Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stable non-torque twist yarn without any untwisting torque. That's right.

Peg 7 suspended horizontally in spinner 6 rotating at high speed
A spinner 6 is used for false twisting and untwisting, with the part of the bundled yarn 1 of thermoplastic long fibers continuously transferred to the peg 7 being intertwined, and the side entering the peg 7 being a heat-fixing and twisting zone, and the side exiting the peg 7 being an untwisting zone. The rotation is alternately changed to the opposite rotation after a predetermined period of time, and the bundled yarn 1 is formed with an S real twist part 3, a crimped bulky part 2, a Z real twist part 4, a crimped bulky part 2, and an S real twist part. 3, the crimped bulky portions 2 are interposed between them, and the S real twist portions 3 and the Z real twist portions 4 are alternately arranged and heat-set.

As an example of this manufacturing method, a yarn 1 is continuously transferred to a peg 7 suspended horizontally in a rotating spinner 6.
False twisting machine 8 which twists and untwists the middle part of peg 7 into a heat fixing/twisting zone above peg 7 and an untwisting zone below.
There is a manufacturing method in which the direction of rotation is continuously switched from forward to reverse and then to reverse at predetermined intervals.

This method will be briefly explained as follows.

When the rotation of the spinner 6 is instantaneously reversed, the spinner 6 goes through an operation process of stopping rotation and then rotates in the opposite direction.
The basic idea is that something that has been twisted is then Z-twisted and then untwisted, but when the rotation is instantaneously switched to the opposite direction, S-twist is applied to Z-twist and untwisted. The principle will be broken.

In other words, the basic principle of the false twisting machine 8, in which the balance between twisting and untwisting is maintained and the actual twist is zero, is disrupted.

Therefore, when the rotation of the spinner 6 is switched to the opposite direction, a time lag occurs in the transfer of the yarn 1, resulting in a state in which the twist is not completely untwisted, and this state is
This will remain as the actual twisted portion 3.

Therefore, as shown in the figure, the crimped bulky portion 2, the S real twist portion 3, the crimped bulky portion 2, and the Z real twist portion 4 are repeated in this order.

Therefore, if this switching operation is repeated as needed, the resulting yarn 1 will have a real twisted part, and a crimped bulky woolly part in between, since the yarn 1 is transferred at high speed. This results in a woolly yarn with intervening yarns.

The present invention is a yarn 1 which is heat-set by alternately arranging S real twist parts 3 and Z real twist parts 4 with crimped bulky parts 2 interposed therebetween as described above. However, in the S real twist part 3, a torque is generated that tries to return the twist in the Z twist direction, and in the Z real twist part 4, the twist tends to return to the S twist direction. Since the yarns are arranged alternately, their torques cancel each other out, so that a stable yarn 1 with no torque as a whole can be produced even though actual twist exists.

Furthermore, since the crimped bulky portion 2 is interposed between the S actual twist portion 3 and the Z actual twist portion 4, the canceling effect between the S actual twist portion 3 and the Z actual twist portion 4 is performed in the crimped bulky portion 2. However, this canceling effect is canceled out at the one twisting position, and this further promotes the torque canceling effect between the S real twist part 3 and the Z real twist part 4, so that the entire structure is stable without torque. This means that yarn 1 is obtained.

In addition, S, Z real twist parts 3 and 4 and crimped bulky part 2
When observed, the S and Z real twist portions 3 and 4 become thin because of the twist, and the crimped bulky portion 2 becomes thick.

Therefore, objects made with this thread 1 will have an unusual and interesting texture.

Also, if this thread 1 is dyed evenly, this S, Z
The actual twisted portions 3 and 4 (thin) are denser and therefore appear darker, while the crimped bulkier portion 2 (thick) is coarser and therefore appear lighter, resulting in an even more outstanding design yarn. become.

In addition, the S, Z real twist parts 3 and 4 and the crimped bulky part 2
By changing the degree of twist and the ratio of length and shortness, you can create a variety of excellent design yarns.

In addition, when women's shirts and sweaters are made with this thread 1, the fabric becomes thin and cool, and because of the twist, it becomes a supple jersey-like fabric, which greatly increases the product value. Become.

As described above, according to the present invention, it is possible to provide a stable and innovative non-twist yarn that does not have the torque to untwist it.

Claims (1)

[Claims] 1. The thermoplastic long fiber bundles are continuously transferred to pegs suspended horizontally in a spinner that rotates at high speed, and are intertwined in the middle to create a heat-fixed twisting zone on the side that enters the pegs, and an untwisting zone on the side that exits from the pegs. When performing false twisting and untwisting, the rotation of the spinner is alternately changed to the opposite rotation after a predetermined period of time, so that the bundled yarn has an S real twisted part, a crimped bulky part, a Z real twisted part, a crimped bulky part, and an S real twisted part. A non-torque twist yarn characterized in that S real twist parts and Z real twist parts are alternately arranged and heat-set in the order of the twist parts, with crimped bulky parts interposed therebetween.
