针对化纤欧根纱比较硬、不亲肤、穿上会感觉扎、应用领域受限的缺陷,研制出PET-PTT复合分纤母丝设备。介绍了复合分纤母丝设备参数及设计要求,讨论了复合比、牵伸比、卷绕张力、侧吹风温湿度、纺丝温度等生产工艺。用该设备生产的PET-PTT复合分纤母丝是带有自卷曲的弹性纤维,其质地柔软,膨松性、回弹性、尺寸稳定性好。
In view of chemical organza yarn is relatively hard, not skin-friendly, put on the feeling will tie, the application of the limited defects, developed a PET-PTT composite fiber distributor equipment. The equipment parameters and design requirements of composite fiber division busbars are introduced. The production processes of compound ratio, draft ratio, winding tension, temperature and humidity of side blowing air and spinning temperature are discussed. The PET-PTT composite fiber-dividing mother yarn produced by this equipment is a flexible fiber with self-crimping, soft, bulky, resilient and dimensionally stable.
