The preferred version that the present invention prepares the linear chinlon 6 filament of double wave wave is: chinlon 6 section relative viscosity is 2.40~2.70; Spinning temperature is 260 ± 2 ℃; The heat roller temperature of heat setting process is 125 ℃~145 ℃; The winding speed 4000 m/min~4500m/min of coiling and molding technique.
Technical solution of the present invention also comprises the linear chinlon 6 filament of a kind of double wave wave preparing as stated above.Its fiber number is 1.5dtex~5.0dtex; Fracture strength is 4.0cN/dtex~5.0cN/dtex, and elongation at break is 40%~50%.。
Compared with prior art, the invention has the beneficial effects as follows:
The multi-functional characteristics such as the capillary wicking effect that 1, the prepared linear chinlon 6 filament of a kind of double wave wave of the present invention has that specific area is large, gloss is soft, dyeability is good, moisture absorption, moisturizing are ventilative.
2, the chinlon 6 filament that the present invention makes and fabric thereof possess that voidage is large, softness, light weight, wide coverage and warmth retention property good, also there is good moisture absorption ventilative and lead the special efficacies such as moisture retention and resilience that wet.
3, the present invention makes chinlon 6 filament and fabric thereof have the future develop that production cost is low, wearability good and superiority of effectiveness is obvious and wide.
