Description
技术领域
本发明属于纺织技术领域,具体涉及一种涤纶长丝与纤维素纱及交织单向导湿功能面料的生产方法。
背景技术
单向导湿织物是同时具备水分快速传导和定向传导两种特性的织物,能够在人体排汗后迅速将汗液传导至织物外表面蒸发,同时阻止外表面汗液回流,使皮肤面保持干爽。研究者们早在20世纪初就从鸟类的羽毛、植物的导管中获得启发,对单向导湿现象中的水分传输机理进行了研究,在目前已有的研究中,面料的单向导湿功能多采用助剂,通过将织物两面分别做内层大部分疏水整理,外层亲水整理,从而达到单向导湿效果,但后整理的效果多不够持久,经过数次洗涤后易消失,且织物涂层容易填充纤维间隙,导致织物透气性显著降低。
发明内容
本发明的目的在于提供一种涤纶长丝与纤维素纱及交织单向导湿功能面料的生产方法,用于解决现有技术中织物单向导湿效率低、透气性不佳且导湿效果不够持久的技术问题。
为了实现上述目的,本发明采用了如下技术方案:
本发明提供一种涤纶长丝与纤维素纱的生产方法,包括以下步骤:
将超疏水涤纶纤维按常规工艺合股加捻,得到改性超疏水纱;将改性吸水纤维按常规工艺合股加捻,得到改性吸水纱。
优选地,所述改性吸水纤维的制备方法,包括以下步骤:
P1:将10-20g壳聚糖溶解于1-2L、1wt%的醋酸水溶液中,在室温下搅拌5-7h,得到壳聚糖溶液;
P2:将50-100g植酸加入0.9-1.8L水中,再加入10wt%的氢氧化氨溶液调节pH至7.0,得到植酸溶液;
P3:将苎麻纤维在80-100℃、1mol/L的氢氧化钠溶液中洗涤20-40min,再用水洗涤3-5次,最后在50-70℃下干燥2-4h,得到洗涤苎麻;
P4:将洗涤苎麻置于壳聚糖溶液中浸泡5-15min,挤压,然后在50-70℃下干燥1-2h,再置于植酸溶液中浸泡5-15min,挤压,在50-70℃下干燥2-3h,得到预处理苎麻;
以上过程中,通过静电重力作用将阳离子电解质壳聚糖和阴离子电解质植酸快速沉积在洗涤苎麻纤维表面,同时植酸中和壳聚糖中的羟基和氨基与苎麻纤维表面羟基通过氢键进一步增强结合。
通过采用上述技术方案,苎麻纤维形成膨胀型阻燃体系,使其具有优良的阻燃性能。
P5:将40-80mL二乙烯苯、1-2g偶氮二异丁腈溶解于1-2L乙酸乙酯中,常温搅拌3-5h得到混合液;
P6:将预处理苎麻浸入混合液中,在90-110℃下反应12-36h后,冷却至室温,再用无水乙醇清洗3-5次,最后在50-70℃下干燥10-14h,得到再处理苎麻;
以上过程中,二乙烯苯通过原位聚合生成聚二乙烯苯覆盖在预处理苎麻表面。
P7:将再处理苎麻在功率为50-70W、波长为320-360nm的紫外灯下辐射12-36h,得到改性吸水纤维。
通过采用上述技术方案,在紫外线能量的作用下,聚二乙烯苯部分芳香环结构发生断裂,产生了自由基和离子,在紫外线照射下,聚二乙烯苯分子中的自由基和离子会与周围的氧、空气中的氧气发生反应,形成含氧官能团,如羟基和羧酸基,由疏水变为亲水,且使得苎麻纤维具有超低温吸水性,从而提高了水分蒸发率。
优选地,所述苎麻纤维细度包括30S、60S中的至少一种。
优选地,所述超疏水涤纶纤维的制备方法,包括以下步骤:
S1:将1-2g偶氮二异丁腈、25-50g N,N'-乙烯基双丙烯酰胺、20-40mL二乙烯苯溶解于1-2L的N,N-二甲基甲酰胺溶液中,以100-140r/min的振荡频率振荡处理40-80min后,在80-120℃下反应12-36h,然后在198-208℃下蒸发至恒重后,在50-70℃下干燥2-4h,进行研磨并过40-60目筛,得到共聚改性剂;
共聚改性剂的结构式如下:
以上过程中,偶氮二异丁腈作为引发剂,引发N,N'-乙烯基双丙烯酰胺、二乙烯苯发生自由基聚合反应。
S2:将20-40g共聚改性剂、8-12g聚二甲基硅氧烷、13-16g α-氰基丙烯酸甲酯加入10-20L乙酸乙酯溶液中,并以800-100W的功率超声处理10-30min,得到疏水混合液,将超细旦异形截面涤纶纤维在疏水混合液中浸泡8-12min,再在50-60℃下干燥6-12h,得到处理涤纶纤维;
S3:取处理涤纶纤维均匀分散在等离子体处理腔内;开启真空泵,待处理腔内真空度降至7.0Pa后打开气体阀,通入氮气、氧气或氩气,调节其流量为1.0-2.0L/min;待流量及真空度稳定后,以30-70W功率对处理涤纶纤维进行处理1-5min,得到超疏水涤纶纤维。
以上过程中,双丙烯酰胺基团与芳香链结合在聚二甲基硅氧烷基体上,构建了双功能共聚物网络,同时在空气中的水蒸气主要作为亲核试剂的作用下,α-氰基丙烯酸甲酯的聚合在几秒钟内完成,聚酯上的C─C键和C─O键被高能粒子打开,形成C─和O─活性位点,与表面的聚二甲基硅氧烷发生自由基聚合,使疏水膜稳定、固接至纤维表面。
优选地,所述超细旦异形截面涤纶纤维细度包括30D/48F、50D/72F中的至少一种。
优选地,所述超细旦异形截面涤纶纤维单丝的横截面包括十字型、Y型、三叶型中的至少一种。
本发明还提供一种交织单向导湿功能面料的生产方法,包括以下步骤:
步骤(1)设计织物组织:采用双层梭织面料织造方式;
步骤(2)选择纱线:外层采用改性吸水纱,内层选用改性超疏水纱;
步骤(3)将改性吸水纱和改性超疏水纱通过织造制得交织单向导湿功能面料。
优选地,所述步骤(3)中交织单向导湿功能面料的重量为170-194g/m2、厚度为0.56-0.74mm。
优选地,所述步骤(3)中采用双面圆纬针织机织造得到交织单向导湿功能面料;交织单向导湿功能面料由前后线圈组成,面料的组织结构为交替的肋纹图案排列,形成具有不同层次的凹凸结构的面料,并在双层织物的主疏水表面每隔两个组织加入一根亲水性纱线,提高面料的单向导湿能力。
综上所述,由于采用了上述技术方案,本发明的有益效果是:
1.本发明中通过超疏水涤纶纤维和改性吸水纤维纺成功能纱线,再交替交织,得到沿织物厚度方向形成不对称润湿梯度的面料,具有明显凹凸结构的织物中形成了具有储水能力的中间层,便于单向液体输送,防止反渗透,面料内层与皮肤接触层的凹凸组织,减少凸处组织与皮肤的接触点,增大空隙,增大空气与面料的接触面积,从而增加透气性;由于毛细管力,使液滴从内层疏水层渗透到外层亲水面料表面,制备的单向导湿的功能面料具有优异的单向导湿性能、力学性能和透气性。
2.本发明中聚二甲基硅氧烷具有低表面张力和良好的透气性,利用其穿透多孔结构,在涤纶纤维表面上设计微纳界面,同时N,N'-乙烯基双丙烯酰胺与二乙烯苯通过自由基聚合得到的共聚改性剂结合在聚二甲基硅氧烷基体上,构建双功能共聚物网络,同时稀释后的聚二甲基硅氧烷部分渗透到纤维与共聚改性剂之间的界面,甚至渗透到多孔结构内部,使其具有很强的附着力;由于聚二甲基硅氧烷和α-氰基丙烯酸甲酯的协同交联作用,可以在涤纶纤维表面形成坚固耐用的涂层;对于α-氰基丙烯酸甲酯涂层,由于乙酸乙酯溶液的存在,α-氰基丙烯酸甲酯与水蒸气完成的聚合会被延迟,更有利于形成交联网络来固定共聚改性剂,采用分层交联方法对聚酯纤维进行无氟疏水整理,形成稳定的低表面能互穿聚合物网络疏水层。
3.本发明中通过壳聚糖、植酸沉积在苎麻纤维表面,同时在苎麻表面覆盖聚二乙烯苯并在紫外线作用下将聚二乙烯苯由疏水变亲水制备了具有超低温吸水性、吸湿性、优良阻燃性、机械耐久性的苎麻纤维,从而提高面料的吸湿性和水分蒸发率,以及阻燃性。

测试结果如表2所示:
从表2可见,实施例七-九制备的功能面料a、b、c的透气性良好;由对比例三和实施例七-九可知,凹凸结构更能提高功能面料的透气性。结果表明,特种涤纶长丝交织的单向导湿功能面料仍表现出良好的透气性和舒适性,适当的透气性和优异的单向导湿的结合,得到性能优异的功能面料。
