Description
技术领域
本发明属于纺纱技术领域,具体涉及一种再生有色涤纶消光缝纫线的生产方法。
背景技术
涤纶缝纫线也称为高强线,具有强度高、耐磨性好、缩水率低、吸湿性及耐热性好,耐腐蚀、不易霉烂、不会虫蛀等优点而被广泛地应用于棉织品、化纤和混纺织物的服装缝制中。此外,它还具有色泽齐全、色牢度好、不褪色、不变色、耐日晒等特点。在服装制作中,缝纫线起着举足轻重的作用,用于缝合各种服装材料,具有实用与装饰双重功能。缝纫线质量的好坏,不仅影响缝纫效果及加工成本,也影响成品外观质量。再生有色涤纶短纤维可用于下游纱厂进行纺纱织布,符合纺织化纤行业鼓励发展的新型工艺路线。随着国内涤纶短纤开发技术的发展,差别化彩色高附加值的化纤产品的开发生产成为众多化纤制造厂家发展的方向大。2008年10月22日CN200810123796.4公开了一种有光涤纶短纤的生产方法,使缝纫线光泽度好,以此来制备有光涤纶缝纫线。而消光缝纫线是光线向不同方向漫射,使纺制的缝纫线光泽变暗,起到消光作用。2018年11月23日中国专利CN201810879056.7公开了一种吸湿涤纶缝纫线的制备方法,采用连续性复合单丝制备,但难以实现吸湿效果,且不能实现消光效果。目前,鲜有涤纶消光缝纫线的相关技术及产品公开。作为本领域技术人员,亟待开发新型的一种再生有色涤纶消光缝纫线的生产方法。
发明内容
本发明的目的是针对现有的问题,提供了一种再生有色涤纶消光缝纫线的生产方法。
本发明通过以下技术方案实现:
一种再生有色涤纶消光缝纫线的生产方法,除常规的透明涤纶短纤维开清棉、梳棉、并条步骤后,还包括如下步骤:第一步、粗纱:将熟条进一步拉长拉细,得粗纱;第二步、细纱:将粗纱进一步牵伸并通过加捻和卷绕纺成管纱;第三步、络筒:将容量小的管纱络筒成大卷装筒子纱;第四步、并纱:将筒子纱进行并和成股,其中车速500-600米/分钟,并和股数2-3股;第五步、倍捻工序对并筒进行加捻,做成倍捻筒子线;第六步:丝光,将倍捻筒子线在丝光机套纱辊上张紧,并在张紧张力下转动辊筒,使纱线浸丝光液,然将纱线从松弛的套纱辊上取下使纱线无张力下再浸丝光液,再通过热水冲洗、冷水冲洗得丝光后纱线;第七步、烧毛:丝光后纱线用温度为900℃,车速为600m/min气体烧毛机烧毛;第八步:上蜡乳润饰浆;第九步、蒸纱:蒸纱机60℃,保温20min,即得。
进一步的,所述呋第一步其中总牵伸倍数4.68-12.77,前罗拉转速150-350r/min,捻度18.6-81捻/米,锭速1200r/min。
进一步的,所述第二步总牵伸倍数9.82-15.13,后牵伸倍数1.057-1.957前罗拉转速150-270r/min,锭速7500-15500r/min。
进一步的,所述第三步的自动络筒机车速900-1600m/min,纱库式喂入,适用捻向Z捻和S捻,采用空气捻接器。
进一步的,所述第五步倍捻机:锭数144,锭速10000-12000r/min,捻向Z或S,卷取速度最大60米/分卷绕动程152mm,锭距225mm。
进一步的,所述第六步的丝光液含NaOH230~250g/L、乙二醇单丁醚磷酸双酯钠盐10~30g/L,并且丝光液温度20~30℃,其中倍捻筒子线先在张紧张力下浸丝光液10s,再取下无张力下浸丝光液20s,再在套纱辊上张紧张力下浸丝光液10s,再取下无张力下浸丝光液20s,再在套纱辊上张紧张力下40~50℃热水洗2遍、15℃冷水洗3遍,其中张紧张力。
进一步的,所述第八步用浆纱机上蜡乳润饰浆,其中浆纱机车速25m/min,伸长率1~1.5%,回潮率3.5~4%,米糠蜡40~50份、12-羟基硬脂酸6~8份、吗啉6~7份、质量分数10%氢氧化钠水溶液20份、90℃热水400份,把米糠蜡与2-羟基硬脂酸混合,加入吗啉,混匀,加热至95℃,加入氢氧化钠水溶液搅拌至胶浆状,再加入热水,搅拌至室温,即得蜡乳润饰浆。
本发明的有益效果:
本发明公开的再生有色涤纶消光缝纫线的生产方法,光泽柔和,消除了再生有色涤纶纤维表面的光泽,避免了极光的存在,使缝纫线具有毛织物般柔和光泽;经过丝光、烧毛、上蜡乳润饰浆的处理使纤维表面形成少量的微坑,使织物具有良好的皮肤触感和细腻干爽性能,且微孔的产生可以增强光的漫散射,缝纫线不需染色,满足了各种颜色服装加工缝制的需求,减少了后加工过程中染整环节的污染,具有节能、环保、且色牢度高的优点。
本发明相比现有技术具有以下优点:
本发明公开的再生有色涤纶消光缝纫线的生产方法,生产的有色涤纶消光缝纫线不但具有普通涤纶短丝产品的特点,而且具有纱线缝纫强度高、纱线色牢度好、处于湿态时也不会降低强度、缩水率小的特性。缝纫线还具有耐高温、光泽度好等特性,并且该类产品缝制的线迹始终保持平整美观,无皱缩,缝纫线不需染色,满足了各种颜色服装加工缝制的需求,减少了后加工过程中染整环节的污染,具有节能、环保、且色牢度高的优点。同时有色涤纶缝纫线用途广泛,可用于棉织物、化纤织物与混纺织物的服装缝制,特制的涤纶缝纫线还是鞋帽皮革行业的优良用线。
具体实施方式
下面用具体实施例说明本发明,但并不是对本发明的限制。
