Problems solved by technology

Due to the wide range of applications, the research and development of functional non-woven fabrics has attracted increasing attention. The existing functional non-woven fabrics are concentrated in the field of antibacterial, and most of them are silver-loaded antibacterial non-woven fabrics. The development and research of non-woven fabrics with other functions are still relatively insufficient

Abstract

The invention discloses a filter nonwoven fabric capable of releasing negative ions, which is prepared by electrostatic spinning. A spinning solution comprises the following components in percentages by weight: 55-70% of isopropanol, 10-20% of deionized water, 10-15% of poly(ethylene-co-vinyl alcohol), 3-10% of carbon fiber, 2-10% of nanometer zinc oxide, and 3-10% of negative ion nanopowder. The negative ion nanopowder comprises 10-100nm tourmaline, opal and magnesium oxide, and a weight ratio of tourmaline to opal to magnesium oxide is (3-10):1:1. Compared with the prior art, the inventive nonwoven fabric has good anti-bacterial and anti-ultraviolet effects, and can long-term release negative ions beneficial for human health, under the premise of maintaining good mechanical properties, and has wide application prospects in the field of water filtration treatment.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to an anion-filtering non-woven fabric. Background technique [0002] High-voltage electrospinning (electrostatic spinning), referred to as electrospinning, was proposed by the American Formhals in 1934 as a patent concept. At present, this method has been used in dozens of different polymers. It is an important method for preparing ultrafine fibers and non-woven fabrics that has only been adopted in recent years at home and abroad. Electrospinning machine consists of three main parts: spinneret and spinning solution supply system, fiber collecting plate and high voltage generator. The spinning solution is accelerated under the action of electrostatic force and does not break up to form fine flow clusters. After the solvent is volatilized or the melt is cooled, it condenses or solidifies into fibers, which are deposited on the collecting plate or collecting wheel in the form of non...
