The preparation method comprises the following steps of: roughening the surface of dacron fiber by using an aminolysis and/or alkaline hydrolysis treatment process; and then, applying nano powder and a water and oil repelled finishing agent, which are subjected to a post-finishing method, to a textile, so that the rough structure of the fiber surface reaches a nano level and the dacron textile is endowed with water-repelling and oil-resisting performances. The prepared bionic super-hydrophobic antifouling dacron textile can be widely applied to top-grade clothing shell fabrics, home decorations and the like, and has a wide market application prospect.
Description
Technical field
The present invention relates to a kind of preparation method's of function dacron, particularly a kind of bionic super-hydrophobic antifouling dacron textile preparation method.
Background technology
Along with social progress, the variation of consumption concept, " back to nature " becomes the theme that people pursue gradually.Thinking based on bionical, obtains inspiration from special construction and the performance of organism, designs and prepares bionical textiles, and making it produce astonishing, fresh and new function has become one of important content of modern textile research.
Lotus leaf blade face presents extremely strong WATER REPELLENCY, and the water being sprinkled upon on blade face can be gathered into the globule automatically, and the rolling of the globule rolls out ，Shi blade face, blade face and remains totally dropping on sticky suction of dust mud on blade face, Here it is famous " lotus leaf effect ".
" lotus leaf effect " can break through conventional water-proof material development thinking in theory, and the roughness that the surface that reduces material can and be produced to microstructure combine, and makes material surface have the good water anti-pollution function of refusing.Utilize " lotus leaf effect ", exploitation bionic super-hydrophobic antifouling fabric meets consumers in general's demand.
In view of this, the inventor, in conjunction with being engaged in dacron area research work experience for many years, studies for a long period of time to above-mentioned technology enlightenment, and this case produces thus.
Summary of the invention
The preparation method who the object of this invention is to provide a kind of bionic super-hydrophobic antifouling dacron textile, method is simple, with low cost, has and preferably refuses water, antifouling property.
To achieve these goals, technical scheme of the present invention is as follows:
A preparation method for bionic super-hydrophobic antifouling dacron textile, comprises the following steps: (1), by aminolysis and/or alkaline hydrolysis treatment process, makes polyester fabric fibers surface roughening; (2) utilize postfinishing process that nano-powder and water-repellent oil-repellent agent are applied in above-mentioned fabrics, make fabric fibre surface roughness reach nano-scale.
Further, described aminolysis and/or alkaline hydrolysis treatment process prescription are: amine agent consumption 5-15g/L, alkaline agent consumption 4-10 g/L, bath raio 1:50; Process conditions are: dacron is processed to 20-40 minute at 70-90 ℃ in the treatment fluid of the agent of 5-15g/L amine and/or 4-10 g/L alkaline agent, bath raio 1:50, and clear water is cleaned.Thereby process costs is cheaper, and make dacron surface roughening, be easier to subsequent technique and arrange.
Further, in described aminolysis and/or alkaline hydrolysis treatment process, amine agent used is methylamine or ethylenediamine, and alkaline agent used is NaOH.Thereby process costs is cheaper, and make dacron surface roughening, be easier to subsequent technique and arrange.
Further, in described aminolysis and/or alkaline hydrolysis treatment process, fabric process conditions in the treatment fluid of bath raio 1:50 are at 80 ℃, to process 30 minutes.Thereby process costs is cheaper, and make dacron surface roughening, be easier to subsequent technique and arrange.
Further, in described aminolysis and/or alkaline hydrolysis treatment process, also comprise the step that the dacron after clear water is cleaned is dried.Thereby process costs is cheaper, and make dacron surface roughening, be easier to subsequent technique and arrange.
Further, described postfinishing process prescription is: Organic fluoride finishing agent 15-40g/L, silane coupler 2-4g/L, nano-powder 5-10g/L; Technological process and process conditions are: padding finishing liquid (pick-up 70%-80%) → oven dry (70-90 ℃, 2-8 minute) → bake (170-180 ℃, 2-4 minute).Thereby make process costs cheaper, and make dacron surface roughness reach nano-scale, roughening degree is better, and has and preferably refuse water, antifouling property.
Further, silane coupler used is silane coupler KH-B92, Silane coupling reagent KH-570 or silane resin acceptor kh-550.Thereby make process costs cheaper, and refuse water, anti-fouling effect is better.
Further, nano-powder used is nano titanium oxide, nano silicon or nano zine oxide.Thereby make process costs cheaper, and make dacron surface roughness reach nano-scale, roughening degree is better, and has and preferably refuse water, antifouling property.
