Description

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 to add through the deodorizing antibiotic agent solution to soak and the iatric fiber of oven dry in as polyester fiber, polypropylene fibre and/or the natural fabric of main material such as cotton fiber, 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 iatric fiber and other fiber mixed with fibers (industry claims mixed cotton) of one or more in the fiber as described above, 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 claim that nonwoven fabric is at document particularly existing report, for example CN1346905A(process for preparing Ag-carried antibacterial composite non-woven fabric in the Chinese patent literature), the antibiotic superfine fibre nonwoven cloth production method of CN101302682A(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 as 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 is mixed as other raw material of one of raw material and nonwoven fabric, finally make 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 made 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.
The resulting nonwoven material of aforementioned CN100535220C and CN1253615C has 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 a natural fabric as the nonwoven fabric raw material.
Along with improving constantly of health of people consciousness, the environment-friendly and green of the bedroom that is not limited to exemplify previously 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 technical scheme described below produces under this background.
Summary of the invention
