| 摘 要： | 采用POY-DTY工艺路线生产105 dtex/72 f细旦DTY竹节丝,探讨了其加工工艺条件。生产实践证明:丝条停留在热箱的时间为0.3~0.4 s,加工速度在420~450 m/min之间,第一热箱温度控制在(230±3)℃以内,成品丝会有较好的镂空感。把105 dtex/72 f的竹节丝牵伸比控制在1.25~1.27之间,同时选择速比D/Y在2.25,生产状况和成品丝物理性质较好。同时为降低残余扭矩,提升成品织造效率,第二热箱温度为210~220℃,网络压力设置为0.14~0.16 MPa。

| Abstract: | 105 dtex/72 f fine denier DTY slub yarn is produced by POY-DTY process, the processing conditions is discussed. The production practice shows that when the stay time of yarn in hot box is 0.3~0.4 s, the processing speed is 420~450 m/min, the temperature of the first heat box is(230±3) ℃, the finished yarn will have the better sense of hollowing. When the drawing ratio is controlled at 1.25~1.27, the D/Y is chosen 2.25, the production status and the properties of finished product are better. In order to reduce the residual twist and improve weaving efficiency of finished product, the temperature of the second hot box is 210~215 ℃ and the interlaced pressure is 0.13~0.16 MPa. |
