The invention discloses a binchotan 
fiber fabric, a preparation method and application. The binchotan 
fiber fabric is prepared from blended 
yarn of binchotan 
fiber and long stapled cotton fiber. The preparation method comprises the steps that warping beams are prepared, specifically, binchotan fiber blended warp 
yarn penetrates through a tentering reed on a high-speed warping 
machine, and then uniformly-arranged warping beams are formed in a lease warping method and to be used on the 
machine; the well sorted warping beams are subjected to drafting and denting, and then the warping beams are mounted on a 280cm high-speed rapier loom for 
spinning; the weft density of the 
machine is adjusted; a jacquard weaving program is well designed for an electronic jacquard machine to perform heald raising, and then weaving is performed based on 
porous composite structure regular adjusting and testing; woven greige cloth is subjected to 
dyeing treatment after being taken off the machine; and after passing inspection, the dyed greige cloth is sent to a finishing workshop for clipping, sewing, inspecting and packaging. The binchotan fiber finished product is rich in binchotan active substance, andcapable of effectively blocking electromagnetic 
waves from mobile phones, computers and televisions, thus preventing the human bodies from being hurt.
