Abstract
The invention relates to a method for preparing coloured fibers for ultrahigh molecular weight polyethylene (UHMWPE) ropes and nets. The method comprises the following three steps of: 1. adopting UHMWPE resins, high-density polyethylene (HDPE) and organic pigment toners to prepare a UHMWPE powdered coloured master batch; 2. using the UHMWPE resins, white oil as a solvent and the UHMWPE powdered coloured master batch to prepare coloured spinning solution, i.e. carrying out mixed swelling and carrying out extrusion spinning and water bath coagulation after cooling to prepare UHMWPE coloured gel fibers; and 3. extracting the prepared UHMWPE coloured gel fibers, carrying out hot air drying, then carrying out three-pass hot stretching after drying and finally setting the fibers. The coloured UHMWPE fibers can satisfy different specifications of ropes and fishing nets.
Description
Technical field
The present invention relates to the high-performance fiber technical field, relate to the preparation method of a kind of ultra-high molecular weight polyethylene netting with colored fibre.
Background technology
Superhigh molecular weight polyethylene fibers (UHMWPE) is one of large tec fiber in the world today three (carbon fiber, aramid fiber, UHMWPE).To succeed in developing the end of the seventies in last century, realize the high-performance fiber of a kind of high strength of industrialization, low extension, high-modulus the eighties, development is faster arranged over nearly 20 years, its production technology is all produced by the gel spinning method, main preparation methods is divided into two steps and completes: the one, by super high molecular weight powdex and a large amount of solvent preparing super molecular weight polyethylene blend spinning liquid, by twin (double) screw extruder, extrude the spray silk and be frozen into the super high molecular weight polyethylene gel fiber; The 2nd, by gel spun fiber, through extraction, dry, the super doubly hot drawing-off acquisition ultra-high molecular weight polyethylene finished fiber in three roads, fiber is white, and this fiber can not meet the color requirements such as the high-strength rope of application ocean engineering, fishing net.Secondly because the superhigh molecular weight polyethylene fibers molecular density is high, without functional group's smooth surface, the solution of also can't dyeing.
Ultrahigh molecular weight polyethylene has color fibre, is the study hotspot of current industry specialists.
Prior art (ZL200810014184.1) discloses a kind of coloured high-tenacity polyethylene fibre preparation method, it is incorporated in slab oil by the ultra-high molecular weight polyethylene powder, after adding again the inorganic pigment mixing, heating spinning super high molecular weight polyethylene gel fiber in double screw extruder, again through extraction, obtain coloured high-tenacity polyethylene fibre after drying and drawing-off, there is inorganic pigment color desalination when the Couble screw rod high-temp swelling in the method, secondly a large amount of pigment dissolved are in mineral oil solvent, be unfavorable for solvent recovery, cost is high, fiber color is shallow, the defects such as lack of homogeneity.
Prior art (201110090622.4) discloses the preparation method of the red fiber of a kind of ultra-high molecular weight polyethylene: it joins (1) red nano level organic pigment in 4,500,000 ultra-high molecular weight polyethylene powder, fully be uniformly mixed, form coloured condensate of ultra-high molecular weight polyethylene; (2) again by coloured condensate and 70
#dissolvant white oil and antioxidant carry out high shear and prepare the ultra-high molecular weight polyethylene spinning mixture; (3) step (2) spinning mixture is inputted to screw extruder with high-shear pump, extrude the spray silk and solidify coloured frozen glue precursor through cold bath, obtain the red fiber of ultra-high molecular weight polyethylene through extracting drying and Multi-stage heat drawing-off more afterwards.Through this production method, analyze: the one, exist nano-level pigment to be difficult to avoid being blended in a large amount of dissolvant white oils, affect the solvent recovery quality; The 2nd, public technology can only meet redness, yellow, orange procedure of fibre production.
Prior art (200910154196.9) discloses a kind of production method of ultra-high molecular weight polyethylene colored fine denier fiber, its three kinds implement ultra-high molecular weight polyethylene colored emulsus mixed liquor prepared by matching scheme after, all pass through double screw extruder extruding spray silk water bath processing, then become ultra-high molecular weight polyethylene colored fine denier fiber through extraction, drying, ultra-drawing.The disclosure technology one is to exist equally nano-level pigment under high-temperature fusion, is difficult to avoid pigment to be blended in a large amount of dissolvant white oils, affects the uniformity of solvent recovery quality and colored fibre, the 2nd, can only meet the fine count fiber production of 2D～2.5D * 164F.
Summary of the invention
According to the open three technology of background, show, the different defects that all exist ultra-high molecular weight polyethylene colored fibers to produce, and more can not meet the production requirement that is applied to high-strength rope, fishing net.The object of the invention is the technology of preparing that is to provide the ultra-high molecular weight polyethylene colored coarse denier fiber that the high-strength rope of preparation and high-strength fishing net use.
The present invention is a kind of ultra-high molecular weight polyethylene netting colored fibre technology of preparing, specifically implements in three steps:
Step 1:
Adopt polyvinyl resin with super-high molecular weight to add HDPE polyethylene and organic pigment toner, with vented twin-screw extruder, prepare ultra-high molecular weight polyethylene colored master batch, then the color grain of preparation is ground to form to the ultra-high molecular weight polyethylene powdery color masterbatch is arranged.
Step 2:
Select polyvinyl resin with super-high molecular weight, select white oil to make solvent, add and state the ultra-high molecular weight polyethylene powdery color masterbatch is arranged, be prepared with the color spinning solution body: input swelling still is mixed swelling, continuous stirring, reach polyvinyl resin with super-high molecular weight and ultra-high molecular weight polyethylene color masterbatch and mix the emulsion type state, and the colored resin solution after swelling is cooling, be transported to double screw extruder plasticizing extruding spray silk and water-bath and solidify, prepare ultra-high molecular weight polyethylene colored gel spun fiber.
Step 3:
By the ultra-high molecular weight polyethylene colored gel spun fiber prepared: 1. first through extraction process, with hydrocarbon cleaning agent by the white oil solvent extraction and separation; 2. the as-spun fibre after the extraction carries out hot-air seasoning again; 3. fiber Zai Jing tri-road hot-stretchs after drying; 4. fiber typing: again through HEAT SETTING, finally superhigh molecular weight polyethylene fibers being wound into to wound packages after three road hot-stretchs, is the colored fibre finished product.
This production method has: the one, and organic pigment takes full advantage of, and pigment is difficult for being blended in dissolvant white oil; The 2nd, uniform coloring, COLOR FASTNESS are high, can the sea water resistance long period of soaking and the function such as uvioresistant illumination; The 3rd, meet versicolor preparation, fiber dimensious 1600D～3200D multifilament, filament number is 5～10 DENIER, percentage elongation is 4%～4.5%, fibrous fracture intensity is 30～33g/D, can meet the instructions for uses such as high strength cord and long range fishing trawlnet, deep-sea breeding purse seine.
High-strength rope, fishing net ultra-high molecular weight polyethylene colored fibers, it is main various colored fibres that color be take black, blueness, green, coffee color, specification is with the coarse denier fiber of 1600D * 300F, 2000D * 300F, 2400D * 320F, 3000D * 320F, 3200D * 320F, filament number is 5～10 DENIER, percentage elongation is 4%～5%, coloured superhigh molecular weight polyethylene fibers of all powerful >=30g/D, can meet rope and the fishing net application of different size.
