Abstract

The invention discloses a preparation method of monofilament with an adsorption function. The preparation method comprises the following steps of soaking active ball carbon in acid liquor for a set time; mixing the soaked active ball carbon with polyamide resin slurry to form mixed slurry; and placing the mixed slurry in a coating groove, and coating polyamide monofilament or polyamide multifilament with the mixed slurry through the coating groove. According to the technical scheme provided by the embodiment of the invention, the active ball carbon is soaked in the acid liquor and is subjected to acid treatment, so that pores in the active ball carbon are effectively protected; and meanwhile, the acidic polyamide resin solution and the active ball carbon subjected to acid treatment are mixed, so that the binding force between the active ball carbon and the polyamide monofilament is improved, the prepared monofilament has the relatively high adsorption function, meanwhile, the binding between the active ball carbon and the monofilament is relatively firm, and the wear resistance of the monofilament with the adsorption function is guaranteed.

Description

technical field [0001] The invention generally relates to the field of monofilaments, in particular to a method for preparing monofilaments with adsorption function. Background technique [0002] Activated carbon has developed pore structure and large surface area. As an effective adsorbent, it is widely used in the field of environmental protection to treat waste water, waste gas, waste solvents, etc. In the field of fabrics and fibers, activated carbon is usually adhered to its surface with an adhesive to endow the fabric or Fiber adsorption function, often used in protective clothing, protective masks, adsorption devices, etc. [0003] The activated carbon particles prepared by coating the fabric substrate with glue and grinding are evenly distributed on the fabric substrate under the action of hot rolling to form an activated carbon adsorption layer, and then cover it with a layer of non-woven fabric to prevent the activated carbon from rubbing and peeling off.
