Description
Technical field
The present invention relates to field of textiles, specifically, relate to the non-weaving cloth that a kind of air humidifying and purifying is used.
Background technology
The quality of air quality is the problem that people generally are concerned about, because people are indoor the mosts of the time, so the hazard ratio outdoor air that room air pollution is brought pollutes even more serious.In developed countries such as America and Europe and Japan, the application of indoor air-purification device is very general.In China, atmosphere pollution, indoor decoration pollution etc. make people also more and more pay attention to air pollution problems inherent, and various indoor air purification treatment products arise at the historic moment, and the manufacturing enterprise of many these series products occurred.Through ten years development, formed an emerging industry-----indoor environment purification treatment industry now.Data shows that just with the speed increment in every year nearly 30%, annual production has reached nearly ten million platform to the product sales of this industry in China.
Because the dry environment in the north, the user hopes when purifying, humidification function to be arranged, and therefore, the pure type humidifier with humidification function arises at the historic moment.Purification and humidification have various forms; One of them be with the special paper products with antibiotic, absorbent function as purify, absorbent material; Make the paper products of air penetration immersion,, reach pure and fresh, the moistening purpose of outlet air inlet air filtration, sterilization, humidification.This kind filters humidification method, and humidification is effective, does not stay the incrustation scale vestige on the furniture, and airborne trifle in the world is removed efficiently simultaneously, be the pattern that relevant producer widelys popularize therefore, but paper products has some shortcomings always: paper products material anti-microbial property is difficult for keeping; Easy scale formation above the material after use a period of time, water absorbing properties descends; Paper products brute force under hygrometric state is low etc.
Patent application 200410053952.6 discloses the hydro-entangled non-woven fabric filtering material that a kind of gas, liquid filtering are used; This hydro-entangled non-woven fabric filtering material includes spunlace non-woven layer of cloth and sizing material; Sizing material and spunlace non-woven layer of cloth combine; Sizing material is coated in the surface of spunlace non-woven layer of cloth, and sizing material also can be immersed in mutually with the spunlace non-woven layer of cloth.The preparation method of this hydro-entangled non-woven fabric filtering material is the spunlace non-woven layer of cloth to be put into glue application device carry out the gluing processing; Be the applicator roll of 1～10kg then through pressure; Dry processing again, bake out temperature is 100～180 ℃, processes the hydro-entangled non-woven fabric filtering material.Yet the phenolic resins that this sizing material adopts has toxic action to human body, is difficult to this nonwoven fabric filter material is applied to the air humidifying and purifying of living environment.
Patent application 200810012311.4 discloses a kind of preparation method of antimicrobial modified polyvinyl alcohol nonwoven compound microporous filtering film, and it comprises the steps: to prepare the casting solution of pyridine modified polyvinylalcohol, crosslinking agent, catalyst composition, standing and defoaming; Remove by filter insoluble matter, under suction function, be coated on the pretreated fusion-jetting polypropylene non-weaving cloth heat treatment; Dry; Clean to neutral, quaternized processing, diaphragm soaks for use in pure water.Yet the made material of this method is a kind of micro-pore-film filtration material, is mainly used in liquid filtering, and especially water treatment is not suitable for the air wetting material.
Patent application 96118922.3 discloses a kind of big flow filter dirt disinfection filtering film and manufacturing approach thereof; This filter membrane immerses treatment fluid by the mixed nonwoven fabric of copying of natural plant fibre, vinylon, self-stickness fibre nonwoven fabric or natural plant fibre and polyvinyl acetal fiber, self-stickness fibre as base material, and wherein wt umber proportioning is polyol 8-20, or/and Sodium Polyacrylate 10-30; Glycerine 20-120; C12-C18 alkane methylbenzyl ammonium halide 0.05-3, water 800-4000, peppermint 0-3; Dip time 0.5-2 hour, and under 20-60 ℃ of temperature dry 1-4 hour.The major function of the filter membrane that this method is processed is the adsorption capacity that strengthens air dust, purifies thereby can be used for mass flow air, but because it does not possess enough suction ranges, therefore is not suitable for air humidifying and purifying.
In view of this, special proposition the present invention.
Summary of the invention
The present invention's first purpose is to provide a kind of air humidifying and purifying to use non-weaving cloth, and described air humidifying and purifying is good with non-weaving cloth intensity, long service life, and the suction bacteria-eliminating efficacy is good.
The present invention's second purpose is to provide the preparation method of a kind of foregoing air humidifying and purifying with non-weaving cloth, and described preparation method is easy and simple to handle, is convenient to suitability for industrialized production.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of air humidifying and purifying is used non-weaving cloth, and it is 100～200mm that said air humidifying and purifying uses the non-weaving cloth suction range, and wet tensile (strength) is 3.0～10.0KN/m; Being preferably suction range is 120～180mm, and wet tensile (strength) is 5.0～9.0KN/m; More preferably being preferably suction range is 130～160mm, and wet tensile (strength) is 5.5～8.0KN/m.
