Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven or knitted fabric having a cut pile, wherein the cut pile is made of a polyester multifilament yarn and used for interior materials and interiors of passenger cars. The present invention relates to a napped cloth suitable as the above. 2. Description of the Related Art A multi-filament yarn composed of fine denier filaments having a fineness of 1.5 denier or less is used as a pile yarn as a nap cloth having an upright cut pile to soften its texture. It has been known. However, in this case, the pile is easy to come off,
To prevent this, the feeling of napped hair disappears.To prevent this, multi-filament yarn consisting of filaments with large fineness and multi-filament yarn consisting of filaments with small fineness are aligned, ply-twisted, and evenly mixed without deviation. For example, a composite yarn is manufactured by using the composite yarn as a pile yarn of a woven or knitted fabric. It is also known that a multifilament yarn consisting only of filaments having a high fineness is knitted and woven using a pile yarn to form a cut pile, and the tip of the cut pile is made thinner by a chemical treatment. . Also, various methods are known in which a filament of a multifilament yarn used in a pile is formed into an irregular cross section to emphasize a soft feeling and to express an elegant luster by unique anisotropic reflection. However, the problem that the softness of the texture causes the hair to fall, and the problem of losing the softness of the texture when trying to prevent the hair from falling has not been solved. SUMMARY OF THE INVENTION [0004] The present invention is intended to prevent the hair from falling in a nappied fabric in which a cut pile is formed by polyester multifilament yarns if the texture of the cut pile is softened. This solves the previously unsolved problem of losing the softness of the texture, and by combining cut filaments with filaments of different flatness, the unique texture and gloss due to anisotropic reflection To make a wide variety of products. Another object of the present invention is to provide an effective means for eliminating the drawbacks of whitening and whitening caused by falling hair. [0005] The napped fabric of the present invention comprises:
In a napping fabric in which a cut pile is formed of polyester multifilament yarns, the polyester multifilament yarn is composed of at least two types of filaments having different filament fineness and flatness, and has a small fineness and a large flatness. comprising cutting the tip of the pile fineness of large, higher protrudes from the tip of the cut pile consisting of small aspect ratio filaments, fiber
Titanium oxide content of filament with low degree and high flatness
Oxidation of filaments with large fineness and low flatness
Filament that is larger than titanium content and has the smallest fineness
The fineness of the component is 2.0 denier or less, and the flatness is 1.3.
６6.0, and the fineness of the filament having the maximum fineness is 2.
More than 0 denier and 8.0 denier or less, the flatness is 1.0
And wherein 1.3 less der Rukoto more. That is, in the present invention, the pile yarn composed of the polyester multifilament yarn is composed of at least two types of filaments having different fineness and flatness. In this case, the flatness is set to be larger as the filament has a smaller fineness. This flatness is
It is defined by the ratio of the maximum diameter of the filament cross section to the maximum diameter in a direction perpendicular to the direction of the maximum diameter. The cross-sectional shape may be any one of a rectangle, an ellipse, an oval shape, a multi-leaf shape, a four-peak shape, and the like as long as it has a flatness described later. The fineness of the filament A having the smallest fineness is preferably 2.0 denier or less, and the fineness of the filament B having the largest fineness is preferably more than 2.0 denier and 8.0 denier or less. The fineness of the filament A having the minimum fineness is 2.
If it exceeds 0 denier, the texture becomes hard. On the other hand, when the fineness of the filament B having the maximum fineness is 2.0 denier or less, the hair is easily broken, and when it is more than 8.0 denier, the texture is too hard. The fineness difference between the filament A having the minimum fineness and the filament B having the maximum fineness is preferably 1.5 denier or more. The flatness of the filament A having the minimum fineness is preferably 1.3 or more and less than 6.0, and the flatness of the filament B having the maximum fineness is preferably 1.0 or more and less than 1.3. If the flatness of the filament A having the minimum fineness is less than 1.3, the effect of softening the texture and the visual effect due to the anisotropic reflection are both weakened, while if it exceeds 6.0, the production becomes difficult and the practical use becomes difficult. Not a target. On the other hand, if the flatness of the filament B having the maximum fineness is 1.3 or more, the hair falling phenomenon is likely to occur. The difference in flatness between the filament A having the minimum fineness and the filament B having the maximum fineness is preferably 2.0 or more. According to the present invention, the tip of the cut pile made of the filament having a small fineness and a large flatness projects higher than the tip of the cut pile made of the filament having a large fineness and a small flatness to make the pile surface uneven. Formed. The amount of the cut pile forming the convex portion is preferably 30 to 70% by weight of the entire pile, and if it is less than 30% by weight, a soft texture cannot be obtained.
If the content is more than 10% by weight, hair falling easily occurs. [0010] The length of the cut pile forming the convex portion is preferably 105 to 130% of the length of the pile forming the concave portion. If the length is less than 105%, the desired soft texture cannot be obtained. On the other hand, if it exceeds 130%, hair breakage easily occurs. The multifilament yarn to be the pile yarn of the present invention is arranged so that a filament having a small fineness is arranged concentrically around a filament having a maximum fineness and a filament having a minimum fineness is located on the outermost periphery. Is preferred. The preferred thickness of the pile yarn is 50 to 300 denier, and when it is less than 50 denier, the pile is easily debris. When it is 300 denier, a low gauge knitting machine is used when a warp knitting machine such as Russell is used. , The spacing between the piles is increased, the ground yarn is exposed, and the appearance is poor. In the above-mentioned pile yarn, a discharge hole having a large diameter is disposed at the center of a spinning nozzle of a polyester multifilament yarn, and a discharge hole having a small diameter and a modified cross section is disposed outside the nozzle. , A low-shrinkage polyester filament is spun from a discharge hole having a narrow, irregular cross-section on the outer periphery, and the high-shrinkage polyester filament can be produced by drawing. Then, the obtained yarn is used as a pile yarn to knit a pile fabric or a pile knitted fabric to form a cut pile, and the heat-treated heat-shrinkable polyester filament at the center is more than the heat-shrinkable polyester filament at the outer periphery. The nap fabric of the present invention can be obtained by contracting a lot. Further, a filament having a small fineness and a large flatness is spun with a polymer having a small heat shrinkage, for example, polyethylene terephthalate, and a filament having a large fineness and a small flatness is spun with a polymer having a large heat shrinkage, such as a copolymerized polyester. Spun in the form of a ribbon while running the latter multifilament yarn, and the former multifilament yarn is layered on top of it and twisted to form a composite.The resulting composite yarn is used as a pile yarn. After knitting and forming a cut pile in the same manner as described above, heat treatment may be performed. In addition, we use a double Russell machine for weaving,
The two fabrics are knitted while being joined together with the pile yarn, and the pile yarn is cut in the middle of the two fabrics.
A piece of cloth may be cut off to form a napped cloth. When the polyester filaments having high shrinkage and low shrinkage are used, the difference in boiling water shrinkage ratio between the high shrinkage polyester filament and the low shrinkage polyester filament is preferably 5 to 40%. If the difference in shrinkage ratio is less than 5%, the length of the cut pile forming the convex portion is insufficient, so that a desired soft texture cannot be obtained. Conversely, if the difference exceeds 40%, the hair tends to fall. When the polyester multifilament yarn is melt-spun, titanium oxide is generally added to the polymer in an amount of 2.0% by weight or less. In the polymer, the blending amount of titanium oxide is relatively large compared to the polymer for filaments with a large fineness that constitutes the central part,
The content is preferably 0.5 to 2.5% by weight, which makes it possible to make the whitening and whitening at the time of hair fall less noticeable as described later. However, if the amount is less than 0.5% by weight, the effect is not sufficient, and if it exceeds 2.5% by weight, troubles occur in the spinning / drawing process. According to the napped fabric of the present invention, the tip of a cut pile made of a filament having a small fineness and a large flattening ratio projects above the tip of a cut pile made of a filament having a large fineness and a small flattening ratio. Because the texture is soft, the flatness is large, and the tip of the cut pile, which has a large anisotropic reflection, protrudes from the pile surface, so that a wide variety of gloss can be obtained due to differences in fineness, flatness, protrusion height, etc. Can be expressed. Since the base of the cut pile made of a soft filament having a small fineness and a large flatness is surrounded by a high-rigidity cut pile made of a filament having a large fineness and a small flattening, hand fall hardly occurs. When the titanium oxide content of the filament constituting the cut pile is small, the end face of the cut pile looks dark, and the side face has a high reflectance, so that it looks shiny and bright, and the difference is the cause of white blur and whitening. However, in the napped fabric of the present invention, when the titanium oxide content of the filament having a small fineness and a large flatness is larger than that of the filament having a large fineness and a small flatness, the end face and the side face of the cut pile are reduced. The difference in the reflectance of light is small, white blur and whitening are less noticeable, and the filament having a large fineness and a small flatness has a low titanium oxide content, and the darkness of the end face of the cut pile composed of the filament is reduced. Absorbs reflected light due to hair fall and produces a synergistic effect in combination with the fact that the cut pile with small fineness is flat and has anisotropic reflectivity. , White blur-whitening phenomenon is improved. The fineness of the filament having the minimum fineness is set to 2.0 denier or less, the flatness thereof is set to 1.3 to 6.0, and the fineness of the filament having the maximum fineness is set to more than 2.0 denier and 8.0 denier or less. , Its flattening rate is 1.0 or more and 1.3.
When it is limited to less than 3, the texture becomes more flexible, and hair fall becomes more difficult to occur. EXAMPLE A spinning nozzle having 18 large fineness discharge holes at its center and 32 small fineness discharge holes arranged around its periphery was used. From the fineness discharge hole, copolymerized polyester (copolymerized component: isophthalic acid, isophthalic acid content: 10 mol%, titanium oxide content:
0.03% by weight) and polyethylene terephthalate (titanium oxide content: 0.6
% By weight) and stretched to give a 3.7 denier large fineness filament (flatness:
1.0%, hot water shrinkage: 15%), 18 filaments around which 1 denier small fineness filament (flatness: 4.0)
%, Hot-water shrinkage: 5%) to produce a multifilament yarn (total fineness: 100 denier, total number of filaments: 50) having 32 filaments. The above multifilament yarn (100 denier / 50 filament) was used as the pile yarn, and the polyester multifilament yarn (100 denier / 50 filament) was used as the ground yarn. Knit a heavy knitted fabric (density: 44 courses x 22 wales)
The pile yarn was cut in the middle of the knitted fabric to separate the two knitted fabrics, and the obtained two greige machines were brushed and preset. Next, the greige fabric was subjected to high-temperature dyeing (130 ° C. × 60 minutes) according to a conventional method, dried, and then subjected to a finishing set and a brushing treatment to obtain a napped fabric of Examples shown in the following table. Table Example Comparative example Small fineness filament in the periphery Fineness (denier) 1.0 1.0 Flatness (%) 4.0 1.0 Number of filaments (number) 32 32 Composition ratio (%) 32 32 Titanium oxide content (%) 0.03 0.6 Pile height (mm) 2.5 2.5 Large fineness filament in the center Fineness (denier) 3.7 3.7 Flatness (%) 1.0 1.0 Number of filaments (pieces) 18 18 Composition ratio (%) 68 68 Titanium oxide content (%) 0.6 0.6 Pile height (mm) 2.1 2.1 The obtained napping fabric of the embodiment has an extremely soft feel, has no pile set-off, and is not whitened or whitened even when the pile is strongly pressed with a finger. Few were recognized. Comparative Example A spinning nozzle having 18 large fineness discharge holes at its center and 32 small fineness discharge holes arranged around its periphery was used. A copolyester (copolymer component: isophthalic acid, isophthalic acid content: 10 mol%, titanium oxide content: 0.03% by weight) is discharged from the discharge hole, and polyethylene terephthalate (titanium oxide) is discharged from the discharge hole for small fineness around. (The content: 0.03% by weight) was spun and stretched to obtain 3.7 at the center.
It has 18 denier large fineness filaments (flatness: 1.0%, hot water shrinkage: 15%), and 1 denier small fineness filaments (flatness: 1.0%, hot water shrinkage) around it. : 5%) 32 multifilament yarns (total fineness: 100 denier, total number of filaments: 50)
Was manufactured in the same manner as in the above example, except that this multifilament yarn was used as a pile yarn, to obtain a napped fabric of a comparative example shown in the above table. The obtained raised fabric had a soft feeling and no pile set, but the flatness of the surrounding small fineness filament was 1.0 and it was not flat, so the texture was poor in softness and the gloss was equal. Since the pile was anisotropic, had little change, and contained a small amount of titanium oxide, when the pile was strongly pressed with a finger, white blur and whitening were conspicuous. According to the present invention, there is provided a napped fabric having a cut pile formed of polyester multifilament yarn,
The above-mentioned polyester multifilament yarn is composed of at least two kinds of filaments having different fineness and flatness of the filament, and the tip of the cut pile composed of the filament having small fineness and high flatness has high fineness and low flatness. high protruding though Luca et than the tip of the cut pile consisting of filaments, the texture is a soft, hair fall is not generated, yet exhibit unique texture by mixing the cut pile consisting of aspect ratio different filaments, and Anisotropic reflection occurs, causing the gloss to vary widely. In addition, since the titanium oxide content of the filament having a small fineness and a large flattening ratio is made larger than the titanium oxide content of the filament having a large fineness and a small flattening ratio, the hair may fall down. Even when whitening occurs, whitening and whitening are not noticeable. Furthermore, the fineness of the filament having the minimum fineness is not more than 2.0 denier, and the flatness thereof is 1.3 to 6.0.
7. The fineness of the filament with the maximum fineness is more than 2.0 denier.
Since the denier is limited to not more than 0 denier and not more than 1.0 and less than 1.3, the texture becomes softer and the hand fall hardly occurs.
