Summary of the invention
The purpose of the present invention is to propose to a kind of high-performance fiber axial fabrics and its production methods, improve the life of composite material
Process is produced, the performance of composite material enhancing fabric is improved.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of production method of high-performance fiber axial fabrics, it is characterised in that including five steps:
The first step, according to 0 ° of fabric through to grammes per square metre and high-performance fiber thickness, determine the head line of 0 ° of warp thread, high-performance
Fiber is mainly the carbon fibre thread of 24K-50K, and transmission job order is successively are as follows: high-performance fiber tube hangs over the corresponding of creel
In yarn shaft, yarn is pierced by wide by multiple tracks yarn passing rod, the double-deck yarn yarn sley, warp let-off roller, jockey pulley, yarn respectively from tube
Enter woven extent after spending positioning guide wheel, jockey pulley and press roller;
Second step, in the lower layer of 0 ° of warp thread, by polyaxial oblique paving Weft handling device by glass fibre hot melt wire by two layers of friendship
The mode of fork is spread into then by being transferred to woven extent with the chain belt for hanging yarn hook, the specification of hot melt wire is 75TEX glass fibre
Hot melt wire, the angle spread are adjusted between+- 30 to+- 60 degree;
Third step, through to High performance fiber layer and oblique glass fibre hot melt wire layer synchronize proceed to woven extent after, lead to
Binding let-off motion, comb section traverse displacement unit, warp knit looping device are crossed, yarn layer is woven by fabric using polyester DTY yarn;
4th step, woven fabric drive to hot melt wire heating device, set temperature according to hot melt wire fusing point, pass through
Natural cooling and fibrous layer are bonded into an overall structure after the device;
5th step, the fabric construction bonded cut into the width of design by cutting device, into pulling, batch dress
It sets, winding is completed.
Preferably, the group of warp-wise yarn described in first step creel uses the lateral yarn creel with rotation yarn, each
Tube has independent tension controlling member, is consistent with controlling the tension of yarn,
Preferably, the transmission job order in the first step is successively are as follows: high-performance fiber tube hangs over the corresponding yarn of creel
On cylinder axis, yarn from tube be pierced by respectively by first of yarn passing rod, the first double-deck yarn yarn sley, Intermediate yarn yarn passing rod,
The second double-deck yarn yarn sley, warp let-off roller, the first jockey pulley, yarn width positioning guide wheel, the second jockey pulley, third jockey pulley,
Press roller, subsequently into woven extent.
Preferably, in second step hot melt wire spread into sequence are as follows: glass fibre hot melt wire passes through from yarn on the creel of side
Then yarn porcelain eye, tension force intermediate plate, dividing sinker porcelain eye, yarn roller, poly- yarn porcelain eye excessively are pressed into polyaxial oblique paving yarn feeding device
The interval of yarn as needed is linked on the chain band with extension yarn hook of equipment Synchronous Transmission by the mode of two layers of intersection, and is driven
To woven extent;
Preferably, the knitting zone is made of binding let-off motion 12 and warp knit looping device 13.
The high-performance fiber axial fabrics prepared by the above method comprising warp direction spreads the high property into main structure
Energy fibrous layer, spreads the weft fiber layer into 30-60 degree direction for one layer at the back side of fabric, spreads into negative for two layers at the back side of fabric
The weft fiber layer in 30-60 degree direction, then above-mentioned fibrous layer is woven by warp knit binding by dacron thread and constitutes an entirety knot
Structure is finally bonded using hot-working by broadwise bilayer and the structure through being thermal bonding to a fixing-stable to layer.
Preferably, the fiber of the High performance fiber layer is high-strength and high-modulus glass fibre, carbon fiber or aramid fiber.
Preferably, the weft fiber layer uses glass fibre hot melt wire, specification 75TEX.
Preferably, the fiber dimensious of the High performance fiber layer is 1500TEX-3300TEX.
Preferably, the density of the High performance fiber layer is 4.5-10 pieces/inch, 600 grams of fiber Unit Weight.
It is laid with the invention has the following advantages: hanging creel by 0 ° of yarn of installation, it is equal to control every one thread tension
It is even consistent, it is ensured that the flatness and uniformity of yarn object, laying and bonder by using hot melt wire line improve tissue layer
Between structural stability can, prevent fabric distortion, the mechanical property of stable fabric has better specific strength and specific modulus.
Specific embodiment
The present invention is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, being the structure chart of 0 ° of warp thread laying apparatus in equipment, yarn is pierced by from tube creel 1, passes through respectively
Cross first of yarn passing rod 2, second bilayer yarn sley 3, third road centre yarn passing rod 4, the 4th bilayer yarn sley 5, by sending
Through roller 6, the first jockey pulley 7, breadth positioning guide wheel 8, the second jockey pulley 9, third jockey pulley 10, press roller 11, into knitting zone
Domain, by hot melt wire heating device 14 after weaving textile, pulling roller 15 batches 16, completes production process, the knitting zone by
Binding let-off motion 12 and warp knit looping device 13 are woven, and the double-deck yarn sley and jockey pulley control play holding
The effect of yarn distribution and even tension, makes yarn tension entirety excellent in uniform on 0 degree.The hot melt heating device is by 0
Spend the structure that the yarn being evenly distributed and back side bilayer hot melt wire form a fixing-stable by thermal consolidating, it is ensured that fabric construction
Stability, play the role of mentioning high performance.
It is the structure chart of positive and negative 60 ° of weft yarn laying apparatus in equipment shown in Fig. 2, weft yarn is drawn from tube creel 17, point
Not Jing Guo yarn porcelain eye 18, tension force intermediate plate 19, dividing sinker porcelain eye 20, cross yarn roller 21, poly- yarn porcelain eye 22, Weft laying trolley 23, into
Enter polyaxial oblique paving Weft handling device, the band that yarn is linked into equipment toothed belt transmission is then hung into yarn hook in such a way that two layers intersects
Chain band on, and be transferred to knitting zone.
Through to High performance fiber layer and oblique glass fibre hot melt wire layer synchronize proceed to woven extent after, sent by binding
Through device, comb section traverse displacement unit, warp knit looping device, yarn layer is woven by fabric using polyester DTY yarn;Woven fabric
Hot melt wire heating device is driven to, temperature is set according to hot melt wire fusing point, natural cooling and fibrous layer are viscous after the device
Synthesize an overall structure;The fabric construction bonded cuts into the width of design by cutting device, into pulling, batch dress
It sets, winding is completed.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
