The thread materials 2.4 of the first diagonally inserted thread portion 3 and the second diagonally inserted thread portion 5 are tied together with a loop thread 6 and fixed.

The intersecting state of the thread material 2 of the first diagonally inserted thread portion 3 and the thread material 4 of the second diagonally inserted thread portion 5 is not necessarily limited to the perpendicular shape, but as shown in the drawings. 2 and the thread material 4 may be made to intersect so as to form a diamond shape.

Thread material 2 and thread material 4 are monofilament, multifilament, and spun yarn made of synthetic fibers.

Any type of thread from elastic thread, processed thread, metallic thread, etc.
Alternatively, a combination of two or more types of threads can be used.

On the other hand, since the loop thread 6 described above is for fixing the thread material 2 of the first diagonally inserted thread portion 3 and the thread material 4 of the second diagonally inserted thread portion 5, the above-mentioned thread material 2 and thread material Although it is possible to use a thread material thinner than thread material 2.4, the material is the thread material 2. Like the yarn material 4, it is desirable to use any one of synthetic fibers such as monofilament, multifilament, spun yarn, elastic yarn, textured yarn, metallic yarn, etc., or a combination of two or more yarns twisted together. Then, one or two of the loop threads 6 are tied around the thread material 2 or the thread material 4 in a loop shape and tied together, so both thread materials 2.4 can be sufficiently fixed.

When the reinforcing core fthf described above is integrated with a natural rubber, synthetic rubber, or synthetic resin part, this product can be produced in the direction of the thread material 2 of the first diagonally inserted thread part 3 and the thread material of the second diagonally inserted thread part 5.

Something will happen. For example, in the fifth embodiment, the weft insertion yarn portion 12 is used instead of the warp insertion yarn portion 9, or the warp insertion yarn portion 9 and the weft insertion yarn portion 12 are overlapped to form the loop yarn 6 and the insertion yarn 15. It is also possible to fix each thread material while intertwining it in series.

Next, application examples of the synthetic resin product of the present invention will be explained.

Application example 1: Application as a tire coat.

■Thread material for the first diagonally inserted yarn portion and second diagonally inserted yarn portion Synthetic fiber filament Twisted yarn equivalent to 1000 denier ■Thread material for the weft inserted yarn portion Spun yarn equivalent to 1/1O ■Loop yarn Synthetic m-fiber filament 100 denier ■ Gauge 16N18/inch ■ Drive
16 to 18 coats/inch The reinforced interlining having the above configuration is immersed in a solution of resorcinol resin latex,
This coat and rubber are passed through a rotating roll at the same time, and the rubber is pressed onto one side of the reinforcing interlining to give a vulcanized finish.

Generally, tire cords are made by threading eight 7cm lengths of twisted yarn equivalent to 1000 denier in the warp direction through a loom while applying tension, then fixing this fabric with latex using a sudare weave fabric with weft threads woven into it every 1cm or so. It is cut into strips on the bias, and three or four of these strips are polymerized and incorporated into the rubber.

However, when the reinforcing interlining of the present invention is used, since it has the first diagonally inserted yarn portion and the second diagonally inserted yarn portion in the diagonal direction (bias direction), the work of bias cutting can be omitted. It is possible to make two briars in one machining process, greatly improving production costs and production efficiency.

In addition, if a coupler yarn is used as the first and second diagonally inserted yarns, it is possible to obtain a tire having twice or more strength compared to nylon or polyester yarns.
