DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the pile yarn of the present invention
It has a twist structure composed of at least four fibers in which at least two bulky multifilament yarns of thermoplastic synthetic fiber and at least two monofilament yarns of thermoplastic synthetic fiber are twisted.

By using a pile yarn having a twist structure composed of at least four yarns, the bulkiness and elasticity of the bulky multifilament yarn are improved.
The rigidity and resilience of the monofilament yarn are integrated with each other, and a pile yarn is obtained in which the characteristics of both yarns are combined. Of course, the bulky multi-filament thermoplastic synthetic fiber yarn and the thermoplastic synthetic fiber monofilament yarn constituting the pile yarn may be four or more yarns, for example, six or eight yarns. Can be selected as appropriate.

Further, the pile yarn of the present invention has a twist structure of a ply-twist, a middle-twist, and a ply-twist, and by having the same twist structure, the bunching property of the bulky multifilament yarn and the monofilament yarn is improved. , Dust removal when matted,
This leads to improvements in dust catching properties, elasticity, and the like, as well as improvements in pile yarn durability and surface quality.

In the pile yarn of the present invention, it is preferable that the twist direction of the primary twist of each yarn constituting the pile yarn is the same. By setting the twist direction of the lower twist in the same direction as described above, the form of the pile yarn becomes uniform, which leads to improvement in dust removal performance, appearance, quality of the mat, and the like.
On the other hand, when the twist direction of the lower twist is different, the form of the pile yarn becomes uneven due to the different torque direction of each constituent yarn, and the dust removal performance of the mat, appearance, quality degradation, and even those with different twist directions are simultaneously Since the production is performed, the setting of the processing conditions, the product classification, and the like become complicated, which leads to a decrease in productivity, which is not preferable. It is important to appropriately select whether the twisting direction of the primary twist is the same direction or a different direction in terms of balancing the twisting torque depending on the type of yarn.

In the pile yarn of the present invention, it is more preferable that the number of ply twists of the constituent yarns is the same from the viewpoint of productivity.
The application of a direct cable-type twisting machine or the like which can simultaneously apply the lower twist and the upper twist can be exemplified. On the other hand, when the material and thickness (denier) of each of the constituent yarns are different, the torque of each of the constituent yarns is different if the number of ply twists is the same. The number of ply twists of each component yarn should be set in consideration of the balance between the process passability, pile form, mat quality, number of medium twists and number of twists, as this may lead to non-uniform shape and lower mat quality. Is essential. In this case, it does not matter if any of the constituent yarns does not have a priming.

In general, the number of lower twists and the number of upper twists are 100 to 4
00 times / m, the number of twists is preferably 200 to 800 times / m,
More preferably, the number of lower twists and the number of upper twists are 150 to 300.
Times / m, the number of twists is 300 to 600 times / m.

The bulky multifilament yarn and monofilament yarn of the thermoplastic synthetic fiber used for the pile yarn of the present invention are at least one selected from polyamide fibers, polyester fibers, polypropylene fibers and acrylic fibers. In particular, as the bulky multifilament yarn, a continuous bulky multifilament yarn generally used for rugs, carpets, mats and the like is preferable.

Further, these fibers used in the present invention are:
When they have different colors or different dyeing properties from each other, it is possible to express multicolor heather, and it is possible to give a sense of quality and add value.
Further, these bulky multifilament yarns and monofilament yarns may be original fibers, or these fibers may contain the same type or different types of fibers. And the like, and by these, it is possible to provide a pile yarn with further improved new features, for example, a multicolor effect, an antistatic effect, a convergence property and the like.

The two bulky multifilament yarns and the monofilament yarns used in the present invention have a difference in denier, difference in cross-sectional shape, difference in shrinkage, difference in elongation between the two yarns.
Even if it has a difference in gloss, a difference in crimp, etc., it does not matter at all, and it can be used in an appropriate combination according to the intended use of the pile yarn.

The bulky multifilament yarn used in the present invention preferably has a single yarn denier of 5 to 300 denier, more preferably 10 to 200 denier, more preferably about 10 to 100 denier, and a total denier of 300 to 100 denier. 3000 denier is preferable, 500 to 2500 denier is more preferable, and 8 is more preferable.
It is 00 to 2000 denier. If the single yarn and total denier are thin, the pile will not be waisted and the stepping feeling will be poor,
Further, durability is undesirably reduced. Also, when the denier of single yarn becomes thicker, the coarseness of the pile increases,
The shape retention of a pile having a total denier exceeding 3,000 deniers is undesirably reduced.

The monofilament yarn used in the present invention preferably has a denier of 100 to 1500, more preferably 200 to 1000 denier. If the thickness is less than 100 denier, the rigidity is weakened and the dust removing effect is reduced. If the thickness is greater than 1500 denier, the shape retention of the pile is undesirably reduced.

When a mat is produced by tufting using the pile yarn of the present invention, the pile shape may be any of a cut pile and a loop pile, but a cut pile is preferred from the viewpoints of dust removal effect and appearance.

Further, in the pile yarn of the present invention, the respective yarns constituting the pile yarn are bundled by medium twist and ply twist,
The multifilament yarn and the monofilament yarn, which are constituent yarns, form a twisted structure with different phases and are integrated.
As described above, the multifilament yarn and the monofilament yarn form a twisted structure having different phases and are integrated, so that the monofilament yarn has a portion partially covered by the multifilament yarn, and the bunching property is further improved. It is.
