| Abstract: | According to the technical requirement of staple fibers for paper making felt,nylon 66/high-intrinsic voscosity polyester (PA66/PET) composite staple fibers was prepared with nylon 66(PA66) as the sheath and high-intrinsic viscosity polyester (PET) as the core.The production process was discussed.The results showed that the produced 33 dtex×76 mm staple fiber for paper making felt was fairly good in quality when the process conditions were as followed:PA66/PET mass ratio of 60/40,spinning temperature 298℃,the first draw ratio 3.8,the second draw ratio 1.15,the first drawing temperature 85℃,the second drawing temperature 100℃,cross air blow temperature 18℃,air speed 1.0 m/s. |
