Description
Technical field
The present invention relates to a kind of preparation method of fiber, especially a kind of preparation method of electromagnetic protection fibre in differentiation.
Background technology
Common textiles has insulation, protection health or other monistic functions; But at present present stage, people live in a digitized environment, have been full of harmful electromagnetic wave in this environment.
For above-described problem, anti-electromagnetism and the far textiles of protection have been produced at present, but there is following some shortcoming in this textiles: first, adopt functional finishing agent to make by the rear arrangement of fabric, wherein functional particles is attached to the surface of fiber, particle is easy to come off, not water-fastness, functional can not be lasting; The second, additive and carrier are made to portion, No. six sections of polyamide fibre, as another part, are made composite fibre by two parts of composite spinnings, and this production technology is comparatively complicated, the investment of equipment title Russia large, that produce can not be higher; The 3rd, functional particles is added in synthetic system, make the section textile fabric containing functional particles, but the viscosity increase that makes the adding of functional particles synthetic system is large, be not easy to control while producing, comparatively serious to the wearing and tearing of equipment, to be subject to the restriction that synthesizer is larger in addition, produce dumb; The 4th, function ceramics particle and dispersant and carrier etc. are made to master batch, adopt the manufacture of masterbatch injection co-blended spinning technology to form, but shortcoming is having relatively high expectations of master batch that this is made.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of fiber functional more lasting, water-fastness, reduce costs the preparation method with electromagnetic protection fibre in differentiation easy and simple to handle.
In order to achieve the above object, the preparation method of the electromagnetic protection fibre in differentiation that the present invention is designed, step is as follows:
The first step, drying of ceramic master batch: ceramic master batch is dried to processing, and dry temperature is controlled at 120 ℃, the dry time is 24 hours, the moisture content of dried ceramic master batch remains on 800ppm left and right, and wherein, ceramic master batch is formed by ceramic particle, dispersant and No. six section blend granulations of polyamide fibre, and the granularity of ceramic master batch is below 1～3um, and the addition of ceramic master batch is 0.3%, 0.6% and 1%;
Second step, the selection of No. six sections of polyamide fibre (PA6): the relative viscosity of No. six sections of polyamide fibre is 2.49, and fusing point is 219.6 ℃, and moisture content is less than 600ppm, and the addition of No. six sections of polyamide fibre (PA6) is 99.7%, 99.4% and 99%;
The 3rd step: filament spinning component and co-blended spinning: the impurity of bringing in elimination production process in assembly and the ceramic master batch that affects the super large of spinnability, more ceramic master batch and No. six sections of polyamide fibre are carried out to co-blended spinning;
The 4th step, cooling forming: the product that blend weaving is made carries out cooling processing, and cooling condition is that lateral blowing wind-warm syndrome is 22 ℃, wind speed is 0.45m/s;
The 5th step, dewing and oiling: the product of cooling forming is carried out to dewing and oiling treatment, make the oil applying rate of fiber be promoted to 1.6%～2.0%;
The 6th step, drawing-off is processed: for guaranteeing the distinctive high powerful feature of polyamide fibre, just must make fiber have the higher degree of orientation; For realizing this purpose, we improve drawing roller at melt from spinnerets pore is extruded speed in cooling forming process, to 4500m/min, allows fiber make macromolecular chain ordered arrangement obtain high orientation through the super drawing of excessively high speed;
The 7th step, reels and processes: the strand through high drafting feeds through draw-off godet the bobbin that the package of precise winding machine becomes constant weight and certain length;
The 8th step, long filament: the number of obtaining by winder winding is with the tow of myriametre or ten myriametres.
As preferably, in the 3rd step filament spinning component, the online of assembly is 100 order metal filter screen F30+F60 diamond dust, and off line is 200 order+325 order+30u nonwoven fabric metal filter screens, and the aperture of spinnerets is 0.3～0.32mm; When co-blended spinning, the temperature of screw rod is 240～265 ℃, and the temperature of spinning is 262 ℃, and the speed of coiling is for being less than or equal to 4500m/min.
In the 5th step, the finish of spin finishing is that Japanese F-6379HOY is oil solution dedicated.
According to the above, the preparation method of the electromagnetic protection fibre in differentiation of gained of the present invention, has the features such as easy and simple to handle, user's performance is good.
