Abstract
The invention is a sol-gel dressed nonwoven fabrics for generating negative ions, a process for preparing same and an application thereof. A polyolefin, polyester, polyamide nonwoven fabric is performed with negative ion dressing by using a method for generating negative ions in air, using a sol-gel technic, and using a rolling-drying-baking process, and an application of an antimicrobial can be combined. The nonwoven fabric performed with sol-gel negative ion dressing can be used as a filtering material of a ventilation device in a room or a vehicle, increase the negative ions in the air, and reduce bacteria in the air, thereby effectively hold refreshing air in the room or the vehicle.
Description
Technical field:
The invention belongs to the light industry technical field, be specifically related to a kind of colloidal sol-gel dressed nonwoven fabrics, preparation method and its usage that produces anion, can be used to prepare the air-conditioning filter material that produces anion.
Background technology:
Along with the raising of people's living standard, also more and more higher to the air quality requirement of environment of living in, anion has good health-care function to human body, is referred to as airborne vitamin by many scientists.According to statistics, secondly the anion concentration in forest and waterfall district the highest (every cubic centimetre of content is 1000 to 5000) in the Nature is high mountain, seashore, residential area, city and indoor changes in temperature gas room content minimum (every cubic centimetre is 0 to 5).And the nonwoven fabric of collosol and gel arrangement can discharge every cubic centimetre in anion after tested up to 5000 to 6000.Filter material as air-conditioning in indoor or the car can increase anion in the air, in conjunction with the application of antiseptic, can reach the effect that improves air quality.And compare with the Electronic Negative ion generator, this technology has no energy consumption, can not produce advantages such as ozone.Simultaneously can overcome (application number 02137429) in the anion powder arrangement process, the difficult dispersion, the easy shortcoming of reuniting, advantage such as it is simple to have technology, easy to operate.
