Description

[Technical Field]

[0001] The present invention relates to a warp knitted fabric. [Background technology]

[0002] Conventionally, warp knitted fabrics that can impart anti-slip properties to textile products have been studied. For example, Japanese Patent Laid-Open No. 2011-63919 (Patent Document 1) discloses an invention relating to a power net with anti-slip function, in which anti-slip spandex yarn is inserted on the back side of a power net fabric. Also, Japanese Patent Laid-Open No. 2023-110300 (Patent Document 2) discloses a warp knitted fabric in which an anti-slip knitted structure is knitted into a base structure.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-63919 [Patent Document 2] Japanese Patent Application Publication No. 2023-110300 Summary of the Invention [Problem to be solved by the invention]

[0004] The warp knitted fabrics of Patent Documents 1 and 2 differ in texture and feel from warp knitted fabrics having the same structure as the base structure depending on whether or not they have a structure imparted with an anti-slip feature. Therefore, it has been difficult to impart anti-slip properties to textile products that use some kind of warp knitted fabric while maintaining the performance of the base warp knitted fabric.

[0005] Therefore, it is desirable to impart anti-slip properties to the base fabric while maintaining its characteristics as a fabric. [Means for solving the problem]

[0006] The warp knitted fabric of the present invention comprises a base structure composed of at least a first yarn and a second yarn, and an anti-slip structure including at least an anti-slip yarn and knitted into one side of the base structure, wherein the anti-slip yarn of the anti-slip structure moves at least one wale per course and forms loops only at the direction change portions.

[0007] This configuration allows the anti-slip threads to be exposed on one side of the fabric. This makes it possible to impart anti-slip properties while maintaining the characteristics of the base fabric. If the base fabric has high elasticity, it is possible to impart anti-slip properties without compromising that elasticity. Even if the base fabric has low elasticity, it is possible to impart anti-slip properties while maintaining the elasticity of the base fabric.

[0008] Preferred embodiments of the present invention will be described below, but the scope of the present invention is not limited to the preferred embodiments described below.

[0013] In one aspect of the warp knitted fabric according to the present invention, the first yarn and the second yarn are preferably inelastic yarns.

[0014] This configuration allows for the provision of anti-slip properties to fabrics with relatively low stretchability.

[0015] In one embodiment, the warp knitted fabric according to the present invention preferably has at least one of a static friction coefficient and a dynamic friction coefficient of 1.0 or more in both the longitudinal and transverse directions.

[Figure 2] FIG. 2 is a diagram showing the structure of the warp knitted fabric according to the first embodiment for each reed.

[Figure 4] FIG. 10 is a diagram showing the structure of a warp knitted fabric according to a second embodiment for each reed. DETAILED DESCRIPTION OF THE INVENTION

[0027] Two embodiments of the warp knitted fabric according to the present invention will be described with reference to the drawings. The warp knitted fabric according to either embodiment can be knitted using a normal knitting device and knitting method. That is, the warp knitted fabric according to either embodiment can be knitted using a tricot machine, a Russell machine, or the like.

[0028] First Embodiment The warp-knitted fabric 1 according to the first embodiment comprises a base structure 2 and a non-slip structure 3 (Figures 1 and 2). The base structure 2 is composed of a first base yarn 21 (an example of a first yarn) and a second base yarn 22 (an example of a second yarn). The non-slip structure 3 is composed of non-slip yarn 31 and is knitted into the sinker loop side (an example of a single-sided side) of the base structure 2.

[0029] The warp knitted fabric 1 is knitted with three reeds. Reed GB1 is threaded with an anti-slip yarn 31, reed GB2 is threaded with a first base yarn 21, and reed GB3 is threaded with a second base yarn 22, all of which are threaded as a full set. Reeds GB2 and GB3 are used to knit a base structure 2, and reed GB1 is used to knit an anti-slip structure 3.

[0030] In the base structure 2, the first base yarn 21 is made up of two courses of repeating units of 1.0 / 1.2 / / , and the second base yarn 22 is made up of two courses of repeating units of 1.2 / 1.0 / / . As is clear from the repeating units of the first base yarn 21 and the second base yarn 22, the base structure 2 is a Denbigh structure.

[0031] The first base yarn 21 is a non-elastic yarn made of polyester fiber, 56 decitex, and 24 filaments. The second base yarn 22 is an elastic yarn made of polyurethane fiber, 56 decitex, and monofilament. The base structure 2 is composed of individual non-elastic and elastic yarns and is a relatively highly elastic structure.

[0032] The anti-slip yarn 31 constituting the anti-slip structure 3 is a yarn that exhibits anti-slip properties when it comes into contact with other objects. The anti-slip yarn 31 can be polyurethane yarn, microfibers such as polyester yarn and nylon yarn, split filament yarn, nanofiber, natural rubber yarn, and synthetic rubber yarn. Alternatively, the anti-slip yarn 31 may be a covering yarn obtained by covering a yarn selected from the group consisting of microfibers such as polyester yarn and nylon yarn, split filament yarn, and nanofiber. Since polyurethane yarn is a relatively soft material, it tends to deform when it comes into contact with other objects, increasing the contact area. This gives it a non-slip property. The following explanation will use the case where the anti-slip yarn 31 is polyurethane yarn as an example. Compared to other types of yarn, split filament yarns and nanofibers have thinner and more numerous filaments, so many filaments come into contact with other objects, increasing the contact area. This gives them a non-slip property. Note that the relationship between the type of anti-slip yarn 31 and the mechanism by which it exhibits anti-slip properties is not limited to the above example. That is, the anti-slip thread 31 may be a thread that exhibits anti-slip performance through a mechanism different from that exemplified above.

[0033] The anti-slip yarn 31 is preferably a polyurethane yarn. The advantage of using a polyurethane yarn for the anti-slip yarn 31 is that it can exhibit excellent anti-slip performance and can impart anti-slip performance regardless of the characteristics of the base structure (highly elastic base structure, low elastic base structure, etc.).

[0034] In the non-slip structure 3, the non-slip yarn 31 consists of eight courses of repeating units of 0.1 / 2.2 / 3.3 / 4.4 / 5.4 / 3.3 / 2.2 / 1.1 / / . The non-slip yarn 31 is an elastic yarn made of polyurethane fiber, 56 decitex, monofilament. As shown in the repeating units above, the non-slip yarn 31 moves one wale per course. Furthermore, the non-slip yarn 31 forms loops only in the direction change sections (the first and fifth courses).

[0035] By not forming loops (not needle wrapping) in areas other than where the anti-slip yarn 31 changes direction (the 2nd to 4th courses and the 6th to 8th courses), the anti-slip structure 3 is exposed on the surface of the warp knitted fabric 1 without being knitted into the base structure 2. In addition, since the anti-slip yarn 31 is oblique in opposite directions in the first half (the 1st to 4th courses) and the second half (the 5th to 8th courses) of the repeating unit, the warp knitted fabric 1 can exhibit almost uniform anti-slip performance in any direction.

[0036] Furthermore, because the anti-slip yarns 31 do not form loops except at the direction change portions, the properties of the anti-slip yarns 31 are less likely to be reflected in the overall fabric properties of the warp knitted fabric 1 in terms of characteristics such as stretchability and breathability. Therefore, the stretchability and other characteristics of the warp knitted fabric 1 are generally similar to those of the base weave 2 (here, a Denbigh weave). In other words, the warp knitted fabric 1 can be said to be a fabric that retains the fabric characteristics of the base weave 2 while adding anti-slip performance due to the anti-slip weave 3. Therefore, by replacing the fabric of a product that uses a fabric with the same weave as the base weave 2 with the warp knitted fabric 1, it is possible to realize a product that has been given anti-slip performance while maintaining the characteristics of the previous product.

[0037] The spacing between loops of the anti-slip yarn 31 (number of wales) is determined taking into consideration the required level of anti-slip performance, the type and fineness of the anti-slip yarn 31, etc. For the same anti-slip yarn 31, the greater the spacing between loops of the anti-slip yarn 31, the higher the anti-slip performance tends to be. Also, for the same spacing between loops, the greater the fineness of the anti-slip yarn 31, the higher the anti-slip performance tends to be.

[0038] It is preferable that the proportion of anti-slip yarn 31 in the entire structure of the warp-knitted fabric 1 is 7% by mass or more. When the proportion of anti-slip yarn 31 is within the above range, anti-slip performance is easily exhibited. The proportion of anti-slip yarn 31 in the entire structure of the warp-knitted fabric 1 is appropriately selected within a range that does not impair the characteristics of the base structure 2 as a fabric. Therefore, the upper limit of the proportion of anti-slip yarn 31 may vary depending on the base structure 2.

[0039] Examples of products utilizing warp-knitted fabric 1 include joint supports. The base fabric 2 is a highly elastic fabric composed of individual elastic and non-elastic threads, making it suitable for supports that require high mobility. By using warp-knitted fabric 1 as the lining for this type of support, the high elasticity provided by the base fabric 2 is retained while the anti-slip performance of the anti-slip fabric 3 is added. Therefore, a support that is less likely to come off can be created.

[0040] Second Embodiment The warp-knitted fabric 4 according to the second embodiment comprises a base structure 5 and a non-slip structure 6 (Figures 3 and 4). The base structure 5 is composed of a first base yarn 51 (an example of a first yarn) and a second base yarn 52 (an example of a second yarn). The non-slip structure 6 is composed of non-slip yarn 61 and is knitted into the back side (an example of a single side) of the base structure 5. The structure and characteristics of the non-slip structure 6 are the same as those of the warp-knitted fabric 1 according to the first embodiment.

[0041] The warp-knitted fabric 4 is knitted using a three-reed system. The anti-slip yarn 61 is threaded through reed GB1, the first base yarn 51 through reed GB2, and the second base yarn 52 through reed GB3, all in their full sets. The base structure 5 is knitted by reeds GB2 and GB3, and the anti-slip structure 6 is knitted by reed GB1.

[0042] In the base structure 5, the first base yarn 51 consists of two courses of repeating units of 0.1 / 1.0 / / , and the second base yarn 52 consists of two courses of repeating units of 1.0 / 3.4 / / . As is clear from the repeating units of the first base yarn 51 and the second base yarn 52, the base structure 5 is queen's coat.

[0043] The first base yarn 51 and the second base yarn 52 are both inelastic polyester fibers, 56 decitex, 24 filaments. Since both the first base yarn 51 and the second base yarn 52 are inelastic yarns, the base structure 5 has relatively low stretchability.

[0044] As in the first embodiment, the anti-slip structure 6 does not affect the overall stretchability and other properties of the warp knitted fabric 4, so the warp knitted fabric 4 reflects the properties of the base structure 5, which has relatively low stretchability. Therefore, unlike the warp knitted fabric of the first embodiment, the warp knitted fabric 4 has relatively low stretchability. Examples of products that use the warp knitted fabric 4 include bed pads and entrance mats. Using the warp knitted fabric 4 as a lining material for these products can impart anti-slip properties to the back of the product, making it possible to create products that are less likely to slip off the installation site. For example, a bed mat using the warp knitted fabric 4 as the lining is less likely to slip off the bed.

[0045] [Method for measuring static and dynamic friction coefficients] The static and dynamic friction coefficients were measured according to JIS K 7125:1999. The test room environment during the measurements was set at a temperature of 20°C and a humidity of 65% RH. A friction table with a mass of 200 g and a contact area of ​​approximately 40 cm was placed on the friction table. 2The test piece was wrapped around a 6.3 cm x 6.3 cm slider, which was then pulled horizontally until the speed reached 10 cm per minute. The frictional resistance (unit: N) during this series of movements was measured using an Instron tensile tester (model: 5564). A test piece measuring 6.3 cm x 13.0 cm was used to measure the coefficient of friction in the longitudinal direction of the warp knitted fabric. A test piece measuring 13.0 cm x 6.3 cm was used to measure the coefficient of friction in the transverse direction of the warp knitted fabric. The static friction coefficient was calculated by dividing the frictional resistance when the stationary slider began to move by the test load (200 g load = 1.96 N). The kinetic friction coefficient was calculated by dividing the frictional resistance when the slider was moving at a speed of 10 cm per minute by the test load (200 g load = 1.96 N).

[0046] [Anti-slip performance of warp knitted fabrics] It is preferable that at least one of the static and dynamic friction coefficients of the warp knitted fabrics 1 and 4 is 1.0 or more in both the longitudinal and transverse directions, and it is more preferable that both the static and dynamic friction coefficients are 1.0 or more in both the longitudinal and transverse directions. If this requirement is met, the warp knitted fabrics 1 and 4 are likely to meet the required anti-slip performance when used in anti-slip applications. There are no particular limitations on the upper limits of the static and dynamic friction coefficients, but they can be, for example, 2.5 or less.

[0047] [Method for manufacturing warp knitted fabric] The warp knitted fabrics 1 and 4 according to the above-described embodiments can be manufactured using known knitting devices and knitting methods. Examples of knitting devices that can be used include tricot machines and raschel machines. Non-limiting examples of tricot machines include the HSK2 series, HSK3 series, and HSK4 series (all manufactured by Karl Mayer). Non-limiting examples of raschel machines include the RSE4 series, RSE5 series, and RSE6 series (all manufactured by Karl Mayer). The number of guide bars in the knitting device can be, for example, between two and six, but is not limited to this range. All or only some of the guide bars in the knitting device may be used. In either case, the frontmost guide bar is used to knit the non-slip structures 3 and 6, and the other guide bars are used to knit the base structures 2 and 5.

[0048] The warp knitted fabrics 1 and 4 may be manufactured through treatments that are typically performed on warp knitted fabrics. Examples of such treatments include, but are not limited to, scouring, dyeing, and setting. The conditions for each treatment are also arbitrary.

[0049] Other Embodiments Finally, other embodiments of the warp knitted fabric according to the present invention will be described. Note that the configurations disclosed in the following embodiments can be applied in combination with the configurations disclosed in other embodiments, as long as no contradiction occurs.

[0050] In the above embodiment, the non-slip yarn 31 of the non-slip structure 3 is a 56-dtex polyurethane yarn. However, the present invention does not limit the fineness of the non-slip yarn. However, a non-slip yarn fineness of 22 dtex or more is preferable because it allows for a relatively high production speed of the warp knitted fabric. A non-slip yarn fineness of 44 dtex or more is more preferable. Furthermore, a non-slip yarn fineness of 470 dtex or less is preferable because it makes handling of the non-slip yarn relatively easy when producing the warp knitted fabric and makes it easier to obtain a warp knitted fabric with a good texture. A non-slip yarn fineness of 310 dtex or less is more preferable, and a non-slip yarn fineness of 156 dtex or less is even more preferable. The fineness of the non-slip yarn can be selected taking into consideration the use of the warp knitted fabric. For example, if a thin fabric with low kickback power is desired, it is preferable to use an anti-slip yarn with a relatively small fineness (44 decitex, 56 decitex, etc.), and if a thick fabric with high kickback power is desired, it is preferable to use an anti-slip yarn with a relatively large fineness (156 decitex, 310 decitex, etc.).

[0051] In the above embodiment, the anti-slip thread 31 of the anti-slip structure 3 is a monofilament polyurethane thread. However, the present invention is not limited to a filament configuration of the anti-slip thread.

[0052] In the above embodiment, the number of wales in the repeating unit of the non-slip structure is greater than the number of wales in the repeating unit of the base structure. However, in the present invention, the relationship between the number of wales in the repeating unit of the non-slip structure and the number of wales in the repeating unit of the base structure is not limited.

[0053] In the above embodiment, an example was shown in which all three reeds were threaded with a full set of yarn. A full set refers to, for example, a 28-gauge knitting machine having 28 guides and needles in the horizontal direction (well direction) between inches, with yarn threaded through all 28 guides and knitting the fabric with the needles. However, the threading arrangement when manufacturing the warp knitted fabric of the present invention is not limited to a full set. For example, a 1-in-1-out arrangement is when a yarn is threaded through every other guide and knitted with the needles. In this threading arrangement, knitting can be performed such that a yarn is threaded through the 1-in section and a withdrawal yarn is used in the 1-out section. Other non-limiting examples of threading arrangements include 1-in-2-out, 2-in-1-out, 3-in-1-out, and 1-in-3-out. For example, a 28-gauge knitting machine can have a maximum of 28 threads and a minimum of one thread.

[0054] For example, in the case of a fabric with a mesh-like base weave, the mesh-like fabric is knitted by removing the threads on each of the two reeds that knit the base weave. A full set of non-slip weaves, or a non-slip weave that has been removed, may be knitted on top of this base weave. In other words, only the base weave may be removed and a full set of non-slip weaves may be knitted, or all three reeds may be knitted using threads other than the full set.

[0055] However, the fewer the number of non-slip yarns used in the non-slip structure, the higher the non-slip effect. Therefore, from the viewpoint of maximizing the non-slip effect, it is preferable to knit with a full set of non-slip yarns.

[0056] The above examples have been described using the case where the base weave is a Denbigh weave (first embodiment) and a Queen's coat weave (second embodiment). However, the weave structure of the base weave is not limited in the present invention, and it can be any warp knitted fabric weave knitted using a tricot machine, a Russell machine, or the like. Examples of base weaves knitted using a tricot machine include, but are not limited to, half, back half, satin, atlas, Queen's coat, mesh, tulle, double stitch, double Denbigh, double barcode, and insert. Examples of base weaves knitted using a Russell machine include, but are not limited to, half, back half, satin, atlas, Queen's coat, mesh, tulle, double stitch, double Denbigh, double barcode, insert, and power net. Examples of base weaves knitted using a Russell machine include, but are not limited to, triskin.

[0057] The above describes, as examples, a case in which the yarns constituting the base weave are polyester fiber and polyurethane fiber (first embodiment) and a case in which both are polyester fiber (second embodiment). However, in the present invention, the yarns constituting the base weave and their combinations are not limited. Therefore, the yarns constituting the base weave may be synthetic fibers such as polyester fiber, nylon fiber, and polyurethane elastic fiber; semi-synthetic fibers such as acetate fiber and triacetate fiber; regenerated fibers such as rayon fiber and cupra fiber; and natural fibers such as cotton, linen, silk, and wool, but are not limited to these. Furthermore, the yarns constituting the base weave may be textured yarns such as textured polyester yarns and textured nylon yarns, or covering yarns with a core thread of polyurethane elastic fiber.

[0058] In the above, a joint supporter is exemplified as an application of the warp knitted fabric 1 according to the first embodiment, and a bed mat and an entrance mat are exemplified as applications of the warp knitted fabric 4 according to the second embodiment. However, the above are merely examples, and the applications of the warp knitted fabric according to the present invention are not limited to a wide range of applications such as sports, medical, and bedding.

[0059] Regarding other configurations, it should be understood that the embodiments disclosed in this specification are illustrative in all respects and that the scope of the present invention is not limited thereby. Those skilled in the art will easily understand that appropriate modifications are possible without departing from the spirit of the present invention. Therefore, other embodiments modified without departing from the spirit of the present invention are naturally included in the scope of the present invention. [Example]
