Description

一种阻燃防风絮片及其制备方法 技术领域
本发明涉及纤维产品技术领域，具体涉及一种阻燃防风絮片及其制备方法。
背景技术
絮片，指植物纤维、动物纤维或化学纤维制成的供保暖、隔热或防震用的片型绵状物。目前的各类絮片市面均有见，包括阻燃的、防风的、保暖的、抑菌的等等。而为了达到蓬松、多孔、轻质的效果，在絮片的生产过程中，往往会采取多层(至少3层)的结构，制备时需要一层一层地挤出成型，经过堆叠而成。此种方式生产絮片，一方面会导致絮片的生产工艺复杂，效率偏低，另一方面会导致絮片结构层之间增加了脱落的可能性，造成实际效果达不到预期。
申请号202110758929.0的发明专利《一种具有抗菌阻燃保暖功能的絮片及其制备方法》，提供了一种以熔融共混共挤方式制备的抗菌阻燃保暖絮片，但其各纤维之间混合程度较差，容易脱落。
申请号201910140874.X的发明专利《相变保暖絮片及其制备方法》，所提供的絮片，是通过无纺针刺方式相互连接的导湿纤维网层、蓄热纤维网层、隔热纤维网层组成的，但其各纤维网层之间分布并不均匀，严重影响了保暖效果。
申请号201811023385.8的发明专利《一种永久阻燃保暖碳化型絮片及其制备方法》，提供的絮片采用多种纤维制成，但其仍未层状结构，后续不仅需要开松，而且还需要梳理机梳理，工艺复杂，层状结构易脱落。
发明内容
本发明的目的是提供了一种制备方法简洁、高效、阻燃防风效果好，且不易脱落的阻燃防风絮片。
本发明的上述目的可采用下列技术方案来实现：
本发明提供了一种阻燃防风絮片，是以含有酰亚胺环的聚合物为基材，在喷丝阶段交织复合至少一种涤纶纤维得到的。
进一步的，上述的一种阻燃防风絮片，所述含有酰亚胺环的聚合物为聚酰亚胺纤维。
聚酰亚胺纤维拥有良好的可纺性，可以制成各类特殊场合使用的纺织品。由于具有耐高温特性、阻燃特性、不熔滴特性、离火自熄特性以及极佳的隔温特性，和其他纤维相比，是一种绝佳的隔温材料，同时，其做为阻燃防风絮片的基材，能够有效的与其它类别的纤维共同交织、产生更优的效果。
进一步的，上述的一种阻燃防风絮片，所述聚酰亚胺纤维为脂肪族聚酰亚胺纤维、半芳香族聚酰亚胺纤维和芳香族聚酰亚胺纤维中的一种或多种。
进一步的，上述的一种阻燃防风絮片，所述聚酰亚胺纤维的聚合度为20-300。
优选地，聚合度可以为20、50、100、150、200、250、300。
进一步的，上述的一种阻燃防风絮片，所述涤纶纤维选自阻燃粘胶纤维、阻燃涤纶纤维、阻燃涤纶中空纤维和低熔点复合纤维中的一种或多种。
阻燃粘胶纤维，通常是在粘胶纤维中加入阻燃剂制备得到的，其也能够做为絮片基材，效果略低于聚酰亚胺纤维(主要原因在于粘胶纤维的可纺性较差)，但以聚酰 亚胺纤维为基材，添加一定量的阻燃粘胶纤维，则能够发挥二者的共同特性，进一步提高了絮片的阻燃保暖性能。
阻燃涤纶纤维和阻燃涤纶中空纤维，均是经过改性处理的阻燃涤纶，二者阻燃效果好，在过火时，只熔融不燃烧，其极限氧指数通常较高，为可燃甚至难燃材料，但传统的阻燃涤纶，制备工艺复杂，添加量过高，从而导致成本极高，同时由于阻燃涤纶本身的特性，其质感较差，无法满足需要。
低熔点复合纤维，是指聚酯和改性聚酯复合纺丝生产的低熔点纤维，可在更低的温度下熔融和其他纤维粘合，其粘合性、加工性和弹性均要好于普通纤维。
进一步的，上述的一种阻燃防风絮片，按照重量份计，聚酰亚胺纤维为12份-28份，涤纶纤维为38份-66份。

表2
Figure PCTCN2022084906-appb-000003
实施例和对比例中所涉及的会影响本发明最终技术效果(质量、热阻、蓬松度、压缩弹性回复率、阻燃性能等)的关键技术因素，包括以下几个方面：
1、不添加基材聚酯纤维(对比例1)；
2、聚酰亚胺纤维的聚合度为10(对比例2)、350(对比例3)；
3、涤纶纤维选自：
1)单一涤纶纤维：阻燃粘胶纤维(实施例5)、阻燃涤纶纤维(实施例6)、阻燃涤纶中空纤维(实施例7)、低熔点复合纤维(实施例8)；
2)两种涤纶纤维：阻燃粘胶纤维+阻燃涤纶纤维(实施例9)、阻燃粘胶纤维+阻燃涤纶中空纤维(实施例10)、阻燃粘胶纤维+低熔点复合纤维(实施例11)、阻燃涤纶纤维+阻燃涤纶中空纤维(实施例12)、阻燃涤纶纤维+低熔点复合纤维(实施例13)、阻燃涤纶中空纤维+低熔点复合纤维(实施例14)；
3)三种涤纶纤维：阻燃粘胶纤维+阻燃涤纶纤维+阻燃涤纶中空纤维(实施例15)、阻燃涤纶纤维+阻燃涤纶中空纤维+低熔点复合纤维(实施例16)、阻燃粘胶纤维+阻燃涤纶中空纤维+低熔点复合纤维(实施例17)；
4、聚酰亚胺纤维的百分占比为10％(对比例4)、30％(对比例5)；
5、阻燃粘胶纤维的百分占比为25％(对比例6)、35％(对比例7)；
6、阻燃涤纶纤维的百分占比为2％(对比例8)、15％(对比例9)；
7、阻燃涤纶中空纤维的百分占比为3％(对比例10)、15％(对比例11)；
8、低熔点复合纤维的百分占比为2％(对比例12)、10％(对比例13)。
验证试验的设置概括如下表3所示：
表3
Figure PCTCN2022084906-appb-000004
Figure PCTCN2022084906-appb-000005
表3中，所有空白部分的数据均与实施例4(最优选技术效果)相同。验证试验中各实施例和对比例的应用效果概括如下表4所示：
表4
Figure PCTCN2022084906-appb-000006
Figure PCTCN2022084906-appb-000007
从表3-4中各项实施例、对比例以及应用效果检测结果可以看出，
1、以检测结果看，实施例4为所有实施例和对比例中各项指标最好的；
2、对比例1(无聚酰亚胺纤维)为所有实施例和对比例中综合各项指标最差的，明显低于表2中所给出的各项标准值，难以达到标准要求，充分说明聚酰亚胺在本发明中起到了关键作用；
3、对比例2-3、对比例4-5、对比例6-7、对比例8-9、对比例10-11、对比例12-13分别为本发明所提供的各技术要点所要求保护的范围之外的任选点值，其效果明显低于实施例2-4。
申请人于2016年8月、2017年1月、2017年8月委托国家纺织制品质量监督检验中心，依据GB/T 11048-2008A法和B法，对本发明所述的各实施例的阻燃防风絮片的保温性能进行了检测，检测项目包括热阻(m 2·K/W)、克罗值、折算保温率(％)及传热系数(W/(m 2·K))。
申请人还于2017年1月委托国家纺织制品质量监督检验中心，依据GB/T 5455-2014，对本发明所述的各实施例的阻燃防风絮片的垂直燃烧性能进行了检测，检测项目包括损毁长度(mm)、续燃时间(s)、阴燃时间(s)、燃烧特征及有无滴落物。
申请人还于2016年6月委托国家纺织制品质量监督检验中心，依据FZ/T 64020-2011(复合保温材料，化纤复合絮片)和FZ/T 73023-2006(抗菌针织品)，对本发明所述的各实施例的阻燃防风絮片的产品性能进行了检测，检测项目包括压缩弹性率(％)、水洗性能外观变化、保温性-热阻(m 2·K/W)、透气率(mm/s)、单位面积质量(g/m 3)、蓬松度(cm 3/g)、金黄色葡萄球菌(ATCC 6538)抑菌率(％)-洗涤50次后、白色念珠菌(ATCC 10231)抑菌率(％)-洗涤50次后、大肠杆菌(8099)抑菌率(％)-洗涤50次后。
综合比较本发明所提供实施例中(尤其是实施例4)的阻燃防风絮片产品的各项检测结果可以看出，本发明所提供的阻燃防风絮片，其阻燃效果、蓬松效果、防脱效果、保温效果、透气效果、质量以及抑菌率等各项指标均明显优于对比例，也明显优于现有产品。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
