Abstract

The utility model discloses a tri-axial tricot fabric, which consists of a first yarn layer, a second yarn layer, a third yarn layer and a binder yarn, wherein the first and the second yarn layers areformed by arranging yarns in the positive and the negative 45-degree directions, the third yarn layer is formed by arranging the yarns in the zero-degree direction, and the binder yarn binds and knits the first, the second and the third yarn layers into a whole body and is arranged in the zero-degree direction; the number of the yarns both in the positive and the negative 45-degrees is 300 tex, the number of warp threads in the zero-degree direction is 1200 tex, the number of the binder yarns is 8.3 tex, the density of the yarns both in the positive and the negative 45-degree direction is 433yarns per meter, the density of the warp threads and the binder yarns in the zero-degree direction is respectively 413 yarns per meter and 394 yarns per meter, and the density of coils on the binderyarns is 350 per meter. Both the warp and the weft threads are of a glass-fiber yarn, and the binder yarn is of a terylene yarn. The density of yarns in different directions is correctly controlled, and the weight of the fabric per square meters reaches the standard gram weight, so the application requirement is satisfied.

Description

Three axial tricots

Technical field

The utility model relates to a kind of tricot, 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, 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, and number number of bundled yarn is 8.3tex; 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 870 ± 3%g/m ², and when producing, owing to control inaccurately to the density of all directions yarn, fabric does not reach specified standard grammes per square metre, thus make the blade of making can't 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 precise control to all directions yarn, thereby makes fabric reach three axial tricots of standard grammes per square metre.

For solving the problems of the technologies described above, a kind of three axial tricots that the utility model adopted, 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 the warp thread of described zero degree direction is 1200tex, number number of described bundled yarn is 8.3tex, just described, the density of the weft yarn of negative 45 degree directions is 433 pieces/meter, the density of the warp thread of described zero degree direction is 413 pieces/meter, the density of the bundled yarn of described zero degree direction is 394 pieces/meter, and the density of the coil on described bundled yarn is 350/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 433 pieces/meter, the density of the warp thread of described zero degree direction adopts 413 pieces/meter, and the density of the bundled yarn of described zero degree direction is 394 pieces/meter, and the density of the coil on described bundled yarn is 350/meter; The fabric of producing like this, the grammes per square metre of positive and negative 45 degree direction weft yarns is 184g/m ², the grammes per square metre of zero degree direction warp thread is 496g/m ², the bundled yarn grammes per square metre is 8g/m ², thereby the fabric of this structure has reached standard grammes per square metre 870 ± 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 weft layers, and the intermediate layer is second weft layers, and top layer is the 3rd weft layers.Adopt such structure, make the structure of fabric more reliable, in use reach optimum efficiency.

Description of drawings
