Description

Technical Field

[0001] This invention relates to the field of curtain fabric technology, and in particular to a curtain fabric surface protection process. Background Technology

[0002] Existing tire cord fabrics generally have limited fire resistance and are significantly affected by temperature. Prolonged use in high-temperature environments can severely damage their overall performance and compromise safety. While multi-layering the main body material can improve durability, its insulation properties remain unsatisfactory, and the multi-layer structure increases production costs. Furthermore, the lack of interlocking anti-loosening structures between the tire cord fabric and the rubber main body during tire or conveyor belt production results in poor overall anti-detachment performance and low bonding strength. This negatively impacts the overall lifespan in applications with high tensile or frictional forces. Summary of the Invention

[0003] The purpose of this invention is to provide a protective process for tire cord fabric, which enables the overall tire cord fabric to have reliable anti-permeability, anti-wear, and flame-retardant properties during use, resulting in better safety and a wider range of applications. By integrating a multi-layer protective structure with a single-layer tire cord fabric substrate as the main body and fastening the assembly during the impregnation process, the overall structure has better compactness, resulting in better overall external anti-wear performance, higher overall structural strength, and a longer service life. This invention can replace the existing production and processing methods of multi-layered tire cord fabric materials, effectively saving costs in later use. Furthermore, it provides better fusion and stability with the rubber main molding material during later use, resulting in reliable tensile strength and an enhanced service life after molding.

[0004] The technical solution of the present invention is as follows: A protective process for curtain fabric is characterized by the following steps: After impregnation and drying of both sides of the woven curtain fabric material, a mesh-like breathable fabric is formed by pressing with rollers. The mesh-like breathable fabric is made of flame-retardant material and woven together. The mesh of the mesh-like breathable fabric forms a polygonal structure. An adhesive coating is applied to the surface and interior of the mesh-like breathable fabric to form an integral protective and wear-resistant layer. The adhesive coating is applied while the fabric is fully impregnated in an impregnation container. After curing, the integral protective and wear-resistant layer forms a protective layer. The interior of the mesh of the mesh-like breathable fabric is coated with adhesive. The adhesive material, wherein the outer thickness of the overall protective abrasion-resistant layer extending beyond the outer surface of the mesh-like breathable fabric is less than 0.2 mm, is then dried and stretched for shaping. A waterproof coating is applied to both sides of the shaped material using two sets of rollers. The waterproof coating is completely immersed in the waterproof coating material. After curing, the waterproof coating forms an outer protective film. The mesh-like breathable fabric, the overall protective abrasion-resistant layer, and the outer protective film are all flexible structures after molding, allowing for bending or folding along with the entire fabric. During the curing and molding process, the overall protective abrasion-resistant layer is reinforced and stabilized with a clamping column, providing a reinforcing and stabilizing molding groove.

[0005] Furthermore, the mesh-like breathable fabric is provided with staggered and evenly distributed embossed reinforcing grooves, which penetrate the width direction of the mesh-like breathable fabric, and the interior of the embossed reinforcing grooves is coated with adhesive material.

[0006] Furthermore, the mesh-like breathable fabric is made of polypropylene.

[0007] Furthermore, a heat-resistant insulating protective layer is provided on the outer side of the outer protective film.

[0008] Furthermore, the outer thickness of the overall protective abrasion-resistant layer extending beyond the outer surface of the mesh-like breathable fabric is 0.15 mm.

[0009] Furthermore, the depth of the reinforced and stabilized molding groove is less than half the wall thickness of the overall protective wear-resistant layer.

[0010] The beneficial effects of this invention are: 1. This invention enables the overall cord fabric to have reliable anti-permeability, anti-wear and flame-retardant properties during use, resulting in better safety and a wider range of applications. By using a single-layer cord fabric substrate as the main body to integrate multiple protective structures together, and by fastening the combination during the impregnation process, the overall structure is more compact, resulting in better overall external anti-wear performance.

[0011] 2. The overall structure has high strength and a longer service life. It can replace the existing production and processing method of multi-layered cord fabric materials, effectively saving the cost in the later use. The fusion and stability between the cord fabric and the main rubber molding material is better in the later use. After molding, it has reliable tensile strength and its service life can be effectively enhanced.

[0012] 3. It has a wider range of applications and can meet the performance stability requirements in high-temperature environments, making the products made from the fabric more stable and durable. Detailed Implementation

[0013] A new protective process for tire cord fabric produces products with more stable performance, providing reliable impermeability, abrasion resistance, and flame retardancy during use. This enhances safety and expands the range of applications. By integrating a multi-layer protective structure using a single-layer tire cord fabric substrate as the main body and tightening the assembly during the impregnation process, the overall structure achieves better compactness, resulting in improved external abrasion resistance, higher overall structural strength, and a longer service life. This process can replace existing multi-layered tire cord fabric production methods, effectively saving on later-stage costs. Furthermore, it improves the fusion stability between the fabric and the rubber molding material, providing reliable tensile strength and extending service life after molding. During production, both sides of the woven tire cord fabric are impregnated with adhesive, dried, and cured, then pressed together with rollers to create a mesh-like breathable fabric layer. The impregnation, drying, and curing processes are identical to those in existing production processes. During roller pressing, two sets of roller assemblies are used in conjunction, with the cord fabric material passing between them for pressing. The mesh-like breathable fabric is made of flame-retardant material through weaving. The mesh of the breathable fabric forms a polygonal structure, resulting in better deformation uniformity during subsequent overall stretching. After molding, it ensures greater overall structural strength and improved wear resistance. Cord fabric products produced using this method can have wear resistance increased by more than 2.3 times, effectively extending their overall service life and reducing operating costs. The surface and interior of the mesh-like breathable fabric are coated with an adhesive to form a protective wear-resistant layer. The adhesive coating is applied while the fabric is fully immersed in the adhesive container. After curing, the protective wear-resistant layer forms a protective layer. The interior of the mesh of the breathable fabric is filled with adhesive material, ensuring better overall structural tightness, higher overall tensile strength, and stronger shock resistance during use. The outer thickness of the overall protective abrasion-resistant layer extending beyond the outer surface of the mesh-like breathable fabric is less than 0.2mm, resulting in a relatively thin overall thickness and smaller footprint during use, meeting the safety requirements of products with larger space constraints. After drying and stretching, a waterproof coating is applied to both sides of the shaped material using a combination of upper and lower rollers. The waterproof coating process involves complete immersion in the waterproof coating material. After curing, the waterproof coating forms an outer protective film, providing better external protection and improving overall waterproof, isolation, and impermeability properties. This meets the needs of use in some special environments.The mesh-like breathable fabric, the overall protective abrasion-resistant layer, and the outer protective film are all flexible structures after molding, allowing them to be bent or folded along with the overall fabric. During the curing process, the overall protective abrasion-resistant layer is equipped with reinforcing and stabilizing grooves in conjunction with the clamping posts. When used in subsequent production and processing with the rubber base material to create new products, this ensures a stable, interwoven structure. Compared to existing fabrics, this method significantly improves strength and extends service life when used in conjunction with rubber materials.

When used in later production processes with the rubber main material to create new products, this ensures a stable, interwoven structure. The mesh-like breathable fabric features evenly distributed, interwoven, embossed reinforcing grooves that penetrate the width of the fabric. These grooves are coated with adhesive material, improving the overall fire-resistant performance of the fireproof layer structure, enhancing structural stability, and providing better flame retardancy during use.
