Abstract
A composite spinning method for preparing superfine (dpf less than 1 dtex) functional composite fiber features that the mixture of polyamide chips and organic bacteriostat M particles is used as core and the mixture of polypropylene chips and inorganic bacteriostat HN particles or far infrared particles is used as coating, and includes such steps as spinning with dual-screw and shaped hole spinneret assembly, winding, stretching, thermal shape fixation, finishing and stripping to obtain the functional composite superfine fibre. Its advantages are simple technology, good hand, and good antibacterial, deodouring. Warming and health-care functions.
Description
The present invention relates to a kind of method that adopts composite spinning technology manufacturing function type superfine composite polyamide-polypropylene fibre and fabric.
In the prior art, antibiotic or the far IR fibre of relevant one-component, the report that splits release composite ultrafine fiber are a lot of, but thin dawn, super fine denier functional fibre majority are to adopt conventional one-component high speed spinning method, but adopt conventional high speed spinning method to produce thin dawn, super fine denier functional fibre because the adding of functional mass makes that the spining technology difficulty is big, consume high, the technology controlling and process complexity is difficult to form large-scale industrial production.Abroad also have to utilize and split release composite spinning method and produce antibacterial polyester-polyamide compound fibre, its deodorizing antibiotic agent is with polyamide blended, splits the method for release function composite fibre and does not appear in the newspapers as yet but cortex and sandwich layer add the production of function composition simultaneously.
Purpose of the present invention, be to solve and use conventional high speed spinning method to spin thin dawn, the high problem of super fine denier functional form polypropylene filament yarn technical difficulty, and a kind of functional superfine composite polyamide-polypropylene fibre spinning technology is provided, the technology of employing is simple, reliable, but large-scale industrial production.
In order to achieve the above object; the present invention has adopted following technical scheme: adopt polyamide section and organic bacteriostatic agent-M master batch blend composition make core; the blend composition of polypropylene chip and inorganic antiseptic HN master batch or far-infrared matrix is made skin; the weight ratio of core-skin is 50～80: 50～20; with twin-screw and the spinning of profiled holes composite spinneret pack, after coiling, drawing-off, HEAT SETTING arrangement, peel off the functional form composite ultrafine fiber.
The present invention's technical scheme preferably can be: the polyamide core fibre is that the addition of organic bacteriostatic agent is 0.02～0.1wt%, again through melt spinning by polyamide section and the master batch blend that contains organic bacteriostatic agent of alkylamide and imidazolines mixture; The polypropylene sheath fiber is by polypropylene chip and contains Ag ion nanometer grade inorganic antibacterial agent blend that the addition of inorganic antiseptic is 0.2～0.5wt%, again through melt spinning.
The present invention's technical scheme preferably also can be: adopt * type or rice font hole composite spinneret pack to make the composite fibre of respective cross-section in the spinning, peel off then the function composite ultrafine fiber.The interfacial structure of described composite spinneret pack distribution plate is stable, and the profiled composite fibre that makes is easy to peel off, and the function composite ultrafine fiber performance that obtains after peeling off is good and applicability is strong.
The present invention's technical scheme preferably can also be: the polyamide core fibre is that the addition of organic bacteriostatic agent is 0.02～0.1wt%, again through melt spinning by polyamide section and the master batch blend that contains organic bacteriostatic agent of alkylamide and imidazolines mixture; The polypropylene sheath fiber is that the addition of far infrared agent is 3.0～6.0wt%, again through melt spinning by polypropylene chip and the master batch blend that contains the nanoscale far infrared agent of Al, Si, Zr, Ti ion.
The total fiber number of the functional superfine composite polyamide-polypropylene fibre that makes with said method is: 55.6dtex～166.7dtex, the fiber number of peeling off the back polyamide fiber is that the fiber number of every rhizoid is: 0.46～3.47dtex, the fiber number of polypropylene fibre is that the fiber number of every rhizoid is: 0.19～0.93dtex.
The functional superfine composite polyamide-polypropylene fibre that makes with said method, when weaving dyeing and finishing, adopt the finishing technique of weaving of polypropylene fibre, the dyeing of polyamide makes polypropylene peel off into the function superfine fibre from polyamide, make fabric have submissive comfortable feel, stronger single face is led sweat and anti-bacterial anti-foul function or insulation, health care, the bacteriostatic deodorizing function, antibacterial composite fibers is to Escherichia coli, the fungistatic effect of staphylococcus aureus is good, record the average bacteriostasis rate that contact 24h after all greater than 95% with reference to GB15979-1995 (appendix B-product antibacterial with bactericidal property and stability test method) and disinfection technology standard (third edition) with the vibration flask method by Hunan Hygienic ﹠ Epidemic Prevention Station, adopting IRE-1 type infrared radiometer to record the far infrared composite fibre under 50 ℃ by Shanghai Inst. of Technical Physics, Chinese Academy of Sciences is 84% at the far infrared transmissivity of 8～25 μ m.
Compared with prior art, the present invention has following tangible advantage:
1, the technology of this manufacturing technology employing simply, reliably, easily realizes the big production of industrialization.Adopt composite spinning technology production function composite ultrafine fiber, the problem that solved and used the conventional high speed spinning method spinning thin dawn of functional form, the superfine Denier fibre technical difficulty is big, consumption is high, is difficult to form industrialized production;
2, the functional fibre of this manufacturing technology production adopts two kinds of different functional agglomerates to be scattered in respectively in the polymer of skin, core, it is respond well, can overcoming organic bacteriostatic agent-M, to add in the polypropylene washability to poor, inorganic antiseptic, far infrared agent influence shortcomings such as fibre property, spinnability difference, have also solved the shortcoming of far IR fibre antibacterial effect difference simultaneously;
3, color depth can reach moderate depth on the function composite ultrafine fiber of this method spinning, and fiber and fabric are both soft comfortable, has good single face again and leads sweat and anti-bacterial anti-foul function or insulation, health care, bacteriostatic deodorizing function.
