Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut pile fabric having a deep color tone, a smooth surface touch, no ground cracking, an appropriate volume, and a good settling resistance, and a method for producing the same.

[0002]

2. Description of the Related Art Conventional cut pile fabrics have no means for suppressing the occurrence of crimps of latent crimped yarns at the stage of multi-filament yarns.
Dyeing (counter-dyeing) is performed after forming a cut pile fabric or a cut pile fabric in which a part of a loop pile portion is mixed (hereinafter, also referred to as a cut and loop pile fabric). FIG. 2 is a side photograph of an example of this anti-dyed cut pile fabric. The cut pile fabric obtained by this method develops latent crimps in the cut pile portion due to the heat of dyeing, the tip D of the cut pile is extremely bent, and the side face of the pile is visible, so that the cut pile fabric has a light shade. Only the surface touch was rough and hard and the quality was inferior.

In cut and loop pile fabrics,
The tip of the pile bends due to the latent crimps in the cut pile, and the sides of the pile are visible, so the difference in shade between the cut pile and the loop pile is small and the distinction between shades in both parts is unclear, resulting in poor quality. Only cut and loop pile fabrics were obtained.

On the other hand, FIG. 3 shows a side view photograph of an example of a fabric formed by dyeing (yarn dyeing) at the stage of a multi-filament yarn. This cloth has a crimp expression suppressed by the heat of yarn dyeing, and the tip D of the pile faces upward without being extremely bent. It is colored.

However, since the tip of the cut pile portion is not subjected to the rubbing action by anti-dyeing, the tip D of the pile is untwisted, and the twisted state remains as it is at the tip of the multi-filament yarn. . As a result, the surface had a strong sense of unevenness, partly appeared white, and the surface touch was rough and poor in quality.

Further, Japanese Patent Application Laid-Open No. 6-17368 discloses a cut pile tufted carpet in which the tip of the pile is made straight and straight with respect to the base fabric surface by using a heated needle, looper and knife. ing. However, this carpet had severe damage to the pile tip, did not spread, and showed a tendency to crack.

In addition, we have previously proposed Japanese Patent Application No. 4-342775.
Japanese Patent Application No. 4-342776 proposes a cut-and-loop pile fabric having a different color effect.

However, since there is no twist and there is no crimp, there is still room for improvement in terms of insufficient volume in the cut pile portion and resistance to settling.

[0009]

DISCLOSURE OF THE INVENTION The present invention solves the above problems of the prior art, has a deep color tone, smooth surface touch, no ground cracking, has a proper volume, and has good settling resistance. An object of the present invention is to provide a cut pile fabric and a method for producing the same.

[0010]

The present invention has the following constitution in order to achieve the above object.

That is, in a cut pile fabric made of twisted multi-filament crimped yarn, the shape of the fibers forming the cut pile has twist at the pile root, and the twist decreases as it goes to the pile tip. Then, the cut pile fabric is characterized by having substantially no twist and spreading radially.

Further, a multi-filament crimped yarn having a twist is wound into a wound body, the multi-filament crimped yarn is heat-set, and then used as a pile yarn, which is planted in a base cloth and at least a part thereof is set. A cut characterized by forming a cut pile fabric as a cut pile portion, and then moving the cut pile fabric so that the twist at the tip of the cut pile substantially disappears, and dyeing at a temperature lower than the heat setting temperature. It is a method for manufacturing a pile fabric.

The present invention will be described in detail below.

In the present invention, it is important to use a multi-filament yarn composed of crimped fibers in order to obtain a pile volume in a dyed cut pile fabric after the fabric is formed.

As the fiber material, synthetic fibers such as polyamide, polyester, polyacrylic, and other copolymers may be used. Among them, polyamide, polyester, or polyacrylic having excellent crimping properties may be used. Synthetic fibers are preferably used.

The single fiber fineness can be selected without any particular limitation. Generally, the range of 0.1 to 50 denier is preferable, and the range of 1 to 40 denier is more preferable.

The amount of titanium oxide contained in the monofilament is preferably 1% or less, more preferably 1% or less, based on the weight of the monofilament, from the viewpoint of obtaining an effect of increasing light absorption on the end face of the dyed cut pile. It is 0.5% or less.

Also, regarding the cross-sectional shape of the single fiber, from the viewpoint of obtaining the effect of reducing the reflection of light on the end face of the dyed cut pile, by using the irregular cross section, the gaps between the cut piles and the voids of the single fiber itself are reduced. A modified cross section is preferred as it increases and reduces light reflection. The cross-sectional shape is not particularly limited, and a flat shape, a boomerang, a triangular shape, a polygonal shape such as a square shape, and a multilobe shape such as a trilobal shape and a tetralobular shape can be selected.

Also, hollow fibers may be used. Figure 4-
FIG. 12 is a schematic diagram showing an example of the cross-sectional shape of the single fibers constituting the pile of the cut pile fabric according to the present invention. 4 is a trilobe cross section, FIG. 5 is a trilobe hollow cross section, FIG. 6 is a four lobe hollow cross section,
7 is a five-leaf hollow section, FIG. 8 is a flat hollow section, FIG. 9 is a triangular section, FIG. 10 is a triangular hollow section, FIG.
2 is a hollow hollow section.

Among these cross-sectional shapes, a polygonal shape and a multi-lobed shape are preferably used from the viewpoint of volume feeling and a different color effect, and a multi-lobed hollow cross-section is more preferably used.

In the present invention, the crimped yarn can be selected freely from latent crimped fibers such as bulked continuous fibers (BCF), composite fibers such as bimetal fibers and side-by-side fibers. However, bulked continuous fiber (BCF) or the like is preferably used.

The multi-filament yarn is composed of two or more single fibers. Specifically, spun yarn, multifilament yarn, plied yarn, color mix yarn, spun yarn, etc. are not particularly limited, but monofilament yarn or plied yarn of multifilament yarn is preferably used.

The multi-filament crimped yarn used in the present invention has a twist. The twist number may be selected according to the desired texture of the final cut pile fabric, and is not particularly limited, but is 5 to 500 T / M, preferably 10 to 400 T / M.

In the present invention, the shape of the fibers forming the cut pile has a twist at the root of the pile, and the twist becomes smaller toward the tip of the pile, and the tip of the pile has substantially no twist and is radial. It is characterized by spreading.

FIG. 1 is a side photograph showing an example of the cut pile fabric of the present invention. This will be described with reference to FIG. A is a base cloth and B is a pile. In the cut pile fabric of the present invention, the twist is gradually reduced from the pile root C to the pile tip D, and the pile tip D has substantially no twist and is spread radially. As can be seen from this figure, the pile tips D are distributed almost evenly on the surface of the fabric, and there is no cracking in the ground. On the other hand, the pile root C has twists, so it has an appropriate volume and has good settling resistance. It will be good.

On the other hand, FIG. 2 is a side photograph showing an example of a conventional cut pile cloth, and FIG. 3 is a side photograph showing another example of a conventional cut pile cloth.

As can be seen from FIG. 2, the conventional cut pile fabric, which has been subjected to anti-dyeing after forming the fabric, develops crimps due to the heat of dyeing, and the tip D of the cut pile is extremely bent and piled. Since the side of is visible, it shows a lighter shade.

Further, as can be seen from FIG. 3, the conventional cut pile fabric, which has been dyed and then formed into a fabric, does not have the tip D of the cut pile extremely bent,
Its sides are hard to see, so it shows a deep shade,
Since it was not subjected to the rubbing action due to anti-dyeing, the pile tip D was converged as it was in a twisted state, the unevenness of the surface was strong, and the surface touch was rough and poor in quality.

Further, in the cut pile fabric of the present invention, a cut pile fabric in which the cut pile portion and the loop pile portion are mixed, that is, a cut-and-loop pile fabric is provided, so that a different color effect between the cut pile portion and the loop pile portion can be obtained. Since it can be more emphasized, it is possible to obtain a cut pile fabric having a particularly excellent different color effect.

Next, a method for manufacturing the cut pile fabric of the present invention will be described.

In the present invention, it is important to make the multifilament yarn constituting the cut pile into a wound body and heat-set before dyeing.

The wound body means a state in which a thread is wound around a conical tubular tube or a perforated tube, or a straight tubular tube or a perforated tube, and the shape wound on a straight perforated tube is It is preferably used. The winding amount of the thread can be freely selected.

The winding density when the yarn is wound is 0.1 to 0.
Is preferably 5 g / cm ^3, more preferably 0.15~0.40g / cm ^3.

Here, the winding density was obtained using the following equation (I). D = W / V (I) Here, D is the winding density (g / cm ³ ), and represents the total weight W (g) of the wound yarn and the volume V (cm ³ ) of the wound yarn.

When a wound body is formed in this range and heat set, steam easily penetrates into the wound yarn, and the twisted multifilament yarn is heat set more uniformly in the length direction. preferable.

Next, in the present invention, the temperature for heat setting varies depending on the fiber material, but it is important that the temperature is higher than the dyeing temperature applied after heat setting. Further, the temperature at which latent crimps of the multi-filament yarn are developed by the heat of dyeing and the tip of the cut pile portion does not bend extremely is preferable.

The temperature at which the material is wound and heat-set varies depending on the fiber material and may be higher than the dyeing temperature suitable for the fiber material. For example, for polyamide fiber, 90 to 13
0 degreeC is preferable, More preferably, it is 100-120 degreeC. The polyester fiber preferably has a temperature of 100 to 150 ° C, more preferably 110 to 140 ° C. The temperature of the polyacrylic fiber is preferably 90 to 130 ° C, more preferably 100 to 120 ° C. A high-pressure heat setting pot is used for heat setting. The heat medium can be freely used such as hot air, steam, saturated steam, and heated steam, but saturated steam is preferably used.

Further, from the viewpoint of preventing the latent crimps from developing and preventing the tip of the pile from being extremely bent, the shrinkage rate of boiling water before and after dyeing is 1% or less, and the stretching elongation rate after boiling water treatment is 10% or less. It is preferable to select the set conditions as described above.

The boiling water shrinkage ratio and the expansion and contraction elongation ratio after the boiling water treatment are the values obtained by the following equations (II) and (III). That is, Sb = 100 * (ab) / a (II) Here, Sb shows a boiling water shrinkage rate (%). a is a polyfilament yarn of a certain length, left for 24 hours in a standard state of air in an unloaded state, with a weight of 0.1 g / denier applied to the lower end, and after 30 seconds The yarn fiber length (mm) is shown. b
Is a single filament yarn of a certain length left in standard atmosphere for 24 hours under no load, then immersed in boiling water at 98 ° C for 20 minutes under no load, and then taken out. Leave in the air for 24 hours with no load, then apply a load of 0.1 g / denier to the lower end, and after 30 seconds, the multifilament yarn fiber length (m
m) is shown. Moreover, Es = 100 * (cd) / c (III) Here, Es shows expansion-contraction expansion rate (%). c is a single multi-filament yarn of a fixed length and 2
After leaving it for 4 hours, soak it in boiling water at 98 ° C for 20 minutes without load, take it out, leave it in the standard atmosphere for 24 hours without load, and then apply a load of 0.1 g / denier to the lower end. Shows the fiber length (mm) of the multi-filament yarn after 30 seconds. d is one standard multi-filament yarn left in standard atmosphere for 24 hours under no load, then immersed in boiling water at 98 ° C for 20 minutes under no load, and then taken out in standard state After leaving it in the atmosphere for 24 hours with no load, a load of 2 mg / denier is applied to the lower end, and the multi-filament yarn fiber length (mm) after 30 seconds is shown.

The base fabric is not particularly limited, and knits, woven fabrics, and non-woven fabrics made of synthetic fibers such as polypropylene, polyester, polyamide, polyacrylonitrile, natural fibers and semi-synthetic fibers can be freely used.
A polypropylene woven fabric is preferably used.

The method of implanting the twisted multi-filament yarn in the base fabric is not particularly limited and can be freely used such as pile weaving and pile knitting tufting, but tufting is preferably used.

In the present invention, since the cut pile cloth is formed and then the anti-dyeing is performed, the cut pile portion is kneaded. It is important to prevent the rubbing action from being sufficiently transmitted to the root, so that the twist remains at the root of the pile, and a strong rubbing action is applied as it goes to the tip to untwist it, and almost no twist at the tip. .

The untwisted state of the untwisted monofilament preferably has a kneading action so that it gradually spreads radially from the untwisting start point toward the tip. By obtaining such a state, it is possible to eliminate a feeling of unevenness on the surface, obtain a smooth surface touch, have no cracks in the ground, have good settling resistance, and obtain an appropriate volume.

As the dyeing method, the Wins method or the jet dyeing method, in which the cloth is kneaded in a dye bath, is preferably used.

The dyeing temperature is lower than the heat setting temperature. At a temperature higher than the heat setting temperature or at the same temperature, latent heat crimping of the multi-filament yarn occurs due to the heat of dyeing, the pile tip is extremely bent and the side of the pile can be seen, so only a light color tone can be obtained. There's a problem.

According to the method of the present invention, when a cut pile fabric is formed, the tip of the pile is likely to appear on the surface and the side surface of the cut pile is difficult to see, and therefore, an excellent color-different effect can be obtained.

When a cut-and-loop pile cloth partially having a loop pile portion is formed by using, for example, a level cut and loop tufting machine (manufactured by Nakagawa Seisakusho Co., Ltd.), the cut pile portion and the loop pile portion are formed. Since the different color effect with the part can be further emphasized, a particularly excellent different color effect is achieved.

In the present invention, the mixture of the cut pile portion and the loop pile portion means that the cut pile portion and the loop pile portion independently form a surface on the fabric surface.

In the cut-and-loop pile fabric in which the cut pile portion and the loop pile portion are mixed, the loop pile portion is located at any position in the cut pile portion, or the cut pile portion is placed at any position in the loop pile portion. They can be distributed in shape and size, and the total ratio of the area of the cut pile portion and the total area of the loop pile portion can be freely selected. The size of the cut pile surface or the loop pile surface is, for example, 3 m in width and length.
About m, either the width or the length can be about 3 mm.

Further, in the present invention, since the fabric is formed by using the multi-filament yarn composed of the crimped single fibers, the volume is excellent and the multi-filament yarn is twisted. It is possible to obtain a material having excellent set resistance.

Further, since it is possible to manufacture an excellent cut pile fabric by anti-dyeing, there is also an advantage that it can immediately meet the consumer's color preference needs.
