Description
Technical field：
The present invention relates to non-woven fabrics processing technique fields, and in particular to a kind of high-performance antibiosis polypropylene spunbond non-woven fabrics adds
Work technique.
Background technology：
Polypropylene spunbond non-woven fabrics is one kind of non-woven fabrics, be with polypropylene is raw material, polymerize networking by high temperature wire drawing,
Then reusable heat rolls the one kind of method bonding at cloth.It is wide at present since technological process is simple, yield is big, non-toxic to humans
The various fields such as general application hygienic material.
Since polypropylene spunbond non-woven fabrics is chiefly used in the processing of hygienic material, in order to improve the safety in utilization of hygienic material,
Need polypropylene spunbond non-woven fabrics that there is anti-microbial property.But rapidoprint polypropylene of polypropylene spunbond non-woven fabrics itself does not have anti-
Bacterium acts on, thus antibacterial polypropylene spunbond non-woven fabrics currently on the market largely using chemical mode, photocatalyst or nano silver from
Subprocessing technology carries out antibacterial processing, but deficiency is individually present：Though chemical mode can antibacterial, most of chemicals itself is easy
Human body is damaged；Though photocatalyst is safe and effective, cost is higher；Though nano silver has bacteriostasis, antibacterial ability weaker.
Invention content：
Technical problem to be solved by the present invention lies in provide one kind to be conducive to improve non-woven fabrics safety in utilization and antibacterial
The processing technology for the high-performance antibiosis polypropylene spunbond non-woven fabrics that significant effect, anti-microbial property are stablized.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of processing technology of high-performance antibiosis polypropylene spunbond non-woven fabrics, including following operating procedure：
(1) preparation of carboxyted polypropylene：Polypropylene powder and nitric acid are sufficiently mixed, 130 DEG C of heat preservations is again heated to and stirs
Reaction is mixed, after reaction by gained mixture cooled to room temperature, and nitric acid is removed through washing, finally vacuum dried,
Powder is made to get carboxyted polypropylene in crushing；
(2) polyacrylic antibacterial modified：Chitosan hydrochloride is dissolved in water, made carboxyted polypropylene is added, fills
Divide stirring, and dilute sulfuric acid is added dropwise and adjusts pH value to 5, the reaction of reflux state insulated and stirred is again heated to, after reaction by gained
Then mixture cooled to room temperature is added dropwise inorganic alkali solution and adjusts pH value to 7, filtering, water-washing desalting is most done through vacuum afterwards
Particle is made to get chitin modified polypropylene in dry, crushing；
(3) processing of web：Made chitin modified PP GRANULES is added in screw extruder and is melted, then through spray
Silk networking is to get web；
(4) nonwoven molding with cloth：By made web it is hot rolled at cloth to get antibacterial polypropylene spunbond non-woven fabrics.
The mass fraction of nitric acid is 65-70% in the step (1), and the mass ratio of polypropylene powder and nitric acid is 15-30:
1-10。
Chitosan hydrochloride in the step (2), carboxyted polypropylene mass ratio be 5-10:35-50.
In the step (2) inorganic base in sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate one
Kind.
The made web of the step (3) has also carried out at secondary antibacterial before entering step (4) non-woven fabrics processing and forming
Reason.
The concrete operations of the secondary antimicrobial treatment are：Web is preheated to 125-130 DEG C, and uniformly on web
Secondary antimicrobial treatment solution is sprayed, the amount of spraying is 30-50g/m2, it is then transferred to standing 3-5h, 55- in 105-110 DEG C of environment successively
It is stood in 2-3h, 5-10 DEG C of environment in 60 DEG C of environment and stands 3-5h.
The secondary antimicrobial treatment solution is made of carrier nano magnesia and Chinese medicine antibacterial extracting solution, and preparation method is：
20g nano magnesias are added in 1kg Chinese medicine antibacterial extracting solutions, 15-30min is stood after being sufficiently stirred, recycle microwave reaction
Device microwave return stirring 5min continues microwave return stirring 5min after stopping 5min, stops microwave return stirring again after 5min
5min so repeats, so that microwave return stirring total time is reached 30min, cooled to room temperature is to get secondary antimicrobial treatment
Liquid.
The average grain diameter of the nano magnesia is 50nm.
The Chinese medicine antibacterial extracting solution is made of Chinese medicine composition through water extraction, and preparation method is：By 30g the bark of the root or stem of the tree of heaven,
20g Verbena officinalis, 15g Kadsura Root-barks, 15g Siberian elm brak, 10g gold boiling grass, 5g Mongollian Thyme Herbs, 5g berberis poiretiis, 5g Ranunculus sceleratus, 3g Blumea balsamiferas,
2g potentilla chinensis, 0.5g styraxes are added in the water of 5 times of Chinese medicine gross weights, and reflux state insulated and stirred 3h, mistake are heated to after impregnating 12h
Filtrate is collected in filter, filter residue is added in the water of 3 times of Chinese medicine gross weights, is again heated to reflux state insulated and stirred 2h, is filtered, and is closed
And filtrate is to get Chinese medicine antibacterial extracting solution.
The beneficial effects of the invention are as follows：
(1) present invention introduces carboxyl using nitric acid to polypropylene molecule structure end carboxylated, recycles chitosan
Institute's hydroxyl and amino are reacted with amide condensed to be introduced on polypropylene with carboxyl generation esterification respectively in molecular structure
Chitosan, to assign polypropylene antibacterial performance using the antibacterial characteristics of chitosan；
(2) present invention is born when prepared by secondary antimicrobial treatment solution using nano magnesia as carrier using its absorption property
Chinese medicine antibacterial ingredient is carried, to introduce natural antibacterial ingredient on made non-woven fabrics, to strengthen the anti-microbial property of made non-woven fabrics；
(3) formula of Chinese medicine antibacterial extracting solution preparation Chinese medicine composition used of the present invention follows strictly the compatibility of monarch
Relationship, using pathogenic bacteria as controlling object, antimicrobial component directly acts on pathogenic bacteria, to show good anti-microbial property；
And the formula of the Chinese medicine composition is obtained by experiment sieving many times, wherein the addition and its dosage per a herb are all
By verifying repeatedly, to be the identical or close similar Chinese medicine of pharmacological property can not replace easily；
(4) nano magnesia of the present invention itself has antibacterial action, and because free hydroxyl is contained on its surface after as carrier
Base thus can with esterification or amidated carboxyl reacts to Chinese medicine antibacterial ingredient is firmly attached to poly- completely on polypropylene
On tacryl, and then significantly improve the anti-microbial property of made non-woven fabrics；
(5) the made polypropylene spunbond non-woven fabrics of the present invention not only has significant anti-microbial property, while anti-microbial property is stablized, and resists
Bacterium timeliness is long；And the mechanical strength of made polypropylene spunbond non-woven fabrics is high, and good permeability is non-toxic to humans, is suitable for adding
Work is made operation clothing, sheet, diaper, isolation clothes, visits the medical and hygiene articles such as clothes.
