Description

Technical Field

[0001] This utility model belongs to the field of inorganic materials technology and relates to a composite yarn of glass fiber and quartz fiber. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material characterized by high drawing strength, high temperature resistance, good insulation, and chemical fiber stability. Compared with glass fiber, quartz fiber is superior in mechanical strength and physicochemical properties, but its cost is much higher. In addition, both glass fiber and quartz fiber are brittle, resulting in products with poor flexibility and low impact resistance. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a composite yarn of glass fiber and quartz fiber. The technical problem to be solved by this invention is to provide a low-cost inorganic composite yarn.

[0004] The purpose of this utility model can be achieved through the following technical solution: a composite yarn of glass fiber and quartz fiber, characterized in that it includes a core material and an outer covering layer, wherein the core material includes multiple twisted quartz fiber bundles, and the outer covering layer includes multiple glass fiber bundles twisted outside the core material, wherein the quartz fiber bundles, the glass fiber bundles, and the quartz fiber bundles and glass fiber bundles are all bonded together by glass fiber adhesive.

[0005] Furthermore, the fiberglass adhesive forms a protective layer outside the outer coating.

[0006] In this way, not only can the amount of quartz fiber used be greatly reduced, thus lowering the raw material cost of composite yarn, but the bundle properties can also be improved with the help of glass fiber adhesive. By twisting and bonding, the flexibility of the composite yarn can be improved, resulting in fabric products with better flexibility and higher impact resistance. Attached Figure Description

[0007] Figure 1 This is a cross-sectional view of the composite yarn.

[0008] In the diagram, 1 represents a bundle of quartz fibers; 2 represents a bundle of glass fibers. Detailed Implementation

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] like Figure 1The composite yarn shown includes a core and an outer cladding. The core comprises multiple twisted quartz fiber bundles 1, and the outer cladding comprises multiple twisted glass fiber bundles 2 outside the core. The quartz fiber bundles 1, the glass fiber bundles 2, and the quartz fiber bundles 1 and glass fiber bundles 2 are all bonded together with glass fiber adhesive. During processing, adhesive application and twisting can be carried out simultaneously. Less adhesive is applied when twisting the quartz fiber bundles 1, while more adhesive can be applied when twisting the glass fiber bundles 2 outside the core. The twisting directions of both are the same. The glass fiber adhesive can be epoxy resin adhesive commonly used in the processing of existing glass fiber products.

[0011] Fiberglass adhesive forms a protective layer outside the outer coating. In other words, fiberglass adhesive can be used only for bonding between filament bundles, or it can be applied in larger quantities to form a protective layer on the outer surface of the composite yarn.

[0012] In this way, not only can the amount of quartz fiber used be greatly reduced, thus lowering the raw material cost of composite yarn, but the bundle properties can also be improved with the help of glass fiber adhesive. By twisting and bonding, the flexibility of the composite yarn can be improved, resulting in fabric products with better flexibility and higher impact resistance.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
