Background technology
Antibiotic fabric be on fabric in conjunction with organic or inorganic antibacterial material, mainly can directly adopt anti-bacterial fibre to make each kind fabric, perhaps fabric is utilized antiseptic to carry out post processing processing to obtain anti-microbial property.Both in comparison, the former antibacterial effect is lasting, water-wash resistance is good, but the production of anti-bacterial fibre is comparatively difficult, to having relatively high expectations of antiseptic, and latter's processed is comparatively simple, washability and antibacterial effect are relatively poor.Present for want of good anti-bacterial fibre is so in various antibiotic fabrics on the market, still processing person is in the majority later on.
Except processing mode influences antibacterial effect, the more direct antiseptic that depends on of antibacterial effect.Antiseptic generally can generally be divided into the organic or inorganic antiseptic, and wherein inorganic antiseptic is applied to the antibacterial treatment of fabric in recent years gradually because of long-acting and to advantages such as the skin low irritant are low.
Prior art mainly is applied in inorganic antiseptic on the fabric in following several modes.A kind of mode is for example to utilize inorganic matter, pottery or have the ion exchangeable clay, as the silver ion carrier.Correlation technique can be with reference to No. the 6th, 514,622, United States Patent (USP) case notification number, United States Patent (USP) case notification number the 6th, 495, No. 367, United States Patent (USP) case notification number the 6th, 476, No. 095, United States Patent (USP) case notification number the 6th, 461, No. 386, United States Patent (USP) case notification number the 6th, 361, No. 567 and United States Patent (USP) case notification number the 6th, 288, No. 076, and above-mentioned patent is all classified list of references of the present invention as.
Another kind of mode then utilize macromolecule for example glue or water soluble polymer as the silver ion carrier.Correlation technique can be with reference to United States Patent (USP) case notification number the 6th, 495, No. 367, United States Patent (USP) case notification number the 6th, 238, No. 686, United States Patent (USP) case notification number the 6th, 294, No. 186, United States Patent (USP) case notification number the 6th, 264, No. 936 and United States Patent (USP) case notification number the 6th, 224, No. 898, and above-mentioned patent is also classified list of references of the present invention as.
Perhaps, can utilize the means of plating to plate antibacterial metal at material surface.Correlation technique can be with reference to No. the 6th, 267,782, No. the 6th, 451,003, United States Patent (USP) case notification number and United States Patent (USP) case notification number, and above-mentioned patent is with classifying list of references of the present invention as.
In addition, also can utilize the means of physical vapour deposition (PVD) to make the metal ultra-fine grain, to increase the dissolution rate of metal ion.Correlation technique can be with reference to No. the 5th, 985,308, No. the 6th, 333,093, United States Patent (USP) case notification number, No. the 6th, 017,553, United States Patent (USP) case notification number and United States Patent (USP) case notification number, and above-mentioned patent one is listed as list of references of the present invention.
In a word, above-mentioned prior art is not taken off in the means by various carriers, plating or physical vapour deposition (PVD) inorganic antiseptic is applied on the fabric, with problems such as the rate of release of improving inorganic antibacterial material and dissolution rates.Yet still there is following shortcoming in above-mentioned prior art.At first, with inorganic matter, pottery or have the ion exchangeable clay as the silver ion carrier, the rate of release of silver ion is lower and release time is of short duration.For above-mentioned carrier granular is disperseed in material, still need and use interfacial agent or other colloid dispersion technology, and the complexity of the process of raising.And mix and the dispersion of carrier are to belong to the leading portion process, can directly improve the difficulty of back segment process processing.
Secondly, as the silver ion carrier, be difficult for the accurately rate of release of control silver ion with macromolecule.In addition, glue or water soluble polymer might produce cytotoxicity, and polymeric additive also can harmful to human if ooze out.
Moreover, when using the means of electroplating to plate antibacterial metal, may contain harmful substance in the electroplate liquid.Add that the antibacterial metal consumption is high than other means when electroplating, but significantly do not promote antibacterial effect, cause the waste of antibacterial metal material.And, because the size of the metal coating that electroplate to form is greatly at 1 micron, easy stress or friction when the antibiotic fabric of wear electroplating processes and come off.
In addition, when utilizing the means manufacturing ultra-fine grain of physical vapour deposition (PVD), gas, pressure and the temperature etc. that need restriction to feed make the unlikely alligatoring of metal ultra-fine grain.The metal ultra-fine grain of Xing Chenging not only has the shortcoming of densely distributed and skewness because of the restriction of process thus, makes that cost is difficult for reducing, and the metal ultra-fine grain that forms easily surpasses the requirement of general clothing with antiseptic.Secondly, oppose at general suction, the good fabric of hydrophily, need expend the operation that the long period vacuumizes, with the moisture of certain removal fibrous inside because physical vapour deposition (PVD) must be finished drilling in vacuum environment.Moreover, with regard to existing equipment, and unfavorablely be plated metal ultra-fine grain on the single thread, and the design of revising or changing vacuum cavity at making anti-bacterial fibre, required cost is also high.Again, the antibiotic fabric of formation is not water-fast to be washed, rubs or bending, says nothing of in a large number and produces.
Because the bactericidal effect of silver coating fabric after suction is preferable, therefore, be necessary to provide a kind of manufacture method of long-active antibacterial fiber in fact, to overcome all weakness of above-mentioned existing process.
