A precious metal pattern cloth and a production process thereof

Abstract

This invention discloses a precious metal patterned fabric, comprising a woven fabric composed of precious metal wires of various diameters. These wires are formed by interlacing multiple strands of rolled precious metal wires, with each strand having a diameter of 0.05mm-0.08mm. The production process includes: step one, precious metal casting; step two, wire rolling treatment; step three, wire extrusion coating treatment; step four, precious metal fabric weaving; step five, coating material removal; and step six, cleaning and coating treatment. This invention improves the tensile strength and elongation of the precious metal wires to a level suitable for weaving precious metal patterned fabrics by subjecting the precious metals to an oxygen-free treatment followed by continuous rolling, combined with polyurethane coating treatment. This makes it possible to weave precious metal patterned fabrics, significantly reducing breakage rate and increasing yield. Subsequent nano-coating treatment adds a protective film to the fabric, further enhancing the oxidation resistance of the precious metal alloy.

Description

Technical Field

[0001] This invention relates to the field of jewelry and decorative technology, and in particular to a precious metal patterned fabric and its production process. Background Technology

[0002] Precious metals mainly refer to gold, silver, and platinum group metals. These precious metals mostly have beautiful colors. Goods made from these precious metals with certain patterns and / or shapes are called precious metal ornaments. Precious metal ornaments mainly serve an ornamental function and a value storage function, and are very popular.

[0003] Since precious metals are generally soft, current methods for weaving precious metal threads involve mixing them with cotton yarn or synthetic yarn to form composite precious metal threads for fabric weaving. This method cannot achieve the manufacture of high-purity precious metal ornaments, and the weaving process with single precious metal threads is very prone to thread breakage, affecting the integrity and aesthetics of the pure precious metal fabric weaving. Therefore, this invention proposes a precious metal patterned fabric and its production process to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a precious metal patterned fabric and its manufacturing process. This precious metal patterned fabric and its manufacturing process involve subjecting precious metals to an oxygen-free treatment followed by continuous rolling, combined with polyurethane coating treatment. This increases the tensile strength and elongation of the precious metal threads to a level suitable for weaving precious metal patterned fabrics, making it possible to weave precious metal patterned fabrics and significantly reducing the breakage rate and increasing the yield. Furthermore, subsequent nano-coating treatment applies a protective film to the fabric, further enhancing the oxidation resistance of the precious metal alloys and providing a reliable weaving direction for the production of patterned fabrics.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a precious metal patterned fabric and its production process, comprising a fabric woven from precious metal wires of various diameters, wherein the precious metal wires of various diameters are interwoven from multiple strands of rolled precious metal wires, and the diameter of a single strand of the precious metal wire is 0.05mm-0.08mm.

[0006] A production process for a precious metal patterned fabric includes the following steps:

[0007] Step 1: Precious metal casting. Place the precious metal raw material into a continuous casting machine, evacuate and inject argon gas to obtain oxygen-free and hydrogen-free precious metal wire.

[0008] Step 2: Wire rolling process. The oxygen-free and hydrogen-free precious metal wire is continuously rolled using a continuous rolling mill until the diameter of the precious metal wire reaches 0.05mm-0.08mm, thus obtaining precious metal wire.

[0009] Continuous rolling can further improve the hardness of precious metals or precious metal alloys, and keep the tensile strength and elongation of precious metals within the required range.

[0010] Step 3: Wire extrusion coating process. The polyurethane material is placed in the extruder, and then the precious metal wire is passed through the extruder nozzle and discharged synchronously with the hot-melt polyurethane extrusion speed. Then it is cooled and wound up to obtain polyurethane-coated wire.

[0011] It can further improve the braiding mechanical properties of precious metal wires and prevent braiding breakage;

[0012] Step 4: Precious metal fabric weaving. Polyurethane-coated threads made from precious metal raw materials of different colors are alternately woven using a jacquard machine to obtain precious metal patterned fabric.

[0013] Step 5: Removal of the coating material. The woven precious metal patterned fabric is immersed in an ultrasonic cleaner containing anhydrous dimethyl sulfoxide organic solvent for heating and dissolution treatment, resulting in pure precious metal patterned fabric with the polyurethane coating layer removed.

[0014] Step 6: Cleaning and Coating Treatment. The pure precious metal patterned fabric obtained in Step 5 is soaked in ammonia water, then cleaned and dried. After drying, a conductive polymer is used to perform nano-coating treatment on the pure precious metal patterned fabric to obtain the finished pure precious metal patterned fabric.

[0015] A further improvement is that: after rolling in step two, the precious metal wires are treated with degreasing agent and water before entering step three. Step two also includes interlacing the rolled precious metal wires with different numbers of strands to obtain precious metal wires of different diameters.

[0016] A further improvement is that the thickness of the polyurethane coating layer on the outer layer of the polyurethane-coated filament in step three is 0.015mm-0.02mm.

[0017] A further improvement is made in the following step: during the weaving process in step four, the warp and weft threads are woven with polyurethane-coated yarns of corresponding diameters according to the pattern texture. At the same time, the weaving density and color of the warp and weft threads are controlled to weave precious metal patterned fabrics with different structural textures.

[0018] Further improvements are made in the following ways: the heating and dissolving temperature in step five is 75-90℃, and the processing time is 15-20 minutes; after obtaining the pure precious metal patterned cloth through heating and dissolving, it is rinsed with clean water.

[0019] A further improvement is made in step six, where the pure precious metal patterned fabric is ultrasonically treated in an ultrasonic cleaner containing ammonia for 5-8 minutes. After treatment, it is rinsed with clean water again and then dried at 50-70°C for 5-8 minutes to obtain the pure precious metal patterned fabric.

[0020] The beneficial effects of the present invention are as follows: The present invention improves the tensile strength and elongation of precious metal threads to the level that can be used to weave precious metal patterned fabrics by subjecting precious metals to oxygen-free treatment and continuous rolling, combined with polyurethane coating treatment. This makes it possible to weave precious metal patterned fabrics and greatly reduces the breakage rate and improves the yield.

[0021] The subsequent nano-coating process provides a protective film to limit the fabric's movement. The mass fraction of the nano-coating is insufficient to affect the mass fraction of precious metals, i.e., the purity, further enhancing the oxidation resistance of precious metal alloys. This provides a reliable weaving direction for the production of patterned fabrics and has excellent application prospects in the gold, jewelry, and decoration industries.

[0037] Step 6: Cleaning and Coating Treatment. The pure precious metal patterned fabric obtained in Step 5 is soaked in ammonia water, then cleaned and dried. After drying, a conductive polymer is used to perform nano-coating treatment on the pure precious metal patterned fabric to obtain the finished pure precious metal patterned fabric.

[0038] The pure precious metal patterned fabric is ultrasonically treated for 5-8 minutes in an ultrasonic cleaner containing ammonia. After treatment, it is rinsed with clean water and then dried at 50-70℃ for 5-8 minutes to obtain the pure precious metal patterned fabric.
