Description

  The present invention relates to a raschel stretch lace fabric and a knitted lace product.

  A conventional knitted lace fabric is disclosed in, for example, Patent Document 1. In this lace knitted fabric, the covering yarn is knitted in the scalloped portion. The covering yarn is composed of a core yarn having heat melting property and a covering yarn which is a thermoplastic synthetic fiber yarn. By heating the knitted lace fabric after knitting, a part of the core yarn of the covering yarn is melted and the melt oozes out from between the coated yarns. The melt is solidified by adhering other adjacent yarns. This prevents fraying at the scalloped portion of the knitted lace product.

Japanese Patent Laid-Open No. 11-81073

  In the lace fabric of the prior art, the thermal bonding yarn is knitted only in the scalloped portion, and the scalloped portion and the other portion are knitted with different yarns. In such a configuration, even if knitted into the same knitting structure, the visual and tactile uniformity cannot be obtained, and the aesthetics and texture are lowered. On the other hand, it is conceivable to knit the thermal bonding yarn not only to the scalloped part, but when the thermal bonding yarn is knitted to the whole, the exuded melt adheres to the surface of the coated yarn and spreads throughout. Flexibility is impaired, and the melt, not the coated yarn, comes into contact with the skin, and the texture is deteriorated. Further, with such a configuration, a stretch lace fabric cannot be realized. Conversely, a configuration in which no thermal bonding yarn is used is also conceivable. However, in such a configuration, the yarns are easily displaced at all the intersections of the yarns, and the lattice may be distorted and the appearance may be impaired. There is.

  Accordingly, an object of the present invention is to provide a raschel stretch lace knitted fabric and a knitted lace product having a good aesthetic appearance and a good texture.

In addition, a part of the intersection of the chain knitting yarn and the stretch yarn is bonded, and a large positional deviation between the chain knitting yarn and the stretch yarn is prevented, and the lattice distortion caused by the positional deviation between the chain knitting yarn and the stretch yarn is prevented. Is prevented. For example, even if an external force due to a manufacturing process such as sewing or cutting of a knitted lace fabric or an external force due to use such as wearing or washing is applied, distortion of the lattice is prevented and the shape of the lattice is maintained. A good knitted lace fabric can be obtained, and the excellent beauty can be maintained for a long time. Moreover, since the chain knitting yarn and the stretch yarn are bonded by utilizing the adhesiveness of the chain knitting yarn knitted to the entire lace knitted fabric, it is not a configuration in which different yarns are used partially, but visually and tactilely.

In addition, as in the case where all the crossing portions of the chain knitting yarn and the stretch yarn are bonded, the stretchability and flexibility are not impaired, and the knitted lace fabric that maintains the stretchability and has a good texture. can get. Here, the texture means the touch, and the good texture means the touch having flexibility. Thus, a stretch lace knitted fabric having good appearance and good texture can be obtained.

  According to the second aspect of the present invention, since a part of the intersecting portions of the chain knitting yarns are bonded to each other, a large misalignment between the chain knitting yarns is prevented, and the misalignment between the chain knitting yarns is prevented. The resulting lattice distortion is prevented. Moreover, since the chain knitting yarn and the stretch yarn are bonded by utilizing the adhesiveness of the chain knitting yarn knitted to the entire lace knitted fabric, it is not a configuration in which different yarns are used partially, but visually and tactilely. Unity, and the aesthetics and texture are not impaired.

  According to the third aspect of the present invention, the adhesion rate at the intersection between the chain knitting yarn and the stretch yarn is higher than the adhesion rate at the intersection between the chain knitting yarns. As a result, the adhesion rate of the entire crossing portion of the yarn can be kept low and the flexibility can be maintained, and the misalignment between the chain knitting yarn and the stretchable yarn, which easily affect the lattice distortion, can be prevented as much as possible, and the aesthetic appearance can be maintained.

FIG. 1 is a knitting organization chart showing a part of a Russell stretch lace knitted fabric (hereinafter simply referred to as “lace knitted fabric”) 20 according to an embodiment of the present invention. FIG. 2 is a knitting structure diagram showing the knitted lace fabric 20 with yarns other than the chain knitting yarn 21 and the stretch yarn 23 omitted. 1 and 2 schematically show a knitted structure for easy understanding, and the actual knitted structure of the lace knitted fabric 20 includes a first loop-shaped portion 24 and a second loop. The curved portion 25 has a small radius of curvature, and the yarns 21, 22, and 23 are in close proximity or in contact with each other. Further, in FIG. 1, for easy understanding, the chain knitting yarn 21 is hatched with a slanting left-down line, and the stretchable yarn 23 is hatched with a slanting line sloping down to the right. FIG. 2 shows the yarns 21 and 23 with the thickness omitted.

  In the present invention, the knitted fabric knitted by the yarns 21 to 23 is referred to as a precursor knitted fabric. The lace knitted fabric 20 is obtained by heating a precursor knitted fabric. Further, a product manufactured using the knitted lace fabric 20 is referred to as a knitted lace product.

  The lace knitted fabric 20 is a warp knitted fabric, a raschel knitted fabric that is raschel knitted, and a stretch knitted fabric having elasticity. The knitted lace fabric 20 is knitted by a yarn including a chain knitting yarn 21, an insertion yarn 22, and a stretchable yarn 23. A plurality of lattices are formed by the respective yarns 21 to 23, and a plurality of transparent yarns surrounded by the respective lattices. A hole is formed. In this lace fabric 20, a lace pattern is formed by the shape and arrangement of the lattice. The knitted lace fabric 20 has a pattern portion having a dense amount of yarn arranged per unit area and a base portion having a sparse amount of yarn arranged per unit area. A pattern is formed by the shape and arrangement of the parts. Such a knitted lace fabric 20 with a patterned pattern is used for producing a knitted lace product such as a female underwear.

  As shown in FIG. 1, the knitted lace fabric 20 has a chain knitting yarn 21 that forms a chain knitted fabric 19 of a Russell knitting having a plurality of loop-shaped portions 24 and 25, and a stretchability that elastically expands and contracts. An elastic yarn 23 is provided for knitting the chain stitch structure 19 to give the chain stitch structure 19 stretchability. The knitted lace fabric 20 has an insertion yarn 22 and is knitted into the chain stitch structure 19. The chain knitting yarn 21 may be referred to as a warp yarn or a ground knitting yarn. The insertion yarn 22 may also be referred to as a weft yarn.

  Furthermore, in the knitted lace fabric 20, a part of the intersection 50 between the chain knitting yarn 21 and the stretchable yarn 23 is bonded using the adhesiveness of the chain knitting yarn 21. Not all the crossing portions 50 of the chain stitch yarn 21 and the stretchable yarn 23 are bonded, but only a part of the crossing portions 50 are bonded. Further, in the lace knitted fabric 20, a part of the intersecting portion 55 between the chain knitting yarns 21 is bonded to each other using the adhesiveness of the chain knitting yarn 21. Not all the crossing portions 55 of the chain knitting yarns 21 are bonded, but only a part of the crossing portions 55 are bonded. Further, in the lace knitted fabric 20, the adhesion rate of the crossing portion 50 between the chain knitting yarn 21 and the stretchable yarn 23 is higher than the adhesion rate of the crossing portion 55 between the chain knitting yarns 21. The adhesion rate is the number of crossing portions to be bonded out of the total number of crossing portions. In the knitted lace fabric 20, the intersection of the chain knitting yarn 21 and the insertion yarn 22 may be bonded, but in the present embodiment, it is hardly bonded.

FIG. 3 is a front view showing a part of the chain stitch yarn 21 before knitting. FIG. 4 is a front view showing a part of the chain knitting yarn 21 knitting the knitted lace fabric 20. In the state where the knitted lace fabric 20 is knitted, the chain knitting yarn 21 has a shape as shown in FIG. 1 and FIG. 2, but FIG. It shows with. The chain stitch yarn 21 is a yarn in which a covering yarn 31 is spirally wound around a core yarn 30 having elasticity. The core yarn 30 is a single fiber yarn (filament yarn) made of a thermoplastic synthetic resin, and is made of, for example, polyester polyurethane. The covering yarn 31 is a long fiber yarn (filament yarn) composed of a plurality of long fibers made of synthetic resin, and is made of, for example, polyamide (trade name: nylon).

In the state before knitting, the chain yarn 21 is covered with the covering yarn 31 so that the covering yarns 31 come into contact with each other and the core yarn 30 is not exposed as shown in FIG. The chain knitting yarn 21 is knitted in a stretched state as shown in FIG. 4 using the stretchability of the core yarn 30. When the chain knitting yarn 21 is stretched, a spiral gap is formed between the covering yarns 31, and the core yarn 30 is exposed from the gap.

  The insertion yarn 22 is a long fiber yarn (filament yarn) composed of a plurality of long fibers made of synthetic resin, and is made of, for example, polyamide (trade name: nylon), rayon, polyester, or the like. The stretchable yarn 23 is also called a spandex, is a single fiber yarn (filament yarn) made of a material having stretchability, and is made of, for example, polyester-based polyurethane.

  The core yarn 30 of the chain knitting yarn 21 and the stretch yarn 23 are both made of polyester polyurethane, but are made of different types of polyester polyurethane, and the melting temperature of the core yarn 30 is higher than the melting temperature of the stretch yarn 23. Is low. The melting temperature of the core yarn 30 is lower than the melting temperatures of the coated yarn 31, the insertion yarn 22, and the stretchable yarn 23, and has thermoplasticity. Thus, the chain stitch yarn 21 is a yarn including the core yarn 30 made of a material having a low melting temperature.

  FIG. 5 is a flowchart showing an example of a manufacturing process of the knitted lace fabric 20 of the present embodiment. First, in step a0, selection of each yarn used for knitting the lace knitted fabric 20, determination of a pattern to be formed on the lace knitted fabric 20, and design of the knitted fabric for forming a desired knitted structure are completed. When the preparation for the knitted fabric is completed, the process proceeds to step a1 and the production of the lace knitted fabric 20 is started.

  In step a1 which is a knitted fabric knitting process, a precursor knitted fabric which is a precursor of the lace knitted fabric 20 is knitted using a knitting machine which is a Russell knitting machine. The knitting machine knits the yarns 21 and 22 such as the thermal bonding yarn 23 into the chain knitting yarn 21 in accordance with the knitting order designed in step a0, and has a knitting structure similar to that of the lace knitted fabric 20 shown in FIG. Knit the precursor knitted fabric.

  In the precursor knitted fabric, the chain knitting yarn 21 and the stretch yarn 23 have stretchability. The knitting machine performs the knitting operation in a state where the stretchable yarn is stretched. The precursor knitted fabric is shrunk after knitting due to the restoring force of the yarn knitted in the stretched state, and when this stretchability is maintained up to the lace knitted fabric 20, the lace knitted fabric 20 has stretchable lace. Become a knitted fabric. When the knitting of the precursor knitted fabric is thus completed, the process proceeds to step a2.

  In step a2, which is a heating process, the precursor knitted fabric knitted in step a1 is equal to or higher than the melting temperature of the core yarn 30 of the chain knitting yarn 21, and the melting temperatures of the yarns 22, 23, 31 other than the core yarn 30 are melted. Heat to a temperature below. In heating the precursor knitted fabric in step a2, the precursor knitted fabric is stretched, and the chain knitting yarn 21 is heated in a stretched state as shown in FIG. As a result, the core yarn 30 of the chain knitting yarn 21 is heated and melted in a partially exposed state.

  Therefore, the chain knitting yarn 21 and the stretchable yarn 23 are bonded to each other only at the intersecting portion 50 where the stretchable yarn 23 is in contact with the exposed portion of the core yarn 30 in the intersecting portion 50 between the chain knitting yarn 21 and the stretchable yarn 23. Is done. Further, the chain knitting yarns 21 are bonded to each other only at the intersecting portion 55 where the exposed portions of the core yarn 30 are in contact with each other among the intersecting portions 55 between the chain knitting yarns 21.

  The core yarn 30 and the stretchable yarn 23 of the chain knitting yarn 21 are different in type, but are both made of polyester-based polyurethane, so that the core yarn 30 is easily bonded by being melted. Further, the core yarns 30 are also easily bonded by melting. On the other hand, the covering yarn 31 of the chain stitch yarn 21 is made of polyamide, and the insertion yarn 22 is made of polyamide, rayon or the like, and is hardly bonded to the core yarn 30. Therefore, only a part of the crossing portions 50 and 55 as described above are bonded, and the crossing portion between the chain stitch yarn 21 and the insertion yarn 22 is hardly bonded. Furthermore, since the crossing portion 55 between the chain knitting yarns 21 is not bonded unless the portions where the core yarn 30 is exposed are in contact with each other, the cross section 55 bonding rate between the chain knitting yarns 21 is equal to the chain knitting yarn 21 and the stretch yarn. It becomes lower than the adhesive rate of the crossing part 50 with 23.

  In this way, the precursor knitted fabric is heated so that a part of the crossing part 50 between the chain knitting yarn 21 and the stretchable yarn 23 is adhered, and a part of the crossing part 55 between the chain knitting yarns 21 is adhered, A knitted lace fabric 20 is formed, and the process proceeds to step a3. In step a3, the formed knitted fabric 20 is scoured or dyed, then heat treatment called final heat set is performed to fix the form, and the manufacturing procedure of the lace knitted fabric 20 is completed. By heating the precursor knitted fabric in step a2, the core yarn 30 of the chain knitting yarn 21 is melted, so that the stretchability is impaired, but the stretchable yarn 23 is heated only below the melting temperature. Can be maintained. Therefore, the lace fabric 20 has stretchability.

  According to such a knitted lace fabric 20 of the present embodiment, the stretch yarn 23 having stretchability is knitted into the chain stitch structure 19 so that the chain stitch structure is stretchable, and thus has stretchability. Lace knitted fabric can be realized. Further, a part of the crossing portion 50 between the chain knitting yarn 21 and the stretchable yarn 23 is bonded, and a part of the crossing portion 55 between the chain knitting yarns 21 is bonded to each other. This prevents misalignment between the chain knitting yarn 21 and the stretch yarn 23 and misalignment between the chain knitting yarns 21, and prevents distortion of the lattice. For example, even if an external force caused by a manufacturing process such as sewing or cutting of a knitted knitted fabric or an external force caused by usage such as wearing or washing is applied, distortion of the lattice is prevented and the shape of the lattice is maintained. A good knitted lace fabric can be obtained, and the excellent beauty can be maintained for a long time.

  In addition, the chain knitting yarn 21 and the stretch yarn 23 are bonded to each other by utilizing the adhesiveness of the chain knitting yarn 21 knitted into the entire lace knitted fabric 20, and the chain knitting yarns 21 are bonded to each other. It is not a configuration in which different yarns are used, but visual and tactile unity is obtained, and aesthetics and texture are not impaired. Further, since the chain knitting yarn 21 in which the core yarn 30 is covered with the covering yarn 31 is stretched and bonded to the exposed portion of the core yarn 30, the surface of the covering yarn 31 is covered with the melt of the core yarn 30. When the lace knitted fabric 20 and the knitted lace product manufactured using the same are brought into contact with the skin, the melt of the core yarn 30 does not come into contact with the skin, and the covering yarn 31 comes into contact with the skin. The coated yarn 31 is a spun yarn as described above, and is a collection of a plurality of single fibers, so that a soft soft feel can be obtained and a good texture can be maintained. Here, the texture means the touch, and the good texture means a touch having flexibility and a soft feeling.

  Further, as in the case where all of the crossing portion 50 between the chain knitting yarn 21 and the stretch yarn 23 and the crossing portion 55 between the chain knitting yarns 21 are bonded, the stretchability and flexibility are not impaired, and the stretch A knitted lace fabric having good texture and good texture can be obtained. Furthermore, the adhesion rate of the crossing portion 50 between the chain knitting yarn 21 and the stretchable yarn 23 is higher than the adhesion rate of the crossing portion 55 between the chain knitting yarns 21. As a result, the adhesive rate of the entire crossing portions 50 and 55 of the yarn is kept low and the flexibility is maintained, and the misalignment between the chain knitting yarn 21 and the stretchable yarn 23 that easily affect the lattice distortion is prevented as much as possible. Can keep. Thus, a stretch lace knitted fabric having good appearance and good texture can be obtained. Moreover, if a knitted lace product is manufactured using such a high quality lace fabric 20, a high quality knitted lace product can be obtained.

  The heating conditions in the heating step described above are set to heating conditions in which the core yarn 30 of the chain knitting yarn 21 is melted and characteristic changes including brittleness of yarns other than the core yarn 30 are prevented. Moreover, it is preferable that the heating conditions in a heating process are set to the heating conditions heated to the temperature which can maintain the form of the core yarn 30 as a thread | yarn. This prevents the melt of the core yarn 30 from appearing on the surface of the knitted fabric and makes it difficult to contact the skin.

  As the heating condition, for example, a heating temperature and a heating time are set. The minimum melting temperature at which the core yarn 30 melts is B1, and the time until softening when heated at the minimum melting temperature is D1. Further, the minimum characteristic change temperature at which the characteristics of the yarns other than the core thread 30 change is B2, and the time until the characteristics change when heated at the minimum characteristic change temperature is D2. In this case, in this embodiment, assuming that the heating temperature in the heating step is B3 and the heating time is D3, B1 <B3 <B2 and D1 <D3 <D2 are set. Furthermore, by setting B3 to a value as close to B1 as possible and D3 to a value as close to D1 as possible, the form of the core yarn 30 can be easily maintained.

  In the present embodiment, a polyester-based thermoplastic polyurethane elastic yarn having a denier of 10 to 300 denier, preferably 10 to 50 denier is used as the core yarn 30. Further, heat treatment is performed at a heating temperature of 170 ° C. or higher and 195 ° C. or lower for a heating time of 30 seconds or longer and 90 seconds or shorter. As a result, the core yarn 30 can be melted and the remaining yarn can be prevented from changing its characteristics.

  For example, when the heating time is constant, if the heating temperature is less than 170 ° C., the adhesive force due to the melted core yarn 30 is reduced. On the other hand, when the heating temperature exceeds 195 ° C., it is difficult to maintain the shape of the core yarn 30 as a yarn, and the characteristics of the yarn other than the core yarn 30 may change. On the other hand, in this embodiment, it can prevent that the problem mentioned above arises by making heating temperature into 170 degreeC or more and 195 degrees C or less as mentioned above.

  As the core yarn 30 becomes thinner, the bonded portion becomes closer to a point contact and becomes smaller and the texture becomes better. As the core yarn 30 becomes thicker, the bonded portion becomes larger and the texture is damaged. In order to make the core yarn 30 thicker and maintain a good texture, it is conceivable to make the coated yarn 31 thicker, but the chain knitting yarn 21 becomes thicker and the sense of sheerness of the lace fabric is impaired. Further, the thinner the core yarn 30 is, the lower the strength is, and the thicker the core yarn 30 is, the higher the strength is. Therefore, when the core yarn 30 is a thin yarn of less than 10 denier, there is a problem that the strength is too small, and when it is a thick yarn of more than 300 denier, the texture is impaired. By setting the core yarn 30 to 10 denier or more and 300 denier or less, there is no shortage in strength and a good texture can be obtained. From the same viewpoint, the core yarn 30 is preferably 10 denier or more and 50 denier or less.

  Further, the knitted lace fabric 20 has an effect of preventing the progress of fraying of the yarn because a part of the intersecting portions 50 and 55 is bonded as described above. Therefore, for example, the knitted lace fabric 20 can be cut into an arbitrary shape so as to be called a motif cut and a free cut.

  FIG. 6 is a knitting organization chart showing a knitted lace fabric 20A according to another embodiment of the present invention. In FIG. 6, yarns other than the chain stitch yarn 21 and the stretch yarn 23 are omitted. In FIG. 6, the thickness of each of the yarns 21 and 23 is omitted. The knitted lace fabric 20A in FIG. 6 is similar to the knitted lace fabric 20 in FIGS. 1 to 5, and the same reference numerals are given to the corresponding parts, only different configurations are described, and the description of the same configurations is omitted. . The knitted lace fabric 20 of FIGS. 1 to 5 has a configuration in which the run stopper 42 is formed as shown in FIG. 2, but the knitted lace fabric 20A of FIG. As shown in FIG. 2, the run stopper 42 is not provided. Further, as an embodiment of the present invention, a configuration having a small number of run stoppers 42 may be employed.

  In the knitted lace fabric 20A of the present invention, as described above, a part of each of the intersecting portions 50 and 55 is bonded, and fraying of the yarn can be prevented. It is possible. If the configuration having no or less run stop portions 42 is used, the crossing of the chain knitting yarn 21 can be eliminated or reduced, the appearance can be improved, and the quality can be improved.

  The above-described embodiment is merely an example of the present invention, and the configuration can be changed. For example, the material of each thread | yarn 21-23 can be changed suitably.
