Description

  The present invention relates to a middle material knitted by a warp knitting machine, and particularly has a firmness and stiffness, is a warp knitted fabric useful as a batting material such as bedding and sports clothing that contains air and is light and easy to wash and quick dry. About.

  Conventionally, as bedding and household materials, there are foamable resins, fiber cushion materials obtained by binding the constituent fibers of a fiber web with an adhesive, cotton, feathers, and the like. Feathers are excellent as a medium material because they are excellent in heat retention, lightweight, easy to follow the body, and bulky, but they are difficult to wash out because they are difficult to blow out through the seams of clothes and side fabrics. Therefore, the applicant of the present application has intensively developed a batting material that is easy to mass-produce and has excellent heat retention that can be washed at home (Patent Document 1).

Japanese Patent No. 6128720

  Conventional foam materials and foamable resins used as cushion materials are excellent in heat retention, but are not easy to wash and cannot be kept clean. It also takes time to dry after washing. Furthermore, the mold is deformed and the inner material is biased by washing. Further, if the filling amount is increased in order to improve the heat retaining property, the weight of the entire garment increases and becomes bulky, resulting in poor usability.

  Feathers are an excellent material for bedding, but are not easy to wash and dry. Further, the batting sheet of Patent Document 1 is excellent in heat retaining properties and easy to wash at home, but it has a room for improvement in terms of shape stability and quick drying, although it swells in a cotton shape and is excellent in flexibility.

  Therefore, an object of the present application is to provide a bedding material and a batting material of clothing that are thin and lightweight, easy to wash, quick drying, and particularly excellent in shape stability.

  A warp knitting machine having a weft insertion function is used to knit a net-like base fabric with coarse stitches using only chemical fiber multifilament yarns, and an elastic yarn is inserted to knitting a warp knitted fabric for medium material It is.

  Since it is knitted using only multifilament yarn of chemical fiber, it can be washed and has quick-drying properties. Since it is easy to wash and dry, the bedding or clothing can be kept clean at all times, and it is useful for home use, as a medical field, or as an intermediate material for sports clothing.

  Although it can be knitted into an ultrathin fabric, it has a firmness and stiffness and is not easily swayed by repeated loading, and is excellent in shape stability against washing and drying. Since it is in the form of a cloth, unlike medium materials such as cotton and feathers, it does not cause severing or wiping (the middle material comes out of the side), twisting or biasing of the middle material.

  By inserting the elastic yarn, it becomes a fabric having a bulky three-dimensional structure, and is excellent in cushioning properties and heat retention by the air layer.

  Since the sheet-like fabric is appropriately cut and laminated and stitched, the knitted fabric itself has a three-dimensional structure including an air layer and becomes a fabric having air permeability and elasticity.

  Since a multifilament is used, a thin, light and softer fabric can be obtained without giving the wearer a feeling of weight.

  It is easy to form an air layer, thereby improving heat retention and air permeability, and optimizing the space environment between the intermediate material and the human body. That is, there is little stuffiness.

  It is easy to deform along with the human body, that is, it has excellent fit. In addition, it is easy to perform processing such as laminating stitching or point bonding with a resin or the like, and it is easy to impart form stability by heat setting.

  Since it is knitted as a sheet-like fabric, the final thickness of the intermediate material can be freely changed by laminating to a desired thickness. Moreover, when the quilting process is performed together with the side ground after being stored in the side ground, twisting of the intermediate material is not caused.

It is a photograph which shows the state which extended | stretched the warp knitted fabric for intermediate materials which concerns on this invention. It is a photograph showing the natural state. It is a plane photograph which shows the state which laminated | stacked the warp knitted fabric for intermediate materials which concerns on this invention in 4 layers. This is a front photo.

  The warp knitted fabric for intermediate materials according to the present invention is knitted by a warp knitting machine with an insertion function using only multifilament yarns of chemical fibers.

  The base fabric uses only multifilament chemical fibers and knits the base fabric in a mesh shape with coarse stitches such as Tenby knitting and marquisette knitting. Specifically, the filament yarn is preferably made of synthetic fiber such as viscose rayon, cupra rayon, acetate fiber, polyamide fiber, polyester fiber, polytrimethylene terephthalate fiber, acrylic fiber, polypropylene fiber, vinyl chloride fiber, etc. .

  The thickness of the yarn is preferably in the range of 15 denier to 300 denier from the viewpoint of sag resistance due to repeated washing.

  Furthermore, simultaneously with the knitting of the ground structure, an elastic yarn such as a rubber yarn is inserted separately from the ground to give strong elasticity to the entire base fabric.

  Moreover, you may give the resin process for providing a firmness and a firmness as needed, and may provide functional processes, such as a tick prevention by a well-known method, antibacterial, deodorizing, and a moisture absorption process.

  Since the warp knitted fabric of the present application is used as an intermediate material for bedding or the like and a batting material for clothing, the knitting density may be coarse. Specifically, a course of 5 to 20 eyes per 1 cm is suitable.

  A rubber yarn is appropriately introduced into the ground structure knitted with a coarse density to impart strong stretchability in the lateral direction of the entire base fabric. The number of inserted rubber threads and the interval can be easily changed depending on the intended use of the finished product.

  FIG. 1 is a photograph showing a state in which a part of the warp knitted fabric for intermediate material according to the present invention is cut and stretched and attached to a piece of paper (A4). It can be seen that the sheet is knitted so thin that the mount is transparent. FIG. 2 is a photograph showing a state where a part is released from the extended state. Since the elastic yarns are inserted and knitted at intervals of 120 mm, the state contracted to about half the width is the natural state of the warp knitted fabric of the present application. The degree of contraction can be appropriately changed according to the interval at which the elastic yarn is inserted and the number of elastic yarns inserted.

  In actual use, the warp knitted fabric of the present application is laminated and used. Since it is knitted into a sheet, it is easy to process it into an intermediate material of a desired size and thickness. FIG. 3 is a photograph showing the state of being laminated in four layers from the plane direction, and FIG. 4 is a photograph showing the front direction. The warp knitted fabric of the present application is a thin fabric that has firmness and stiffness, and is finished in a accordion-like contracted state, so that the volume is increased by laminating. On the other hand, when pressed, the flat state is obtained, so that it is easy to sew the fabric in an overlapped state, and it is also easy to sew the intermediate material laminated together with the side fabric after being stored in the side fabric such as a futon. For example, it is conceivable to sew the entire bedding with quilting. By doing so, the middle material is not twisted or displaced, and it is difficult for the laundry to lose its shape during repeated washing.

  When the drying speed of a single-size gauzeket with two layers of the intermediate material of the present application is inspected, the residual moisture content is already 51% after one minute of centrifugal dehydration, and after 90 minutes in an environment of 20 degrees and 65% humidity. The residual moisture content was in the 8% range. Since it is excellent in quick-drying, it is suitable for use in customers who want to wash everyday or at hotels and hospitals.

  As described above, after knitting the base fabric, it is possible to knit an intermediate material suitable for the intended use by knitting natural fibers such as cotton and wool or other functional fibers. This is the same as changing the outer clothing and the bedding side according to the season such as bedding and clothing.

  Excellent heat retention and no unnecessary bulkiness, so it can be used for sleeping / living materials such as comforters, kotatsu comforters, laps, etc. Is possible.
