Abstract

The utility model provides a uniaxial warp knitted fabric consisting of a first yarn layer, a second yarn layer and a binding yarn, wherein the first yarn layer is formed by the arrangement of a plurality of warps along with the zero-degree direction, the second yarn layer is formed by the arrangement of pieces of M67 thin clothes along with the 90-degree direction, and the binding yarn is integrated the first yarn layer with the second yarn layer and is arranged along with the zero-degree direction. The warp along with the zero-degree direction adopts the high-modulus warps with the number of 2400 tex and the density of 468 numbers/meter; the M67 thin clothes along with the 90-degree direction has the gram weight of 67 g/m<2> in each unit area; and the binding yarn has the number of 8.3 tex, the density of 275 numbers/meter, the stitch density of 185 numbers/meter, and the gram weight of 13 g/m<2> in each unit area. The weft yarn bend can be greatly reduced, and the production efficiency can be improved. Therefore, the gram weight of the textile fabric in each unit area can be accurate at 1200 g/m<2>. A wind power generating blade made by the uniaxial warp knitted fabric can preferably meet the use requirement of a wind driven generator.

Description

A kind of single shaft is to tricot

Technical field

The utility model relates to a kind of reinforcing material of making wind power generation blade, ships and light boats etc., and particularly a kind of single shaft is to tricot.

Background technology

Tricot as reinforcing materials such as wind power generation blade, ships and light boats; Especially a kind of one-way glass fiber tricot that can be widely used in the main force part of blade-----girder; The one-way glass fiber tricot that uses at present causes 90 degree direction weft yarn bendings and production efficiency low easily.

Summary of the invention

The technical problem that the utility model will solve is the deficiency to prior art, has proposed a kind of single shaft that significantly reduces the weft yarn bending and improved production efficiency to tricot.

The technical problem that the utility model will solve realizes through following technical scheme; A kind of single shaft is characterized in to tricot: arrange that first layer that constitutes, the thin cloth of M67 that 90 degree directions are laid are arranged second layer that constitutes and that become one and bundled yarn that be positioned at the zero degree direction constitutes with first and second layers binding braiding by the warp thread of zero degree direction.

The technical problem that the utility model will solve can also further realize through following technical scheme; The warp thread of zero degree direction adopts the warp thread of high-modulus; Its number number is 2400 tex, and the density of warp thread is 468 pieces/meter, and the thin cloth unit are grammes per square metre of 90 degree direction M67 is 67g/m ², number number of bundled yarn is 8.3 tex, and the density of bundled yarn is 275 pieces/meter, and the loop density on bundled yarn is 185/meter, and the unit are grammes per square metre is 13g/m ²

The technical problem that the utility model will solve can also further realize that the thin cloth of M67 that the warp thread of said zero degree direction, 90 degree directions are laid is glass fiber yarn through following technical scheme, and zero degree direction bundled yarn is the polyester DTY network yarn.

The utility model compared with prior art, 90 degree directions adopt thin cloth to replace the 300tex weft yarn, significantly reduce weft yarn crooked with improved production efficiency.The unit are grammes per square metre of fabric can be accurate to 1200 gram/m like this ²The wind power generation blade that is used for producing can satisfy the instructions for use of wind power plant well.

The specific embodiment

A kind of single shaft is to tricot, arranges that first layer that constitutes, the thin cloth 2 of M67 that 90 degree directions are laid are arranged second layer that constitutes and that become one and bundled yarn 3 that be positioned at the zero degree direction constitutes with first and second layers binding braiding by the warp thread 1 of zero degree direction.

The warp thread of zero degree direction adopts the warp thread of high-modulus, and its number number is 2400 tex, joins the needle-bar of 7 pins with the reed of 12 pins; The unit are grammes per square metre is accurate to 1120g/m2, and the density of warp thread is 468 pieces/meter, and the thin cloth of 90 degree directions is 67g/m2 grid screen cloth; Number number of bundled yarn is 8.3 tex, and the density of bundled yarn is 275 pieces/meter, and the loop density on bundled yarn is 185/meter; The unit are grammes per square metre is 13g/m2, and the unit are grammes per square metre of fabric can be accurate to 1200g/m2 like this.

The thin cloth 2 of M67 that warp thread 1, the 90 degree directions of said zero degree direction are laid is glass fiber yarn, and zero degree direction bundled yarn 3 is the polyester DTY network yarn.

Claims

1. a single shaft is characterized in that to tricot: arrange that first layer that constitutes, thin cloth that 90 degree directions are laid are arranged second layer that constitutes and that become one and bundled yarn that be positioned at the zero degree direction constitutes with first and second layers binding braiding by the warp thread of zero degree direction.

2. single shaft according to claim 1 is characterized in that to tricot: the warp thread of zero degree direction adopts the warp thread of high-modulus, and its number number is 2400 tex, and the density of warp thread is 468 pieces/meter, and the thin cloth unit are grammes per square metre that 90 degree directions are laid is 67g/m ², number number of bundled yarn is 8.3 tex, and the density of bundled yarn is 275 pieces/meter, and the loop density on bundled yarn is 185/meter, and the unit are grammes per square metre is 13g/m ²

3. single shaft according to claim 1 is characterized in that to tricot: the thin cloth that the warp thread of said zero degree direction, 90 degree directions are laid is glass fiber yarn, and zero degree direction bundled yarn is the polyester DTY network yarn.
