[0006] According to the invention, a knitted fabric and a textile product containing a core-sheath type commingled yarn and having a soft suede-like touch and excellent snagging resistance are obtained.Brief Description of Drawings

[0008] Hereinafter, embodiments of the invention will be described in detail. First, the knitted fabric of the invention contains a core-sheath type commingled yarn, and the core of the commingled yarn is composed of a non-crimped multifilament (a yarn having applied thereto no crimp, which hereinafter may also be referred to as "non-crimped yarn"). When a crimped yarn such as a false twisted crimped textured yarn is located in the core, it may happen that the yarn length difference between the core and the sheath cannot be made large.

[0009] Incidentally, "non-crimped" means that crimping, as in false twisted crimped textured yarns, has not been applied, and means that the crimp degree measured by the following method is 5% or less (most preferably 0%).(Method for Measuring Crimp Degree)

[0010] A test yarn is wound around a sizing reel having a perimeter of 1.125 m to prepare a skein having a dry fineness of 3,333 dtex. The skein is hung on a hanger nail on a scale plate, then an initial load of 6 g is added to its lower part, further a load of 600 g is added, and the skein length L0 at this time is measured. Subsequently, the load is immediately removed from the skein, and the skein is taken off the hanger nail on the scale plate. This skein is immersed in boiling water for 30 minutes, allowing crimps to be developed. The skein after the boiling water treatment is taken out of boiling water, and moisture contained in the skein is removed by absorption on filter paper, followed by air-drying at room temperature for 24 hours. The air-dried skein is hung on the hanger nail on the scale plate, then a load of 600 g is applied to its lower part, and, after 1 minute, the skein length L1a is measured. Subsequently, the load is removed from the skein, and, after 1 minute, the skein length L2a is measured. The crimp degree (CP) of the test filament yarn is calculated using the following formula. CP % = L 1 a − L 2 a / L 0 × 100

[0011] In the commingled yarn, the sheath is preferably a non-crimped multifilament, but may also be a false twisted crimped textured yarn.

[0012] In the commingled yarn, the total fineness is preferably within a range of 50 to 120 dtex (more preferably 50 to 100 dtex). When the total fineness of the commingled yarn is less than the above range, the density of the knitted fabric decreases, which may make snagging more likely to occur. Conversely, when the fineness is more than the above range, it may happen that the resulting knitted fabric has a hard texture, and also the weight per unit becomes too large.

[0013] In addition, in the multifilament located in the core and / or the sheath of the commingled yarn, the number of filaments is preferably within a range of 20 to 200.

[0014] The action of the sheath in the commingled yarn is as follows. When the core yarn shrinks significantly trough a heat treatment, the sheath yarn swells into a mini-pile shape, thereby providing the knitted fabric with a non-raised, soft suede-like touch. In order to achieve a soft suede-like touch, the single fiber fineness of the multifilament located in the sheath is preferably 0.8 dtex or less (more preferably 0.0001 to 0.5 dtex). The cross-sectional shape of the fiber constituting the sheath is not particularly limited, but a round cross-section is preferable in terms of allowing the knitted fabric to develop a non-raised, soft suede touch. In the case of an irregular cross-section, any of triangular, flat, constricted flat, Y-shaped, W-shaped, cross-shaped, and like cross-sections is possible.

[0015] Meanwhile, the action of the core is to shrink significantly trough a heat treatment, allowing the sheath yarn to have a high-density mini-pile structure and develop a soft suede-like touch, and further to increase the density of the knitted fabric and suppress the elongation rate of the knitted fabric, thereby maintaining the snagging resistance. From the viewpoint of shrinkage force, the single fiber fineness of the non-crimped yarn located in the core is preferably 0.5 dtex or more, and more preferably within a range of 0.9 to 2.2 dtex. In the case where the single fiber fineness is less than the above range, it may happen that although the texture is soft, the shrinkage force is insufficient. Meanwhile, in the case where it is more than the above range, it may happen that the texture is hard, making it difficult to obtain an intended knitted fabric. The cross-sectional shape of the fiber constituting the core is not particularly limited, and the fiber may have a circular cross-section or an irregular cross-section as described above.

[0016] As the kind of polymer forming the multifilament located in the core and / or the sheath, polyesters and aliphatic polyamides (nylon 6, nylon 66, etc.) are preferable. Among them, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyesters copolymerized with a third component, and the like are more preferable, for example. Such a polyester may also be a polyester obtained by material recycling or chemical recycling. Further, it may also be a polyester obtained using a catalyst containing a specific phosphorus compound or titanium compound as described in JP2004-270097A or JP2004-211268A. As long as the object of the invention is not impaired, as necessary, the polymer may also contain two or more kinds of micropore-forming agents, cationic dye dyeable agents, coloring inhibitors, heat stabilizers, fluorescent brighteners, delusterants, colorants, moisture absorbents, and inorganic fine particles. In particular, it is preferable that a delusterant is contained in an amount of 0.1 wt% or more (more preferably 0.3 to 2.0 wt%) based on the polymer weight because, as a result, the anti-transparency improves. Specifically, semi-dull polyesters, full-dull polyesters, and cationic dyeable polyesters are preferable. It is preferable that a cationic dye dyeable agent (ester-forming sulfonic acid metal salt compound, etc.) is contained in the polyester because, as a result, antibacterial and deodorizing properties can be added by an acid treatment as described in WO2011 / 048888. In addition, it is preferable that the dyeability is made different between the core and the sheath because, as a result, a spun appearance can be obtained due to the difference in dye absorption.

[0017] As a method for producing the knitted fabric of the invention, first, a non-crimped yarn for the core and a multifilament for the sheath are prepared. At this time, in order to obtain a commingled yarn having a core-sheath structure, it is necessary that the boiling water shrinkage of the core is higher than the boiling water shrinkage of the sheath. For example, as a non-crimped yarn for the core, a yarn obtained by cold-drawing a polyester undrawn yarn (UDY) or a polyester semi-drawn yarn (POY) is preferable for its high boiling water shrinkage.

[0018] Next, the non-crimped yarn for the core and the multifilament for the sheath are aligned and subjected to an air-commingling method such as interlacing processing or a plying method, thereby giving a commingled yarn. In particular, it is preferable that they are subjected to interlacing processing at 30 nodes / m or more (more preferably 60 to 200 nodes / m).

[0019] From the viewpoint of the snagging resistance of the knitted fabric, the boiling water shrinkage (BWS) of the commingled yarn is preferably 40% or more (more preferably 40 to 60%). When the boiling water shrinkage (BWS) is less than 40%, the commingled yarn does not shrink sufficiently during the dyeing process, resulting in a low density of the knitted fabric. Accordingly, in the case where the knitted fabric is snagged on a sharp object, the yarn may be pulled out, resulting in reduced snagging resistance. Meanwhile, when the boiling water shrinkage (BWS) is more than 60%, the shrinkage of the commingled yarn during the dyeing process increases, leading to an increased density of the knitted fabric. As a result, it may happen that although the snagging resistance improves, the texture is too hard.

[0020] The knitted fabric of the invention may also contain a stretch fiber in addition to the commingled yarn described above. At this time, as stretch fibers, from the viewpoint of good stretchability and recoverability, false twisted crimped textured yarns, latent crimped yarns, elastic yarns, and the like are preferable. Here, elastic yarns may be either urethane-based or ester-based. Incidentally, the knitted fabric may be composed only of the commingled yarn and a stretch fiber, but may further contain other yarns such as a non-crimped yarn and a spun yarn.

[0021] Next, the commingled yarn is knitted into a knitted fabric, and then suitably subjected to dyeing processing or water-absorbing processing to obtain a knitted fabric. Due to the thermal history of dyeing processing, etc., the non-crimped yarn for the core contained in the commingled yarn shrinks significantly, making the commingled yarn a core-sheath type. At this time, it is important that the yarn length difference between the core and the sheath contained in the commingled yarn is 25% or more (more preferably 25 to 80%). In the case where the yarn length difference is less than 25%, it may happen that the commingled yarn has no swell, and, for example, the resulting knitted fabric has large gaps between the knitted loops, making the fabric more susceptible to snagging, leading to reduced snagging resistance. In addition, in order to make the yarn length difference between the core and the sheath in the commingled yarn 25% or more, for example, a yarn obtained by cold-drawing a polyester undrawn yarn (UDY) or a polyester partially oriented yarn (POY) may be used as a non-crimped yarn for the core, while a non-crimped multifilament obtained by spinning and drawing (hot-drawing) a polyester in a usual manner, or a false twisted crimped textured yarn obtained by subjecting a polyester partially oriented yarn (POY) to DTY processing, may be used as a multifilament for the sheath.

[0022] Incidentally, as a method for measuring the yarn length difference between the core and the sheath, the following method can be exemplified. First, using a commingled yarn, a tubular-knitted fabric is knitted using a commingled yarn and subjected to dyeing processing, then the tubular-knitted fabric is immersed in an aqueous sodium hydroxide solution, heated, and then dried to reduce the weight of the core yarn. Subsequently, the length (L1) of a predetermined number of wales of the commingled yarn extracted from the tubular-knitted fabric before weight reduction and the length (L2) of the same number of wales of the commingled yarn extracted from the tubular-knitted fabric after weight reduction are each measured under a predetermined load, and the yarn length difference is calculated using the following formula. Yarn length difference % = L 2 − L 1 / L 1 × 100

[0023] Next, a knitted fabric is obtained using the commingled yarn and other yarns as necessary (stretch fiber, non-crimped yarn, etc.). At this time, the structure of the knitted fabric is not particularly limited, and examples thereof include, but are not limited to, in the case of circular knitting, knitted fabrics having knitting structures such as jersey, knit-miss, smooth, rib, moss, plated stitch, double-sided double stitch, and single-sided double stitch, and, in the case of warp knitting, knitted fabrics having knitting structures such as denbigh, half, satin, and queens cord. Also with respect to the number of layers, the structure may be monolayered or may also be multilayered having two or more layers.

[0024] In particular, it is preferable that a fabric is knitted by plating the core-sheath type commingled yarn and the stretch fiber (plated stitch). For example, in the case where a jersey (bare jersey) is knitted by plating the commingled yarn and the stretch fiber (elastic yarn, etc.) (plated stitch), the loops formed by the stretch fiber (elastic yarn, etc.) are smaller than the loops formed by the commingled yarns, and the stretchability of the knitted fabric is mostly attributed to the stretch fiber (elastic yarn, etc.). Accordingly, the mini-pile structure of the commingled yarn is maintained without collapsing, providing not only a soft suede-like touch but also good stretchability and recoverability.

[0025] The weight per unit of the knitted fabric is not particularly limited, but is, from the viewpoint of softness and considering its application, preferably 80 to 300 g / m 2< . A knitted fabric having a weight per unit of less than 80 g / m 2< is not preferable also from the viewpoint of burst strength for application to shirts, etc. In addition, a knitted fabric having a weight per unit of more than 300 g / m 2< may be too heavy to wear (for clothing).

[0026] In addition, from the viewpoint of soft suede touch and snagging resistance, the density of the knitted fabric is preferably within a range of 80 to 150 courses / 2.54 cm and 60 to 120 wales / 2.54 cm. When the density of the knitted fabric is less than the above range, it may happen that although the texture is soft, the snagging resistance decreases. In addition, when the density of the knitted fabric is equal to or more than the above range, it may happen that although the snagging resistance improves, the texture is hard.

[0027] Here, it is preferable that the snagging resistance is Level 3 or higher (more preferably Level 4 or higher) in both the warp and weft directions when tested for 5 hours using a hacksaw in accordance with JIS L 1058-2021, D3 Method.

[0028] In addition, in the case where no stretch fiber is contained, the elongation of the knitted fabric is preferably 25% or less (more preferably 1 to 25%) in the warp direction and 45% or less (more preferably 1 to 45%) in the weft direction. Meanwhile, in the case where the knitted fabric contains a stretch fiber, the elongation of the knitted fabric is preferably 30% or more (more preferably 30 to 150%) in the warp direction and 50% or more (more preferably 30 to 150%) in the weft direction. In addition, it is preferable that the recovery rate of the knitted fabric is 90% or more in both the warp and weft directions.

[0029] The knitted fabric of the invention has the above configuration, and thus has a soft suede touch and also excellent snagging resistance. Further, it also has a woven fabric-like appearance.

[0030] Next, the textile product of the invention is a textile product including the knitted fabric described above and selected from the group consisting of sportswear, outerwear, innerwear, men's clothing, women's clothing, nursing clothing, workwear, car seat upholstery, and bedding.

[0031] This textile product uses the knitted fabric described above, and thus has a soft suede-like touch and also excellent snagging resistance. Further, it also has a woven fabric-like appearance.Examples

[0032] Next, the invention will be described in detail with reference to examples, but the invention is not limited thereto. Incidentally, the physical properties in the examples were measured by the following methods.(1) Weight per Unit

[0035] A tubular-knitted fabric is knitted using a commingled yarn and then subjected to dyeing processing. Next, 3.75 g of the tubular-knitted fabric is immersed in an aqueous sodium hydroxide solution 50 g / L × 250 ml, heated at 2°C / min, kept at 80°C for 270 minutes, and then dried to reduce the weight of the core yarn. Subsequently, the length (L1) of 50 wales of the commingled yarn extracted from the tubular-knitted fabric before weight reduction and the length (L2) of 50 wales of the commingled yarn extracted from the tubular-knitted fabric after weight reduction are each measured under a load of 3.6 g, and the yarn length difference is calculated using the following formula. Yarn length difference % = L 2 − L 1 / L 1 × 100(4) Degree of Interlacing

[0041] Next, using a 36-gauge double circular knitting machine, a circular-knitted fabric having a smooth structure was knitted from the above commingled yarn (blend percentage: 100%).

[0042] Next, the knitted fabric was subjected to dyeing processing using a disperse dye at a temperature of 130°C for a keeping time of 30 minutes. At this time, during the dyeing processing, a treatment with a hydrophilizing agent (polyethylene terephthalate-polyethylene glycol copolymer emulsion) was performed in the same bath in a proportion of 2 ml / l relative to the dyeing liquid, thereby applying the hydrophilizing agent to the knitted fabric. Next, the circular-knitted fabric was subjected to a dry-heat final setting at 160°C for 1 minute.

The evaluation results are shown in Table 1.[Example 2]
