Abstract
The present invention relates to a technique of propylene copolymers. The permanent antistatic dyeable polypropylene fibre of the present invention comprises 2 to 8% of antistatic mother particle, 4 to 15% of dyeable mother particle and 77 to 94% of particle material of polypropylene according to the weight percentage. The permanent antistatic dyeable polypropylene fibre has permanent antistatic performance and is dyeable; the permanent antistatic dyeable polypropylene fibre can be spun into polypropylene fibre yarns to be used for spinning; the fibre flexibility is obviously improved and the volume specific resistance reaches M*10<6>. cm; in addition, the energy saving is obvious in the process of spinning.
Description
The invention belongs to the technical field of the copolymer of propylene.
Polypropylene fibre has wicking, lead moist strong, light weight, acid and alkali-resistance, anticorrosive, thereby in industry and decoration field, obtained using widely, but because the compound with regular structure of polypropylene fibre, not polar functionalities, can not resemble and dye the terylene, the volume resistivity of polypropylene fibre is very high, reaches M * 10
16Cm, friction can produce serious static gently, has therefore influenced the application of polypropylene fibre in textile industry and clothing field.The clear 61-85298 of Japan's patent discloses a kind of propylene series polymer, it is to add series of phosphate compound and antistatic additive in the propylene series polymer, make it to produce the anlistatig polypropylene chip of energy, but the composition of making can only be done extrusion-molded product, manufactured goods such as hollow forming product, film, thin plate, and can not be used for spinning.Make textile raw material.
The purpose of this invention is to provide a kind of durable antistatic that both had, stainable again polypropylene fibre, and also can make the polypropylene fibre of textile raw material.
This permanent antistatic dyeable polypropylene fibre comprises polypropylene, antistatic master granule and can dye master batch, and by weight percentage, antistatic master granule is 2-8%, can dye master batch is 4-15%, polypropylene granules is 77-94%.
Antistatic master granule of the present invention adopts ethoxy alkylamine, higher aliphatic and the composite antistatic additive of silica (" plastic additive handbook, the 643rd page), the powder polypropylene of melt index MI=8-30, and composite by weight percentage antistatic additive accounts for 10-50%, and the powder polypropylene accounts for 50-90%.
Can dye master batch and comprise dimethyl terephthalate (DMT) (DMT), ethylene glycol (EG) and poly-adipic acid fourth diester (A), and it is DMT: EG: A=1: (2.0-3.0): (0.005-1.0) in molar ratio.
In permanent antistatic dyeable polypropylene fibre, polypropylene granules accounts for the 82-90% of gross weight, can dye the 6-12% that master batch accounts for gross weight.Antistatic master granule accounts for the 4-6% of gross weight.
Make the method for permanent antistatic dyeable polypropylene fibre of the present invention, be middlebrow method, adopt add blending method, by weight with antistatic master granule with can dye master batch and add in the polypropylene granules, after mixing, through common screw extruding spinning machine blend melt spinning.Not only permanent anti-static but also stainable polypropylene fibre can have been produced according to a conventional method.
Owing in polypropylene granules, be mixed with antistatic master granule, and the fusing point of antistatic master granule low (120 ℃-150 ℃), melt index height (MI=30-90), so antistatic master granule and polypropene blended spinning, the polypropylene fiber volume resistivity of spinning is very little, can reach M * 10
7Ω cm (M is less than 10 number greater than 0), adding can be dyed master batch, make spun polypropylene fiber to dye, and the addition of antistatic master granule is low, and effect is remarkable, and is easy to use, and the flexibility of fiber has clear improvement.
Below in conjunction with embodiment the present invention is elaborated.
Table 1
As can be seen from the above table, along with the increase of antistatic master granule addition and the increase that can dye the master batch addition, the volume resistivity of polypropylene fibre is index law and descends, the content of antistatic master granule is greater than after 7%, the speed that volume resistivity descends reduces, along with the increase that can dye master batch content, dye-uptake is also increasing.
Table 2
Table 3
Table 4
Embodiment from above table as can be seen, antistatic master granule helps the absorption of dyestuff, dye-uptake improves, along with the increase that can dye the master batch addition, dye-uptake increases, when can dye the master batch addition greater than 14% after, dye-uptake no longer changes basically, COLOR FASTNESS is irrelevant with the size that can dye the master batch addition.
When producing this antistatic dyeable polypropylene fibre; with antistatic master granule, can dye master batch and polypropylene and pour in the ratio in the foregoing description and mix in the grain machine; mix after common screw extruding spinning machine blend melt spinning, produce according to a conventional method and not only have permanent antistatic but also stainable polypropylene fiber.Be spun into pure polypropylene fiber yarn No. 20 with this polypropylene fiber, be made into cotton lid polypropylene fibre and weave cotton cloth polypropylene fiber and cotton blend fabric, pure polypropylene fibre knitted cloth.The electrostatic pressure that records pure polypropylene fibre knitted cloth is 32 volts, and 1.3 seconds half-life, pleasant softness obviously is better than the normal polypropylene fabric.And at same equipment, under the identical process conditions such as same melt pressure, the antistatic dyeable polypropylene fibre staple fibre of spinning same size, energy-saving effect is remarkable, sees the following form:
This shows this permanent antistatic dyeable polypropylene fibre, both antistatic, can dye, energy-conservation in process of production again, therefore have high promotional value.
