Definitions

  • the present invention relates to a weft knitted fabric.
  • Patent Document 1 discloses a single knit fabric having a twill-like appearance on the front side and a pile-like appearance on the back side, which is constructed by alternately arranging thick yarn A and thinner yarn B having an apparent thickness ratio of 1/1.5 or less.
  • Knitted fabrics used in comfortable clothing are required to have a smooth texture.
  • the stitches By thinning the yarn constituting the knitted fabric, the stitches become smaller, resulting in a knitted fabric with a smooth sinker loop surface, but at the same time, the undulations of the needle loop surface are also reduced. Therefore, with conventional knitted fabrics, it has been difficult to achieve both the smoothness of the sinker loop surface and the designability of the large undulations of the needle loop surface.
  • the needle loop surface shows an undulating kanoko-like appearance, but the sinker loop surface does not have a smooth texture because the stitches forming the pile protrude.
  • an elastic fiber such as polyurethane is knitted in order to impart stretchability, the stitches become smaller, which causes a problem that the undulations on the needle loop surface become even smaller.
  • the problem that the present invention aims to solve is to provide a weft knitted fabric that is stretchable, has excellent smoothness on the sinker loop surface, and has large undulations on the needle loop surface.
  • a weft knitted fabric comprising: all courses containing inelastic yarn; any course containing elastic yarn; one course, or two or more consecutive courses of the same structure, course A, course B, and course C, repeated in this order toward the knitting end direction; course A, course B, and course C each having a structure different from one another; course A containing knit; course B containing knit and tuck; course C containing knit and welt, and further containing elastic yarn; comprising one or more tuck stitches in which the knit of course A and the tuck of course B are continuously formed on the same wale; the tuck stitch and the welt of course C are continuously formed on the same wale in at least one or more places; and a ratio (L C /L A ) of the loop length (L A ) of course C to the loop length (L A ) of course A is 0.50 to 0.95.
  • the weft knitted fabric according to any one of [1] to [16] which is a single weft knitted fabric.
  • a shirt comprising the weft knitted fabric according to any one of [1] to [17].
  • the weft knitted fabric of the present invention has stretchability, excellent smoothness on the sinker loop surface, and large undulations on the needle loop surface, making it suitable for use in textile products that come into direct contact with the skin and require design, such as shirts, innerwear, bottom wear, jackets, masks, etc., and is particularly suitable for use in shirts.
  • FIG. FIG. FIG. 1 is an example of a weft knitted fabric of the present invention.
  • FIG. 1 is an explanatory diagram of a knitting structure of an example of a weft knitted fabric of the present invention and a relationship between the knitting structure and the notations in the following Tables 1 to 5 corresponding to the knitting structure.
  • One embodiment of the present invention is a weft knitted fabric, the fabric comprising: all courses containing inelastic yarn; any course containing elastic yarn; one course, or two or more consecutive courses of the same weave, course A, course B, and course C, repeated in this order in the knitting end direction; the course A, course B, and course C each having a different weave; the course A includes a knit; the course B includes a knit and a tuck; the course C includes a knit and a welt, and further includes elastic yarn; the knit of the course A and the tuck of the course B include one or more tuck stitches formed continuously on the same wale; the tuck stitch and the welt of the course C are continuous on the same wale in at least one or more places; and the ratio (L C /L A ) of the loop length of the course C (L A ) to the loop length of the course A is 0.50 to 0.95.
  • needle loop surface refers to the surface composed of needle loops, which are the crests of the loops, and is synonymous with the technical face (TF) (the front side of the paper in Figures 1 to 3).
  • the "sinker loop surface” refers to the surface that is made up of the sinker loop, which is the valley of the loop, and is synonymous with the technical back (TB) (reverse side of the pages in Figures 1 to 3)
  • non-elastic yarn refers to fibers whose breaking elongation is less than 100%.
  • elastic yarn refers to a fiber with a breaking elongation of 100% or more.
  • Course A includes knit.
  • Course A may include a knit structure other than knit, but is preferably composed of knit only (see FIG. 4).
  • the course A may be composed of only one course, or may be composed of two or more consecutive courses of the same weave. When the course A is composed of two or more consecutive courses of the same weave, the yarns contained in each course may be different.
  • Course B includes knit and tuck.
  • Course B may include a knit structure other than knit and tuck, but is preferably composed of only knit and tuck (see FIG. 4).
  • Course B may be composed of only one course, or may be composed of two or more consecutive courses of the same weave (see FIG. 4).
  • course B is preferably composed of two or more consecutive courses, and more preferably composed of two or three or more consecutive courses.
  • course B is composed of two or more consecutive courses of the same weave, the yarns contained in each course may be different.
  • Course C includes knit and welt.
  • Course C may include a knit structure other than knit and welt, but is preferably composed of only knit and welt (see FIG. 4).
  • course C composed of only knit and welt, the yarn length of course C becomes smaller, the needle loops of course C become smaller, and the difference in stitch size between course A and the tuck knit formed by course B becomes larger, so that the undulations formed on the needle loop surface become larger.
  • the course C includes an elastic yarn. By including the elastic yarn in the course C, the stitches of the course C become smaller due to contraction of the elastic yarn (see FIG. 4), causing a difference in size between the stitches forming the protrusions and the stitches, and increasing the undulations of the needle loop surface.
  • the welt has few contact points with other yarns on the sinker loop surface, and the degree of freedom of the yarn is high (see FIG. 4), so including the elastic yarn in the course C allows the elasticity of the elastic yarn to be fully exerted, improving the stretch recovery.
  • Course C may consist of only one course, or two or more consecutive courses of the same weave. From the viewpoint of suppressing the protrusion of the welts into the sinker loop due to overlapping of the welts and improving the smoothness of the sinker loop surface, it is preferable that course C consists of one to three courses. When course C consists of two or more consecutive courses of the same weave, the yarns contained in each course may be different.
  • course A, course B, and course C are repeated in this order toward the end of knitting.
  • the weft knitted fabric of this embodiment may be knitted in the order of A, B, C, A... from the beginning to the end of knitting, or one or more of course A, course B, and course C may be knitted from a plurality of courses, such as A, B, B, C, A... or A, B, B, C, C, A... (see Tables 1 to 5 and FIG. 6).
  • a tuck knit is formed by continuing a knit of course A and a tuck of course B on the same wale (see the wale on the left side of Fig. 4).
  • a large undulation is formed on the needle loop surface by forming a tuck knit.
  • the tuck stitch formed by the knit of course A and the tuck of course B and the welt of course C are continuous on the same wale at least in one place (see the wale on the left side of Figure 4).
  • the tuck stitch and the welt of course C be continuous on the same wale at least in one place, so the tuck stitch formed by course A and course B becomes large, so the undulations of the needle loop surface become large, and the welt structure of course C arranged on the sinker loop surface fills the depressions on the sinker loop surface formed by course A and course B, so the smoothness of the sinker loop surface increases.
  • the ratio of the number of tuck stitches that are continuous on the same wale as the welt of course C to the total number of tuck stitches is preferably 50% or more, and more preferably 100%.
  • one complete structure refers to the smallest repeating unit of the knitting structure that constitutes the knitted fabric.
  • the tuck stitches that make up the "total number of tuck stitches in one complete structure" can be included not only in course B, but also in course A and/or course C.
  • the ratio (L C /L A ) of the loop length L C of course C to the loop length L A of course A is 0.50 to 0.95, preferably 0.60 to 0.90, and more preferably 0.68 to 0.85.
  • the needle loops of course C do not become too small, so that it is possible to obtain stretchability suitable for wearing.
  • the method for adjusting the L C /L A to 0.50 to 0.95 is not particularly limited, but examples thereof include a method of increasing the number of knits in course A and a method of decreasing the number of knits in course C.
  • the weft knitted fabric of this embodiment contains inelastic yarn in all courses.
  • inelastic yarn natural fibers, synthetic fibers, regenerated (refined) cellulose fibers, etc. can be used. Examples of natural fibers include cotton, hemp, silk, wool, etc.
  • polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, and polyolefin fibers such as polyethylene and polypropylene, and these can be selected arbitrarily as bright yarns, semi-dull yarns, full-dull yarns, etc.
  • the cross-sectional shape of the fiber can be any cross-sectional shape such as round, elliptical, W-shaped, cocoon-shaped, hollow yarn, etc., and the form of the fiber is not particularly limited, and it may be raw yarn, false twist, or other crimped yarn.
  • regenerated (refined) cellulose fibers include rayon, cupra, lyocell, etc. Regenerated (refined) cellulose fibers can be in the form of a single yarn as raw yarn or twisted yarn, or in the form of a composite yarn with the synthetic fibers exemplified below.
  • the weft knitted fabric of this embodiment includes an elastic yarn in course C, and also includes an elastic yarn in either course A or course B, preferably course B.
  • the weft knitted fabric of this embodiment includes an elastic yarn in addition to having the configurations of course A, course B, and course C described above, and thus it is possible to impart stretchability to the weft knitted fabric while suppressing flattening of the needle loop surface due to contraction of the elastic yarn.
  • course A does not contain elastic yarn, i.e., is made only of inelastic yarn.
  • a made only of inelastic yarn tuck stitches can be formed without shrinking the needle loops, making it easier to form larger undulations on the needle loop surface, and furthermore, the stitches of the tuck stitches are less likely to close, allowing air to pass through more easily, improving the quick-drying properties of the weft knit fabric.
  • the knitted fabric of this embodiment preferably includes an elastic yarn in the course on the end side of knitting.
  • the knitted fabric of this embodiment can minimize the shrinkage of the needle loop, making it easier to prevent the flattening of the needle loop surface due to the elastic yarn.
  • the knitted fabric of this embodiment has fewer inelastic yarns that secure the elastic yarn in the needle loop compared to when elastic yarn is included in the course on the start side of knitting, so the elastic yarn is more easily deformed and it is easier to obtain stretch and recovery suitable for wearing.
  • the material of the elastic yarn and the spinning method are not particularly limited, and polyurethane-based or polyether ester-based elastic yarns can be used, and for example, dry-spun or melt-spun yarns can be used. It is preferable that the elastic yarn does not lose its elasticity at around 180°C, which is the normal processing temperature for the presetting step during dyeing processing.
  • the elastic yarn may contain functionalizing agents such as special polymers or inorganic substances to impart functionality according to the purpose, such as high setting ability, deodorizing properties, and antibacterial properties.
  • the fineness of the elastic yarn is preferably 9 to 155 dtex, and more preferably 15 to 80 dtex from the viewpoint of ease of manufacturing the weft knitted fabric.
  • the weft knitted fabric of this embodiment can include, as the elastic yarn, a bare yarn (bare yarn) that is not covered by a non-elastic yarn, or a covering yarn in which a bare yarn is covered by a non-elastic yarn, but from the viewpoint of increasing the smoothness of the back surface of the fabric, a bare yarn (bare yarn) is preferable. Furthermore, in a weft knitted fabric using bare yarn as the elastic yarn, moisture is less likely to remain around the elastic yarn when dealing with sweat generated in large amounts during exercise or when worn in a hot environment, and the knitted fabric dries faster, making it more comfortable to wear. Furthermore, in a weft knitted fabric using bare yarn as the elastic yarn, the fiber diameter of the bare yarn is smaller than that of a covering yarn, so that unevenness is less likely to form on the needle loop surface, resulting in a smoother texture.
  • a covering yarn As the elastic yarn, a single covered yarn (SCY) or a double covered yarn (DCY) can be used as the covering yarn, and the total fineness of the covering yarn is preferably 30 to 200 dtex, and from the viewpoint of ease of knitted fabric production, 40 to 155 dtex is even more preferable.

  • the yarn formed in course C fills the depression formed on the sinker loop surface by courses A and B, making it easy to smooth the sinker loop surface.
  • the welt of course C can be prevented from protruding onto the sinker loop surface, improving the smoothness of the sinker loop surface and increasing the undulations of the needle loop surface.
  • the inelastic yarn contained in course C is a long fiber.
  • long fibers in course C frictional resistance with the knitting needles during knitting is reduced, and knitting is possible with a smaller yarn length compared to short fibers of the same fineness, resulting in smaller stitches and making it possible to increase the undulations of the needle loop surface.
  • fuzz on the sinker loop surface is reduced, improving smoothness.
  • the single yarn fineness of the inelastic yarn contained in course C is preferably 3.0 dtex or less, more preferably 2.5 dtex or less, and even more preferably 1.8 dtex or less, from the viewpoint of preventing the yarn from buckling at the welt and protruding onto the sinker loop surface and improving smoothness. Furthermore, since the single yarn fineness of the inelastic yarn contained in course C is 3.0 dtex or less, the welt of course C is less likely to protrude onto the sinker loop surface, so that the welt of course C is reliably positioned in the depression on the sinker loop surface formed by the tuck knitting, greatly improving the smoothness of the sinker loop surface.
  • the ratio (F BS /F BE ) of the fineness (F BS ) of the inelastic yarn in the course at the start of knitting to the fineness (F BE ) of the inelastic yarn in the course at the end of knitting is preferably less than 1.0, more preferably 0.20 to 0.95, and even more preferably 0.25 to 0.90.
  • F BS /F BE is less than 1.0, the arrangement of the two inelastic yarns during tuck knitting is stable, making it possible to reduce the basis weight of the fabric and preventing the undulations of the needle loop surface from becoming small.
  • the fineness of the inelastic yarn contained in the course on the knitting end side of course B is preferably 200 dtex or less and/or long fiber.
  • the inelastic yarn contained in the course on the knitting end side of course B is knitted closest to the sinker loop surface side, so by having a fineness of 200 dtex or less and/or long fiber, the sinker loop surface tends to be smooth. If course B consists of only one course, that one course becomes the "course on the knitting end side".
  • the single yarn fineness of the inelastic yarn included in course B on the knitting end side is preferably 3.0 dtex or less, more preferably 2.5 dtex or less, and even more preferably 1.8 dtex or less, from the viewpoint of preventing the yarn from buckling and protruding onto the sinker loop surface and improving smoothness.
  • the ratio (F BS /F A ) of the fineness F BS of the inelastic yarn included in the start course of knitting in course B to the fineness F A of the largest inelastic yarn included in course A is preferably less than 1.00, and more preferably 0.90 or less.
  • F BS /F A is less than 1.00, the undulations of the needle loop surface do not become small, making it possible to reduce the basis weight of the fabric and providing a knitted fabric with excellent quick-drying properties.

  • the weft knitted fabric of this embodiment is preferably a single weft knitted fabric.
  • a single weft knitted fabric refers to a fabric knitted on a single weft knitting machine, and is a single-layered fabric having a needle loop surface and a sinker loop surface.
