Product description

 

 DescriptionGraphene is a two-dimensional materialconsisting of a single layer of carbon atoms arranged in a honeycomb structure. Its properties include high strength and good conductivity of heat and electricity. The stacked form of graphene is graphite.Graphene conductive fibers are chemical fibers spun from graphite carbon black mixed with conductive media in polymers.The performance of graphene conductive fibers in eliminating and preventing static electricity is much higher than that of antistatic fibers, and the resistance value is stable, lasting and basically not affected by humidity.
Characteristic of Graphene fibersUltra-strong far infrared deep skin care 
 Anti-ultraviolet radiation, tbeauty and skin care
 Microcirculation, Improve Metabolism
Antibacterial and bacteriostatic, self-cleaning and skin-nourishing
 Energy application of Alkene
 Anti-static
 FeaturesRadiation protection、Dust proof、Conductive、Heat conduction

 

The following is the washing standard for graphene composite conductive yarn woven into garments:

 

Before testing the Electric charge of the anti-static wool knitted clothing, it should be washed in accordance with the prescribed method. The washing time is 6.5 hours, which is the same as the washing method in GB12014-2009 "Anti-static clothing" standard. The neutral detergent is used to wash continuously at low grade and the water temperature is room temperature.The Electric charge of the anti-electric wool knitted clothes was tested after washing, and the result was not more than 0.60 mC/piece. The test method adopted the national standard GB 12014-2009 "Anti-static clothing" to test the Electric charge of clothing. The environmental temperature and relative humidity of the test were (20±5)°C and (30+5)%. The wool knitted clothes were tested in a drum friction machine after 15 minutes of friction. The inner diameter of the drum friction machine was (65 + 5) cm, the depth of the drum was (45 + 5) cm, and the inner material of the drum was polymer.
