Silver charcoal deodorizing antibiotic nonwoven fabric and preparation method thereof
Technical field
The invention belongs to the bondedfibre fabric technical field, be specifically related to a kind of silver-colored charcoal deodorizing antibiotic nonwoven fabric, and relate to the preparation method of this silver charcoal deodorizing antibiotic nonwoven fabric
Background technology
known antibacterial nonwoven cloth made is in as polyester fiber, polypropylene fibre and/or the natural fabric of main material such as cotton fiber, to add through the deodorizing antibiotic agent solution to soak and the iatric fiber of oven dry; Iatric fiber both can be aforesaid polyester fiber, polypropylene fibre and/or cotton fiber, also can be other similar fiber such as acid fiber by polylactic or the like.With one or more the fiber mixing (industry is claimed mixed cotton) in iatric fiber and other fiber such as the aforementioned fibers; And after opener shredding, carding machine combing, the lapping of lapping machine,, obtain the deodorizing antibiotic nonwoven fabric again through needing machine acupuncture or through spun-laced machine water thorn.This deodorizing antibiotic nonwoven fabric exists the deodorizing antibiotic effect to be difficult to lasting shortcoming, and for example, along with the increase of wash number, the deodorizing antibiotic effect fails gradually.And the expansion because the persistence of deodorizing antibiotic effect is short of to purposes constitutes restriction, for example is difficult to expand to get into bed dress product, medical and hygiene article, feminine hygiene articles, disposable sanitary articles and filtering material or the like.
antibiotic nonwoven material or title nonwoven fabric particularly have report in the Chinese patent document at document, for example CN1346905A (process for preparing Ag-carried antibacterial composite non-woven fabric), CN101302682A (the antibiotic superfine fibre nonwoven cloth production method of embedded with nano silvery) and CN1227292A (anti-bacterial water prick nonwoven cloth and production method thereof) or the like.The typical Nanometer Antibacterial Non-woven Cloth Filter And Preparation Method that provides like the antibacterial nonwoven cloth made of silver fiber and the CN1253615C of CN100535220C recommendation; The former is the silver-colored fiber that the surface of the 0.5-2% of interpolation total weight of fiber in nonwoven fabric is coated with silvering; Silver-colored fiber as other raw materials mix of one of raw material and nonwoven fabric, is finally processed antibacterial nonwoven cloth made of silver fiber; The latter is to be that polypropylene fibre of 91-88 part and the silver of 1-9 part are that antiseptic nano powder is processed by parts by weight, specifically is to be that the antiseptic nano powder mixing obtains base-material with polypropylene fibre particle and silver, and base-material obtains antibacterial nonwoven cloth made through melting and spraying.
aforementioned CN100535220C and the resulting nonwoven material of CN1253615C have the strong point of antibiotic and sterilizing; But, therefore do not have the effect of toxic and harmful in deodorizing, purification, filtration and the absorbed air etc. because main composition still is polyester fiber, polypropylene fibre and/or natural fabric as the nonwoven fabric raw material.
Improving constantly of
Along with people's health perception; The environment-friendly and green of the bedroom that is not limited to give an example the front being adorned articles for use, medical and hygiene article, maternity and child hygiene articles for use, disposable daily necessities and even automobile interior articles for use such as roof of the vehicle and carpet or the like requires harsh day by day; Therefore expect that present widely used nonwoven fabric except the strong point that possesses antibiotic and sterilizing, also has environment protectings such as aforesaid deodorizing, purification, filtration and absorption.
The applicant has carried out long-term and good try for this reason, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of not only to be had excellent antibiotic and sterilizing effect but also has both the silver-colored charcoal deodorizing antibiotic nonwoven fabric that desirable deodorizing, purification, filtration and absorption property are arranged.
another task of the present invention is to provide a kind of preparation method of silver-colored charcoal deodorizing antibiotic nonwoven fabric; This method technological requirement is harsh and can rely on conventional producing technology of non-woven fabrics and equipment to be achieved, and can ensure comprehensive embodiment of the antibiotic and sterilizing effect of nonwoven fabric.
task of the present invention is accomplished like this, a kind of silver-colored charcoal deodorizing antibiotic nonwoven fabric, and it is to be mixed and made into by active carbon fibre peacekeeping nano Ag antibacterial fiber.
in a concrete embodiment of the present invention, said NACF shared parts by weight in nonwoven fabric are 80-90 part, and the parts by weight that described nano Ag antibacterial fiber accounts in nonwoven fabric are 10-20 part.
Another task of the present invention is accomplished like this, a kind of preparation method of silver-colored charcoal deodorizing antibiotic nonwoven fabric, and this method may further comprise the steps:
A) preparation nano Ag antibacterial fiber is inserted viscose in the Nano silver solution earlier and is soaked into, and then dewater and dry, and the moisture content of control bake out temperature, control drying time and the control viscose after drying, obtain nano Ag antibacterial fiber;
B) shredding, with NACF by the opener shredding, and with nano Ag antibacterial fiber equally by the opener shredding, obtain the nano Ag antibacterial fiber of the active carbon fibre peacekeeping shredding of shredding;
C) mixed cotton is introduced the cotton blender machine mixing with 80-90 part NACF of shredding and 10-20 part nano Ag antibacterial fiber of shredding by weight, obtains silver-colored charcoal deodorizing and antibacterial fiber compound;
D) combing and lapping, elder generation by the carding machine combing, becomes web by lapping machine laying with silver-colored charcoal deodorizing and antibacterial fiber compound again;
E) thorn closes, and web is closed by needing machine or spun-laced machine thorn, obtains silver-colored charcoal deodorizing antibiotic nonwoven fabric.
in another concrete embodiment of the present invention, steps A) described in the concentration of Nano silver solution be 500-1000ppm.
in another concrete embodiment of the present invention, steps A) described in the particle diameter of Nano Silver be 5-20nm.
in another concrete embodiment of the present invention, steps A) described in time of infiltration be 10-30min.
also have among the concrete embodiment of the present invention; Steps A) the control bake out temperature described in is that bake out temperature is controlled to be 130-160 ℃; Described control drying time is that the time is controlled to be 10-30min, and the moisture content after the described control oven dry is that moisture content is controlled to be 8-14%.
more of the present invention and among concrete embodiment, steps A) described in the fiber number of viscose be 1.5-1.8dtex, the length of viscose is 35-40 ㎜.
technical scheme provided by the invention is owing to adopted mixing of NACF and nano Ag antibacterial fiber; Therefore resulting nonwoven fabric not only has good inhibition and bactericidal action to the bacterium that grows, mould etc.; And play by NACF and to embody feature of environmental protection green property such as the effect of the toxic and harmful of formaldehyde, benzene etc. in remarkable deodorizing, purification, transition and the absorbed air, make the purposes of the silver-colored charcoal deodorizing antibiotic nonwoven fabric that obtains be able to abundant expansion.
