Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile cloth suitable for use in vehicle interiors, home interiors, office interiors, exhibition hall interiors, clothing, etc.

[0002]

2. Description of the Related Art Conventionally, fabrics for vehicle interiors are woven fabrics,
Various fabrics such as knits, pile woven and knitted fabrics, leather, and leather-like fabrics are used. Among these, the cloths that are particularly often used are pile woven fabrics called moquette, tricot raised cloths, and double Russell knitted fabrics.

As a means for improving these fabrics, Japanese Unexamined Patent Publication No.
As seen in Japanese Patent No. 321060, a method of mixing fibers having different contraction rates so as not to fall over when used is proposed.

Further, in order to improve the white blurring phenomenon peculiar to pile fabrics, for example, JP-A-62-268855,
In Japanese Patent Laid-Open No. 63-105143, the polyester fiber used as the pile yarn has a core-sheath structure, and the sheath component uses a component that is deeper and more easily dyed than the core component.

Further, in order to obtain a silk-like pile cloth,
For example, Japanese Patent Publication No. 6-21398 proposes to use a fineness mixed fiber having a modified cross or T-shaped cross-section. JP-A-62-21842,
Japanese Patent Application Laid-Open No. 63-59454 also proposes a flat yarn which has a soft texture and improves the feeling of nap and the feeling of see-through.

Further, as a method for obtaining a napped pile fabric which does not fall over with a soft texture in Japanese Patent Laid-Open No. 63-126941, at least two types of filaments are used, and a filament having a small fineness is mainly a filament having a large fineness. There is proposed a napped fabric in which the tips of filaments having a small fineness are arranged so as to surround the periphery thereof and project higher than the tips of filaments having a large fineness to form irregularities on the tip surface of the cut pile.

However, in any of the above-mentioned prior arts, while having a soft texture, the hair has a good resistance to hair collapse, and the covering property of the pile surface is high, and further, the pile surface has a three-dimensional feeling of lightness difference or hue difference. It has not been possible to obtain a heathered pile fabric having the characteristics of having excellent print coloring properties.

[0008]

DISCLOSURE OF THE INVENTION The present invention has a soft texture, a good hair collapse resistance, a high covering property on the pile surface, and a three-dimensional feeling of lightness difference or hue difference on the pile surface. And to provide a heat-tone pile cloth having good print color development.

[0009]

The present invention has the following constitution in order to solve the above problems.

That is, 20 to 100% by weight of the fibers constituting the pile portion of the pile fabric has a wall thickness of 1.5 to 6.5 μm.
Which is a modified I-shaped cross-section polyester fiber, and 1.5% by weight of a matting agent is used as the fiber constituting the pile portion.
At least three types of polyester fibers A substantially not dyed with a cationic dye, polyester fibers B substantially 0.7% by weight or less containing a matting agent and not dyed with a cationic dye, and polyester fibers C dyeable with a cationic dye. All of the polyester fibers of No. 2) account for 20% by weight or more of the fibers constituting the entire pile portion and are used in combination without exceeding 60% by weight.

[0011]

Pile fabric of the embodiment of the present invention is varying in thickness 1.5~6.5μm described later in fibers constituting the pile portion
Shape I Shape Cross section 20 to 100% by weight of polyester fiber
It includes.

FIG. 1 is a schematic diagram showing an example of a modified I-shaped cross-section polyester fiber having a wall thickness of 1.5 to 6.5 μm which constitutes the pile fabric of the present invention .

[0013] The wall thickness of the fiber in the present invention means the pile yarn
1000 times electron microscope for a cross section perpendicular to the fiber axis
Take a microscopic picture, figure1AsFineInscribed in cross section
The center of the largest inscribed circle when drawing a circle
The fiber surface closest to the fiber surface as the center of the cross section
At a distance of tμmI measured about 20 pile fibers
It means the average value of the time.

In the present invention, the deformation that constitutes the pile portion
The thickness of the I-shaped cross section polyester fiber is
It is an important factor that contributes to the covering property of the pile surface and the print coloring property.
It is necessary that the weight% or more has a wall thickness in the range of 1.5 to 6.5 μm. The wall thickness is preferably 1.5 to 6 μm, and more preferably 1.5 to 5 μm. By having a cross-sectional shape with a wall thickness in this range, it is excellent in hair fall resistance and covering property of the pile surface, and the pile is well dispersed and napped without worming, so that print paste and dye are applied to the pile surface. Since it is easy to adhere evenly, the coloring and pattern after print dyeing are drawn sharply.

Further, in the printing, compared to the submerged dyeing, only the fiber surface is dyed, which is a so-called ring dyeing state, but the modified I-shaped cross section having a thickness of 1.5 to 6.5 μm of the present invention. Pile cloth using polyester fiber has less dyed area inside the fiber even if it is ring dyed, and the undyed area is reduced. This has the effect of reducing the discharged area.

However, if the wall thickness is less than 1.5 μm,
This is desirable from the viewpoint of more excellent print coloring, but the modified I-shaped cross-section yarn inevitably becomes longer in the longitudinal direction of the fiber cross section. That is, since the flattening progresses too much, the hair collapse resistance, which is a required characteristic of a pile fabric, decreases (the pile easily falls), and the problem of fibrillation occurs .

On the other hand, when the wall thickness exceeds 6.5 μm, the ring dyeing condition becomes tight, the unexposed area increases, and the covering property of the pile surface is affected, resulting in poor print coloring. In addition, increasing the wall thickness leads to the direction of reverse flattening (that is, spherical tendency) and improves hair drop resistance and white blur resistance, but it becomes slightly stiff in terms of texture, Problem arises.

Further, fibers having a particular thickness constituting the pile portion may be in the form Shiki modification I-shaped cross section of the dogbone as shown in FIG. 1, to improve the耐毛collapse of it can.

Further, in the present invention, the fibers constituting the pile portion are polyester fibers A containing 1.5% by weight or more of a matting agent and substantially not dyed with a cationic dye (hereinafter abbreviated as "fiber A"). ), 0.7% by weight of matting agent
It comprises at least polyester fibers B (hereinafter abbreviated as "fiber B") which are substantially not dyed with a cationic dye and cationic dye-dyeable polyester fibers C (hereinafter abbreviated as "fiber C") contained therein. It is a thing.
The proportion of fiber A, fiber B and fiber C is at least 20
It is necessary to set the content to be not less than 60% by weight because of the relationship with other components.

The amount of the matting agent contained in the fiber A was 1.
It may be 5% by weight or more, but considering the process stability in the spinning process and the fiber manufacturing cost, the effect of the present invention can be achieved with a content of at most 7% by weight. Further, the fiber B also includes fibers containing no matting agent. The matting agent is not particularly limited, but titanium oxide is a typical example, and inorganic particles such as silicon oxide and aluminum oxide are also included, but organic particles may also be used.

When the pile A is dyed, the fiber A containing a large amount of the matting agent has the effect of increasing the lightness due to the diffuse reflection effect of the matting agent. On the other hand, the lightness of the fiber B having a small amount of the matting agent due to the diffuse reflection effect of the matting agent becomes low. And fiber A
Since the composition of polyester is different from that of the fiber C and the fiber B has a smaller amount of dye adsorbed and higher brightness, three types of feeling of feeling, that is, three feelings of heat due to the difference in brightness can be expressed.

In order to effectively express the feeling of looseness, it is preferable that the difference in the content of the matting agent contained in the fibers A and B is large, and specifically, it is preferably 1% by weight or more. .

Further, when fibers A, B and C are dyed in the same bath with a combination of a cationic dye and a disperse dye, fiber A
Since the fiber C is dyed only with the disperse dye, and the fiber C is dyed with both the cationic dye and the disperse dye, the fibers A and B and the fiber C can be dyed in different hues. In addition, there is an effect that it is possible to easily obtain a three-dimensional feeling with a hue difference. Examples of the polyester fiber dyeable with a cationic dye include, for example, Japanese Patent Publication No. 34-10497.
As can be seen in Japanese Examined Patent Publication No. 1-20248, copolymerization of an isophthalic acid component containing a metal sulfonate group,
Alternatively, a fiber can be formed by using a modified polyester obtained by copolymerizing an isophthalic acid component containing a metal sulfonate group and a glycol component having a molecular weight of 400 to 6000.

If any of the proportions of the fiber A, the fiber B and the fiber C is less than 20% by weight, the proportions of the pile constituent fibers of the lightness difference and the hue difference obtained by the respective fibers will be low and the balance will be unsatisfactory. I can't get a feeling.

Fiber A, fiber B or fiber C is
The modified I-shaped cross-section polyester fiber in the wall thickness range of the present invention may be used alone, or may be a mixture of other cross-section fibers such as a round cross-section fiber, a trilobal cross-section fiber, and a flat cross-section fiber. . In particular, taking the case of combining modified I-shaped cross-section fibers and round-shaped cross-section fibers as an example, modified I-shaped cross-section fibers are usually polyester fiber A containing a large amount of matting agent and fiber B containing less matting agent. It is preferable that the round cross-section fiber is made of a cationic dye-dyeable polyester fiber C and has a small amount of matting agent, because the effect of the combination is more clear, and the hair drop resistance and fibril resistance can be improved.

In general, the term "heather feeling" refers to a pile having a high lightness and a pile having a low lightness, or a pile having a hue difference and a saturation difference, which are present as a group and have a granular shape. For the feeling of heat, pile with high brightness,
Pile with medium lightness and pile with low lightness or piles with different hues are present as a group with each other, and in addition to those exhibiting graininess, piles having these lightness difference and hue difference exist in a dispersed state, so-called marbling It also includes things.

In the pile fabric of the present invention, the fiber A, the fiber B and the fiber C of the fibers constituting the pile portion have a single fiber fineness, a resistance to hair collapse, and a splintering phenomenon of the fiber, so as to prevent so-called fibrillation, from 1 denier It is preferably 6 denier or less from the viewpoint of obtaining a soft texture and preventing ring dyeing.

When the heathered pile fabric is used for vehicles, the texture and the hair-fall resistance are important required properties of the pile. Generally, the pile side surface of the fibers that make up the pile portion is likely to appear on the surface, so when light hits the pile surface, it tends to be specularly reflected, and the specularly reflected light, that is, white light tends to be high depending on the viewing direction, a phenomenon called white blur Is likely to occur. From the viewpoint of preventing such white blurring, it is preferable in the present invention that the fibers B and C constituting the pile portion contain 0.01% by weight or more of a matting agent such as titanium oxide.

The fibers forming the pile portion of the pile fabric are
A small amount of natural fibers such as wool, cotton and silk, and synthetic fibers such as polyamide and polyacrylic may be contained, but especially for vehicles where light resistance is required, 100% by weight polyester is preferable. .

The heathered pile fabric of the present invention has a soft texture even in plain dyeing or printing, has a good resistance to hair collapse, has a high covering property on the pile surface, and has a lightness difference on the pile surface. Also, it has the effect of having a feeling of three shades of hue difference. Above all, it is more effective if the fibers A, B and C that make up the pile portion are dyed with cotton, thread, or dyed in a cloth liquid, and printed by discharge printing, or by color printing after discharge printing or print containing discharge agent. Target.
These print pile fabrics have the above-mentioned soft texture, good hair collapse resistance, high covering property on the pile surface, and the effect that the pile surface has a feeling of lightness difference and hue difference and excellent printing. Exhibits color development.

The pile yarns of the heathered pile fabric may be in the form of spun yarn, filament yarn form, air-processed yarn such as Taslan or filament-processed yarn form such as temporary twist, and further, those spun yarn and filament yarn. Of composite yarn and mixed weave
A mixed form such as a mixed knitting may be used. Further, the pile fabric structure is not particularly limited, and may be in the form of a knitted fabric such as a moquette such as a pile fabric, tricot, and double russell.
