A kind of three axial tricots
Technical field
The utility model relates to a kind of tricot, particularly relates to a kind of three axial tricots.
Background technology
Tricot as reinforcing materials such as wind power generation blade, ships and light boats, especially present widely used a kind of three axial glass fibre tricots, generally adopt positive and negative 45 degree and three cloth of zero degree, second layer that the weft yarn arrangement of its first layer that is made of the weft yarn arrangement of positive 45 degree directions, negative 45 degree directions constitute, the warp thread of zero degree direction arrange the 3rd layer that constitutes and will be described first, second and the binding of the 3rd layer weave the bundled yarn that becomes one and constitute; But as the wind power generation blade reinforcing material time, corresponding to the wind power plant of certain power, the grammes per square metre of the tricot that requires is 1245 ± 3%g/m
2And adopt positive and negative 45 degree and three cloth of zero degree, the instructions for use that does not then reach regulation is by three blades that cloth makes of this structure, can't satisfy this wind power plant necessary requirement, even in use this generating equipment be caused damage.
The utility model content
The technical problems to be solved in the utility model provides a kind of angle and density of spreading yarn and is provided with rationally, thereby makes fabric reach three axial tricots of regulation instructions for use.
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 60 degree directions, second layer that the weft yarn arrangement of 90 degree directions constitutes, the 3rd layer that the weft yarn arrangement of negative 60 degree directions constitute 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 60 degree directions is 300tex, number number of the weft yarn of described 90 degree directions is 1200tex, number number of the bundled yarn of described zero degree direction is 8.3tex, just described, the density of the weft yarn of negative 60 degree directions is 866 pieces/meter, the density of the weft yarn of described 90 degree directions is 531 pieces/meter, the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the density of the coil on bundled yarn is 380/meter.
The weft yarn of the weft yarn of the weft yarn of described positive 60 degree directions, negative 60 degree directions and 90 degree directions is glass fiber yarn, and described bundled yarn is the terylene yarn.
Such fabric construction, owing to adopted the weft yarn of positive and negative 60 degree directions and the weft yarn of 90 degree directions, and the density of positive and negative 60 degree direction weft yarns all adopts 866 pieces/meter, the density of the weft yarn of 90 degree directions adopts 531 pieces/meter, the density of the bundled yarn of zero degree direction adopts 236 pieces/meter, and the density of the coil on bundled yarn is 380/meter; Thereby the fabric of this structure, the grammes per square metre of positive and negative 60 degree direction weft yarns is 300g/m
2, the grammes per square metre of 90 degree direction weft yarns is 637.8g/m
2, the bundled yarn grammes per square metre is 7.4g/m
2, thereby the fabric of this structure reached the instructions for use of specific wind power plant defined, promptly the grammes per square metre of fabric is 1245 ± 3%g/m
2Thereby, guaranteed safe, the normal use of wind power plant.
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.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model three axial tricots.
Fig. 2 is a kind of structural representation of bundled yarn in the utility model three axial tricots.
The specific embodiment
Referring to Fig. 1, the axial tricot in shown in 2 a kind of three, its weft yarn 1 by positive 60 degree directions is arranged first layer that constitutes, the weft yarn 2 of 90 degree directions is arranged second layer that constitutes, the weft yarns 3 of negative 60 degree directions are arranged the 3rd layer that constitutes and with described first, become one and bundled yarn 4 formations that be positioned at the zero degree direction of the second and the 3rd layer binding braiding, just described, the weft yarn 1 of negative 60 degree directions, 3 number number average is 300tex, number number of the weft yarn 2 of described 90 degree directions is 1200tex, number number of the bundled yarn 4 of described zero degree direction is 8.3tex, just described, the weft yarn 1 of negative 60 degree directions, 3 density is 866 pieces/meter, the density of the weft yarn 2 of described 90 degree directions is 531 pieces/meter, the density of the bundled yarn 4 of described zero degree direction is 236 pieces/meter, as shown in Figure 2, the density of coil 4-1 on described bundled yarn 4 is 380/meter, promptly on the length direction of bundled yarn 4, the quantity of coil 4-1 is 380 every meter.
The weft yarn 2 of the weft yarn 3 of the weft yarn 1 of described positive 60 degree directions, negative 60 degree directions and 90 degree directions all adopts glass fibre alkali-free rove, and described bundled yarn 4 adopts the terylene yarn.
Of the present utility model three axial tricots, its layer can be arranged by following order: bottom is first layer, and the intermediate layer is second layer, and top layer is the 3rd layer.
Of the present utility model three axial tricots, the angle of its yarn of spreading and density are provided with rationally, and grammes per square metre has reached specified standard grammes per square metre 1245 ± 3%g/m
2, adopt its wind power generation blade of producing can satisfy the instructions for use of wind power plant well.
