Description

A kind of tricot

Technical field

The utility model relates to a kind of tricot, particularly relates to a kind of at three of zero degree and the positive and negative 45 degree tricot on axially.

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 that 300tex or number number average are 600tex, number number of the warp thread of zero degree direction is 600tex, 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 798 ± 3%g/m ²And when producing,, make the fabric that knits out not reach specified standard grammes per square metre owing to control inaccurately through the density and the yarn variety of weft yarn to all directions, therefore 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 and yarn variety to all directions yarn and is provided with accurately, thereby makes the fabric that knits out reach the tricot of standard grammes per square metre.

For solving the problems of the technologies described above, a kind of tricot 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, number number of the warp thread of described zero degree direction is 600tex, number number of described bundled yarn is 8.3tex, two kinds of weft yarns that the weft yarn of described positive 45 degree directions is respectively 300tex and 600tex by number number are alternately spread latitude and are constituted, two kinds of weft yarns that the weft yarn of described negative 45 degree directions is respectively 300tex and 600tex by number number are alternately spread latitude and are constituted, just described, the density of the weft yarn of negative 45 degree directions is 472 pieces/meter, the density of the warp thread of described zero degree direction is 315 pieces/meter, the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the loop density 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 472 pieces/meter, two kinds of weft yarns that the weft yarn of wherein positive 45 degree directions is respectively 300tex and 600tex by number number are alternately spread latitude and are constituted, two kinds of weft yarns that the weft yarn of negative 45 degree directions is respectively 300tex and 600tex by number number are alternately spread latitude and are constituted, the density of the warp thread of described zero degree direction adopts 315 pieces/meter, the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the loop density on described bundled yarn is 350/meter; Therefore, the fabric of producing like this, the grammes per square metre of positive and negative 45 degree direction weft yarns is 300.3g/m ², the grammes per square metre of zero degree direction warp thread is 189g/m ², the bundled yarn grammes per square metre is 7.8g/m ², thereby the fabric of this structure has reached standard grammes per square metre 798 ± 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.
