The invention uses conventional equipment, has simple process, easy operation and low cost, and is convenient for industrialized popularization and application.
Description
Technical field
The present invention relates to functional chemical fibre manufacturing technology, be specially a kind of method of producing skin-core structural anti-bacterial fiber by melt direct spinning, belong to chemical fiber field.
Background technology
At present, the kind of domestic anti-bacterial fibre and the mode of production thereof have a lot, sum up to get up to comprise: the anti-bacterial fibre technology of producing is spun in the twin-screw section; The island composite algorithm is produced the anti-bacterial fibre technology; Antibacterial functions liquid facture is produced anti-bacterial fibre technology etc.Though these methods also can production performance anti-bacterial fibre preferably, all have weak point.Twin-screw method and island composite algorithm production procedure are long, complex procedures, and technique controlling difficulty is big, and the product physical and chemical performance is inhomogeneous.Problems such as functional liquid is handled rule and existed wastage of material big, and environmental pollution is serious.
Summary of the invention
At the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined has provided a kind of manufacture method of new anti-bacterial fibre.
The objective of the invention is to design a kind of functional fiber with skin-core structure, the core-skin volume ratio is 2: 8～6: 4; The percentage by weight prescription of its cortex material is: cortex polymer 75～85%, antimicrobial nano powder 15～25%, coupling agent 0.2～4%; Its core layer material is 100% polymer.
The object of the present invention is achieved like this:
1, makes the cortex material melt: after by the prescription of described cortex material cortex polymer, antimicrobial nano powder and coupling agent evenly being mixed, under 180～290 ℃ of temperature, extrude, obtain described antiseptic cortex melt through twin-screw;
2, above-mentioned cortex melt is injected composite component by the method for frequency conversion metering; Another melt inlet of composite component directly is connected with the measuring pump of melt Direct Spinning.
3, compounding flux sprays from the spinnerets of composite component, and melt spins that spinning is carried out in production procedure, reeling makes the antibacterial functions fiber of skin-core structure of the present invention routinely then.
Antimicrobial nano powder diameter of the present invention should be the following fine particle of 45nm.
High polymer of the present invention includes but not limited to high polymers such as PET, PBT, PTT, and described core-skin high polymer is identical
Anti-bacterial fibre of the present invention spins functional fibre owing to adopted core-sheath composite structure, its core-skin layer in fact to be equivalent to section, and its sandwich layer is because of being identical with cortex major part component, thereby can solve qualitative compatibling problem, lamination can not occur.Simultaneously, make, can also solve the not wide old trouble of other composite spinning method technology fine setting property by the multiple unit tube structural reform.
The present invention uses conventional equipment, and technology is simple, and processing ease is with low cost, is convenient to industrialization promotion and uses.
The specific embodiment
Below provide 1 specific embodiment of the present invention:
Get 80 parts of dried polyethylene terephthalate (weight, down together); Average grain diameter is 17 parts of 35nm and surface treated silver nitrate anti-bacterial powder, and 3 parts of coupling agents after abundant mixing, are extruded through twin-screw under 286 ℃, produce the cortex melt; Produce antibacterial PET long filament with the fused mass directly spinning mode of production by 3: 7 fiber core-skin weight ratios with core-sheath composite structure.
Claims (5)
