Description

Device for manufacturing fiber bundle forming semi-cooked impregnated fiber bundle and manufacturing method thereof

The present invention relates to fiber cloth, and more particularly to a fiber bundle forming apparatus and method for forming a semi-cooked impregnated fiber bundle.

According to the press, all the fabrics are interwoven with a plurality of fiber bundles, and the application of the fiber fabric is deep and wide, and the fabrics are used from the clothing, the outer surface of the equipment, and even the building materials, and the quality of the fabrics of these fabrics is In connection with the properties of fiber cloth, fiber cloth is usually subjected to a process of gluing and bonding, so that the finished product of the fiber cloth is not easily softened after hardening, or the finished product of the fiber cloth is laminated with multiple layers of fiber cloth to increase its thickness or The strength, the finished fabric of the fiber cloth or the single layer or multi-layer lamination, through the layer impregnation of the layers, or the single layer or multiple layers of the same glue, the surface of the fiber cloth can be glued, but the existing products have poor adhesion, the glue layer The poor adhesion between the gas and the adhesive layer or the peeling between the adhesive layers will reduce the strength, rigidity and elasticity of the finished fabric.

However, the above-mentioned shortcomings of the fiber cloth products have the above disadvantages, as shown in Figures 1 and 2, because the conventional fiber cloth is sizing by first making the plurality of fiber bundles 1 into a whole piece of cloth 2, and then the whole piece The cloth 2 is immersed in the glue, or the cloth 2 is first placed in a molding die, and then the glue is poured into the molding die, and the sizing method can only form a rubber layer on the surface layer of the cloth 2, and the cloth cannot be made. 2 The inside of each bundle of fiber bundles 1 is indeed impregnated, and even the surface of the fiber bundle 1 cannot be completely and completely applied to the rubber layer 3, but the inside of the fiber bundle 1 is insufficiently impregnated due to natural impregnation. That is, the industry claims that the impregnation rate is insufficient, and the structure itself is extremely loose. Therefore, after the impregnated rubber is cured, the bonding force between the fibers in the fiber bundle 1 is very limited, and the strength of the overall curing is greatly adversely affected. The incomplete contact A of the plurality of fiber bundles 1 or the glue close to the contact point A cannot flow in, and the higher the stickiness of the glue, the more difficult it is for the glue to penetrate the surface of the fiber bundle 1 and contact each other with A, resulting in When 3 where the lack of the adhesive layer 2 results in a whole formed into a finished fabric, the fiber bundle layers or between a fiber bundle of a bonding strength, rigidity and lack of elasticity and so on.

Therefore, how to improve the lack of strength, rigidity and elasticity of conventional fiber fabrics is the primary research and development topic of the present invention.

The present invention provides a fiber bundle forming semi-maturing impregnated fiber bundle device and a manufacturing method thereof, the main purpose of which is to utilize a high impregnation rate inside a single fiber bundle and a resin having a high bonding property in the outer layer, thereby improving each fiber bundle in the fabric. The viscosity between the two increases the overall strength, rigidity and elasticity of the fabric.

In order to achieve the above object, the present invention provides a fiber bundle forming semi-cooked impregnated fiber bundle device and a manufacturing method thereof, comprising: a feeding step of providing at least one fiber bundle to a bundle of wheels; a roughening step is provided a negative pressure chamber, wherein the negative pressure chamber is provided with an arc generator, wherein the arc generator generates a continuous discharge gas to produce the plurality of potholes on the surface of the fiber bundle, and the negative pressure chamber generates a negative pressure to absorb a pothole dust produced by the roughening treatment mechanism and a vacuum state in which a negative pressure is formed inside the fiber bundle; a resin molding step of attaching a resin to the inside of the fiber bundle by a continuous screw to improve impregnation of the resin And forming a resin outer layer on the surface; a half-aging forming step, externally molding the resin and forming a semi-cured state by controlling the temperature and pressure to strongly bond the inside of the fiber bundle; and a winding step of the semi-cooked fiber bundle After being formed into an impregnated fiber bundle, the film is wound up to provide a subsequent weaving into a cloth; by the above steps, the surface of each fiber bundle is formed into a resin outer layer, The pothole can be surely bonded to the outer layer of the resin coated on the surface of the fiber bundle, so that the internal impregnation rate of the plurality of fiber bundles is extremely strong, and the fiber bundles are simultaneously contacted by molding the outer layer of the resin. When it is applied to the place, the bonding force between the layers of the fiber bundles or the fiber bundles is stronger because of the application of the adhesive or the bundle of the viscose fibers, thereby improving the overall strength, rigidity and elasticity of the finished product.
