Description

  The present invention relates to a warp knitted fabric for apparel that has tension and waist and is excellent in shape retention.

  Interlining is used in a wide range of areas such as suits, trousers, work clothes, coats, and accessories such as ties and hats for the purpose of shape retention and silhouette adjustment. In addition, the kind of fabric forming the interlining is formed of a nonwoven fabric, a woven fabric, a knitted fabric, and the like, and each has advantages and disadvantages, so that it is appropriately selected and adopted according to the required performance of the product to be used.

  For example, the nonwoven fabric as proposed in Reference 1 is thin, excellent in form stability, and relatively inexpensive, so it is often used as a garment for clothing, but has excellent form stability, There is a problem that drape is lacking and it is difficult to follow the deformation of the outer surface. Further, in the case of a woven fabric or a weft insertion tricot knitted fabric as proposed in Patent Document 2 or Patent Document 3, since the constituent yarns are not adhesively bonded to each other, they are excellent in drape and follow the deformation of the outer material. Although it is easy, it is a problem that it is inferior to a nonwoven fabric in terms of form retention.

  In addition, in the interlining for the waistline of school clothes, trousers, etc., it is particularly tight and has a waist, and a high degree of form stability is required, and the normal fabric structure as described above is insufficient. For this reason, a soft resin sheet or other fabric is laminated on one side of the fabric and used.

  However, if materials with different thermal properties are bonded together on the front and back of the interlining, problems such as the possibility of deformation when exposed to high temperatures with an iron or the like, and the cost of laminating are added, increasing the manufacturing cost. There's a problem.

Japanese Patent Laid-Open No. 10-008311 Japanese Patent Laid-Open No. 10-060748 Japanese Patent Laid-Open No. 08-027643

  In view of the above-described problems, the present invention is to provide an interlining having a tightness and a waist and having excellent shape stability, and particularly suitable for use as a collar for school uniforms, etc., at a low manufacturing cost. .

  Means employed by the present inventor for solving the above technical problem will be described with reference to the accompanying drawings.

  That is, the present invention is knitted with a warp knitting structure comprising a connecting yarn that unifies the front knitted fabric and the back knitted fabric, and the front knitted fabric and the back knitted fabric, and a part or all of the connecting yarn is thermoplastic. The connecting yarn was completed by inserting the connecting yarn into a sinker loop of the front stitch constituting the front knitted fabric and a sinker loop of the back stitch constituting the back knitted fabric, respectively.

  Moreover, the said connection thread | yarn can employ | adopt the technical means which consists of 2 or more types from which the swing width to the wale direction for every knitting course differs.

  Further, the connecting yarn may employ a technical means in which the sheath portion is a core-sheath composite yarn having a low melting point polymer and a core portion made of a high melting point polymer.

  Furthermore, the connecting yarns can be entangled with each other, and technical means for adhering the connecting yarns at the entanglement point can be adopted.

Furthermore, technical means in which a part or all of the front knitted fabric and / or the back knitted fabric has a mesh structure can be adopted.

  Furthermore, technical means using colored yarn for a part or all of the front knitted fabric and / or the back knitted fabric can be employed.

  In the present invention, the front knitted fabric and the back knitted fabric, and the warp knitting structure comprising the connecting yarn that integrates the front knitted fabric and the back knitted fabric are knitted, and a part or all of the connecting yarn is heated. A double-sided warp knitted fabric in which the connecting yarn is inserted into a sinker loop of a front knitted fabric constituting the front knitted fabric and a sinker loop of a back knitted fabric constituting the back knitted fabric, the same structure on both sides Therefore, since there is no wrinkle that curls the knitted fabric, it is easy to handle, and even if it is used as the core material of clothes, the form does not change.

  Also, since the warp knitted fabric of the present invention is a double-sided warp knitted fabric, it is thick and stretched and has a waist. It can be applied as a core material for waists and pants.

  In addition, since the connecting yarn is not knitted into the front knitted fabric and the back knitted fabric, but is integrated by being inserted into the sinker loop of the front knitted fabric and the back knitted fabric, a low melting point polymer yarn can be used as the connecting yarn. The low melting point polymer component does not appear on the front and back surfaces of the warp knitted fabric, and there is no concern about the problem that the low melting point polymer component oozes from the surface material even when heat setting is performed at a temperature higher than the melting temperature of the low melting point polymer yarn.

  In addition, since the connecting yarns with different swing widths are crossed in different oblique directions and the front knitted fabric and the back knitted fabric are integrated, shear deformation of the front knitted ground and the back knitted fabric is suppressed, and is excellent. Demonstrate morphological stability.

  In addition, using a core-sheath composite yarn composed of a low-melting-point polymer sheath and a high-melting-point core in the connecting yarn, and bonding in an entangled state between the connecting yarns of different swings, it becomes highly rigid. It becomes a warp knitted fabric with even higher tension and waist.

  Furthermore, in the front knitted fabric and / or the back knitted fabric, the sewing process can be made more efficient by marking the cutting line and the center position for sewing using a part or all of the colored yarn.

It is a perspective view which shows the knitted fabric structure of embodiment of this invention. It is a knitting | organization organization chart of embodiment of this invention.

  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

  FIG. 1 shows a knitted fabric structure for explaining a warp knitted fabric of the present invention, wherein reference numeral 1 is a warp knitted fabric of the present invention, and reference numeral 2 is a front side stitch row f1, f2, consisting of front side chain knitting yarns 4. The front knitted fabric 2 is composed of f3, f4,... and the weft insertion yarn 6. Reference numeral 3 is a back surface composed of the back side stitch rows b1, b2, b3, b4,. The knitted fabric 3 is shown.

The horizontal insertion threads 6 and 7 are each shown as an example of horizontal insertion of 5 stitches. However, it is sufficient that the horizontal insertion is more than 2 stitches. It is preferable because it can be stretched on the knitted fabric 1 and the waist effect can be increased.

A connecting yarn 8 having a one-needle insertion structure and a connecting thread 9 having a two-needle insertion structure are arranged between the front knitted fabric 2 and the back knitted fabric 3, and the connecting yarns 8 and 9 are connected to the chain stitch structure of the front knitted fabric 2. Are inserted into the sinker loop of the chain stitch structure of the back knitted fabric 3 and the back knitted fabric 3 to connect the front knitted fabric 2 and the back knitted fabric 3 together, and the connecting yarns 8 and 9 appear on the front and back of the warp knitted fabric 1 Not knitted fabric structure.

  That is, the connecting yarn 8 of the one-needle insertion structure is zigzag in the course direction while connecting the front side stitch rows f1, f2, f3, f4... And the back side stitch rows b1, b2, b3, b4. On the other hand, the connecting yarn 9 of the two-needle insertion structure is inserted into the back side stitch rows b1, b2, b3, b4... Facing the front side stitch rows f1, f2, f3, f4. The front knitted fabric 2 and the back knitted fabric 3 and the two different connecting yarns 8 and 9 are connected to each other like a truss structure. The movement of the shear deformation of the knitted fabric 2 and the back knitted fabric 3 is suppressed, and a warp knitted fabric having a very stable shape is obtained.

  The insertion structure of the connecting yarns 8 and 9 is not limited to the combination of one-needle insertion and two-needle insertion, but may be one-needle insertion and three-needle insertion, or a combination of three types as long as the truss structure can be oriented. . Further, the yarn types to be used are not particularly limited to the chain knitting yarns 4 and 5 and the weft insertion yarns 6 and 7 other than the connecting yarns 8 and 9, but at least the connecting yarns 8 and 9 are made of thermoplastic fiber yarns. Since the two types of connecting yarns 8 and 9 are heat-set in a state where they are intertwined with each other, the warp knitted fabric itself has increased rigidity. Therefore, it is preferable to use a thermoplastic fiber yarn as the connecting yarn.

  Since the warp knitted fabric 1 of the present invention has a double-sided warp knitted fabric structure with the same front and back as described above, there is no wrinkle that curls the knitted fabric, and the form changes even when used as a garment core. In addition, since the connecting yarns of different swing widths are crossed in directions different from each other and the front knitted fabric and the back knitted fabric are integrated, the shear deformation of the front knitted fabric and the back knitted fabric is prevented. It is suppressed and has excellent morphological stability.

  The connecting yarns 8 and 9 of the warp knitted core 1 of the present invention use a core-sheath composite yarn in which the sheath is made of a low-melting polymer and the core is made of a high-melting polymer. As a result, the connecting yarns 8 and 9 are intertwined with each other and the cross-knitting portions of the chain knitting yarns 4 and 5 with the sinker loop are firmly bonded with a low melting point polymer, and the rigidity is further increased. The warp knitted fabric 1 that has it can be obtained.

  The core-sheath composite yarn is made of a thermoplastic polymer such as polyester, polyamide, or polyethylene, and among them, a polyester thermoplastic polymer having a high elastic modulus is preferable. The low melting point polymer having a melting point of about 100 to 180 ° C. is preferably a composite yarn that is melt-spun with a polymer having a sheath portion that is higher than the melting point of the low melting point polymer by about 20 ° C. or more. A composite yarn in which a fiber yarn made of a polymer is used as a core and a fiber yarn made of 100% low melting point polymer is covered may be used.

  Even if a composite yarn containing a low melting point polymer is used for the connecting yarns 8 and 9 of the warp knitted core fabric 1 of the present invention, the connecting yarns 8 and 9 appear on the surface of the front knitted fabric 2 and the back knitted fabric 3. Since it remains inside the warp knitted interlining 1, there is no concern that the low melting point polymer will ooze out on the surface of the garment even if the garment or the like using the interlining is subjected to a high temperature treatment.

  The warp knitted fabric 1 of the present invention can be manufactured with a normal double raschel warp knitting machine having two needle beds, and the gauge, the course density, the fineness of the knitting yarn, etc. of the knitting machine to be used are required. The warp knitting core 1 is appropriately selected depending on the basis weight, thickness, rigidity, etc. As preferred ranges, the knitting machine gauge is 9 to 36 gauge, the course density is 10 to 40 course / 25.4 mm, The fineness of the yarn is preferably in the range of 30 to 1000 dtex.

  Further, the front knitted fabric 2 or the back knitted fabric 3 of the warp knitted fabric 1 of the present invention can be made into a mesh structure, and is effective as a garment for clothing that requires air permeability, This is a preferred embodiment because it also has an effect on reducing the basis weight.

Furthermore, colored yarn can be used for part or all of the front knitted fabric 2 or the back knitted fabric 3 of the warp knitted fabric 1 of the present invention. If a colored thread is arranged as a mark of the place, cutting and sewing can be performed without measuring each time during sewing, and the sewing work can be made efficient.
