Description

[Detailed explanation of the invention] This invention relates to a warp knitted fabric used as a sheet for light shielding, heat protection, wind protection, snow protection, etc., and specifically prevents strings woven along the wales from coming off in the wale direction. Regarding warp knitted fabrics.

Recently, warp knitted fabrics have been used as light-shielding sheets for agricultural crops.

To install this warp knitted fabric, the warp knitted fabric is fixed to the pillars at predetermined intervals using rod-shaped attachment fittings with hook-shaped ends.

In this case, the hook part of the mounting bracket is hooked onto the warp knitted fabric to secure it in place, so in order to prevent tearing at that point, conventionally thick strings were woven in the warp direction of the warp knitted fabric to create a string-like structure. The hook part was attached to the braided part.

However, in the above case, the strings are simply woven in a straight line between the wales of the warp knitted fabric, or are simply intertwined along the wales while passing through the loops of the wales, so wind pressure etc. When a large force is applied to the warp knitted fabric due to The problem was that it protruded in a dogleg shape, making it insufficiently fixed to the support.

This invention was devised to eliminate such drawbacks, and examples thereof will be described below with reference to the drawings.

W is a chain-knit wale made of monofilament yarn made of synthetic resin, which is arranged vertically and vertically at appropriate intervals.

2 is a thread connecting the wales W while reciprocating in a zigzag pattern; for example, a flat yarn made of synthetic resin is used.

3 is a string that is much thicker than threads 1 and 2, and has a wale W.
While passing through every other loop L from the left to the right and from the right to the left in a □ pattern, the string is entangled along the wale W, and the string is attached at predetermined intervals in the warp direction. 3 reciprocates between the wale W two wales apart on the upper left (on the drawing), and in the wale W at the turning point and the wale W in the middle, the outgoing part 3a and the incoming part 3b of the string 3 are connected to the respective wales W, It passes through successive loops L and L of W.

(Since string 3 is considerably thicker than threads 1 and 2, the state after knitting will be as shown in Figure 1).

The string 3 is, for example, a rope-like string formed by twisting a large number of monofilament yarns of synthetic fibers.

Although the string 3 is woven into the end of the warp knitted fabric in the figure, the woven position is not limited to the above.

Furthermore, in the case of the figure, the spacing between the strings 3 is narrower in the areas where the strings 3 are woven compared to the areas where the strings 3 are not woven, but this is not limiting.

Further, in the case of the figure, the string 3 is made to reciprocate between wales that are two wales apart, but it may be made to reciprocate between wales that are one wale away.

Note that it is preferable to use a thicker thread for the wale W of the loop L through which the string 3 passes than the wale that does not pass through it.

The warp knitted fabric of this invention has the above structure, and has three strings.
pass through the loop L of the wale W alternately from left to right and from right to left and become entangled along the wale W, and at predetermined intervals in the warp direction, the string 3 It reciprocates between the wale W which is more than 1 wre away, and at the turning part of the wale W, the outgoing part 3a of the string 3
and the return path 3b is a continuous loop L of the wale W,
Since I made it pass through the L, the string 3 is the wale W.

At the point where the W is reciprocated, the outgoing part 3a and the incoming part 3b come close to each other and are knitted in a two-fold state, resulting in a structure in which the string 3 is difficult to come off in the wale direction.

Moreover, in the above case, since the string 3 is reciprocated at predetermined intervals in the warp direction, the portion between the wales where the string 3 reciprocates can be formed in a firm state.
This is very convenient when handling.

In addition to being used as a light-shielding sheet, the warp-knitted fabric of this invention can also be used as a sheet to lay underneath during sericulture,
It can also be used as aquaculture net.
