Description

A kind of through compiling triaxial fabric

Technical field

The utility model relates to a kind of tricot, particularly relate to a kind of zero degree and positive and negative 45 degree directions through compiling triaxial fabric.

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 through compiling three axial glass fabrics, 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, become one and the bundled yarn formation that be positioned at the zero degree direction of the second and the 3rd layer binding braiding, just described, number number average of the weft yarn of negative 45 degree directions is 300tex, number number of the warp thread of zero degree direction is 1200tex or is 2400tex that number number of bundled yarn is 8.3tex; As the wind power generation blade reinforcing material time, corresponding to comparatively desirable a kind of through compiling three axial glass fabrics of wind power plant, its grammes per square metre is 1250 ± 3%g/m ², and to require the warp thread grammes per square metre of zero degree direction be 637g/m ², the weft yarn grammes per square metre of positive and negative 45 degree directions is respectively 300g/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 specified standard grammes per square metre, thereby make the blade of making to satisfy the wind power plant necessary requirement, even in use generating equipment is caused damage.

The utility model content

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, thus make fabric reach the standard grammes per square metre through compiling triaxial fabric.

For solving the problems of the technologies described above, what the utility model adopted is a kind of through compiling triaxial fabric, 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, become one and the bundled yarn formation that be positioned at the zero degree direction of the second and the 3rd layer binding braiding, just described, number number average of the weft yarn of negative 45 degree directions is 300tex, number number of described bundled yarn is 8.3tex, two kinds of warp thread that the warp thread of described zero degree direction is respectively 1200tex and 2400tex by number number replace laying-in and constitute, and are just described, the density of the weft yarn of negative 45 degree directions is 709 pieces/meter; The density of the warp thread of described zero degree direction is 354 pieces/meter, and the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the loop density on described bundled yarn is 330/meter.

The weft yarn of the weft yarn of described positive 45 degree directions, negative 45 degree directions and the warp thread of zero degree direction are glass fiber yarn, and described bundled yarn is the terylene yarn.

After adopting such structure, because the density at positive and negative 45 degree direction weft yarns all adopts 709 pieces/meter, the density of the warp thread of described zero degree direction adopts 354 pieces/meter, two kinds of warp thread that the warp thread of this zero degree direction is respectively 1200tex and 2400tex by number number replace laying-in and constitute, the warp thread of 1200tex is 177 in every meter, the warp thread of 2400tex is 177, and the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the loop density on described 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 300g/m ², the grammes per square metre of zero degree direction warp thread is 637g/m ², the bundled yarn grammes per square metre is 8.2g/m ², thereby the fabric of this structure has reached standard grammes per square metre 1250 ± 3%g/m ²Thereby, guaranteed the quality of products such as wind power generation blade to have satisfied the instructions for use of product.

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.Adopt such structure, make the structure of fabric more reliable, in use reach optimum efficiency.
