Description

一种高撕裂强度无纺布的制造方法
技术领域:
本发明涉及无纺布生产技术领域,具体涉及一种高撕裂强度的针刺无纺布的制造方法。
背景技术:
无纺布又称不织布,是由定向的或随机的纤维而构成,因具有布的外观和某些性能而称其为布。
针刺无纺布属于无纺布的一种,一般以涤纶、丙纶短纤等原料制造,经过多次针刺加以适当热轧处理而成。
针刺无纺布根据工艺和克重不同,广泛用于过滤材料,土工布,服装棉,人造革基布,汽车隔音隔热材料等。但是普通针刺无纺布的撕裂强度较低,无法应用在鞋材,汽车革等需要较高撕裂强度的场合。
发明内容:
基于背景技术中提到的问题,本发明提出一种高撕裂强度无纺布的制造方法,制备的无纺布,兼具较高的撕裂强度和较好的柔软度,从而大大拓展无纺布的用途。
本发明采取的技术方案如下:
一种高撕裂强度无纺布及其制造方法,其特征在于,包括以下步骤:
(1)制备无纺布:
以100%涤纶短纤为原料,依次将涤纶短纤开松、梳理、铺网、针刺,制备克重250克/平方的针刺无纺布;
(2)含浸:
含浸液制备:包括按质量百分比的下述组成
丙烯酸酯 10~15%
柔软剂 0.1~0.5%
余量为水;
含浸工艺:将制备的针刺无纺布以9米/分钟匀速通过含浸液,使针刺无纺布在含浸液中充分浸润;
(3)后处理:
将含浸处理后的针刺无纺布,以9米/分钟的速度,依次通过轧干、预烘干、拉幅、烘干,并将表面烫平压光得成品,其中:
轧干力度为3-6公斤力;
预烘干温度100-120℃;
烘干采用四段烘干,烘干温度分别为:烘干温度依次为135-140℃、145-150℃、155-160℃、165-170℃.
作为优选的设置:
所述含浸液包括按质量百分比的下述组成:
丙烯酸酯 12%
柔软剂 0.2%
余量为水.
所述柔软剂为硅油柔软剂,特别优选为氨基改性硅油柔软剂。
所述四段烘干依次为135℃、150℃、160℃、170℃。
本发明的有益效果如下:
本发明选择丙烯酸酯与硅油柔软剂按照一定比例混合,对无纺布先进行含浸处理,含浸处理后的无纺布,再经过轧干、预烘、拉幅、及多道烘干工艺,制备的无纺布产品,由于丙烯酸酯具有良好的透明性,稳定性和力学性能,结合本发明的后处理工艺,能有效提高无纺布的抗撕裂性能,另一方面,柔软剂的加入,及后处理工艺的设置,能够有效改善丙烯酸酯造成的布面发硬问题,使无纺布的手感更加蓬松和柔软。
以下结合具体实施方式对本发明做进一步说明。
具体实施方式
下面将具体实施例来详细说明本发明,在此本发明的示意性实施例以及说明用来解释本发明,但并不作为对本发明的限定。
实施例1:
(1)制备无纺布:
以100%涤纶短纤为原料,采用常规的针刺生产工艺,依次将涤纶短纤开松、梳理、铺网、针刺,制备克重250克/平方的针刺无纺布。
(2)含浸:
含浸液制备:包括按质量百分比的下述组成
丙烯酸酯 10~15%
氨基改性硅油柔软剂 0.1~0.5%
余量为水。
含浸工艺:将制备的针刺无纺布以9米/分钟匀速通过含浸液,使针刺无纺布在含浸液中充分浸润。
(3)后处理:
将含浸处理后的针刺无纺布,以9米/分钟的速度,依次通过轧干、预烘干、拉幅、烘干,并将表面烫平压光得成品,其中:
轧干力度为3-6公斤力;
预烘干温度100-120℃;
烘干采用4段烘干,烘干温度分别为:再通过烘干机烘干,烘干方式采用4段烘干,烘干温度依次为135-140℃、145-150℃、155-160℃、165-170℃.
实施例2:
采用实施例1的制备方法,调整丙烯酸酯含量,并测试其对产品撕裂强度的影响。
表1、含浸液用量对于产品性能的影响
如表1所示:将不同含浸液处理的无纺布,与未经含浸处理无纺布样品,使用纺织品电子强力测试仪对无纺布样品进行测试,发现常规250克/平方无纺布撕裂强度6-8千克力,使用丙烯酸酯含浸后的无纺布撕裂强度可以达到10千克力以上,撕裂强度提高幅度大于20%,经含浸液处理后的无纺布,可适用于鞋材,球革等需要高撕裂强力的用途。
丙烯酸酯用量对于产品的撕裂强度性能有显著影响,随着丙烯酸酯用量增加,产品的撕裂强度性能有显著提升,但含量超过15%时,撕裂强度性能提升不明显,综合产品性能和生产成本来看,最佳用量为12%。
实施例3:
采用实施例1的制备方法,调整硅油柔软剂用量,并测试其对产品撕裂强度的影响。
表2、硅油柔软剂用量对于产品性能的影响
序号 硅油柔软剂用量 丙烯酸酯含量 产品撕裂强度
实施例3-1 0.1% 12% 8-9千克力
实施例3-2 0.2% 12% 10千克力
实施例3-3 0.3% 12% 10千克力
实施例3-4 0.4% 12% 9-10千克力
实施例3-5 0.5% 12% 9-10千克力
实施例3-6 0.6% 12% 9-10千克力
如表2所示:硅油柔软剂用量对于产品的撕裂强度性能有较大影响,随着丙烯酸酯用量增加,产品的撕裂强度性能有显著提升,但含量超过0.2%时,撕裂强度性能提升不明显,综合产品性能和生产成本来看,最佳用量为0.2%。
实施例4:
采用实施例1的制备方法,调整后处理工艺参数,并测试其对产品撕裂强度的影响。
表3、后处理工艺对于产品性能的影响
如表3所示:
1、采用丙烯酸酯浸渍处理后的无纺布,其撕裂性能虽然能得到显著提高,但由于丙烯酸酯造成的布面发硬问题,布料手感欠佳;
2、本发明选择丙烯酸酯与硅油柔软剂按照一定比例混合,对无纺布先进行含浸处理,含浸处理后的无纺布,再经过轧干、预烘、拉幅、及多道烘干工艺,制备的无纺布产品,由于丙烯酸酯具有良好的透明性,稳定性和力学性能,结合本发明的后处理工艺,能有效提高无纺布的抗撕裂性能,另一方面,柔软剂的加入,及后处理工艺的设置,能够有效改善丙烯酸酯造成的布面发硬问题,使无纺布的手感更加蓬松和柔软。
