Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a bulky blended yarn of natural fibers and synthetic fibers that has elasticity and transforms into a yarn that shrinks when immersed in hot water that can be used for ordinary weaving and knitting. and its manufacturing method.

[Conventional technology]

Conventionally, it has not been possible to impart elasticity to blended yarns of natural fibers and synthetic fibers.

In particular, it has been considered impossible to latent shrinkage torque and impart elasticity to blended yarns or intertwisted yarns of synthetic fibers and natural fibers, which have excellent properties as synthetic fibers.

A product called spantex, which is a covering made from a special synthetic fiber, has been developed, but it is not widely used because it is expensive, has poor heat resistance, and has problems with superimposed color.

[Problem to be solved by the invention]

The present invention uses synthetic fibers such as cheap and durable Tetoron (polyester yarn synthetic fiber), which has excellent heat resistance and dyeability, does not hinder weaving or knitting, and is resistant to wrinkles and has a texture. The object of the present invention is to provide a bulky blended yarn of natural fibers and synthetic fibers having stretchability that can be used to weave and knit woven or knitted fabrics having good stretchability, and a manufacturing method that can economically mass-produce the products.

[Means to solve the problem]

The details are as follows with reference to the accompanying drawings.

A yarn consisting of two or more blended yarns of natural fibers and synthetic fibers, characterized in that the yarns have approximately the same diameter and are curled into an average coiled state, and have elastic properties such as natural fibers and synthetic fibers. This relates to a bulky blended yarn of fibers.

The blended yarn of natural fibers and synthetic fibers, which is continuously fed by sliding it on a yarn feeding roll, is heated and untwisted through the spinner 19 of the rotating spinner unit 3, and then wound onto the winding cylinder 4. At the time of heating, far-infrared rays are irradiated on the heating zone side to heat the treated system 1゛, and this rolled-up treatment system 1゛ is subjected to a gluing treatment and then rewound, or the treated system 1゛ is subjected to a gluing treatment when it is wound up. The present invention relates to a method for producing a bulky blended yarn of natural fibers and synthetic fibers having stretchability, which is characterized by holding the yarn in an unshrinkable yarn and shrinking it into a coiled state by blanching.

[Effect]

To explain based on an example, the fed yarn 1 passing through the spinner 3 has a heating zone below and an untwisting zone above the spinner 3 as a boundary.

If the heating device C is placed on the side of this heating zone, the following operations will be performed continuously: heating while heating in the S direction and untwisting in the Z direction.

Since this treatment system heats the synthetic fibers on the heating zone side, a shrinkage torque that tends to cause the synthetic fibers to shrink becomes latent.

The reason for this is basically that it is heated in the heating zone, but when feeding the yarn, the fuzz of the natural fiber itself and the fuzz of the blended yarn are removed by sliding it on the yarn feeding roll, and the fuzz is smooth. The molecular structure of synthetic fibers is changed by instantaneously heating and untwisting the yarn by minimizing the resistance to the spinner, and by heating it with far infrared rays, which allows the far infrared rays to pass through to the core of the synthetic fibers. It instantaneously heats the inside of the fiber while it is still heated, uses the thermoplasticity of the synthetic fiber to maintain the heated state for an instant, and immediately untwists and air cools it, creating a strong latent shrinkage torque. .

By sizing the modified yarn and then winding it up or directly sizing it and winding it up, a normal, smooth, non-shrinkable treated system 1° is obtained, which can be provided, for example, as a normal warp yarn. Since this warp is a normal smooth blended yarn, it is a yarn that can be easily woven and knitted into fabrics for various purposes using looms and knitting machines.

Then, when the fabric is blanched in hot water at about 80℃, the glue is removed and the natural fiber becomes softer, so the latent shrinkage torque of the natural fiber itself and the stronger latent shrinkage torque of the thermoplastic synthetic fiber. As a result, the treatment system 1 of the present invention tends to curl into a large coiled state and shrinks, resulting in, for example, cloth having elasticity.

At this time, if the blended yarn is a single yarn, when it is blanched, the curl condition will often not be uniform due to uneven blending of the blended yarn or unevenness in the thickness of the yarn, but if two or more blended yarns are pulled together or twisted together, When a yarn with a 30% diameter is used, unevenness in blending and unevenness in thickness cancel each other out, resulting in a bulky blended yarn of natural fibers and synthetic fibers that is shrunk into a good coiled state with approximately the same diameter and average curl.

In this case, twisted yarns do not shrink individually when contracted into a coiled state, so they form a better coiled state than aligned threads.

〔Example〕

The false twisting device of the present invention includes a yarn feeding device a provided with a yarn feeding bobbin;
Yarn feeding device A is provided above the feeding device A, in which the feeding yarn is wound in parallel and is combined with a drive roll and a guide roll. Heating device C that heats by irradiating far infrared rays, and Heating device C
A spinner device d which is a combination of a rotatably driven spinner in which a roller-shaped spinner is rotatably mounted above the spinner, a spindle and a drive belt, and a winding cylinder having a winding cylinder provided above the spinner. It consists of a device e.

Although the yarn feeding device a in the drawings shows a case where the yarn feeding bobbin 2 is installed horizontally, it may be installed vertically.

As natural fibers, all natural fibers can be used, such as cotton, silk, hemp, and Otsuna, which are similar to natural fibers.

Various synthetic fibers such as polyester, nylon, and acrylic are used.

Figure 15 shows the yarn of the present invention, which is made from a single yarn blended with natural fibers and synthetic fibers. By making it irregular, coils of various sizes can be created, and this irregular change can also be used conversely.

FIG. 13 shows a yarn of the present invention made from a blended twin yarn.

In the figure, 8 is a tension adjustment device, 11 is a bolt, and 1 is a tension adjusting device.
3 is a spring, 14 and 14' are polymerization plates, and mo is a thread guide.

The water conveying device shown in the drawing has a small-diameter ceramic fixed guide roll 6' and a large-diameter drive roll 6 arranged side by side, and feeds the yarn from the guide roll to the fixed guide roll 6'. By detouring and rubbing, air is expelled from the natural fiber core and the heating effect is improved.

Also, a seesaw frame 42 attached to the support shaft 41
A gear shaft 43 is provided at one end, a driven gear I is provided on this gear shaft 43, and a driving gear 6 is meshed with this driven gear shaft. The figure shows a case in which rotational power is transmitted to the drive roll 6 provided at the drive roll 49, and the seesaw frame 42 is caused to see-saw, thereby separating the driven gear U from the drive gear 6 and cutting off the power transmission.

A small-diameter fixed guide roll 6' is provided protruding from the side wall of the water tank d, which is required when a wet method is adopted, and thread section flanges 51 are installed in parallel, and the drive roll 6 is also provided with yarn section flanges 52 in parallel. However,
The initial spacing between the tsuba is made wide because there is no twisting.

The reference symbol in the figure is a fixed guide auxiliary roll on the drawer side.

Furthermore, it is efficient to provide a heater 39 in the water tank field and impregnate it with heated water.

Furthermore, if a tension adjustment device 8 with a buffering effect is provided, yarn breakage can be prevented.The upper spinner unit 3 is disposed above and below, and a single spinner unit 3 is sufficient without providing a heating device C between them. Since it exerts a buffering effect so that a constant tension is always applied, a good product that shrinks uniformly without yarn breakage can be obtained.

In addition, the twisting between the upper spinner unit 3 and the lower spinner unit 3 is not untwisted, and the twisting is stopped while remaining in the heating zone, and the twisting is only performed after passing through the upper spinner unit 3.

Various structures can be adopted for the heating device C in the drawing, but it is preferable to use an electromagnetic wave heater of the type in which a heater n that generates far infrared rays is built into the tube wall, and the yarn feeder 1 passes through the center of the tube. A method of passing the yarn supply l in contact with a far-infrared heater may also be used.

As shown in Figure 2, an oil heating tube 2 is provided inside the case, oil heated to a constant temperature is passed through this heating tube 2, and the yarn feeding tube 1 is brought into contact with this oil heating tube 2. In that case, heating management at a constant temperature becomes easier than when using an electric heat source.

In this case, the oil heating cylinder 6 may be bent to ensure contact with the yarn feeder 1.

As shown in FIG. 4, the spinner device d in the drawing has a spinner integrated 3 by providing a bearing cylinder on the upper part of the spindle, which rotates at high speed while being supported by a holding cylinder 31 with a bearing inside, and which is supported by a holding cylinder 31 containing a bearing. Form the bearing tube into this bearing tube.
The ends are set upright facing each other, and the Tsuzumi-shaped prefectural fee recess 1'
A spinner 19 having a spinner 19 is rotatably mounted via a bearing (to avoid making noise and to ensure smooth rotation), and the yarn 1 is wound around the prefecture recess η of the spinner 19 above the center of the spindle. The spindle 10 is eccentrically set so that
・The 1σ structure prevents thread breakage of weak natural fibers and reduces needle thread runout.

The lower the resistance of the spinner ratio, the higher the rotation.
Can be produced efficiently.

The winding device e in the drawing consists of a winding cylinder 4, its Surf Ace roller, a winding roller, and its Surf Ace roller 5, and is capable of increasing or decreasing the rotational speed of the winding roller or the driving speed of the belt. If the number of rotations of the spindle 4 is adjusted to increase or decrease, the degree of heating and untwisting by the spinner unit 3 will differ, and as a result, the degree of shrinkage can also be varied.

If the feeding yarn 1 is thick, it is strong, and if it is thin, the resistance is low, so a dry method without adding water to the water tank d is fine, but if it is medium-thin, the resistance is large and the thread breaks easily, so add water to the water tank. A wet method, in which the material is poured and heated with water, is preferable because fluffing can be done better.

In the figure, the sign stop is ceramic, n is the dora pass guide, n is the heat insulating part, (capital) is the sharp part of the spindle at 10/10 degrees, U is the concealing tube, and a and opening are the two single threads of the material. It is.

〔Effect of the invention〕

The present invention is a yarn consisting of two or more blended yarns of natural fibers and synthetic fibers, which is a normal smooth yarn that can be woven and knitted, and when blanched, it becomes a coiled yarn due to the latent contractile torque. It curls and contracts, creating an elastic yarn with unprecedented bulk.

In particular, blended yarns that use two or more material yarns cancel out the shrinkage unevenness caused by uneven blending and thinness of the single material yarns, resulting in extremely good bulky shrinkable yarns that curl to approximately the same diameter and averagely. .

Products woven or knitted as ordinary threads through sizing process are transformed into stretchable products by blanching, which can be used for various clothing, sportswear, and underwear.

This is a long-awaited elastic yarn that can be used in a variety of ways, including socks.

In particular, since the main material is synthetic fiber, it is durable, wrinkle-resistant, heat resistant, and has excellent dyeability.The material is spun yarn, and it is also blended with natural fibers, so it has an excellent texture.
It also has excellent water absorption properties, making it a product that is extremely comfortable to wear and wear, demonstrating excellent practicality.
