Description
Technical field
The invention belongs to technical field of polyester fiber preparation, and in particular to a kind of original liquid coloring prepares environmentally friendly polyester fiber
Method.
Background technology
Original liquid coloring polyester fiber is exactly the fiber for carrying out spinning after first being coloured to polyester fondant again, with normal dyeing
Method is compared, and original liquid coloring fiber no longer needs road after carrying out to dye, and reduces the production cost of fiber color silk, reduce water and
The consumption of the energy, energy-saving and emission-reduction are with the obvious advantage, meanwhile, the production of original liquid coloring technology coloured fiber color is uniform, color fastness is high,
Original liquid coloring technology meets the requirement of recycling economy development, and national correlation department is advocated to be widelyd popularize in textile industry.
At present, original liquid coloring technology is there is also some defects in actual production process, and such as color adjustment is more difficult, matches somebody with somebody
Color scheme hardly possible is determined, is not suitable for small lot production etc..Therefore, most of original liquid coloring fiber produced at present is all black, state
Interior black silk accounts for more than the 60% of original liquid coloring fiber production, Chinese invention patent application CN102731754A (patent applications

Ask dyestuff or pigment, dispersant that there is resistance to elevated temperatures, industrial implementation has larger limitation.Patent of invention Chinese invention
(Patent No. CN201310147346.X, entitled " a kind of original liquid coloring prepares coloured polyester to patent CN103255498A
The method of fiber ") it is improved, it is combined, is solved with polyester fondant direct spinning process using online addition liquid mill base
Big using coloured sewage disposal difficulty caused by the colouring method of high temperature, high pressure or adding carrier, cost is high, and directly discharge can make
Into the problem of serious environmental pollution, while also solving section dry coloring method, dyestuff and feed stock chip co-blended spinning method, color
High energy consumption caused by the discontinuous methods such as master batch and feed stock chip co-blended spinning method, unit consumption is high, the problem such as product batch difference is big, but it is made
Standby dyeing system needs to protect the mixture of polyester support adipic acid and 1,3 butylene glycol through nitrogen, heated up, insulation reaction extremely
Acid value is 10, vacuum distillation 1 hour under 6.67~8.00kPa, and industrializing implementation is relatively complicated.Thus, research and develop a resistance to constant temperature
Degree, stable dispersion, environmental protection, dyeing system easy to operate are the important measures of original liquid coloring polyester fiber production.
Meanwhile, in recent years, ecological textile is all vigorously advocated in countries in the world, and also active development and production are beneficial by research staff
In health, be conducive to the ecological textile of environmental protection, it is nontoxic in itself that ecological textile does not require nothing more than textile, with
Human contact is non-stimulated, while requiring that its production and processing technology such as prints and dyes, arranges process and do not produce poisonous and harmful substance, dyestuff
And printing and dyeing assistant should have the biological degradability that security is become reconciled.It is external to APEO (Anhui base phenol polyethenoxy ether, NPEO and
OPEO limitation requirement) is proposed, and contains NPEO in the terylene spinning finish that most enterprises domestic at present use, after testing
APEO content is 100-250PPM on final products.
