Description

Fabric with fire-retardant and antibacterial functions and preparation method thereof
Technical field
The present invention relates to a kind of fabric and preparation method, especially a kind of fabric with fire-retardant and antibacterial functions and its system Preparation Method.
Background technology
Textile fabric is widely used in daily life, and such as various baftas, linen, chemical fibre are knitted Thing, and their blend fabric etc..These textile materials easily burn, and rate of flame propagation is fast, be difficult extinguishing, while The dense smoke produced in combustion process also causes safely huge threat to natural environment and human life;Additionally, the fibre in fabric The plain strand of dimension contains substantial amounts of hydroxyl, thus hygroscopicity is very strong, and the growth for antibacterial provides good living environment, is grown Raw antibacterial not only can threaten to human health, can also pass through the structure that release acidic materials destroy cellulose, cause fine Dimensional fabric is degraded.Therefore, the fire-retardant and antibacterial of fabric is aroused widespread concern, and such as Chinese invention patent application is announced and said The bright A of book CN 101654864 were in a kind of fire-retardant polypropylene non-woven fabric and preparation method thereof disclosed in 24 days 2 months in 2010.The public affairs The product referred in cloth description is based on polypropylene non-woven fabric, the flame-retardant layer formed by fire retardant to be covered on its surface, Wherein, fire retardant is inorganic phosphorus type flame retardant, or organophosphorous fire retardant, or nitrogenous flame ratardant, or expansion type flame retardant;Preparation side Method is first polypropylene non-woven to be arranged in into 5~30min of dipping in the fire retardant aqueous solution that concentration is 10~40%, then by it 40 Winding, packaging after drying at~65 DEG C.Though this non-woven fabrics have fire-retardant performance, but also there is weak point, first, structure Fire retardant into flame-retardant layer is single component, and the flame retardant effect to be played is limited, it is difficult to obtain significant fire-retardant Effect;Secondly, only flame retardant efficiency, and without antibacterial functions;Again, preparation method can not obtain existing notable flame retardant effect and There is the product of antibacterial functions.
The content of the invention
The technical problem to be solved in the present invention is to overcome weak point of the prior art, there is provided it is a kind of it is fire-retardant significantly and Be provided simultaneously with antibacterial with fire-retardant and antibacterial functions fabrics.
The invention solves the problems that another technical problem be to provide a kind of above-mentioned with fire-retardant and antibacterial functions fabrics Preparation method.
For solve the present invention technical problem, the technical scheme for being adopted for:With fire-retardant and antibacterial functions fabric bags Fabric is included, particularly,
More than one layer of stain layer, polyphosphoric acid of the stain layer by poly (hexamethylene) stain and thereon are covered with the fabric Salting is constituted.
As with fire-retardant and the fabric of antibacterial functions further improvement:
Preferably, fabric is cotton fabric, or hemp fabric, or science fabric, or cotton fibriia blending is knitted Thing, or cotton fiber and chemical fibre blend fabric, or flaxen fiber and chemical fibre blend fabric, or non-woven fabrics.
Preferably, poly (hexamethylene) is polyhexamethylene guanidine phosphate, poly (hexamethylene) hydrochloride, poly- six methylene One or more mixture in base biguanide phosphate.
Preferably, Quadrafos are one or two mixture in polyphosphate sodium, APP.
For solve the present invention another technical problem, another technical scheme for being adopted for:It is above-mentioned with fire-retardant and The preparation method of the fabric of antibacterial functions includes infusion process, particularly completes step as follows:
Step 1, poly (hexamethylene) and Quadrafos is separately added in deionized water and stirs at least 1h, obtains 0.05 The poly (hexamethylene) aqueous solution of~5g/100g and the Quadrafos aqueous solution of 0.05~5g/100g;
Step 2, fabric is first immersed in poly (hexamethylene) aqueous solution and is taken out after 10~120s, with distilled water flushing 20 20~60min is dried at 50~80 DEG C are placed in after~120s, obtaining stain thereon has the fabric of poly (hexamethylene) stain, then will thereon Stain has in the fabric immersion Quadrafos aqueous solution of poly (hexamethylene) stain takes out after 10~120s, with distilled water flushing 20~ 20~60min is dried at 50~80 DEG C are placed in after 120s, obtaining thereon stain successively has poly (hexamethylene) stain and polyphosphoric acid salting Fabric;
Step 3, to thereon successively stain has the process of the fabric repeat step 2 of poly (hexamethylene) stain and polyphosphoric acid salting More than 0 time, the fabric with fire-retardant and antibacterial functions is obtained.
As the further improvement with fire-retardant and the fabric of antibacterial functions preparation method:
Preferably, fabric is cotton fabric, or hemp fabric, or science fabric, or cotton fibriia blending is knitted Thing, or cotton fiber and chemical fibre blend fabric, or flaxen fiber and chemical fibre blend fabric, or non-woven fabrics.
Preferably, poly (hexamethylene) is polyhexamethylene guanidine phosphate, poly (hexamethylene) hydrochloride, poly- six methylene One or more mixture in base biguanide phosphate.
Preferably, Quadrafos are one or two mixture in polyphosphate sodium, APP.
Preferably, it is 1~3h poly (hexamethylene) or Quadrafos to be added into the time stirred in deionized water.
Preferably, to thereon successively stain has the mistake of the fabric repeat step 2 of poly (hexamethylene) stain and polyphosphoric acid salting Journey is 1~30 time.
It is relative to the beneficial effect of prior art:
First, after using such structure, both because poly (hexamethylene) is imparted and knitted with the combination next to the skin of fabric The excellent anti-microbial property of thing, but because poly (hexamethylene) in burning when source of the gas and part acid source effect give full play to, with There are Quadrafos, the fabric synergism of carbon source effect that acid source is acted on during burning, and make after purpose product burning in microcosmic On generate substantial amounts of expanding bubble, and form heat-insulated foamed char.It is this by source of the gas and part acid source (polyhexamethylene guanidine Salt), the complete Intumescent Retardant System that collectively forms of acid source (Quadrafos) and carbon source (fabric), drastically increase purpose product The fire resistance of thing, even if purpose product is not only provided with excellent anti-microbial property, is also provided with efficient expandable flame retardant performance. Jing is surveyed, and the fire resistance of purpose product is far above prior art.
Second, the present invention is except the hydroxyl or carboxylic group that are sufficiently used poly (hexamethylene) and fabric fibre surface The interaction of hydrogen bond for existing, and ensure that outside firm combination between the two, also make existing cation polyhexamethylene Guanidinesalt stain layer is more securely joined with by electrostatic interaction with the anionic polymer Quadrafos of follow-up dipping, becomes three The one of extremely difficult segmentation, so that the stain layer of composition purpose product is provided with fabulous durability and service life.
Third, preparation method is simple, science, effectively.Purpose that is fire-retardant notable and being provided simultaneously with antibacterial has not only been obtained to produce Thing --- with fire-retardant and antibacterial functions fabrics, significant flame retardant effect and excellent antibacterial functions are also made it have, with And long-lived quality, more there is preparation process simple, low cost, environment friendly and pollution-free, applied widely and suitable extensive The characteristics of industrialized production, and then make purpose product that there is extraordinary commercial applications prospect.
Description of the drawings
Fig. 1 be by obtained purpose product burn after, one of it is characterized result using scanning electron microscope (SEM). SEM image shows in the purpose product after burning and generates substantial amounts of expanding bubble.
