5, dyeing: adopt existing technique to dye to fabric.
The antibiotic facing material of silver-colored mesopore silicon oxide antiseptic is carried in the set that adopts the present invention to prepare, its structure as shown in Figure 1, on fabric 1, set has the silver-colored mesopore silicon oxide antiseptic layer 2 of carrying, and the mesoporous aperture of carrying silver-colored mesopore silicon oxide antiseptic layer 2 is 6.4-20nm, and specific area is 500-800cm2/ g, pore wall thickness 3.4-6.2nm, the percentage that simple substance silver in described year silver-colored mesopore silicon oxide antiseptic layer 2 accounts for year silver-colored mesopore silicon oxide antiseptic layer 2 gross mass is 5-10%, carries a silver-colored mesopore silicon oxide antiseptic layer 2 and is discrete particulate form, and the particle size of each particle is 600-700nm.
Alternative embodiment 2: the impact of the dispersant of variety classes and concentration on antiseptic particle diameter.
Production method is with embodiment 1, and difference is to adjust kind and the concentration of different dispersants, and adds up its impact on antiseptic particle diameter.
Find through test: the kind of dispersant and concentration can affect the dispersion effect of antiseptic, and the particle diameter after antiseptic is dispersed is less, and particle suspends more even in solution, and sinking speed is slower, and the effect of dispersant is better, anchor at antiseptic on fabric more even. Mensuration adds the particle size of the antiseptic after the dispersant of variety classes and concentration to judge the effect of dispersant, as shown in table 1:
The particle size of the antiseptic after the dispersant of table 1, variety classes and concentration
Because particle size error is larger, therefore data acquisition mean value and round are known according to table 1: dispersant is preferably Sodium Polyacrylate, effect is best.
Further the Sodium Polyacrylate dispersant of test variable concentrations is as shown in table 2 on the impact of antiseptic particle diameter:
Table 2,
| Concentration | 130 | 140 | 150 | 170 | 180 | 190 |
| Sodium Polyacrylate | 700nm | 650nm | 600nm | 700nm | 800nm | 850nm |
As shown in table 2, Sodium Polyacrylate dispersant concentration is 130-170mg/L, and effect is best.
Alternative embodiment 3: the impact of the adhesive of variety classes and concentration on adhesion efficiency and antiseptic particle diameter.
Production method is with embodiment 1, and difference is to adjust kind and the concentration of different adhesives, and adds up its impact on adhesion efficiency, antiseptic particle diameter.
Find through test: the kind of adhesive and concentration can affect antiseptic and anchor at the effect on fabric, and the effect of adhesive is better, anchor at antiseptic on fabric approximately many. The adhesion efficiency of surveying adhesive by calcining weight method, the fabric sample having by set is calcined and is removed organic principle in Muffle furnace, takes residual residue quality and calculates adhesion efficiency by formula:
Antiseptic quality * 100% in residue quality/antibiotic finishing solution after adhesion efficiency=calcining.
Select respectively UDT, KG-101, polyurethane, TYS adhesive, test and add up the adhesion efficiency that different adhesive kinds and concentration brings as shown in table 3 below:
The adhesion efficiency of table 3, different adhesive kind and concentration
As shown in table 1: when adhesive is selected TYS adhesive, its adhesion efficiency is the highest, and polyurethane, UDT take second place, therefore the preferred TYS adhesive of adhesive.
Further the TYS adhesive of test variable concentrations is as shown in table 4 on the impact of antiseptic particle diameter:
Table 4,
| Concentration | 32 | 34 | 36 | 38 |
| TYS | 72 | 70 | 70 | 68 |
As shown in table 4: TYS adhesive preferred concentration is 30-36g/L, and adhesion efficiency is for the highest.
Alternative embodiment 4: the impact of antiseptic concentration on anti-microbial property.
Production method is with embodiment 1, and difference is to adjust different antiseptic concentration, and adds up its impact on anti-microbial property.
For antiseptic, choose after the dispersant and adhesive in dressing liquid, the concentration of antiseptic can affect the antibacterial effect of fabric and wash the anti-microbial property after 50, and antiseptic consumption is very few, and fabric can not reach good antibacterial effect; Otherwise antiseptic consumption is too much, can cause again the waste of raw material. The present embodiment fabric sample detects sample to colibacillary antibiotic rate after arranging by the antibacterial antiplaque agent of variable concentrations, and result is as shown in table 5 below:
The antiseptic of table 5, variable concentrations is to colibacillary antibiotic rate
As shown in table 5: along with the raising of antiseptic consumption, antibiotic rate has obvious lifting, when antiseptic concentration reaches 150mg/L, now antibiotic facing material is after 50 washings, antibiotic rate still can remain on more than 98%, illustrates that antiseptic set on fabric is good, has excellent washability and persistence. Along with the further raising of antiseptic consumption, effect promoting is also not obvious, causes the waste of raw material and the rising of cost, and therefore, preferred antimicrobial agents concentration is 150mg/L.
Alternative embodiment 5:
Production method is with embodiment 1, difference is: cause variable color because silver and airborne material react, therefore for the fabric after making to arrange can be for light-coloured prods, also fabric is carried out to anti-variable color PROCESS FOR TREATMENT step (5) is front, anti-variable color technique can adopt existing technique.
Although the present invention is described by reference to preferred embodiment,, those of ordinary skill in the art should understand, and can be not limited to the description of above-described embodiment, in the scope of claims, can make the various variations in form and details.
