filament yarn, which is fed from a feed roller 2 to a shrinking processing area. 3 is a hot plate, which heat-sets the temporary twist imparted to the yarn. Reference numeral 4 denotes a twisting device having a fixing pin, which threads the thread as shown in FIG. 2, and in this thread threading, a temporary twist is given to the incoming thread by twisting the thread. The yarn is sent out by a delivery roller 5 and wound up by a winding device 6. What is particularly important in the present invention is that the filament yarn has a single fiber denier of 2.0 denier or less, and by inserting a supplementary twist in a direction opposite to the original twist direction, the residual torque in the opposite direction to the original twist direction can be reduced. The advantage is that it is possible to obtain a yarn having a special crimp and bulkiness. Here, the synthetic fiber filament yarn used in the present invention is a drawn yarn, semi-drawn yarn, or undrawn yarn such as polyester or polyamide yarn, and the finer the denier of the single fiber filament yarn, the more suitable it is. As shown in , the difference ratio of the number of insertion twists between the single fiber denier d and the number of insertion twists in the same direction as the original twist direction of the filament yarn (T 1 ) and the number of insertion twists in the opposite direction (T 2 ) from the original twist direction. r(=T 1 −T 2 /
T 1 ×100), as d becomes smaller, r
It was found that the size of the curve is generally smaller. In other words, the number of insertion twists in the direction opposite to the original twist direction increases. The specific range of d is preferably 2.0 denier or less, taking into account the physical properties of the yarn. However, if it is less than 1.0 denier, fluffing or single yarn breakage will easily occur during temporary twisting, so 1.0 to 2.0 denier is practically preferable.
On the other hand, if the denier is larger than 2.0, the difference in the number of insertion twists will increase, so the level of shrinkage characteristics will differ. The tendency shown in FIG. 3 is a peculiar phenomenon in which the thinness of the denier of the single fiber filament yarn greatly influences the insertion twist number difference ratio, and the total denier of the filament yarn has no relation at all. Regarding the surface characteristics of filament yarn, the cross-sectional shape does not have a particular effect, but yarn-to-yarn frictional resistance tends to be involved in the twisting type temporary twisting method, so it is necessary to appropriately select a type with relatively high resistance. It is essential to use it. Regarding the original twist number, it is a sweet twist that is more than maintaining convergence, for example 20 ~
If it exceeds 30 T/m, the effect of the present invention will be reduced, which is not preferable. As mentioned above, the winding direction is opposite to the original twist direction of the filament yarn, but needless to say, it is the same direction. Regarding the processing conditions, it is preferable that the tension is higher as long as it does not affect the generation of fuzz or operability, and the setting temperature is higher than the normal temporary twisting temperature because this will reduce the insertion twisting number ratio r. range. As described above, in the twisting type temporary twisting method of the present invention, it is possible to insert the additional twist in the direction opposite to the original twisting direction of the yarn because the screw elasticity of the single fiber becomes smaller and the actual twisting density is reduced. It can be understood that as the value becomes higher, the effect of the original twist number is small. Regarding the physical properties of the yarn obtained by the present invention, it is possible to obtain characteristic values of elasticity recovery rate and residual torque that are almost the same as those of the yarn that is curled and twisted in the same direction as the original direction of the yarn. This development can be applied to mixed knitting using SZ yarns, fabrics using SZ yarns, etc. Next, regarding the effects of the present invention, S and Z addition processing can be carried out regardless of the original twist direction of the yarn, so it is possible to solve twisting mistakes and eliminate the reverse original twisting process, etc. It leads to sexual improvement. The present invention will be explained in more detail with reference to Examples. Example 50 denier polyester filament yarn, 36
The filament, that is, the single fiber denier was 1.39 denier, and the original twist number was 12 T/m in the S direction, and a temporary twisting process was performed using a twist matching method. Heat set temperature 220
℃, the yarn speed was 700 m/min, and the processing tension was 5 g, and the directions from the insertion point were S and Z, respectively. For comparison, a temporary twisting process was performed using the same material with a 50 denier, 18 filament, that is, a single fiber denier of 2.78 denier, and an original twist number of 13 T/m in the S direction.
As a result, as shown in the following table, the number of insertion twists of the present invention is almost the same for both S and Z, and a special curled yarn with virtually no difference in elasticity can be obtained in terms of yarn physical properties. I was able to do that. 【table】
