Description

  The present invention relates to an elastic warp knitted fabric having a pile surface, a bandage having the elastic warp knitted fabric, and a female surface fastener.

  As is well known, bandages are medical instruments for protecting affected areas and joints. In recent years, bandages have been provided with stretchability to improve the ability to suppress displacement and loosening after wearing. Patent Document 1 discloses an elastic warp knitted fabric as an example. The elastic warp knitted fabric of the same document inserts elastic warp into a zigzag for each of a plurality of chain knittings (carabiner needles) knitted with all the stitches closed, and several wales of these chain knittings Are connected by elastic wefts. In addition, there are some in which local creases are dotted by embossing or the like on the knitted fabric (or woven fabric). In this case, even if the yarn itself is not stretchable, the knitted fabric can be stretched by changing the degree of opening of the folds.

  On the other hand, as an example of a female surface fastener having a warp knitting structure, Patent Document 2 discloses a warp knitted base fabric for a surface fastener. The warp knitted base fabric for hook-and-loop fasteners of the same document is formed by knitting insertion yarns by a marquette structure into a net-like shape with respect to a warp knitted ground structure knitted by ground yarn and pile knitting yarn. This ground structure has a plurality of chain stitches knitted by ground yarn, and the pile knitting yarn is knitted so as to straddle between these wales. As a result, a pile loop of pile knitting yarn is obtained. In order to maintain the shape of the base fabric itself and prevent the pile loop from coming off, the back side of the base fabric is coated with a synthetic resin or the like.

  Patent Document 3 discloses a hook strip in which bowl-shaped resin hooks are arranged as an example of a male surface fastener. The hook is composed of a rod-shaped stem protruding from the support surface and a disk-shaped head formed integrally with the stem at the tip of the stem.

  In order to fix the end of the bandage after winding, a bandage stopper, a surgical tape or a net bandage is used. However, the bandage stopper bites the bandage with a sharp nail, but when the bandage is wound around an affected part such as a joint, the bandage tends to come off from the bandage. Surgical tape can hold the bandage firmly by attaching a tape of sufficient length, but there is a problem that the adhesive part tends to break down the structure of the bandage. The net bandage can eliminate the above-mentioned problems, but the bandage is effectively wound twice, and there is a concern about the decrease in mobility due to the increase in the overall thickness on the patient side. There is a concern that the cost will increase.

  As another fixing device for solving such a problem, a male surface fastener having a large number of small hooks (buttocks) on the surface is conceivable. That is, the bandage functions as a female surface fastener that is locked to the male surface fastener. The male hook-and-loop fastener can secure a plurality of hooks to be locked to the bandage over a wide range as compared with a general bandage stopper. Moreover, it is not necessary to form a sharp nail | claw part along the direction which faces a bandage. Moreover, it is not necessary to wrap the entire bandage like a net bandage. However, since a general female-type surface fastener having stretchability is thick, when the knitted tissue is applied to the bandage, the wearability is deteriorated, and it is difficult to secure a sufficient number of windings of the bandage. In addition, the movement of the joint part tends to be difficult.

It is an organization chart of the warp knitted fabric (elastic pile warp knitted fabric) concerning one embodiment of the present invention. It is an organization chart of the warp knitted fabric concerning one embodiment of the present invention. It is an organization chart of the warp knitted fabric concerning one embodiment of the present invention.

  Hereinafter, warp knitted fabrics according to embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted. As described below, the warp knitted fabric of the present embodiment has a plurality of pile loops on the surface, and has stretchability in the course direction (warp direction) Dc and the wale direction (weft direction) Dw. In addition, this warp knitted fabric can be used as a bandage or a female type surface fastener (or its base fabric) by applying a known technique. However, the present invention is not limited to these application forms.

  FIG. 1 is an organization chart (knitting pattern) of a warp knitted fabric (elastic pile warp knitted fabric) according to the present embodiment. As shown in this figure, the warp knitted fabric of this embodiment includes a plurality of chain knitted fabrics 12 knitted with ground yarns 14, a pile knitted fabric 17 knitted with pile yarns 18, a ground yarn 14 and pile yarns 18. Insertion yarns 16 inserted into the respective stitches 14a and 18a. The chain knitting 12 and the insertion yarn 16 define the basic shape (ground texture) of the warp knitted fabric, and the pile knitted fabric 17 is formed as the surface knitted fabric.

The warp knitted fabric of this embodiment is manufactured by a warp knitting machine such as a Russell knitting machine. As shown in FIG. 1, the pile yarn 18 to the reed (before reed) L ₁ of the warp knitting machine is Tsuito, reed (middle reed) L ₂ to ground yarn 14 is Tsuito, reed (rear reed) L ₃ The insertion thread 16 is passed through. Therefore, as described above, the pile yarn 18 forming the pile loop 18b is exposed most on the surface of the warp knitted fabric. As described below, may be Tsuito auxiliary yarns 22 to the guide bar L _4.

  The chain stitch 12 has a structure of 02/20 // which is a basic structure of the chain stitch, for example. The chain knitting 12 is knitted in a state in which the elastic yarn 14 is stretched, and is contracted in a relaxed state after knitting. The degree of extension of the ground yarn 14 when the chain knitting 12 is knitted (that is, the ratio of the length when stretched to the length of the relaxed state) is necessary for the formation (that is, length and height) of the pile loop 18b described later. It is set to a value that provides a degree of contraction. The degree of elongation depends on the material and thickness of the ground yarn 14. For example, when an FTY yarn having a 40 denier polyurethane yarn is used, it is preferably 200% or more.

  In this embodiment, the ground yarns 14 of all the chain stitches 12 are composed of stretch yarns described later, but the present invention is not limited to this. That is, the chain knitting 12 may be knitted with non-stretchable yarn for each predetermined wale. In this case, it is not necessary to apply tension similar to that of the stretchable yarn to the non-stretchable yarn.

  As described above, the ground yarn 14 is a stretchable yarn and includes at least a polyurethane-based stretch yarn (so-called spandex). Specifically, polyurethane filament twisted yarn (FTY), covering yarn obtained by wrapping yarn of other material (for example, nylon) around polyurethane filament, these polyurethane stretch yarn and non-stretch yarn are aligned. Such as yarn. The non-stretchable yarn is, for example, a spun yarn such as cotton or rayon, or a filament yarn such as nylon, polyester, or acrylic. The thickness of the ground yarn 14 is, for example, 10 to 420 denier when the ground yarn 14 is a polyurethane filament twisted yarn. In addition, as long as the elasticity equivalent to a polyurethane-type elastic thread is obtained, the elastic thread may be a thread of other materials. Examples of such yarn include polyether ester-based or polyester-based stretch yarn.

  The pile yarn 18 knits a pile knitted fabric 17 having a stitch 18a and a pile loop 18b. The pile yarn 18 is knitted to have a structure of 20/20/22/44/46/46/44/22 //, for example, as shown in FIG. The pile yarn 18 of this embodiment is, for example, a filament yarn such as polyester or nylon, and the thickness thereof is, for example, 20 to 210 denier. A spun yarn can also be used as the pile yarn 18.

  The pile loop 18b is knitted in a zigzag manner along the course direction Dc, straddling the chain stitch 12 of at least one wale, and straddling the stitches of the chain stitch 12 of at least two courses. In addition, from the viewpoint of maintaining the function as a pile loop, the number of wales and the number of courses of the chain knitting 12 that the pile loop 18b straddles are preferably 1 to 5 wales and 2 to 12 courses, respectively. However, the number of wales and the number of courses can be changed according to the density of the stitches of the chain stitch 12 (driving density).

  As described above, the chain stitch 12 contracts after knitting. The pile loop 18b is formed with this contraction. Since the pile loop 18b straddles at least two courses of the chain knitting 12, it is possible to set a sufficient length (size) as long as there is no hindrance to the knitting. That is, by setting the length of the pile loop 18 to an appropriate value, the pile loop 18 can be prevented from interfering with the extension of the chain stitch 12. In another aspect, by setting the dimension (length) of the pile loop 18 to an appropriate length, the pile loop 18b can maintain its function even when the chain braid 12 is most stretched.

  The degree (height) at which the pile loop 18b protrudes can be determined according to the degree of contraction of the base yarn 14, that is, the tension of the base yarn 14 when the chain knitting 12 is knitted. For example, when the tension of the ground yarn 14 is increased at the time of knitting under the condition that the position of the stitch 18a is the same, the height protruding from the chain knitting 12 to the outside (front side) increases. Conversely, when the tension of the ground yarn 14 is lowered, the height protruding from the chain knitting 12 to the outside (front side) is lowered.

  Since the conventional pile loop is knitted in the stitches of the course where both ends are adjacent to each other, the pile loop extends uniformly in the substantially wale direction Dw. Therefore, the approach direction of the male surface fastener that is easily locked to the pile loop is likely to be unevenly distributed in the course direction Dc and a direction close thereto. On the other hand, the pile loop 18b of the present embodiment straddles at least two course stitches as described above, and is inclined in the course direction Dc as compared with the conventional pile loop. Therefore, the uneven distribution as described above can be reduced with respect to the entry direction of the male hook-and-loop fastener that is easily locked to the pile loop. That is, it becomes possible to appropriately lock (entangle) the male surface fastener approaching from the wale direction Dw.

  Both ends of the pile loop 18b are continuously overlapped with one chain braid 12 respectively. That is, the pile yarns 18 at both ends of the pile loop 18b form at least two stitches 18a that are continuously arranged on one chain stitch 12. Each stitch 18 a is intertwined with the corresponding stitch of the chain stitch 12. In addition, the entanglement between the ground yarn 14 and the pile yarn 18 becomes stronger due to the shrinkage of the chain stitch 12. As a result, the movement of the pile yarn 18 through each stitch 18a is suppressed, and the pile loops 18b located on both sides of the pulled pile loop 18b are not pulled out through the stitch 18a. That is, the pile loop is difficult to be unwound from the warp knitted fabric, durability as a pile fabric is improved, and wrinkles are hardly generated on the warp knitted fabric. Furthermore, heat fusion and resin processing for preventing the pile yarn from coming off are unnecessary.

  In the present embodiment, the stitches 18a of the pile yarn 18 may be either closed or open. Further, the stitch 18a may be either forwardly or reversely applied to the stitch 14a of the ground yarn 14. In other words, at the same position, the overlap direction of the ground yarn 14 constituting the chain knitting 12 and the overlap direction of the pile yarn 18 constituting the stitch 18a may be the same direction or may be opposite to each other. That is, the pile yarn 18 may have a closed structure shown in FIG. 1 or may have an open structure such as a 20/02/22/44/46/64/44/22 // structure shown in FIG. .

  The number of wales of the chain knitting 12 into which one pile yarn 18 is knitted is arbitrary. That is, 20/20/22/44/46/46/66/88/810 (8-10) / 810 (8-10) / 88/66/64/64/44/22 // shown in FIG. As in the structure, one pile yarn 18 may be knitted into the chain knitting 12 having 3 or more wales. Moreover, an organization in which closed eyes and open eyes are mixed may be used, such as this organization.

  The number of wales of the chain knitting 12 straddled by each pile loop 18b is Nw1, and the knitting of the chain knitting 12 between the pile loops 18b, 18b (stitches 18a, 18a) composed of two pile yarns 18, 18 adjacent to each other in the wale direction Dw. When the number is Nw2 (see FIG. 1), the wal number Nw1 may be set to a value larger than the wal number Nw2. For example, in the pile knitted fabric 17 of FIG. 1, the number of wales Nw1 = 1 and the number of wales Nw2 = 0, which satisfy this condition. When this condition is satisfied, the pile loop 18b can be formed with a desired density, and the rows that do not intersect the pile loop 18b along the course direction Dc (in other words, only the stitches 18a are arranged along the course direction Dc). Column) can be eliminated. As a result, the male surface fastener (hook) (not shown) or the like can be easily locked and the adhesion strength can be improved.

  The insertion yarn 16 is inserted into the chain knitting 12 and the pile knitted fabric 17. In other words, it is inserted into each stitch 14a, 18a of the ground yarn 14 and the pile yarn 18. The insertion yarn 16 connects the chain knitting 12 in the wale direction Dw and connects the pile knitted fabric 17 to the chain knitting 12. Further, the insertion yarn 16 is zigzag inserted into the chain stitch 12 along the course direction Dc. FIG. 1 shows a structure of 00/66 // as an example of this structure, and is inserted into the chain stitch 12 so as to straddle the chain stitch 12 of at least one wale. The structure of the insertion thread 16 may be 66/00 // which is reversed with respect to the chain braid 12 of FIG. 1, or other structures (for example, 00/66/00/44 //, 00/66 / 44/1010/44/66 //). Furthermore, as long as the connection of the chain stitches 12 is not hindered, the insertion portion of the insertion yarn 16 may be omitted by inserting the insertion yarn 16 1 in 1 out. In addition, the structure | tissue of the insertion thread | yarn 16 is knitted similarly with respect to all of each structure | tissue (refer FIGS. 1-3) of the ground yarn 14 and the pile yarn 18 mentioned above.

  The insertion yarn 16 is, for example, a spun yarn such as cotton or rayon, or a filament yarn such as polyester or nylon. The thickness of the insertion yarn 16 is 16 to 80 in the case of spun yarn, and 20 to 300 denier in the case of filament yarn. There is no limitation on the number of twisted yarns constituting the spun yarn. That is, when a spun yarn is used for the insertion yarn 16, the spun yarn may be a single yarn or a twin yarn, or may be composed of a larger number of twisted yarns.

  As described above, while the warp knitted fabric of the present embodiment is knitted by the warp knitting machine, the chain knitting 12 is knitted while the base yarn 14 is stretched. As a result, the chain stitch 12 in the relaxed state after knitting contracts more than during knitting. By this contraction, the warp knitted fabric contracts in any of the course direction Dc and the wale direction Dw, thereby imparting stretchability.

In order to increase the contraction force in the tension state (that is, in the state where the warp knitted fabric is stretched), as shown in FIG. 1, the auxiliary yarns 22 are inserted into the zigzag along the course direction Dc for each chain knitting 12. May be. The auxiliary yarn 22 is a stretchable yarn made of the same material as the base yarn 14, for example, 00/22 //, 00/00/22/22 //, 00/00/00/22/22/22. // inserted in tissues such as The auxiliary yarns 22 may be inserted into all the chain stitches 12, or the number of the chain stitches 12 to be inserted may be adjusted in accordance with a desired contraction force such as 1 in 1 out. When the auxiliary yarn 22 is inserted, the vertical relationship between the insertion yarn 16 and the auxiliary yarn 22 may be reversed. That is, through the inserting yarn 16 reed _{L 3} is a tissue of FIG 1, and, although through the auxiliary yarn 22 in the guide bar _{L 4,} the reed _{L 3} through the auxiliary thread 22, and, the inserting yarn 16 to the guide bar _{L 4} You may go through.

The warp knitted fabric of the present embodiment has the following effects in addition to the effects described above.
The warp knitted fabric of the present embodiment includes a plurality of chain knitted fabrics knitted with a ground yarn having elasticity. This chain knitting is stretched during knitting and contracts after knitting. Therefore, the warp knitted fabric after knitting is given extensibility in both the wale direction and the course direction as the chain knitting contracts. Furthermore, this contraction forms a pile loop on the surface. That is, a pile warp knitted fabric having elasticity can be provided.

  Further, in a conventional knitted fabric in which stretch yarns are simply inserted in a zigzag pattern, so-called slip-in occurs in which the stretch yarns are buried in the knitted fabric after the knitted fabric is cut. On the other hand, in the warp knitted fabric of the present invention, the chain knitting constituting the ground structure is knitted with the stretch yarn itself. Moreover, by extending the stretch yarn during the knitting of the chain knitting, the chain knitting after the knitting contracts, and as a result, is tightly tightened. Therefore, the slip-in of the elastic yarn is difficult to occur and the cut portion is difficult to unravel. Since the cut portion is difficult to unravel, the durability of the warp knitted fabric is improved.

  Since the ground yarn itself constituting the ground texture of the warp knitted fabric has elasticity, it is not necessary to intentionally form a fold for imparting elasticity to the warp knitted fabric. That is, the warp knitted fabric of this embodiment can be made thin. When the present invention is used as a bandage, the thickness after winding can be reduced, so that a good appearance can be obtained and interference with clothes can be reduced.

(Modification)
A modification of this embodiment will be described. In this modification, non-stretchable yarn such as filament yarn or spun yarn is used for the ground yarn 14, and the above-mentioned stretchable yarn is used for the auxiliary yarn 22. The filament yarn is, for example, a nylon yarn or a polyester yarn. The spun yarn is, for example, cotton yarn or rayon yarn. In this modified example, the auxiliary yarn 22 imparts stretchability to the warp knitted fabric. Other configurations such as the knitting pattern are the same as those in the above-described embodiment.

  In this modification, the chain knitting 12 is knitted with a driving density of 5 to 25 courses per 1 cm, so that a stitch 12a having a relatively high density is formed. On the other hand, as in the above-described embodiment, the pile loop 18b straddles the chain stitch 12 of at least one wale and straddles the stitches of the chain stitch 12 of at least two courses. Accordingly, even if the driving density of the chain braid 12 is high, the pile loop 18b has a sufficient length for forming the loop. In the modification, the pile loop 18b is formed by the shrinkage of the chain knitting 12 accompanying the relaxation of the auxiliary yarn 22 after knitting.

  Further, the stitch 18a is continuously overlapped with one chain stitch 12. Therefore, although the pile yarn 18 is not tightened by the expansion and contraction of the ground yarn 14 itself, the entanglement between the ground yarn 14 and the pile yarn 18 becomes strong as in the above embodiment. As a result, the movement of the pile yarn 18 through each stitch 18a is suppressed, and the pile loops 18b located on both sides of the pulled pile loop 18b are not pulled out through the stitch 18a. That is, the pile loop is difficult to be unwound from the warp knitted fabric, durability as a pile fabric is improved, and wrinkles are hardly generated on the warp knitted fabric. Furthermore, heat fusion and resin processing for preventing the pile yarn from coming off are unnecessary.

  In the warp knitted fabric of this embodiment, the chain stitch 12 may be knitted so as to avoid the stitches 18a of the pile yarn 18. For example, in the warp knitted fabric of FIG. 1, the chain knitted fabric 12 has a structure of 00/00/02/20 //, the pile knitted fabric 17 has a stitch 18a of the pile yarn 18 and the ground yarn 14 (chain knitted fabric). 12) The knitting is performed so as to be located at a portion where the stitch 14a is not formed. Therefore, since the stitch 14a of the base yarn 14 and the stitch 18a of the pile yarn 18 do not overlap, the surface of the warp knitted fabric can be made smoother than the structure of FIG.

  The present invention is not limited to the above-described embodiment, but is shown by the description of the scope of claims, and further includes all modifications within the meaning and scope equivalent to the description of the scope of claims.
