Wherein being expressed as of spinnability：Below broken end number of times 1 time in the case of spinning in 12 hours is zero for zero, 2～3 times
～△, 4～6 times for △, more than 6 times be ×.The spinnability of zero～more than △ calculate good it is allowed to scope.
Spinning preparation is carried out according to the nylon composite that the content in table 1 can be seen that using invention provides
Nylon fiber, spinning temperature is higher, draft speed faster in the case of broken end number of times seldom, the combination of the present invention offer be described
Thing has a good spinnability, and the filament number obtaining be the nylon fiber intensity of 20～40d and percentage elongation all higher hence it is evident that
Better than comparative example.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
