Description

高强竹天丝家纺面料及其生产方法
技术领域
本发明属于纺织技术领域,具体而言,涉及一种高强竹天丝家纺面料及其 生产方法。
背景技术
我国是纺织品生产大国,也是巨大的纺织品消费市场。现今,人们追求绿 色消费、返璞归真的心声越来越强烈。为了顺应时代的发展,满足消费者对家 纺面料高品质的需求,企业需要不断采用新技术、新工艺、新原料,开发出高 技术含量的产品,以迎合市场需求,提高企业的核心竞争力。
竹纤维是近年来国内研究的热点。但是,竹浆纤维面料存在的水洗缩率较 大、尺寸稳定性差的缺陷,因此,人们致力于开发一种功能优异的竹纤维,使 其具有较高的强力、较小的洗涤缩率。
竹纤维的原料是竹子。竹子主要由纤维素、木质素、果胶和多戊糖等组成, 纤维素含量为40%~50%,木质素含量为20%~30%,多戊糖含量为16%~21%, 另外还有1%~3%的灰分。根据竹纤维的加工方法的不同可以分为:竹原纤维 和竹浆纤维。将竹材通过物理机械方法提取天然纤维素成分,直接得到竹原纤 维。其中纤维素含量在95%以上,线密度为4.4~6.6dtex,长度为2~36cm,平 均长度为8cm。采用化学方法将竹材制成竹浆粕,将浆粕溶解制成竹浆溶液, 然后采用粘胶或Tencel纤维的纺丝工艺流程,通过湿法纺丝制得竹浆纤维。竹 浆纤维的主体长度为85mm和38mm,线密度为4.85dtex和1.67dtex。竹浆纤 维不仅具有棉、木浆纤维所有特性,因其特殊的纤维素分子结构,使纤维横截 面布满了大大小小的椭圆形空隙,可以在瞬间吸收并蒸发大量的水分,其吸湿 性、透气性等远远超过棉、木浆纤维,夏季使用感觉自然凉爽,冬季使用柔软 滑爽,尤其具有抗菌抑菌性,适用于医疗卫生、纺织等领域,被誉为新一代绿 色环保纤维。
竹天丝是利用天然竹子为原料,采用天丝(Tencel)纤维的纺丝工艺流程 生产的一种新型再生纤维竹纤维。
天丝产品良好的性能颇受人们的欢迎,但是由于每年生产天丝的原料—— 桉树的数量有限,导致天丝纤维的原料非常紧张,急需寻找天丝原料的替代品。 竹天丝纤维的成功研发,解决了天丝原料紧缺的现状。
竹天丝纤维产业的发展突破了传统的竹材应用领域,丰富了竹文化的内涵, 符合时代发展潮流,具有良好的市场发展前景。

本发明半丝光处理既可以保证面料丝光后的得色率,同时在保证强力损伤不 大的前提下增强了尺寸稳定性。
本发明成品面料的主要指标检测情况:
具体实施方式
下面结合具体实施例对本发明作进一步说明,以使本领域的技术人员可以 更好的理解本发明并能予以实施,但所举实施例不作为对本发明的限定。
织造生产工艺流程如附图1所示;
染整工艺流程:
坯布翻缝——烧毛——酶退浆——煮练——漂白——半丝光——染色—— 柔软整理——拉幅定型——预缩——成品
整经、浆纱工艺
整经
整经时纱线的张力对织造工序及成品质量有着至关重要的影响。整经时既 要考虑单纱张力,又要考虑片纱张力。片纱张力不匀会造成开口不清,经轴上 的张力差异不会在浆纱工序及织造工序消除,对产品的平整度、外貌风格及布 边的好坏都会有影响,因此不论对单纱张力差异还是片纱张力差异都应该引起 高度的重视。
本发明采用贝宁格分批整经机,整经根数890根,卷绕线速度600m/min。
浆纱
浆纱的质量直接影响纱线的可织性,所以对浆纱的质量必须按时检验,及 时控制。由于PVA存在很多缺点:①难以生物降解;②用PVA上浆,其退浆 困难等。鉴于上述缺点,在本项目产品的织造过程中,采用无PVA上浆,顺利 织造高强竹天丝家纺面料。
浆料配方为:定积690升,马铃薯淀粉75kg,酯化淀粉25kg,丙烯酸25kg, 蜡片3kg,抗静电剂3kg,防腐剂0.3kg,柔软剂2块。浆纱上浆率17%,回潮 率10%,伸长率≦0.8%。
织造
该品种在喷气ZAX9100织机上织造。在织造过程中,经过反复试验摸索, 确定的主要上机工艺参数设置如下:开口时间310°,预定张力350kg(约3500N), 后梁高度20mm。同时,加强车间温湿度的管理,改善织造时所需的生产环境。 温度控制在25±2℃,相对湿度为76±3%。
布机车速450r/min,织造效率75%~80%,十万纬经停7次,纬停24次, 是宽幅高支高密竹纤维面料织造的里程牌。
染整工艺
通过合理有效的后整理工艺,对于提高竹纤维面料的外观和内在品质至关 重要。
染整工艺流程:
坯布翻缝——烧毛——酶退浆——煮练——漂白——半丝光——染色— —柔软整理——拉幅定型——预缩——成品
烧毛
由于坯布表面有一部分短茸毛,如果不烧毛或者烧毛不净,既影响布面效 果,又容易在印染加工中由于茸毛粘结产生染色不匀、掉色而造成疵病。
在保持面料风格、不引起面料损伤的前提下,兼顾合理调节烧毛工艺参数, 使产品达到一定的布面光洁度。烧毛工艺:两正两反,车速100~120m/min, 烧毛质量达3~4级。
酶退浆
在织造前,经纱需要经上浆处理,使纱中的纤维粘着抱合起来,并在纱线 表面形成一层薄膜,以便于织造。退浆是前处理的基础,通过处理,可以去除 坯布上大部分的浆料以及部分杂质,以利于煮练等后序加工。
由于竹纤维不耐强碱,故本项目采用宽温幅退浆酶2000L对坯布进行退浆 处理。该退浆工艺作用条件缓和,不会损伤纤维素纤维,并且作用效率高。由 于酶对坯布上的淀粉完全分解需要一定的时间,保温堆置可以使酶对淀粉进行 充分水解;淀粉浆料经过淀粉酶水解后,仍然粘附在坯布上,需要经过水洗才 能去除完全。
退浆工艺:
煮练
竹纤维中由于天然色素的存在,如果处理不好,既使白度均匀性变差,又 影响染色性能。煮练结束后,要经过充分的水洗,防止浆料等重新沾污坯布表 面。
煮练工艺:
漂白
为了进一步提高面料白度,防止泛黄;同时,由于该面料拟染成浅色系, 故在煮练后进行漂白处理至关重要。
漂白工艺:
半丝光
考虑到浓碱对竹纤维的强力损伤以及扩幅困难的影响,采用半丝光处理, NaOH浓度为155~165g/L,既可以保证面料丝光后的得色率,同时在保证强 力损伤不大的前提下增强了尺寸稳定性。
染色
染色时染料的选择应该根据面料色泽要求、牢度要求进行认真的筛选,提 高色牢度。
本发明选用B型活性染料对竹天丝面料进行浸染。染液中加入定量的促染 剂NaCl和纯碱Na2CO3,同时,加强对染色时间、染色温度的控制。
染色时,染料首先通过范德华力和氢键吸附在竹纤维表面,并向纤维内部 扩散。在碱性条件下,活性染料与纤维发生化学反应形成共价键结合而固着在 纤维上。最后,通过皂洗将残余染料洗除,减少纤维表面浮色。
后整理
柔软整理的主要作用在于改善面料的手感,使触觉柔软滑爽,进一步提高 其舒适性。
该项目所用柔软剂为非离子型氨基硅柔软剂,它能显著降低纤维和纱线间 的摩擦系数,赋予面料独特的平滑柔软手感,并且具有良好的热安定性和耐洗 涤性。
由于在拉幅机上进行,同时定幅,去除了面料表面褶皱。其工艺参数为: 氨基硅柔软剂10g/L,轧余率65%~75%,车速35~50m/min,PH值5~7。
采用三辊橡胶毯预缩机进行预缩整理,保证面料的经向缩水要求,进一步 提升面料的手感。车速控制在50m/min左右。
成品检验打卷
按照国家标准检验检测、成品打卷。
所产品坯布规格:106"高强竹天丝60×高强竹天丝60 173×130 5枚3 飞缎纹
成品规格:100"高强竹天丝60×高强竹天丝60 183×132 5枚3飞。
