It is to be limited by every technical characteristic of associated dependent claims and the combination of technical characteristic that the present invention is advantageously improved
Fixed.
The specific advantages that the present invention has are, yarn is immediately subjected to strengthen heat treatment after drawing-off, and this is beneficial to reduce
Internal stress in the molecular structure of long filament.In like fashion, yarn is guided on the surface of seal wire rolle rsleeve of three heating,
Between seal wire rolle rsleeve, the latter surrounds short slack strand.On the one hand it is thus possible to carry out very on the circumference of seal wire rolle rsleeve
Stable yarn guiding, on the other hand, does not have what substantive cooling stage occurred in slack strand freely to guide in length of yarn.Especially
In order to produce yarn with the count of yarn by a relatively large margin, free slack strand is limited in total contact length in lax period
One ratio.In like fashion, can produce in optimal yarn qualities of lax period and be more than pine in the total contact length for heat treatment
The multiple of the free length of yarn of relaxation section is in 3 to 7 region of scope.Three seal wire rolle rsleeves are the composition portions of contact length
Point, the surface temperature of three seal wire rolle rsleeves is in 120 DEG C to 250 °C of scope, preferably 150 DEG C to 250 DEG C, depending on yarn
