Description

  The present invention provides a pile of piles formed from processed yarns having different thicknesses, imparts a pattern according to the brightness of the piles having different thicknesses, and provides a design difference in tile carpet by providing a difference in pile height. By reducing the uncomfortable feeling of the pattern of the joint part that has been impossible in the past from the point of view, it is possible to perform the tile carpet flow pasting, which is difficult because the pasting is impossible, and so-called The present invention relates to a tile carpet that can remarkably improve the design properties at the time of construction of the tile carpet, such as enabling design pasting.

  Conventionally, tile carpets formed in a predetermined shape have been widely used as floor carpets for buildings and general houses. As the demand for tile carpets has increased, there has been a strong demand for improvements in design from the market. Therefore, tile carpets that have been provided with patterns by printing or by forming piles with pre-colored processed yarn, etc. Is provided. In particular, a tile carpet provided with a pattern can embody a three-dimensional design by a pile composed of processed yarns provided with two or more colors, and can express a unique texture. In addition, tile carpets that form tufts, especially with straight tufts, can embody straight lines of patterns and patterns, and the demand for these straight tuft patterns and patterns continues to increase because they combine luxury and simplicity.

  However, the tile carpets patterned with piles of two or more brightnesses and colors, especially the tile carpets formed with tufts by straight tufts, have individual tile carpets derived from the limit of accuracy when punching into tile shapes. There was a shift in the pattern / pattern. When the pattern / pattern is displaced by pouring the tile carpet, that is, when the pattern / pattern is laid in parallel to the stitch direction, the pattern / pattern displacement of the joint area of the tile carpet is noticeable at the joint area. It was inevitable that the design of the overall pattern / pattern on the construction surface was lowered when laying.

For this reason, tile carpets with tufts formed by straight tufts cannot be applied by sinking, and are limited to checkered application only. On the other hand, in order to alleviate such problems, tile carpets using a needle shift method are provided in which piles are formed not in a straight line but in a W shape, for example, and piles are provided on the entire surface.

However, in the case of a tile carpet in which a tuft is formed by the needle shift method, it has been very restricted from the viewpoint of the design of the tile carpet, such as the provision of a linear pattern with a large demand. Therefore, even if the design characteristics such as the store market are regarded as important, tile carpets cannot be washed and pasted, and only limited to checkered pasting, and the degree of freedom of design of the construction surface by the conventional tile carpet is It was extremely limited. In addition, by combining the conventional tile carpet, the degree of freedom of design imparting by so-called design pasting (hereinafter referred to as design pasting) that embodies a high design on the entire construction surface is extremely limited. Although the problem has been desired to be solved, the technology to be solved has not yet been provided.

  Therefore, the present invention solves the above-mentioned problems, and greatly reduces the incongruity of the tile carpet pattern that was conspicuous by the flow pasting, and enables the flow pasting, so that in the conventional design aspect Tile that allows various design pasting that was impossible, further improves the degree of freedom in design design of tile carpets such as design pasting, and gives designability of the entire construction surface that could not be imparted conventionally Challenge to provide carpet.

As a means for solving the above-mentioned problems, the present invention provides a tile carpet in which a pile is formed on a base fabric as described in claim 1 and a backing layer made of a thermoplastic resin is formed on the base fabric. A pile of piles formed from 1000 to 1500 dtex processed yarn 1 on the cloth and a processed yarn 2 of 2000 to 3000 dtex having a pile height 1.0 to 3.0 mm higher than the pile height formed from the processed yarn 1 The lightness of a part or the whole of the pile row formed at any one or more positions by the processing yarn 1 is higher than the lightness of the pile formed by the processing yarn 2. The present invention provides a tile carpet characterized in that a pattern is given by making it high in color. That is, from a pile formed from 1000 to 1500 dtex processed yarn 1 (hereinafter referred to as “pile 1”) and a pile formed from 2000 to 3000 dtex processed yarn 2 (hereinafter referred to as “pile 2”), By configuring the pattern, it is possible to eliminate the uncomfortable feeling of the pattern when the tile carpet is washed and pasted by the action of the pile 2. Furthermore, various designs can be pasted by flow pasting, and a design that could not be imparted at the time of construction can be imparted.

  In addition to the feature of claim 1, the invention described in claim 2 is a pile row formed from 1000 to 1500 dtex processed yarn 1 and / or a pile row formed from 2000 to 3000 dtex processed yarn 2. Is provided in a substantially straight line shape in the stitch direction. The uncomfortable feeling of the joint pattern due to the flow of the tile carpet is particularly noticeable in the case of a linear pattern, that is, a pattern formed by a pile formed by a straight tuft, but according to the present invention, the pattern is formed by a pile of straight tufts. Even in the case of tile carpets, there is no sense of discomfort in the pattern of joints due to sinking, and the design of the entire construction surface can be improved by applying various designs by allowing sinking.

  The tile carpet of the present invention gives a pattern to the pile 1 made of processed yarn 1 of 1000 to 1500 dtex and the pile 2 made of processed yarn 2 of 2000 to 3000 dtex by making the colors of lightness different from each other. Since 1 is partially covered, it is possible to eliminate the sense of incongruity in the joint pattern in the stitch direction when the paste is applied. In particular, when the pattern imparted to the pile 1 is elongated in the stitch direction by a straight tuft, it is particularly effective for resolving the uncomfortable feeling at the joint when the paste is applied.

  Moreover, even when the paste is applied by the tile carpet of the present invention, the discomfort of the joint pattern in the stitch direction can be eliminated as described above, so that various designs can be applied using the flow paste. The degree of freedom in design as a whole carpet construction part can be improved, and the design can be remarkably improved.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a sectional view showing an example of a direction perpendicular to the stitch direction of the tile carpet of the present invention. Pile 1 (P1) and pile 2 (P2) are tufted on the base fabric 1. A secondary base fabric layer 4 is provided at a portion located substantially in the middle of the backing layer 3 provided at the lower portion of the base fabric 1.

  The base fabric 1 can use a well-known raw material, for example, a polyester nonwoven fabric, a woven fabric, a poly polo hessian woven fabric etc. are mentioned. The base fabric 1 may be coated with SBR, MBR, PVC latex, and EVA precoat agent.

As the material of the processed yarn constituting the piles 1 (P1) and 2 (P2), known fibers such as polyamide resin such as nylon, polyester resin, polypropylene resin, polyethylene resin, and polyvinyl alcohol resin can be used.

  As the material of the processed yarn constituting the pile 1 (P1), known fibers such as polyamide resin such as nylon, polyester resin, polypropylene resin, polyethylene resin, and polyvinyl alcohol resin can be used. The pile 1 (P1) uses 1000 to 1500 dtex processed yarn. The processed yarn of the pile 1 (P1) preferably has a thickness of 1000 to 1500 dtex from the viewpoint of processability and designability, and if it is less than 1000 dtex, it becomes difficult to tuft and the processability is lowered. On the other hand, if the thickness of the processed yarn of the pile 1 (P1) exceeds 1500 dtex, the pile 1 (P1) cannot be sufficiently covered with the pile 2 (P2), which is not preferable in terms of pattern formation. .

In addition, the processed yarn can be formed by a twisted yarn obtained by twisting together different types of raw material yarns or a mixed yarn obtained by converging multi-filaments of two or more colors without using a twisted yarn. By using the mixed fiber, it is possible to improve variations in designability. Further, a single processed yarn processed to be tuftable can be used, and by using the processed yarn, brightness or color contrast is increased and a more prominent pattern can be expressed.

Further, in the pile 1 (P1), the material, form, etc. of the processed yarn constituting the pile 1 (P1) can be arbitrarily selected by a piece of tile carpet depending on the pattern to be applied or the functionality. Good.

The height H1 of the pile 1 (P1) from the surface of the base fabric 1 is preferably 4 to 6 mm. When H1 is less than 4 mm, there may be a problem that the gap is conspicuous at the joint when tile carpets are brought together. On the other hand, when H1 exceeds 6 mm, the pile is made up of loop piles. Since the loop is cut when punching into the tile carpet, it is not preferable from the viewpoint that cut pile-like fuzz generated at the end of the tile carpet may occur.

  As the material of the processed yarn constituting the pile 2 (P2), a known fiber such as a polyamide resin such as nylon, a polyester resin, a polypropylene resin, a polyethylene resin, or a polyvinyl alcohol resin can be used as in the case of the pile 1 (P1). However, the fibers are not necessarily made of the same type of resin as the pile 1 (P1), and may be made of a different type of resin from the pile 1 (P1).

In addition, the pile 2 (P2) uses a processed yarn of 2000 to 3000 dtex. The processed yarn of Pile 2 (P2) is in an appropriate balance with Pile 1 (P1), can exhibit excellent design properties, and can suppress the total weight of the pile, which is 2000 to 3000 dtex in terms of cost. When the thickness is less than 2000 dtex, the balance with the pile 1 (P1) is deteriorated, and the pile 1 (P1) becomes too conspicuous, resulting in a problem that the design is deteriorated. On the other hand, if the thickness of the processed yarn of the pile 1 (P1) exceeds 3000 dtex, it is difficult to sufficiently cover the pile 2 (P2), and there is a possibility that an uncomfortable feeling at the joint portion may occur. It is not preferable.

As for the form of the processed yarn constituting the pile 2 (P2), similarly to the pile 1 (P1), a twisted yarn, a mixed yarn, and a yarn obtained by processing one filament can be used. Further, the form of the pile 2 (P1) is not necessarily the same as the form of the pile 1 (P1), and may be different. In the pile 2 (P2), similarly to the pile 1 (P1), the material and form of the processed yarn can be appropriately selected depending on the portion of one tile carpet.

In the tile carpet of the present invention, pile 1 (P1) and pile 2 (P2) are formed by tufting a processed yarn 1 of 1000 to 1500 dtex and a processed yarn 2 of 2000 to 3000 dtex on the base fabric 1, respectively. The method of tufting the processed yarns 1 and 2 is not particularly limited, and a straight tuft may be used, or a tuft by needle shift may be used. In general, when a pile is formed by straight tufts, pattern irregularities are conspicuous in joints in the stitch direction when a tile carpet is washed and pasted. The reason for this is that the tile carpet is caused by a shift of a cut portion when it is processed into a tile shape by punching a long carpet that becomes a tile carpet in the manufacturing process. That is, in the punching process, a square is punched almost accurately with a die set blade, but it is practically impossible to cut between the piles accurately due to slight misalignment when a long carpet is transferred to the punching machine. It is possible, and the deviation of the cut portion is inevitable.

For example, when punching into a tile carpet, it often happens that the pile is cut from the top of the pile to the adjacent pile. In such a case, when the tile carpet is abutted parallel to the stitch direction, the joints are noticeable when forming joints when the parts cut on the pile and the parts cut between the piles are washed and pasted. A feeling of strangeness in appearance such as a change in pattern feeling will occur. Therefore, the effect of eliminating the sense of incongruity of the joint of the tile carpet of the present invention is remarkable when a pile is formed by a straight tuft. In addition, about the form of the pile of this invention tile carpet, both the pile 1 and the pile 2 may be cut pile, and a loop pile may be sufficient as them.

  Since the lightness of the processed yarn 1 constituting the pile 1 (P1) of the tile carpet of the present invention is higher than the lightness of the processed yarn 2 constituting the pile 2 (P2), naturally the lightness of the pile 1 (P1). Is higher than the lightness of pile 2 (P2).

In the tile carpet of the present invention, a pattern is formed by the lightness difference of the pile 1 (P1) and the pile 2 (P2) derived from the lightness difference between the processed yarns 1 and 2, the height H1 of the pile 1, and the height H2 of the pile 2. Has been granted. In the tile carpet of the present invention, the pattern shape is formed by adjusting the height H1 of the pile 1 and the height H2 of the pile 2. That is, the difference between the height H1 of the pile 1 and the height H2 of the pile 2 is formed in the range of 1.0 to 3.0 mm in the portion represented as a pattern, while the portion H1 and The difference in height of H2 is set to 3.5 mm or more, more preferably 4 mm or more. In the former case, the pile 1 (P1) is visually recognized from between the piles 2 (P2), and in the latter case, the pile 1 (P1) is hidden between the piles 2 (P2). It is not visually recognized. That is, by appropriately adjusting and combining the difference between the height H1 of the pile 1 and the height H2 of the pile 2, the shape of the pattern is formed, and by combining lightness, and further, lightness and color as appropriate, Various colors can be expressed. Therefore, the tile carpet of the present invention is provided with a pattern in which the shape, color and the like are formed by the difference in height between H1 and H2, the difference in brightness, and the color. In the tile carpet of the present invention, the lightness of the pile 1 (P1) may be higher than the lightness of the pile 2 (P2), and the color is not particularly limited. The larger the difference in lightness between the pile 1 (P1) and the pile 2 (P2), the more noticeable the discomfort of the joint pattern in the stitch direction of the tile carpet when it is pasted to the tile carpet. The effect of eliminating the uncomfortable feeling at the joints of the tile carpet of the present invention is extremely useful.

  The heights of the pile 1 (P1) and the pile 2 (P2) are as described above. However, the height H1 of the pile 1 (P1) is lower than the height H2 of the pile 2 (P2). It is necessary from the viewpoint that the pile 2 (P2) covers a part of the pile 1 (P1) when the piles 1 (P1) forming the pattern at the joint portion are adjacent to each other. Specifically, in the pattern portion, the difference between H1 and H2 is preferably about 1 to 3 mm. When the difference between H1 and H2 is less than 1 mm, when the piles 1 (P1) that form patterns at the joint portions are adjacent to each other, the pile 2 (P2) cannot sufficiently cover the pile 1 (P1). If it exceeds 3 mm, pile 1 (P1) is covered with pile 2 (P2), so the outline of the pattern is not clearly reproduced and the appearance is ambiguous Because there is. Furthermore, when the difference between H1 and H2 is 4 mm or more, the pile 1 (P1) is completely covered with the pile 2 (P2), and the appearance pattern cannot be visually recognized. It is because it becomes impossible to do.

  The backing layer can be composed of a material that constitutes a known backing layer. For example, a PVC base made of a resin paste vinyl chloride resin, an EVA base made of a vinyl chloride-vinyl acetate copolymer, and an APP made of an APP resin. A PUR base composed of a base, an isocyanate, a polyol and the like can be used. Further, from the standpoint of physical property stability such as dimensional stability, a conventionally used glass mat and polyester woven fabric or cloth woven fabric may be provided at a substantially intermediate position of the backing layer.

  FIG. 2 is a partial cross-sectional view showing an example of a joint portion in the stitch direction when a conventional tile carpet is poured and pasted. On the surface of the tile carpet, dark color piles 21 and light color piles 22 are alternately planted in a straight line in the stitch direction on a base fabric (not shown in the drawing), and a backing layer is provided on the base fabric. As a result of punching the tile carpet shown in FIG. 2 into tiles, the ends having light-colored piles form a joint J2.

An actual tile carpet does not stand up to the tip of the pile, and the portion near the tip of the pile faces in various directions. Accordingly, the tile carpet laid on the site is also visually observed in the above-described state, and as shown in FIG. 2, the tile carpet surface is visually recognized as a pale color pile, that is, a pale color, with a width of W21, and at the joint portion J2. It will be visually recognized by the width of W22. Since the width W22 of the light-colored pile of the joint portion J2 is visually recognized as being wider than the width W21 of the light-colored pile of the tile carpet, the pattern of the joint portion J2 is uncomfortable.

  On the other hand, FIG. 3 shows a partial cross-sectional view of an example of a joint portion in the stitch direction when the tile carpet of the present invention is cast and pasted. On the surface of the tile carpet, one row of dark-colored piles 32 and two rows of light-colored piles 31 are alternately planted in a straight line in the stitch direction on a base fabric 33, and a backing layer is provided on the base fabric. . As in the example of FIG. 2, the tile carpet is punched into a tile shape, and as a result, ends having light-colored piles form a joint J2.

The light-colored pile 31 corresponds to the pile 1 of the tile carpet of the present invention, and the dark-colored pile 32 corresponds to the pile 2 of the tile carpet of the present invention. In general, the carpet pile has a property of spreading upward from the planted portion of the base fabric, and this does not matter whether the pile is in the form of a cut pile or a loop pile. Due to the nature of the pile shape of the carpet, even if there is an interval between the pile planting portions, almost no gap is observed in the portion of the pile exposed on the carpet surface.

By the way, in the tile carpet of the present invention, the above-mentioned property of the carpet pile is utilized, thereby producing an effect of reducing the uncomfortable feeling of the joint portion when the paste is applied. That is, as shown as an example in FIG. 3, since the pile height of the light-colored pile 31 is lower than that of the dark-colored pile 32, the portion near the tip of the dark-colored pile spreads. As a result, it will be visually recognized by the width of W31 and W32 as the pale color pile in the joint part J3, and even if it is the joint part J3 which the edge part which has a pale color pile contact | abuts as shown in FIG. A sense of incongruity is hardly felt.

  Moreover, in the tile carpet of the present invention, the reason why the pile 1 is required to have a higher brightness than the pile 2 is that the portion not covered with the dark-colored pile has the piles 1 and 2 in addition to the three-dimensional design. This is also because a shadow due to the pile 2 is formed in the portion of the pile 1 due to the difference, and the uncomfortable feeling of the joint portion is made less noticeable.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited to the following examples.
(Example)
A pile was formed by straight tufting a processed yarn as shown in Table 1 on a base fabric (trade name: manufactured by Marix Unitika Ltd.). A net made of a polyester resin of about 3 mm PVC is provided as a backing layer of the green machine on which the pile is formed, and a net made of a polyester resin (trade name: Kurenet-Kurashiki Spinning Co., Ltd. ) And a glass nonwoven fabric, and then punched into a 500 mm square by a punching machine to obtain a tile carpet of the present invention. Furthermore, the tile carpet of the present invention is all cast and spread in a standard light source room of about 30 m ^{2, and} a light source of standard illuminant (high color rendering, natural daylight white, Ra99, color temperature 5000K) has a discomfort in the joint part under 1500LX. The degree was judged visually.

(Comparative example)
Except for producing tile carpets under various conditions such as processed yarns as shown in Table 1, all were produced in the same manner as in the Examples, and the degree of discomfort in the joints was visually evaluated.
(Evaluation methods)
Twenty people visually evaluated and evaluated in four stages (1 to 4 points), and the average value was rounded off to give 1 point ×, 2 points Δ, 3 points ○, 4 points 点.
A: The joint part is not visually recognized and there is no sense of incongruity.
○: The joint portion is slightly visually recognized but hardly noticeable and uncomfortable.
Δ: The joint part is visually recognized and there is a slight sense of incongruity.
X: A joint part is visually recognized and there is a sense of incongruity.

  From Example 1, the processed yarn 1 constituting the pile 1 is 1000 dtex, and the processed yarn constituting the pile 2 is 2000 dtex. In this case, the joint portion is slightly visually recognized but hardly noticeable, and there is no sense of discomfort as a whole. On the other hand, when the processed yarn 1 constituting the pile 1 is 720 dtex as compared with Comparative Example 1, the joint portion is visually recognized even if other invention specific matters are provided, and there is a slight discomfort. Further, according to Comparative Example 3, even when the processed yarn 1 is 720 dtex and the processed yarn 2 is 1440 dtex, the pile 2 cannot sufficiently cover the visible portion of the pile 1, so that the joint portion has a slightly uncomfortable feeling. It is thought that it will occur.

Further, it can be seen from Example 2 and Comparative Example 2 that when the processed yarn 2 constituting the pile 2 exceeds 3000 dtex, the joint part is uncomfortable. This is probably because the processed yarn 2 is thick and the pile 2 does not have sufficient “bending” to cover the pile 1.

Further, it can be seen from Example 3 and Comparative Example 6 that when the processed yarn 2 constituting the pile 2 is less than 2000 dtex, the joint portion is noticeable and uncomfortable. The reason for this is that the pile 2 made of the processed yarn 2 of less than 2000 dtex does not have a sufficient pile thickness so as to sufficiently cover the extra visible portion of the pile 1, so there is a slight sense of incongruity at the joint. It is thought that it will occur.

In Comparative Example 3, when the processed yarns 1 and 2 constituting the piles 1 and 2 are less than 1000 dtex and less than 2000 dtex, respectively, Comparative Examples 4 and 5 are used when the processed yarn 1 constituting the pile 1 exceeds 2000 dtex. No. 2 indicates that the joint portion is conspicuous because the extra visible portion of the pile 1 cannot be sufficiently covered.
