Abstract
The invention relates to a technique method for manufacturing a PLA flame-retardant fiber which is characterized in that the invention is a manufacturing method for manufacturing the melt made by PLA into a sheath-core PLA fiber with a compound spinning box body and a sheath-core component; wherein, the PLA melt is a core layer; the proportion by weight of the sheath and the core is 2:8 to 6:4; the weight percentage prescription of the sheath layer material is 75 to 85 percent of sheath layer PLA polymer, 15 to 25 percent of flame-retardant master grains and 0.2 to 4 percent of a resin acceptor; the core layer material is 100 percent of PLA polymer. The method of the invention has the advantages of normal device, simple technique, easy operation, low cost and being convenient for industrial popularization and application.
Description
Technical field
The invention belongs to the textile chemical fiber field of production, be specifically related to the production method of PLA (PLA) fire resistance fibre.
Background technology
Acid fiber by polylactic is present representative instance in the non-oil system that makes of the use pure natural and renewable resource of exploitation, environmentally friendly, the Biodegradable material field in the world.Acid fiber by polylactic has merged the excellent properties of natural fabric and synthetic fiber, is the environment recycled material of 21 century, is novel ecological property fiber.PLA (PLA) fiber has the characteristics of natural fabric and synthetic fiber concurrently, moisture absorbing and sweat releasing evenly, do soon, anti-flammability is low, flue dust is little, heat is distributed little, avirulence, fusing point is low, resilience good, refractive index is low, bright in luster, not grow bacterium and smell retention index low etc.The fabric of being made by acid fiber by polylactic has good drapability and feel, and made ready-made clothes has comfortable and easy to wear, and tool wear, wrinkle resistance, uvioresistant and lead wet effect, and can discharge characteristic such as human scent.The PLA fire resistance fibre not only has the characteristics of above-mentioned fiber, and more possesses good security performance, and fabric is nonflammable, is real intelligent multi-function fiber, and Application Areas is abundanter.
At present, the mode of production of domestic fire-retardant PLA fiber has a lot, comprises technology such as co-blended spinning, composite spinning, graft copolymerization.Though these methods also can production performance PLA fire resistance fibre preferably, all have weak point.The common drawback that they have is exactly that production procedure is long, complex procedures, and technique controlling difficulty is big, and the product physical and chemical performance is inhomogeneous, and production cost is higher, and the limit oxygen quotient is low, causes effective popularization of product to form obstruction.
Summary of the invention
The objective of the invention is to design a kind of functional PLA fiber with skin-core structure, the core-skin weight ratio is 2: 8～6: 4; The percentage by weight prescription of its cortex material is: cortex PLA polymer 75～85%, fire-retardant master granule 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 cortex material: after by the prescription of described cortex material cortex polymer, fire-retardant master granule and coupling agent evenly being mixed, under 280-295 ℃ of temperature, extrude through twin-screw and to obtain described cortex melt.
2, make core-skin composite flame-proof fiber, the cortex melt with above-mentioned 1 step gained by described core-skin weight ratio, spins out undrawn yarn with core-skin composite spinning silk machine; Again with undrawn yarn under 70～100 ℃ of temperature, stretch 2～4 times, can obtain the PLA fire resistance fibre of described skin-core structure.
Fire resistance 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.
Progress effect of the present invention, conventional equipment, 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 PLA sections (weight, down together); Average grain diameter is 17 parts of 45nm and surface treated halogen-free flameproof master batches, and 3 parts of coupling agents after abundant mixing, are extruded through twin-screw under 210-225 ℃ and produced the cortex melt; Fiber sheath core volume by 3: 7 spins out undrawn yarn than with core-skin composite spinning silk machine; Again undrawn yarn is stretched 2 times under 100 ℃ of temperature, obtain a kind of fire-retardant PLA filament fiber.
Claims (2)
1, the process of PLA fire resistance fibre production, its feature work flow process is as follows:
Melt B is to adopt fire-retardant master granule 15～25% high polymer blend identical with PLA melt A to extrude the melt of making by twin-screw.
2, the method for claim 1: it is characterized in that cortex percentage by weight prescription is: cortex polymer 75～85%, fire-retardant master granule 15～25%, coupling agent 0.2～4%.
