Abstract
The invention provides a super-durable and super-hydrophobic textile and its making method. The method comprises the following steps: carrying out alkaline treatment of a terylene fabric to make the surfaces of micro-sized fibers have a nanometer rough structure and make the fabric have a micro-nano structure rough surface, and carrying out low surface energy treatment of the fabric by a mixed solution comprising long-chain alkyl silane and a polydimethylsiloxane compound to obtain the super-durable and super-hydrophobic textile. The static contact angle of water drops on the surface of the terylene fabric prepared in the invention is greater than 150DEG, the water drops can easily roll on the surface of the fabric, and the textile still has an excellent super-hydrophobic performance after strong friction, long-time washing, and long-time immersion in a strong acid, a strong alkali and a strong electrolyte solution.
Description
[technical field]
The present invention relates to a kind of preparation method of function textile, particularly a kind of super durable super-hydrophobic textile and preparation method thereof.
[background technology]
Super-hydrophobic textile has special wettability, and namely water droplet, and is easy on its surface to roll greater than 150 ° at the contact angle of fabric face.The dirt that water droplet can speckle with the surface in rolling process is together taken away, and Here it is so-called " lotus leaf self_cleaning effect ".Ultra-hydrophobicity is so that Realization of Product " wet behind the rain, at any time folding and unfolding " prolongs the service life of fabric thereby also avoided water that the dipping degraded of fibre substrate is worn out simultaneously.Super-hydrophobic textile has in industrial production, medical treatment, military use product and daily life and is widely used.
The key technology of preparation super hydrophobic surface has 2 points: (1) namely improves the roughness on surface at surface construction micro-nano coarse structure; (2) then it being carried out low-surface-energy processes.The method of at present, constructing the micro-nano coarse structure at fabric face mainly contains: sol-gel process (Chinese patent CN 102277720A), nano particle method for constructing (Chinese patent CN102321974A), fiber surface growth in situ nanostructured method (Chinese patent CN101748596A) etc.More than construct the micro-nano coarse structure at fabric face method all be to introduce other material of non-fiber bodies at fiber.These materials mostly number are inorganic nanoparticles, yet owing to adhesion weak between nano particle and the fibre substrate, so that the fabric of above-mentioned preparation is easy to be subject to mechanical force such as finger presses, the impacts such as washing and mechanical friction, thereby cause fabric in use at ordinary times, to lose easily super-hydrophobicity, so the persistence of ultra-hydrophobicity is bad.
[summary of the invention]
Technical problem solved by the invention provides a kind of super durable super-hydrophobic Polyester Textiles and preparation method thereof that has, and to improve added value and the practicality of textiles, expands its range of application.
For achieving the above object, the invention provides a kind of preparation method of super-hydrophobic Polyester Textiles, at first at high temperature process dacron with highly basic, fiber surface is etched, the surface produces rough hole, to improve the roughness of fiber surface, then adopt the mixed solution of long chain alkyl silane and dimethyl silicone polymer compound to process dacron.
Described step with the alkali treatment dacron is: at first dacron is washed with deionized water, after the oven dry, put into the NaOH that concentration is 400-450g/L, promoter 1227 concentration are to flood in the dressing liquid of 0.5-4g/L, then take out fabric and put into steam and carry out decatize, fully wash, dry with deionized water at last.
Described long chain alkyl silane is long chain alkyl silane or fluoroalkyl silanes, chain alkyl siloxanes or fluoroalkylsiloxane, chain alkyl chlorosilane or fluoro-alkyl chlorosilane and their mixture of carbon number 6 ~ 18.
Described dimethyl silicone polymer compound is for getting the dimethyl silicone polymer solvent in SYLGARD 184 products and elastomer silicone curing agent component take the even mixing of ratio of mass ratio as 8: 1 ~ 10: 1.
The step that described mixed solution with long chain alkyl silane and dimethyl silicone polymer compound is processed dacron is: dacron is impregnated in the mixed solution of long chain alkyl silane and dimethyl silicone polymer compound, then use padding machine to roll unnecessary dressing liquid, at 80 ℃ of lower 3min that process, then take out fabric, at 135 ℃ of lower baking 0.5h.
According to the super durable super-hydrophobic textile that the inventive method makes, the contact angle of itself and water droplet is 150.3 ° ~ 162.1 °.
By the super-hydrophobic Polyester Textiles of processing method of the present invention preparation, with the static contact angle of water droplet greater than 150 °.The present invention utilizes the micron order coarse structure of fiber own, use the alkaline etching dacron, make the micron order fiber surface be produced rough hole by alkaline etching, form the nanoscale roughness at fiber surface, thereby make formation of fabrics micro-nano structure rough surface, improving the ultra-hydrophobicity of fabric face, and do not need to introduce other nano-particle material.Dacron after the alkali treatment, a large amount of carboxyls and hydroxyl are contained in its surface, also help low-surface-energy material and fiber surface and form chemical bonds.Make the ultra-hydrophobicity antifriction of the super-hydrophobic Polyester Textiles of preparation, washable, chemically-resistant solution corrosion.The pattern of the fiber surface of dacron and alkali treatment dacron, and the superhydrophobic fabric of preparation surface water droplet form is as shown in drawings.
