Description

A kind of three axial tricots

Technical field

The utility model relates to a kind of fabric that forms by the warp knitting machine braiding, 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, as present widely used a kind of three axial glass fibre tricots, the 3rd layer that the weft yarn arrangement of 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 or 90 degree directions constitute and first, second and the binding of the 3rd layer are woven the bundled yarn that becomes one constitute; When braiding, first layer that the weft yarn arrangement of positive 45 degree directions constitutes is a bottom, and the intermediate layer is the 3rd layer that the warp thread or 90 of zero degree direction is spent the weft yarn arrangement formation of directions, and top layer is second layer of the weft yarn arrangement formation of negative 45 degree directions.The fabric of this structure is when bonding process, because the sequence and the density of the yarn of spreading are provided with unreasonable in this fabric, thereby it is slow as seepage velocity the process of osmosis of resin from bottom to top layer of adhesive, do not reach the seepage velocity of regulation, thereby cause its production cycle longer, production efficiency is lower, can't satisfy the growing market demand.

The utility model content

The technical problems to be solved in the utility model provides a kind of density of spreading yarn and is provided with rationally, thereby can improve three axial tricots of the seepage velocity of resin and production efficiency.

For solving the problems of the technologies described above, the utility model adopted a kind of three axial tricots, the 3rd layer that second layer that the weft yarn arrangement of its first layer that is made of the weft yarn arrangement of 90 degree directions, positive 45 degree directions constitute, the weft yarn arrangement of negative 45 degree directions constitute and will be described first, second and the binding of the 3rd layer weaves that become one and bundled yarn that be positioned at the zero degree direction constitutes; Number number of the weft yarn of described 90 degree directions is 2400tex, and number number average of the weft yarn of described positive and negative 45 degree directions is 300tex, and number number of the bundled yarn of described zero degree direction is 8.3tex; The density of the weft yarn of described 90 degree directions is 295 pieces/meter, and the density of the weft yarn of described positive and negative 45 degree directions is 590 pieces/meter, and the density of the bundled yarn of described zero degree direction is 236 pieces/meter, and the density of the coil on described bundled yarn is 350/meter.

The weft yarn of the weft yarn of the weft yarn of described 90 degree directions, positive 45 degree directions and negative 45 degree directions is glass fiber yarn, and described bundled yarn is the terylene yarn.

After adopting such structure, because the weft count of 90 degree directions adopts 295 pieces/meter, the density of positive and negative 45 degree direction weft yarns all adopts 590 pieces/meter, the density of the bundled yarn of zero degree direction adopts 236 pieces/meter, the density of the coil on bundled yarn is 350/meter, and the fabric that is made of this thread density structure is for existing fabric, under the situation that guarantees fabric quality, its resin penetration speed has improved more than 10%, thereby improved the production efficiency of fabric, satisfied the market demand better.

As a kind of improvement 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, because bottom is the layer that layer, intermediate layer and the top layer of 90 degree directions is respectively positive and negative 45 degree directions, this layer with 90 degree directions places outermost layer but not the intermediate layer, be convenient to that resin can at first directly contact this layer when bonding process, thereby more help accelerating the seepage velocity of resin, production efficiency is higher, and the structure of fabric is more reliable, in use reaches 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 a kind of three axial tricots shown in Fig. 1,2, the weft yarns 3 that the weft yarn 2 that its weft yarns 1 by 90 degree directions are arranged first layer that constitutes, positive 45 degree directions is arranged second layer that constitutes, negative 45 degree directions arrange the 3rd layer that constitutes and will be described first, second and the binding of the 3rd layer weaves that become one and bundled yarn 4 that be positioned at the zero degree direction constitutes; Number number of the weft yarn 1 of described 90 degree directions is 2400tex, and number number average of the

weft yarn

2,3 of described positive and negative 45 degree directions is 300tex, and number number of the bundled yarn 4 of described zero degree direction is 8.3tex; The density of the weft yarn 1 of described 90 degree directions is 295 pieces/meter, the density of the

weft yarn

2,3 of described positive and negative 45 degree directions is 590 pieces/meter, the density of the bundled yarn 4 of described zero degree direction is 236 pieces/meter, and the density of the coil 4-1 on described bundled yarn 4 is 350/meter.This fabric, the grammes per square metre of 90 degree direction weft yarns is 709g/m ², the grammes per square metre of positive and negative 45 degree direction weft yarns is 251g/m ², the bundled yarn grammes per square metre is 7g/m ², the fabric of this structure has improved more than 10% resin penetration speed, thus the production efficiency height can satisfy the growing market demand better, and this fabric weight reached standard-required, and promptly the grammes per square metre of fabric is 1215 ± 3%g/m ²Thereby, guaranteed the quality requirement of fabric at aspects such as intensity, weight, guaranteed safe, the normal use of equipment such as wind-power electricity generation better.
