Abstract

An object of the present invention is to provide a bulky spun yarn with very little twisting torque as a whole. SOLUTION: A core yarn A twisted in one direction and a drafted winding yarn D are twisted in a direction opposite to the core yarn and entangled with the core yarn. The twist torque possessed by the yarn and the twist torque possessed by the wound yarn are opposite to each other, and the twist torques of the two cancel each other, and the overall twist torque is extremely small and bulky. Then, using a ring spinning machine, the supply width between the centers of the core yarn and the wound yarn supplied to the front roller is 1 to 2 mm, and the number of twists of the wound yarn is 35% of the number of twists of the core yarn. ~ 50%.

Description

  The present invention relates to a spun yarn, and more particularly to a spun yarn produced by twisting and interlacing a core yarn and a wound yarn.

When fabrics and knitted fabrics are produced using spun yarns with real twists that have been provided in the past, the twisting torque of the yarns causes twists in the piles of the fabrics, the knit lines of the knitted fabrics skew, and the texture is firm There was a drawback that the product was made.
As measures for improvement, the spun yarn to be used was further subjected to twist-setting heat setting, or two twisted yarns were aligned and twisted in opposite directions to perform twin yarn processing.

However, since the heat setting process and the twin yarn processing are subsequently applied to the manufactured spun yarn, it takes time for manufacturing and is not economical.
In addition, the yarn subjected to the above processing has a problem that the texture becomes stiff.

Furthermore, a spun yarn described in Japanese Utility Model Laid-Open No. 3-30277 is provided as a spun yarn in which the twisting torque of the yarn is balanced.
This spun yarn is a bundle spun yarn that is produced by entanglement of a core fiber twisted in one direction and a staple fiber strongly wound in the opposite direction by air jetting.

  According to the bundling spinning, it is not possible to use a commonly used ring spinning machine, which is not economically advantageous and it is not easy to spin a textured yarn.

  The problem to be solved is that the twisting torque is extremely reduced in the state of a single yarn, and it tries to be bulky and soft.

  The present invention has a core yarn twisted in one direction and a drafted wrapping yarn in order to extremely reduce twisting torque in a single yarn state and make it bulky and soft. The main feature is that twisted in the opposite direction and entangled with the core yarn, the twisting torque of the core yarn and the twisting torque of the wound yarn are in opposite directions, and the twisting torques of the two cancel each other And

The spun yarn of the present invention is entangled by twisting the wound yarn in the opposite direction to the core yarn, so that the twist torque of the core yarn and the twist torque of the wound yarn to be entangled cancel each other. The torque of the whole yarn becomes zero or extremely small.
The spun yarn of the present invention has zero or very little twisting torque, so that no twist or the like occurs in the yarn or fabric (particularly knit fabric).

In addition, when cotton fibers are used as the spun yarn, there is an advantage that a bulky and soft yarn that cannot normally be obtained with cotton fibers can be produced.
Furthermore, ring spinning can be performed simply by installing a device such as a guide and tension in a ring spinning machine that is normally used, and the spinning process can be modified at low cost, and the spun yarn can be provided at low cost. be able to.

FIG. 1 is an explanatory view showing an outline of a method for producing spun yarn. FIG. 2 is a detailed view of the entanglement portion. FIG. 3 shows the appearance of the spun yarn.

  The purpose of making the twisting torque extremely low and making it bulky and soft in the state of a single yarn is to be manufactured at low cost simply by installing a device such as a guide or tension on a normal ring spinning machine.

  FIG. 1 is an explanatory view showing an outline of a method for producing a spun yarn of the present invention, wherein A is a core yarn, and D is a wound yarn. As the core yarn A, a spun yarn that has already been produced by twisting in a certain direction is used. As the winding yarn D, a staple fiber bundle is used.

  The winding thread D pulled out from the shinowaki C has a predetermined thickness by a draft device 5 including a back roller 4, a middle roller 2 having an apron 3, and a front roller 1 set at the top and bottom. Draft up to.

  On the other hand, the core yarn A is drawn out from the wound bobbin B and supplied to the front roller 1 through the tension device 6 through the guides 7 and 8.

The wound yarn D drafted to a predetermined thickness is entangled while twisting the core yarn A at the front roller 1 as shown in the detailed view of the entangled portion in FIG.
At this time, the supply width L of the winding yarn D and the core yarn A is set to 1 to 2 mm. That is, both yarns DA are supplied to the front roller 1 so that the width L between the centers of the wound yarn D and the core yarn A supplied to the front roller 1 is 1 to 2 mm.

The twisting direction of the winding yarn D is opposite to the twisting direction of the core yarn A. Further, the number of twists of the wound yarn D is set to 35% to 50% of the number of twists of the core yarn A.
In the example shown in FIG. 2, the core yarn A is S-twisted, and the twisting direction of the wound yarn D is Z-twisted, but either S or Z twist may be used as the twisting direction. There is no problem as long as the twist direction twisted when the direction and the wound yarn D are entangled is opposite.

  The spun yarn E produced by twisting the winding yarn D around the core yarn A while being twisted is controlled by a snare wire and an anti-node ring belt (not shown), and the rotation speed and weight of the traveler 9 Is twisted and wound on the bobbin while being tension controlled.

  Thus, since the winding yarn D is twisted in the opposite direction to the core yarn A and entangled with the core yarn A, the twisting torque of the core yarn A and the twisting torque of the winding yarn D are opposite to each other. Both twisting torques cancel each other, and the twisting torque can be extremely reduced in a single yarn state, making it bulky and soft.

  The spun yarn of the present invention is a ring spinning process composed of Shinoaki C, draft device 5 and traveler 9, and a yarn supplying device having a tension device 6 and guides 7 and 8 is provided together with the core yarn A as a front roller. By supplying to 1, the ring spinning process that is normally used can be modified at low cost.

  By installing equipment such as guides and tensions on a ring spinning machine that is normally used, the ring spinning process can be modified at low cost, and the twisting torque is extremely low, and the yarn is bulky and soft. Can be provided.
