Problems solved by technology

The production process of electrospinning: 1. The production efficiency is low, and the production process of electrospinning takes a long time, so it takes a lot of time; 2. The control factors are much more complicated than the traditional spinning process, such as voltage, flow, Spinning distance, humidity, and temperature will all affect the quality of the final spun silk; 3. The equipment cost is high, and the general electrospinning process equipment includes high voltage, pump, wire splicer, controllable 4. The consistency of the product is relatively unstable

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a method for preparing graphene / polyamide 6 composite fibers. Background technique [0002] Polyamide 6 itself has excellent comprehensive properties such as wear resistance, oil resistance, self-lubrication, insulation, excellent mechanical properties, easy processing and molding, and weak acid and alkali resistance, but ordinary polyamide 6 also has the defects of low dry state and low temperature impact strength. , so that its application is limited to a certain extent, and it cannot meet the needs of high-strength materials in industries such as automotive electronics and machinery. Various methods have been used to toughen and modify ordinary nylon at home and abroad. The toughened polyamide 6 is widely used in transportation, electronic appliances, consumer goods, machinery industry and other industries. [0003] Since 1935, Carothers, an outstanding scientist in ...
