Abstract

The invention relates to the manufacturing field of wearable textile far-infrared heating products, in particular to a making technology of graphene conductive fiber. The technology includes: impregnating treated spinning yarn raw material with a waterborne graphene far-infrared slurry, hanging the spinning yarn raw material at a discharge end of equipment, the letting the spinning yarn raw material pass through a guide wheel for fully contacting the waterborne graphene far-infrared slurry by an immersion pool for 5-10min, also scraping the redundant waterborne graphene far-infrared slurry bya die, keeping the diameter of the spinning yarns consistent to obtain a beautiful textile product, and passing the product through a drying channel to make the spinning yarn uniform, dry and soft, conducting detection according to requirements, and taking the qualified product for stand-by use in textiles. The waterborne graphene far-infrared slurry adopted by the invention is non-toxic and harmless, causes no damage to the human body, and oil-based slurry is not recommended for use, as oil-based slurry can cause damage and harm to the human body and is carcinogenic.

Description

technical field [0001] The invention relates to the field of manufacturing far-infrared heating products of wearable textiles, in particular to a manufacturing process of graphene conductive fibers. Background technique [0002] The conductive fibers currently on the market are generally carbon fibers, such as carbon fibers, nanotube fibers, etc., which cannot be used in textile products, and are expensive, resulting in extremely high cost of the products, which are unacceptable to the public and difficult to be used in civilian products. , Clothing production. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a manufacturing process of graphene conductive fibers, the graphene conductive fibers produced have fast heating, good uniformity, low anti-attenuation cost, and make up for the deficiencies of other materials such as carbon fibers. [0004] Technical scheme of the present invention is: [000...
