The invention discloses a
sizing yarn technology utilizing a short
fiber sizing machine to produce DTY filament varieties and belongs to the technical field of
textile filament preparation. The
sizing yarn technology is characterized in that the speed of the short
fiber sizing
machine is adjusted to be reduced to be 20-25m / min, filament sizing agents with 4.5-5.5%
solid content are used for sizing, filament oil is filled into a
wax tank, antistatic agents are added in the filament sizing agents and the filament oil, the temperature of a baking
barrel is maintained at 150-155 DEG C, the filament is dried after oiling, the filaments are evenly placed in a telescopic reed after dry leasing, the number of filaments of each radial shaft is controlled to be 680-760 pieces / shaft, and each filament is provided with a dent on each shaft. According to the sizing
yarn technology, the short
fiber sizing
machine is used for realizing successful production of the DTY filament varieties, existing equipment does not need substantial improvements, investment is little, and filament varieties and short fiber varieties can all be produced normally. The sizing yarn technology makes up the blank that the short sizing machine cannot size filaments, and reduces waste of devices and raw materials through technological improvements.
