Abstract

The utility model discloses a cord fabric with high intensity. The cord fabric with high intensity I knitted from warp yarns and weft yarns in an interlaced manner, wherein the warp yarns are two-strand yarns made of chinlon yarns and metal wires; the density of the warp yarns is greater than that of the weft yarns; the yarn diameter of each warp yarn is greater than that of each weft yarn. The warp yarns bear a load while the weft yarns are used for fixing the positions of the warp yarns, so that a steady structure is obtained; the warp yarns with relatively great intensity as well as yarn diameter are the two-strand yarns, so that the pressure bearing intensity of the warp yarns is improved efficiently, and a tire is enabled to have good impact resistance and good fatigue resistance. The cord fabric with high intensity is steady in structure and high in pressure bearing intensity, enables the tire to have good impact resistance and good fatigue resistance, and is applicable to tires with relatively high requirements on performances.

Description

High-strength cord fabric

Technical field

The utility model relates to a kind of cord fabric, relates in particular to a kind of high-strength cord fabric.

Background technology

Cord fabric is to make warp with powerful strand, with in, the ramuscule single thread makes latitude.Cord fabric is as the skeleton of the rubber such as tire, makes can the bearing immense pressure of tire, impact load and sharp pounding.But the line strength of existing cord fabric is low, in the situation that be subject to intense impact, easily damage, and the manufacture tire body need to be than the multilayer cord fabric, the frictional heating produced due to motion in use is high, heat radiation is slow, tire is easily deformed, had a strong impact on the quality of tire, the bearing strength of cord fabric becomes one of principal element of restriction tyre performance.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of Stability Analysis of Structures, and bearing strength is high, makes that tire is shock-resistant, fatigue performance good, is applicable to the high-strength cord fabric of the tire higher to performance requirement.

For solving the problems of the technologies described above, the technical solution of the utility model is: high-strength cord fabric, by warp thread and weft yarn weaving, formed, and described warp thread is the bifilar yarn that polyamide fibre yarn and wire are made; The density of described warp thread is greater than the density of described weft yarn, and the yarn footpath of described warp thread is greater than the yarn footpath of described weft yarn.

As preferred technical scheme, the polyamide fibre yarn in described bifilar yarn is wrapped on described wire, and the yarn footpath of described polyamide fibre yarn is greater than described diameter wiry.

As to improvement of the technical scheme, described weft yarn is acrylics filament or terylene thread.

As to further improvement in the technical proposal, described weft yarn is made for the nylon fibre and the metal fibre that mutually are intertwined.

As the further improvement to technique scheme, described warp thread and described weft yarn are the plain weave that weaving forms one on the other.

As to especially further the improving of technique scheme, described warp thread and described weft yarn are the plain weave that on two, twice weavings form.

Owing to having adopted technique scheme, high-strength cord fabric, formed by warp thread and weft yarn weaving, and described warp thread is the bifilar yarn that polyamide fibre yarn and wire are made; The density of described warp thread is greater than the density of described weft yarn, and the yarn footpath of described warp thread is greater than the yarn footpath of described weft yarn.Described warp thread bears load, and described weft yarn is used for fixing the position of described warp thread, Stability Analysis of Structures, and the density of described warp thread is large, the yarn footpath is large and be bifilar yarn, has effectively improved the bearing strength of described warp thread, makes that tire is shock-resistant, fatigue performance good.The utility model Stability Analysis of Structures, bearing strength is high, makes that tire is shock-resistant, fatigue performance good, is applicable to the tire higher to performance requirement.

The specific embodiment

Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation, some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that do not depart from spirit and scope of the present utility model, can to described embodiment, be revised by various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than for limiting the protection domain of claim.

Embodiment mono-: as shown in Figure 1, Figure 2 and Figure 3, high-strength cord fabric, formed by warp thread 1 and weft yarn 2 weavings, the bifilar yarn that described warp thread 1 is made for polyamide fibre yarn 5 and wire 6; The density of described warp thread 1 is greater than the density of described weft yarn 2, and the yarn footpath of described warp thread 1 is greater than the yarn footpath of described weft yarn 2.Described warp thread 1 and described weft yarn 2 are the plain weave that weaving forms one on the other.The spacing of described warp thread 1 evenly is set to 5mm-25mm, and it is best selecting 13mm; The spacing of described weft yarn 2 evenly is set to 10mm-30mm, and selecting 20mm be the best, makes the density of described warp thread 1 be greater than the density of described weft yarn 22.The yarn footpath of described warp thread 1 is set to 1mm-2mm, and the yarn footpath of described weft yarn 2 is set to 0.5mm-1mm.Described warp thread 1 bears load, described weft yarn 2 is used for fixing the position of described warp thread 1, Stability Analysis of Structures, and the density of described warp thread 1 is large, the yarn footpath is large and be bifilar yarn, effectively improved the bearing strength of described warp thread 1, made that tire is shock-resistant, fatigue performance good.The present embodiment Stability Analysis of Structures, bearing strength is high, makes that tire is shock-resistant, fatigue performance good, is applicable to the tire higher to performance requirement.

As shown in Figure 4, the polyamide fibre yarn 5 in described bifilar yarn is wrapped on described wire 6, and the yarn footpath of described polyamide fibre yarn 5 is greater than the diameter of described wire 6.Can effectively improve intensity and the toughness of described warp thread 1.

Described weft yarn 2 can be acrylics filament or terylene thread.Can fix the position of described warp thread 1, Stability Analysis of Structures.

As shown in Figure 5, described weft yarn 2 also can be made for the nylon fibre 3 and the metal fibre 4 that mutually are intertwined.Wherein said metal fibre 4 accounts for 20%, and described nylon fibre 3 accounts for 80%, can effectively improve the intensity of described weft yarn 2.

Embodiment bis-: as shown in Fig. 6, Fig. 7 and Fig. 8, embodiment bis-is with the difference of embodiment mono-, and described warp thread 1 and described weft yarn 2 are the plain weave that on two, twice weavings form.This Stability Analysis of Structures, bearing strength is high, makes that tire is shock-resistant, fatigue performance good, is applicable to the tire higher to performance requirement.

Described warp thread 1 and described weft yarn 2 can be also the twill-weave that on two, once weaving forms.
