[0001]
[Field of the Invention]
In particular, the present invention relates to a roll net door net for synthetic resin fiber yarns and a net for synthetic resin fiber yarns formed by knitting synthetic resin fiber yarns.
[0002]
[Prior art]
Recently, nets for screen doors knitted using synthetic resin fiber threads instead of wire mesh nets (for the purpose of insect protection, shading, shielding, etc.) have been developed and pleated using plastic deformation of synthetic resin fiber threads. A type that can be folded or a type that can be rolled up has been developed.
[0003]
For example, as a screen door using conventional Russell knitting, as shown in FIG. 7, a net of two middle weft yarns 2 and one back weft yarn, a total of three warp yarns and 75 denier yarns. Although it was manufactured as a roll screen door, when it was used as a roll screen door, when winding it with the opening and closing of the roll screen door, the thickness of the knitting net increased because the yarn was thick, The winding diameter becomes large and becomes bulky at the time of laying, and there is a disadvantage that a large space is required.
At the same time, even if 75 denier yarn is used, it is knitted, so there is also a problem that the looseness of the knitted structure is attached and it is difficult to stabilize the form in terms of strength.
[0004]
[Problems to be solved by the invention]
As a means for solving such a problem, first, in order to reduce the diameter when rolled, for example, it is conceivable to reduce the yarn to be used to 50 denier. However, the net has problems in terms of tensile strength, tearing, and elongation. That is, as a result, when the screen door is opened, it is difficult to maintain the shape of the net (flatness, etc.) and a state of bending or slackness appears.
[0005]
In the present invention, a roll screen door net formed by knitting synthetic resin fiber yarns is made thin so as to have a sufficient shape retaining property (flatness, etc.) while being able to reduce the winding diameter. The purpose is to allow the net to be heat-processed with good shape retention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the synthetic resin fiber yarn roll screen door net according to the present invention uses a core-sheath synthetic resin fiber yarn having a low melting point resin coated on its peripheral surface as a warp yarn. This is a net for roll screen doors of synthetic resin fiber yarns in which the same quality yarn or ordinary synthetic resin fiber yarns are knitted into a net shape by raschel knitting, and the intersections of the raschel knitting are joined by heat welding ,
At least one of the front warp, middle weft, and back weft is 50 denier or less in thickness,
Three middle weft yarns are knitted with three jumps from the right to the left with respect to the warp yarns at a predetermined interval at the front, and two back weft yarns.
Each of the warp yarns at a predetermined interval, which is the front, is knitted with two jumps from left to right. Between the two warp yarns, the three weft yarns of the middle and the two weft yarns of the back are mutually connected. It is configured to intersect.
[0007]
Further, in order to achieve the above object, the synthetic resin fiber yarn roll screen net according to the present invention uses a core-sheath synthetic resin fiber yarn having a low melting point resin coated on the peripheral surface as a warp yarn. This is a roll screen door net of synthetic resin fiber yarns, in which the same quality as warp yarn or normal synthetic resin fiber yarn is knitted into a net shape by raschel knitting, and the intersection of the raschel knitting is joined by heat welding There,
