Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mesh bag used in an electric washing machine to contain and protect laundry.

[Conventional technology]

FIGS. 6 and 7 show conventional examples of laundry net bags. Using a coarse mesh wide net fabric made of synthetic fiber filament with a smooth surface and treated with water-resistant resin, this is cut into a vertically long rectangular net fabric, and the upper and lower ends are folded at the upper fold line 31 and the lower fold. Fold each end from the line of sight 32 and butt the free edges at both ends to form a laundry entrance/exit 33.The two overlapping left and right side edges are covered with tape cloth 34 and joined with sewing machine sutures 35 to form a bag body.The laundry entrance/exit 33 is equipped with a slide fastener. 36 is sewn to allow it to be opened and closed. This net bag is manufactured by turning it inside out after sewing (see the chain line in Figure 7) with the tape cloth inside.

[Problem that the invention attempts to solve]

However, in this conventional laundry mesh bag,
Because it is in the vortex of an electric washing machine, being agitated and in contact with the rotating blades for a long time, the sewing thread breaks, the sewing machine suture line 35 comes undone, and it often tears from there, resulting in poor durability and the loose side edges. There were problems such as the need for tape cloth and sewing work using a sewing machine for joining, making it time-consuming to manufacture.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention consists of a cylinder-shaped net fabric in which a double knitted fabric knitted with a knitting machine such as a ratssel knitting machine is connected on both warp side edges. In this method, the double knitted fabrics are joined at required intervals to form a bag body, and one of the double knitted fabrics has a vertical striped fraying part that creates a laundry entrance/exit. A bag base material is created by providing a stopper knitted part and cutting off the transversely striped fray-preventing knitted part;
The bag base material is made by cutting out the vertical striped anti-raveling part, attaching a slide fastener, and then turning the bag base material inside out.

[Effect]

According to this invention, the periphery of the bag is knitted in advance with a fray-preventing stitch using a knitting machine, making it unnecessary to sew the hemline using a sewing machine, and the fray-preventing stitch is formed in the stitches of the double-knitted fabric. The splints are tied together,
The cut edges do not fray and have great durability.

〔Example〕

1 to 5 show examples of this invention. The laundry net bag is a double knitted fabric in which an upper knitted fabric 1 and a lower knitted fabric 1 made of nylon filaments are connected at both warp side edges 3, knitted by a knitting machine such as a double ratcell knitting machine, and it is water resistant after knitting. It is made from a smooth tube-shaped knitted fabric (see Fig. 2) that has been treated with resin so that the stitches retain their shape and open inside.

This molded net fabric is made by continuously knitting a plurality of bag base materials A (see Fig. 3), and a transverse strip-like fray-preventing knitted part 4 with a width of about 35 mm crosses this partition part. At the same time, a warp-like fraying prevention knitted part 6 (see Fig. 5) with a width of about 35 mm that forms a laundry entrance/exit 5 (see Fig. 1) is continuous at a position biased to the right side of the upper knitted fabric 1 only. It is organized as follows.

At both warp side edges 3, each stitch of the upper knitted fabric 1 and the lower knitted fabric 2 is continuous.

The fray-prevention binding part 4 has a width of 10 mm in the center.
A separation band 7 of a relatively small width is provided continuously, and is divided into two fray-preventing knotted parts 4', 4'. As shown in FIG. 4, this fray-prevention binding knitted part 4 is knitted by finely knitting another splint thread 8 between the overlapping upper knitted fabric 1 and lower knitted fabric 2. Even if the center part of the separation band 7 is cut (see arrow direction C in FIG. 4), the knitting yarn will not come undone from the cut end.

The long shaped knitted fabric (see Figure 2) is separated at the center of the separation band 7 (see arrow direction C in Figure 2).
Then, a plurality of bag base materials A (see Fig. 3) are completed,
The bag is completely unraveled on all four sides.

The fray-preventing knitted part 6 has a narrow separation band 9 with a width of about 10 mm connected to the center thereof, and is divided into two fray-preventing knitted parts 6' and 6'. This anti-fray knitting part is formed by knitting the weft yarn 10 as a splicing yarn at a fine pitch, and the knitting yarn will not fray even if the central part of the separation band is cut. The laundry entrance/exit 5 can be opened and closed by sewing a slide fastener 11 to the cut edge.

The fray-prevention binding knitted portion 4 and the fray-preventing knitted portion 6 to be cut as described above are each provided with a separation band in the center of which no plint is present.
This makes cutting work accurate and easy when creating bag base materials.

The laundry net bag is made by using the bag base material A and cutting the center part of the separation band 9 of the anti-fray knitting part 6 (fifth
(see arrow direction C in the figure), a slide fastener 11 is attached to form a laundry entrance/exit 5, and the entire product is turned over and the protruding fray-preventing knotted part is placed inside.

In addition, the cylinder-shaped knitted fabric used in this invention can be easily knitted with plating threads by operating the patterning mechanism on a double lattice knitting machine to knit the fray-preventing binding part and the fray-preventing knitted part. Can be done.

〔effect〕

As mentioned above, the laundry net bag according to this invention is made of a tube-shaped knitted fabric knitted by a ratchet knitting machine or the like, and is machine-treated to prevent fraying in advance. Because of this, it is more durable than the conventional method, which is made by layering tape cloth and bordering it with machine stitching lines, and it does not tear at the fraying part even if it is agitated in an electric washing machine and comes into contact with the rotating blades for a long time. It has the advantage that it can be used for a long time without any problems, and that the sewing work after cutting can be greatly simplified.

[Scope of utility model registration request] The double knitted fabric knitted by a knitting machine such as a Ratssel knitting machine is made of a cylinder-shaped net fabric that is connected at both warp side edges, and this formed net fabric has transverse strip-like fray-preventing bonded knitted parts at required intervals. Here, the double knitted fabrics are joined together to form a bag body, and one of the double knitted fabrics is provided with a vertical streak-like fray-preventing knitted part that creates a laundry entrance/exit, and the horizontal strip-like fray-preventing binding knitting is provided. This net bag for laundry is made by cutting out the bag base material, cutting out the vertical striped anti-fray part, attaching a slide fastener, and turning the bag base material inside out.
