Abstract

The invention discloses a method for preparing photocatalysis self-cleaning nanometer fiber felt. The method includes the steps that nanometer titania powder, nanometer diatom ooze powder and granules are evenly mixed and then placed in an extruder, and a mixture is extruded out at a working temperature ranging from 80 DEG C to 240 DEG C of the extruder and is cut into photocatalysis self-cleaning master batches; the photocatalysis self-cleaning master batches are added into the granules, the photocatalysis self-cleaning master batches and the granules are evenly mixed and then dissolved in an organic solvent, a mixture is stirred at an indoor temperature until complete dissolving is achieved, and then a spinning solution is prepared, wherein the concentration of solid matter ranges from 50g / L to 100g / L; electrostatic spinning is conducted through the spinning solution, and then a photocatalysis self-cleaning nanometer fiber layer is acquired; the photocatalysis self-cleaning nanometer fiber felt is acquired through compression molding. The fiber felt prepared through the method has the high specific area, can absorb and effectively decompose organic matter, decompose the peculiar smell produced in daily life, adjust the environment humidity, and can be used as a carpet, textile and garment materials, medical materials and the like.

Description

technical field [0001] The invention belongs to the field of textile materials, and in particular relates to a preparation method of a photocatalyzed self-cleaning nanofiber felt. Background technique [0002] The harmful substances in the indoor air caused by various reasons exceed the standard, and then affect the indoor environmental pollution behavior of human health. Harmful substances include formaldehyde, benzene, ammonia, radioactive radon, etc. As the level of pollution intensifies, the human body will produce sub-health reactions and even threaten life safety. Therefore, indoor air pollution is one of the human hazards that has received increasing attention. From the current detection and analysis, the main sources of indoor air pollutants mainly include the following aspects: building and interior decoration materials, outdoor pollutants, combustion products and human activities. 1) Materials such as paint, plywood, particle board, foam filler, interior wall pa...
