The method adopts 0.5 to 1.0 weight percent of imidazoline substances as bacteriostatic agents , 0.05 to 0.07 weight percent of alkyl ammonium bromide substances as phase transformation agents (B) and 98.93 to 99.45 weight percent of polypropylene to prepare bacteriostatic master batches, and then 5 to 10 weight percent of bacteriostatic master batches and 90 to 95 weight percent of polypropylene are mixed and spun to prepare the product of the invention, wherein the product contains 500ppm to 1000ppm of bacteriostatic agents, thereby solving the problem of poor bacteriostatic effect and avoiding the post-finishing process. The product has obvious inhibition effect on various bacteria and lasting antibacterial property, and can be used in the health care field and various industries such as clothing, household fabrics and the like.
Description
The present invention relates to a kind of bacteriostatic PP fiber and manufacture method thereof.
In the prior art, the report of bacteriostatic fiber is more, but generally all in polymer, add ceramic, fragrant halogen compounds, organosilicon quaternary amines, copper, zinc, silver-colored plasma compound etc., have plenty of and fiber is carried out back arrangement give its bacteriostasis, the shortcoming of said method be all to fiber physical property or the fungistatic effect in using have a negative impact.
Bacteriostatic agent used in the present invention-naphthenic acid imidazoline compounds is a kind of fine chemical product with multiple excellent properties, report as bactericide and corrosion inhibiter is abroad just arranged the end of the sixties, U.S. MillmasterOnyx and Nalco company have developed naphthenic acid imidazoline respectively and have made bactericide, microbicide and high-efficient corrosion inhibitor product, be used for fuel, industry water, lubricating oil, cosmetics to prevent growth of microorganism, also can be used for epoxy curing agent and curing accelerator occasion, but do not see report so far as the chemical fibre bacteriostatic agent.U.S. US3705027 patent report, the growth dilution test method of application standard (Stamdor Groth DintionTest Method) is carried out bactericidal assay, 1-aminoethyl-2-naphthenic acid imidazoline has the good sterilization effect to Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, hammer mushroom, aspergillus niger, water polo algae, PCs, its minimal inhibitory concentration 10ppm-500ppm.
The object of the present invention is to provide a kind of mattress polypropylene fibre and manufacture method thereof of pressing down, use the imidazolines material to make bacteriostatic agent, and add a spot of agent (also being bactericide) that changes mutually, obtain the good bacteriostatic PP fiber of fungistatic effect, and a kind of fiber process process no change is provided, fiber physical property is not had influence, and do not need the arrangement of any back, promptly give the manufacture method that fiber has the bacteriostatic PP fiber of remarkable fungistatic effect.
The objective of the invention is to realize by the following technical solutions: with imidazolines material (bacteriostatic agent A) with change mutually that agent (B) (also being bactericide) mixes with polypropylene and granulation obtains the antibacterial master batch of polypropylene; then antibacterial master batch is mixed by a certain percentage with fibrous polypropylene; spinning under 230-280 ℃ temperature; again through coiling, boundling, drawing-off, curl, process such as typing; promptly get bacteriostatic PP fiber, contain the bacteriostatic agent of 500ppm-1000ppm (weight) in this novel bacteriostatic fiber.The present invention's technical scheme preferably is that bacteriostatic agent (A) selects for use chemical formula to be

In implementing process of the present invention, bacteriostatic agent (A) can be wherein a kind of or several mixing and a usefulness with changing agent (B) mutually respectively, can both play same effect.In view of the consumption that changes agent (B) mutually very few, so often only add wherein a kind of in force, to simplify the operation.
The present invention's technical scheme preferably also can be: the content of bacteriostatic agent in the antibacterial master batch (A) is 0.5%-1.0% (weight), the content that changes agent (B) mutually is 0.05%-0.07% (weight), polypropylene content is 98.93%-99.45% (weight), the consumption that presses down mattress agent (A) in the preparation is not wanted too much or very few, the highest described consumption can reach the fungistatic effect of expection fully, but then can not reach required fungistatic effect if its consumption is crossed when hanging down, especially negative bacillus such as proteus and Pseudomonas aeruginosa be lost fungistatic effect.
The present invention's technical scheme preferably can be again: when manufacturing presses down the mattress master batch, need earlier in bacteriostatic agent (A) and the mixed liquor that changes agent (B) mutually adding desire to prepare the water of antibacterial master batch gross weight 1%-3%, make bacteriostatic agent be transformed into emulsion, be convenient to bacteriostatic agent good dispersion is arranged in base-material, get the polypropylene powder of required polypropylene gross weight 10% then, stir, and under 100-110 ℃ temperature dry 3-4 hours, remove added water in the aforementioned process, again all the other 90% polypropylene powders or pellet are added and evenly mix.With granulation screw Cast Strip, pelletizing, promptly make the antibacterial master batch that contains 5000ppm-10000ppm (weight) bacteriostatic agent.In implementation process, described amount of water is not strict, as long as can make bacteriostatic agent be transformed into emulsion, and be convenient to make powder to disperse, stirring gets final product.
The present invention's technical scheme preferably can also be: get aforesaid antibacterial master batch, press the fibrous polypropylene pellet or the powder blend of master batch 5%-10% (weight) and 90%-95% (weight), spinning under 230-280 ℃ temperature, and then through drawing-off, curl and typing etc. a series of with make the plain polypropylene fiber same after processing, promptly obtain the bacteriostatic PP fiber that bacteriostatic agent content is 500ppm-1000ppm (weight).In specific implementation process, need control antibacterial master batch and polyacrylic ratio well, guarantee that the bacteriostatic agent content in the fiber is 500ppm-1000ppm (weight).
The present invention has following tangible advantage:
1, fungistatic effect is remarkable: product of the present invention carries out external bacteriostatic experiment analysis by training center of clinical pharmacology country of Hunan Medical University.
(1) bacterial strain: staphylococcus aureus, hemolytic streptococcus, proteus, Escherichia coli, Pseudomonas aeruginosa, candida albicans.
Cultivate: Mueler-Hinfon agar medium, husky Bao Shi agar medium.
(2) method: (the QninnShi method comes from H.Qnin:Appl Microbiol, 1962 to the seed agar cultivation; 10:75)
