Background technology
Human living environment exists a large amount of microorganisms, comprises various bacteriums and fungi, and they bring fatal diseases under certain condition even to the mankind, and society is caused very big harm.Statistics according to world WHO tissue; The death that the whole world causes because of bacterial infection every year is 1,700 ten thousand people; Account for 1/3 of dead population, the harm of the SARS that the current whole world faces " German Escherichia coli " etc. makes the common people be concerned about human lives's material on every side day by day.Chitin has extensively been applied to industries such as the medical treatment, building materials, clothes, lining of household consumption in the world.
BCF is the english abbreviation of BULK CONTINUOUS FILAMENT; The meaning is continuous bulk filament; Be the most frequently used, most economical processing method in the carpet matte material, because the processing technology of BCF can make yarn form three-dimensional crimp; Its covering performance is best, uses minimum material can reach best coverage effect.
The market scale of appropriate authority prediction chitin Related product in the world has 40,000,000,000 dollars.Expect 2015 and can form and surpass 1,000 hundred million dollars market scale.Chitin has 10,000,000,000 yuan market capacity in China every year, predicts that simultaneously the economic benefit of chitin also will account for 10% market in the environment industry, develops to the annual average growth rate with 13% of the year two thousand twenty.Estimate that the domestic market scale after 5～10 years can reach tens billion of units.Chitin is just progressing into people's life and is demonstrating the flourish impetus.
Summary of the invention
The objective of the invention is on the basis of existing technology, a kind of production method of chitin antibacterial mildew-resistant METHOD FOR POLYPROPYLENE BCF long filament is provided.The carpet that this chitin antibacterial BCF long filament is processed is through the standard testing of U.S. ATCC antibacterial tests, and it is antibacterial can to reach higher level with the mildew-resistant rate.
The object of the invention can reach through following measure:
A kind of production method of chitin antibacterial mildew-resistant METHOD FOR POLYPROPYLENE BCF long filament: polypropylene chip through screw rod carry out melt-out spinning and the cooling after; The mixed solution of chitin preparation and spinning oil is sprayed on the as-spun fibre surface; Emitted dose is 0.9～1.3% of an as-spun fibre quality; Under air pressure 0.4～0.6 crust, carry out preparatory network then, carry out drawing-off, BCF bulking, cooling and shaping, output, entanglement network and coiling again, preparation METHOD FOR POLYPROPYLENE BCF long filament; The mass ratio of chitin preparation and spinning oil is 0.25～0.40:1 in the wherein said mixed solution.
The invention also discloses a kind of production method of concrete chitin antibacterial mildew-resistant METHOD FOR POLYPROPYLENE BCF long filament, it comprises the steps:
(1) preliminary treatment: the mixed of chitin preparation and spinning oil being pressed mass ratio 0.25～0.40:1 is even, obtains allocating solution;
(2) polypropylene chip carries out melt-out spinning through screw rod;
(3) cooling;
(4) the allotment solution that pre-treatment step is obtained passes through finish pump metered injection on the as-spun fibre surface, and emitted dose is controlled at 0.9～1.3% of as-spun fibre quality;
(5) preparatory network, air pressure 0.4～0.6 crust;
(6) drawing-off;
(7) BCF bulking;
(8) cooling and shaping, output, entanglement network and coiling.
The shitosan that chitin preparation among the present invention is meant, its average molecular weight range can be 30～400,000, and preferred 34～360,000; Its viscosity is 0.7～0.9pa.s, preferred 0.8pa.s.
In said method, the mass ratio of chitin preparation and spinning oil is preferably 0.25～0.40:1 in the mixed solution of said chitin preparation and spinning oil (promptly allocating solution), and further preferred 0.25～0.35:1 most preferably is 0.3:1.In advance the air pressure during network is preferably 0.5 crust.
In this method polypropylene is carried out in the step of spinning, other steps except that preliminary treatment, injection and preparatory network can be with reference to conventional polypropylene BCF continuous yarn spinning step.Melt extrude etc. through screw rod under 220-240 ℃ like polypropylene.
In a kind of preferred version, the emitted dose in as-spun fibre jet surface chitin preparation and spinning oil mixed solution process is 0.9～1.3% of an as-spun fibre quality, and is preferred 1.0～1.1%, further is preferably 1%.
The prepared METHOD FOR POLYPROPYLENE BCF long filament of this method; Because the main chemical bond that passes through links to each other with substrate macromolecule material; And be aided with the chitin of specific proportioning and the synergy of polypropylene fibre and other components; Make that long filament need not promptly to have splendid antibacterial and mildew-resistant rate through other processing again, be fit to very much be applied to antibacterial mildew-resistant and weave the field, like carpet weaving etc.The METHOD FOR POLYPROPYLENE BCF long filament that this law obtains has also been kept better physical and mechanical performance when having antibacterial preferably fungicidal properties, like the METHOD FOR POLYPROPYLENE BCF long filament of embodiment 1 gained; Its fracture strength 2.1cN/dtex; Elongation at break 39.3%, boiling water shrinkage 2.5%, 25/meter of nexus.
Carpet by gained chitin antibacterial BCF long filament of the present invention is processed is tested bacteriostasis rate through U.S. ATCC antibacterial and mouldproof test standard: staphylococcus aureus 99.4%; Pneumobacillus 99.9%.Mildew-resistant progression: 1 grade of aspergillus niger.
Adopt the carpet of this law preparation to have fabulous performance, expection will drive the Related product development of domestic spinning industry and carpet industry, form a relatively integrated industrial chain.This technology mainly links to each other with substrate macromolecule material through chemical bond, has not only further guaranteed the security of using, and has guaranteed the long-lasting of antibacterial effect.Compare with the like product on the present international market, it is more lasting that this product has antibacterial effect; High-efficiency broad spectrum is antibiotic; Use safer nontoxic outstanding advantage.
