Description
Technical field
The invention belongs to technical field of polyester fiber preparation, be specifically related to a kind of method that original liquid coloring prepares environmental protection polyester fiber.
Background technology
Original liquid coloring polyster fibre be exactly first painted to polyester fondant after carry out the fiber of spinning again, compared with common staining method, original liquid coloring fiber no longer needs to carry out the dyeing of rear road, reduce the production cost of fiber look silk, decrease the consumption of water and the energy, energy-saving and emission-reduction are with the obvious advantage, simultaneously, the coloured fiber color that original liquid coloring technology is produced is even, COLOR FASTNESS is high, and original liquid coloring technology meets the requirement of recycling economy development, and national correlation department is advocated and widelyd popularize at textile industry.
At present, original liquid coloring technology also also exists some defects in actual production process, as more difficult in color adjustment, and scheme of colour difficulty is determined, is not suitable for small lot batch manufacture etc.Therefore, the original liquid coloring fiber major part of current production is all black, domestic black silk accounts for more than 60% of original liquid coloring fiber production, (number of patent application is CN201210227606.X to Chinese invention patent application CN102731754A, denomination of invention is " a kind of polyester black original liquid coloring method "), (number of patent application is CN201410709477.7 to Chinese invention patent application CN104499079A, denomination of invention is " a kind of original liquid coloring prepares the method for black polyester fiber "), (patent No. is CN201310742922.5 to Chinese invention patent CN103710772A, denomination of invention is " fiber original liquid coloring superfine carbon black aqueous color paste "), (patent No. is CN201420735798.X to Chinese utility model patent CN204237904U, utility model name is called " a kind of original liquid coloring prepares the process units of black polyester fiber ") all disclose original liquid coloring method and prepare black polyester fiber.(number of patent application is CN201310150118.8 to Chinese invention patent application CN103215656A, denomination of invention is " solvent carrier of polyester fiber spins front original liquid coloring technique "), (patent No. is CN201310147346.X to Chinese invention patent CN103255498A, denomination of invention is " a kind of original liquid coloring prepares the method for coloured polyester fiber "), (patent No. is CN201210584296.7 to Chinese invention patent CN103031755A, denomination of invention is " the ethylene glycol pigment dispersion and preparation method thereof for terylene original liquid coloring "), (patent No. is JP1998291568 to Japan Patent JP2000119913 (A), denomination of invention is for " ア Network リ Le system original liquid coloring Xian Victoria System makes with Spinning yarn Yuan Ye System making method, Preparationofdopeforproducingacrylicspun-dyedfiber ") disclose original liquid coloring method and prepare other color polyester fiber, " modern textile technology " (Zhu Song, the present situation of production technology of original liquid coloring polyster fibre and market prospects, modern textile technology [J], 6th phase in 2013, 32-35) disclose present situation of production technology and the market prospects of original liquid coloring polyster fibre, " printing and dyeing assistant " (Zhang Qingshan, Mao Qinghui, Mao Zhiping, the Study and appliance of organic solvent system synthetic fiber original liquid coloring agent, printing and dyeing assistant [J], 26th volume the 9th phase in 2009, 13-16) inquire into different hyper-dispersant kind, hyper-dispersant consumption, the sand milling time is to N, N-dimethylacetylamide is the impact of the inorganic pigment color paste system stably dispersing performance of decentralized medium.
Original liquid coloring prepares colored fibre can by the painted mode of polymerization process, such as (number of patent application is CN201410709477.7 to Chinese invention patent application CN104499079A, denomination of invention is " a kind of original liquid coloring prepares the method for black polyester fiber "), prepare black fiber; (patent No. is CN201210584296.7 to Chinese invention patent CN103031755A, denomination of invention is " the ethylene glycol pigment dispersion and preparation method thereof for terylene original liquid coloring ") prepare ethylene glycol pigment dispersion, shaping by the technique such as ester exchange reaction, polymerisation direct fabrics, thus require dyestuff or pigment, dispersant there is resistance to elevated temperatures, industrial implementation has larger limitation.(patent No. is CN201310147346.X to patent of invention Chinese invention patent CN103255498A, denomination of invention is " a kind of original liquid coloring prepares the method for coloured polyester fiber ") it is improved, the liquid mill base of online interpolation is adopted to combine with polyester fondant direct spinning process, solve employing high temperature, coloured sewage disposal difficulty that high pressure or the colouring method adding carrier cause is large, cost is high, direct discharge can cause the problem of serious environmental pollution, also solve section dry coloring method simultaneously, dyestuff and feed stock chip co-blended spinning method, the energy consumption that the discontinuous methods such as Masterbatch and feed stock chip co-blended spinning method cause is high, unit consumption is high, product criticizes the difficult problems such as difference is large, but it prepares dyeing system needs polyester support adipic acid and 1, the mixture of 3-butanediol is through nitrogen protection, heat up, insulation reaction to acid value is 10, decompression distillation 1 hour under 6.67 ~ 8.00kPa, industrializing implementation is comparatively loaded down with trivial details.Thus, research and develop resistance to uniform temperature, stable dispersion, environmental protection, dyeing system easy and simple to handle be the Important Action that original liquid coloring polyester fiber is produced.
Simultaneously; in recent years; ecological textile is all vigorously advocated in countries in the world; research staff also active development and production is of value to health, is conducive to the ecological textile of environmental protection; ecological textile not only requires that textiles itself is nontoxic; non-stimulated with human contact, require that its production and processing technology such as processes such as printing and dyeing, arrangement do not produce poisonous and harmful substance, dye well printing and dyeing assistant should have the biological degradability that security is become reconciled simultaneously.Limitation requirement is proposed to APEO (Anhui base phenol polyethenoxy ether, NPEO and OPEO) abroad, and all containing NPEO in the terylene spinning finish that current domestic most enterprise uses, on final products, the content of APEO is 100-250PPM after testing.
