As shown in table 1, the polyamide fibre high speed spinning finish effect that after applicant finds to add nanometer additive prepared by embodiment is all better than comparative example, specifically:

Emulsion ordinary temperature stability, as shown in Table 1, finish prepared by comparative example 1 at 25 degrees c, will present milk shape after 7 days, have wall cling phenomenon to occur, less stable, affects it and uses and preserve; And finish prepared by embodiment 1 all presents translucent, occur that without any wall cling phenomenon there is extraordinary stability; Applicant also finds, then places the longer time, also there will not be wall cling phenomenon, and other embodiments then there will be a little wall cling phenomenon, therefore finish prepared by embodiment 1 has best implementation result;

As can be seen from Table 1, comparative example 1 has the generation of a small amount of breakdown of emulsion in high-temperature stability test, prove that this system emulsifying effectiveness is unsatisfactory, and from embodiment 1, after adding micro-nano additive and functional aid, the high temperature stability performance of spinning oil is better, and 80 DEG C, 8h demulsifying phenomenon does not occur.

Finish smoke point is one of important index, as can be seen from Table 1, the smoke point of comparative example 1 is 135 DEG C, and the smoke point of embodiment 1 is all greater than 144 DEG C, this may be because the adding of micro-nano auxiliary agent and fire retardant, micro-nano micella can be formed in finish, smooth agent and emulsifier package are overlayed in micelle volume, thus improve the temperature of being fuming of finish.

As can be seen from the above data, after adding micro-nano auxiliary agent, it well can act synergistically with functionalization auxiliary agent, on the volume basis increasing antistatic behaviour and flatness, gives finish better antibiotic property, anti-flammability and UV resistance performance.And finish is functional.

For checking the present invention is to the implementation result of fiber after oiling, carry out the test of following index:

Flame-proof treatment: flame-proof treatment: 45 DEG C of gradient methods, instrument regulation sample is with 45 DEG C of slant settings, and measure the severe degree that chinlon filament lights after-combustion, severe degree is the smaller the better, and speed is more slow better.

Anti-uv: ultra-violet radiation protection index (UPF) is that ultra-violet radiation makes skin reach to occur the threshold dose required time value of erythema and without the ratio of time value reaching same extent of injury during shielding, be worth larger, protection effect is better.Chinlon filament is neatly wrapped on cardboard, the ultraviolet protection function of test arrangement plane.

Flatness: coefficient of kinetic friction μ K is the important indicator of finish flatness, and μ K is less, and flatness is less.

Antistatic behaviour: volume resistivity ρ V is the index of finish antistatic behaviour, and ρ V is less, and antistatic behaviour is better.

Convergence: wet cohesive force represents the coherent of slurry oil silk on hygrometric state, its value is larger, and in representative, slurry oil convergence is better, and it is better to fall to starching performance.

Table 2 shows to add affects result on fiber after oiling after each function additive.
