The core yarn 11 is formed of white filament yarn which is not colored. The first floating yarn 12, the second floating yarn 13 and the third floating yarn 14 are formed by the dyed yarn formed by coloring the filament yarn at the raw yarn stage, and each of them has a red color so as to have a different color tone. It is colored yellow and blue. The first floating yarn 12, the second floating yarn 13, and the third floating yarn 14 are entwined with the core yarn 11 by being subjected to the mixed fiber treatment.

The non-slab portion 16 of the air slab yarn is the core yarn 1
1, the first float 12, the second float 13 and the third float 1
4 is similarly formed by being entangled. In the non-slab portion 16, a color tone in which red, yellow, and blue, which are colored in each floating yarn, are appropriately mixed is developed. On the other hand, the slab portion 15 of the air slab yarn is different from the core yarn 11 in that the first floating yarn 12, the second floating yarn 13, and the third floating yarn
The floats 14 are randomly entangled and the first floats 1

In the slab portion 15, the color tone of the yarn entwined with high density is deeply expressed. For example, in FIG.
The slab portion 15 located at the left end has a red color tone because the yarn entwined with high density is the first floating yarn 12. Further, the slab portion 15 located in the middle portion has a yellow color tone because the yarn entwined with high density is the second floating yarn 13.
Further, the slab portion 15 at the right end has a blue color tone because the yarn entwined with high density is the third floating yarn 14.

Since the first floating yarn 12, the second floating yarn 13 and the third floating yarn 14 are entwined with the core yarn 11 at random in terms of length and density, each slab portion 15
The color tone developed in each of the and non-slab portions 16 is random throughout the yarn.

The above-mentioned slab portion 15 and non-slab portion 1
Many 6 are randomly formed in the running direction of the yarn in terms of length and number. Therefore, by randomly mixing the slab portion 15 and the non-slab portion 16 having random color tones, a complicated color tone is expressed in the entire yarn, and a novel color tone is produced. Further, the first floating yarn 12 and the second floating yarn 1 are entwined with the core yarn 11 by being mixed with air.
The filaments forming the third and third floating yarns 14 respectively generate loops, spiral coils, and the like. These loops, spiral coils and the like are three-dimensionally developed around the yarn around 360 °, and the air slab yarn is bulky and has a soft feel and a bulge.

In front of the mixed fiber nozzle 22, the core yarn 11 is joined with the second floating yarn 13 in the over-fed state, and the first floating yarn 12 and the third floating yarn 14 in the non-over-fed state. In the mixed fiber nozzle 22, the second floating yarn 13 in the over-fed state is supplied more than the first floating yarn 12 and the third floating yarn 14 with respect to the core yarn 11 per unit length. The mixed fiber is processed to form the mixed fiber 17.

In the slab portion 15 of the air slab yarn, the second floating yarn 13 is the core yarn 11 by the amount that is excessively supplied during the fiber mixing process.
It is formed by being entangled with a thick and high density. In this state, a large number of loops, spiral coils, etc. are formed at high density by the filaments forming the second floating yarn 13, and these swell and spread on the yarn surface, whereby the first floating yarn 12 and the third floating yarn 14 are formed. As a result of being covered, the color tone of the second floating yarn 13 is deeply expressed in the slab portion 15.

The non-slab portion 16 of the air slab yarn has a first float 12, such as when switching the overfed yarn from the second float 13 to another float.
All of the second floating yarn 13 and the third floating yarn 14 are formed by being mixed and processed without being over-fed. In this state, the first floating yarn 12, the second floating yarn 13 and the third floating yarn 14 are also entangled with the core yarn 11 in the same manner, and the filaments forming each of them are mixed while forming a loop, a spiral coil or the like.

A variety of color tones are developed by changing the yarns that are entangled with high density in each slab portion 15 on the yarn. Further, each of the first floating yarn 12, the second floating yarn 13 and the third floating yarn 14 three-dimensionally generates fine loops, spiral coils, etc. during the fiber mixing process. Therefore, while the loop formed on the yarn surface, the spiral coil, and the like are bulky and have a soft feel, the slab portions 15 and the slab portion 15 and the non-slab portion 16 have various color shades. It can bring out a new color.

Also, this air slab yarn is core yarn 11

The air slab yarn of the second embodiment uses filament yarns made of different kinds of materials for the first floating yarn 12, the second floating yarn 13, and the third floating yarn 14, and as a result, each material is used for each slab portion 15. The property based on the property of is emphasized and expressed. For example, acetate type, rayon type,
When each of the polyester cation type filament yarns is used and the air slab yarn is dyed with the polyester cation type dye, only the polyester cation type filament yarn can be dyed. And since elasticity, flexibility, etc. are different for each type of material,
It is possible to obtain an air slab yarn having a novel texture such that the touch feeling is different for each touched portion.

Further, as a result of false twisting,
The air slab yarn will be rubbed over the entire yarn, increasing the soft feel. In addition, the loops, coils, etc. are cut and fluff 1
By forming No. 8, high bulkiness is further improved. Also, by cutting most of the loops, coils, etc., the fluff 18 is formed in the loop formed by the loops and the spiral coil.
It is possible to prevent the phenomenon in which the threads of the threads stick to each other (velcro effect), as if they were hook-and-loop fasteners.

The respective embodiments can be modified and embodied as follows. The mixed yarn 17 composed of a plurality of floating yarns of different tones obtained in the first embodiment may be false twisted as shown in the second embodiment.

Claims (6)

[Claims] 1. A core yarn is provided with a plurality of floating yarns, each of which is composed of primary dyed yarns colored in different colors, in a state of being randomly over-fed, and is subjected to a fiber mixing treatment by air. An air slab yarn characterized by having a slab portion and a non-slab portion which are produced by spinning and in which the color tones of respective floating yarns are randomly mixed and developed. 2. A core yarn is formed by randomly feeding a plurality of floating yarns made of different kinds of materials in a state of being over-fed and performing a fiber mixing treatment with air. An air slab yarn having a slab portion and a non-slab portion in which the properties of each floating yarn are randomly expressed. 3. A manufacturing method for manufacturing the air slab yarn according to claim 1 or 2, wherein an overfeed roller is used, the overfeed roller is randomly passed, and is overfed at random. A method for producing an air slab yarn, wherein each floating yarn is fed to a core yarn, and the core yarn and each floating yarn are mixed. 4. A manufacturing apparatus for manufacturing the air slab yarn according to claim 1 or 2, wherein the floating yarns are combined with the core yarns supplied from the core yarn supplying section, and the floating yarns are joined together. An overfeed roller for overfeeding the core yarn with a traverse mechanism for randomly feeding each float yarn to the overfeed roller; and a downstream portion of the floating yarn supply unit. And a mixed fiber mechanism that mixes the combined core yarn and each floating yarn by the disturbing action of air. 5. A woven fabric obtained by weaving using the air slab yarn according to claim 1 or 2. 6. A knitted fabric obtained by knitting using the air slab yarn according to claim 1 or 2.
