技术领域
本发明公开了一种导水涂层纤维的制备方法，属于保水材料制备技术领域。
背景技术
全球荒漠化日趋严重，已导致受灾人口达10亿之多。20世纪50年代以来，我国的荒漠化面积一直呈扩展趋势，80年代中期到90年代中期已达到每年2460km2，相当于每年吞噬一个中等县的土地面积，进入90年代后期扩展速度更是有增无减，据遥感资料统计，我国荒漠化土地面积以年均2100km2的速度增加，涉及全国470个县(市、旗)。治理荒漠化的根本途径是生态恢复，生态恢复的关键因子是水分条件。然而，荒漠化地区恰恰是水资源严重缺乏，地表温度高，年蒸发量是降水量的几十到几百倍，巨额投入的频繁浇水不仅无法保证苗木成活，还导致有限水资源的巨大浪费。因此，恢复植被、植树造林，进行生态恢复建设，合理的水分是首要条件。抗旱节水的生态恢复技术是解决该难题的根本性途径。
涂层导水纤维由天然植物纤维经涂层化处理而制备，具有随外界环境变化而可控导水的性质。将涂层导水纤维与高分子材料复合后得到的复合薄膜包装一定水后，埋入植物根部后，涂层纤维可根据环境和植物生长的需要，可控地将水由膜内传向膜外，满足植物生长的需要。将涂层导水纤维应用于干旱和半干旱地区的植树造林，可合理利用该地区有限的水资源。但是现有的导水涂层纤维材料单一，材料表面规整致密，导致放湿性能差且材料自身其成膜性差，湿容量小，无法满足现有环境对材料的需求，所以制备一种高效导水放湿，成膜性能较好的导水涂层纤维很有必要。
发明内容
本发明主要解决的技术问题：针对现有材料表面规整致密，导致放湿性能差且材料自身其成膜性差，湿容量小，无法满足现有环境对材料的需求的问题，提供了一种导水涂层纤维的制备方法。
为了解决上述技术问题，本发明所采用的技术方案是：
（1）按质量比1:5，将棕榈丝与冰醋酸搅拌混合，水浴加热，过滤得滤渣，洗涤、干燥，得干燥棕榈丝；
（2）按重量份数计，分别称量45～50份去离子水、1～2份四丙基溴化胺、3～5份正硅酸乙酯和3～5份氧化钠搅拌混合，调节pH至8.5，搅拌混合得改性液；
（3）按质量比1:10，将干燥棕榈丝添加至改性液中，搅拌混合并晶化处理，过滤得滤饼，洗涤、干燥，得干燥改性纤维；
（4）将干燥改性纤维置于管式气氛炉中，煅烧处理，静置冷却至室温，得中空支撑体纤维；
（5）按重量份数计，分别称量45～50份去离子水、10～15份明胶、3～5份聚酰胺-胺型树枝状高分子和10～15份500目蒙脱土粉末置于烧杯中，搅拌混合得涂覆浆料，将涂覆浆料涂覆至中空支撑体纤维表面，待涂覆完成后，干燥，即制备得一种导水涂层纤维。
步骤（1）所述的水浴加热温度为55～60℃。
步骤（2）所述的调节pH采用的是质量分数10％氢氧化钠溶液。
步骤（3）所述的晶化处理温度为185～190℃。
步骤（4）所述的煅烧处理为，按3℃/min升温至550～600℃，保温煅烧3～5h。
步骤（5）所述的涂覆浆料涂覆厚度为0.3～0.5mm。
本发明的有益效果是：
（1）本发明采用的粘结剂为树形水溶性高分子，通过该水溶性高分子具有的高度交联的三维网状结构和其大分子链上具有的大量亲水基团，可以吸收大量的自由水储存，有效改善涂层材料的空间网络结构，通过溶胀改性材料的透水性和成膜性能，有效提高材料对水分的吸附和包裹作用；
（2）本发明通过具有分子筛结构的包覆膜包覆中空的棕榈纤维材料，通过其具有的透水性和均一的层间距，使材料的孔径有效增大，改善涂层材料孔径分布，且与三维网状结构的粘结剂进行充分的结合，提高材料的导水性能。

将本发明制备的实例1，2，3分别与肉苁蓉一同栽种，并对其成活率进行测试和分析，具体测试如表1所示：
选取株高为1m左右的成年梭梭，在其向阳侧距离植物0.2m处挖坑，
坑深为0.5m。将自制接种包置于坑底部后将渗灌滴头置于其正上方3cm，然后埋沙土覆盖，埋入种子包后浇足一次水。此后不再浇水，，接种期6个月共浇水4次。试验设计为每组各接种100棵，共计300棵，定期统计接种率。
