Description

一种织物快干添加剂组合物及包含该组合物的织物洗涤剂
技术领域
本发明涉及洗涤剂领域，尤其涉及一种织物快干添加剂组合物及包含该组合物的织物洗涤剂。
背景技术
在织物处理过程中，洗涤-脱水-干燥是极为常见的一道工序。如在家庭洗涤过程中，织物经脱水后需要进行干燥处理，而加热干燥的方式会消耗大量的能源，悬挂晾干的方式则会消耗消费者大量的时间，尤其是在梅雨季节的高湿度环境下。潮湿环境中，织物还易滋生细菌/霉菌，影响服用健康。缩短织物的干燥时间，既能够节能减碳，提高生产效率，应用到洗涤产品中，还能提升消费者的生活品质，具有社会效应和市场需求。影响织物干燥速度的因素较多，但经研究发现，织物脱水后的带液率对织物的干燥时间影响较大。带液率越低，相对的干燥时间也会越短。
专利CN 103764811 A中提出，使用包含有以N-(-CH2-CH(OH)-CH2-Cl)2为末端的重均分子量小于5000的线性聚醚聚合物的组合物洗涤织物至少3次，使线性聚醚聚合物沉积在织物上，可减少织物的干燥时间。但是该组合物需要累积处理才有效果，效率较低，并且其有益组分的生物可降解性差，不利于环保。而且该组合物作为衣物柔顺剂使用，需要增加一道使用工艺。因此，直接使用洗涤剂洗涤衣物，并获得缩短织物干燥时间的效果，具有市场需求。
发明内容
为了解决上述技术问题，本发明提供了一种织物快干添加剂组合物及包含该组合物的织物洗涤剂，该组合物将特定规格的微晶纤维素悬浮分散到体系中，方便添加到各类产品中，且在处理过程中微晶纤维素沉积到织物表面，可显著降低织物脱水后的带液率，进而缩短干燥时间，实现快干效果。
本发明的具体技术方案为：
第一方面，本发明提供了一种织物快干添加剂组合物，包括以下质量百分含量的组成：10-20％的微晶纤维素，0.1-5％的分散稳定剂，1-10％的表面活性剂；余量为水。
处理后的织物带液率是影响干燥时间的关键因素。因此，降低织物带液率，能显著缩短织物的干燥时间。本发明在研究过程中进一步发现：使用特定规格的微晶纤维素能显著降低织物在洗涤过程中的带液率。其大致原理为：在漂洗过程中，微晶纤维素沉积到织物上，使织物疏水性增加，减弱了织物对水的吸附结合能力，降低了织物脱水后的带液率，同时在晾晒或烘干环节中，织物与水的作用力弱，水分更容易挥发，进而缩短了干燥时间。
但微晶纤维素为高度有序的结晶结构，其内部在氢键的作用形成较强的作用力，难以在水溶液中溶解，同时由于其粒径较大，直接添加易在体系中受重力作用发生沉降。为此，本发明通过筛选使用合适的分散稳定剂将微晶纤维素稳定分散到体系中，赋予微晶纤维素良好的使用便利性；最终所得的织物快干添加剂组合物具有良好的稳定性和流动性，能方便地添加到各类形式的产品中，并赋予产品快干功效。例如将上述织物快干添加剂组合物添加到织物洗涤剂中，能显著降低洗涤过程中的织物带液率，缩短干燥时间。
作为优选，所述微晶纤维素为纤维素I型，平均粒径为10-100μm，结晶度为55-85％，聚合度为100-250。
作为进一步优选，所述微晶纤维素的平均粒径为30-80μm，结晶度为60-80％，聚合度为150-225。
本发明团队发现，并非任意规格的微晶纤维素都能够取得理想的效果，通过实验发现微晶纤维素规格对于快干效果影响较大，只有当微晶纤维素在上述特定规格范围内时快干效果才较为显著。而不在特定规格范围内的微晶纤维素几乎不具备快干效果(甚至起到反作用，详见具体实施部分)，可能是受其沉积能力、成膜性、疏水化能力等因素有关。
作为优选，所述分散稳定剂为疏水改性聚丙烯酸酯聚合物、疏水改性聚氨酯聚合物、聚酰胺蜡、聚丙烯酸类聚合物、聚酯聚醚聚合物和黄原胶中的一种或多种。
上述分散稳定剂可在体系中通过疏水链缠结、氢键、二级作用力等多种分子间相互作用形成三维网格结构，对微晶纤维素颗粒起到悬浮防沉降作用。
作为优选，所述表面活性剂为氢化蓖麻油聚氧乙烯醚、脂肪醇聚氧乙烯醚、烷基糖苷、聚氧乙烯聚氧丙烯嵌段型聚醚和聚氧乙烯失水山梨醇中的一种或多种。
作为优选，25℃下组合物的屈服应力值不小于0.5Pa。
微晶纤维素为水不溶颗粒，因此需要体系维持一定的屈服应力以保证微晶纤维素能被良好地悬浮稳定在体系中。若体系的屈服应力值过小，则微晶纤维素会沉降析出。
第二方面，本发明提供了一种上述组合物的制备方法，包含以下步骤：用适量的水溶解分散稳定剂和表面活性剂，再添加微晶纤维素搅拌至均匀，而后调节体系pH在5.0-9.0之间。
第三方面，本发明提供了上述组合物的应用：可将所述组合物与洗涤剂直接配合使用，或加入液体洗涤剂中，或包埋于多腔洗衣凝珠内，或与洗衣粉浆直接混合后喷粉制粒。
第四方面，本发明提供了一种含有上述组合物的织物洗涤剂，所述组合物在织物洗涤剂中的质量百分含量为1-10％，且织物洗涤剂中包括至少一种除组合物中表面活性剂外的基础表面活性剂，所述基础表面活性剂为阴离子表面活性剂、非离子表面活性剂和两性离子表面活性剂中的一种或多种。
本发明团队通过研究发现，在洗涤剂中添加至少1％的具有特定规格的微晶纤维素的织物快干添加剂组合物，才可使洗涤剂具有快速干燥效果，且随着添加剂量的增加，效果逐渐明显，但也会逐渐到达平台。
作为优选，所述织物洗涤剂还包括洗涤助剂，所述助剂选自香精、酶制剂、聚合物、遮光剂、盐、增白剂、防腐剂、螯合剂和色素中的一种或多种。
与现有技术相比，本发明具有以下技术效果：本发明使用特定规格的微晶纤维素能显著降低织物在洗涤过程中的带液率；并同时使用合适的分散稳定剂将微晶纤维素稳定分散到体系中，赋予微晶纤维素良好的使用便利性；最终所得的织物快干添加剂组合物具有良好的稳定性和流动性，能方便地添加到各类形式的产品中，并赋予产品快干功效。

具体实施例及测试实验
实施例中用到的试剂信息如下：
MCC1：微晶纤维素平均粒径为12μm，结晶度为85％，聚合物度为230；
MCC2：微晶纤维素平均粒径为36μm，结晶度为75％，聚合物度为180；
MCC3：微晶纤维素平均粒径为75μm，结晶度为64％，聚合物度为220；
MCC4：微晶纤维素平均粒径为95μm，结晶度为57％，聚合物度为120；
MCC5：微晶纤维素平均粒径为150μm，结晶度为68％，聚合物度为220；
MCC6：微晶纤维素平均粒径为30μm，结晶度为50％，聚合物度为170。
按照以下方法制备实施例1-6：用适量的水溶解分散稳定剂和表面活性剂，再添加微晶纤维素搅拌至均匀，而后调节体系pH在7.5±0.3。
实施例1-6
疏水改性聚丙烯酸酯聚合物 0.5
氢化蓖麻油聚氧乙烯醚 5
微晶纤维素MCC1-6 15
防腐剂 0.1
水 至100
织物快干添加剂组合物的屈服应力于25℃采用流变仪进行测定，条件为：50mm椎板，角度1度，测量间距98μm，保温两分钟，剪切速率范围0.01-1000s-1。上述添加剂组合物的屈服应力值为1.5±0.2Pa。
织物快干添加剂组合物的稳定性按照如下方式进行：将组合物置于45℃±2℃的恒温箱中放置24小时，取出恢复至室温后观察。
结果显示，实施例1-6的组合物均具有良好的稳定性，体系无析出不分层。
按以下比例制备织物快干添加剂组合物，即实施例7-15：
Figure BDA0003071727650000041
Figure BDA0003071727650000051
由上述结果可知，织物快干添加剂组合物中当微晶纤维素含量超过20％时，体系已经不具备流动性，极大地影响了体系的使用效果。而当体系的屈服应力值小于0.5Pa时，体系的稳定性较差，高温条件下会发生微晶纤维素的沉降析出。
织物快干添加剂组合物在洗涤剂中的快速干燥效果采用如下方法进行测定：
1.用硬度为250ppm(Ca2+∶Mg2+＝3∶2)的硬水配制1000ml浓度为0.2％的洗涤剂，放入布样(重量计为W0)，于立式去污机中75rpm、30℃洗涤20min。
2.用1000ml硬度为250ppm(Ca2+∶Mg2+＝3∶2)的硬水漂洗3次。
3.使用滚筒洗衣机进行脱水，脱水转速为1000rmp，时间为7min。
4.将步骤3脱水后的织物进行称量(重量计为W1)，计算织物的带液率，然后放在湿度为70-80％，温度为25±1℃下进行干燥，每隔一段时间称取织物重量然后换算成织物的实时带液率，以8％为干燥终点，计算干燥时间。
带液率计算公式为：带液率＝(W1-W0)/W0×100％。
织物快干添加剂组合物在粉状洗涤剂中的快干效果评价按照上述方法进行评测，所用的粉状洗涤剂组成如下：

各组的快速干燥结果如下：

测试例2(含实施例2的组合物) 182％ 181min

测试例5(含实施例5的组合物) 198％ 206min
测试例6(含实施例6的组合物) 210％ 220min
对照例1 206％ 212min
织物快干添加剂组合物在液体洗涤剂中的快干效果评价按照上述方法进行评测，所用的液体洗涤剂组成如下：

各组的快速干燥结果如下：

测试例7(含实施例1的组合物) 182％ 180min
测试例8(含实施例2的组合物) 178％ 176min
测试例9(含实施例3的组合物) 168％ 164min
测试例10(含实施例4的组合物) 186％ 183min
测试例11(含实施例5的组合物) 199％ 202min
测试例12(含实施例6的组合物) 208％ 215min
对照例2 201％ 208min
由上述结果可以看出：只有添加了特定规格的微晶纤维素的织物快干添加剂组合物(实施例1-4)才能使洗涤剂具有明显的快速干燥效果，其添加到粉状洗涤剂或液体洗涤剂中，织物经洗涤脱水后的带液率有明显下降，干燥时间显著缩短；但微晶纤维素的粒径和结晶度不在特定规格范围内(实施例5粒径偏大，实施例6结晶度偏低)，则基本没有快速干燥的效果。
实施例3在液洗洗涤剂中不同添加量对织物洗涤的快速干燥效果进行了评测，所用的液体洗涤剂组成如下：
Figure BDA0003071727650000071
快速干燥结果如下：

测试例13 190％ 189min
测试例14 185％ 183min
测试例15 173％ 174min
测试例16 171％ 168min
对照例2 201％ 208min
由上述结果可以看到，在洗涤剂中添加至少1％的具有特定规格的微晶纤维素的织物快干添加剂组合物，就能使洗涤剂具有快速干燥效果，且随着添加剂量的增加，效果逐渐明显，但也会逐渐到达平台。
本发明中所用原料、设备，若无特别说明，均为本领域的常用原料、设备；本发明中所用方法，若无特别说明，均为本领域的常规方法。
以上所述，仅是本发明的较佳实施例，并非对本发明作任何限制，凡是根据本发明技术实质对以上实施例所作的任何简单修改、变更以及等效变换，均仍属于本发明技术方案的保护范围。
