Problems solved by technology

[0004] At present, it is necessary to use conductive non-woven fabrics in some special environments, but although the conductive non-woven fabrics produced by the existing process have certain conductive properties, their conductive properties are relatively poor and need to be further improved.
Furthermore, its own strength (mechanical properties) is relatively low, and its anti-aging and antibacterial properties are relatively poor, which seriously affects its service life and quality.

Abstract

The invention relates to the technical field of non-woven fabric preparation, in particular to a preparation method of high-strength black conductive non-woven fabric. Black polyester staple fibers, bamboo charcoal staple fibers and carbon black conductive staple fibers are used as raw materials for preparing the non-woven fabric, so that the prepared non-woven fabric has good conductivity, and further has the advantages of high strength and excellent mechanical properties. Nano-silver has good conductivity, and further effectively enhances the conductivity of the non-woven fabric through the mutual cooperation of the nano-silver and other fiber raw materials; furthermore, the nano-silver has excellent antibacterial performance, and is matched with the quaternary ammonium salt bactericide, the nano-powder and the bamboo charcoal short fibers for use, so that the prepared non-woven fabric product has a very good slow-release sterilization effect, and the service life of the non-woven fabric is prolonged; and in addition, the nano powder and 4-propenyloxy-2-hydroxybenzophenone are synergistically matched, so that the non-woven fabric product has very good anti-ultraviolet and anti-aging functions, and the quality of the non-woven fabric product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric preparation, in particular to a preparation method of high-strength black conductive non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, etc., are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. Because it is a fabric that does not need spinning and weaving, it is just oriented or random arrangement of short textile fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. [0003] Because non-woven fabrics are moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, ...
