Description

一种仿聚酰胺纤维的聚酯纤维裤袜
技术领域
本发明涉及裤袜技术领域，特别涉及一种仿聚酰胺纤维的聚酯纤维裤袜。
背景技术
聚对苯二甲酸乙二醇酯(PET纤维或聚酯纤维)纤维自问世以来，具有断裂强度和弹性模量高，回弹性适中，热定型优异，耐热耐光性好以及耐酸耐碱耐腐蚀性等一系列优良性能，且织物具有抗皱免烫，挺括性好等优点，广泛应用于服装、家纺等领域。聚酯纤维作为最广泛使用的化学合成纤维，由于具有良好的强度和耐光、耐热、耐酸碱性能，以及优良的加工性和易纺性，在服装、家纺、装饰和产业用领域得到广泛应用。然而，由于涤纶分子结构排列紧密，强度偏高，柔软度偏低，且缺少能直接被染色的极性基团，染色性能差，使其面向高端服装的应用受到阻碍。另一方面，聚酯纤维的吸湿性较差，也影响了其应用。
锦纶学名聚酰氨纤维，又被称之为尼龙，是中国所产聚酰胺类纤维的统称。强度高，耐磨性，回弹性好。锦纶吸湿性和锦纶有热定型特性，能保持住加热时形成的弯曲变形。锦纶面料以其优异的耐磨性著称，并且质地轻薄，所以它是运动衣、游泳衣、健美服、羽绒服、登山服衣料的最佳选择。锦纶常与其它纤维混纺或交织，以提高织物的强度和坚牢度。除了在衣着和装饰品方面的应用外，还广泛应用在工业方面如帘子线，传动带，软管，绳索，渔网，轮胎，降落伞等。
聚酰胺纤维即锦纶的优点如下：
1、强度高耐磨性好锦纶织物的最大优点是结实耐磨，耐磨性能居各类织物之首，比同类产品其它纤维织物高许多倍，它是制作耐磨擦制品的理想材料；
2、重量轻锦纶织物密度小，织物轻，在合成纤维织物中仅列于丙纶、腈纶织物之后，重量比棉、粘胶纤维要轻；因此，适合制作登山服、冬季服装等；
3、弹性好，耐疲劳破坏锦纶织物的弹性及弹性恢复性极好，定型、保型程度仅次于涤纶；
4、染色性好锦纶比涤纶染色性好；
5、耐碱性和耐还原剂作用好不怕霉，不怕虫蛀；
6、耐低温锦纶长丝具有良好的耐低温性能，在零下70℃以下时，其回弹性变化也不大。
连裤袜又称紧身袜、连袜裤，是紧包从腰部到脚部躯体的袜子，同长袜一样，连裤袜材质很多，有棉质、尼龙、羊毛混纺等。由尼龙或氨纶制作的连裤袜保持着原有的弹力、塑形的属性。但尼龙这种材料比较容易破碎，刮蹭在锐利物体上而破碎的情况十分常见。而聚酯纤维的连裤袜通常又存在着上述聚酯纤维的不足。特别是染色性较差，导致连裤袜的色彩品种很难丰富化，吸湿性差导致穿着体验不好。
发明内容
本发明的目的在于提供一种仿聚酰胺纤维的聚酯纤维裤袜及其制备工艺，以改善目前的尼龙连裤袜以及聚酯纤维连裤袜存在的上述问题。
本发明解决其技术问题所采用的技术方案是：
一种仿聚酰胺纤维的聚酯纤维裤袜，所述裤袜包括裤袜本体，裤袜本体由里纱和表纱交织而成，所述里纱由改性聚丙烯腈纤维和改性聚酯纤维混纺而成，所述表纱为氨纶；按重量百分比计，连裤袜本体各纤维原料的组成为：氨纶15~18%，改性聚丙烯腈纤维20~25%，改性聚酯纤维60~63%。
本发明的通过里纱和表纱交织配合，不仅包括保持了裤袜的弹性，同时能够通过改性聚丙烯腈纤维和改性聚酯纤维达到较好的吸湿性，从而及时地将身体的排汗吸收，有效改善穿着的舒适性。另外，通过改性提高实现较好的染色性能，从而丰富了产品的多样化。
上述改性的聚丙烯腈纤维和改性的聚酯纤维，可以达到聚酰胺纤维的的优点，如弹性好、染色性能好和耐碱性好。
作为优选，所述改性聚酯纤维由以下方法制备得到：
（1）将季戊四醇、乙二醇与对苯二甲酸配合成浆料，在催化剂作用下进行酯化反应，制备得到改性聚酯；季戊四醇与乙二醇的摩尔比为1:10~15；
（2）然后以制备的改性聚酯切粒为基料，在其中加入改性聚酯12~15wt%的聚对笨二甲酸丁醇酯，进行共混；将得到的共混物进行熔融纺丝；
（3）将纺丝得到的聚酯纤维首先采用氢氧化钠溶液进行浸泡清洗10~20min，氢氧化钠溶液的温度为33~37℃；然后用去离子水清洗干净，烘干后在反应液中进行反应3~5h；然后进行烘焙，最后清洗烘干得到改性聚酯纤维。
作为优选，氢氧化钠的浓度为0.05~0.1mol/L。
作为优选，所述烘焙温度为100~110℃。
作为优选，所述反应液为环糊精200g/L，柠檬酸80g/L，次亚磷酸钠30g/L。
作为优选，所述反应液为：所述环糊精为α环糊精、β环糊精或γ环糊精。
作为优选，所述改性聚丙烯腈纤维由以下方法制备得到：
（1）将聚丙烯腈纤维、氢氧化钠溶液同时加入捏合机内，控制温度38~42℃，碱化20~25min；
（2）乙醇溶液中超声清洗10~30min，然后用去离子水冲洗，真空干燥后，常温常压下等离子体处理；
（3）处理后的聚丙烯腈纤维进行接枝，将等离子体处理过的聚丙烯腈纤维浸在体积分数为50%的丙烯酸溶液中，在40~50℃下保持2~4 h后取出，清洗后于50~60℃下真空烘箱烘干，得到改性聚丙烯纤维。
本发明通过对聚酯纤维进行改性，具体是通过季戊四醇改性聚酯纤维，并与聚对苯二甲酸丁二醇酯进行共混改性，从而使得纺织的聚酯纤维的结晶度提高，从而使得其拉伸强度提高，同时，改性的聚酯纤维的断裂伸长率也具有一定的增加，在将改性的聚酯与聚对苯二甲酸丁二醇酯进行共混改性后，可以显著提高拉伸断裂强度，使得改性后的聚酯纤维韧性较好，有利于纺纱加工，增加了纺织品的耐磨性。
而对聚酯纤维进行环糊精的改性后，可以对聚酯纤维表面进行接枝，通过改性后的聚酯纤维具有良好的回潮率，从而改善了聚酯纤维的亲水性能。
而聚丙烯腈纤维主要是和聚酯纤维混纺提高整体柔软度、膨松度和色泽鲜艳度。而通过对聚丙烯腈纤维的改性，可以使得聚丙烯腈纤维具有导电性能，从而可以提高丝袜的抗静电性。
本发明的有益效果是：具有较好的吸湿性，并且能够达到较高的染色性能。
