The invention discloses a method for preparing a threadlike carbon heat source material for cigarettes by using acid, which comprises the following steps: mixing sodium alginate or ammonium alginate or potassium alginate with carbon powder and water, and stirring into a jelly, wherein the mass ratio of the sodium alginate or ammonium alginate or potassium alginate to the carbon powder is 1:(5-45); extruding the jelly into a thread, and sufficiently contacting the thread with an acidic solution with the pH value of at most 3 to obtain a condensate; and rinsing the condensate, and drying until the water content reaches 10-20%, thereby obtaining the threadlike carbon heat source material for cigarettes. The invention lowers the hazard caused by glass fibers sucked into the human body, enhances the combustibility of the carbon heat source, and has the characteristics of simple method, short production cycle, low cost and the like.
