Description

  The present invention relates to a pile yarn for carpet and a carpet. More specifically, the present invention can reduce fouling due to play hair, and can have a soft touch and a smooth surface. The present invention relates to a carpet capable of maintaining an excellent texture such as texture over a long period of time, and a pile yarn having excellent crimp durability used therefor.

  Carpet enhances the aesthetic effect of the room and creates a beautiful atmosphere by synergistic effects with other interior materials such as furniture, wallpaper, curtains, etc. In addition, it expresses the desired space image in the room and creates a favorable atmosphere. Influential. For this reason, the carpet is required to have various characteristics such as color, pattern, texture, and volume according to the image of the space. In particular, as a trend in recent years, a carpet having a soft texture is preferred because the skin of a resident or the like may directly touch the carpet.

  2. Description of the Related Art Conventionally, carpets that use spun yarn such as cotton and polyester short fibers have been distributed as the above-mentioned carpet with a soft texture. However, carpets using these spun yarns often generate loose hair, and dirt due to dust or the like caused by the loose hair is easily noticeable. There was a problem of inferiority.

  Therefore, suede-weaving knitted fabric using filament yarn made of ultra-fine polyester fibers has been proposed as a carpet with soft texture that prevents the occurrence of loose hair by using continuous fiber yarn (filament yarn) (for example, Patent Document 1, hereinafter referred to as Prior Art 1). In this prior art 1, a copolyester fiber having a single yarn fineness of 1.5 dtex or less is used, and a false twist crimping process is preferably applied to this copolyester fiber in order to obtain an excellent volume feeling and soft texture. Has been given. However, even if the texture is soft, the carpet formed using the pile yarn made of this ultra fine polyester fiber has a soft touch and smooth surface like the peach surface, which is called peach touch. I can't get it. In addition, the crimping durability of the crimped yarn is inferior with polyester fiber, so the carpet using this yarn loses its volume feeling and soft texture at an early stage, and the texture of the carpet is lowered. There are also problems such as inferiority.

  Further, as a pile yarn, a tile carpet using an ultra-fine, original polylactic acid crimped yarn having a single yarn fineness of 2.5 to 25 dtex has been proposed (see, for example, Patent Document 2, hereinafter, Prior Art 2). That said.) This prior art 2 uses a plant-derived material and appealed for its kindness to the global environment. The pile yarn made of this original polylactic acid crimped yarn is also soft to the touch such as peach touch. And you can't get a smooth surface. In addition, the pile yarn of this prior art 2 has a very low rebound feeling, requires a non-woven fabric having a cushioning property for the backing layer, and is inferior in the crimp durability of this pile yarn. There was a problem that the sense of volume and soft texture of the carpet disappeared.

  On the other hand, as a carpet having excellent durability, a polyamide multifilament crimped yarn (so-called nylon BCF (Bulked Continuous Filament)) having a single yarn fineness of 3.0 to 7.0 dtex is twisted at 200 to 2000 T / m. A product using a twisted crimped yarn as a pile yarn has been proposed (see, for example, Patent Document 3, hereinafter referred to as Prior Art 3). Although the pile yarn used in this prior art 3 has excellent crimp durability, it has a single yarn fineness of 3 dtex or more and is highly twisted, so that it has high rigidity and lacks flexibility. Therefore, the carpet of this prior art 3 also has a problem that it cannot obtain a soft touch and a smooth surface like peach touch, and it is not easy to sufficiently enhance the soft texture.

  The technical problem of the present invention is to solve the above-mentioned problems, reduce fouling caused by play hair, can have a soft touch and a smooth surface, and has an excellent volume feeling and soft texture. It is to provide a carpet capable of maintaining an excellent texture for a long period of time and a pile yarn having excellent crimp durability used for the carpet.

In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 6 showing an embodiment of the present invention.
That is, the present invention 1 relates to a carpet pile yarn, including a loop yarn having a core-sheath structure, wherein the loop yarn includes a core yarn and a sheath yarn composed of a filament yarn, and a loop protruding at least 1.5 mm from the surface of the yarn. The number of fluff is 30 pieces / m or more, and the total fineness of the entire pile yarn is 990 decitex or more.

  The present invention 2 relates to a carpet, characterized in that the pile yarn for carpet of the present invention 1 is used in 60% or more of the total number of pile yarns tufted to the base fabric.

Here, the loop yarn having the above-described core-sheath structure has a large number of irregular loops on the surface of the yarn, which is obtained, for example, by spraying compressed air or the like on the yarn in a nozzle and performing fluid turbulence treatment. It is a thread.
The yarn surface of the loop yarn is a photoelectric type fluff measuring machine (Hairness Counter DT-104, manufactured by Toray Engineering Co., Ltd.) placed on the side of the loop yarn when the loop yarn is run in the length direction. ), When the number of loops is measured while shifting from a position close to the loop yarn by 0.01 mm, and a loop distribution graph is created, it is defined by the position of the photoelectric tube sensor that is the peak value of the number of loops. .

  The carpet pile yarn of the present invention 1 includes a loop yarn having a core-sheath structure, and the loop yarn is composed of filament yarns for both the core yarn and the sheath yarn, so that occurrence of single yarn breakage is suppressed. In the carpet using this, the occurrence of play hair is suppressed and fouling due to play hair is prevented.

  In addition, since the loop yarn has a number of loop fluffs of 30 mm / m or more protruding from the surface of the yarn by 1.5 mm or more, the pile yarn of the present invention 1 is a so-called peach-touch pile hair on the surface of the peach. Such as a carpet with a soft touch and a smooth surface. When the number of loop fluffs protruding from the surface of the yarn of the loop yarn by 1.5 mm or more is less than 30 / m, it is not easy to realize the above peach touch texture as a processed yarn, and it is not different from a normal carpet. It is easy to become a thing.

  The loop yarn preferably has a number of fluffs protruding from the yarn surface of 5.0 mm or more and less than 5 / m. If the number of loop fluffs protruding from the yarn surface by 5.0 mm or more is 5 pieces / m or more, in the tufting process, adjacent yarns may be entangled with each other to induce thread breakage and significantly deteriorate high-order passability. Because there is.

  Since the total fineness of the entire pile yarn of the pile yarn for carpet of the present invention 1 is larger than 990 dtex, the carpet formed of this pile yarn can have an appropriate repulsive force.

  When the core yarn is made of nylon BCF, which is a continuous fiber, the loop yarn can exhibit excellent crimpability and crimp durability, and a carpet using the yarn can be used for a long time. It is more preferable because it has moderate softness and resilience.

  The core yarn is not limited to a specific thickness, but if the fineness is larger than 660 dtex, the bending rigidity of the loop yarn increases, and the carpet formed using this has a firmness and stiffness. It is preferable because the resilience can be emphasized.

  The degree of crimp when the carpet pile yarn is crimped is not limited to a specific characteristic value, but the expansion / contraction elongation ratio of the core yarn after boiling water treatment is 10 to 40%. The carpet is preferable because it has an appropriate resilience.

  The carpet of the present invention 2 is tufted to the base fabric using 60% or more of the pile yarn for carpet of the present invention 1, and thus has a soft touch of peach touch and a soft and smooth texture. In the carpet of the present invention 2, it is more preferable that 80% or more of the pile yarn of the present invention 1 is used for the pile yarn tufted to the base fabric because it can have a softer touch and a soft and smooth texture. It is more preferable that all are constituted by the pile yarn of the present invention 1.

Since the present invention is configured and operates as described above, the following effects can be obtained.
(1) Since both the core yarn and the sheath yarn are made of filament yarn, and the occurrence of single yarn breakage is suppressed, the carpet using this is suppressed from the occurrence of play hair, and is caused by play hair. Is prevented.
(2) Since the loop yarn included in the pile yarn has 30 / m or more of the number of loop fluffs protruding from the yarn surface by 1.5 mm or more, the carpet using the pile yarn containing this loop yarn is peach It can be made into an excellent texture with a soft touch and a smooth surface, with a peach-touch like a velvety surface.
(3) Since the pile yarn has a total fineness of 900 dtex or more, the carpet formed using this pile yarn can have a moderate rebound.

It is a schematic diagram which shows an example of the pile yarn for carpets of this invention. It is a schematic diagram which shows another example of the pile yarn for carpets of this invention. It is a schematic diagram which shows another example of the pile yarn for carpets of this invention. It is a schematic diagram which shows the manufacturing process of a loop yarn. It is a schematic diagram which shows the process of measuring the number of loops. It is a schematic diagram which shows an example of loop number distribution protruded from the yarn surface.

  The carpet pile yarn of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic side view showing an example of a pile yarn for carpet according to the present invention. The carpet pile yarn (1) includes a loop yarn (2) having a core-sheath structure, and in this example, the pile yarn (1) is composed of one untwisted loop yarn (2). . In the loop yarn (2), a sheath yarn (4) made of a filament yarn is arranged around a core yarn (3) made of a filament yarn. The core yarn (3) and the sheath yarn (4) form a loop (5) protruding from the yarn surface of the loop yarn (2) while being intermittently entangled in the longitudinal direction of the yarn.

  The loop yarn included in the pile yarn for carpet of the present invention has 30 loops / m or more protruding from the yarn surface by 1.5 mm or more, thereby realizing a peach skin-like texture when the carpet is formed. can do. On the other hand, when the number of loops protruding 5.0 mm or more is 5 / m or more, when the pile yarn is released from the yarn package, the loops are entangled with each other, and the so-called fastener phenomenon is released due to abnormal tension or yarn breakage. May occur. Therefore, the above loop yarn has 30 loops / m or more protruding from the yarn surface by 1.5 mm or more, but it is preferable that the loop protruding 5.0 mm or more is in the range of less than 5 loops / m. Of course, the loop protruding 5.0 mm or more may not exist at all.

  The loop yarn included in the carpet pile yarn of the present invention may be a single yarn, a plurality of loop yarns, or a composite yarn with other yarns. The total fineness as a whole is 990 dtex or more. If the total fineness is excessively small, when the carpet is formed, the feeling of resilience is lacking and there is a feeling of bottoming. However, if the total fineness is 990 decitex or more, the formed carpet should have a moderate resilience. Can do. However, if the total fineness exceeds 4400 dtex, there is a possibility that the softness of the carpet may be lost. Therefore, the total fineness of the loop yarn is preferably 4400 dtex or less.

  The carpet pile yarn of the present invention is composed of filament yarns for both the core yarn and the sheath yarn, and the occurrence of single yarn breakage is suppressed. Staining caused by hair can be prevented.

  Although it does not specifically limit as a filament yarn used for the core yarn of the pile yarn for carpets of this invention, It is preferable that it is nylon BCF. The resin constituting the nylon BCF is not limited to a specific polyamide. Specifically, for example, polycaproamide (nylon 6) or polyhexamethylene adipamide (nylon 66) is used, and the effects of the present invention are not impaired. It may be a polyamide copolymer containing a copolymer component in a range. Furthermore, it may be a polyamide to which a copolymer component is added for the purpose of improving the yarn-making property and higher-order processability, or other particles such as pigments. Specific examples of the copolymer component include ε-caproamide, tetramethylene adipamide, hexamethylene sebacamide, tetramethylene isophthalamide, tetramethylene terephthalamide, and xylylene phthalamide. The pigment may be either organic or inorganic, and generally, carbon black, bengara, or phthalocyanine pigments are preferably used.

  The filament yarn used for the core yarn of the carpet pile yarn of the present invention is not limited to one having a specific thickness, but preferably has a fineness of 660 to 3300 dtex. The fineness of the core yarn affects the bending rigidity of the pile yarn. When the carpet is formed, if it is less than 660 dtex, hair fall tends to occur and there is no rebound, and if it exceeds 3300 dtex, the texture is hard. This is undesirable.

  After being tufted, the pile yarn for carpet according to the present invention is crimped by receiving heat in the dyeing process. Among pile yarns, the degree of crimping when the core yarns are crimped is preferably 10 to 40% of the stretch / extension rate after boiling water treatment. If the stretch / elongation rate after boiling water treatment is less than 10%, the pile yarn will be weakly crimped and thinned, and there is a possibility that the carpet may fall down or have a feeling of thinness. On the other hand, when the expansion / contraction elongation ratio after the boiling water treatment exceeds 40%, the texture of the carpet becomes hard and a desired soft texture cannot be obtained.

  The sheath yarn of the carpet pile yarn of the present invention is preferably a nylon yarn from the viewpoint of enhancing the same color property as the core yarn and the softness of the texture.

  The single fiber fineness of the sheath yarn of the carpet pile yarn of the present invention is preferably 0.8 to 3.0 dtex from the viewpoint of realizing the softness of the loop fluff single yarn and the peach skin tone.

  In the embodiment shown in FIG. 1, the carpet pile yarn of the present invention has been described with respect to a case where the carpet pile yarn is composed of one untwisted loop yarn. However, the pile yarn of the present invention may be used by twisting the loop yarn (2) as shown in FIG. 2, for example, and a plurality of loop yarns (2) as shown in FIG. Alternatively, twisting may be performed by combining twisting yarns of different materials or combining yarns other than loop yarns and loop yarns. The method of twisting may be selected as appropriate, such as single twisting and various twisting.

Next, the manufacturing method of the loop yarn contained in the pile yarn of this invention is demonstrated using FIG. 1 and FIG.
The core yarn (3) and the sheath yarn (4) are supplied into the fluid turbulent nozzle (8) in an overfeed state by feed rollers (6, 7), respectively. Here, in order to form the loop (5) while the sheath yarn (4) is arranged around the core yarn (3), the feed speed of the sheath yarn feed roller (7) is set to Needless to say, it is essential to be faster than the feeding speed of the roller (6).

In order to improve the entanglement performance in the fluid turbulent nozzle (8), a water application guide (9) disposed upstream of the fluid turbulent nozzle (8) is used for the core yarn (3). It is preferable to apply water in advance.
As a result of the fluid turbulent flow treatment in the fluid turbulent nozzle (8), the sheath yarn (4) over-feeded from the core yarn (3) forms many fine loops (5) while entangled. Loop yarn (2). The loop yarn (2) is wound around the package (12) by the winder (11) through the delivery roller (10).

Next, the carpet of the present invention will be described.
In the carpet of the present invention, 60% or more of the above-mentioned pile yarn of the present invention is used in the entire pile yarn, and this makes it possible to make a carpet with a soft and peach skin-like texture. It is preferable to use 80% or more of the pile yarn of the invention. Of course, when 100% of the pile yarn of the present invention is used, the soft and smooth texture can be further emphasized.
