Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to tufted carpets.

[Conventional technology]

Fabrics made of flat cross-section tape yarns made of polyolefin resin are commonly used as the primary base fabric of tufted carpets, and are untwisted fabrics made by wrapping spun slivers of fine fibers of 50 deniers or less with spun yarn of 50 deniers or less and binding them. It is also known to tuft a bound spun yarn into a pile yarn.

Pile yarns are usually composed of fine fibers of 50 denier or less, and tape yarns are not used for pile yarns except for tufted artificial grass.

[Problem to be solved by the invention]

Tufting is carried out by poking a needle through which the pile yarn is passed through the primary base fabric. At this time, the tape yarn of the primary base fabric is damaged by the needle, but the drawn polyolefin tape yarn is It is easy to spread the tape yarn finely in the length direction, and the tip of the spread tape yarn may be pushed out onto the pile surface.

In addition, for tufted carpets with a pile weight of less than 500 g/ ^m2 that are folded and packaged as simple rugs, and for tufted carpets that are folded and installed along stairs, the bending In some places, the primary base fabric may be exposed on the pile surface.

However, the appearance of tape yarn is too different from that of pile yarn, which is made up of ordinary fine denier fibers.
Since it has a strong surface gloss, the primary base fabric appearing on the pile surface gives a sense of discomfort and gives the appearance of a defective product.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a tufted carpet that does not give the bad impression of a defective product even if a portion of the primary base fabric appears on the pile surface.

[Structure of the invention]

The tufted carpet 16 according to the present invention was created from this viewpoint, and is made of a non-twisted bundled spun yarn 13 which is made by wrapping a spun sliver 11 of fine fibers of 50 deniers or less with a spun yarn 12 of 50 deniers or less and binding them. It is made by tufting a primary base fabric 15 woven with a flat cross-section tape yarn 14 made of polyolefin resin as a pile yarn, and a sliver 11 of the non-twisted bound spun yarn.
The tape yarn 1 is made of polyolefin resin and has the same apparent thickness as the tape yarn 14 of the primary base fabric.
It is characterized by 7 being aligned.

In this case, the pile 18 may be a cut pile or a loop pile, and the tape yarn 17 may be slit.

〔Effect of the invention〕

According to the present invention, the tape yarns 17 included in the pile yarns 13 are not twisted and continue straight and flat like the tape yarns 14 of the primary base fabric 15, and have the same gloss as the tape yarns 14 of the primary base fabric. However, since it appears uniformly on the entire pile surface that is directly visible, the primary base fabric 15
Even if the tape yarn 14, which is a part of the pile surface, appears on a part of the pile surface, it is not noticeable and does not give any sense of discomfort.

Since the tape yarn 17 included in the pile yarn 13 has a stronger luster than the spun sliver 11 made of fine denier fiber, even if the fibers of the spun sliver 11 are dull or matte, the pile yarn 17 is The entire surface has a brighter shine than would be achieved using a high-quality bright or glossy fiber spun slider, and the pile surface has a fresh appearance.

In addition, since the tape yarn 17 is significantly more rigid than the spun sliver 11, the pile 18 has a waist and is less likely to collapse, resulting in a tufted carpet with a crisp feel due to the difference in texture from the soft spun sliver 11. 16 is obtained.

As described above, according to the present invention, a novel tufted carpet can be obtained, and is particularly suitable for simple rugs that are folded and packed and a part of the primary base fabric is easily exposed on the pile surface.
The present invention is highly advantageous.
