Abstract

PROBLEM TO BE SOLVED: To provide a knitted fabric that is in no need of forming holes by breaking the fibrous texture and is in no anxiety of reduction in the texture strength. SOLUTION: In a knitted fabric that comprises, in the cross direction, the main body of the knitted fabric R2, the rudder part R1 and the selvedge part R3, the threads for button hole fabric are allowed to swing over the rudder part R1 and the parts adjacent to both sides of the R1, namely the main knitted part R2 and the selvedge part R3 in several courses and the threads are knitted. Further, in the hole parts H formed at a suitable interval in the longitudinal direction of the rudder R1, the fabric threads on the swung hole are knitted only at the selvedge part R3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven or knitted sheet or a sheet made of synthetic resin or the like, which is sewn or welded to an edge of the sheet to connect the sheets to each other or to connect the sheets to each other. For example, the present invention relates to a knitted material such as a narrow knitted fabric or a knitted sheet to be attached to a fixed material such as a pillar, a pile, a standing tree, a building, a scaffold, and the like.

[0002]

2. Description of the Related Art In general, seats are widely used in tents, construction curing and the like.
It may be used by attaching to fixed objects such as pillars, piles, standing trees, buildings, and scaffolds.

Heretofore, in such a sheet for connection, a narrow fabric has been attached to an edge portion thereof, or the fabric sheet itself has been used, and the edge portion of the narrow fabric or the fabric sheet has been used. A hole for connection is formed in the portion, and sheets are connected to each other or a sheet is fixed to the fixing material through a binding string through the hole.

[0004]

However, the above-mentioned conventional narrow woven fabric and woven fabric sheet have the following problems. 1) To form a hole in the edge part for passing the connecting material,
Attaching an annular metal fitting to the woven fabric or fusing the woven fabric required special fittings and a fusing device, which not only increased the manufacturing cost, but also weakened the fabric structure around the hole by breaking, As a result, there was a problem that durability was lacking. 2) In particular, in the case of a narrow-width woven fabric, there is a case where the woven fabric is attached to the edge portion of another woven fabric sheet or a synthetic resin sheet by welding. If a gap is provided, there is a problem that the woven structure becomes unstable and the strength is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to eliminate the need to break a tissue to form a hole and to form the above gap for welding. To provide a knitted fabric that does not have a risk of lowering the tissue strength.

[0006]

According to the present invention, there is provided a knitted fabric having a knitted body portion, a ladder portion, and an ear portion in a width direction.
While knitting by swinging the perforated yarn over several courses of the knitted body portion and the ear portion adjacent to the ladder portion and both sides thereof, at a hole portion formed at an appropriate interval in the longitudinal direction of the ladder portion, The hole ground yarn is knitted only on the ear portion. It is also characterized in that warp insertion yarns for reinforcement are inserted into several courses of the knitted fabric main body portion and the ear portions adjacent to both sides of the ladder portion.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. In FIG. 1, R is a narrow-width knitted fabric having a desired width, and a ladder portion R1 having a predetermined width is integrally formed near one side edge thereof. In the present specification, the knitted portions other than the ladder portion R1 are referred to as a knitted body main portion R2 and ear portions R3. Holes H are formed in the ladder portion R1 at appropriate intervals in the longitudinal direction. Further, the knitted fabric in the present invention is not limited to the narrow width, and the knitted fabric main body portion R2 may be a wide sheet-shaped knitted fabric.

FIG. 2 shows the design paper showing the knitting structure of the knitted material R and the threading state of each guide bar. The black dots in the figure show the positions of the needle heads in each course. FIG. 3 is an organizational diagram focusing on one of the yarns knitting the knitting arrangement of FIG.

In FIGS. 2 and 3, L1 is a chain knitting yarn knitted by the first guide bar, and is a chain-shaped open loop in which the guide bar overlaps the same needle for each course. Form a chain stitch. The chain knitting yarn L1 is fully set on the first guide bar over the knitted body main portion R2 and the ear portion R3, and knits a chain stitch base fabric.

L2 is a back insertion yarn in the ear R3, which is inserted between the needle loop and the sinker loop in the same course of the chain stitch knitted by the chain knitting yarn L1. Idol swings across and is woven. L3 is a back insertion yarn in the knitted fabric main body portion R2, which is inserted between a needle loop and a sinker loop in the same course of a chain stitch knitted by the chain knitted yarn L1, and has a width of the knitted fabric main body portion R2. Is idle-swinged so as to cross all the needles in the range.

L4 is the knitted main body portion R2 and the ear portion R
The front insertion yarn 3 is inserted into the chain knitting yarn L1 from the opposite direction to the back insertion yarns L2 and L3, and is knitted by performing an idle swing across three needles.
L5 is also a front insertion yarn similar to the front insertion yarn L4, and includes a knitted fabric main body portion R2 and ear portions R3 on both sides of the ladder portion R1.
Idle swing and weave to cross two needles in

L6 is a hole yarn for forming a hole H in the ladder portion R1. Except for the hole H, four courses of the knitted body main portion R2 adjacent to the ladder portion R1 and ears R3 are formed. It is knitted by idle swing so as to cross over 18 courses including 6 courses, and in the hole H part,
The knitting is performed by performing an idle swing so as to cross only the six courses of the ear R3. Further, the hole ground yarn L6 has a hole H
The swing is repeated 12 times except for the portion, and two swings are performed in the hole H portion.

L7 is a warp insertion yarn for reinforcing the tissue on both sides of the hole H, and is inserted into each of three courses of the knitted main body portion R2 and the ear portion R3 adjacent to the ladder portion R1. L8 is a warp insertion thread for reinforcing the ear R3, which is inserted into one course of the edge of the ear R3. An ester thick cord is used as the warp insertion yarn L8.

The knitted fabric of the present invention is not limited to the knitting structure using the above-described knitted base fabric or inserted yarn. At least a ladder portion R1 is knitted, and holes H having an appropriate size are formed in this portion at appropriate intervals. Any knitting structure that can be knitted may be used. FIG. 4 shows a knitted fabric of another embodiment in which holes H are arranged at equal intervals.

[0015]

1) Since the holes are formed by knitting, there is no need to form holes by cutting or fusing the yarn, and there is no danger that the strength of the structure will be reduced. 2) The knitting structure of the hole can be effectively reinforced by inserting reinforcing warp yarns on both sides of the ladder portion forming the hole.
