Abstract
The invention discloses a chinlon 6 drawn yarn based on a rich-lanthanum rare earth additive. The rich-lanthanum rare earth additive is added in a spinning process. A preparation method of the chinlon 6 drawn yarn comprises the following steps of drying of a chinlon slice, extrusion and fusion, box body spinning, metering and extrusion, component spinning, lateral blowing, cooling formation, execution of oiling and bundling, a thread rod, winding for the formation of a cylinder, inspection and stage packaging. The rich-lanthanum rare earth additive is added in the step of extrusion and fusion; and a spinneret orifice is adopted as a four-angle star spinneret plate in the spinning component. Compared with the prior art, the preparation method has the differences that the rich-lanthanum rare earth additive is introduced; the chinlon molecular structure is changed fundamentally; the tensile strength of chinlon is enhanced; and meanwhile, the spinnability of the chinlon slice melt is improved. On the other hand, rare earth is abundant in China; a rich-lanthanum rare earth element is taken as the additive to be introduced for processing and manufacturing of the chinlon 6 drawn yarn; and the rate earth resource can be fully utilized.
Description
Technical field
The present invention relates to a kind of polyamide fibre 6 and manufacture method thereof, especially a kind of polyamide fibre 6 drafted fibres and manufacture method thereof based on the lanthanum rich rare earth additive.
Background technology
The principal item of polyamide fibre is the fatty polyamide fiber, and it can be synthetic with a kind of monomer, as lactam or amino acid.Arabic numerals after the polyamide fibre title namely show lactam used or amino acid whose carbon atom number at this moment, as polyamide fibre 6, polyamide fibre 11 etc.Polyamide fibre 6 is polycaprolactam fiber, 412 pages of " the chemical fibre dictionaries " of the front page second impression in 95 years namely disclose this concept: polycaprolactam fiber is called for short polyamide fibre 6 in China, product has monofilament, multifilament, textured filament and staple fibre etc., adopts melt direct spinning or slice spinning legal system to get finished fiber.Polyamide fibre 6 products have the characteristics such as high strength, wear-resisting, flexibility and skin sense of touch gentleness, has wide purposes at clothes, silk, umbrella, fishnet silk, cord fabric thread, BCF carpet silk and engineering plastics fields, therefore belong to the main flow kind of domestic chemical fibre manufacturing enterprise, nylon fabric is also prevailing fabric on market.Thin dawn of nylon-6 fiber, functionalization had both met national industrial policy, complied with again development priority and the trend of textile of chemical fibre industry, fashion trend and the voguish style of having catered to following high-grade fabric.In order to satisfy better people's living needs, be necessary to develop new polyamide fibre 6 drafted fibre kinds.
Summary of the invention
The objective of the invention is good polyamide fibre 6 drafted fibres based on the lanthanum rich rare earth additive of a kind of TENSILE STRENGTH that design for the deficiency that solves above-mentioned technology, the present invention has also designed the manufacture method of aforementioned polyamide fibre 6 drafted fibres based on the lanthanum rich rare earth additive.
Polyamide fibre 6 drafted fibres based on the lanthanum rich rare earth additive that the present invention is designed have added the lanthanum rich rare earth additive in spinning process.
The manufacture method based on polyamide fibre 6 drafted fibres of lanthanum rich rare earth additive that the present invention is designed comprises the steps: that slices of caprone is dry, and------------------boundling oils, and---------check---divides grade packaged the seal wire rod cooling forming lateral blowing metering extruding-filament spinning component spinning manifold extrusion molten to be wound into cylinder; Added the lanthanum rich rare earth additive in the extrusion molten step; In the filament spinning component step, adopting spinneret orifice is the spinnerets of four jiaos of stars.
As preferably:
Described spinnerets specification is diameter 0.2mm, and draw ratio is 3.0;
Extruder temperature is 266 ± 2 ℃, 260 ± 2 ℃, a district, 266 ± 2 ℃, 2nd district, San Siwu district in the extrusion molten step; Pressure is 12MPa;
Spinning speed is 3800-4200m/min in filament spinning component;
In the lateral blowing step, 30-40 ℃ of lateral blowing temperature, humidity 45-60%;
In the boundling step that oils, upper oil mass is 1.2 ± 0.2%.
Polyamide fibre 6 drafted fibres and manufacture method thereof based on the lanthanum rich rare earth additive that the present invention is designed, it is put unlike the prior art and is to have introduced the lanthanum rich rare earth additive, fundamentally changed the polyamide fibre molecular structure, strengthened the TENSILE STRENGTH of polyamide fibre, improve simultaneously the spinnability of slices of caprone melt, but reduced the requirement to spinning equipment when enhancing product performance; On the other hand, China is rare earth resources big country, in rare earth element, the scopes of application such as neodymium, dysprosium, praseodymium are wider at present, and lanthanum forms a large amount of overstocking because the scope of application is less, the technology of the present invention is introduced rich lanthanum LREE in the processing and manufacturing of nylon-6 fiber as additive, can take full advantage of rare earth resources, this polyamide fibre 6 drafted fibres also have the characteristics that cost is low, price is excellent.
