Description
Technical field
The present invention relates to field of textiles more particularly to a kind of floride-free water repellent fabric and its manufacturing methods.
Background technique
Water repellent finish is that functions of textile fabrics arranges important one of project, most with extensive water repellent finishing agent be containing
The fluorochemical of 8 carbochains or 6 carbochains.Studies have shown that generated by-product-is complete in process of production for fluorochemical
Fluorine caprylate (PFOA) and perfluorooctane sulfonate (PFOS) have potential carcinogenicity, and are difficult the metabolism by biology
And decompose, it is one of the organic pollutant for being most difficult to degradation at present.2008, European Union formally implemented to order within a certain time, the spinning to outlet European Union
Fabric, PFOS content are necessarily less than 1ug/m2, also proposed same limitation to PFOA and require.Then, American market it is also proposed that
Corresponding limitation.Therefore, floride-free water repellent finish is by urgent need.
Traditional floride-free arrange can be divided into hydrocarbon and organic silicon, and conventional process, which uses, pads resin, bakes
Mode handle.Assign fabric certain water repellency after processing.
It is bigger than fluorochemical to the surface tension of water between floride-free water repellent, the water repellent effect of general treated fabric
Fruit is relatively relatively low；Preferable water repellent effect in order to obtain is usually taken and increases the mode of water repellent concentration and improve water repellent effect,
After the general common C8 or C6 water repellent dosage of amount ratio is higher by 2 times, but concentration dosage is promoted, roll banding, Boardy Feeling, fabric table are brought
The negative issue of colourless, affects the style and continuous production of final fabric, and due to the promotion of resin concentration and
The problems such as roll banding brought fabric surface fault rate increase, cost significantly promotes.
As the application for a patent for invention of Publication No. CN104878617A discloses a kind of production of floride-free waterproof shuttle-woven fabric
Method irradiates shuttle-woven fabric using the plasma beam that plasma generator emits, makes processed fabric surface
Concave-convex coarse structure is formed, then carries out padding floride-free finishing fluid on its roughened surface.By knitting for plasma resonance
Object, surface roughness can be formed " lotus leaf effect ", and the ability of fabric water repellent is enhanced.But the price of patent is expensive, meeting
The mechanical property for influencing fabric, reduces the service life of product.
For another example it is water-soluble to disclose a kind of modified manometer silicon dioxide for the application for a patent for invention of Publication No. CN102021819A
The super water repellent finishing agent of glue free-floride and its application, the preparation of finishing agent include: (1) by presoma, anionic surfactant and water
Mixing, is vigorously stirred at 20~50 DEG C；(2) catalyst ammonia water is slowly added dropwise, stirs, then add modifying agent chain alkyl silicon oxygen
Alkane continues to stir, and the modified SiO2 hydrosol is made.This method will affect the mechanical property and style of fabric, reduce making for product
Use the service life.
For another example the patent that notification number is CN102277721B discloses a kind of the whole of nano aluminium oxide floride-free super-hydrophobic fabric
Reason method, comprising: ammonium hydroxide is added at (1) 50~70 DEG C in the aluminum saline solution that mass percent concentration is 20~35% and adjusts
PH is 9.0~9.5, obtains white solid after suction filtration, washing, drying；After white solid is mixed with water, peptizing agent tune is added
Saving pH value is 3.5~4.5, flows back 3~5 hours at 75~90 DEG C or microwave heating flows back 20~60 minutes, obtain nanometer
Alumina sol；(2) long chain fatty acids or hard soap, water and alcohol are mixed, obtains water repellent；(3) fabric is being received
It pads or impregnates in rice alumina sol and water repellent, fabric preliminary drying, training after arrangement are dried to obtain the final product.There are cost mistakes for this method
Height is not easy the problems such as promoting.
Summary of the invention
To overcome roll banding existing in the prior art, Boardy Feeling, fabric surface albefaction, affect the style of final fabric with
And continuous production, and the increase of fabric surface fault rate brought by promotion as resin concentration and roll banding etc., cost
The problems such as significantly being promoted, the present invention provides a kind of manufacturing methods of floride-free water repellent fabric, including fabric refining, dyeing, water
Wash it is dry, pad resin treatment, drying, bake and press polish, it is described that pad resin liquid composition in resin treatment include 10-30g/L
