Description

一种具有阻燃功能的基布生产工艺
技术领域
本发明属于基布制备技术领域，特别涉及一种具有阻燃功能的基布生产工艺。
背景技术
随着时代的发展与进步，人们对纺织材料性能的要求不断提高，对于基布的阻燃性能也有所提高，而阻燃功能基布主要是通过对织物进行阻燃处理，从而使得基布制成的织物具有耐久性；
目前的具有阻燃功能的基布生产过程中存在缺点，其阻燃效果在使用中会慢慢减弱，阻燃效果不好或者阻燃性能不稳定，从而使得基布的耐用性不高，使用寿命不长，同时阻燃基布在生产过程中的阻燃材料不环保，给使用带来不便，为此，提出一种具有阻燃功能的基布生产工艺。
发明内容
本发明的主要目的在于提供一种具有阻燃功能的基布生产工艺，可以有效解决背景技术中的问题。
为实现上述目的，本发明采取的技术方案为：
一种具有阻燃功能的基布生产工艺，其特征在于，该阻燃功能的基布生产工艺包括以下步骤：
步骤一、制成经纱、纬纱，首先将芳纶纤维经线采用双股单纱制成经纱，而后将经纱浸入一定含固率的丙烯酸类共聚物中，其含固率为30-50％，其次将阻燃涤纶长丝也采用双股单纱制成纬纱，而单纱的细度为186dtex，经纱与纬纱的密度为3000dtex，得到制成的经纱与纬纱。
步骤二、进行织造，将制得的经纱与纬纱放置在织机上相互交织成半成品基布后，将得到半成品基布进行退浆，将待要的水槽内投放生物酶，而后将半成品基布放入水槽内堆置，水的温度范围在40℃-60℃，时间为20-30min；而后进行水洗，烘干待用，得到半成品基布；
步骤三、进行浸轧和浸泡处理，将配制好的阻燃整理液投放在需要浸泡的池水内，而后将半成品基布放置在水池内进行两浸两轧，两浸两轧的轧余率为50-75％；再进行烘干，烘干温度在80-150℃，时间在3-5min；得到阻燃的半成品基布；
步骤四、进行定型处理，将得到的阻燃的半成品基布放置在烘房内进行拉幅烘干定型，焙房温度为140-180℃，时间为2-5min，冷却后即可完成阻燃功能的基布生产工艺，最终得到具有阻燃功能的基布。
优选的，步骤二中水洗时，首先采用浸渍同等温度的水进行漂洗8-10次，而后进行热水清洗，水温90℃-95℃，漂洗时长2-3min，最后采用冷水清洗,水温10℃-30℃，清洗时长2-3min。
优选的，步骤三中所述阻燃层由以下重量份的原料制成：阻燃剂10-35份，聚丙烯树脂20-25，氢氧化镁20-30份，表面活性剂0.5-2份，渗透剂5-8份，低温增塑剂2-3份，聚乙二醇二缩水甘油醚2-5份，其中阻燃剂为三氧化二锑、硼酸锌、氧化锌中的一种或多种组合，表面活性剂为脂肪醇聚氧乙烯醚渗透剂采用非离子渗透剂，低温增塑剂为己二酸二辛酯。
优选的，步骤三中的浸轧工艺中浸泡时间为60-180min，浸轧速度为15m/min，压力为0.5-2.0Mpa。
优选的，所述阻燃整理液的配制是先将阻燃剂、渗透剂、低温增塑剂以及表面活性剂按照质量比为500-600：50-85：1-3：4-7进行阻燃整理液的配置，而后依次加入聚丙烯树脂，氢氧化镁和聚乙二醇二缩水甘油醚并进行充分的搅拌，搅拌时间为60-240min。
与现有技术相比，本发明具有如下有益效果：该阻燃功能的基布生产工艺，通过增加浸泡阻燃液步骤，使得基布的阻燃效果佳，在阻燃整理液中添加了表面活性剂和阻燃剂，当二者渗透到纱线内部时，使基布上均匀的带有高量的阻燃成分，从而提高了阻燃整理液的性能，阻燃性能高，而且通过增加聚丙烯树脂，树脂与经纱之间兼容性好，使得后续经纱织造时不容易出现断丝的现象，同时通过两浸两轧进行阻燃整理液浸泡，使得基布中的阻燃整理液成本更加的全面、更加的均匀，成本低廉，阻燃效果好，具有良好的应用前景。
