Abstract

The utility model discloses a tri-axial warp knitted fabric which consists of a first yarn layer and a second yarn layer which are formed by a plurality of weft yarns arranged with one another along with the direction of plus/minus 45 degrees, a third yarn layer which is formed by a warp yarn arranged along with the direction of 0 degree, and a bound yarn which is integrally woven by the first yarn layer, the second yarn layer and the third yarn layer in a binding way along with the direction of 0 degree; the number of the weft yarn along with the direction of plus 45 degrees is 300tex, and the density is 472 yarns per meter; the number of the weft yarn along with the direction of 0 degree is 2400tex, and the density is 236 yarns per meter; the number of the weft yarn along with the direction of minus 45 degrees is 600tex, and the density is 236 yarns per meter; and the number of the bound yarn is 8.3tex, the density is 236 yarns per meter, and the stitch density on the bound yarn is 330 yarns per meter. The warp yarns and the weft yarns are glass fiber yarns, and the bound yarn is polyester yarn. The yarn density and the type of the fabric along with each direction are accurately set, and the weight of each square meter achieves the required gram weight, so that the use requirement is preferably met.

Description

A kind of have three axial tricots

Technical field

The utility model relates to a kind of tricot that is formed by the multiple-axial warp knitting machine braiding, particularly relates to a kind of three axial tricots in zero degree and positive and negative 45 degree directions.

Background technology

At present, as wind power generation blade, the tricot of reinforcing materials such as ships and light boats, especially a kind of widely used three axial glass fibre tricots, first layer that it is made of the weft yarn arrangement of positive 45 degree directions, second layer that the weft yarn arrangement of negative 45 degree directions constitutes, the warp thread of zero degree direction is arranged the 3rd layer that constitutes and with described first, the binding of the second and the 3rd layer weaves the bundled yarn formation that becomes one and be positioned at the zero degree direction, just described, number number average of the weft yarn of negative 45 degree directions is 300 tex, number number of the warp thread of zero degree direction is 2400 tex, and number number of bundled yarn is 8.3 tex; As the wind power generation blade reinforcing material time, corresponding to a kind of three comparatively desirable axial glass fibre tricots of wind power plant, its grammes per square metre is 1177 ± 3% g/m ², and to require the warp thread grammes per square metre of zero degree direction be 567 g/m ², the weft yarn grammes per square metre of positive and negative 45 degree directions is respectively 301g/m ²And when producing, owing to control inaccurately to all directions through the density and the yarn variety of weft yarn, fabric does not reach or over proof standard grammes per square metre, thereby make the blade of making to satisfy the wind power plant necessary requirement, even in use damage generating equipment.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of density and yarn variety to all directions yarn and is provided with accurately, thereby makes fabric weight reach 1177 ± 3% g/m ²Three axial tricots.

For solving the problems of the technologies described above, the utility model adopted a kind ofly has three axial tricots, first layer that constitutes of weft yarn arrangement by positive 45 degree directions, second layer that the weft yarn arrangement of negative 45 degree directions constitutes, the warp thread of zero degree direction is arranged the 3rd layer that constitutes and with described first, the binding of the second and the 3rd layer weaves the bundled yarn formation that becomes one and be positioned at the zero degree direction, number number of the weft yarn of described positive 45 degree directions is 300 tex, number number of the warp thread of described zero degree direction is 2400 tex, number number of described bundled yarn is 8.3 tex, number number of the weft yarn of described negative 45 degree directions is 600tex, the weft count of described positive 45 degree directions is 472 pieces/meter, and the weft count of described negative 45 degree directions is 236 pieces/meter; The warp count of described zero degree direction is 236 pieces/meter, and the bundled yarn density of described zero degree direction is 236 pieces/meter, and the loop density on described bundled yarn is 330/meter.

In the utility model, the weft yarn of described positive 45 degree directions, the weft yarn of negative 45 degree directions and the warp thread of zero degree direction are glass fiber yarn, and described bundled yarn is a Polyester Yarns.

After adopting such structure, because the latitude yarn number number of negative 45 degree directions is 600tex, the weft count of positive 45 degree directions is 472 pieces/meter, and the weft count of negative 45 degree directions is 236 pieces/meter; The warp count of zero degree direction is 236 pieces/meter, and the bundled yarn density of zero degree direction is 236 pieces/meter, and the loop density on bundled yarn is 330/meter.The fabric of producing like this, the grammes per square metre of positive and negative 45 degree direction weft yarns is 301g/m ², the grammes per square metre of zero degree direction warp thread is 567g/m ², the bundled yarn grammes per square metre is 8.2g/m ², thereby the fabric of this structure has reached grammes per square metre 1177 ± 3%g/m ²Thereby, satisfied the instructions for use of product, and guaranteed the quality of products such as wind power generation blade.

As a kind of preferred implementation of the present utility model, the bottom of fabric is first layer, and the intermediate layer is second layer, and top layer is the 3rd layer.After adopting such structure, the structure of fabric is more reliable, in use can reach optimum efficiency.
