Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile cloth which is made by a tufted machine, a moquette loom, a double Raschel warp knitting machine, and is lined and used for a carpet or the like.

[0002]

2. Description of the Related Art A plied yarn is prepared by using a plied yarn in which a thick twisted yarn is entangled with a thin twisted yarn and heat-set.
1720), or a twisted yarn of two types of yarns having different crimp degrees of fibers is used as a pile yarn (Jitsuko Sho 47-2030).
No. 2), or 3 of high shrinkage yarn, medium shrinkage yarn and low shrinkage yarn
For example, by using pile yarns interlaced by interlacing various types of filaments (Japanese Patent Laid-Open No. 63-1454).
No. 57), it is known to form cut piles in which short pile fluff and long pile fluff are mixed.

According to these known techniques, one cut pile is composed of several types of pile fluff whose length is different depending on the degree of crimp of the fiber, and the short pile fluff is under the long pile fluff. , Short pile fluff appears and disappears depending on the angle and direction of the pile surface, and the iridescent effect occurs in which the pile surface changes in color with depth.

[0004]

By the way, on the pile surface of the greige machine immediately after weaving and weaving, there are irregularities due to the weaving and knife steps that occur during the weaving and weaving process, and irregularities corresponding to the thickness of the looper called J-cut. Therefore, in order to eliminate it, a shearing process is carried out in which the pile surface is cut flat.

However, in the shulling process, the pile surface may sometimes be cut more deeply than necessary, and the pile surface may have to be cut deep depending on the degree of unevenness due to knife steps or J cuts.

In such a case, the difference in the length of the pile fluff that is bent may disappear due to the difference in the crimp of the pile fiber, which makes it impossible to obtain a pile fabric whose color tone changes to iridescent.

Therefore, the object of the present invention is to provide the pile effect on the pile surface that does not disappear even when deeply mowed by shearing.

[0008]

In the pile fabric according to the present invention, a substantially non-twisted multifilament in which substantially untwisted filaments having no crimps and straight fiber axes are aligned is prepared. The yarn 11 and the multifilament yarn 11 are aligned with a substantially non-twisted spinning sliver 12 which is a short fiber having crimps having different dyeability, and the bundle filament yarn 13 is wound to form the multifilament yarn 11. The cut pile 15 is formed by using the untwisted bundle spun yarn obtained by binding the spinning sliver 12 as the pile yarn 14, and the cut pile surface 1 is formed.
The spinning sliver 12 is colored by printing a dye having no dyeing property on the multifilament yarn 6 and the printing pattern 17 by the pile fluff of the spinning sliver 12 is drawn.

Here, "substantially untwisted" means that when the multi-filament yarn or pile yarn wound around a bobbin is pulled out in the axial direction of the bobbin without rotating the bobbin, the circumference of the bobbin ( Twisting occurs once per (length), but 1 per 10 cm.
Twisting that occurs at a rate of less than or equal to the number of turns means that it is regarded as untwisted, not counted as twist.

To wind the filament yarn 13 by aligning the multi-filament yarn 11 and the spinning sliver 12 with each other, JP-A-63-42958 (Japanese Patent Publication No. 3-25541).
No.), the spinning sliver 12 pulled out from the spinning card is passed together with the multi-filament yarn 11 through the hollow shaft core of the bobbin wound with the filament yarn 13, and the bobbin is rotated together with the filament yarn 13. It can be pulled out from the hollow shaft core.

FIG. 1 illustrates a tufted carpet according to the present invention, in which pile yarn 14 is tufted onto a base fabric 19 to form cut pile 15.

The pile surface 16 is a multifilament yarn 1
1 and the pile fluff of the spinning sliver 12 and the fibers are crimped, the pile fluff of the spinning sliver 12 is slightly shorter than the pile fluff of the multi-filament yarn 11, and the tip of the pile fluff of the multi-filament yarn 11 is a frosted pattern. It sparsely sticks out on the pile surface so as to draw.

The pile surface 16 is screen-printed, and the pile fluff of the spinning sliver 12 is color-coded in a pattern. On the other hand, the pile fluff of the multi-filament yarn 11 is not colored with a printing paste and is printed as a white cloth. Pattern 17
It sparsely protrudes on the pile surface so as to cover the surface of.

EFFECTS OF THE INVENTION Depending on the presence or absence of crimp between the constituent fibers (single fiber / filament) of the multifilament yarn 11 and the constituent fibers (short fibers) of the spinning sliver 12, the pile fluff forming the cut pile 15 has long and short fluff. There is a difference,
This causes an iridescent effect on the pile surface.

At the same time, in a non-twisted multi-filament yarn 11 in which filaments having no crimps, that is, fine fiber axis cores and not crookedly bent are aligned in parallel, the side surfaces of the filaments are in close contact with each other. While its side surface has a silky luster, its cut surface appears dark due to the fine shadows formed in the gaps in the cross sections of closely aligned filaments. On the other hand, in the spinning sliver 12, which is an aggregate of short fibers crimped and finely bent, the pile fluff is loosely opened and many gaps are formed, so that silky luster is not observed on the side surface. There is no noticeable difference in appearance between the side surface and the cut surface as in the multifilament yarn 11. Therefore, the iridescent effect in the present invention is a complicated one in which the difference in gloss between the side surface of the multifilament yarn 11 and the cut surface and the difference in length of the pile fluff are mixed.

The iridescent effect in the present invention is not only due to the difference in the length of the pile fluff, but the difference in gloss between the side surface of the multifilament yarn 11 and the cut surface is the spinning sliver 1.
It is seen in detail between the pile fluffs of No.2.
Moreover, since the glittering silky luster on the side surface of the multifilament yarn 11 attracts the eyes strongly, even if the pile surface is deeply cut in the shulling process, it is not said that the bead effect is completely lost.

The pile fluff of the spinning sliver 12 thus mixed serves to enhance the silky luster of the side surfaces of the multifilament yarn 11, so to speak.

Therefore, the mixing ratio of the multi-filament yarn 11 and the spinning sliver 12 is about 2-8: 8-2.
That is, the ratio of the total denier of the multi-filament yarn 11 to the total denier of the spinning sliver 12 should be 2 to 8: 8 to 2, and preferably 50 to 50.
Further, the ratio of the denier of the monofilament of the multifilament yarn 11 to the denier of the monofilament of the spinning sliver 12 is preferably about 1 to 2 to 2-1 and substantially the same thickness.

The binding filament yarn 13 is for binding the multi-filament yarn 11 and the spinning sliver 12 until the cut pile is formed, and it is desirable that it does not appear on the pile surface. For that purpose, the total denier of the binding filament yarn 13 is not more than 1/10 of the total denier of the pile yarn 14, and
The denier of the monofilament of the multifilament yarn 11 and the denier of the monofilament of the spinning sliver 12 are preferably 10 times or less.

The conventional tufted pile fabric 18 has a pile interval of generally 5/32 inch to 1/10 inch, a pile length of generally 7 to 10 mm, and a pile density conventionally used for vehicle seat fabrics. Since the pile 15 is coarser than that of the moquette, the pile 15 tends to fall forward, backward, leftward, and rightward. However, in the present invention, the pile yarn 14 is non-twisted, and the fiber axis is straight in the pile 15 so that it is not slippery. Since the crimped multi-filament yarns 11 are mixed, the pile 15 is more likely to fall forward, backward, leftward and rightward.

Therefore, the direction in which the side of the multi-filament yarn 11 exhibiting a glittering silky luster changes randomly depending on the direction in which the pile 15 falls, and the iridescent effect on the pile surface is the silky luster that appears randomly. Since it appears dazzlingly on the printed pattern 17, the pile fabric according to the present invention exhibits a variety of aesthetic and rich aesthetics.

The dazzling action of the multifilament yarn 11 is due to the glittering silky luster of the side surface of the multifilament yarn 11 rather than the color of the multifilament yarn 11.
The multifilament yarn 11 may be an undyed white fabric, and therefore only the pile fluff of the spinning sliver 12 needs to be dyed at the time of printing.

In order to increase the gloss difference between the multifilament yarn 11 and the spinning sliver 12 and to promote the dazzling action of the multifilament yarn 11, polyester fiber having a high refractive index is used for the multifilament yarn 11 and spinning is performed. For the sliver 12, it is effective to use an acrylic fiber which has a different dyeing property and a lower refractive index.

As described above, according to the present invention, the difference in length of pile fluff due to the difference in crimping, the difference in gloss between the side surface and the cut surface of the multifilament yarn 11, and the difference in gloss between the multifilament yarn 11 and the spinning sliver 12. The pile surface 16 has a colored worm effect, and the printed pattern 17 is printed.
A new pile fabric 18 in which is visible and hidden is obtained.

Further, in the present invention, the pile yarn 14 is a non-twisted bundle spun yarn which is easy to be separated into individual fibers, and the non-crimped multi-filament yarn which is slippery and slippery is interposed therein. Therefore, the cut pile 15 easily falls in various directions, and the bead effect also changes depending on the direction in which the cut pile 15 falls, so that the pile surface has various changes.

Since this bead effect is not only due to the difference in length of pile fluff, it does not disappear during the shearing process. Therefore, according to the present invention, unevenness due to knife steps or J cuts is produced in the weaving and weaving process. It is easy to make and is convenient for cut pile fabrics that require a shirring finish.
