Description

一种羊毛针织物的静电消除加工方法
技术领域
本发明涉及一种羊毛针织物的静电消除加工方法,属于毛针织物生产技术领域。
背景技术
羊毛针织物具有柔软、舒适、透气和保暖性特点被广大消费者所喜爱,羊毛面料一般采用一定羊毛含量的混纺纱线编织而成,在加工和使用过程中易由于摩擦和感应而产生静电现象,积聚的静电电荷容易吸附灰尘并造成针织物产品在佩戴穿着时贴附纠缠在肢体上,产生不适感,会引起人体血液pH上升,血液中的钙下降,血糖上升等,而较高的静电压会对人体产生电机,易引起电气元件损伤甚至起火和爆炸。现有技术中公开的对于针织物产品的静电消除方法一般是采用抗静电喷雾或进行抗静电溶液浸泡处理,但这种处理方法的效果不持久,当空气干燥,具有导电性的水分含量下降时,电流流动受阻就会产生静电释放,导致羊毛针织物静电难以满足需求。
发明内容
本发明的目的是针对现有技术的缺陷,提供一种羊毛针织物的静电消除加工方法。
本发明是通过如下的技术方案予以实现的:
一种羊毛针织物的静电消除加工方法,其方法如下:
(1)前处理:将羊毛纱线置于抗静电溶液中浸泡后烘干进行前处理;
所述羊毛纱线的羊毛质量百分比含量为20~80%,所述抗静电溶液由双氢化牛油基二甲基氯化铵、异构十三醇聚氧乙烯醚、脂肪醇醚磷酸酯、酚醚磷酸酯和水按质量比4:3:5:1:(100~130)组成,浸泡时间为20~30min,浸泡温度为40~50℃,烘干温度为100~120℃,烘干时间为40~80min。
(2)给纱:将羊毛纱线和导电纤维送至针织机械的成圈编织区域;
(3)退圈:针织机械被配置为分别具有若干上针和下针的针盘和针筒,上针和下针上升将旧线圈从针钩移至针杆,上针超前下针1~4针起针,;
(4)垫纱:下针先下降,将羊毛纱线或导电纤维垫入针钩并随下针下将,旧线圈向上关闭针口,随后下针垫入羊毛纱线或导电纤维,所述导电纤维由纳米炭黑、二氧化镁、聚苯胺、聚噻吩和反式1,4-环己二胺按质量比1:1:(15~18):20:10熔融混纺而成;
(5)弯纱:上针和下针的下降使针钩接触羊毛纱线或导电纤维逐渐弯纱,并随下降延续至线圈成形,弯纱时下针先勾住羊毛纱线或导电纤维,并搁在上针针舌处进行弯纱,形成加长线圈,然后下针回升分纱给上针,上针向针筒中心运动进行弯纱;
(6)成圈:上针和下针进一步下降使旧线圈从针头上脱下,形成新线圈;
(7)牵拉:将旧线圈和形成的新线圈拉向上针和下针背后牵拉脱离编织区域,并循环步骤(2)~步骤(6)形成单路罗纹组织,以每1至N1-1路以羊毛纱线编织,每N1路羊毛纱线垫入一根或两根导电纤维,每N1+1路以导电纤维编织,作为织造循环进行编织形成针织面料,N1为2~5的整数,单路罗纹组织为(N2-1)+N2罗纹组织、N2+N2罗纹组织、或N2+(N2+2)罗纹组织,N2为2或3;
(8)后整理:将针织面料在175~180℃下置于开幅机上开幅定型,随后织接呈羊毛针织物。
本发明的有益效果为:
(1)采用羊毛含量20~80%的羊毛纱线,以季铵盐型阳离子表面活性剂、非离子型的异构十三醇聚氧乙烯醚和阴离子型脂肪醇醚磷酸酯、酚醚磷酸酯配伍,具有高渗透性和乳化性,吸附于纤维表面使限位表面平滑,可改善抗静电摩擦性;
(2)采用羊毛纱线与聚苯胺、聚噻吩和纳米炭黑、二氧化镁和式1,4-环己二胺配伍的导电纤维混合编织,在每N1路羊毛纱线垫入一根或两根导电纤维,织造循环进行编织形成针织面料,其消除静电在电晕放电的同时,诱导电荷聚集在导电纤维周围,进而泄漏入大地,抗静电作用更持久;
(3)每单路罗纹组织为(N2-1)+N2罗纹组织、N2+N2罗纹组织、或N2+(N2+2)罗纹组织,并开幅定型整理,适应羊毛纱线和导电纤维弹性,使整体尺寸稳定性好,不易脱散,表面平常光洁,不卷边,从而在整体上实现羊毛针织物的静电消除,有效防止静电的局部积聚,以便避免静电灰尘吸附和人体贴附,提高穿着舒适性和安全性。
