Description
Technical field
The present invention relates to a kind of manufacturing approach of tangerine lobe type composite fibre.
Background technology
Tangerine lobe type composite fibre is a kind of sliver type composite fibre that is made up of two kinds of performance different polymer, and its cross section is made up of the sliver of similar " orange " shape.Certain compatibility is arranged guaranteeing normally carrying out of spinning and back process between two kinds of performance different polymer, but on performance difference to some extent again, can in fabric treatment procedure, the method through chemistry or physics composite fibre be split into superfine fibre.Adopt the fibre section of this form, after peeling off, can obtain " wedge " type superfine fibre, every fiber has 3 place's wedge angles, and there is fabulous dirt-removing power at the edge that it is sharp-pointed to dust, greasy dirt, and it is highly beneficial to be used as cleaning wiping cloth.This tangerine lobe type composite fibre is divided into kinds such as 6+6 or 8+8 usually, promptly forms tangerine lobe type by 6 lobes (or 8 lobes) PET and 6 lobes (or 8 lobes) PA6 space.The weight ratio of two kinds of components can be 15/85~85/15. finally can obtain the superfine fibre that line density is 0.1~0.5dtex.
