Description

  The present invention relates to a raised fabric having a ground tissue portion and a raised portion. More particularly, a raised fabric having a ground tissue portion and a raised portion made of raised yarns woven or woven into the ground tissue portion, wherein the density of the raised yarn is high and the raised length is short. The present invention relates to a dense ultrashort upholstery fabric that exhibits a high-grade appearance and a smooth touch similar to the upholstery fabric, a manufacturing method thereof, and a car seat member.

  Conventionally, a napped fabric composed of a napped portion and a ground tissue portion has been used in a wide range of fields because of its excellent appearance and surface touch. Among them, the flocked raised fabric obtained by electric flocking, which is also called flocking, can increase the density of the raised yarn (densely) and shorten the raised length, so that it has a fine appearance and a high-class appearance derived from the ultrashort raised length. It has a smooth touch and is widely used as a luxury product in interior fields such as chair upholstery, vehicle interior materials field, and clothing field using materials such as polyester fiber and nylon fiber (for example, see Patent Document 1). ).

  However, when such a flocked napped fabric is used as a car seat member, the root of the napped yarn is chemically bonded to the ground tissue part. There was a problem that the yarn was pulled out of the ground tissue part.

As a method for preventing such napped yarn from coming off, Patent Document 1 proposes that the napped yarn is bundled at the root portion, but is basically subjected to chemical bonding treatment. It has not been enough to solve the problem of yarn loss.
JP-A-10-168893

  The present invention has been made in view of the above-described background, and an object thereof is napped having a ground tissue portion and a raised portion made of a raised yarn knitted or woven into the ground tissue portion. A dense ultrashort raised fabric that has the same high-grade appearance and smooth touch as a flocked raised fabric with a high density of raised yarns and a short raised length, and that prevents the raised yarns from coming out of the ground tissue portion, and its production It is to provide a method and a car seat member.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors have arranged a highly heat-shrinkable yarn as the raised yarn of the raised fabric, and heat-treated the raised fabric, thereby obtaining a raised fabric having an extremely short raised length. As a result, the present invention has been completed.

Thus, according to the present invention, “a raised fabric having a ground tissue portion made of an organic fiber yarn and having a knitted structure and a raised portion made of a raised yarn knitted in the ground tissue portion, wherein the raised fabric is The napped yarn density is 40000 to 300,000 dtex / cm 2 , the single yarn fineness of the napped yarn is in the range of 0.1 to 1.2 dtex, the napped length is in the range of 0.20 to 0.80 mm, and the napped yarn is A dense ultrashort upholstery fabric characterized in that it is a non-crimped upholstery yarn "is provided.

  In that case, it is preferable that the napping angle of the napped yarn is in the range of 70 to 90 degrees. Such napped yarn is preferably a polyester fiber yarn in terms of recyclability. It is preferable that the organic fiber yarn forming the texture portion is also a polyester fiber yarn from the viewpoint of recyclability.

The above-mentioned dense ultrashort upright blanket is composed of “a ground tissue portion made of organic fiber yarns and having a knitted structure, and a single yarn fineness of 0.1 to 1.2 dtex and hot water woven into the ground tissue portion. After knitting a raised fabric having a raised portion composed of a non-crimped raised yarn having a shrinkage rate of 20% or more, the raised fabric is thermally contracted by subjecting the raised fabric to heat treatment, thereby increasing the raised yarn density of the raised portion. 40000~300000dtex / cm 2, the manufacturing method of the dense ultrashort napped fabric according to nap length of the standing yarn to claim 1 in the range of 0.20~0.80Mm. "by obtained.

  At that time, when the yarn having a hot water shrinkage rate of 20% or more and / or the false twist crimped yarn having a crimp rate of 30% or more is used as the organic fiber yarn forming the ground texture portion, the napped portion The above napped yarn density is preferable because it is easy to obtain.

  In addition, according to the present invention, there is provided a car seat member using the dense ultrashort blanket.

  According to the present invention, there is a raised fabric having a ground tissue portion and a raised portion made of a raised yarn knitted or woven into the ground tissue portion, wherein the density of the raised yarn is high and the raised length is high. A dense ultrashort blanket having a high-grade appearance and a smooth touch similar to that of a short flocked blanket, and in which the napped yarn is difficult to escape from the ground tissue portion, a method for producing the same, and a car seat using such a dense ultrashort blanket A member is provided.

  The raised fabric of the present invention has a ground tissue part (A) having a knitted fabric structure composed of organic fiber yarns, and is knitted or woven into the ground texture part, and at least one surface side from the ground texture part. And a napped portion (B) made up of a plurality of napped yarns (cut pile). In the napped fabric of the present invention, the napped yarn is knitted or woven into the ground tissue portion, so that it has a feature that the napped yarn is less likely to come out of the ground tissue portion compared to the conventional flocked napped fabric. .

  The raised yarn has a single yarn fineness of 0.1 to 1.2 dtex (preferably 0.2 to 0.6 dtex), and a raised length of 0.20 to 0.80 mm (preferably 0.30 to 0.70 mm). ) Must be in the range. When the single yarn fineness is less than 0.1 dtex, it is difficult to maintain the raised state, and there is a possibility that problems such as broken yarn and reduced dyeing fastness due to friction may occur. On the contrary, when the single yarn fineness is larger than 1.2 dtex, it is difficult to provide a smooth touch, which is not preferable. On the other hand, if the above-mentioned nap length is less than 0.20 mm, the sense of sheerness of the ground texture portion increases, so that the appearance is frustrating and the high-grade appearance is impaired. On the other hand, if the length of the nap is larger than 0.80 mm, it is difficult to maintain the upright state of the napped yarn, which is not preferable because the high-grade appearance is deteriorated. In the present invention, the nap length is the distance of L / sin α shown in FIG.

The napped yarn density of the napped portion formed by such napped yarns needs to be in the range of 40,000 to 300,000 dtex / cm 2 (preferably 50,000 to 150,000 dtex / cm 2 , particularly preferably 100,000 to 140000 dtex / cm 2 ). When the napped yarn density is less than 40,000 dtex / cm 2, the napped yarn is liable to fall down, which is not preferable because a high-grade appearance and a smooth touch similar to those of the flocked napped fabric as the main object of the present invention cannot be obtained. Such a hair fall phenomenon is remarkable when the dense ultrashort blank fabric of the present invention is used as a car seat member under severe use conditions. On the contrary, if the napped yarn density is larger than 300000 dtex / cm 2 , not only the texture is cured but also the production cost is increased, which is not preferable. In addition, the above-mentioned napped portion having the napped yarn density can be easily obtained by using a high heat shrinkage yarn or false twist crimped yarn as described later.

  The napping angle of the napped yarn is preferably in the range of 70 to 90 degrees in order to obtain a high-grade appearance and a smooth touch similar to the flocked napped fabric. When the napped angle is smaller than 70 degrees, the napped portion has directionality, and the intended high-grade appearance and smooth touch may not be obtained. Such a napped angle can be easily obtained by knitting and weaving a napped fabric so that the napped yarn density falls within the above range, and then, if necessary, erecting the napped yarn with a normal rotary heat brush having a straight needle cloth on the surface. Is obtained. The raised angle is an angle α formed by the raised yarn shown in FIG. 1 and the ground tissue portion, and the right angle is 90 degrees.

  The type of fiber forming the napped yarn is not particularly limited. Cotton, wool, hemp, viscose rayon fiber, polyester fiber, polyetherester fiber, acrylic fiber, nylon fiber, polyolefin fiber, cellulose acetate fiber, aramid fiber Ordinary fibers such as Of these, polyester fibers are particularly preferable from the viewpoint of recyclability. The polyester fiber is produced from a dicarboxylic acid component and a diglycol component. As the dicarboxylic acid component, terephthalic acid is preferably used mainly, and as the diglycol component, it is preferable to use one or more alkylene glycols selected from ethylene glycol, trimethylene glycol and tetramethylene glycol. Moreover, the polyester resin may contain a third component in addition to the dicarboxylic acid component and the glycol component. Examples of the third component include cationic dye-dyable anion components such as sodium sulfoisophthalic acid; dicarboxylic acids other than terephthalic acid, such as isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid; and glycol compounds other than alkylene glycol. For example, one or more of diethylene glycol, polyethylene glycol, bisphenol A, and bisphenol sulfone can be used. Further, it may be a biodegradable polyester fiber such as polylactic acid.

  In the resin forming the fiber, a matting agent (titanium dioxide), a fine pore forming agent (organic sulfonic acid metal salt), an anti-coloring agent, a heat stabilizer, a flame retardant (antimony trioxide), if necessary. , A fluorescent brightening agent, a coloring pigment, an antistatic agent (sulfonic acid metal salt), a hygroscopic agent (polyoxyalkylene glycol), an antibacterial agent, and other inorganic particles may be contained.

  The shape of the raised yarn may be a non-crimped raised yarn, a false twist crimping method, a mechanical crimping method, or a crimped standing obtained by heat-treating a Cybyside type latent crimpable composite fiber. A wool yarn may be used and is not particularly limited, but is preferably a non-crimped yarn for obtaining a high-quality appearance.

  There are no particular limitations on the single fiber cross-sectional shape of the napped yarn, and it may be a regular circular cross section, a triangular, flat, constricted flat, cross, hexagonal, or hollow cross section.

  In the dense ultrashort blanket of the present invention, the ground texture portion is composed of organic fiber yarns and has a knitted texture. As a fiber which comprises this organic fiber yarn, the thing similar to the fiber illustrated as an example for the above-mentioned napped yarn may be sufficient. In particular, polyester fiber is preferable in terms of recyclability.

  Although the form of the organic fiber yarn constituting the ground tissue part is not particularly limited, it is preferably a long fiber (multifilament yarn). The single fiber fineness and the total fineness of the organic fiber yarn are preferably a single yarn fiber fineness of 0.5 to 5.0 dtex and a total fineness of 30 to 300 dtex without impairing the texture of the fabric. The cross-sectional shape of the single yarn fiber is not limited, and may be a triangular, flat, constricted flat, cross-shaped, hexagonal, or hollow cross-sectional shape in addition to a normal circular cross-section. Furthermore, such organic fiber yarns include false twisted crimped yarns, composite yarns obtained by subjecting two or more types of constituent yarns to air-mixing processing or composite false twisting processing, an elastic yarn in the core portion, and a non-woven fabric in the sheath portion. It may be a covering yarn on which an elastic yarn is located.

The dense ultrashort blanket of the present invention can be easily obtained, for example, by the following production method.
First, a yarn composed of the above-mentioned fibers having a single yarn fineness of 0.1 to 1.2 dtex (preferably 0.2 to 0.6 dtex) as a yarn for napped yarn, and an organic fiber yarn for a textured portion described above. The raised fabric is knitted and woven using yarns made of the above fibers.

  At that time, it is important that the yarn for napped yarn has a hot water shrinkage (BWS) of 20% or more (preferably 22 to 40%). By using the yarn having a large hot water shrinkage rate as the yarn for napped yarn, the napped yarn can be thermally contracted by heat treatment described later, and the napped length is as short as 0.20 to 0.80 mm. Obtainable. As the yarn having such a high hot water shrinkage rate, for example, the following polyester filament yarn is preferably exemplified. That is, in addition to the usual dicarboxylic acid component and alkylene glycol component, the third component is a dicarboxylic acid such as isophthalic acid, naphthalene dicarboxylic acid, adipic acid or sebacic acid, glycols such as diethylene glycol or polyethylene glycol, bisphenol A and bisphenol sulfone. It is obtained by subjecting a copolyester resin obtained by copolymerizing at least one selected from the group consisting of the above to a normal spinning step and stretching the resulting unstretched filament yarn by a conventional method. When obtaining a polyester filament yarn having a higher hot water shrinkage rate, the obtained unstretched filament yarn is directly wound at a winding speed of about 3500 m / min without being stretched. By stretching the drawn filament yarn slightly at a temperature of 60 to 80 ° C. at a draw ratio of 1.3 to 1.5 times, a polyester filament yarn having an even higher heat shrinkage rate can be obtained.

  Further, as the organic fiber yarn for the textured portion, a yarn having a hot water shrinkage rate of 20% or more (preferably 40% or more, particularly preferably 50 to 90%) is used, or the crimp rate is 30% or more. When a normal false twisted crimped yarn (preferably 35 to 50%) is used, the fabric shrinks due to heat shrinkage due to heat treatment or the elastic recovery force of the false twisted crimped yarn. It is easy to be preferred.

  Here, in the case of obtaining a napped fabric having a knitted structure in the ground structure part, the ground structure is knitted, and a loop pile structure such as a sinker pile, a pole tricot pile, and a double raschel pile extending thereon is formed. A method of cutting the loop pile is used. The pole tricot pile is obtained by forming a pile knitted portion of a tricot knitted structure into a loop pile using a raising machine.

  On the other hand, in the case of obtaining a napped fabric having a woven fabric in the ground texture portion, weaving a warp pile fabric or a weft pile fabric and cutting the loop pile or weaving a moquette fabric and centering the pile yarn Is used.

Next, by subjecting the napped fabric to a normal dyeing finishing process, the napped yarn is thermally contracted by heat at that time, the napped yarn density of the napped portion is 40,000 to 300,000 dtex / cm 2 , and the napped length of the napped yarn is 0.00. By setting the thickness within the range of 20 to 0.80 mm, the dense ultrashort blanket of the present invention can be obtained. In the case where the dyeing finish processing is not performed, the wet heat treatment method at 80 to 130 ° C. (more preferably 100 to 110 ° C.) or the dry heat treatment method at 150 to 200 ° C. (more preferably 160 to 180 ° C.) It is preferable to heat shrink the napped yarn.

  In the napped fabric thus obtained, the napped yarn having a fine single yarn fineness of 0.1 to 1.2 dtex forms a napped portion with a high napped yarn density and an extremely short napped length. A high-grade appearance and a smooth touch similar to the flocked napped fabric are obtained. In addition, since the napped yarn is knitted or woven into the ground tissue portion, the napped yarn is less likely to fall out compared to the conventional flocked napped fabric.

  In the ground tissue portion of the dense ultrashort raised fabric of the present invention, other layers such as a known back coating layer and raised portions may be formed on the surface opposite to the raised portions. In addition, various processes that provide functions such as ordinary dye finish processing, colored printing, water repellent processing, UV shielding agent, antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, negative ion generator, etc. May be additionally applied.

[Comparative Example 2]
After knitting a knitted fabric having a tricot knitted satin structure using drawn yarn (yarn count: 84 dtex / 36) made of ordinary polyethylene terephthalate, napped yarns are put on the knitted fabric by electric flocking (flock processing). After flocking, an electrically-planted dense ultrashort raised fabric having a raised fiber density of 84000 dtex / cm 2 , a raised fiber length of 0.38 mm, and a raised fiber single fiber fineness of 0.1 dtex was obtained.
In the electric flocking dense ultrashort blanket, the amount of fallen yarn (PCO) was 4.13%, which was insufficient in terms of anti-raised yarn fallout.

[Comparative Example 3]
In Example 1, it carried out similarly to Example 1 except changing the napped yarn density of a napped part with 38000 dtex / cm < 2 >. In the obtained ultrashort raised fabric, the raised angle of the raised yarn is 56 degrees, and it is difficult to maintain the upright state of the raised yarn, resulting in the direction of the raised yarn. Therefore, it was inferior in terms of high-grade appearance (×) and inferior in touch smoothness (×).

  The dense ultrashort upholstery fabric of the present invention has a high appearance and a smooth touch similar to a flocked upholstery fabric with a high density of napped yarns and a short napped length, and is also characterized in that the napped yarns are not easily removed from the ground tissue part. Since it has, it can be used for uses, such as interior members, such as a car seat member and a chair upholstery, and a carpet member. In particular, it can be suitably used for the application of a car seat member that requires getting on and off durability.

In the dense ultrashort raised fabric of the present invention, it is an explanatory view for explaining the raised angle α and the raised length of the raised yarn.
