Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing a spun yarn in which a cocoon yarn is wrapped around the outer periphery of the spun yarn.

[Background of the invention]

The present inventor first attaches cocoon yarn reeled from cocoon balls in a reeling bath to the core yarn which is being falsely twisted and turned by a false twisting means, and produces a cocoon yarn-tangled yarn in which the cocoon yarn is tied around the core yarn. He completed the invention on a method for obtaining the same, and filed a patent application 182290/1986.
56-190582. The application was filed under No. 57-226360. The present invention relates to improvements to these inventions,
When spun yarn is used as the core yarn, there are problems such as yarn breakage even if the direction of false twisting is set to the untwisting direction of the spun yarn. It is possible to obtain cocoon yarn entwined yarn that is tied to the core yarn, and if the false twisting turns are applied to some parts of the kennel, it has better uniformity without protruding fluff or loops than a false twisting spindle. This invention was made based on the discovery that a spun yarn made of cocoon threads can be obtained.

[Purpose of the invention]

The present invention provides a method for producing a cocoon yarn entwined spun yarn with excellent uniformity in which the cocoon yarn is tightly wrapped around the spun yarn and there is almost no protrusion of fluff or the like.

[Structure of the invention]

The present invention provides cocoon yarn tangled spinning, which is characterized in that cocoon yarn reeled from cocoon balls in a reeling bath is combined with spun yarn, and the kennel is twisted in the opposite direction to the twisting direction of the spun yarn to form a section, and then taken off. The present invention relates to a method for manufacturing yarn, and achieves the above object with this configuration.

〔Example〕

The present invention will be explained below using illustrated examples.

FIG. 1 is a schematic side view showing an example of an apparatus for carrying out the method of the invention, and FIG. 2 is a sectional view of a thread obtained by the method of the invention.

In the apparatus shown in FIG. 1, a package of spun yarn 2 is placed below a machine stand 1, the spun yarn 2 pulled out from the package passes through a hole in the machine stand 1, and a size liquid provided on the machine stand 1 is passed through. Application device 3
The only difference from a conventional reeling machine is that the reel is coated with a water-soluble sizing agent and is drawn out above the reeling bath through a vibrator 5 provided through the reeling bath 4. The spun yarn 2 pulled out above the reeling bath is collected like in the case of cocoon yarn! After passing through the V machine 6, it passes through a loop passage formed by an upper drum wheel 7 and a lower drum wheel 8, and at the overlapping part of the loop passage, a kennel twisting part 9 is formed, and the kennel twisting part 9 passes through a guide roller 10 and It passes through the swing roller 1) of the fineness sensor and is wound onto the winding frame 12. In this case, the twisting direction of the kennel twisting section 9 needs to be a direction that imparts rotation in the untwisting direction to the spun yarn 2 from the package. That is, when the spun yarn 2 has a normal Z twist, the kennel twist makes the twist of the part 9 an S twist. If this is made into the same Z twist as spun yarn 2,
The cocoon threads that cling to the spun threads tend to sag or separate.

Spun yarn 2 drawn out above the reeling bath through the vibrator 5
When the cocoon thread 13 reeled from the cocoon balls in the thread handling bath is attached, the cocoon thread 13 and the spun thread 2 are put into the cocoon collector 6, the kennel twisting section 9, the upper and lower drum wheels 7°8, and the kennel again. The twisted part 9 passes through a guide roller 10° and a swing roller 1) before being wound onto a winding frame 12. As a result, the cocoon yarn 13 is tightly wrapped around the spun yarn 2, resulting in a cocoon yarn entwined spun yarn with almost no fuzz or loops, excellent uniformity, and the cross section of which is shown in FIG. be able to.

This effect is due to the fact that the kennel twisting part 9 is different from a false twisting means such as a false twisting spindle, and the kennel twisting part 9 is different from a false twisting means such as a false twisting spindle.
Because there is almost no rubbing effect on the yarn, and because the twisting direction of the kennel twisting section 9 is reversed to the twisting direction of the spun yarn 2, the false twist turning direction is the direction in which the spun yarn 2 is untwisted. The cocoon thread 13 attached to the spun thread 2 in an untwisted state
However, it is thought that the kennel twist is obtained by the twisting of the spun yarn 2 that passes through the section 9 and returns to its original state, so that the yarn tightly clings to the spun yarn 2.

The present invention is not limited to the illustrated example, and even when the spun yarn 2 of the package has been previously applied with a water-soluble sizing agent and is not subjected to the application process of the water-soluble sizing agent by the sizing liquid applying device 3, the spinning The yarn 2 may not be given any water-soluble sizing agent at all, or the spun yarn 2 may be passed through a reeling bath divided into two parts, for example, by a guide or the like from the outside. It may also be directed upwards.

Hereinafter, further specific examples of the present invention will be shown.

Example 1 The apparatus shown in FIG. 1 was used. However, as spun yarn 2, descaling and 7% PVA sizing were performed in advance.
Since the number 40 Z-twist worsted yarn was used, the size liquid applying device 3 was not used. For kennel twisting, part 9 twists are approximately 10 times/c-
The S-twist was used. Spun yarn 2 contains cocoon yarn 1 from 10 cocoon balls.
3 was attached. As a result, compared to the worsted yarn of Spun Yarn 2, a cocoon-bound combed wool yarn was obtained which had a significantly silkier luster and feel, had almost no protrusions such as fuzz or loops, and had extremely excellent uniformity.

Example 2 The same procedure as Example 1 was used except that the spun yarn 2 was a No. 4071 Z-twisted cotton yarn pre-sized with 5% PVA, and the kennel twist was S-twisted at about 15 times/cm in section 9. Cocoon yarn entwined spun yarn was produced under similar conditions. The obtained cocoon thread entangled cotton thread is
Like the cocoon thread-bound entwined combed wool yarn of Example 1, it had excellent uniformity with a silky luster and feel. In addition, if a combed yarn of long fibers with fine fineness such as sea-island cotton is used as the spun yarn 2, or a yarn that has been further mercerized, the luster and texture of the cocoon yarn entwined spun yarn will be further improved. However,
Due to the effect of cocoon thread entanglement, the difference between cocoon thread entanglements appears smaller than the difference between spun yarns.

〔Effect of the invention〕

As described above, according to the method of the present invention, the cocoon threads are tightly wrapped around the outer periphery of the spun thread, and it is possible to obtain a cocoon thread entwined spun thread with extremely excellent uniformity and silky luster and texture. can.
