This invention relates to the technical field of pipelines, and specifically a stitched double layer composite hose and a manufacturing method thereof.

Description of Related Arts

For the stitched double layer composite hose which is presently produced at home and abroad, when producing its fabric pipe layer, the traditional weaving method is adopted to produce single-layer plain or twill hose textile, then make a double middle by latching a fabric pipe layer on the outside of another fabric pipe layer, with different calibers between inner and outer fabric pipe layers, and this double fabric pipe layer is stiff and compactness between inner and outer layers is poor. The composite hose produced using this fabric pipe layer has weak peel-strength, rough surface, weak resistance to high pressure, strong resistance to water-flow, poor wear resistance, and easy to slip, not satisfying market needs.

colloid compositing, which comprises steps of: co-extruding coating rubber compound/thermoplastic elastomer on inner and outer surfaces of the fabric pipe layer once, or lining the rubber compound/thermoplastic elastomer on the inner surface and color painting on the outer surface.

As a preferred embodiment, a weaving structure of the fabric pipe layer is a double twill structure or double plain structure, and the total amount of the warps in the fabric pipe layer is determined in following manners, wherein:

when the weaving structure is in double twill stitching, the weaving structure is weaved using n complete cycle units, the amount of the warps in each complete cycle unit is 6, and the total amount of the warps in the fabric pipe layer is 6n+4;

when the weaving structure is in double plain stitching, the weaving structure is weaved using n complete cycle units, the amount of the warps in each complete cycle unit is 4, and the total amount of the warps in the fabric pipe layer is 4n+2.

As a preferred embodiment, the complete cycle unit applies the following weaving method comprising steps of: driving wefts by synchronous circling motions of set amount of shuttles on a weaving machine, making the wefts shuttling through layered warps to weave, cooperating with set amount of noseplates in a same weaving cycle for leasing, making shuttle lead wefts through the layered warps to connect inner and outer textiles, thus completing the weaving of the fabric pipe layer.

As a preferred embodiment, there are three shuttles.

As a preferred embodiment, when the complete cycle unit is in double twill stitching, the weaving method is as follows: the noseplate cooperating with a first shuttle has the following three leasing movements successively: one up one down one up three down, two down one up one down one up one down, one up three down one up one down (↑↓↑↓↓↓, ↓↓↑↓↑↓, ↑↓↓↓↑↓) and the shuttle leads wefts through layered warps to carry out the outer layer weaving; the noseplate cooperating with a second shuttle has the following three leasing movements successively: three up one down one up one down, one up one down three up one down, one up one down one up one down two up (↑↑↑↓↑↓, ↑↓↑↑↑↓, ↑↓↑↓↑↑) and the shuttle leads wefts through layered warps to carry out the inner layer weaving; the noseplate cooperating with a third shuttle has the following three leasing movements successively: two up two down one up one down, one up one down two up two down, two down one up one down two up (↑↑↓↓↑↓, ↑↓↑↑↓↓, ↓↓↑↓↑↑), and the third shuttle leads wefts through layered warps to carry out the connection of inner and outer textiles, thereby achieving the weaving of double twill weft stitching the fabric pipe layer of the hose.

As a preferred embodiment, when the complete cycle unit is in double plain stitching, the weaving method is as follows: the specially made noseplate cooperating with the first shuttle has the following two leasing movements successively: one up three down, two up(down) one up one down (↑↓↓↓, ↓↓↑↓), and the shuttle leads wefts through layered warps to carry out the outer layer weaving; the noseplate cooperating with the second shuttle has the following two leasing movements successively: three up one down, one up one down two up (↑↑↑↓, ↑↓↑↑), and the shuttle leads wefts through layered warps to carry out the inner layer weaving; the noseplate cooperating with the third shuttle has the following two leasing movements successively: two up two down, two down two up (↑↑↓↓, ↓↓↑↑), and the third shuttle leads wefts through layered warps to carry out the connection of inner and outer textiles, thereby achieving the weaving of double plain weft stitching the fabric pipe layer of the hose.

As a preferred embodiment, the rubber compound/thermoplastic elastomer is made of TPU, and the color painting is made of water-based TPU.

For the high-strength fiber double composite studied and produced according to this patent, its fabric pipe layer is a whole hose textile combined by using special weaving machine weaving inner and outer layers and at the same time through weft stitching to make relative independent inner and outer layers be weaved, making the textile flat and soft. This composite hose has greatly improved the resistance to pressure, finally solves the problem of large caliber composite hose's low resistance to pressure, with weak resistance to water-flow. The wear resistance of finished product is greatly improved. When the surface protective layer is worn, there is an outer layer of double stitched fabric pipe layer protecting the inner layer without the exposure of the lining. Even if without coating any protective layer to the surface of double stitched fabric pipe layer, its high strength outer layer still protects the inner layer. As a result, this patent of invention of high strength fiber stitched double layer composite hose especially applies to long-range field transport of gas and liquid media, and has relatively broad application prospects.

The weaving theory of this invention is as follows: driving wefts by synchronous circling motions of set amount of shuttles on a weaving machine, making the wefts shuttling through the layered warps to weave, cooperating with set amount of noseplates in the same weaving cycle for leasing, making shuttle lead wefts through the layered warps to connect the inner and outer textiles, thus completing the weaving of the fabric pipe layer of the hose.

The main differences between this weaving method and double casing fabric pipe layer lie in the following:

1. The amount of warps in a complete cycle unit is twice of that of a single-layer hose, and the amount of wefts in a complete cycle unit is three times of that of a single-layer hose;

2. If the wove stitched wefts are dismantled, there are still two complete and relatively independent inner and outer textile layers;

3. The amount increase of wefts can greatly improve pressure-resistance and wear resistance of the fabric pipe layer;

4. The stitched double fabric pipe layer is soft, with low coefficient of elongation and expansion, and less degree of torsion.

Beneficial effects of this invention are as follows:

1. The wove fabric pipe layer overcomes the problem of stitched double layer composite hose in traditional double casing fabric pipe layer;

2. The increase in the amount of wefts can greatly improve pressure-resistance and wear resistance of the fabric pipe layer;

3. It has such advantages as long service life, high flexibility, less interweaving points, less loss of yarn strength and less degree of torsion;

4. The fabric pipe layer with special coating equipment and special coating process can be directly produced into a stitched double layer composite hose satisfying market needs with large caliber, high dielectric strength and higher flexibility. The production process is simple, featured with extremely high utility value and worthy of promotion for production.
