性能分析
(1)印花水洗色牢度测试
印花水洗色牢度试验主要用于测试纺织品的水洗褪色掉色情况。具体方法为：对印花面料进行洗涤12分钟，再经漂洗，脱水自然干或烘干为一个循环，共需要测试6个循环，并做好每个循环后的测试结果，最终计算得出印花水洗色牢度指数。
(2)酸性墨水转移印花膜的抗老化测试
采用人工老化的方法测定酸性墨水转移印花膜的抗老化性能。将酸性墨水转移印花膜放入人工老化箱，箱内用紫外灯或氙灯照射,按时喷淋，干湿交替环境。放置规定时间后取出，测粉化，失光，变色程度。最终计算得到酸性墨水转移印花膜的抗老化性能。
对实施例1～3中的样本进行性能测试，其结果如表5中所示。
表5实施例1～3中测试结果表
实施例 印花水洗色牢度指数 抗老化性能指数
实施例1 46.21 58.24
实施例2 48.69 59.10
实施例3 55.36 61.16
对比例 44.88 56.52
由表5中可知，在未加入交联剂时，印花水洗色牢度指数为44.88，加入稳定剂后，印花水洗色牢度指数有增加的趋势；抗老化性能指数指数随着交联剂份量的增加而随之增加。
综上所示，实施例1～3中以实施例3为最佳实施例。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理能够在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖点相一致的最宽的范围。

2.如权利要求1所述的酸性墨水转移印花膜，其特征在于，所述交联剂包括过氧化二异丙苯、过氧化苯甲酰、二叔丁基过氧化物和过氧化氢二异丙苯。
3.如权利要求2所述的酸性墨水转移印花膜，其特征在于，所述油墨层的制备步骤包括：
步骤一、以所述油墨层的配方为基础称取各成分，得到原料；
步骤二、搅拌所述聚乙烯醇，边搅拌边加入室温下的去离子水；当聚乙烯醇在所述去离子水中分散均匀后，对所述去离子水进行升温至75～80℃，并继续搅拌，直至所述聚乙烯醇在去离子水中完全溶解，得到溶液A；
步骤三、将步骤二中制备得到的所述溶液A加入到不锈钢溶解釜中，向所述不锈钢溶解釜中加入聚乙烯和聚乙烯醇缩丁醛，在60～90rpm的搅拌速度下进行搅拌；分散均匀后，停止搅拌；保持一定的温度，将搅拌均匀的混合物进行过滤，自然冷却至室温；得到混合物B；
步骤四、将步骤三中得到的所述混合物B放入至三角烧瓶内；依次向所述三角烧瓶内加入：水性二氧化硅、水性聚氨酯和聚海藻酸钠；对所述三角烧瓶进行水浴恒温加热，温度控制在45～60℃，对所述三角烧瓶内的混合物进行高速搅拌，搅拌时间为30～60min，搅拌结束后，将所述三角烧瓶静置反应10～30分钟，出料，得到混合物C；向所述混合物C中加入适量份数的离型剂和交联剂，充分混合，制备得到所述油墨层；
步骤五、对制备得到的所述油墨层进行性能分析。
4.一种利用酸性墨水转移印花膜转移印花的印花方法，其特征在于，包括以下步骤：
S1：在制备得到的酸性墨水转移印花膜上涂布剥离层，将印花浆料均匀刮涂到所述剥离层上；烘干所述剥离层上待转移的印花浆料；用水性表面张力提升液润所述酸性墨水转移印花膜，浸润的时间为5～15min；
S2：对待印花的面料进行加热，加热至70～80℃；采用热升华转印的印刷方法，对加热后的所述待印花的面料进行印花；将所述酸性墨水转移印花膜涂布有印花浆料的一面与待印花面料进行接触；所述热升华转印中转印的温度为160℃～175℃；
S3：所述剥离层剥离于所述酸性墨水转移印花膜，收卷剥离后的空白酸性墨水转移印花膜，对印花后的面料进行还原清洗、固色和焙烘。
