Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitted fabric having a novel design effect on the surface of the fabric, and more particularly, to a knitted fabric having a novel design effect on the surface of the fabric, and more particularly to a nep yarn having nep formed by the multifilament yarn intermittently along the longitudinal direction of the yarn. The present invention relates to a heathered knitted fabric having a surface design effect, which is formed by using, at least in part, a composite yarn obtained by doubling the present invention with other yarns.

Conventionally, nep yarn consisting of multifilament yarns has been produced by supplying wrapped yarn around the core yarn at a speed higher than that of the core yarn using a twisting machine such as a design twisting machine or an Italian twisting machine.
Nep yarn is fed intermittently to form a nep, or a rubbing body is used to create fluff on multifilament yarn.

After fuzz is generated during drawing and false twisting of the ungrinded multi-fiber yarn, it is tangled into a fluffy mass using an i-body injection device, etc.
Nep yarn tied to the neck is known. However, in all of these nep yarns, the nep simply exhibits a lumpy shape, so the fabric surface WJ#C of the aI fabric
The disadvantage is that the nap does not stand out and the surface design effect is poor.

Furthermore, the heathered knitted fabrics obtained from kudzu composite yarns by combining these NEP yarns with other yarns with different dyeability have a noticeable heather effect due to the color difference in dyeability, and the NEP effect is fully exhibited. The drawback was that it was not possible.

The present inventors first solved the shortcomings of the conventional technology of NEP yarn, and took advantage of the characteristics of NEP yarn, which is formed from only a single multifilament yarn and can be obtained in the shape of ~-de or snar μ. The purpose of the present invention is to provide a heathered knitted fabric having a novel surface design effect.

In order to achieve the above object, the present invention has the following configuration.

In other words, the present invention is a μmm fiber in which the proximal end is a nodule-shaped portion extending in the longitudinal direction of a single multi-fifty filament.
A composite yarn obtained by combining a nep yarn intermittently having at least one type of nep and snarl nep and a heterochromatic yarn having a different dyeability from the nep yarn is used at least in part. *W is a heathered knitted fabric that partially has a surface design effect characterized by a raised d# hanging surface Ifi#c nep.

Hereinafter, nine aspects of the present invention will be described in detail.

The nep yarn used in the present invention is a single multifilament yarn in which all the single yarns or a plurality of single yarn groups constituting the yarn are not cut and protrude into a loop shape in the longitudinal direction. It is a common occurrence that all the single threads or a group of single threads are not cut and the protruding threads protrude in a loop shape, and the proximal end of the protruding threads is twisted to form a snare shape. The proximal end of each nep has a knot shape formed by almost all the single threads of the threads being bundled or intertwined with each other, or a strong knot such as a knot-like twisted part. It refers to a yarn in which the yarn C is fixed at a knot-like part.

In other words, the nep yarn referred to here is not one in which the nep is entwined with the wheel in a lump and tied tightly together like in the case of conventional nep yarn, but it has a form in which the nep in the form of a nip or snarl protrudes from the surface of the yarn. It is a thread that has a new design effect that includes ruts. However, the composite yarn obtained by combining a nep yarn having the above-mentioned characteristics with a dyeable yarn having different dyeability has a different nep portion, and is not covered by the dyeable yarn. This is what stands out on the surface of the composite yarn.

The heathered knitted fabric of the present invention uses the composite yarn at least in part! ll! Before weaving 9 knits, the composite yarn and other yarns used in knitting are dyed first, or after knitting and weaving, it is piece-dyed to create a heathered fabric as shown in Figure 1. It is a heathered U41111 product with a novel surface design effect in which NEP (2) stands out on the front surface. When making ropes, when using composite yarns and other yarns together, if you use yarns of the same type as the different dyeing yarns that are combined with the nep yarn as the other yarns, the difference in the fabric will be reduced. As the proportion of dyeable threads increases, NEPs with a different tone from the dyeable threads that make up the majority of the fabric stand out from the fabric, resulting in ε! The heathered effect of the A-dyed yarn NEP yarn and the unique effect of the NEP that stands out from the fabric are even more synergistic.

9. If a yarn with a finer fineness than the NEP yarn is used as the different dyeing yarn to be combined with the NEP yarn, the proportion of the NEP yarn in the composite yarn will be smaller and the heathered effect will be reduced, but there is an objection that the NEP stands out from the fabric. Improves effectiveness.

Furthermore, if the nep yarn is covered with a different dye yarn to make a composite yarn.

The parts of the nep yarn other than the neps are covered with the discolored threads, and only the neps stand out from the discolored threads.
The unique effect of the nap that stands out from the fabric is further improved.

In the present invention, polyester A/ is used as the multifilament yarn for forming the nep yarn.

It is also possible to use thermoplastic synthetic fibers such as cotton wool, recycled fibers such as yarn and acetate, or semi-synthetic fibers, and their raw yarns.

Any type of processed yarn may be used.Furthermore, as the different dyeing thread that is to be used as a gold thread with the NEP yarn, thermoplastic synthetic fibers, synthetic fibers, semi-finished fibers, etc. Synthetic fibers, natural fibers, etc., or blended yarns.

Any blended yarn may be used, and it is possible to use not only fibers different from NEP yarn, but also fibers of the same type as NEP yarn with different dyeability through post-processing such as false twisting. ' can be done.

The present invention is based on a loop or thread in which the proximal end is a nodule-like part in the longitudinal direction of the multifilament yarn, as in the first generation.
It is a fabric that is knitted and woven using at least a part of a composite yarn obtained by combining a nep yarn having μ-shaped nep intermittently and a heterochromatic yarn with different dyeability. So.

The knitted fabric obtained by dyeing or post-dying the fabric exhibits a heathered tone due to the difference in dyeability between the nep yarn and the 7 different dyed yarns, and the knitted fabric has loops and snare ρ-shaped nep. Since it stands out on the surface of the fabric, it has a much better surface design effect than a simple block of netting.

It is possible to provide a heathered fabric having a novel surface design effect in which the heathered effect of the NEP yarn and the different dyed threads and the single color effect of the NEP that stands out from the heathered knitted fabric are mutually exhibited. It is something.

In addition, in the nep yarn of the present invention, the knot-shaped portions that fix each nep to the fiber yarn, which are formed intermittently along the longitudinal direction, have a strength that cannot be unraveled by the tension applied during processing. It is. The size of the nep can also be adjusted by changing the ratio between the supply speed to the fluid nozzle and the withdrawal speed during nep yarn production, or by using the angle between the fluid jet direction and the sloping direction of the multifilament yarn. Due to fluctuations in tension, fluid pressure, etc. during manufacturing, knots with low strength and large neps may be mixed in the nep yarn. ``However, in the present invention, the nep yarn and the different dyeing yarns having different dyeability are combined into a composite yarn by a method such as twisting, fluid entangling treatment, covering, etc.'' itself is reinforced with other yarns, and at the same time each knot-like part is also reinforced by the intertwisted and intertwined parts of other threads, and the point where the yarn Q of the composite yarn is larger than the nep yarn and the knot-like part of the nep are reinforced. The ratio of the protruding length of the nep to the yarn diameter becomes small because the nep tends to be buried in the yarn.Therefore, even if the nep yarn contains small knots and large nep, the composite yarn Because it is partially folded, the knots will not unravel due to the tension applied during processing of 9gI weaves, etc.

This prevents defects such as pulling and splashing due to the unraveling of the knots, and the protruding length of the nep protruding from the composite yarn is moderate, which not only improves unwinding properties during processing. Koto, Tsuna! The elasticity obtained by III is likely to deteriorate, and furthermore, one end of the protrusion on the surface of the fabric may be cut off, spoiling the appearance.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a partially enlarged cross-sectional view showing an example of the fabric of the present invention, in which the proximal end of the multifilament yarn (1), which is guarded by the multifilament yarn itself in the longitudinal direction, has a nodular shape. This nep yarn is woven using a composite yarn obtained by twisting and twisting different dyeing yarns (3) with different dyeability. There it is.

Loop-shaped nep (2a) and scanner μ are removed from the surface of the fabric.
A °-shaped nep (2b) is protruding.

Next is the Negya used in the present invention? The manufacturing method of the composite yarn will be explained using illustrated example 1. In Figure 2, one ma
The yarn (1) is fed into the fluid nozzle (7) via the feed loaf (&) at a feeding speed greater than the slope delivery speed by the first delivery loaf (6).

The yarn (1) introduced from the yarn inlet (8) to the fluid treatment section (9) in the fluid nozzle tv (7) is connected to the fluid treatment section (1) from the fluid introduction port (a) connected to a high pressure fluid supply source. The swirling flow of the fluid injected into the yarn (9) provides high-speed rotation with the single yarns constituting the yarn (1) being substantially converged. While the thread (1) to which torque has been applied by high-speed rotation is rotated along the swirling flow of the fluid, the air outlet 0 at the tip of the fluid processing section (9) is rotated.
Fluid nozzle A/ (7) is moved to the 1 side and pulled out with the fluid spouted from the outlet 01.
The yarn (1) pulled out is transferred to the first delivery roller (6

This nep yarn is aligned with the first delivery loaf (6) and a different dye yarn (3) separately supplied to the first delivery loaf (6). As shown in the example shown in Figure 2, if fluid entanglement treatment is used to zero-ply the main yarn and the different dyed ice strips, the manufacturing process of the nep and yarn will be improved. and the manufacturing process of the composite yarn can be made into a series of steps, and the composite yarn of the present invention can be easily obtained.

The nep yarn of the present invention can be obtained by the fluid treatment as described above, but the nep yarn and the different dye yarns are combined by the above-mentioned fluid entangling treatment, plying, covering, etc. The yarn method may be selected depending on the appearance, texture, heathered shape, etc. of the knitted fabric, and the desired application.

The present invention will be specifically explained in the following nine examples.

Example 1 A fluid nozzle (7) as shown in FIG. 3 was provided between the feed loaf 15) and the first delivery loaf (6) as shown in FIG. 2, approximately at right angles to the running direction of the multifilament yarn.

A cationic dyeable polyester yarn 75 was prepared using the same apparatus as in FIG. 2 except that the fluid entanglement treatment nozzle (6) was not installed.
D/36F' was treated under the conditions shown in Table 1 to produce a nep yarn having intermittent A/-p-like neps, snar p-like neps, and neps. Next, the above-obtained nep yarn and ordinary polyester false twisted yarn 150D/48r were twisted at 8 twists at 800 T/M to form a composite yarn.

- It was woven in a plain weave structure using 4 of the composite yarns and 9 ordinary polyester false twisted yarns of 150D/48F as warp yarns. After weaving, the woven fabric is dyed with cationic dyes and disperse dyes,
A heathered fabric was obtained. The resulting fabric has cationically dyeable polyester parts interspersed with normal polyester parts that occupy most of the surface of the fabric, resulting in a one-color difference between the two.

9. It has a heathered appearance, and NEP, which has a different color tone from the polyester portion that makes up most of the fabric, stands out from the fabric.9. It had a new collective design that combined the heathered effect and the monochromatic effect of the Kyotsude that stood out from the fabric. Furthermore, the St polymer yarn had good unwinding properties and could be unwound smoothly during fiber production.

Example 2 /48F was treated under the conditions shown in Table 1, and both steps of producing a nep yarn and producing a polymerized yarn were carried out in series. A knitted fabric with Motsukumi Funoripu structure was knitted using the composite yarn obtained above and polyester false twisted yarn 150D/48F''.Knitting,
A Shida knitted fabric was dyed with a disperse dye and a direct dye to obtain a heathered 1141 piece. The resulting rumble has a heathered appearance due to the color difference between the polyester part that occupies most of the surface of the fabric and the scattered rayon parts, and has a novel design effect in which the neps stand out from the heathered knitted fabric. Furthermore, the knitted fabric had good anti-snagging properties, and the 9-meter nap on the ground surface was difficult to break. In addition, the unwinding property of (1) yarn was also smooth during knitting in good heat, and there were no single points that appeared to be due to unraveling of the nep knots.
