宽幅竹纤维机织家纺面料的生产

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ 竹纤维具有良好的透气性和瞬间吸水性,以及天然抗菌抑菌、除螨、防臭和抗紫外线功能,是一种天然环保型绿色纤维。竹纤维织成的面料具有优良的着色性、悬垂性、耐磨性,既有很高的吸湿能力和较好的透气性,又有独特的回弹性能,其手感滑而细腻,丰满而挺括,因此备受消费者青睐。近年来,宽幅竹纤维机织家纺面料需求量逐年上升,但现有的常规竹纤维机织印染布普遍存在缩水率大、易起毛起球和起皱的缺点FZ/T 14012-2009《竹浆粘胶维印染布》标准中规定,优等品和一等品的水洗尺寸变化率分别为4.0%+1.0%-5.0%-2.0%,对织物起毛起球性能不考核。高缩水率和易起毛起球、起皱的性能,影响了竹纤维机织面料的使用性能。本文通过防缩整理、抗起毛起球整理、机械预缩等系列染整加工,降低竹纤维机织家纺面料的缩水率和提高抗起毛起球性,极大地提高其服用性能。主要的生产流程包括:卷染机前处理、卷染机染色、防缩整理、抗起毛起球整理、机械预缩等。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ 竹纤维是再生纤维素纤维,在纺丝时加了纺丝油剂,织造时上了较多浆料,必须通过前处理将其从纤维上去除,再进行染色和后整理。传统的前处理工艺通常在高温强碱条件下进行,处理效果虽好,但水电汽消耗量大,废水处理负荷重。随着环保、节能减排标准提高,酶退浆工艺和茶皂素双氧水工艺成为行业内的研究热点。

1.2.3 操作注意点

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (1) 进缸头子布可选用纯涤纶头子布,比染色布要宽,长度约30 m

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (2) 进缸布边尽可能要齐,最多相差lcm左右,以防产生色边。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (3) 设定起始点要在不影响上卷的情况下尽可能到头。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (4) 在不起皱的情况下张力越低越好,一般控制在7080 N,张力过大易产生条花或接头印。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (5) 染料要在化料桶充分化开后均匀放入染缸,以防产生色点和头尾缸差。

http://www.lokersuites.com/http://www.lokersuites.com/ http://www.lokersuites.com/1.3 防缩整理

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ 防缩整理是决定竹纤维织物尺寸稳定性的关键,价格低廉的N-羟甲基类树脂整理剂虽然能降低竹纤维织物缩水率问题,但不可避免地存在着甲醛释放的问题。无甲醛整理剂能有效避免织物上释放甲醛的问题,通过合理选择无甲醛整理剂,并采用松式预烘的防缩整理工艺,优化工艺参数,使得生产的缎纹组织的竹纤维织物成品的经纬向水洗尺寸变化率为-3.0%+1.0%

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ 1.3.3 操作注意事项:

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (1) 无甲醛整理剂选择。降低缩水率是选择无甲醛整理剂的一个重要条件;同时,还要考虑无甲醛整理剂对织物的弹性、色光、手感和断裂强度等的影响。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (2) 柔软剂的选择。棉织物经无甲醛整理后,手感一般都比较硬。为了改善手感,要在树脂整理浴中加入柔软剂许多阴阳离子柔软剂手感也较柔软但无法与催化剂共浴因此选用非离子柔软剂V-12

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (3) 严格控制工艺条件,确保缩水率、色光、手感和强度等指标达到设计要求。

http://www.lokersuites.com/ http://www.lokersuites.com/http://www.lokersuites.com/在保证抗起毛起球的前提下,尽量减少抗起毛起球助剂的用量,用量过多会影响织物手感。

http://www.lokersuites.com/ http://www.lokersuites.com/http://www.lokersuites.com/1.5.1 机械预缩工艺

http://www.lokersuites.com/http://www.lokersuites.com/ http://www.lokersuites.com/织物均匀给湿,含湿率8%12%,橡胶毯承压辊蒸汽压0.10.2MPa,呢毯锡林蒸汽压).10.2MPa,控制预缩率3%5%,布速4050m/min

http://www.lokersuites.com/http://www.lokersuites.com/ http://www.lokersuites.com/1.5.2 操作注意事项

http://www.lokersuites.com/ http://www.lokersuites.com/http://www.lokersuites.com/(1) 机械预缩整理前要先测定织物的缩水率,以便更好地调整承压辊压力,将织物在预缩整理后的缩水率控制在规定范围内。

http://www.lokersuites.com/http://www.lokersuites.com/ http://www.lokersuites.com/(2) 织物在潮湿状态下才具有一定的可塑性,通过给湿辊给湿,布面湿度控制在10%20%布面的湿度高则预缩率也高,但易产生表面极光。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (3) 预缩时要控制进布张力,以织物不起皱为原则,不宜过紧,以免抵消预缩作用。

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (4) 预缩毯受压量应根据预缩前缩水率大小控制停车时不得受压停车以免烫伤橡胶毯面

http://www.lokersuites.com/http://www.lokersuites.com/http://www.lokersuites.com/ (5) 织物加工结束后关闭进汽阀打开排水阀全机保持低速运转待蒸汽压力下降后通冷水入承压辊冷却,待橡胶毯、毛毯冷却后停车。
