As an optimization：(1) fleece fabrics is through in dioxygen water pretreatment：By pending fleece fabrics under loose formula state By bath raio 1：15, in the sodium carbonate liquor of the antistatic agent SN, 0.3-0.5g/L of 0.3-0.5g/L, 40 DEG C of constant temperature are soaped Then 20min is washed, use 30%H2O2For 20-40mL/L, hydrogen peroxide bleaching stabilizer 0.5-1g/L, penetrating agent JFC 0.5-1g/L, 60 DEG C of processing 40min, washing are removed water, are dried.
As an optimization：In (2) the fleece fabrics plasma etching industrial：Using AtomfloTM250 type atmospheric plasmas Body jet apparatus, ejection form plasma jet and are modified fleece fabrics, and fleece fabrics is laid in apparatus for processing plasma On bottom crown, atmospheric pressure plasma jet treatment condition is as follows：Medium argon gas, power parameter 200V, output power 6-100KW, processing Time 20s.
As an optimization：The porous antibacterial film of (4) polystyrene-b- polyacrylic acid is crosslinked in composite modified cashmere：By 5- 8g/L polystyrene-b- polyacrylic acid porous antibacterial matrix, 0.5-1g/L berberines, 0.3-0.5g nano-ZnOs, 0.3-0.5g 3- trimethoxies silicon substrate-propyl-dimethyl octadecyl ammonium chloride antiseptic, 0.8-1.2g 3- aminopropyl triethoxysilanes, The Goon1201 amido silicon oils of 0.4-0.8g/L are dissolved in chloroform, and plasma pretreatment cashmere is immersed above arrange Liquid, two leachings two roll, liquid carrying rate 50-60,80 DEG C dry, form porous antibacterial film in wool surfaces, obtain finished product.
Advantageous effect：The specific advantage of the present invention is as follows：
(1) in the present invention, using plasma pre-processes cashmere fiber, after assigning the extraordinary etching effect of cashmere, with 3- aminopropyl triethoxysilanes coupling agent, by bridge formation base to cashmere surface, is prepared for reactive cashmere fiber as crosslinking agent, Porous antibacterial matrix, berberine, ZnO, cationic antibacterial agent, part amido silicon oil are added in finishing agent, forms plasma- The porous antibacterial film antibacterial process of polystyrene-b- polyacrylic acid.It is crosslinked by the porous antibacterial film of polystyrene-b- polyacrylic acid Wool fabric, clump count are greatly decreased compared with control sample, have reached 96.6% to the bacteriostasis rate of Escherichia coli, obtain good anti- Bacterium property.
(2) in the present invention, extraordinary finishing agent adsorption effect can be obtained in cashmere after Low Temperature Plasma Treating, is work Industry provides fabulous pre-treatment effect, is organically incorporated antiseptic by the coupled action of 3- aminopropyl triethoxysilanes In cashmere fiber so that fiber strength is also partly promoted, fleece fabrics antibacterial, keeps fabric smooth.
(3) in the present invention, fleece fabrics improves cashmere fiber wettability under loose formula state through dioxygen water pretreatment, soft Change cashmere fiber surface scale layer structure, be conducive to rear road plasma etching, improves etching effect.
(4) in the present invention, pretreatment is performed etching to cashmere fiber using low temperature plasma, surface scale is destroyed, prevents Only cashmere felting makes fiber surface generate segment polarity group, increases cashmere surface hydrophilicity and reactivity, while not losing Cashmere fiber strength.
