In summary, the present application includes at least one of the following beneficial technical effects:

1. the integrative forming can strengthen the apparent structural strength of fibre body at this external fibre sand grip of fibre to and then improve the rigidity of fibre body to this makes fibre body be difficult to take place bending deformation, and the bulk cellosilk loose nature is better. Therefore, when the clothes are acted by a human body, the clothes are not easy to be stressed and compressed to become compact, and can still keep better fluffiness, so that the air permeability of the clothes is improved;

2. polyester material is extruded into in the feed port by the extruder body, then is extruded from the logical groove of shaping and the vice groove of shaping simultaneously to this can the shaping fiber body and the fibre sand grip that set up of an organic whole.
