Abstract

PURPOSE:To improve releasability and prevent the frequent occurrence of thread cuts by providing a bunch tail section on a temporarily twisted, crimped thread package used as a warp fabric of a fluid injection type untwisted weaving machine and making the twist releasing direction same as the temporarily twisted direction. CONSTITUTION:A temporarily twisted, crimped thread is a package with a winding width of 8 inches or more and has a bunch tail section, its twist releasing direction is same as the temporarily twisted direction, and the winding density is 0.5g/cm<3> or more. The winding width of the package is the length L between both ends of the thread layer 2. The bunch tail section is a portion B where an initially wound thread Y is wound on the end section of a paper tube 1 several times separately from the normal thread layer 2 when the thread Y is wound on the paper (wood) tube 1 or the like. The twist releasing direction is the twist applied to the thread Y in the direction opposite to the N direction when the thread Y is released in the rotating direction of the arrow N while being withdrawn in the arrow N direction from the releasing side A opposite to the bunch tail section B.

Description

[Detailed description of the invention] 3. Revised light II! Explanation of how to use Ff Wooden cloth is used as a weft during weaving. Traditionally, the packaging form of false-twisted Inaka yarn used for weft during weaving is used for cheese, knee, and paan.

is a typical form, but it is required that the unwinding is smooth (thread breakage, spooling, etc. occur frequently, and the product does not suffer from skin damage). If there is a problem with the winding process, it is recommended to use it after rolling it in a cycle with a relatively good unwinding speed.However, recently, improvements have been made to the winding method, A-ringing, and apricot-gripping. Advances in winding technology, such as higher precision, have made it possible to use false-twisted cheese directly for ¥IG and ¥J11.

In addition, as the speed of false twisting machines has increased, large packages have become available, and packages that used to be 1-2 kg have become larger.

On the other hand, in the recent field of weaving technology, high

It is desirable to use false-twisted processed cheese that is 1-641 in terms of loss.

For this reason, the unwinding properties of the false-twisted 1-crimped yarn boots are improved.
In particular, efforts are being focused on reducing thread breakage.

The problem that the invention attempts to solve
- In the case of Taget room, ■ Ajiera 1 ~ room, the unwinding speed of Yanagito Toshi C is 73400~800u/n1n
Therefore, using the false-twisted crimped yarn cheese manufactured by a very common false-twisting machine as it is for the weft yarn, C is also due to the influence of unwinding property. Or, if the weaving speed increases and the unwinding speed of the weft exceeds 1000+t/+iin, then the weaving speed increases and the unraveling speed of the weft exceeds 1000+t/+iin. When using a terribly common false twist 16, line side 1 yarn booze, 400-= 80C1ig1
In the area of n, thread breakage similar to Lz 4 occurs frequently, and when stable weaving properties are obtained (!ji, n articles (&) are also significantly reduced. This is because the unwinding method jα is 100On# gin
At higher speeds, the ballooning form becomes completely 5"/, and the unwinding tension also becomes weaker, and the relationship between the false twisting direction and the unwinding direction described in 1. This is thought to be because the width of the winding and the density of the trough also result in a small punishment.

This is the case of o□=12 (10+n, '+ain). In the case of Figure 1 (13), the speed of unraveling is too crowded, so the so-called haru-gunnofu! The elephant rises,
As the thread is unraveled, it rolls around and unravels, scratching the surface of the first thread.
The unwinding resistance caused by this is very strong, as shown in Figure 3 (b).

Kibuo Akira has good unwinding performance with no R1 of yarn breakage even in the range of unwinding yarn speed of 1000 + g/INi 10-.
- In 14, we will provide a cheese-shaped false twist 1 and wire side ■ yarn package with a winding width of 81.1 or more that can be continuously operated as a weft for a fluid injection type shuttleless TK machine with a winding width of 81.1 or more. The wire side 1 yarn package is a package in which the valley width of the false twisted wire side -1 yarn is 81.1 or more, and the bunknole part is set in the direction (I, untwisted I).

When winding Y), there is a valley (partial molecule B in which the first yarn (Y) is wound several times around the end of paper tube etc. 1 apart from the normal yarn layer 2).
In addition, in the unwinding direction Ll, the yarn (Y) moves from the unwinding side (^) opposite to the bump 7 round part (8) to the arrow (

If you tie the yarn layer 1 of the next package to be fed to <KJjL bread 1j-ru 6+5 (B)>, the package will be replaced automatically. The winding density 1α ((J/ba) is determined as yarn layer density (wa) per 40 volumes (cIi) of yarn H.

! Ballooning does not occur because the direction of twisting matches the direction of false twisting of the yarn and the winding VPi degree is set to 0.5 (+/- or more J).
At an unwinding speed of i/nin or higher, the yarn to be unraveled becomes tight due to the false twisting torque and unwinding twist, and the valley density is also large. When the thread comes into contact with the surface of the package thread waste, there is less twisting of the next thread layer, so the looseness width of the package (311. is small, and there is extremely little metaplasia due to thread breakage.
! Less than J/”rttj (゛ means that the winding condition is loose, so that the phenomenon of yarn curling on the surface of the yarn 1 during unwinding becomes significant, which is undesirable, and the preferable range of the winding density is 0. .6-0.8g/7 maximum 0.85 (110Vi!

The results are shown in Figure 1 and to the first person. When the unwinding speed is 1i 102 (in/nin), the average level of unwinding tension is Regarding the relationship between the Jj direction and the unraveling direction, although there is no large ff +1 between the Example and the Comparative Example, the variation in Z is much smaller in the Comparative Example, and the difference is 1

Even at the high speed of n, there was a slight thread breakage R1, but there was no significant decrease in the working fh rate and the product quality was good.

Also, even when the unraveling speed is 650n/lN1n, thread breakage is a problem, and the product quality is not as good as the conventional one (Z-8>).
It was good.

Effects of the Invention [The yarn package has the following structure on the false twist winding side of Kokumyo. When unwinding at an unwinding speed of 800 m/+ain or more, which prevents ballooning from occurring, the yarn becomes loose! 5]・
Coupled with the high winding density, the twisting of the next yarn layer is less likely to occur when it comes into contact with the surface of the package yarn layer, and the winding width is Although it is a large package of 8 inches or more, it has excellent unwinding performance, has small tension fluctuations, fewer thread breakages, and has a rotation speed of approximately 45 OR/ii due to the fluid injection type shuttleless a machine.
It is supplied as a weft package for high-speed weaving of n or more (measuring speed: 80011/l1in or more) to prevent yarn breakage, etc.
It is possible to perform continuous operation without running out of the lanol, and it is possible to produce products with a high operating rate of 9 crystals.
